Abstract

The present invention provides a touch system and a display device, belongs to the technical field of display, and can solve the problem that misoperation is caused as an existing touch screen has a narrow frame and the edge area of the screen is easy to touch mistakenly. The touch system comprises a touch screen, a touch position analysis unit and a switch unit, wherein the touch screen comprises a center touch area and an edge touch area, and the touch position analysis unit is used for analyzing a position of a touch on the touch screen; and the switch unit is used for controlling whether a touch on the edge touch area is effective.

Claims

1. A touch system, comprising a touch screen, and further comprising a touch position analyzer and a switch, wherein the touch screen comprises a center touch area and an edge touch area,

the touch position analyzer is configured for analyzing a position of a touch on the touch screen;

the switch is configured for controlling whether a touch on the edge touch area is effective,

wherein when the switch is turned on, the touch on the edge touch area is effective, and when the switch is turned off, the touch on the edge touch area is ineffective,

and wherein the switch is configured to be turned on in a case where a position of content to be touched is in the edge touch area and turned off in a case where the position of content to be touched is in the center touch area.

2. The touch system of claim 1, wherein the touch position analyzer comprises a storage and a querizer,

the storage is stored therein position information corresponding to the center touch area and the edge touch area respectively;

the querizer is used for judging whether position information corresponding to current touched position of the touch screen belongs to the center touch area or the edge touch area.

3. The touch system of claim 1, wherein the touch screen comprises a display unit for displaying and a touch unit for sensing touch.

4. The touch system of claim 3, wherein the display unit is an LCD display panel or an OLED display panel.

5. The touch system of claim 3, wherein the touch unit is a resistive touch unit or a capacitive touch unit.

6. The touch system of claim 1, wherein the switch is arranged on a side of a frame of the touch screen.

7. The touch system of claim 1, wherein the touch screen is divided into the center touch area and the edge touch area by hardware.

8. The touch system of claim 1, wherein the touch screen is divided into the center touch area and the edge touch area under control of software.

9. A display device, comprising a touch system, wherein the touch system comprises a touch screen, and further comprises a touch position analyzer and a switch, wherein the touch screen comprises a center touch area and an edge touch area,

the touch position analyzer is configured for analyzing a position of a touch on the touch screen;

the switch is configured for controlling whether a touch on the edge touch area is effective,

wherein when the switch is turned on, the touch on the edge touch area is effective, and when the switch is turned off, the touch on the edge touch area is ineffective.

10. A display device of claim 9, wherein the touch position analyzer comprises a storage and a querizer,

the storage is stored therein position information corresponding to the center touch area and the edge touch area respectively;

the querizer is used for judging whether position information corresponding to current touched position of the touch screen belongs to the center touch area or the edge touch area.

11. A display device of claim 9, wherein the touch screen comprises a display unit for displaying and a touch unit for sensing touch.

12. A display device of claim 11, wherein the display unit is an LCD display panel or an OLED display panel.

13. A display device of claim 11, wherein the touch unit is a resistive touch unit or a capacitive touch unit.

14. A display device of claim 9, wherein the switch is arranged on a side of a frame of the touch screen.

15. A display device of claim 9, wherein the touch screen is divided into the center touch area and the edge touch area by hardware.

16. A display device of claim 9, wherein the touch screen is divided into the center touch area and the edge touch area under control of software.
