The brightness uniformity of 2.4-inch LCD screen is an important index to judge the quality of the display screen. If the uniformity is not good, it indicates that the backlight of the LCD screen is not well designed and is prone to light leakage. Therefore, a good screen must have good uniformity. Next, Yuhua micro technology editor will introduce you to the knowledge points about the uniformity of LCD display.
The brightness of LCD screen is uneven, which will lead to large light and shade difference on the LCD screen. Our eyes will consume more energy than usual when dealing with this light and shade difference. In this way, our eyes will be prone to fatigue when using LCD screen with uneven brightness.
The brightness of the light source is calculated by the average brightness of the light source surface × 100% = uniformity (data). Generally, the internal inspection shall add 5% to the customer's requirements. Generally, small and medium-sized LCD measures the brightness of 9 points. Dividing the measured minimum value by the maximum value is the uniformity of LCD. The higher the uniformity, the better the consistency of LCD image quality. The ideal uniformity is 100%. The higher the uniformity, the better the brightness consistency of the picture.
