Abstract

A backplane, a backlight unit, a display device and an assembly method for the backlight unit. The back plate includes a main body portion having a plate-like structure, the main body portion including a first major surface and a second major surface opposite to each other; a first portion extending in a direction where the first major surfaces intersect, and a second portion extending from a side of the first portion opposite to a side connected to the main body portion toward a middle portion of the main body portion, the The second part and the main body are spaced apart from each other and overlap at least partially in the thickness direction of the main body; wherein, a hollow structure is provided on a part of the main body close to the extension part. The backlight unit adopting such a backplane can make the positioning of the LED light bar more precise and ensure the light effect.

Description

technical field [0001] The disclosure relates to a backplane, a backlight unit, a display device and an assembly method of the backlight unit. Background technique [0002] The backlight unit generally includes a backplane, a light guide plate disposed on one side of the backplane, and a light source, such as an LED light source, disposed opposite to the light guide plate. In order to improve the light efficiency of the backlight unit, for example, optical components such as a reflection sheet, a diffusion sheet, and a brightness enhancement film may be further provided. For a backplane with a U-fold structure, when assembling the backlight unit, the light bar is generally inserted into the U-fold structure from the front. Usually, the opening of the U-fold structure is small, so the assembly of the light bar is more difficult, and it is prone to inaccurate positioning or even distortion of the light bar, which affects the light effect of the light source.
