Problems solved by technology

[0004] (1) The signal drive circuit board 49 is arranged on the back side of the backlight source 43, which increases the thickness of the LCD; when the LCD is connected with other circuits, a support needs to be added on the back side of the backlight source 43, which further increases the weight and thickness of the LCD , affecting the user's perception
[0005] (2) because the signal driving circuit board 49 of existing LCD is connected with crystal box 44 by flexible circuit 45, so the LCD of the same type in the peripheral circuit all needs the signal driving circuit board 49 of different sizes, causes the increase of cost, and also As a result, it is difficult to integrate and generalize the signal driving circuit board 49 and the signal conversion circuit board, which is not conducive to reducing costs through integration
[0006] (3) When the signal drive circuit board 49 breaks down and needs to be replaced, all the flexible circuits 45 must be stripped off, glued off and reconnected, resulting in increased repair costs; if the circuit is upgraded, the liquid crystal display must be re-produced
