Quick answer: An LED receiving card sits in each cabinet, receives video data from the sending card over network cable, and drives the LED modules in that cabinet. Key specs are pixel loading capacity, number of data groups, supported driver ICs, grayscale and refresh performance, calibration data storage and monitoring or redundancy features.
Kartu Penerimaan
Kartu penerima memproses data gambar yang masuk dan mendistribusikannya ke modul LED.
Setiap kabinet LED biasanya dilengkapi dengan setidaknya satu kartu penerima.
Mengapa Kartu Penerima Sangat Penting
Penerimaan kartu secara langsung memengaruhi:
- kinerja skala abu-abu
- laju penyegaran
- konsistensi warna
- signal synchronization
Bahkan kesalahan konfigurasi sekecil apa pun dapat menyebabkan:
- warna yang tidak normal
- gangguan penglihatan
- berkedip-kedip
- masalah pemetaan
Mengapa Sistem Fine-Pitch Membutuhkan Kinerja Penerimaan yang Lebih Baik
Dalam aplikasi seperti:
- Produksi XR
- studio siaran
- pusat komando
- ruang rapat mewah
Kinerja kartu penerima menjadi jauh lebih penting.
Hal ini disebabkan karena layar dengan jarak piksel yang rapat memerlukan:
- pemrosesan data yang lebih canggih
- latensi yang lebih rendah
- sinkronisasi yang stabil
- kontrol skala abu-abu yang lebih baik
Mengapa Sistem Cadangan Penting
Proyek-proyek besar sering kali menggunakan:
- dual receiving card backup
- lingkaran sinyal yang berlebihan
- arsitektur yang tahan kegagalan
terutama di:
- sistem stadion
- pusat komando pemerintah
- ruang pengendalian transportasi
DDW Engineer Notes: LED receiving card
Banyak upaya pemecahan masalah langsung berfokus pada penggantian modul.
Namun, masalah pemetaan sinyal dan konfigurasi kartu penerima sering kali menjadi penyebab sebenarnya di balik perilaku tampilan yang tidak normal.
Key Receiving Card Specifications

|---|---|
| Pixel loading | Max pixels per card (must cover the cabinet) |
| Data groups | Number of module data outputs |
| Driver IC support | Compatibility with high-refresh ICs |
| Grayscale / refresh | Image smoothness and camera performance |
| Calibration storage | Keeps point-by-point correction data |
| Monitoring / backup | Status feedback and dual-card options |
FAQ
What does a receiving card do in an LED screen?
It receives data from the sending card and drives the LED modules in its cabinet with correct timing, grayscale and calibration.
Can receiving cards from different brands be mixed?
Generally no; receiving cards must match the sending card or processor system.
What happens when a receiving card fails?
The cabinet or area it controls usually goes black or shows errors until the card is replaced and configured.
