Problems solved by technology

In order to increase the transmittance of the display device, the period of the metal grid needs to be as close as possible to the period of the display pixels. Correspondingly, the frequency difference between the two will be reduced, resulting in serious moiré patterns and affecting the viewing effect of the user. , the display device's display quality is poor

Abstract

The invention provides a display device and a preparation method, and the display device comprises a substrate and a metal layer which is located on the substrate and is provided with a grid-shaped pattern, wherein the metal layer comprises a plurality of grids, and at least one part of the grids is provided with at least one projection. The visual degree of moire of the display device is reduced,and the display quality of the display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a preparation method. Background technique [0002] In the prior art, different combinations of periodic gratings are often used to achieve specific display effects. Taking a touch screen as an example, it is often necessary to superimpose a metal grid and a display array to obtain a display device with touch control and display. The metal grids are arranged periodically, and the metal grids and display pixels correspond to sine waves of different frequencies. In order to increase the transmittance of the display device, the period of the metal grid needs to be as close as possible to the period of the display pixels. Correspondingly, the frequency difference between the two will be reduced, resulting in serious moiré patterns and affecting the viewing effect of the user. , the display quality of the display device is poor.
