  • Patent number: 12062649
    Abstract: A light-emitting module includes a light-emitting panel which includes a first rigid substrate, a flexible substrate, a circuit layer, a light-emitting element, and a driver chip. The flexible substrate includes a light-emitting region, a bending region, and an epitaxial region, and the light-emitting region and the epitaxial region are located on two ends of the bending region. The circuit layer includes a first connection terminal located on the epitaxial region and the driver chip is bonded to the first connection terminal. The light-emitting element is located on the light-emitting region, and the light-emitting element emits light toward the first rigid substrate. The flexible substrate is bent in the bending region and the flexible substrate in the epitaxial region is bent to a side of the light-emitting elements facing away from the first rigid substrate. The process difficulty can be reduced and the product yield can be improved.

  • Patent number: 10795075
    Abstract: Backlight module and display device are provided. The backlight module includes an accommodation frame including a base and an extending part, a first light guide plate, a second light guide plate; a first reflector, a first light source, and a second light source. The first light guide plate and the second light guide plate are disposed sequentially along a direction perpendicular to a plane of the base in an accommodation space formed by the base and the extending part, and are controlled independently. The first light source has a wavelength ?1 of 780 nm<?1?1310 nm, and the second light source has a wavelength ?2 of 380 nm??2?780 nm. A reflectivity of the first reflector on light emitted by the second light source is larger than a reflectivity of the first reflector on light emitted by the first light source.
