It is the damage caused by cutting. Some are black and some are white.

Turn the monitor to pure black, and you can see the bright spots.

Conversely, look at the dark spots.

Of course, when it is pure white, there will also be red or colored dead pixels of the color.

There are two kinds of bad pixels.

1 Frequent highlights.

2 Constant black spots.

Detect Constant Bright Spots: Turn the screen to full black, and carefully observe for 10 seconds to detect whether the screen has constant bright spots.

Detect normal black spots: Adjust the screen to full white, or all yellow, or in short, light colors. Observe carefully for 10 seconds to detect whether there are constant black spots on the screen.

You know that a screen is made up of pixels one by one, and a dead pixel is when a beam of light can't hit a certain point on the screen.

The best way to do this is to use software, which is much less eye-catching and much more accurate.

It's just that there are bad pixels.

The background of the screen can be adjusted to all black, and it is easy to see the dead pixels.

It's a dead pixel. For non-extinguishing defects (i.e., bright spots), no white or green light spots are allowed in LCD TV Area A, and at most 1 red, blue or other color light spots are allowed. A maximum of two bright spots are allowed in the entire screen, but no two or more white or green dots are allowed in any area of the screen that is 1 9 screen high and 1 9 screen width at the same time.

No matter what kind of image the LCD screen displays, these pixels will always display the same color. These faulty pixels cannot be repaired and can only be solved by replacing the entire LCD panel. These faulty pixels are usually divided into two categories, where the "dark spot" is the "black dot" that cannot be displayed no matter how the screen display image changes, and the more annoying is the "bright spot" that always emits light as long as the camera is turned on.

Dead pixels are pure black dots on a white screen or pure white dots on a black screen. This dot is always in the same position and is always a pure black or pure white dot when switching to the red, green, and blue display mode. In this case, the three subpixels of the pixel, R, G, and B are damaged, and such pixels are called dead pixels.

The r, g, and b (red, green, and blue) dots that are presented with a black screen are called bright spots.

The appearance of bright spots is divided into two cases:

In the case of a black screen, the point of simply rendering the color of R or G or B is rendered.

Red dot under a black screen.

When switching to red, green, and blue display mode, there are only white dots in one of the display modes in R, G, or B, and there are other dots in the other two modes, which is the case where there are two bright spots in the same pixel.

Dark Spots: In the case of a white screen, the color dots that are not simple r, g, and b are called dark spots.

The appearance of scotomas is divided into two cases:

When switching to red, green, and blue display mode, if there is only a black dot in the same display mode of R, G, or B, there is only one dark dot in the pixel.

When switching to red, green, and blue display mode, there are black dots in both display modes in R or G or B at the same position, indicating that there are two dark dots in the pixel.
