Problems solved by technology

[0004] In the prior art, the moire phenomenon is usually improved by reducing the line width of the metal line, for example, reducing the line width of the metal line to 3.5 μm, but the inventors found that when the line width of the metal line is very low, it is easy to cause Problems such as metal wire disconnection and poor antistatic ability appear

Embodiment 1

[0042] The embodiment of the present invention provides a metal grid, and when the line width of the metal lines in the metal grid is relatively large, the moiré phenomenon can be improved.

[0043] like Figure 1-Figure 4 As shown, the metal grid includes a plurality of repeating units 1, and the metal wires 2 in the repeating units 1 form at least two different patterns, and the patterns surrounded by the metal wires 2 in the repeating units 1 are arranged irregularly, so that the When the metal grid with the above structure is used as a touch electrode in a touch screen, after the touch screen is bonded to the display module, the overlapping phenomenon of the lines between the metal grid and the black matrix in the display module can be improved, and then the metal grid can When the line width of the line 2 is large, the phenomenon of moiré fringes can be improved, thereby avoiding problems such as disconnection of the metal line 2 and poor antistatic ability.

[0044] It ...

Embodiment 2

[0056] The embodiment of the present invention provides a touch screen, such as Figure 5 As shown, the touch screen includes a substrate 3 and touch electrodes 4 arranged in an array on the substrate 3 , and each touch electrode 4 includes the metal grid described in the first embodiment. It can be seen from the description in Embodiment 1 that the metal grid has a plurality of repeating units 1, and the metal wires 2 in each repeating unit 1 form at least two different patterns, and the patterns formed by the metal wires 2 in the repeating unit 1 Irregular arrangement, so that after the touch screen and the display module are bonded, the overlapping phenomenon of the lines between the metal grid and the black matrix in the display module can be improved, and then when the line width of the metal line 2 is large, that is, The phenomenon of moiré fringes can be improved, thereby avoiding problems such as disconnection of the metal wire 2 and poor antistatic ability.

Abstract

The embodiment of the invention discloses a metal grid, a touch screen and a display device, which relate to the field of display technology and can improve the moiré phenomenon when the line width of the metal line is relatively large. The metal grid includes a plurality of repeating units, the metal wires in the repeating units form at least two different patterns, and the patterns formed by the metal wires in the repeating units are arranged irregularly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a metal grid, a touch screen and a display device. Background technique [0002] In order to improve the user experience effect of the display device, a touch screen has been widely used in the display device. Specifically, the touch screen includes touch electrodes for sensing touch positions, and metal grids with low resistance are usually used as the touch electrodes to reduce resistance-capacitance delay and increase signal transmission speed of the touch electrodes. [0003] At present, the touch electrodes used in OGS touch screens are usually regular metal grids, which include a plurality of metal lines parallel to each other and arranged at equal intervals extending along the first direction, and A plurality of metal wires extending parallel to each other and arranged at equal intervals in the second crossing direction. Since the metal grid has the above structure and ...
