Knowledge about the uniformity of LCD display

<p>The brightness uniformity of the <a href="https://www.genyulcm.com/" rel="noopener noreferrer" target="_blank">LCD display</a> is an important indicator for judging the quality of the LCD display screen. If the uniformity is not good, it means that the backlight light source design of the LCD display screen is not good, and light leakage is prone to occur. Therefore, a good screen must have good uniformity. Next, Genyu&nbsp;will introduce to you the knowledge points about the uniformity of LCD display.</p><p><br></p><p>The brightness of the LCD display is uneven, and when reflected on the LCD display, it will cause the screen to have a large difference in brightness and darkness. Our eyeballs consume more energy than usual when dealing with this difference in brightness and darkness. Therefore, we are not using the brightness The eyes are particularly prone to fatigue when the LCD display is uniform.</p><p><br></p><p>The calculation method of the uniformity of the average brightness distribution of the surface light source is: minimum brightness ÷ maximum brightness × 100% = uniformity (data). Generally, internal inspections add 5% to customer requirements. Generally, small and medium-sized LCDs measure the brightness of 9 points, and dividing the measured minimum by the maximum is the uniformity of the 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.</p><p><br></p><p><br></p>
