Why do TFT LCD screens produce bright spots, black spots, and color dots?
For LCD liquid crystal screens, for example, a TFT liquid crystal display with a resolution of 1024x768 has 786432 light point groups (one light point group is composed of three light points, which respectively control the brightness of RGB filters). The light points in each of the above light point groups are independently responsible for color display and light brightness. The bright spot phenomenon occurs on all LCD displays, including the color LCD display on digital cameras. The reason is that each light spot on the LCD screen has an independent transistor to control the strength of its current. If the transistor at that spot breaks down, it will cause the light spot to be permanently lit or not lit, and the color when lit will also fix a certain color, which is the highlight of the LCD.
