Abstract

A display module with heat dissipation structure and a handheld device thereof. The display module includes a touch panel, a display panel and a vapor chamber. One face of the display panel is correspondingly attached to the touch panel, while the other face of the display panel is correspondingly attached to the vapor chamber. The vapor chamber serves to support the touch panel and the display panel. Moreover, the vapor chamber serves to absorb the heat generated by the electronic component and quickly and uniformly spread the heat to dissipate the heat to achieve a heat spreading effect.

First claim

What is claimed is:

1. A display module with heat dissipation structure, comprising:
a touch display panel including a touch panel and a display panel, the touch panel having a touch face and a bottom face opposite to the touch face, the display panel having an upper face and a lower face, the bottom face of the touch panel being connected with the upper face of the display panel, the touch panel being positioned on upper side of the display panel; and
a sealed vapor chamber comprising an upper cover and a lower cover that are closed to each other to form the vapor chamber, the vapor chamber having a first side and a second side opposite to the first side, the first side of the vapor chamber being an outer side of the upper cover and attached to the lower face of the display panel, the second side of the vapor chamber being an outer side of the lower cover.

2. The display module with heat dissipation structure as claimed in claim 1 , wherein the vapor chamber further has a vacuum chamber and at least one capillary structure, a working fluid being filled in the chamber, the capillary structure being formed on inner wall of the chamber.

3. The display module with heat dissipation structure as claimed in claim 2 , wherein the vapor chamber further has multiple support columns disposed in the chamber, upper ends of the support columns abutting against and connecting with upper inner wall of the chamber, lower ends of the support columns abutting against and connecting with lower inner wall of the chamber.

4. The display module with heat dissipation structure as claimed in claim 2 , wherein the vapor chamber has an area larger than or equal to an area of the touch display panel.

5. A handheld device comprising:
a display module including a touch display panel and a sealed vapor chamber, the touch display panel including a touch panel and a display panel, the display panel being disposed between the touch panel and the vapor chamber, the touch panel having a touch face and a bottom face opposite to the touch face, the display panel having an upper face and a lower face, the bottom face of the touch panel being attached to the upper face of the display panel, the touch panel being positioned on upper side of the display panel, the vapor chamber comprising an upper cover and a lower cover that are closed to each other to form the vapor chamber, the vapor chamber having a first side and a second side opposite to the first side, the first side of the vapor chamber being an outer side of the upper cover and attached to the lower face of the display panel, the second side of the vapor chamber being an outer side of the lower cover;
an electronic component assembly, one side of the electronic component assembly being attached to the second side of the vapor chamber; and
a frame body having a receiving space, one side of the frame body being recessed to form the receiving space for receiving the electronic component assembly and the display module, the other side of the electronic component assembly being attached to a bottom side of the receiving space.

6. The handheld device as claimed in claim 5 , wherein the electronic component assembly includes a circuit board and a battery, multiple electronic components being disposed on the circuit board and correspondingly attached to the second side of the vapor chamber, the battery being attached to the second side of the vapor chamber in adjacency to the circuit hoard.

7. The handheld device as claimed in claim 6 , wherein the vapor chamber has a vacuum chamber and at least one capillary structure, a working fluid being filled in the chamber, the capillary structure being formed on inner wall of the chamber.

8. The handheld device as claimed in claim 7 , wherein the vapor chamber further has multiple support columns disposed in the chamber, upper ends of the support columns abutting against and connecting with upper inner wall of the chamber, lower ends of the support columns abutting against and connecting with lower inner wall of the chamber.

9. The handheld device as claimed in claim 8 , wherein the frame body has a top section and a bottom section, the touch face of the touch panel being flush with the top section of the frame body.

10. The handheld device as claimed in claim 8 , wherein the vapor chamber has an area larger than or equal to an area of the touch display panel.
