Abstract: A middle frame and a display device are provided. The middle frame includes a lamination surface, an outside face, and an inside face. A drainage trough is disposed on the lamination surface. A diversion groove and a sealant storage tank are disposed on the outside face. A width of the drainage trough is less than a width of the diversion groove. The width of the diversion groove is less than a width of the sealant storage tank. The above-described configuration can ensure a greatest degree of lamination area, ensuring reliability of lamination, preventing sealant from flowing into a display area, and increasing yield of a display panel.

Abstract: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A light absorbing layer is arranged in the first gap between at least two adjacent light emitting elements. By arranging the light absorbing layer, the side light of the light emitting elements can be partially absorbed, thereby reducing an emission angle of the light bar.

Abstract: A verification fixture of a curved screen is disclosed. The verification fixture of the curved screen includes a support structure, a backlight module, and an adjusting module. The verification fixture of the curved screen can use the adjusting module to adjust positions of backlight blocks, thereby allowing the verification fixture of the curved screen to have curves having different target curvatures. Therefore, various backlight modules having different curvatures are not needed to assemble with display panels when performing a black screen test on the display panels.

Abstract: The present application provides a backlight module and a display device, including a light source component, a quantum dot component, and a wavelength-band-light-reflecting component being arranged in a stack. The wavelength-band-light-reflecting component reflects light emitted by the quantum dot component in a specific band range, so as to reduce full width at half maximum of the light. The present application reduces the full width at half maximum of monochromatic light by arranging the wavelength-band-light-reflecting component reflecting light in the specific band range, thereby increasing gamut of a display module.

Abstract: A method and architecture for configuring data in a power management integrated circuit (PMIC), and a display panel are disclosed. By means of the method for configuring data, the times of rewriting reading and loading module code for architectures of different models are reduced. A same configuration format is used for each reading and loading module model, facilitating porting of the storage module or the reading and loading module into different models. For different models, only the configuration information is required to be rewritten, and the reading and loading module performs corresponding actions according to the corresponding settings, facilitating the control of products.
