Abstract:
1. A panel comprising: pixels arranged in a matrix state, each including: power supply lines, each respective power supply line corresponding to a different row of the pixels and being configured to propagate power supply signals to pixels of the row to which the respective power supply line corresponds; scanning lines, each respective scanning line corresponding to a different row of the pixels and being configured to propagate scanning control signals to pixels of the row to which the respective scanning line corresponds; a power supply control circuit configured to selectively switch potentials of the power supply signals propagated on the power supply lines between a high power supply potential and a low power supply potential, wherein the power supply lines are grouped into units that each comprise n≧2 different ones of the power supply lines such that the potentials of the power supply signals that are propagated on those of the power supply lines that are grouped into a same unit correspond to each other and the power supply control circuit is configured to switch the potentials of the power supply signals that are propagated on those of the power supply lines that are grouped into a same unit between the high power supply potential and the low power supply potential at same timings; a scanning control circuit configured to switch a potential of the scanning control signal between a high scanning potential and a low scanning potential, wherein conduction of the sampling transistor of each of the respective pixels is controlled by the switching of the potential of the scanning control signal propagated on the scanning line corresponding to the row of the respective pixel; and a data circuit configured to repeatedly switch the potential of the video signal during horizontal scanning periods, wherein:
