Abstract:
1. A display device comprising: a pixel element configured to emit light; a current line coupled to the pixel element; and a driving circuit including a holding unit, a first transistor, a second transistor, a third transistor, a fourth transistor and a fifth transistor, wherein the holding unit is configured to hold a luminance data voltage corresponding to an image information signal, the third transistor and the fourth transistor are connected to the first transistor, and the fifth transistor is connected to the holding unit, and wherein the driving circuit is configured to operate such that: a reset signal and the image information signal are sequentially written to the holding unit, via the fifth transistor and the second transistor, respectively, during a predetermined period; the fourth transistor electrically connects a current node of the first transistor to a gate node of the first transistor; the third transistor switches current flow on and off from the first transistor to the current line, and is set in an off state in at least a portion of the predetermined period; and the first transistor transforms the luminance data voltage in the holding unit into a current signal, the current signal being supplied to the pixel element through the current line.
