Problems solved by technology

However, if the gap between the light guide plate and the backplane is too large, the optical uniformity and luminance will be reduced, and the phenomenon of bright bands will easily occur.
Conversely, if the gap between the light guide plate and the backplane is insufficient, the light guide plate will easily expand when heated and squeeze the backplane, causing warping and deformation

Abstract

A backplane assembly includes at least two backplane blocks and at least two fixing structures. A bending portion is formed on different sides of each back plate block, and each fixing structure includes a connecting piece and at least one elastic piece. The connecting piece is passed through two adjacent bending parts to connect the first backplane block and the second backplane block, and each elastic piece is sleeved on a connecting piece and limited between one end of the connecting piece and a bending part between.

Description

technical field [0001] The invention relates to a backboard component and a backlight module. Background technique [0002] At present, the backplane used for the backlight module is usually a one-piece structure. Therefore, considering the thermal expansion and contraction, the light guide plate will reserve a movable gap in the backplane to avoid extrusion deformation of the light guide plate due to thermal expansion. However, if the gap between the light guide plate and the backplane is too large, the optical uniformity and luminance will be reduced, and the bright band phenomenon will easily occur. On the contrary, if the gap reserved between the light guide plate and the back plate is insufficient, the light guide plate is easy to expand when heated and press the back plate to cause warping and deformation. [0003] Chinese Patent Publication No. CN102287627A discloses a surface light source device, which includes a light guide plate, two positioning groups, a light so...
