The maximum power is the maximum power consumed by the LED display screen when operating at full load. Understanding the maximum power can help us choose the appropriate power supply and cooling design.
25. What is grayscale level?
Gray level refers to the degree of color depth that an LED display screen can display. The higher the grayscale level, the richer and more delicate the color expression.
26. What is refresh rate?
The refresh rate is the number of times an LED display screen updates its image per second. A high refresh rate can reduce screen flickering and ghosting, improving viewing comfort.
27. What is frame switching frequency?
The frame switching frequency is the number of times an LED display screen switches between different images per second. The higher the frame switching frequency, the smoother and more natural the dynamic image.
28. What is the temperature range?
