Title:
BACKLIGHT MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/148967
Kind Code:
A1
Abstract:
Backlight modules (10, 20, 31) and an electronic device (30). By means of the backlight modules (10, 20, 31), when an optical assembly (12) is assembled, a first positioning portion (1213) and a second positioning portion (141) are cooperatively positioned to receive the optical assembly (12) within accommodating spaces (101, 201), such that the distance between a light guide plate (121) and a backlight source (13) is less than or equal to a threshold value, thus preventing a circumstance from occurring during assembly in which the distance between the light guide plate (121) and the backlight source (13) is excessively large, causing the light guide plate (121) to not be able to completely receive light emitted by the backlight source (13). The backlight efficiency of the light guide plate (121) is thus improved, the assembly precision may be increased and the assembly difficulty may be decreased.
