Abstract
Disclosed is an electronic device including a display layer, a sensor layer above the display layer, and a sensor driver configured to drive the sensor layer, and including a coordinate corrector configured to output a corrected sensing signal by applying an offset to a sensing signal for an input device sensed in the sensor layer, and a coordinate calculator configured to calculate coordinate information of the input device based on the corrected sensing signal, and wherein a number of negative data in the corrected sensing signal is less than a number of negative data in the sensing signal.
Claims20
An electronic device comprising:
- a display layer;
- a sensor layer above the display layer;
- and
- a sensor driver configured to drive the sensor layer, and comprising:
- a coordinate corrector configured to output a corrected sensing signal by applying an offset to a sensing signal for an input device sensed in the sensor layer;
- and
- a coordinate calculator configured to calculate coordinate information of the input device based on the corrected sensing signal, and
- wherein a number of negative data in the corrected sensing signal is less than a number of negative data in the sensing signal.
A method for driving an electronic device, the method comprising:
- receiving a sensing signal from a sensor layer based on a current induced by an input device;
- providing the sensing signal to a sensor driver;
- outputting a corrected sensing signal by applying an offset to the sensing signal;
- and
- calculating coordinate information based on the corrected sensing signal,
- wherein a number of negative data distributed in the corrected sensing signal is less than a number of negative data distributed in the sensing signal.
