A testing method for splicing screens is provided. The method includes: outputting an image signal to a display screen, wherein the display screen includes a plurality of splicing screens, the image signal includes a plurality of testing sub pictures, the testing sub pictures are arranged correspondingly to the splicing screens so as to enable the splicing screens to display the corresponding testing sub pictures, and the testing sub pictures include testing contents; and testing the splicing screens through the testing contents, wherein the testing contents include a graduation signal, by which an accurate test is performed on the splicing screens.

Testing method for splicing screens

The present disclosure relates to a light guide plate and a fabricating method thereof, an array substrate and a fabricating method thereof, and a display device. In the light guide plate provided in the present disclosure, in a region corresponding to a first display region for arranging a gate driven circuit, more net-dots are provided or the diameter of net-dots is set to be larger, such that the luminance of outgoing light from the light guide plate in this region can be increased, thereby weakening the luminance difference between the corresponding display region and other display region.

Light guide plate and fabricating method thereof, array substrate and fabricating method thereof, and display device

A testing method and a testing apparatus for splicing screens () are provided. The method includes: outputting an image signal to a display screen, wherein the display screen includes a plurality of splicing screens (), the image signal includes a plurality of testing sub pictures, the testing sub pictures are arranged correspondingly to the splicing screens () so as to enable the splicing screens () to display the corresponding testing sub pictures, and the testing sub pictures include testing contents (); and testing the splicing screens () through the testing contents (). Testing on the splicing screens () is achieved, and a testing result can be used for regulating the splicing screens (), so that defects generated in the displaying process of the splicing screens () are reduced.

Testing method and testing apparatus for splicing screens

A light guide plate for the edge-lit backlight module comprises a first recessed portion and a second recessed portion. The first recessed portion is provided at the bottom of a light incident end of the light guide plate for accommodating a light source. The second recessed portion is provided at the top of the light incident end of the light guide plate, corresponding to the first recessed portion.

Light guide plate, backlight module and display device

The present invention is directed to a light guide plate, a backlight module and a display device with the light guide plate comprising a bottom surface containing space for holding light sources, a light emitting surface opposite the bottom surface and a quantum dot layer arranged in the containing space in the direction of the light emitting surface. Since the bottom surface of the light guide plate is provided with the containing space for holding the light sources, and the light sources are limited within the containing space, light diffusion due to the fact that the light sources are positioned outside the light guide plate is reduced, loss of light is reduced, and quantity of the light sources in the backlight module is reduced. Since the quantum dot layer is arranged in the containing space toward a direction of the light emitting surface, white mixed light is formed according to fluorescent effect of quantum dot materials. Further, as the quantum dots have the characteristics of high color gamut and high transmittance, display effect can be improved.
