Touch display substrate and preparation method thereof, and touch display device

Abstract

The embodiment of the invention provides a touch display substrate and a preparation method thereof. The touch display device relates to the technical field of touch display and can solve the problemthat the touch display device has a large thickness. A touch display substrate includes a substrate, a color photoresist pattern disposed on the substrate, and a black matrix pattern for spacing the color photoresist pattern. The touch layer includes a plurality of first touch electrodes arranged in order along a first direction and a plurality of second touch electrodes arranged in order along asecond direction. The touch layer includes a plurality of first touch electrodes arranged in order along a first direction and a plurality of second touch electrodes arranged in order along a second direction. Wherein the first touch electrode and the second touch electrode are arranged crosswise, and the crosswise positions are insulated from each other by the black matrix pattern. The inventionis used for reducing the thickness of the touch display device.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display substrate, a preparation method thereof, and a touch display device. Background technique [0002] At present, a touch screen panel (TSP) is an attractive new multimedia human-computer interaction device, which is mainly used in many fields, such as public information inquiry, electronic games, ordering songs and dishes or multimedia teaching, etc. [0003] However, if figure 1 As shown, the existing touch display device ( figure 1 Taking the touch display device as an organic electroluminescent display device (Organic Electro-luminescent Display, referred to as OLED) as an example), the display layer 10, the touch layer 20 and the color filter 30 (Color Filter) are all simple superimposed together. Although the effect of color and human-computer interaction is achieved, when the three are superimposed, since the first insulating layer 40 needs t...

AI Technical Summary

Problems solved by technology

Although the effect of color and human-computer interaction is achieved, when the three are superimposed, since the first insulating layer 40 needs to be arranged between the touch layer 20 and the color filter 30, and the first touch electrode 201 of the touch layer 20 The intersection with the second touch electrode 202 needs to be provided with a second insulating layer 50, and the thickness of the first insulating layer 40 and the second insulating layer 50 is about 6000 angstroms. Therefore, setting two insulating layers makes the touch display device thicker. Big

However, the larger thickness of the touch display device will lead to unsatisfactory performance of the touch display device. For example, for a flexible touch display device, the display device will not be easy to bend, and the screen will be easily broken.
