  • Display device including touch screen compensation and touch sensing method thereof
    Patent number: 9329725
    Abstract: A display device comprises a timing controller and a touch sensing unit. The timing controller drives a display panel such that a display mode for displaying an image in the display panel and a touch mode for sensing a user' s touch are alternately driven. The touch sensing unit differentially applies DTX (display touch crosstalk) compensation values by compensation area to sense the user' s touch in the touch mode, each of touch sensing block being a sensing unit for a user' s touch. Each compensation area is set based on a distance between a data driver and the compensation area. Each DTX compensation value is a value for compensating for an error of touch data caused by changes in respective grayscale values applied to pixels corresponding to a specific touch sensing block. The touch sensing blocks are divided in a column direction depending on arrangement of multiplexers in the data driver.

  • Touch Screen Display Device
    Publication number: 20150378508
    Abstract: A touch screen display device is discussed. The device uses common electrodes, which are formed for display images, as touch electrodes. In a display interval, the common electrodes receive a common voltage and allow images to be displayed. In a touch sensing interval corresponding to a non-display interval of a single frame of plural frames, the common electrodes are driven as the touch electrodes and allow a touch position to be sensed. When the touch sensing interval is terminated, the data voltages which had been applied to the data lines before the touch sensing interval are re-applied to the data lines. As such, when a succeeding display interval starts after the touch sensing interval, the reduction of charging voltage in a pixel can be prevented or reduced. Therefore, a picture fault or an image fault can be prevented.
