Abstract

A control method is applied to a touch display system. The touch display system includes a display module, a touch module, and a programmable circuit. The programmable circuit is electrically connected between the touch module and the display module for executing the control method. The method includes: the touch module providing a first sense area; detecting whether the first sense area being touched or not; the display module displaying an boot image when the first sense area being touched; providing a second sense area after the boot image being displayed; detecting whether the second sense area being touched or not; and the display module displaying an on-screen display menu when the second sense area being touched, wherein the on-screen display menu includes a power item and a plurality of function items.

Claims

1. A control method, adapted to a touch display system, the touch display system comprising a touch module, a programmable circuit, and a display module, the touch module having a first sense area, the programmable circuit electrically connected between the touch module and the display module for executing the control method, the control method comprising steps of:

detecting whether the first sense area being touched or not;

displaying a boot image by the display module when the first sense area being touched;

generating a second sense area after the boot image being displayed;

detecting whether the second sense area being touched or not; and

displaying an on-screen display menu by the display module when the second sense area being touched, wherein the on-screen display menu comprises a power item and a plurality of function items.

2. The control method of claim 1, wherein the second sense area is generated by the touch module.

3. The control method of claim 1, further comprising a step of cutting off power source of the display module when the power item being touched.

4. The control method of claim 1, further comprising a step of starting an image adjustment action of the display module when the function items being touched.

5. The control method of claim 1, wherein the step of detecting whether first sense area being touched is determined by detecting whether the first sense area being touched for a first preset time.

6. The control method of claim 1, wherein the step of detecting whether second sense area being touched is determined by detecting whether the second sense area being touched for a second preset time.

7. The control method of claim 1, wherein the touch module is electrically connected to a host computer for transmitting data with the host computer, the control method further comprising a step, of:

starting a sleep mode by the display module when displaying the boot image by the display module and if the display module does not receive image data from the host computer.

8. The control method of claim 7, wherein the host computer comprises an operating system, the steps of providing the second sense area comprise:

providing an icon;

providing a driver; and

embedding the icon in the operating system by the driver, and displaying the icon as the second sense area by the operating system.

9. The control method of claim 7, further comprising a step of:

stopping data transmission between the touch module and the host computer when the function items being touched.

10. The control method of claim 7, further comprising steps of:

detecting the first sense area after starting the sleep mode; and

closing the display module if the first sense area is touched.

11. A touch display system, comprising:

a display module, comprising a control unit and a display panel;

a touch module, disposed on the display panel of the display module for providing a first sense area and a second sense area separately at different time; and

a programmable circuit, electrically connected between the touch module and the display module,

wherein the touch module controls the control unit of the display module by the programmable circuit to make the display module display a boot image when the first sense area is touched, and the touch module controls the control unit of the display module by the programmable circuit to make the display module display an on-screen display menu when the second sense area is touched.

12. The touch display system of claim 11, wherein the display module is used to provide power source to the touch module.

13. The touch display system of claim 11, wherein the programmable circuit has a timing mechanism for calculating the duration of the first sense area and the second sense area being touched.

14. The touch display system of claim 11, wherein the on-screen display menu comprises a power item and a plurality of function items, wherein the function items is selected from the group consisting of brightness, contrast, color, position, size, input signal format, and reset functions.

15. The touch display system of claim 11, wherein the touch module is electrically connected to a host computer for bidirectional data transmission between the touch module and the host computer, and the host computer is used to provide power source to the touch module.

16. A touch display system, comprising:

a display module, comprising a control unit and a display panel;

a touch module, disposed on the display panel of the display module for providing a sense area; and

a programmable circuit, electrically connected between the touch module and the control unit of the display module; and

a host computer, comprising an operating system, electrically connected to the touch module, the operating system comprising a sense icon,

wherein the touch module controls the control unit of the display module by the programmable circuit to make the display module display a boot image when the sense area is touched, and the touch module controls the control unit of the display module by the programmable circuit to make the display module display an on-screen display menu when the sense icon is touched.

17. The touch display system of claim 16, wherein the display module and the host computer are used to provide power source to the touch module separately.

18. The touch display system of claim 16, wherein the programmable circuit has a timing mechanism for calculating the duration of the sense area and the sense icon being touched.
