Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] refer to figure 2 , the embodiment of the present invention provides a display device, including: a first display panel 10 and a second display panel 20; the first display panel 10 is arranged on the second display panel 20;

[0044] Wherein, a grating layer 30 is disposed between the first display panel 10 and the second display panel 20 to block light emitted from the first display panel 10 with an outgoing angle greater than a preset angle. ...

Abstract

The invention discloses a display device. The display device comprises a first display panel and a second display panel, the first display panel is arranged on the second display panel, a grating layer is arranged between the first display panel and the second display panel so as to block light rays emitted from the first display panel, and the emergent angle of the light rays is larger than a preset angle. According to the display device provided by the embodiment of the invention, the grating layer is arranged between the first display substrate and the second display substrate, so that theproblem of ghosting of the display device with a double-layer display panel during display can be avoided, meanwhile, the problem of halo caused by an existing ghosting removing mode is also avoided,and the display quality of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] refer to figure 1 , a double-layer display device is a two-layer display panel bonding structure, usually because there is a gap layer of 1mm-1.3mm between the main display panel (main cell) and the sub-display panel (sub cell), so there will be a corresponding main display panel The pixel A of the panel and the pixel B of the sub-display panel do not overlap at a certain viewing angle O, and then the problem of ghosting occurs. [0003] In order to solve the above ghosting problem, the commonly used method is to blur the surrounding pixels of the sub-display panel through the algorithm of local dimming, so that the display range of the white picture of the sub-display panel is larger than the image display range of the main display panel. Although this method solves the problem of ghosting to a certain extent, it will pr...
