LIGHT GUIDE PLATE, BACKLIGHT MODULE AND DISPLAY

摘要

A light guide plate (10) comprises a plate body (11) and multiple accommodating grooves (13). The plate body (11) comprises a light-incident side (111) and a non-light-incident side. The accommodating grooves (13) are linearly arranged on the edge of the light-incident side (111) and penetrate the plate body (11). Each accommodating groove (13) is provided with an opening (14) that communicates the accommodating groove (13) with the outside, elastic arms (15) are formed on the two sides of each opening (14), and a pushing block is arranged in a protrusive manner at a position of each elastic arm (15) facing the corresponding accommodating groove (13). Also disclosed are a backlight module and a display. The light guide plate ensures the tightness between a strip light source and the light guide plate and improves the light-incident efficiency.
