Problems solved by technology

However, when the display panel is deformed under pressure, after the pressure is removed, the external air cannot quickly enter the space between the iron frame and the display panel due to the sealing structure of the light-shielding tape, so that the deformation of the display panel cannot be quickly restored to its original shape. If the deformation of the display panel is not recovered, pressing the display panel twice may cause the two presses to be misjudged as one press, resulting in a decrease in the accuracy of the pressure-sensitive touch function judgment.

Abstract

The embodiment of the invention provides a backlight module and a liquid-crystal display device and relates to the technical field of liquid-crystal display. The judging accuracy of a high-voltage sensitive touch function can be improved. The backlight module comprises a frame body and an optical part, wherein the frame body comprises a backboard and a side frame located on the periphery of the backboard, the backboard and the side frame form an accommodating space, the optical part is located in the accommodating space, the side frame comprises at least one exhausting channel formed in the side frame and communicated from the accommodating space to outside of the accommodating space, and each exhausting channel is of a bent structure.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal display device. 【Background technique】 [0002] With the development of display technology, current liquid crystal display products not only have ordinary touch functions, but also have pressure touch functions. Current liquid crystal display products usually include a display panel and a backlight module. Pressure-sensitive electrodes are arranged on the display panel. The iron frame on the backlight module serves as a reference ground for the pressure-sensitive electrodes. When the display panel is pressed, the display panel deforms. , the distance between the pressure-sensitive electrode and the reference ground becomes smaller, so that the capacitance between the pressure-sensitive electrode and the reference ground changes, and the pressure touch function can be realized by detecting the capacitance change. A certain ...
