“Ghost Detection†will play a checkerboard screen. The screen will stay for a period of time. During this time, we do not need to stare at the screen. After waiting for the play to finish, we only need to pay attention to whether there is still image residue of the checkerboard. The smaller the number of afterimages, the better the TV dynamic response.
In "Color Detection", we need to pay attention to the smoothness of the colors in the picture, and the smoother it means that the display colors are more abundant.
"Grayscale Test" will play some grayscale squares with numbers, in which we have to choose the largest number and the smallest number that can be seen clearly.
"Bad point detection": Bad point is also called point absence. It refers to the sub-pixel points displayed on the LCD screen in black and white and red, yellow and blue. The worst fear of LCD is the bad point. Once a bad spot appears, a point on the display will always show the same color regardless of the image displayed on the display. This "bad point" is impossible to repair, and only the replacement of the entire display can solve the problem. Therefore, the detection of dead pixels is very necessary.
Xiao Bian summed up the above is a small series for everyone to organize Changhong new TV inspection leak method. It is a necessary way for the new TVs to start self-checking when they want to see assistants detect TV dead pixels, grayscale, color, afterimages, and light leakage. In order to avoid failures in the future, please do not neglect the self-inspection of new TV.
