Patent ID: 7208294

Claim:
A display device comprising: a matrix display panel including a plurality of driving lines, a plurality of scan lines intersecting with said plurality of driving lines, and a plurality of pixel portions which are arranged at the intersecting portions by said plurality of driving lines and said plurality of scan lines and which each include a series circuit of a bistable element and a light emitting element, wherein when a voltage exceeding a turn-on threshold voltage is applied to said series circuit, said bistable element is in an ON state to allow said light emitting element to electrically connect between a driving line and a scan line associated with said series circuit until a voltage lower than a turn-off threshold voltage is applied to said series circuit, and when a voltage lower than the turn-off threshold voltage is applied to said series circuit, said bistable element is in an OFF state to allow said light emitting element to electrically disconnect between said driving line and said scan line associated with said series circuit until a voltage exceeding the turn-on threshold voltage is applied to said series circuit; a controller which specifies in order one scan line of said plurality of scan lines in accordance with scan timing of an input image signal, and specifies a driving line corresponding to at least one pixel portion to be driven to emit light on said one scan line in accordance with the input image signal; and a driver which applies, every time said one scan line is specified, a first predetermined voltage which is lower than the turn-off threshold voltage, between said one scan line and the specified driving line, and thereafter applies a second predetermined voltage which is higher than the turn-on threshold voltage, between said one scan line and the specified driving line.
