Patent ID: 7006067

Claim:
A display device comprising: a plurality of pixel elements arranged in rows and columns; a plurality of scanning lines, each scanning line corresponding to a respective row and transmitting a selection signal to pixel elements in the corresponding row; a plurality of data lines, each data line corresponding to a respective column, each data line transmitting a data signal to pixel elements in a corresponding column; a plurality of selection transistors, each selection transistor corresponding to a respective pixel element and transmitting a data signal on a corresponding data line to the corresponding pixel element, in response to a selection signal on the corresponding scanning line; a plurality of holding capacitance elements, each holding capacitance element corresponding to a respective selection transistor and holding a voltage applied to the corresponding pixel element; refresh circuitry for reading out holding voltages of the holding capacitance elements in response to a refresh instruction, and refreshing and restoring the holding voltages of the holding capacitance elements in accordance with the holding voltage signals read out; and, a row selection circuit for driving the scanning lines to a selected state, in a predetermined order, in response to the refresh instruction and coupling the holding capacitance elements on a selected row to corresponding data lines, wherein the data lines are arranged in pairs, and the refresh circuitry comprises, for each column, a data line control circuit for connecting the pairs of data lines to respective pairs of complementary signal lines, in response to the refresh instruction; a voltage setting circuit selectively activated in response to the refresh instruction, for setting the pairs of complementary signal lines to a predetermined voltage level, when activated. a differential amplification circuit, corresponding to each pair of complementary signal lines and selectively activated in response to the refresh instruction, for differentially amplifying the voltages of the corresponding pair of complementary signal lines, when activated.
