یکنواختی صفحه نمایش کریستال مایع tft چیست:
1. The specific manifestations of the unevenness of the tft liquid crystal display:
Generally, the uneven display of the TFT LCD will be reflected in the display effect, the local display brightness is higher, and the local display brightness is darker, there is a significant difference between brightness and darkness, and even some uneven TFT LCD displays can cause backlight leakage and other phenomena. The uneven brightness of the TFT LCD screen is a common quality problem. The general user using the uneven brightness of the TFT LCD screen will be more prone to fatigue, and the display effect is not good, generally in a specific white or black screen. More obvious.
2. How to judge the uniformity of tft liquid crystal display:
The uniformity of the tft liquid crystal display can be known by measurement, and then the uniformity can be obtained through the calculation formula of the uniformity of the average brightness distribution. It is not directly judged by the naked eye because there may be deviations. The editor will use the formula here Tell everyone: the uniformity of the tft liquid crystal display = minimum brightness ÷ maximum brightness 100 percent . The higher the uniformity value of the tft liquid crystal display, the better the uniformity of the tft liquid crystal display.
