Abstract:
1. A driving method for an active matrix display having a plurality of transistors, common electrodes and capacitances arranged into a matrix, wherein each of the capacitances is formed between a drain of one corresponding transistor and common electrode, the method comprising the steps of: turning on the transistors in a line of the matrix; when a source of one of the turned on transistors receives a data signal of a first polarity, providing a first voltage to the corresponding common electrode; and when the source of one of the turned on transistors receives the data signal of a second polarity, providing a second voltage to the corresponding common electrode, wherein the sources of adjacent turned on transistors receive the data signals of the first and second polarity, and the first and second voltage are voltage references for the data signals of the first and second polarity, respectively, wherein one of the data signals is a digital signal having discrete voltage levels, and wherein the voltage levels are generated by at least a generator having a plurality of resistors connected in series between the first and second voltage, whereby the voltage levels are output from terminals between adjacent transistors.
