发明名称 DISPLAY HAVING A TOUCH SENSOR
摘要 The present invention provides a display device having a touch sensor. The display device comprises: a host system; a timing control unit for generating an internal data enable signal based on a data enable signal inputted from a host system, outputting a vertical synchronous signal time-dividing a first frame period into one or more display operation periods and one or more touch sensor operation periods based on the internal data enable signal, and outputting a data signal inputted from the host system; a display panel having touch sensors operated to charge a data voltage of pixels corresponding to a data signal during the display operation periods and induce touch sensing data for sensing a touch position during the touch sensor operation periods; and a touch circuit unit for operating the touch sensors during the touch sensor periods and transmitting coordinate value data in a touch position calculated through a predetermined touch recognition algorithm to the host system. The timing control unit outputs a compensation signal, according to the presence or degree of crosstalk occurring between the data signal and the touch sensing data, asynchronously from the internal data enable signal.
