Abstract

Provided is a display apparatus without a front chassis or a bezel. A front frame is provided on at least one side of a display panel to hide a chip-on-film and a printed circuit board coupled to the display panel that would be otherwise exposed to the outside. A front surface of the front frame may have a color and light reflectivity corresponding to those of a non-display area of the display panel. Thus, the display panel and the front frame may appear to be integrally formed. Accordingly, a bezel-less display apparatus, in which no bezel is formed around the display panel, may be achieved.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel including a display area configured to display an image in a forward direction and a non-display area provided at edges of the display area; and
a front frame configured to cover a side of a front surface of the display panel;
wherein the front frame comprises a frame body and a plurality of layers arranged on a front surface of the frame body, the front frame having a first color corresponding to a second color of the non-display area.

2. The display apparatus according to claim 1 , wherein the non-display area comprises a black matrix region, and
wherein the plurality of layers comprise a first layer having a third color corresponding to a fourth color of the black matrix region.

3. The display apparatus according to claim 2 , wherein the plurality of layers further comprise a second layer disposed in front of the first layer and configured to decrease first light reflectivity of a front surface of the front frame such that the first light reflectivity of the front frame corresponds to second light reflectivity of the non-display area.

4. The display apparatus according to claim 3 , wherein the plurality of layers further comprise a third layer disposed between the first layer and the second layer, the third layer comprising a transparent material.

5. The display apparatus according to claim 4 , wherein the plurality of layers further comprise a fourth layer disposed between the second layer and the third layer, the fourth layer comprising an iodine (I) material.

6. The display apparatus according to claim 4 , wherein the first layer comprises an iodine (I) material.

7. The display apparatus according to claim 1 , wherein the display panel further comprises a polarizer, a first substrate disposed behind the polarizer, and a second substrate disposed behind the first substrate,
wherein a front surface of the front frame is level with a fourth front surface of the polarizer.

8. The display apparatus according to claim 7 , wherein the front frame is in contact with the first substrate.

9. The display apparatus according to claim 1 , further comprising:
a printed circuit board configured to transmit an electrical signal to the display panel; and
a chip-on-film configured to couple the printed circuit board to the display panel,
wherein the chip-on-film is disposed behind the front frame.

10. The display apparatus according to claim 9 , further comprising:
a middle mold configured to support the display panel; and
a chassis configured to be coupled to a rear side of the middle mold,
wherein the chip-on-film is bent behind the front frame toward a rear surface of the chassis.

11. The display apparatus according to claim 1 , further comprising a cover configured to cover a side surface of the display panel and a side surface of the front frame.

12. The display apparatus according to claim 11 , wherein a front surface of the cover is level with a front surface of the front frame.

13. A display apparatus comprising:
a display panel divided into a display area configured to display an image in a forward direction and a non-display area provided at edges of the display area, the display panel comprising a polarizer, a first substrate disposed behind the polarizer, and a second substrate disposed behind the first substrate; and
a front frame configured to cover at least a portion of a front surface of the display panel, the front frame having a first color corresponding to a second color of the non-display area,
wherein a front surface of the front frame is disposed on a level plane as a front surface of the polarizer.

14. The display apparatus according to claim 13 , wherein the non-display area comprises a black matrix region, and
wherein the front frame comprises a first layer having a third color corresponding to a fourth color of the black matrix region.

15. The display apparatus according to claim 14 , wherein the front frame further comprises:
a second layer disposed in front of the first layer, the second layer having a fifth color corresponding to a sixth color of the first substrate; and
a third layer disposed in front of the second layer, the third layer having a first material corresponding to a second material of the polarizer, wherein the front frame has first light reflectivity corresponding to second light reflectivity of the non-display area.

16. The display apparatus according to claim 15 , wherein the front frame further comprises a fourth layer disposed between the second layer and the third layer, the fourth layer having a seventh color corresponding to an eighth color of the polarizer.

17. The display apparatus according to claim 13 , wherein the front frame is in contact with the first substrate.

18. The display apparatus according to claim 13 , further comprises:
a printed circuit board configured to transmit an electrical signal to the display panel; and
a chip-on-film configured to connect the printed circuit board to the display panel,
wherein the chip-on-film is disposed behind the front frame to be hidden from a view from an outside of the display apparatus.

19. A display apparatus comprising:
a display panel divided into a display area configured to display an image in a forward direction and a non-display area provided at edges of the display area;
a printed circuit board;
a chip-on-film connecting the printed circuit board to the display panel;
a front frame configured to cover the chip-on-film, and disposed at a side of a front surface of the display panel; and
a cover configured to cover a side surface of the display panel and a side surface of the front frame, and arranged not to cover the non-display area.

20. The display apparatus according to claim 19 , wherein the front frame has a first color and first light reflectivity respectively corresponding to a second color and second light reflectivity of the non-display area.
