Abstract

The invention discloses a touch display panel. The touch display panel comprises a display module, a linear polarizer and a composite film, wherein the linear polarizer is formed at one side of the display module; the composite film is arranged between the linear polarizer and the display module and comprises a 1 / 2 lambda wave plate, a 1 / 4 lambda wave plate, a first touch electrode layer and a second touch electrode layer; the 1 / 4 lambda wave plate is formed at the side, far from the linear polarizer, of the 1 / 2 lambda wave plate; the first touch electrode layer is formed at any side of the 1 / 4 lambda wave plate; the second touch electrode layer is formed at any side of the 1 / 2 lambda wave plate; the first touch electrode layer and the second touch electrode layer are insulated from each other. The touch display panel has the beneficial effects that touch film layers are internally arranged between the linear polarizer and the display module and are respectively bonded and fixed with the 1 / 2 lambda wave plate and the 1 / 4 lambda wave plate to form the integrated composite film, so that the lamination thickness of the panel is reduced, thus increasing the bending resistance and optical transmittance of the panel, meeting the lightening and thinning requirements of products and being applicable to flexible display panels.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display panel. Background technique [0002] As a special computer peripheral, the touch screen can provide a human-computer interaction interface between the electronic system and the user, and has been widely used in many fields, for example, in mobile phones, personal digital assistants (Personal Digital Assistant, PDA), games machine, liquid crystal display (Liquid Crystal Display, LCD), plasma display (Plasma Display Panel, PDP), etc. [0003] The structure of the existing touch display panel mostly adopts a relatively mature scheme of adding a touch film layer (ITO). Such as figure 1 As shown, the touch display panel includes a display component 110, a polarizer 120, a touch film layer 130 and a glass cover 140, wherein the display component 110, the polarizer 120, the touch film 130 and the glass cover 140 are stacked in sequence set up. figure 1 The sho...
