Abstract

The invention provides a liquid crystal display device which comprises a liquid crystal display module, a backlight module and a bonding body, the liquid crystal display module comprises a liquid crystal display panel and a first flexible circuit board, one end of the first flexible circuit board is electrically connected to the liquid crystal display panel, and at least one first welding part isarranged at the other end of the first flexible circuit board; the backlight module comprises a plurality of light-emitting devices and a second flexible circuit board, one end of the second flexiblecircuit board is electrically connected to the light-emitting devices, at least one second welding part is arranged at the other end of the second flexible circuit board, and each second welding partis electrically connected to the corresponding first welding part in a one-to-one correspondence mode; and the bonding body is fixedly bonded to the first flexible circuit board and the second flexible circuit board so that the first welding part and the second welding part are aligned. The technical problem that alignment is inaccurate when the bonding pad in the backlight module and the bondingpad in the display module are welded is solved, and the display quality of a liquid crystal screen is improved.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to a liquid crystal display device. Background technique [0002] The display mechanism of the liquid crystal display is based on the backlight to provide white light, and through the light imaging principle of the liquid crystal display panel to obtain a colorful display picture. Among them, the backlight light source is provided by a light source in the backlight module, such as a light emitting diode, and the backlight light source is powered through the flexible circuit board in the display module to achieve the purpose of providing a light source for the liquid crystal display. [0003] At present, manufacturers usually use a thermal welding process to weld the pads of the flexible circuit board in the display module and the pads of the flexible circuit board in the backlight module together to achieve the purpose of circuit connection. However, due to the influence of the as...
