Abstract:
1. 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,
