ABSTRACT:
A driving apparatus of a multiple-scanning driving circuit relating to a simple pixel structure of 2T1C (2 TFTs and 1 capacitor) includes a write-scan circuit, an erase-scan circuit and a data driving circuit. A write-enable line connected to the write-scan and the data driving circuits is used to control the signals of these two circuits. One erase-enable line connected to the erase-scan and the data driving circuits is used to control the signals of these two circuits. Thus, a circuit system of time-multiplex multiple write-scan and erase-scan is completed to solve the problems of a low time utility rate and an insufficient luminance in a digital driving AMOLED system.
