Title:
AMOLED PIXEL DRIVING CIRCUIT AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/045667
Kind Code:
A1
Abstract:
An AMOLED pixel driving circuit and pixel driving method. By using a pixel driving circuit with a 5T1C structure, a threshold voltage of a driving thin film transistor (T1) is compensated in a source electrode following manner, and thus the threshold voltage of the driving thin film transistor (T1) can be effectively compensated, so that a current flowing through an organic light emitting diode (D) is unrelated to the threshold voltage of the driving thin film transistor (T1), a threshold voltage of the organic light emitting diode (D), and a negative power voltage (VSS), thereby ensuring uniform illumination brightness of the organic light emitting diode (D) and improving the image display effect.
