Patent ID: 8115705

Claim:
An active matrix type display device comprising: an active matrix type display array made up of pixel circuits arranged in a row and column matrix form, each pixel circuit includes a current-driven diode type light-emitting element and a plurality of thin-film transistor for controlling the diode type light-emitting element; a data line provided for each column of the matrix for supplying a data signal to the pixel circuits on the corresponding column; a data driver for controlling the supply of the data signal to the data line; a gate line provided for each row of the matrix for supplying a selection signal to pixel circuits on the corresponding row; a gate driver for supplying the selection signal to the gate line; and a control circuit for controlling the data driver and gate driver, wherein the data driver switches a plurality of sets of video signals alternately and supplies the video signals to the data line, wherein the data driver further switches between the plurality of sets of video signals at least for each frame or each line and supplies the video signals to the data line, wherein the pixel circuit comprises: a storage capacitance, the potential at one end of which is fixed to a predetermined potential; a gate transistor, having one non-control terminal connected to a non-fixed potential terminal of the storage capacitance, an other non-control terminal connected to the data line and a control terminal connected to the gate line; a drive transistor, having its control terminal connected to a non-fixed potential terminal of a reset capacitance and the non-control terminal connected to a power line, for controlling a drive current to the diode type light-emitting element; an ON control transistor, having its control terminal connected to the ON line, one non-control terminal connected to the other non-control terminal of the drive transistor, and the other non-control terminal connected to the diode type light-emitting element, for controlling ON/OFF of the drive current of the diode type light-emitting element; and a reset transistor, having its control terminal connected to a first reset line, one non-control terminal connected to the other non-control terminal of the drive transistor and the non-control terminal of the ON control transistor, and an other non-control terminal connected between the control terminal of the drive transistor and the non-fixed potential terminal of the reset capacitance.
