The prior art liquid crystal display has the advantages of high day quality, small size, light weight, low voltage driving, low power consumption and wide application range. Therefore, it has been widely used in small and medium-sized portable TVs, mobile phones, cameras, etc. Consumer electronics or computer products such as video recorders, notebook computers, desktop monitors, and projection televisions have gradually replaced cathode ray tubes (CRT) and become mainstream displays. In a liquid crystal display device, a lamp source of the liquid crystal display is necessary. However, the electric power system of the lamp source of the conventional liquid crystal display products is separate from the functional system of the liquid crystal display panel.

Although the soldering and pressing process of printed circuit boards is fast and convenient, it is difficult to meet the trend of miniaturization and thinness of optoelectronic products due to the rigid material of the printed circuit board, its large size, relatively high weight, and difficult deformation. It is not applicable to advanced technology products. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a liquid crystal display device to improve the power line of a conventional liquid crystal display lamp source and drive the liquid crystal display.
