BACKLIGHT MODULE, DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/259044
Kind Code:
A1
Abstract:
The present disclosure relates to a backlight module, a display panel and a display apparatus, which belong to the field of displays. The backlight module comprises: a back plate, at least one light bar and a reflector sheet, wherein the back plate comprises a bottom plate and a frame surrounding the bottom plate; the at least one light bar is fixed on an inner sidewall of the frame, and there is a gap between an end part of each light bar and the inner sidewall of the frame in the extension direction of the light bar; the reflector sheet is located in the frame and is located on the bottom plate; and at least one first sidewall of the reflector sheet is provided with at least one first protrusion, each first protrusion extends from the first sidewall, on which the first protrusion is located, towards the inner sidewall of the frame that is opposite the first sidewall, on which the first protrusion is located, and each first protrusion is located in a respective gap. When the reflector sheet moves, the first protrusion abuts against the end part of the light bar, so as to limit the movement range of the reflector sheet, thereby preventing excessive movement of the reflector sheet from reducing an area of the reflector sheet that can reflect light, ensuring the emission amount and display uniformity of the light, and enhancing the display brightness and display effect of a display panel.
