Abstract

A display apparatus includes a bottom chassis, a display panel provided in front of the bottom chassis, and a cover film configured to cover the display panel and being fixable to the bottom chassis. With this configuration, a bezel may be minimized (e.g., reduced in size) or eliminated, and the display efficiency may be improved.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel;
a bottom chassis provided behind the display panel; and
a single transparent cover film configured to entirely cover a front surface of the display panel, the single transparent cover film configured to be fixable to the bottom chassis via a screw which extends through a hole in the bottom chassis,
wherein the bottom chassis comprises a chassis body positioned behind the display panel, and a chassis rim formed along a periphery of at least one portion of the chassis body and bent forward from the chassis body,
wherein the single transparent cover film comprises a cover portion configured to entirely cover a front surface of the display panel, and a support portion integrally extending from the cover portion and bent backward from the cover portion to face the chassis rim.

2. The display apparatus according to claim 1 , wherein the single transparent cover film is integrally formed with the display panel.

3. The display apparatus according to claim 1 , further comprising an optical module comprising a light source positioned between the bottom chassis and the display panel and configured to supply light to the display panel,
wherein the single transparent cover film is configured to be fixable to the bottom chassis to allow the display panel to be in tight contact with the optical module.

4. The display apparatus according to claim 1 , wherein the support portion is configured to be bendable from the cover portion of the single transparent cover film.

5. The display apparatus according to claim 1 , wherein the cover portion of the single transparent cover film is configured to cover the entire front surface of the display panel.

6. The display apparatus according to claim 1 , further comprising a side plate fixed to the support portion of the single transparent cover film, the side plate configured to be engaged with the chassis rim to allow the support portion to be fixed to the chassis rim.

7. The display apparatus according to claim 6 , wherein the side plate comprises: a plate body fixed to the support portion of the single transparent cover film; and
a plate engaging portion extending from the plate body and configured to be in contact with the chassis rim, the plate engaging portion being convex toward the chassis rim from the plate body to allow the plate body to be spaced apart from the chassis rim by a predetermined distance.

8. The display apparatus according to claim 7 , further comprising: a source printed circuit board (PCB) configured to control the display panel; and a flexible PCB connecting the display panel and the source printed circuit board,
wherein the side plate forms a space between the chassis rim and the plate body when engaged with the chassis rim to allow the flexible PCB to pass through the space.

9. The display apparatus according to claim 7 , wherein the chassis rim comprises:
a first rim corresponding to one side of a periphery of the display panel to which a flexible PCB is connected; and
a second rim corresponding to the other side of the periphery of the display panel where the flexible PCB is not connected, the second rim protruding forward from the chassis body.

10. The display apparatus according to claim 1 , wherein the single transparent cover film is fixed to the display panel by a lamination process.

11. A display apparatus comprising:
a display panel;
a backlight unit comprising a bottom chassis and an optical module comprising a light source positioned between the bottom chassis and the display panel and configured to supply light to the display panel, the bottom chassis at least partially defining a rear surface of the display apparatus, the rear surface positioned to face away from a viewer of the display apparatus; and
a single transparent cover film comprising a cover portion configured to entirely cover a front surface of the display panel and a support portion integrally extending from the cover portion and configured to be fixable to the bottom chassis via a screw which extends through a hole in the bottom chassis to allow the display panel to be in tight contact with the optical module
wherein the bottom chassis comprises a chassis body positioned behind the display panel, and a chassis rim formed along a periphery of at least one portion of the chassis body and bent forward from the chassis body,
wherein the support portion is bent backward from the cover portion to face the bottom chassis rim.

12. The display apparatus according to claim 11 , further comprising a side plate fixed to the support portion of the single transparent cover film, the side plate configured to be engageable with the bottom chassis to allow the support portion to be fixed to the bottom chassis.

13. A display apparatus comprising:
a bottom chassis at least partially defining a rear surface of the display apparatus, the rear surface positioned to face away from a viewer of the display apparatus;
a display panel provided in front of the bottom chassis;
a single transparent cover film comprising a cover portion configured to cover the entire front surface of the display panel, and a support portion integrally extending from the cover portion, the support portion of the single transparent cover film configured to be fixable to the bottom chassis via a screw which extends through a hole in the bottom chassis; and
a side plate provided on the support portion and detachably mounted on the bottom chassis,
wherein the bottom chassis comprises a chassis body and a chassis rim formed along a periphery of at least a part of the chassis body,
wherein the cover portion is integrally formed with the display panel, and
wherein the support portion is bent backward from the cover portion to face the bottom chassis rim and integrally formed with the side plate.

14. The display apparatus according to claim 13 , wherein the side plate comprises a plate body integrally formed with the support portion; and
a plate engaging portion extending from the plate body to be in contact with the bottom chassis, the plate engaging portion being convex toward the bottom chassis from the plate body to allow the plate body to be spaced apart from the bottom chassis.

15. The display apparatus according to claim 14 , further comprising: a source printed circuit board (PCB) configured to control the display panel; and a flexible PCB configured to connect the display panel and the source printed circuit board,
wherein the side plate forms a space between the bottom chassis and the plate body to allow the flexible PCB to passes through the space.

16. The display apparatus according to claim 15 , the chassis rim comprises a first rim corresponding to one side of the periphery of the display panel to which the flexible PCB is connected and a second rim corresponding to the other side of the periphery of the display panel where the flexible PCB is not connected, the second rim protruding forward from the chassis body.
