Embodiment Construction

[0069] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0070] like figure 1 As shown, the method for eliminating moire fringes in the embodiment of the present invention includes:

[0071] Step 101 , controlling the relative rotation between the shielding screen and the target black matrix of the display screen at preset angular intervals.

[0072] In the embodiment of the present invention, the relative rotation includes: keeping the target black matrix still and controlling the screen screen to rotate relative to the target black matrix; or keeping the screen screen stationary and controlling the target black matrix to rotate relative to the screen screen.

[0073] In practical applications, such as figure 2 As shown, the width of the s...

Abstract

The invention provides a moire fringe elimination method and device, and equipment, relates to the display technology field and aims to reduce the error generated in the moire fringe elimination process. The method comprises steps that a screen mesh and a target black matrix of a display screen are controlled for rotation relative to each other according to the preset angular interval; after eachrotation, overlapping grayscale images of the screen mesh and the target black matrix at any point on the display screen are collected; according to the grayscale images, intersecting angle sets of the screen mesh and the target black matrix are determined, and the intersecting angle sets include values of angles formed between each side of the screen mesh and each side of the target black matrix;a target intersecting angle set is determined from the multiple intersecting angle sets; the relative positional relationship between the screen mesh and the target black matrix is adjusted by utilizing the target intersecting angle set to eliminate moire fringes. The method is advantaged in that the error generated in the moire fringe elimination process can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method, device and equipment for eliminating moiré fringes. Background technique [0002] At present, the phenomenon of moiré fringes generally occurs in fully laminated products that are used for screen shielding. In the prior art, the moiré fringes are usually aligned by manually rotating the screen. Since this process needs to be completed manually, there are relatively large errors in the existing methods for eliminating moiré fringes. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a method, device and equipment for eliminating moiré fringes, so as to reduce errors generated during the process of eliminating moiré fringes. [0004] In order to solve the above technical problems, in the first aspect, the embodiment of the present invention provides a method for eliminating moiré fringes, in...
