Problems solved by technology

However, if the local temperature of the liquid crystal display panel is too high, the service life of the liquid crystal display panel will be reduced, and even the risk of short circuit in the peripheral wiring will be caused.
[0003] Therefore, it is necessary to propose a technical solution to solve the problem that the life of the liquid crystal display panel is reduced due to the high temperature at the corner where the peripheral wiring extends to the chip-on-chip film.

Abstract

The invention provides a backlight module and a liquid crystal display device, the heat in a heating corner area of a liquid crystal display panel is diffused to the surrounding of a radiator in a cavity by passing through a plurality of first through holes with the air as a medium, and the radiator dissipates the heat, therefore, the temperature of the heating corner area of the liquid crystal display panel is reduced, and the problem that the life of the liquid crystal display device becomes short due to the high local temperature of the heating corner area is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] At present, when the COF is bound to the LCD panel to input electrical signals to the LCD panel, the peripheral traces electrically connecting the gate drive circuit (Gate On Array, GOA) and the COF pass through the LCD panel. The corner extends from the area where the gate drive circuit is disposed to the area where the COF is bound, so that the COF outputs the corresponding control signal to the gate drive circuit. Due to the limited space at the corner of the LCD panel, especially for high-resolution products such as 8K, the limited space will make it difficult to eliminate the heat generated by the peripheral wiring when the LCD panel is lit, resulting in the binding of the LCD panel to the chip-on-chip film. The temperature at the corresponding corner of the side can be as high ...
