ABSTRACT:
An active matrix driving method for driving a display apparatus including a plurality of pixels for receiving image data, a ferroelectric member for controlling the plurality of the pixels, and a plurality of scanning signal lines and a plurality of data signal lines for driving the plurality of the pixels utilizing a memory function caused by spontaneous polarization of the ferroelectric member. The matrix driving method includes the steps of applying a reset pulse having a first polarity and a data writing pulse having a second polarity to one scanning signal line selected from the plurality of the scanning signal lines throughout a specified selection period; applying a reset pulse having the second polarity and a data pulse having the first polarity or a level of 0 to each of the plurality of the data signal lines in synchronization with the reset pulse and the data writing pulse applied to the selected scanning signal line; applying a reset compensating pulse having the second polarity and a data writing prohibiting pulse having the first polarity or a level of 0 to the selected scanning signal line throughout a period other than the specified selection period; and applying a reset pulse having the second polarity and a data pulse having the first polarity or a level of 0 to each of the plurality of the data signal lines in synchronization with the reset compensating pulse and the data writing prohibiting pulse applied to the selected scanning signal line.
