摘要： A display device and a driving method thereof are provided, which reduces an instantaneous current generated with a charge and discharge of source signal lines and further reduces a load to a power supply line. According to the invention, source signal lines are divided into the first to the n-th groups so as to be charged or discharged according to the first to the n-th latch pulses which are inputted at different timing. Since the number of the source signal lines which start to be charged or discharged at the same time is reduced, an instantaneous current generated with the charge and discharge can be reduced, and a load to the power supply line can be reduced as well.

摘要： A semiconductor display device that operates normally at a room temperature may not operate normally at a low temperature. Meanwhile, in semiconductor display devices with the same circuit configuration and the same driving method, the higher the operating frequency is, the better the display quality is. Thus, a semiconductor display device the operating frequency of which is set on the basis of a room temperature may not operate normally at a low temperature. According to the invention, the temperature and the operating state of a semiconductor display device are measured to vary the operating frequency in accordance with the measurement result. More specifically, the operating frequency is decreased at a low temperature to obtain normal operation, while the operating frequency is increased at a room temperature and a high temperature to improve the display quality.

摘要： According to a driving method of applying a reverse bias voltage, capacitance occurs due to a stacked structure of a conductor, an insulator and a conductor, or due to a structure of a TFT. This capacitance prevents normal operation. The invention provides a pixel configuration including at least a driving transistor for driving a light emitting element and a switching transistor for controlling the driving transistor, wherein the switching transistor is turned on in the case of applying a forward bias voltage after applying a reverse bias voltage. As a result, it is prevented that the potential changes due to unwanted capacitive coupling.

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.
