Abstract

The invention provides a touch display module and a touch display device and relates to the field of display technology. The touch display module comprises a display panel and a backlight module arranged oppositely; the backlight module comprises an annular frame body and an optical diaphragm; the display panel comprises a first pressure touch electrode, and the backlight module comprises a second pressure touch electrode; the touch display module also comprises annular sun-shading tape; the sun-shading tape comprises at least two first tape portions and at least one connecting portion; the first tape portions extend to bottom faces of grooves from side faces of the grooves, each connecting portion is connected with two adjacent first tape portions, and each connecting portion partially covers the side surface, away from the bottom face of the corresponding groove, of the corresponding first tape portion; and an air hole structure is formed between part of the connecting portions and the bottom faces of part of the grooves and penetrates through the annular frame body along the thickness direction of the annular frame body. In this way, air between the display panel and the backlight module can be discharged and get in quickly and effectively, recovery time of a pressure sensing signal is shortened, and pressure sensing precision is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a touch display module and a touch display device. Background technique [0002] With the development of touch display technology, the touch display device provided in the prior art can not only sense the position information of the user's touch operation, but also sense the magnitude of the touch pressure. Through the pressure touch technology, the touch display device can sense the strength of light pressure and heavy pressure, and call out different corresponding functions. The application of pressure touch touch has greatly improved the user experience. [0003] Please refer to figure 1 , figure 1 It is a schematic cross-sectional structure diagram of a touch display device provided in the prior art. The touch display device in the prior art includes a display panel 01 and a backlight module 02 , and the display panel 01 and the backlight module 02 are co...
