Abstract

A display device comprises a display panel, a carrying member, a plurality of circuit connecting boards, a control circuit board and at least a front frame member. The carrying member carries the display panel. The circuit connecting boards are disposed adjacent to the carrying member and physically and electrically connected to the display panel. The shortest distance between the two adjacent circuit connecting boards is between 0.1 mm and 20 mm. The control circuit board is disposed adjacent to the carrying member and electrically connected to the circuit connecting boards, and electrically connected to the display panel through the circuit connecting boards. The front frame member is disposed at the outer edge of the carrying member and connected to the carrying member, and includes a turning portion and an extending portion. The thickness of the turning portion is greater than that of the extending portion.

Claims

1. A display device comprising:

a display panel;

a carrying member carrying the display panel;

a plurality of circuit connecting boards disposed adjacent to the carrying member and physically and electrically connected to the display panel, wherein the shortest distance between the two adjacent circuit connecting boards is between 0.1 mm and 20 mm;

a control circuit board disposed adjacent to the carrying member and electrically connected to the circuit connecting boards, and electrically connected to the display panel through the circuit connecting boards; and

at least a front frame member disposed at the outer edge of the carrying member and connected to the carrying member, and including a turning portion and an extending portion, wherein the thickness of the turning portion is greater than that of the extending portion.

2. The display device as recited in claim 1, wherein the shortest distance between the two adjacent circuit connecting boards is between 0.1 mm and 3 mm.

3. The display device as recited in claim 1, wherein the material of the front frame member includes aluminum, magnesium, liquid metal or alloy.

4. The display device as recited in claim 1, wherein the turning portion includes a long side and a length of the long side is between 2 mm and 50 mm.

5. The display device as recited in claim 1, wherein the front frame member covers the carrying member, the circuit connecting boards and the control circuit board, and covers a part of the display panel.

6. The display device as recited in claim 1, wherein the carrying member includes a turning portion, and the connection between the front frame member and the carrying member is adjacent to the turning portion.

7. The display device as recited in claim 1, wherein when the display device includes two or more front frame members, the front frame members are disposed on the outer edges of the display device and connected to the carrying member.

8. The display device as recited in claim 1, further comprising:

a plurality of driving ICs, wherein each of the circuit connecting boards includes a surface facing the carrying member, and the driving ICs are disposed on the surfaces and correspond to the location of the turning portion.

9. The display device as recited in claim 8, further comprising:

a heat conduction member disposed between the circuit connecting boards and the front frame member and contacting the circuit connecting boards and the turning portion, wherein the location of the heat conduction member corresponds to that of the driving IC.

10. The display device as recited in claim 1, wherein the front frame member further includes a microstructure, which is disposed on the turning portion and/or the extending portion.
