Embodiment Construction
[0029] In order for those skilled in the art to better understand the technical solution of the present invention, a polarizer, a touch display panel and a touch display device provided by the present invention will be described in detail below with reference to the accompanying drawings.
[0030] figure 2 A schematic cross-sectional view of a polarizer provided in Embodiment 1 of the present invention, as shown in figure 2 As shown, the polarizer includes: a polarizer main body 5 and a touch pressure detection layer 2 on the polarizer main body 5 , wherein the touch pressure detection layer 2 is used to detect the touch pressure at the touch position.
[0031] Wherein, the polarizer main body 5 in the present invention is a commonly used polarizer in existing display panels. Specifically, when the display panel is a liquid crystal display panel (Liquid Crystal Display, referred to as LCD), the polarizer body 5 is used for filtering light to adjust the display gray scale; w...

The invention discloses a polarizer, a touch display panel and a touch display device, wherein the polarizer comprises: a polarizer main body and a touch pressure detection layer located on the polarizer main body, the touch pressure detection layer is used to detect touch Touch pressure on the control position. The technical solution of the present invention uses the polarizer main body in the existing display panel as a substrate, prepares the touch pressure detection layer for realizing the touch pressure function on the polarizer main body, and passes the existing polarizer adhesion process The combination of the touch pressure detection layer and the display panel can be realized by directly adhering the polarizer with the touch pressure detection layer on the display panel. Compared with the prior art, the technical solution of the present invention does not need to provide an additional flexible substrate and optical transparent glue for the touch pressure detection layer, thereby greatly reducing the thickness of the formed touch display device, which is beneficial to touch The thinning and lightening of control display devices.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a polarizer, a touch display panel and a touch display device. Background technique [0002] figure 1 It is a schematic cross-sectional view of a touch display device with a touch pressure detection function in the prior art, as shown in figure 1 As shown, in the existing touch display device, the touch pressure detection layer 2 with pressure detection function is directly attached to the surface of the display panel 1 . Specifically, a touch pressure detection layer 2 with a pressure detection function is formed on one side of the flexible substrate 3, and then optically clear adhesive (Optically Clear Adhesive, OCA for short) 4 is provided on the other side of the substrate 3, and finally The substrate 3 with the touch pressure detection layer 2 is bonded to the display panel 1 to obtain a touch display device with a touch pressure detection function.
