Abstract

An electronic device with touch display is disclosed. The electronic device includes a host, a main display apparatus and a touchable display apparatus. The main display apparatus is connected with the host via a joint structure which is able to make the main display apparatus and the host fold against each other and the display apparatus rotate on the host. The touchable display apparatus is installed on the host. When the display function of the touchable display apparatus is disabled, the touchable display apparatus can be used as a touch pad for the host; when the display function of the touch display apparatus is enabled, the touch display apparatus displays the same contents as the display apparatus.

Claims

1. An electronic device with touch display, comprising:

a host outputting video data;

a main display apparatus displaying an image according to the video data;

a joint structure connecting the host and the main display apparatus so that the main display is rotated relative to the host; and

a touchable display apparatus electrically connected to the host and displaying the same image with the main display apparatus.

2. The electronic device with touch display as claimed in claim 1, wherein the electronic device is a tablet personal computer (tablet PC), a personal digital assistant (PDA) or a mobile phone.

3. The electronic device with touch display as claimed in claim 1, further comprising a control button for operating in coordination with the touchable display apparatus to control a cursor shown in the image.

4. The electronic device with touch display as claimed in claim 1, further comprising a switch for controlling whether the touchable display apparatus displays the image or does not display the image.

5. A tablet personal computer (tablet PC) with touch display, comprising:

a host outputting video data;

a main display apparatus displaying an image according to the video data;

a joint structure connecting the host and the main display apparatus so that the main display is rotated relative to the host; and

a touchable display apparatus electrically connected to the host and displaying the same image with the main display apparatus,

wherein the touchable display apparatus displays the image when the rotated angle of the main display apparatus reaches a predetermined angle.

6. The tablet PC with touch display as claimed in claim 5, further comprising a control button for operating in coordination with the touchable display apparatus to control a cursor shown in the image.

7. The tablet PC with touch display as claimed in claim 5, further comprising a switch for controlling whether the touchable display apparatus displays the image or does not display the image.

8. The tablet PC with touch display as claimed in claim 7, wherein the switch disables the display function of the touchable display apparatus when the main display apparatus and the host are folded against each other.
