Driving circuit for driving an electronic paper with black and white data voltages |
摘要 |
A driving circuit for driving electronic paper is provided, which includes a plurality of driving units. Each driving unit couples to display units of a row of the electronic paper through a data terminal for driving a display unit from a previous gray level to a target gray level during a driving period. Each driving unit includes a data driver and a switch. The data driver respectively provides a black data DC voltage and a white data DC voltage to the data terminal during a black phase and a white phase of the driving period, and provides a first pulse and a second pulse to the data node during a program phase of the driving period. The switch conducts the data node to a middle voltage between the first pulse and the second pulse. |
