Abstract:
1. A display device comprising: a plurality of display pixels arranged in a matrix form; a plurality of scanning lines arranged in a row direction of said display pixels; data lines arranged in a column direction of said display pixels; a data line driving circuit configured to supply image data to said data lines; a scanning line driving circuit configured to supply a scanning signal to said scanning lines; a controller configured to control said data line driving circuit and said scanning line driving circuit; each of said display pixels comprising, a plurality of data bit storages which store the corresponding image data in response to the scanning signal, a holding circuit which holds one bit data in the image data stored in said plurality of data bit storages, and conducts refresh operation for said plurality of data bit storages, a lighting controller which controls whether or not to light the display pixels in accordance with a logic of one bit data held in said holding circuit, and a transferring transistor connected between said plurality of data bit storages and said holding circuit; and said holding circuit comprising, two inverters connected in series, and a feedback transistor connected between an output terminal of the inverter at subsequent stage and an input terminal of the inverter at previous stage.
