Organic electroluminescent touch panel integrating touch control function, driving method for the same, and display device comprising the same
This application provides an organic electroluminescent touch panel, a driving method for the same, and a display device comprising the same. Without changing the original organic electroluminescent architecture, the cathode layer (2) of the organic electroluminescent architecture is partitioned to form a plurality of cathodes independent of and insulating from each other, the plurality of cathodes serve as touch electrodes to sense occurrence of an outside touch and transmit a touch signal to the touch display integrated chip via the lead wire, implementing that the display panel is integrated with the touch control function based on organic electroluminescent display, and by the pixel driving circuit, the control terminal of the driving module (04) is initialized in the initialization stage, threshold voltage compensation of the driving module (04) is performed in the compensation stage, which avoids an affect caused by change of the threshold voltage of the driving module (04) on lightening luminance, meanwhile, in the touch control stage, signals on the respective signal lines are all modulated in synchronization with external touch control signals sensed by the touch electrodes, the parasitic capacitance of the touch electrode can be eliminated, and touch control performance of the touch panel can be improved.
