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.
