DISPLAY DEVICE WITH TOUCH PANEL FUNCTION |
摘要 |
A display device having a touch panel function includes a plurality of pixel circuits arranged in a matrix shape and sensing circuits arranged in a region between the adjacent pixel circuits for reading out a magnitude of coupling capacitance. A display driver writes a display signal in the pixel circuit every row line by driving the scanning lines and signal lines in a display operation period. A sensing driver senses a signal showing magnitude of the coupling capacitance from the sensing circuit every row line by driving the plurality of scanning lines and signal lines in a sensing operation period. The display operation period and the sensing operation period are repeated in turns. A voltage in a range used for the displaying operation is written into the signal line in a preliminary writing operation period between after the sensing operation period and before the display operation period.
