Abstract

The present invention relates to a liquid crystal module including a panel, a backlight unit arranged at a back side of the panel, and a connection structure that connects the panel and the backlight unit. The connection structure includes a supporting surface that supports the panel, and is made of stainless steel. The present invention provides advantages that the connection structure made of stainless steel satisfies borderless needs of the liquid crystal module, and the liquid crystal module is capable of avoiding light leakage when the liquid crystal panel is in a L0 black color state of grayscale. Herein, the light leakage is caused by a deformation of the panel.

Claims

1. A liquid crystal module comprising:

a panel;

a backlight unit arranged at a back side of the panel;

a connection structure that connects the panel with the backlight unit, the connection structure has a supporting surface that supports the panel, and the connection structure is made of stainless steel and is arranged at the back side of the panel, and an adhesive layer is arranged between the supporting surface and the panel, the connection structure comprises;

a supporting portion that supports the panel, the supporting surface is arranged on the supporting portion; and

a connection portion that is connected with the backlight unit, wherein a threaded hole is formed in the connection portion, and a bolt is inserted through the threaded hole so that the connection structure is fixed to a back plate of the backlight unit; and

a bolt covering portion that covers a head portion of the bolt, the bolt covering portion is arranged between a back shell and the back plate.

2. The liquid crystal module according to claim 1, wherein:

the connection structure comprises a stepped portion having a first step surface and a second step surface;

the first step surface is formed by an external side surface of the supporting portion and the second step surface is formed by an external side surface of the connection portion; and

the bolt covering portion comprises;

a first portion arranged on the second step surface, an external surface of the first portion being arranged on a same plane with the first step surface; and

a second portion fixed between the back shell and the back plate.

3. The liquid crystal module according to claim 2, wherein the second portion extends from the first portion in a direction away from the panel, and then is bent with respect to the first direction and is parallel to the panel.

4. The liquid crystal module according to claim 1, wherein a positioning structure for positioning the connection structure is arranged on the back plate of the backlight unit.

5. The liquid crystal module according to claim 1, wherein the adhesive layer is provided by a double-sided tape.

6. The liquid crystal module according to claim 1, wherein the connection structure is provided by an integral structure.
