Document Type and Number:
WIPO Patent Application WO/2019/149083
Kind Code:
A1
Abstract:
A backlight module (93), a display assembly and an electronic device (90), wherein the backlight module (93) comprises: light guide plates (13, 43, 73) that comprise a light incident surface (133) and a light emergent surface (134); light sources (15, 45, 75) that are disposed at one side of the light incident surface (133); light homogenizing elements (14, 44, 74) that are disposed on the light emergent surface (134) of the light guide plates (13, 43, 73), one end of the light homogenizing elements (14, 44, 74) close to the light incident surface (133) being located in non-display zones (140, 440); and light shading layers (16, 46, 76) that are disposed in the non-display zones (140, 440) and that are located between the light guide plates (13, 43, 73) and the light homogenizing elements (14, 44, 74). Therefore, the light may be blocked from leaking from the non-display zones (140, 440) to the outside, and the phenomenon of light leakage of the backlight module (93) may further be avoided when the width of the non-display zones (140, 440) occupied by the backlight module (93) is reduced.
