TOUCH CONTROL METHOD, TOUCH CONTROL DEVICE AND DISPLAY DEVICE HAVING TOUCH DETECTION FUNCTION
First Claim
1. A touch control method of a touch control device which drives a touch sensor to collect data indicating a position of at least one object to be detected, which is located on or close to the touch sensor, and outputs the data to an external device, the touch sensor comprising plural first electrodes arranged to extend a first direction, and plural second electrodes arranged to extend in a second direction crossing the first direction in which the first electrodes extend, the touch control method comprising:
- driving the first electrodes in a self-detection mode to specify at least one of the first electrodes which detects the object; and
driving the specified at least one first electrode and the second electrodes in a partial mutual detection mode to collect data indicating the position of the object located on or close to the touch sensor.

8. A touch control device which drives a touch sensor to collect data indicating a position of at least one object to be detected, which is located on or close to the touch sensor, and outputs the data to an external device, the touch sensor comprising plural first electrodes arranged to extend in a first direction, and plural second electrodes arranged to extend in a second direction crossing the first direction in which the first electrodes extend, the touch control device comprising:
-
a controller which exerts a centralized control of the touch control device; a touch driver which is electrically connected to the first and second electrodes, applies a self-detection mode and a partial mutual detection mode to collect data indicating the position of the object on or close to the touch sensor, and outputs the data to the controller; a selector which switches, in a case of driving the first and second electrodes in the partial mutual detection mode, a signal connection to cause a drive synchronization signal from the touch driver to be supplied to one of the first electrodes which is designated by the controller; and a self switch which switches, in a case of driving the first electrodes in the self-detection mode, the signal connection to cause the first electrodes and the touch driver to be signal-connected to each other; and switches, in a case of driving the first and second electrodes in the partial mutual detection mode, the signal connection to cause a drive synchronization signal from the selector to be supplied to the one of the first electrodes. - View Dependent Claims (9)

10. A display device having a touch detection function, comprising:
-
a touch control device which drives a touch sensor to collect data indicating a position of at least one object to be detected, which is located on or close to the touch sensor, and outputs the data to an external device, the touch sensor comprising plural first electrodes arranged to extend in a first direction, and plural second electrodes arranged to extend in a second direction crossing the first direction in which the first electrodes extend; and display pixels which make a display based on an image signal and a display drive signal, wherein the touch control device comprises; a controller which exerts a centralized control of the touch control device; a touch driver which is electrically connected to the first and second electrodes, applies a self-detection mode and a partial mutual detection mode to collect data indicating the position of the object on or close to the touch sensor, and outputs the data to the controller; a selector which switches, in a case of driving the first and second electrodes in the partial mutual detection mode, a signal connection to cause a drive synchronization signal from the touch driver to be supplied to one of the first electrodes which is designated by the controller; and a self switch which switches, in a case of driving the first electrodes in the self-detection mode, the signal connection to cause the first electrodes and the touch driver to be signal-connected to each other; and switches, in a case of driving the first and second electrodes in the partial mutual detection mode, the signal connection to cause a drive synchronization signal from the selector to be supplied to the one of the first electrodes. - View Dependent Claims (11, 12, 13)
