Abstract: A reflective pixel unit, a reflective display panel and a display apparatus are disclosed. The reflective pixel unit includes a substrate, a reflective plate on the substrate, and a reflective filter layer on a side of the reflective plate facing away from the substrate. The reflective filter layer is configured such that a surface of the reflective filter layer facing away from the reflective plate receives visible light and reflects a part of light having wavelengths within a specific range in the visible light, and allows another part of the light having wavelengths within the specific range to pass through the reflective filter layer to the reflective plate. The reflective plate is configured to reflect the another part of the light having wavelengths within the specific range passed through the reflective filter layer.

Abstract: A light guide assembly for a backlight module is disclosed, comprising a metal element and a light guide element which are integrated together. At least a portion of at least a side surface of the light guide element is used to receive light emitted from a light source to generate backlight, and the metal element surrounds a side surface of the light guide element that is not used to receive light from the light source. In this way, the backlight module can omit the structures such as rubber frame, backplate, and the like, while the overall mechanical strength of the backlight module can be ensured, the thickness of the backlight module can be decreased to meet the requirement on thinning of the display device, and the production and maintenance costs can be reduced.
