2. Panel
LCD splicing panel of good or bad directly affect the work of the product length, many businesses also put forward "no bad point", "no bright spot" commitment, in fact, the LCD panel on the non-repairable physical pixel point is the bad point, and the bad point is divided into bright spots and dark points two kinds. Highlights are pixels that still glow when the screen displays black, and dark dots that do not display the color of the pixel point. Because their presence can affect the display of the picture, the less bad points, the better. Consumers are hard to detect with the naked eye.
