The invention provides an electro-optical panel that stores data in pixels with a simple structure. In particular, pixels can be provided in association with intersections of data lines and scanning lines. Each of the pixels includes a hold capacitor, an inverter, an OLED element, and first to third transistors. At a reading period, data stored in the hold capacitor is inverted by the inverter and rewritten to the hold capacitor an even number of times. Thus, the logical level of the hold capacitor can be maintained. At a holding period, the second transistor is turned on. Also, the potential of a high potential source at the reading period is set to be higher than that at the holding period, and the potential of a low potential source at the reading period is set to be lower than that at the holding period.
An electro-optical panel, comprising:
An electro-optical panel, comprising:
A driving circuit for driving an electro-optical panel, having a plurality of data lines, a plurality of scanning lines, and pixels provided in association with intersections of the data lines and the scanning lines, the pixels each including:
A driving method for driving an electro-optical panel including a plurality of data lines, a plurality of scanning lines, and pixels provided in association with intersections of the data lines and the scanning lines, the pixels each including an organic light-emitting diode, an electric charge holding device that holds an electric charge, an inverting device that outputs an output signal obtained by inverting an input signal, and a switching device that switches a connection state of the electric charge holding device and the inverting device, output of the inverting device being supplied to the organic light-emitting diode, the driving method comprising:
