摘要： The invention provides a semiconductor device which performs a write operation of a signal current rapidly to a current input type pixel. Before inputting a signal current, a precharge operation is performed by flowing a large current. After that, a signal current is inputted to perform the set operation. A predetermined potential can be obtained rapidly as the precharge operation is performed before the set operation. The predetermined potential is approximately equal to a potential after completing the set operation. Therefore, the set operation can be rapidly performed and a write operation of a signal current can be rapidly performed. By using two transistors, a gate width W can be long or a gate length L can be short in the precharge operation or the gate width W can be short and the gate length L can be long in the set operation.

摘要： A pixel having a transistor which controls a current value supplied to a load, a first storage capacitor, a second storage capacitor, and first to fourth switches is included. After the threshold voltage of the transistor is held in the second storage capacitor, a potential in accordance with a video signal is input to the pixel. Voltage obtained by adding a potential in which the potential in accordance with the video signal and the first storage capacitor are capacitively divided to the threshold voltage is held in the second storage capacitor in this manner, so that variation of a current value caused by variations in the threshold voltage of the transistor is suppressed. Thus, desired current can be supplied to the load such as a light-emitting element. In addition, a display device with little deviation from luminance specified by the video signal can be provided.

摘要： A transistor whose channel region includes an oxide semiconductor is used as a pull down transistor. The band gap of the oxide semiconductor is 2.0 eV or more, preferably 2.5 eV or more, more preferably 3.0 eV or more. Thus, hot carrier degradation in the transistor can be suppressed. Accordingly, the circuit size of the semiconductor device including the pull down transistor can be made small. Further, a gate of a pull up transistor is made to be in a floating state by switching of on/off of the transistor whose channel region includes an oxide semiconductor. Note that when the oxide semiconductor is highly purified, the off-state current of the transistor can be 1 aA/μm (1×10−18 A/μm) or less. Therefore, the drive capability of the semiconductor device can be improved.

摘要： It is an object of the present invention to provide a display device in which images can be seen under a dark place to intense external light. In the display device, display is performed by changing the gray scale number depending on external light intensity, and display modes can be switched depending on contents displayed on the screen. An analog mode and a digital mode are switched depending on external light intensity. In an analog digital switching circuit, when a video signal is an analog value, a signal is outputted to a pixel array without any change and, when the video signal is a digital value, the signal is outputted to a circuit that performs a digital operation such as a latch circuit. Consequently, display gray scales of a pixel are changed appropriately. Accordingly, a clear image can be displayed. For example, it is possible to ensure visibility in a wide range of a dark place or under indoor florescent light to outdoor sun light.

摘要： Solved is a problem of attenuation of output amplitude due to a threshold value of a TFT when manufacturing a circuit with TFTs of a single polarity. In a capacitor (105), a charge equivalent to a threshold value of a TFT (104) is stored. When a signal is inputted thereto, the threshold value stored in the capacitor (105) is added to a potential of the input signal. The thus obtained potential is applied to a gate electrode of a TFT (101). Therefore, it is possible to obtain the output having a normal amplitude from an output terminal (Out) without causing the amplitude attenuation in the TFT (101).
