Abstract

A liquid crystal module includes a liquid crystal glass, plastic frames, a front frame, and a COF base film is disclosed. Connecting pins of the COF base film closely connects to a first end of the liquid crystal glass. The plastic frames cover a rim of the liquid crystal glass. The front frame abuts against the plastic frames arranged on two opposite surfaces of the liquid crystal glass to fasten the liquid crystal glass. Wherein the liquid crystal module further includes a positioning member causes the COF base film to bend toward a predetermined direction. At least one end of the positioning member is fixed between the front frame and the plastic frame by the front frame. A liquid crystal device includes the above-mentioned liquid crystal module is also disclosed. The liquid crystal module prevents the COF base film from being stripped off or harmed so as to enhance the non-defective rate and reduce the manufacturing cost.

Claims

1. A liquid crystal module, comprising:

a liquid crystal glass, plastic frames, a front frame, and a COF base film, connecting pins of the COF base film closely connects to a first end of the liquid crystal glass, the plastic frames cover a rim of the liquid crystal glass, the front frame abuts against the plastic frames arranged on two opposite surfaces of the liquid crystal glass to fasten the liquid crystal glass; and

wherein the liquid crystal module further comprises a positioning member causing the COF base film to bend toward a predetermined direction, and at least one end of the positioning member is fixed between the front frame and the plastic frame by the front frame;

after the COF base film is bent, a second end of the COF base film is at a distance from the positioning member or from the plastic frames.

2. The liquid crystal module as claimed in claim 1, wherein the positioning member is an L-shaped sheet made by plastic or metallic material, and a width of the positioning member is less than 0.3 mm.

3. A liquid crystal module, comprising:

a liquid crystal glass, plastic frames, a front frame, and a COF base film, connecting pins of the COF base film closely connects to a first end of the liquid crystal glass, the plastic frames cover a rim of the liquid crystal glass, the front frame abuts against the plastic frames arranged on two opposite surfaces of the liquid crystal glass to fasten the liquid crystal glass; and

wherein the liquid crystal module further comprises a positioning member causing the COF base film to bend toward a predetermined direction, and at least one end of the positioning member is fixed between the front frame and the plastic frame by the front frame.

4. The liquid crystal module as claimed in claim 3, wherein an L-shaped holding cavity is defined in an internal side of the positioning member.

5. The liquid crystal module as claimed in claim 4, wherein the positioning member causes a first end of the COF base film connecting to the first end of the liquid crystal glass to bend such that the COF base film is received in the holding cavity.

6. The liquid crystal module as claimed in claim 5, wherein a shape of the front frame is the same with that of the positioning member, and an internal wall of the front frame abuts against the positioning member.

7. The liquid crystal module as claimed in claim 6, wherein a width of the positioning member is less than or equal to the width of the COF base film.

8. The liquid crystal module as claimed in claim 6, wherein a width of the positioning member is less than 0.3 mm.

9. The liquid crystal module as claimed in claim 6, wherein the positioning member is an L-shaped sheet made by plastic or metallic material.

10. The liquid crystal module as claimed in claim 9, wherein the positioning member comprises a horizontal sheet and a vertical sheet connected to the horizontal sheet, after the COF base film is bent, the first end and the second end of the COF base film are respectively parallel to the horizontal sheet and the vertical sheet of the positioning member.

11. The liquid crystal module as claimed in claim 5, wherein after the COF base film is bent, at least the second end of the COF base film is at a distance from the positioning member or the plastic frames.

12. A liquid crystal display, comprising:

a liquid crystal module comprising a liquid crystal glass, plastic frames, a front frame, and a COF base film, connecting pins of the COF base film closely connects to a first end of the liquid crystal glass, the plastic frames covers a rim of the liquid crystal glass, the front frame abuts against the plastic frames arranged on two opposite surfaces of the liquid crystal glass to fasten the liquid crystal glass; and

wherein the liquid crystal module further comprises a positioning member for bending the COF base film toward a predetermined direction, and at least one end of the positioning member is fixed between the front frame and the plastic frame by the front frame.

13. The liquid crystal display as claimed in claim 12, wherein an L-shaped holding cavity is defined in an internal side of the positioning member.

14. The liquid crystal display as claimed in claim 13, wherein the positioning member causes a first end of the COF base film connecting to the first end of the liquid crystal glass to bend such that the COF base film is received in the holding cavity.

15. The liquid crystal display as claimed in claim 14, wherein a shape of the front frame is the same with that of the positioning member, and an internal wall of the front frame abuts against the positioning member.

16. The liquid crystal display as claimed in claim 15, wherein a width of the positioning member is less than or equal to the width of the COF base film.

17. The liquid crystal display as claimed in claim 15, wherein a width of the positioning member is less than 0.3 mm.

18. The liquid crystal display as claimed in claim 15, wherein the positioning member is an L-shaped sheet made by plastic or metallic material.

19. The liquid crystal display as claimed in claim 18, wherein the positioning member comprises a horizontal sheet and a vertical sheet connected to the horizontal sheet, after the COF base film is bent, the first end and the second end of the COF base film are respectively parallel to the horizontal sheet and the vertical sheet of the positioning member.

20. The liquid crystal display as claimed in claim 15, wherein after the COF base film is bent, at least the second end of the COF base film is at a distance from the positioning member or the plastic frames.
