Abstract

A display device is disclosed. In one aspect, the display device includes a display panel displaying an image, a backlight assembly including a light source supplying light to the display panel, and a mold frame. The mold frame includes a quadrangular body surrounding the display panel and the backlight assembly, a support portion formed along an inner circumference of the body and supporting the display panel, and a plurality of buffer guides. The buffer guides are placed on the support portion the four corners of the mold frame. The buffer guide includes a bottom portion placed on the support portion and an impact absorbing portion formed over the bottom portion and contacting the body.

Claims

1. A display device, comprising:

a display panel configured to display an image;

a backlight assembly including a light source configured to supply light to the display panel; and

a mold frame including i) a quadrangular body surrounding the display panel and the backlight assembly, ii) a support portion formed along an inner circumference of the body and supporting the display panel, and iii) a plurality of buffer guides,

wherein the buffer guides are placed on the support portion at the corners of the mold frame, and

wherein each of the buffer guides includes i) a bottom portion placed on the support portion and ii) an impact absorbing portion formed over the bottom portion and contacting the body.

2. The display device of claim 1, wherein each of the buffer guides is formed of a soft material.

3. The display device of claim 2, wherein a lower portion of the display panel contacts each of the bottom portions wherein aside of the display panel contacts the impact absorbing portions, and wherein the side of the display panel is substantially perpendicular to the lower portion of the display panel.

4. The display device of claim 3, wherein the mold frame further includes recesses formed in the support portion at the corners of the mold frame.

5. The display device of claim 4, wherein the bottom portions are respectively placed in the recesses.

6. The display device of claim 5, wherein the height of each of the bottom portions is substantially the same as the depth of the respective recess.

7. The display device of claim 1, wherein each of the bottom portions includes first and second surfaces connected to each other to form a substantially L-shape.

8. The display device of claim 7, wherein the impact absorbing portion includes a pair of impact absorbing portions respectively formed on the first and second surfaces of the bottom portion.

9. The display device of claim 8, wherein each of the buffer guides has a plurality of grooves formed in each of the impact absorbing portions.

10. The display device of claim 9, wherein the grooves contact an inner side of the body.

11. The display device of claim 8, wherein each of the buffer guides has a plurality of openings formed in each of the impact absorbing portions and wherein the openings of each buffer guide exposes the respective bottom portion.

12. The display device of claim 8, wherein each of the impact absorbing portions includes i) a first portion contacting the bottom portion and ii) a second portion formed over the first portion and extending toward an interior of the mold frame.

13. The display device of claim 12, wherein a side of the display panel contacts the first portion of each of the impact absorbing portions wherein the upper portion of the display panel contacts the second portion of each of the impact absorbing portions, and wherein the side of the display panel is substantially perpendicular to the lower portion of the display panel.

14. The display device of claim 13, wherein each of the buffer guides has a plurality of grooves formed in the first portion of each of the impact absorbing portions.

15. The display device of claim 14, wherein each of the grooves contacts an inner side of the body.

16. The display device of claim 13, wherein each of the buffer guides has a plurality of openings formed in the first portion of each of the impact absorbing portions and wherein the openings of each buffer guide exposes the respective bottom portion.

17. The display device of claim 1, further including additional buffer guides placed between the corners of the mold frame.

18. A display device, comprising:

a display panel configured to display an image;

a mold frame supporting the display panel; and

a plurality of elastic members interposed between the display panel and the mold frame and configured to at least partially absorb an impact applied to the display panel.

19. The display device of claim 18, wherein the mold frame has a substantially quadrangular shape and wherein the elastic members comprise four sub-elastic members separated from each other and formed at the four corners of the mold frame.

20. The display device of claim 18, wherein a plurality of openings are formed in each of the elastic members.
