A novel method for driving the data signal transmission and the photo signal readout in a pixel of a display as well as the novel pixel structure corresponding thereto is provided to overcome the lightness uniformity issue of the conventional touch sensitive display resulting from the configuration of readout line. In the present invention, the exclusive readout line for signal readout is not necessary anymore, and through the well-designed configuration for the novel pixel, the data line carrying on a data signal would transmit a photo signal to be read out and processed as well.
