Abstract

An operation method of a touch panel includes the following steps. A touch signal generated when the touch panel senses a touch is received. According to the touch signal, whether a location of the touch moves from a triggering zone to a working zone on the touch panel is determined. When the location of the touch moves to the working zone from the triggering zone, the touch panel is controlled to operate under a multi-touch mode. When the location of the touch does not move to the working zone form the triggering zone, the touch panel is controlled to operate under a mouse mode.

Claims

1. An operation method of a touch panel, comprising:

receiving a touch signal generated by the touch panel when the touch panel senses a touch;

according to the touch signal, determining whether a location of the touch moves from a triggering zone to a working zone on the touch panel;

when the location of the touch moves from the triggering zone to the working zone, controlling the touch panel to operate under a multi-touch mode; and

when the location of the touch does not move from the triggering zone to the working zone, controlling the touch panel to operate under a mouse mode.

2. The operation method of the touch panel according to claim 1, wherein, when the location of the touch moves from the triggering zone to the working zone, the step of controlling the touch panel to operate under the multi-touch mode comprises:

determining whether the location of the touch moves from the triggering zone to the working zone successively;

when the location of the touch moves from the triggering zone to the working zone successively, controlling the touch panel to operate under the multi-touch mode; and

when the location of the touch does not move from the triggering zone to the working zone successively, returning to the step of receiving the touch signal.

3. The operation method of the touch panel according to claim 2, wherein, when the location of the touch does not move from the triggering zone to the working zone successively, the operation method further comprises the following steps before the step of returning to the step of receiving the touch signal:

determining whether the touch is removed from the working zone;

when the touch is not removed from the working zone, returning to the step of determining whether the touch is removed from the working zone; and

when the touch is removed from the working zone, performing the step of returning to the step of receiving the touch signal.

4. The operation method of the touch panel according to claim 3, wherein, when the touch is removed from the working zone, the operation method further comprises the following steps before the step of returning to the step of receiving the touch signal:

determining whether a time period the touch is removed from the working zone is greater than a preset value;

when the time period is greater than the preset value, performing the step of returning to the step of receiving the touch signal; and

when the time period is not greater than the preset value, returning to the step of determining whether the time period the touch is removed from the working zone is greater than the preset value.

5. The operation method of the touch panel according to claim 1, wherein after the step of controlling the touch panel to operate under the multi-touch mode, the operation method further comprises:

determining whether the touch is removed from the working zone;

when the touch is not removed from the working zone, controlling the touch panel to continuously operate under the multi-touch mode; and

when the touch is removed from the working zone, returning to the step of receiving the touch signal.

6. The operation method of the touch panel according to claim 5, wherein, when the touch is removed from the working zone, the operation method further comprises the following steps before the step of returning to the step of receiving the touch signal:

determining whether a time period the touch is removed from the working zone is greater than a preset value;

when the time period is greater than the preset value, performing the step of returning to the step of receiving the touch signal; and

when the time period is not greater than the preset value, controlling the touch panel to continuously operate under the multi-touch mode.

7. The operation method of the touch panel according to claim 1, wherein, when the location of the touch does not move from the triggering zone to the working zone, the operation method further comprises the following steps after the step of controlling the touch panel to operate under the mouse mode:

determining whether the touch is removed from the working zone;

when the touch is not removed from the working zone, controlling the touch panel to continuously operate under the mouse mode; and

when the touch is removed from the working zone, returning to the step of receiving the touch signal.

8. The operation method of the touch panel according to claim 7, wherein, when the touch is removed from the working zone, the operation method further comprises the following steps before the step of returning to the step of receiving the touch signal:

determining whether a time period the touch is removed from the working zone is greater than a preset value;

when the time period is greater than the preset value, performing the step of returning to the step of receiving the touch signal; and

when the time period is not greater than the preset value, controlling the touch panel to continuously operate under the mouse mode.

9. The operation method of the touch panel according to claim 1, wherein, when the location of the touch does not move from the triggering zone to the working zone, the step of controlling the touch panel to operate under the mouse mode comprises:

determining whether the touch occurs by directly touching the working zone;

when the touch occurs by directly touching the working zone, controlling the touch panel to operate under the mouse mode; and

when the touch occurs by not directly touching the working zone, returning to the step of receiving the touch signal.
