Abstract
Discussed is a display device and a driving method thereof. The driving method includes respectively receiving a plurality of sensing signals from a plurality of touch electrodes formed at a touch panel, determining whether there is a normal touch, by using a size of a touch region defined by the received sensing signals, and when it is determined that there is the normal touch, performing an operation of extracting touch coordinates of the touch region, or when it is determined that there is an abnormal touch, performing an operation of receiving the sensing signals without performing the operation of extracting the touch coordinates.
Claims9
A method of driving a display device, the method comprising:
- respectively receiving a plurality of sensing signals from a plurality of touch electrodes formed at a touch panel;
- determining whether there is a normal touch, by using a size of a touch region defined by the received sensing signals;
- and
- when it is determined that there is the normal touch, performing an operation of extracting touch coordinates of the touch region, and when it is determined that there is an abnormal touch, performing an operation of receiving the sensing signals without performing the operation of extracting the touch coordinates.
A display device comprising:
- a panel in which a plurality of pixels are respectively formed in a plurality of areas defined by intersections between a plurality of gate lines and a plurality of data lines;
- a touch panel in which a plurality of touch electrodes are formed;
- a driver configured to drive the panel;
- and
- a touch IC configured to analyze the sensing signals received from the touch panel to determine whether there is a normal touch, and when it is determined that there is the normal touch, perform an operation of extracting touch coordinates of a touch region defined by the sensing signals, or when it is determined that there is an abnormal touch, perform an operation of receiving the sensing signals without performing the operation of extracting the touch coordinates.
