Abstract

A liquid crystal display. The liquid crystal display comprises a liquid crystal panel, a backlight module, a bezel and a light-inductive adhesive layer. The backlight module and the bezel are disposed respectively on the two surfaces of the liquid crystal panel so that the liquid crystal panel and the backlight module are enclosed by the bezel. The light-inductive adhesive layer is disposed between the liquid crystal panel and the bezel to adhere the bezel to the liquid crystal panel. When light of a specific wavelength irradiates the light-inductive adhesive layer, the light-inductive adhesive layer loses adhesion, enabling separation of the liquid crystal panel and the bezel.

Claims

1. A liquid crystal display, comprising:

a liquid crystal panel comprising two surfaces;

a backlight module positioned at a first of the surfaces of the liquid crystal panel;

a bezel disposed at a second of the surfaces of the liquid crystal panel, enclosing the liquid crystal panel and the backlight module; and

a light-inductive adhesive layer disposed between and adhering the liquid crystal panel and the bezel, wherein, when the light-inductive adhesive layer is irradiated by light of a specific wavelength, adhesion thereof is reduced, enabling separation of the liquid crystal panel and the bezel.

2. The liquid crystal display as claimed in claim 1, wherein the specific wavelength of the light is ultraviolet.

3. The liquid crystal display as claimed in claim 2, wherein the backlight module comprises an ultraviolet resist layer pervious to visible light and opaque to ultraviolet light.

4. The liquid crystal display as claimed in claim 1, wherein the light-inductive adhesive layer comprises an ultraviolet inductive adhesive tape.

5. The liquid crystal display as claimed in claim 1, wherein the backlight module is an edge type backlight module.

6. The liquid crystal display as claimed in claim 1, wherein the backlight module is a direct type backlight module.

7. The liquid crystal display as claimed in claim 1, wherein the backlight module is adhered to the liquid crystal panel with another light-inductive adhesive layer.

8. A liquid crystal display, comprising:

a liquid crystal panel comprising two surfaces;

a backlight module positioned at a first of the surfaces of the liquid crystal panel, the backlight module comprising an ultraviolet resisting layer pervious to visible light and opaque to ultraviolet light;

a bezel disposed at a second of the surfaces of the liquid crystal panel, enclosing the liquid crystal panel and the backlight module;

a first ultraviolet inductive adhesive layer disposed between the liquid crystal panel and the bezel to adhere the bezel to the liquid crystal panel; and

a second ultraviolet inductive adhesive layer disposed between the liquid crystal panel and the backlight module to adhere the backlight module to the liquid crystal panel;

wherein, when the first ultraviolet inductive adhesive layer and the second ultraviolet inductive adhesive layer are irradiate by ultraviolet light, adhesion thereof is reduced, enabling separation of the liquid crystal panel, the bezel and the backlight module.

9. The liquid crystal display as claimed in claim 8, wherein the first ultraviolet inductive adhesive layer and the second ultraviolet inductive adhesive layer respectively comprise an ultraviolet inductive adhesive tape.

10. The liquid crystal display as claimed in claim 8, wherein the backlight module is an edge type backlight module.

11. The liquid crystal display as claimed in claim 8, wherein the backlight module is a direct backlight module.
