회사 소식 How are LED displays powered and signaled?

The signal configuration for LED displays is determined by modular pixel count. For instance, with a module size of 256×128, a single signal port can drive 256×128 pixels. To calculate the capacity of a receiver card with 12 signal ports, you would multiply 12 by 256×128. However, it is crucial to consider the receiver card's maximum load capacity. Additionally, factors such as the sending card's driving capability, computer configuration, and interfaces must be taken into account. If the total pixel count exceeds 1.3 million, an external processor is likely required. This processor functions similarly to a video wall controller, allowing for more sending cards and significantly higher load capacity.

The power supply calculation for LED displays is based on maximum load capacity, measured in Watts. We assess the wattage, Amps, and Volts per line. Since LED displays operate on constant current, the primary considerations are managing voltage drop and ensuring sufficient power—essentially maintaining voltage stability while providing adequate wattage.For example, consider a screen with a total power consumption of 30 kW, divided into 32 cabinets. Given that each cable has a maximum load capacity of 2 Amps, we analyze the layout: if one cable can power 10 cabinets without exceeding 2A (equivalent to 10 kW), then the distribution system requires at least 4 output circuits to ensure proper power supply to every cabinet.
