Problems solved by technology

[0004] However, although the metal wires of the metal grid are thin, the metal wires themselves are not transparent
Therefore, when the metal grid is bonded to the display panel, the metal grid and the pixel array of the display panel will easily produce a visual effect of moire, which seriously affects the display effect of the touch display device.

Abstract

The present invention discloses a touch display device comprising a substrate, a pixel array, a light shielding pattern layer and a touch electrode layer. The pixel array comprises a plurality of pixel units. The plurality of pixel units are arranged in a first direction, and each pixel unit includes a plurality of sub-pixels. The orthographic projection of the light shielding pattern layer on the substrate is located at the junctions of the sub-pixels. The orthographic projection of the touch electrode layer on the substrate is overlapped with the plurality of pixel units. The touch electrode layer includes a grid array comprising a plurality of grid units. Each grid unit is provided with a plurality of common parts, and any two adjacent grid units are connected with one of the common part. Orthographic projections of at least two common parts of the grid units and the orthographic projection of the light shielding pattern layer on the substrate are overlapped.

Description

technical field [0001] The invention relates to touch display technology, in particular to a touch display device with grid-like touch electrodes. Background technique [0002] In recent years, in order to achieve the purposes of portability and user-friendly operation, many electronic products have used touch panels as input devices to replace traditional keyboards or mice. Among these electronic devices integrating a touch panel as an input device, a touch display device with both touch and display functions is one of the most popular products in modern times. [0003] In a traditional touch display device, a transparent metal oxide material, such as indium tin oxide (ITO), is generally used to form a touch electrode layer for touch sensing, so as to prevent the touch electrode layer from affecting the display effect. . However, indium is a rare metal, which is difficult to obtain and expensive, and thus less conducive to competition in the market. Furthermore, ITO has ...
