Abstract:
A display device including: a display portion with gate lines, a plurality of data lines, TFTs and OLED elements, a scanning line driving circuit which feeds scanning signals for the gate lines; a data line driving circuit which feeds picture image signals for the data lines; a display control controller which provides timing control signals to the scanning line driving circuit and the data line driving circuit and the picture image signals to the data line driving circuit. The timing control signals include a first control signal for driving the TFTs and introducing a light emitting period within each frame period in which the OLED elements are caused to emit light and a second control signal for driving the TFTs and introducing a no-light emitting period within each frame period in which the oled elements are caused to be quenched.
