Abstract:
The invention discloses a pixel internal compensation circuit and riving method. The pixel internal compensation circuit comprises: first TFT (T 1 ), with gate connected to third control signal (SCAN 3 ), source and drain connected to data voltage (Vdata) and first node (A); second TFT (T 2 ), with gate connected to first node (A), source and drain connected to second node (B) and high voltage power source (OVDD); third TFT (T 3 ), with gate connected to first control signal (SCAN 1 ), source and drain connected to first node (A) and reference voltage (Vref); fourth TFT (T 4 ), with gate connected to second control signal (SCAN 2 ), source and drain connected to second node (B) and initial voltage (Vini); capacitor C 1 , with two ends connected to first node (A) and second node (B); OLED, with anode connected to second node (B), and cathode connected to low voltage power source (OVSS). The invention provides a corresponding driving method. The invention uses parallel driving mode to effectively increase sensing time of threshold voltage compensation to improve compensation effect.

Claim (Index 8):
A driving method of the pixel internal compensation circuit as claimed in  claim 1 , comprising: the first control signal, the second control signal, and the third control signal having timing sequence configured for a reset phase, a sensing phase, a data write-in phase, and a light-emitting phase.
