Abstract

The invention discloses a folding display panel and a preparation method of the folding display panel. The folding display panel comprises a first substrate; the second substrate arranged opposite tothe first substrate; a display layer arranged on the surface of one side of the first substrate; and a composite functional layer and an optical adhesive layer which are arranged between the display layer and the second substrate, wherein the composite functional layer comprises at least one protective layer and a touch electrode layer, and the touch electrode layer is arranged on the surface of one side of the protective layer. Compared with an existing folding display panel, a polarizing layer and a touch layer are integrated into the composite functional layer in the folding display panel,the touch electrode layer is arranged on the surface of the protective layer, a layer of stacked optical adhesive layer is omitted, the hardness of the upper layer of the stacked structure can be improved, the overall stacking design thickness is reduced, the bending radius can be reduced, the laminating process is reduced, and the process flow is simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a foldable display panel and a method for preparing the foldable display panel. Background technique [0002] With the release of folding mobile phones Samsung Galaxy fold and Huawei mate X, folding mobile phones have quickly become a fashion trend and entered the public's field of vision. To fold a mobile phone, it is necessary to continuously integrate the mechanism of the mobile phone and make the laminate thinner and thinner. [0003] Such as figure 1 as shown, figure 1 It is a schematic diagram of functional layers of a folding display panel in the prior art. The foldable display panel includes a back panel 101 (Back Panel, BP), a display layer 102, a first Optically Clear Adhesive (OCA) layer 103, a touch function layer 104, a polarizer function (Polarizer, POL) layer 105, The second optical glue layer 106 and the cover plate (Cover Windows) layer 107 . Wherein, the t...
