摘要： The present disclosure relates to an optical film configured on a top of a light guide plate. The optical film is made of quantum dot (QD) material, and the optical film is filled with a plurality of diffusion particles configured to uniformly distribute incident light toward different angles. As such, the backlight emitted from the backlight module may be uniform and may be emitted toward different angles, the color difference and the chromaticity of the display device from different viewing angles may be the same, and the performance of the display device may be improved.

摘要： The present invention provides a method for detection of in-panel mura based on Hough transform and Gaussian function fitting, including: S1. acquiring an original gray-scale image; S2. acquiring a binarized image according to the gray-scale image; S3. performing an edge detection via Hough transform to crop edges of the gray-scale image; and S4. performing histogram statistics on the cropped gray-scale image, fitting the histogram to a Gaussian function, and detecting an in-panel mura result according to the fitting parameters. The present invention is able to determine images of the display region via Hough transform in order to acquire the region for in-panel mura detection, and also evaluate severity of in-panel mura via parameters acquired by Gaussian function fitting, and thus to quickly detecting in-panel mura.

摘要： Disclosed are a display panel and manufacturing method thereof and a display device. The display panel includes a first substrate, a second substrate, a chip on film, and a shading array layer. The end of the first substrate extending beyond the second substrate forms a bonding end and the chip on film is bonded onto inner side of the bonding end. The inner surface of the first substrate is provided with metal signal wires located in non-pixel area. The shading array layer is located in the non-pixel area and completely shades the wires. Because the first substrate faces the viewer and the chip on film is bonded onto the inner side of bonding end, a bezel-less design is attained. The patterned shading layer forms a pattern corresponding to the metal signal wires to shade the wires for weakening lights reaching the wires and reducing reflectiveness of wires.

摘要： The disclosure discloses a liquid crystal panel packaging box with a temperature regulating function, including a box body and a temperature regulator, the box body includes an accommodating part, the temperature regulator is arranged in the accommodating part, and the temperature regulator is configured to release or absorb heat as an outside temperature changes to keep an internal temperature of the box body balanced. In the liquid crystal panel packaging box with temperature regulating function disclosed by the disclosure, by disposing a temperature regulator on the periphery of the box body, when the outside temperature changes, the temperature regulator may spontaneously absorb heat or release heat to regulate the temperature inside the box body, thereby reducing the temperature difference between the inside and outside the box and preventing the water vapor in the air from condensing inside the box.
