Parsing the LCD video wall screen application in various fields

With the development of all walks of life, promotion of computer technology, as a LCD video wall screen service providers have to improve, people on picture clarity and resolution, high brightness, high contrast are the pursuit of more perfect. As the change of demand, all kinds of large screen in different sectors have different advantages.

There’re variety of LCD video wall models in the market.  Usually it can be category by total bezel gap, resolution, panel dimension, diagonal, contrast ratio, LED backlight and cost. Multiple video wall screens plus other components combined to video wall system.  If customer make it as built-in video wall processor, there’ll be no need separate matrix video wall controller. In this case, the system include signal splitter(for example HDMI splitter ) we can only Stitching a signal at the same time, we can also external matrix do more signal any stitching at the same time. This series is widely used on a large screen, involving multiple areas, can be used for security, command center display screen display, the entertainment industry, enterprise information display, advertising media, convention and exhibition center display, factories and mines, electric power, water conservancy, education, organizations, army and mine industry, etc. This large screen has a variety of installations, can be wall-mounted, embedded, floor cabinets, hoisting, TV ark, etc. This series of splicing screen can be set in a manual, timing, cruise, alarm plan and kaleidoscope demonstration, intelligent temperature control and alarm, communication malfunction automatically detect, and other functions, can be full screen, much separately display signal, the whole screen, display in any combination.

LCD video wall screen is currently the most high-end, the most ideal display device, its superior performance, has won a wide recognition. A traffic monitoring center the joining together of curtain wall, for example, more of the time required to watch all images of point to point at the same time, the abnormal situation when a monitory point, can quickly zoom to full screen for all of the monitoring center to watch at the same time. This request in practical application, the splicing curtain wall in the big screen and small screen should be achieved good display effect. And size combination, use more flexible; Stable long service life, low maintenance cost. So many advantages, for the user unit, LCD video wall screen is the best choice.

The LCD video wall installation site must meet 5 conditions

Ultra narrow bezel LCD video wall display experience can bring you a better display effect, ultra wide Angle of view, the display of large capacity, in all aspects of life are better visual enjoyment. To ensure the smooth progress of the project equipment installation on site must meet the following conditions:

1. Environmental requirements

Installation ground smooth solid, strong bearing capacity, deformation, due to the LCD video wall stent generally direct contact with the anti-static floor, need to make sure that the ground bearing stress deformation for a long time.

2, Light requirements

Concealed lighting recommended canister light, the light should not be pointed directly at the screen direction, distance from the screen to keep 3 meters away, lest affect the projection effect; Second should avoid direct sun light.

3, Go line and trough

Low voltage cables (VGA video network serial mouse and keyboard extension cords, etc.) should be separated with high voltage cable line, to avoid interference. If it is to use go trough can’t share a go trough, trough separate walk should be different.

4, Power supply

Considering the system may encounter special would happen break point again electrify current shock, LCD video wall monitor unit itself has power protection design, guaranteed the normal safe operation of equipment; System of power supply for AC 220 v + / – 5%; With a protective earthing line three eye socket, socket number related to splice screen number; Power supply voltage should be stable and reliable; System equipment should have good grounding, grounding resistance < 2 Ω, ensure encountered lightning strike and other special situation when the equipment is not damaged.

5, System environment

1) time the good temperature and humidity control room requirements. Working environment temperature is 23 ℃ + / – 5 ℃, relative humidity 20% to 80%. Joining together back to have air conditioning.

2) before and after the video wall, air-conditioning temperature and humidity should be transferred to the same scale, in order to ensure that splicing wall heat dissipation and splicing flatness of the screen.

3) Video wall for clean room, dust-proof.

4) the fire sprinklers away from splicing wall as much as possible, and to use the spray fire extinguishing agent

portable digital signage

The Portable digital signage for retail commercial use

The portable digital signage , as a kind of particular application form, has become the digital signage application different from other commercial shows the application of a typical representative.

With the highlight attributes of the digital signage applications, its original independent industry increasingly blurred. Especially in the retail industry, the application of portable digital signage is regarded as the digital sign applications permeate “pioneer”.

Based on traditional digital marketing idea, portable digital signage of the complexity of the application environment in public places with a strong ability to adapt, such as vertical LCD advertising display mostly adopts a solid aluminum alloy and glass as case, the integration of design, dust-proof, effectively prevent man-made scratch, etc., to ensure that the product in the densely populated environment security, stability.
At the same time, the retail industry, due to dispersion and the application range is extensive user base, the market application of personalized characteristic is very outstanding, while portable digital signage has flexibility and the application needs to keep a high degree of fit, it is also the’s retail customers an important reason.


Outdoor digital signage

Outdoor digital signage develop rapidly in commercial display

Outdoor digital signage develop rapidly

With the progress of social technology, outdoor advertising is gradually from the traditional static billboards rapidly to dynamic digital transformation. Outdoor digital signage spread information will not be affected by the weather and can bring good visual and auditory enjoyment, can be widely applied to outdoor advertising, outdoor public information release, outdoor media, touch interactive query in areas such as all-weather, greatly improve the picture administrative levels sense, can better details. As the outdoor digital signage usage scenarios from half outdoor to full outdoor gradually expanded, its challenges and more diversified.

The brightness of the outdoor digital signage industry standard is needed in the shining of the skylight environment 1500 CD/M2 (later referred to as “CD) can call it outdoor displays. Recently, a German professional digital signage consultants a set of evaluation for outdoor display. Through a set of CD from 450 to 3000 CD display contrast effects can be intuitive feel, only 1500 CD the brightness of the display effect under the condition of the sun. Means that only 1500 of the CD of display brightness can cause decay and loss of visual information, cannot have the effect of attract attention. However, Samsung OHD series outdoor display brightness can be as high as 3000 CD, full beyond industry standard double, even in the face of midday light can also ensure clear and bright display, make image “light”.
“Anti glare” as a screen technology, has been widely used in mobile phones, tablet and display, etc. In daily life. But for outdoor digital signage, if you don’t want to be a “public pier glass,” requires higher anti glare index. Especially when applied in traffic industry information display scenario, if the display is not clear or light refraction, etc., will cause great hidden trouble of road safety. Samsung outdoor digital signage through the use of unique technology, by enhancing image contrast and Samsung exclusive patented reflex eliminate membrane, can effectively enhance your visibility and reduce the screen of specular reflection. At the same time, Samsung outdoor digital signage is not only “anti glare,” also “polarized”. Through the application of the circular polarization technology, solve the traditional liquid crystal display in the human eye wear polarized sunglasses when viewed “show blind area” problem, more comprehensive protection to the road traffic safety.
Outdoor digital signage is an important terminal in urban informatization construction, wisdom is one of the important elements to build urban business card. The development of outdoor digital signage will provide the wisdom of the urban construction in China with strong boost.


Touch Everywhere Touch Monitor Or Bringing In The New Spring

From the advent of smart phones, touch industry ushered in the rapid development of this kind of way of human-computer interaction, quickly changed people’s life, for a while, touch everywhere, extend from smart phones to tablets, to many touch products in the field of business, can say people’s acceptance to touch and ushered in the new peak demand. So much demand, nature also contributed to touch the market boom, many manufacturers have begun to enter the field, therefore can be said to be the 2016 touch a peak of the market, but from the current form, touch the market upward trend has been insufficient, is now beginning to supply, price war multiplexes stage, believe touch market will soon be facing a big reshuffle.

Touch crazy bargain intelligent monitor or for a new spring

Why touch market rise so fast, the bottleneck period also come so fast? This is related to the industry’s technical threshold is not high, touch panel industry into the threshold is relatively low, and the thin film transistor liquid crystal display (TFT LCD) panel, expensive compared with yellow process, machine equipment, touch panel production equipment is very cheap, cause manufacturers, with competitors.

Manufacturer, the threshold is not high consequence is the price war play more and more fierce, peripheral manufacturers in order to get the order can only rely on price to win, a line manufacturers, although more quality assurance, but competition under the pressure, also can make a compromise on price, which reversed transmission peripheral manufacturers price again, thus forming a vicious circle. It reminds people of the LCD splicing in the field of the situation, because of the low barriers to entry the LCD splicing, so is also a low-margin market, and touch the market is similar, but the LCD splicing has deep into the red sea, and touch the market is just came to the shore, but declining profits will be a trend.

Touch competition intensifies, will lower the cost of the touch function, this is helpful to carry a touch function of equipment to reduce costs, consumer can use a lower price, buy good touch effect of equipment, including mobile phones, tablets and other products, but because of mobile phone basically is to see configuration, so touch cost advantage is not obvious, but for the touch display, is very obvious, in the case of without too much more money, people naturally prefer to buy a can touch display.

Now with touch display is divided into two kinds, one kind is only touch function display, is a kind of touch and the system (android) generally have at the same time, they all belong to the category of intelligent monitor. The concept of smart display is not too clear, but you can touch is clearly a function could not be neglected, and from the point of the current development situation, displays the future is to combine more equipment to use, not simply as a passive output display devices, so intelligent monitor is a development trend, and a touch of cost reduction, is to reduce the development of the intelligent monitor resistance.

Touch equipment main market at present actually concentrated in 10 inches below the market, competition is very fierce, similar to the larger screen touch touch display equipment, intervention of the manufacturer is less, so also higher profit margins, so touch display market, touch manufacturers concern. And touch the overall lower cost, also has brought new opportunities for intelligent display, after all, a touch is an important symbol of the intelligent monitor, intelligent display in 2017 will usher in a new spring? We have to wait and see.

The LCD Splicing Size Of Benefits Of Diversification

As the LCD splicing screen slowly spread, diversified development, the size of the LCD splicing have appeared in the current common size 40, 46, 55, 60, such as size, which is the most commonly used size. Scale among them, these are some splicing model, and according to the technology development, there have been some big size of the monomer, for example, the emperor of emperor ai electronic launch monomer, 70, 82 inches, are more widely used. The diversity of product size can better satisfy the diverse application environments, convenient for customer choice, also is more advantageous to the LCD splicing industry development. At the same time, the diversification of product size also means that the rapid development of industry, means that the industry have more capital and technology, continues to perfect the product line. With the diversification of products, narrower flat-fell seam, LED back light, high brightness for development and application of new technology, such as product will be more mature; Finally, the diversification of product size, impact for liquid crystal Mosaic products high-end market, share control with traditional display DLP products market laid a solid foundation, also to meet the emerging markets such as security, commercial display.

In the size of commonly used, is the use of 40 and 60 inches most hot, this two size is quite promising in future development, as the industry application of refinement, display manufacturers start from single product provider gradually integrated strong solution provider to the transformation. Excuse me, in the future market development, the role positioning of liquid crystal Mosaic manufacturer will happen, whether will be the stronger, the strong and the weak to survive? With integrated solutions ahead of the competition ability of enterprise. With the application of refinement, the customer’s requirements is no longer a general product solutions, more incline to combine business efficiency improvement and function realization of application solutions, so that the business level, different growing industries.

LCD splicing diversified product size of driving the development of the LCD splicing screen market, and with the emergence of this size diversity, manufacturers began to sew products, ultra narrow edge design, liquid crystal splicing product flexibility, makes the market more and more hot. DDW is specialized in the supply of liquid crystal splicing screen products businesses, both in size and very mature technology. At the same time, the size of the LCD splicing of diversified development also brings to the DDW unlimited space for development.

Time the stitching direction, the market should be standardized

    Liquid crystal splicing screen is the development with the continuous innovation of technology, make its development. Technology development, market demand is more and more big, this also attracted many display manufacturer. Numerous manufacturers into little also not of traditional LCD splicing vendors, including love go the traditional route display more stitching. In such cases, it is easy to form the polarization phenomenon. Many people only see LCD splicing high-speed development and prospects, the good side but ignore the behind its rapid development. Joining together the market in full swing cause the LCD market, in the form of two sides.

No rules no fangyuan, do anything to have rules, with the continuous development of the market, will also have a series of problems. Any industry will be a series of problems, reason is the lack of an industry standard and specifications. Specification of this industry could be adverse to the general industry users. The manufacturers can only go step by step to fumble, to practice, gradually understand the shape of the market. Summarizes a set of scientific standards in line with the industry development. So in a short period of time, the LCD splicing market may be in a chaotic pattern.

Liquid crystal splicing market constantly, will also continue to attract the major manufacturers to join. Due to the LCD splicing entry threshold low, manufacturers easily join LCD splicing. Caused a variety of situations. Also, also can appear a lot of bad products and fake products, in this case, not only damage the interests of customers, will also influence the development of liquid crystal Mosaic market.

So, with the continuous development of domestic splicing market, standardize the market will be. In order to better future, the great strength of the manufacturer should set up a business alliance, the hope is that all the power of together worked out a set of healthy development of industry standards. But due to time issues and the particularity of    LCD splicing screen market, make it hard for the market to specification. But still want a multitude of LCD splicing manufacturers don’t give up, together to create a good market atmosphere. DDW in LCD splicing industry for many years, always adhere to the line of standardized to provide customers with quality products. If the specification in the future market, DDW also will to cooperate, create LCD splicing market environment.

Liquid crystal splicing screen the new direction of users

    Fast, with the development of the DDW LCD splicing screen is made up of ordinary black and white monitor evolution, relative to the black and white monitor, LCD splicing screen color more clearly, not only pixels higher, better stability and longer service life. LCD splicing screen can be single use consists of dozens of sets of LCD splicing screen splicing, a comprehensive use of course by combination of LCD liquid crystal splicing screen splicing splicing wall must be used in the security system of large. In order to meet the needs of users, the LCD splicing screen going Gao Qinghua, intelligent and networked.

With the development of the society, the safety of users of DDW LCD splicing screen is becoming more and more high, therefore, the liquid crystal splicing screen to get a high speed development, at present, the LCD splicing screen has been widely used in the transportation sector, financial, commercial exhibition, the exhibition, radio and television, entertainment, business, government units and other places, and with the ascension of the LCD splicing technology, falling prices, more and more small businesses also have the ability to inherit the LCD splicing screen price, began to build their own monitoring system, to achieve security requirements.

The LCD splicing screen

DDW LCD splicing time the rapid development of the main factors

1, as a special screen splicing display device, liquid crystal splicing screen installation and debugging is often is a relatively tedious process and important link. Relative to the DLP and other heavy display device, light the LCD splicing screen display device is an important advantage, can greatly reduce maintenance costs.

2, LCD splicing system has struck, high resolution, can open the window display at the same time multiplex signals, a window to roam and characteristics of the overlay, can provide users with flexible and vivid pictures showed.

3, any combination, and flexible freedom. LCD splicing screen combination has a great deal of space, the small screen LCD splicing unit used as a whole screen, also can do a single screen LCD splicing can also be a pair of M * N full screen, the screen size can also be mixed assembly.

4, long life, low cost, mature technology, the service life of up to 60000 hours, guarantee system for a long time continuous work.

5, liquid crystal splicing screen seam width narrowing, lower cost will continue to expand the low-end users.

As domestic LCD splicing screen gradually improve, people’s living standards rising, home users demand for security is gradually increased, in the next few years, many LCD splicing screen manufacturers take a bigger share of priority, technology innovation and providing the humanized service, after all, nobody will like poor quality, after-sales service is bad LCD splicing screen manufacturers.

Because the LCD video monitoring system on security, crime prevention have the effect of cannot be underestimated, as the LCD splicing screen prices lower, the rising of the people’s living standard, individual users to the growing demand for home security will lead to the development of liquid crystal splicing screen. Home users will become the LCD splicing screen in emerging markets, and is expected to show significant growth in the next few years.

DDW, in view of the above problem, starts from oneself, the banner of firm product quality, adhere to technological innovation, is committed to become the industry benchmark, contribute to the development of industry. On technical innovation, the look should not be limited to their own technological innovation, but the innovation direction of cross-border, particularly with the fusion of Internet technology; On the market service, niche applications, detailed market services, to provide customers better products and services.

The LCD splicing screen space between “micro” market

Since the second half of last year, small spacing LCD splicing enterprises some hesitation. Problems are two: smaller than small spacing “micro space” the product failed to break through; According to industry’s largest independent market also failed to break through “home”. Both, was the industry’s “dream”.

Space between “micro” technology first, can meet the technical requirements of the enterprise is not much, also from a cost point of view, the cost of merchants affordability and market strength is not strong, cannot achieve “marketization”. So the development of the space between “micro” should rest instead of into the slow lane and is a better way to deal with.

Second, the LCD splicing screen household market competition is fierce, LCD splicing screen because of the market share is narrow and small spacing two limitations of the high cost of development.

For the above two problems, small spacing LCD splicing screen enterprises now have consensus: put a put the original ideas, to explore the “commercial” value.

The so-called small spacing LCD splicing screen commercial market, actually is not a “specific” type of products. But referring to do not need special customized, have bulk requirements, may be bulk supply of those applications. Look from the object, the commercial market is facing the enterprises, governments, institutions, social organizations. Look from the application types including public, conference room to display, large-scale multimedia classroom, cultural facilities, scientific and technological innovation in the field, and so on.

For the commercial market, but also the understanding of the need to have another dimension: LCD splicing screen must be found to withstand small spacing “high cost” of the market. But many areas of commercial market, just meet the effect first, the cost is more tolerant characteristic.

Because of this, you can use the following three sentences to describe small spacing commercial “outlook” : LCD splicing screen can afford a lot of advantage, there are some, competing goods is more, wars are freed, but win just messy. With contrast color television market: could afford less unknown, advantages, market competition into the open. Sta contrast, can see small spacing LCD splicing aggressively expand the commercial market, is a clever move. Commercial market will become namely after the engineering application, small spacing LCD splicing products and a strong growth.

In the face of the “direction” transformation of the industry, small spacing behind what is the nature of law? “Cost” attribute has become the key to the industry orientation.

From a technical point of view

“The effective demand of the boundary of technical evolution”, and now small spacing LCD splicing screen “technical strength” of the product, objectively determines the future competition will revolve around “cost”.

Seen from the development of the industry market

From high-end engineering, to the ordinary engineering, to the commercial, to home – this is a process of cost tolerance gradually reduce. Or, small spacing LCD splicing screen if you want to set up performance in a broader market, then you must “get warlords” on cost.

So, the cost is the key to the future development – this is the small distance between the fundamental law of the biggest LCD splicing screen industry. To find the direction, can grasp the target market. For years in a row, according to the observation of small spacing LCD splicing screen industry development experience, namely “point to the direction, is more important than climbing up the tech tree”.

DDW review: is the so-called: all roads lead to Rome. Liquid crystal splicing development direction is not one-way, but a multi-dimensional. LCD splicing enterprise also is such, although technological innovation is the fundamental industry development, however, the development of other direction is industry forward, up the development of space, do not ignore the whole forest for a tree, hanging in the technology of this tree
