Abstract

In a liquid crystal display module, notches are disposed on limiting sections and opposite to flexible circuit boards disposed on a liquid crystal panel so that the flexible circuit boards protrude through the notches and are bent toward the connecting sections; and moreover first depressed sections configured to accommodate the flexible circuit boards may be disposed on the connecting sections and opposite to the notches; and second depressed sections depressed inward may be disposed on the folded edge and opposite to the first depressed sections so that the first depressed sections and the second depressed sections cooperate with each other.

First claim

The invention claimed is:

1. A liquid crystal display module, comprising a liquid crystal panel, an adhesive frame, and a backboard, wherein the liquid crystal display module comprises:
flexible circuit boards, disposed on sides of the liquid crystal panel,
a folded edge, facing the liquid crystal panel, disposed on a periphery of the backboard and configured to fix the adhesive frame,
wherein the adhesive frame comprises carrying sections parallel to a light incidence surface of the liquid crystal display module panel, limiting sections located above the carrying sections and perpendicular to the light incidence surface of the liquid crystal display module panel, and connecting sections disposed below the carrying sections and opposite corresponding to the limiting sections,
wherein the carrying sections are configured to support the liquid crystal panel, the limiting sections are configured to limit the liquid crystal panel to move in a plane horizontal parallel to the light incidence surface of the liquid crystal display module panel, and the connecting sections are configured to cover an outside of the folded edge of the backboard, so that the adhesive frame and the backboard are fixed to each other,
wherein notches are disposed on the limiting sections and opposite corresponding to the flexible circuit boards, so that the flexible circuit boards protrude and are bent toward the connecting sections,
first depressed sections depressed inward are disposed on the connecting section and opposite corresponding to the notches to accommodate the flexible circuit boards, and
second depressed sections depressed inward are disposed on the folded edge and opposite corresponding to the first depressed sections, so that the first depressed sections and the second depressed sections cooperate with each other.

2. The liquid crystal display module according to claim 1 , wherein the liquid crystal display module further comprises optical components disposed between the backboard, and the carrying section of the adhesive frame, wherein third depressed sections depressed inward are disposed on the optical components and opposite corresponding to the second depressed sections, so that the third depressed sections cooperate with the second depressed sections.

3. The liquid crystal display module according to claim 2 , wherein distances between the third depressed sections and the second depressed sections are no less than expansion gaps between the optical components.

4. The liquid crystal display module according to claim 1 2, wherein at least one first buckle is disposed in at least one position of the connecting sections other than the first depressed section, and a second buckle corresponding to the first buckle is disposed in a position of the folded edge other than the second depressed sections, and the first buckle is engaged with the second buckle.

5. The liquid crystal display module according to claim 4 , wherein at least one first screwed hole is disposed in at least one position of the connecting sections other than the first depressed section and the first buckle, and a second screwed hole is disposed on the folded edge and opposite corresponding to the first screwed hole.

6. The liquid crystal display module according to claim 5 , further comprising a front housing comprising a front end face and a sidewall, wherein the front end face is fit onto a light exit face of the liquid crystal panel, and an inside of the sidewall is fit onto the connecting sections in positions other than the first depressed sections, and accommodation spaces to accommodate the flexible circuit boards is formed between the inside of the sidewall and the first depressed sections.

7. The liquid crystal display module according to claim 6 , wherein protecting sections are disposed on sides, of the first depressed sections of the connecting sections, away from the carrying sections, and the protecting sections are flushed with the connecting sections, and steps are formed by the protecting sections and the first depressed sections, and the steps cooperate with the front housing, so that the first depressed sections with the front housing being installed are enclosed forming closed spaces.

8. The liquid crystal display module according to claim 6 , wherein a height of the folded edge is no less than thicknesses of the optical components in the a direction perpendicular to the light incidence surface of the liquid crystal display module panel.

9. The liquid crystal display module according to claim 2 , wherein at least one first buckle is disposed in at least one position of the connecting sections other than the first depressed section. and a second buckle corresponding to the first buckle is disposed in a position of the folded edge other than the second depressed sections, and the first buckle is engaged with the second buckle.

10. The liquid crystal display module according to claim 3 , wherein at least one first buckle is disposed in at least one position of the connecting sections other than the first depressed section, and a second buckle corresponding to the first buckle is disposed in a position of the folded edge other than the second depressed sections, and the first buckle is engaged with the second buckle.

11. A display device, comprising a liquid crystal display module comprising a liquid crystal panel, an adhesive frame, and a backboard, wherein the liquid crystal display module comprises:
