Title:
DISPLAY DEVICE WITH BUILT-IN TOUCH SENSOR, AND DRIVE METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2019/013119
Kind Code:
A1
Abstract:
The objective of the present invention is to implement a display device with a built-in touch sensor which has low-scale circuitry and with which accurate touch detection can be achieved even if an operating means other than a finger (for example a stylus pen) is used.
When a detection target is an operating means other than a finger (for example a stylus pen), touch detection is performed in a first scanning period with a plurality each of sensor electrodes disposed side by side in a first direction (for example a direction in which scanning signal lines extend) connected together electrically, and touch detection is performed in a second scanning period with a plurality each of the sensor electrodes disposed side by side in a second direction (for example a direction in which video signal lines extend) connected together electrically.
