Abstract

A portable electronic device including a first touch display device, a second touch display device and a processing device is provided. The first touch display device is disposed on a first surface of a device body and configured to display a first image frame. The second touch display device is disposed on a second surface of the device body, configured to display a second image frame and receives a touch input. The processing device is coupled to the first touch display and the second touch display. The processing device is configured to verify gesture information of the touch input to determine whether to execute an application associated with the gesture information. The first image frame of the first touch display device correspond to the application. In addition, a method of operating the portable electronic device is also provided.

Claims

1. A portable electronic device, having a device body, comprising:

a first touch display device, disposed on a first surface of the display body and configured to display a first image frame;

a second touch display device, disposed on a second surface of the display body, configured to display a second image frame and receive a touch input, wherein the first surface is opposite to the second surface;

a processing device, coupled to the first touch display device and the second touch display device, and configured to verify gesture information of the touch input to determine whether to execute an application associated with the gesture information; and

a sensing device, coupled to the processing device and configured to sense a vertical axial parameter and an illumination parameter of the second touch display device,

wherein the first image frame of the first touch display is determined by the application,

wherein the processing device determines that the second touch display device is lying downward or lying upward according to the vertical axial parameter and the illumination parameter to respectively display the second image frame of the second touch display device as an information mode or a picture mode.

2. The portable electronic device according to claim 1, wherein the second touch display device comprises an electronic paper display panel.

3. The portable electronic device according to claim 1, wherein when the gesture information of the input touch does not pass verification, the processing device reads a gesture learning database, and further verifies whether the touch input is operable according to the gesture learning database.

4. The portable electronic device according to claim 1, further comprising:

a first touch sensing device, disposed on a third surface of the display body, coupled to the processing device, and configured to sense first touch information; and

a second touch sensing device, disposed on a fourth surface of the display body, coupled to the processing device and configured to sense second touch information, wherein the third surface is opposite to the fourth surface,

wherein the processing device determines whether to set up an unlocking request, so that the first touch display device displays a main picture or an unlocking picture.

5. The portable electronic device according to claim 4, wherein the processing device determines to execute a left-hand mode, a right-hand mode or a both-hand mode according to distribution of respective touch points of the first touch information and the second touch information.

6. The portable electronic device according to claim 4, wherein the processing device senses hand print feature information through at least one of the first touch sensing device and the second touch sensing device, and the processing device determines whether the hand print feature information conforms to default hand print feature information, so that the first touch display device displays the main picture.

7. The portable electronic device according to claim 4, wherein at least one of the first touch sensing device and the second touch sensing device is further configured to provide a force feedback according to a press force when the press force is received.

8. A method of operating a portable electronic device suitable for a portable electronic device including a first touch display device and a second touch display device, the method comprising:

receiving a touch input through the second touch display device;

verifying gesture information of the touch input to determine whether to execute an application associated with the gesture information; and

sensing a vertical axial parameter and an illumination parameter of the second touch display device through a sensing device, and determining that the second touch display device is lying downward or lying upward according to the vertical axial parameter and the illumination parameter to respectively display a second image frame of the second touch display device as an information mode or a picture mode,

wherein a first image frame of the first touch display device is determined by the application.

9. The method according to claim 8, wherein the second touch display device comprises an electronic paper display panel.

10. The method according to claim 8, further comprising:

reading a gesture learning database when the gesture information of the touch input does not pass verification, and further verifying whether the touch input is operable according to the gesture learning database.

11. The method according to claim 8, wherein the portable electronic device further comprises a first touch sensing device and a second touch sensing device, the method comprising:

sensing first touch information through the first touch sensing device and second touch information through the second touch sensing device; and

determining whether to set up an unlocking request, so that the first touch display device displays a main picture or an unlock picture.

12. The method according to claim 11, further comprising:

determining to execute a left-hand mode, a right-hand mode or a both-hand mode according to distribution of respective touch points of the first touch information and the second touch information.

13. The method according to claim 11, further comprising:

sensing hand print feature information through at least one of the first touch sensing device and the second touch sensing device; and

determining whether the hand print feature information conforms to default hand print feature information, so that the first touch display device displays the main picture.

14. The method according to claim 11, wherein at least one of the first touch sensing device and the second touch sensing device is further configured to provide a force feedback according to a press force when the press force is received.
