Abstract

A touch-control structure for a flexible display device is provided. The touch-control structure comprises a flexible display panel, at least one menu display area, a touch film and at least one sensing element. The flexible display panel comprises a visible surface. The menu display area is located on at least one side of the visible surface. The touch film comprises a first flexible substrate and an operating contact surface. The visible surface and the operating contact surface are disposed on the two opposite ends of the touch structure respectively. The sensing element is disposed on at least one side of the first flexible substrate corresponding to the menu display area.

Claims (16)

1. A touch-control structure for a flexible display device, comprising:

a flexible display panel having a visible surface;

at least one menu display area being located on at least one side of the visible surface; and

a touch film having a first flexible substrate and an operating contact surface and comprising at least one sensing element being disposed on the operating contact surface corresponding to the at least one menu display area, wherein the visible surface and the operating contact surface are disposed on two opposite ends of the touch structure respectively, wherein a clamping force applied to the menu display area on one side of the visible surface and at the same time to the sensing element on the operating contact surface of the flexible display causes the sensing element to generate a touching signal.

2. The touch-control structure as claimed in claim 1 , wherein at least one side of the first flexible substrate is the operating contact surface.

3. The touch-control structure as claimed in claim 1 , wherein the touch film further comprises:

a second flexible substrate being configured to form a space with the first flexible substrate;

wherein at least one side of the second flexible substrate is the operating contact surface, and the at least one sensing element is disposed inside the space.

4. The touch-control structure as claimed in claim 3 , further comprising:

at least one flexible printed circuit; and

at least one metal conducting line, disposed inside the space, being configured to connect the at least one sensing element and the at least one flexible printed circuit.

5. The touch-control structure as claimed in claim 4 , wherein the at least one sensing element generates a signal according to a touch, and the at least one metal conducting line is configured to transmit the signal to the at least one flexible printed circuit.

6. The touch-control structure as claimed in claim 1 , wherein the at least one sensing element is a force sensor.

7. The touch-control structure as claimed in claim 1 , wherein the at least one sensing element is a force sensing resistor.

8. The touch-control structure as claimed in claim 1 , wherein the flexible display panel is a front plane laminate.

9. The touch-control structure as claimed in claim 1 , wherein the flexible display panel is an electrowetting display.
