Abstract: A shift register unit includes an input circuit, a first control circuit, a second control circuit, a third control circuit, a first output circuit, and a second output circuit. The first and second output circuits selectively transfer a first reference voltage from a first reference voltage terminal and a third reference voltage from a third reference voltage terminal to an output terminal of the shift register unit. This allows the shift register unit to output a desired output signal in an easy manner.

Abstract: The present disclosure relates to a touch panel and a touch screen. In the touch panel, the cathode is reused. In the touch control stage, each of the cathodes serves as a touch electrode, and normal display and touch functions of the touch panel can be realized by a time-division driving manner. Specifically, in the display stage, the pixel circuit controls the light emitting state of each pixel point (each pixel point has a light emitting device including a cathode); in the touch control stage, touch control signals are applied onto all control signal terminals of the pixel circuit and the cathodes at the same time. By doing so, on the basis that the touch control function can be realized, the synchronous driving of the touch control electrodes and the electrodes corresponding to the touch control electrodes can be realized.
