Abstract

The embodiment of the invention discloses a touch display module, its manufacturing method and display device. The touch display module includes a display panel and a touch display module attached to the display panel; the touch module is divided into a touch area with touch electrodes and a frame area with a black matrix. The module includes a base substrate, on the side of the base substrate close to the display panel, including a first shadow elimination layer and a second shadow elimination layer; wherein: the first shadow elimination layer is located between the touch electrode and the base substrate; The second shadow disappearing layer is located on the side of the touch electrode away from the base substrate; the thickness of the second shadow disappearing layer is greater than the thickness of the first shadow disappearing layer, and the thickness of the first shadow disappearing layer and the thickness of the second shadow disappearing layer meet the conditions : In the dark display mode, the color difference between the touch area and the border area is smaller than the preset value. Compared with the existing technology, it can greatly reduce the color difference between the touch area and the frame area, and improve the overall black effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display module, a manufacturing method and a display device. Background technique [0002] In the prior art, after the touch module and the display panel are attached to most touch display products, there will be obvious color difference between the touch area and the frame area. In order to improve the visual effect, it is necessary to reduce the touch area as much as possible The color difference with the border area can achieve a black effect. For an integrated (OGS, One Glass Solution) touch module, an existing solution is to change the black matrix material in the frame area, but the effect is not satisfactory. [0003] It can be seen that there is a problem of poor integral black effect in the prior art. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a touch display module, its manufacturing meth...
