Abstract: A display module and a display device are provided. The display module includes a display panel and a compensation display assembly disposed in a frame region of the display panel. The compensation display assembly includes a viewing angle brightness adjustment layer. The viewing angle brightness adjustment layer includes an anti-peep function layer configured to adjust a brightness of the light emitted from the display function layer within a side viewing angle range of the display module after exiting from a side of the viewing angle brightness adjustment layer away from the display function layer.

Abstract: A display screen and a display device are provided. The display screen includes a display panel assembly, a light bar, and a reflective layer. The display panel assembly includes at least two display panels with a splicing gap between each two display panels. The light bar is attached to a display surface of the display panel assembly, covers the splicing gap, and has two opposite side surfaces extending along a length of the splicing gap. At least one side surface of the light bar is provided with the reflective layer to prevent black borders from appearing on the side surfaces of the light bar.

Abstract: A spliced screen and a display terminal are disclosed. In the spliced screen, a structural component is disposed on two adjacent display panels and covers a splicing gap between the two adjacent display panels. A lamp plate is disposed on a surface of the structural component. When the spliced screen displays an image, a plurality of luminescent bodies disposed on the lamp plate close to the display panels also emit light, thereby preventing black strips from appearing on the image. In the spliced screen, a viewing angle of the display panels and a viewing angle of the lamp plate are same, so that a brightness of the display panels and a brightness of the lamp plates are same when the spliced screen is viewed from a lateral side. As such, display quality is improved.

Abstract: An optical fiber laser coupler, comprising a laser input optical cable, a laser shaping and coupling device, and a multi-beam-mode energy transmission fiber (205). The multi-beam-mode energy transmission fiber (205) comprises a circular fiber core (105) and annular fiber cores (106, 107), and each annular fiber core (106, 107) is coaxial with the circular fiber core (105). A fluorine-doped layer (109) is disposed between the circular fiber core (105) and the annular fiber core (106, 107), and the fluorine-doped layer (109) is also disposed between adjacent annular fiber cores (106, 107). An adjustable collimating lens group (203) and an adjustable focusing lens group (204) of the laser shaping and coupling device can horizontally move along a direction of a laser beam in a housing of the laser shaping and coupling device.

Abstract: Provided are a COA array substrate and a display device. The array substrate is provided with a base layer, a metal layer, and a color resist layer from bottom to top. The array substrate is further provided with contact holes passing through the color resist layer and in contact with the metal layer, and the contact holes are arranged so that the alignment film droplets can be distributed when the alignment film droplets drop right onto the contact holes. Air bubbles as in the prior art are thus avoided, thereby preventing a cell gap due to accumulation of an alignment film from becoming larger. Thus, a luminance difference is avoided and the quality of the product is improved without upgrading the existing equipment. The brightness uniformity of the display device is improved by using the array substrate.

Abstract: The present disclosure provides an accumulated retrieval processing method. The method includes steps as follows: obtaining a retrieval instruction, the retrieval instruction comprising a retrieval keyword; performing retrieving according to the retrieval instruction, and displaying a corresponding retrieval result, the retrieval result including retrieval data matching with the retrieval keyword; obtaining a selected instruction for the retrieval data; adding the retrieval data selected according to the selected instruction to a preset selected display area, the preset selected display area is configured to independently display the selected retrieval data. According to the aforementioned method, the display area is used to independently display the selected retrieval data. Therefore the retrieval data selected by multiple retrieval can be displayed in the display area, thereby facilitating to summarize and process the retrieval data of the multiple retrieval.
