A touch control display reinforcement structure, comprising a display screen, a glass cover plate, a light tube, a light filter strip, and a printed circuit board; the light tube is disposed at the side of the glass cover plate and is horizontally or vertically displaced on the printed circuit board; the light filter strip is disposed on the light-emitting surface of the light tube; the printed circuit board is disposed at the side of the display screen, said printed circuit board being a stacked type, and the edge of the glass panel being disposed on a stack of the printed circuit board; the printed circuit board is provided with an auxiliary circuit and a light tube drive circuit, the auxiliary circuit and the light tube drive circuit are electrically connected, and the light tube is fixed to the printed circuit board and is electrically connected to the auxiliary circuit. The printed circuit board used to support and drive the light tube being a stacked type reduces the width of the edge of the liquid crystal display device and the area of the liquid crystal display device, and resolves the problem of scrapping the entire printed circuit board due to the printed circuit board corresponding to the light tube and the printed circuit board corresponding to the chip detaching during re-working of the display device. The manufacturing process of the entire product is thus reduced, such that the product assembly is more convenient and efficient. |
