Introduction

The emergence of a vast LED display market will inevitably create a large number of enterprises. The technical differences of various LED display enterprises are still very large, so how to judge the quality of the display and choose a cost-effective LED display that suits you. We need to master the basic technical indicators of LED display.

In recent years, LED display screens have been shining brightly in various fields. The superior performance of LED display screens makes it have a good value in different scenarios in various fields. More and more people are beginning to be familiar with and use LED display screens. The emergence of a vast LED display market will inevitably create a large number of enterprises. The technical differences of various LED display enterprises are still very large, so how to judge the quality of the display and choose a cost-effective LED display that suits you. We need to master the basic technical indicators of LED display.

1. Brightness index

When purchasing an LED display, you must confirm the usage scene in advance, whether it is installed outdoors or indoors. Generally speaking, the outdoor light is strong, and the requirement for the brightness of the LED display is relatively high, which needs to be above 5000cd/m²; while the indoor light is weak , The brightness of the LED display is too bright, which will cause visual fatigue, eye fatigue and other bad experiences. The indoor scene of the LED display only needs 1800cd/m². If you understand this point, you won't buy the wrong product stupidly, which will lead to waste of money and poor user experience.

2. White balance indicator

The white balance effect is one of the important indicators of the display screen. Everyone is familiar with the term white balance, but many people do not understand the real principle. The full-color LED display lamp bead package adopts a three-in-one package, that is, one light Inside the bead is actually three lamp beads of red, green and blue integrated together. According to the principle of color mixing of the three primary colors, different colors are realized. In terms of color science, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. White balance The quality of the display is mainly determined by the control system of the display screen, and the die also affects the reducibility of the color.

3. Gray index

Grayscale is related to brightness, which refers to the gradation performance of brightness, that is, the so-called color scale or gray scale. The higher the gradation, the more sensitive the LED display screen can be displayed, and the performance of LED and chip control sensitivity is higher. High, the level of gray scale often determines the vividness of the color. Generally speaking, the higher the gray level, the richer the color displayed on the display screen, and the more gorgeous the viewing effect.

4. Flatness index

The flatness is the overall ups and downs of the screen. When touching the LED display, whether there is unevenness or not is called "flatness" in the industry. Although many people tend to ignore this point when buying, LED displays with high flatness A screen is a good screen. Generally speaking, the smaller the flatness, the smoother the screen display, the more uniform the color, and the better the viewing effect. On the contrary, the picture is easily distorted and the viewing effect is poor.

5. Refresh frequency index

The refresh rate refers to the number of times the screen is refreshed by the screen per second. Generally speaking, the higher the refresh rate of the LED display, the more stable and smooth the picture display is, while the low refresh rate will not only cause unsightly water ripples, but also the feeling of smearing and lagging. , It will also affect the eyes, cause visual fatigue, and make people feel uncomfortable. Especially for LED display devices such as playing competitive games, the refresh rate is particularly important, which directly affects the experience of the game. Therefore, when choosing, try to choose a refresh rate higher than 1000Hz. If the refresh rate is higher than 3,000Hz, it can be called a high-efficiency LED display, and the effect is better.

The above 5 points are just a simple explanation for the many characteristics of LED displays. There is no way to verify whether the LED display meets the requirements of stability, reliability or life in a short period of time, and there are certain limitations in electronic products. Contingency and probability, according to the selection and comparison of the above indicators, can give users the direction of reference, even if the manufacturer can make a guarantee, but it cannot replace the requirement. It is a business concept, a contract concept, not a technical concept. For how to correctly understand the product of such a complex system as LED display, it is still necessary to start from reality, analyze this product from the user's point of view, and guide users to correctly choose the cost-effective LED display.
