The touch panel 110 may be disposed above or below the display panel 120. For example, a mutual capacitance type touch panel may be used. 2 is a schematic view for explaining the touch panel and the touch integrated circuit shown in FIG.

Referring to FIG. 2, the touch panel 110 may include a plurality of driving lines 112 and sensing lines 114 perpendicular to the driving lines 112. The sensing lines 114 may be disposed on the driving lines 112 and an insulating layer may be disposed between the driving lines 112 and the sensing lines 114 .

The touch integrated circuit 130 includes a touch driver 132 that provides driving signals to the driving lines 112 of the touch panel 110 and a touch driver 132 that generates driving signals from the sensing lines 114 of the touch panel 110 A signal processor 134 for receiving electrical signals or sensing signals and converting the electrical signals into digital signals and a controller 136 for transmitting commands to the application processor 140 according to the digital signals can do.

According to an embodiment of the present invention, the smart device 100 may execute a low power mode to reduce power consumption, and the display panel 120 may be turned off in the low power mode.

Particularly, the low power mode can be executed even while a sound source reproduction program such as a music player is being executed.

When the gesture by the user is input through the touch panel 110 while the low power mode of the display panel 120 is being performed, the smart device 100 may execute an event corresponding to the inputted gesture . In particular, when the display panel 120 is switched to the low power mode in order to reduce the power consumption of the smart device 100, the touch panel 110 may be switched to the partial scan mode. Also, when the event is executed, it is desirable that the low power mode of the display panel 120 and the partial scan mode of the touch panel 110 are continuously maintained to reduce power consumption.

FIGS. 3 and 4 are schematic diagrams for explaining the partial scan mode of the touch panel, and FIG. 5 is a schematic diagram for explaining the full scan mode of the touch panel.

3 and 4, the partial scan mode of the touch panel 110 may be performed while the display panel 120 is operated in the low power mode. That is, the partial scan mode of the touch panel 110 may be used to detect the gesture while the display panel 120 is kept off.

According to an embodiment of the present invention, driving signals may be provided to the driving lines 112 to detect the gesture while the partial scanning mode is executed, and odd-numbered or even-numbered The sensing signals corresponding to the driving signals may be received from the first sensing lines 114A or 114B.

For example, the first scan data constituting the first frame sequentially supplies driving signals to the driving lines 112 as shown in FIG. 3, and sequentially supplies driving signals to the sensing Signals. 3, the first scan data may include sensing signals S1, S3, S5, and S7 obtained from the odd-numbered sensing lines 114A after providing the first driving signal D1. S3, S5, and S7, and a third driving signal D3 obtained from the odd sensing lines 114A after providing the first driving signal D2, the second driving signal D2, The sensing signals S1, S3, S5 and S7 obtained from the odd sensing lines 114A and the fourth driving signal D4 are supplied to the odd sensing lines 114A, S3, S5, and S7 obtained from the odd-numbered sensing lines 114A after providing the fifth drive signals D5, S1, S3, S5, and S7, S3, S5, and S7 and seventh driving signals D7 obtained from the odd sensing lines 114A after providing the odd sensing lines D6, 114A S3, S5, and S7 obtained from the odd-numbered sensing lines 114A after providing the obtained sensing signals S1, S3, S5, and S7 and the eighth driving signal D8, ).

The control unit 136 may repeatedly obtain the first scan data and the second scan data to detect the gesture.

As described above, since each of the frames is constituted by the sensing signals received from the odd-numbered or even-numbered sensing lines 114A or 114B after the driving signals are provided to the driving lines 112, the touch panel 110 Can be greatly reduced. Particularly, even when the event is executed, the display panel 120 can be kept in the off state, so that the power consumption of the smart device 100 can be sufficiently reduced.

When the display panel 120 is turned on, the operation mode of the touch panel 110 may be switched from the partial scan mode to the full scan mode. The full scan mode may be used to improve the linearity and accuracy of the touch panel 110. 5, driving signals may be sequentially provided to the driving lines 112, and scan data may be acquired using electrical signals sensed from the sensing lines 114 .

The gesture may be input on the touch panel 110 in a state in which a conductor, for example, a user's hand is in contact with the touch panel 110, or in a state where the conductor is separated from the touch panel 110 by a predetermined distance. That is, the gesture can be input by dragging the conductor in contact or non-contact with the conductor. In the non-contact state, the gap between the conductor and the touch panel 110 may be several mm to several cm. For example, the gap between the conductor and the touch panel 110 may be about 5 mm to 5 cm.

According to another embodiment of the present invention, while the touch panel 110 is operated in the partial scan mode, the touch driver 132 selectively supplies driving signals to odd-numbered or even-numbered driving lines 112A or 112B And the signal processing unit 134 may selectively receive the sensing signals from the odd-numbered or even-numbered sensing lines 114A or 114B.
