Abstract

The disclosure is directed to a display module and a manufacturing method thereof. The display module includes a display panel, a buffer structure, a fixing element, and an outer frame. The outer frame has a side frame portion and a bottom frame portion. The side frame portion and the bottom frame portion form a space. The display panel is in the space. The display panel includes a first substrate and a second substrate disposed oppositely. The first substrate has a first side surface. The second substrate has a second side surface adjacent to the first side surface. The buffer structure contacts the first side surface and the second side surface. The fixing element contacts the display panel and the outer frame. The side frame portion is between the buffer structure and the fixing element.

First claim

What is claimed is:

1. A display module, comprising:
an outer frame having a side frame portion and a bottom frame portion, wherein the side frame portion and the bottom frame portion form a space;
a display panel in the space, and comprising:
a first substrate having a first side surface; and
a second substrate having a second side surface, wherein the first substrate and the second substrate are disposed oppositely, the first side surface is adjacent to the second side surface;
a buffer structure contacting the first side surface and the second side surface;
a fixing element contacting the display panel and the outer frame, wherein the side frame portion is between the buffer structure and the fixing element;
a backlight module comprising an optical layer; and
a spacer between the backlight module and the display panel, and the spacer contacting the display panel and the optical layer of the backlight module;
wherein the spacer and the side frame portion are completely separated by an air gap.

2. The display module according to claim 1 , wherein the buffer structure comprises a coated gel and a plastic frame, the first side surface and the second side surface contact one of the coated gel and the plastic frame.

3. The display module according to claim 2 , wherein a width of the coated gel contacting the first side surface and the second side surface is smaller than or equivalent to a total height of the first substrate and the second substrate.

4. The display module according to claim 1 , wherein the fixing element is disposed outside the outer frame and contacts the display panel.

5. The display module according to claim 1 , wherein the backlight module is disposed in the space.

6. The display module according to claim 1 , wherein the spacer comprises a tape or a coated gel.

7. The display module according to claim 1 , wherein a surface of the buffer structure faces the side frame portion of the outer frame, and the surface of the buffer structure and the side frame portion of the outer frame are separated by an empty gap.

8. The display module according to claim 1 , wherein the buffer structure comprises a coated gel, the coated gel comprises an insulating material or a conductive material.

9. The display module according to claim 1 , wherein the buffer structure comprises a coated gel, the coated gel has a thickness between 0.05 mm and 0.5 mm.

10. The display module according to claim 1 , wherein the fixing element comprises a single-sided adhesive.

11. A manufacturing method of a display module, comprising:
providing a display panel comprising a first substrate and a second substrate disposed oppositely, wherein the first substrate has a first side surface, the second substrate has a second side surface adjacent to the first side surface;
disposing the display panel in an outer frame;
disposing a buffer structure to contact the first side surface and the second side surface, wherein the buffer structure comprises a coated gel;
disposing a backlight module, wherein the backlight module comprises an optical layer;
disposing a spacer between the backlight module and the display panel, wherein the spacer contacts the display panel and the optical layer of the backlight module; and disposing a fixing element outside the outer frame and contacting the display panel, wherein a side frame portion of the outer frame is between the buffer structure and the fixing element;
wherein the spacer and the side frame portion are completely separated by an air gap.

12. The manufacturing method of the display module according to claim 11 , wherein the disposing the buffer structure to contact the first side surface and the second side surface is before the disposing the display panel in the outer frame.

13. The manufacturing method of the display module according to claim 11 , wherein the disposing the buffer structure to contact the first side surface and the second side surface is after the disposing the display panel in the outer frame.

14. The manufacturing method of the display module according to claim 13 , wherein the coated gel of the buffer structure is connected between the display panel and the outer frame.

15. The manufacturing method of the display module according to claim 13 , wherein the coated gel of the buffer structure is separated from the outer frame by an empty gap.

16. The manufacturing method of the display module according to claim 15 , wherein, a surface of the coated gel faces the side frame portion, and the surface of the coated gel and the side frame portion of the outer frame are separated by an empty gap.

17. The manufacturing method of the display module according to claim 15 , wherein the outer frame has a side frame portion, a surface of the coated gel facing the side frame portion is a curved surface.

18. The manufacturing method of the display module according to claim 11 , wherein the spacer comprises a tape or another coated gel.

19. The manufacturing method of the display module according to claim 11 , wherein the fixing element comprises a single-sided adhesive.

20. The manufacturing method of the display module according to claim 11 , wherein the coated gel comprises a conductive material.
