Abstract: A display panel disposes a first display area and a second display area. The display panel includes a plurality of OLED pixel units disposed in the first display area, and a plurality of Micro LED pixel units disposed in the second display area. By replacing the OLED pixel units corresponding to the under-screen camera or used to display a fixed picture with the Micro LED pixel units, the image quality of an under-screen camera can be improved, and the burning screen problem caused by displaying the same picture for a long time can be solved.

Abstract: The present invention provides a backlight module and a display device. The present invention splices a substrate on a reflection plate. The reflection layer can effectively replace the reflection plate in function because of a high reflectivity of the reflection layer on the spliced portion between the substrate and the reflection plate, which guarantees extension of light and lowers requirement for assembling precision.
