摘要： A semiconductor device with less power consumption and an electronic appliance using the same. The semiconductor device of the invention is supplied with a first potential from a high potential power source and a second potential from a low potential power source. Upon input of a first signal to an input node, an output node outputs a second signal. With the semiconductor device of the invention, a potential difference of the second signal can be controlled to be smaller than a potential difference between the first potential and the second potential, thereby power consumption required for charging/discharging wires can be reduced.

摘要： Power consumption required for charging and discharging a source signal line is reduced in an active matrix EL display device. A bipolar transistor (Bi1) has a base terminal B connected to an output terminal c1 of an operational amplifier (ON), a collector terminal C connected to a low power potential (GND), and an emitter terminal E connected to a resistor R2. A high power potential (VBH) is a potential in synchronization with a high power potential of a light emitting element. A potential of the output terminal c1 of the operational amplifier (OP1) is outputted as a buffer low power potential (VBL). The low power potential (VBL) corresponds to a potential difference between the high power potential (VBH) and a high power potential (V1). Accordingly, the low power potential (VBL) can follow the high power potential (VBH), that is a high power potential of the light emitting element.

摘要： A light emitting device capable of suppressing generation of pseudo-contours by increasing the frame frequency while suppressing the drive frequency of a driver circuit is provided. According to the present invention, gray scales are displayed not only by controlling the emission period of a light emitting element, but also by controlling the luminance of the light emitting element. Specifically, one frame period is divided into a plurality of sub-frame periods each having an equal length, and the luminance of the light emitting element in each sub-frame period is controlled to have different levels. By controlling the total sum of the luminance level of the sub-frame periods that are selected with a video signal, a desired gray scale can be displayed.
