Abstract

An electronic display module is provided. The electronic display module includes a touch display assembly, a first circuit board, and a second circuit board. The touch display assembly has a bottom edge and a top edge located at two sides of the touch display assembly. The first circuit board is connected to the bottom edge of the touch display assembly. The second circuit board is connected to the top edge of the touch display assembly. A distance from the active area to the bottom edge is different from a distance from the active area to the top edge.

Claims

1. An electronic display module, comprising:

a touch display assembly comprises;

a main substrate having an active area and a first extending area extending outward in a first direction; and

a cover substrate having a second extending area extending outward in a second direction;

a first circuit board connected to the first extending area; and

a second circuit board connected to the second extending area,

wherein the first direction is different to the second direction,

wherein the projection distance from edge of the active area to edge of the first extending area through the first direction is greater than the projection distance from edge of the active area to edge of the second extending area through the second direction.

2. The electronic display module as claimed in claim 1, wherein the touch display assembly comprises:

a plurality of transistors formed on the active area of the main substrate;

a sealing material disposed between the main substrate and the cover substrate; and

a liquid-crystal layer disposed between the main substrate and the cover substrate and adjacent to the sealing material.

3. The electronic display module as claimed in claim 1, wherein the first extending area is exposed by the cover substrate.

4. The electronic display module as claimed in claim 1, wherein the length of the first circuit board is greater than the length of the second circuit board.

5. The electronic display module as claimed in claim 1, wherein the first direction is opposite to the second direction.

6. The electronic display module as claimed in claim 1, further comprising a protection substrate, and the cover substrate disposed between the main substrate and the protection substrate.

7. The electronic display module as claimed in claim 6, further comprising a touch sensing unit disposed between the cover substrate and the protection substrate.

8. The electronic display module as claimed in claim 1, further comprising a first driving chip disposed on the main substrate and a second driving chip disposed on the second circuit board.

9. The electronic display module as claimed in claim 1, wherein the touch display assembly comprises:

a plurality of transistors formed on the active area of the main substrate;

a sealing material disposed between the main substrate and the cover substrate; and

an OLED layer disposed between the main substrate and the cover substrate and adjacent to the sealing material.

10. The electronic display module as claimed in claim 1, wherein the edge of the first extending area comprises a straight line, and the edge of the second extending area comprises a straight line.

11. The electronic display module as claimed in claim 10, wherein the straight line of the first extending area is parallel to the straight line of the second extending area.

12. The electronic display module as claimed in claim 1, wherein the active area is round shape.

13. The electronic display module as claimed in claim 1, wherein the first circuit board and the second circuit board are connected to each other at a rear of the touch display assembly.

14. The electronic display module as claimed in claim 1, further comprising a connector positioned on the first circuit board, wherein the second circuit board is connected to the first circuit board through the connector.
