Abstract
Pixel structure, driving method thereof and display device are disclosed. The pixel structure includes: light-emitting device having first electrode coupled to corresponding first voltage line. Driving chip includes: receiving circuit configured to decode first digital clock signal on first control line in display phase to obtain first address data and light emission data; address storage circuit configured to store reference address data before the display phase; data processing circuit configured to output PWM signal and current control signal corresponding to each light-emitting device according to the light emission data when the first address data is the same as the reference address data; current output circuit configured to output driving current according to the current control signal; and gating circuit configured to sequentially receive the PWM signal corresponding to each light-emitting device and transmit the driving current to the output terminal when the PWM signal is in active-level state.
