  LCD splicing display screenIt has the characteristics of high resolution and large viewing angle, and is widely used in urban management, environmental monitoring, security monitoring, government and enterprise information release, exhibition systems, and display devices. When there is a problem with the pixels and their color no longer changes, the phenomenon of bad pixels will occur. Today, the editor will tell you how to repair bad pixels in LCD splicing screens.

Before repairing, it is necessary to first identify whether the bad pixel phenomenon of the screen display device can be repaired. If it is a color bright spot, it means that only the pixel of this point is stuck and can be repaired. However, if the point is a black dot, it means that the pixel of this point cannot be repaired.

Marking pen squeezing method. Turn on the LCD screen and adjust it to a color that contrasts sharply with the bad pixel color, such as black or white. Then, locate the bad pixel and gently press the smooth part with a marker pen until white light appears. If it does not appear, you can slightly increase the pressing force, about 5 to 10 times, to restore the stuck pixel to normal.

Hot towel dry compress method. Soak the towel in hot water, take it out and wring it dry. Place the hot towel on the screen with bad spots to ensure heat concentration. After applying heat for ten minutes, the inside of the LCD screen will be heated and flow, and the bad spots will return to normal.
