Anonymous users2024-02-06What is the bad pixel of LCD display.
The bad pixel of the LCD screen is also known as the point absence, which refers to the display of the LCD screen in black and white and the three primary colors of red, yellow and blue. Sub-pixels, each of which refers to a sub-pixel.
A bright spot is a type of bad pixel. At present, there are two common LCD dead pixels: bright spots and dark pixels.
Bright spots are colored pixels that appear when the background color of the LCD screen is all black, or other color spots that appear when the background color switches between all red, all blue, and all green. Bright spots are easier to spot because they emit light that is different from other pixels. A dark spot is a dark black spot that appears when the background color of the LCD screen is completely white.
Which color is displayed on the screen, the dark dot always does not emit light and has no color, so it is not easy to be noticed. Scotomas are usually more likely to occur than bright spots. We can use test software such as DisplayX or Monitors Matter Check Screen to detect whether there are dead pixels on the LCD screen. ;
