Abstract:
1. A display device including pixels arranged in rows and columns, the display device comprising: a signal line driving circuit that selectively outputs, to an output line disposed in each of the columns, a standard voltage and a signal voltage that determines luminance of the pixels; a first signal line and a second signal line that are disposed in each of the columns, for applying the standard voltage or the signal voltage to the pixels; a selector disposed in each of the columns, for applying the standard voltage or the signal voltage outputted from the output line selectively to one of the first signal line and the second signal line; a first power source line and a second power source line; and a scanning line disposed in each of the rows, wherein the pixels compose at least two driving blocks each of which includes at least two of the rows, each of the pixels includes: each of the pixels in a k-th driving block of the driving blocks further includes a first switching transistor that includes a gate connected to the scanning line, one of a source and drain connected to the first signal line, and the other of the source and the drain connected to the current control unit, and switchably interconnects the first signal line and the current control unit, k being a positive integer, each of the pixels in a (k+1)-th driving block of the driving blocks further includes a second switching transistor that includes a gate connected to the scanning line, one of a source and a drain connected to the second signal line, and the other of the source and the drain connected to the current control unit, and switchably interconnects the second signal line and the current control unit, at least one of a threshold voltage detection period and an initializing period is provided in common for the pixels in a same one of the driving blocks, and at least one of the threshold voltage detection period and the initializing period provided in common in the same one of the driving blocks is provided independently for the pixels in different ones of the driving blocks, the threshold voltage detection period being a period during which the threshold voltage is detected when the standard voltage is applied to the current control unit, and the initializing period being a period during which the current control unit is initialized, and the display device further comprises a selector control unit configured to cause the selector to, in one frame period, apply the signal voltage to the pixels in the k-th driving block via the first signal line and subsequently apply the standard voltage to the first signal line, and apply the signal voltage to the pixels in the (k+1)-th driving block via the second signal line and subsequently apply the standard voltage to the second signal line.
