Abstract: The present application provides a backlight module and a display device. The backlight module includes a back plate and a light source substrate, wherein a plurality of protrusions are provided on the back plate, and a groove is defined between the protrusions adjacent to each other; and the light source substrate is disposed on the back plate and covers the protrusion. In the present application, a light guide plate is provided in the groove to direct each light in the groove toward a side away from the back plate, thereby effectively alleviating a problem of a loss of light energy between light source substrates adjacent to each other and ensuring brightness uniformity of the display panel.

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.

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.
