LENS, BACKLIGHT MODULE, DISPLAY DEVICE, AND METHOD FOR MANUFACTURING BACKLIGHT MODULE
Document Type and Number:
WIPO Patent Application WO/2024/066528
Kind Code:
A1
Abstract:
A lens (30), a backlight module (100), a display device, and a method for manufacturing the backlight module (100). The lens (30) comprises a light exit surface (31) and a mounting surface (32) provided opposite to the light exit surface (31). An accommodating groove (321) is formed at the center of the mounting surface (32). The accommodating groove (321) is used for accommodating at least one light-emitting chip (20). The mounting surface (32) is provided with microstructures (322), such that the mounting surface (32) of the lens (30) forms an uneven structure, thereby improving the reliability of the mounting of the lens (30), and effectively preventing an adhesive (220) from being accumulated on the surface of the light-emitting chip (20), so as to increase the light uniformity of the backlight module (100).
