Abstract
An OLED print head includes a control unit and a plurality of lighting units. The control unit is configured to output a start signal and a brightness signal. Each lighting unit includes a shift register, a driving circuit and an OLED. These shift registers are connected in series so that a shift output terminal of a previous stage's shift register is coupled to a shift input terminal of a subsequent stage's shift register. An actuation output terminal of each shift register outputs an actuation output signal, and the actuation output signal has an actuation pulse wave corresponding to a time point of a trigger pulse wave. The driving circuit is configured to store a brightness voltage corresponding to the brightness signal in a driving capacitor in response to the trigger pulse wave of a scanning signal.
