摘要： There is provided a semiconductor device in which fabrication steps can be reduced by constructing a circuit using only TFTs of one conductivity type and in which a voltage amplitude of an output signal can be normally obtained. A capacitance (205) is provided between a gate and a source of a TFT (203) connected to an output node, and a circuit formed of TFTs (201) and (202) has a function to bring a node a into a floating state. When the node α is in the floating state, a potential of the node a is caused higher than VDD by using gate-source capacitance coupling of the TFT (203) through the capacitance (205), thus an output signal having an amplitude of VDD-GND can be normally obtained without causing amplitude attenuation due to the threshold value of the TFT.

摘要： To provide a novel driving method for driving an electronic device by using digital gray scale and time gray scale in combination, which secures high duty ratio, which can display an image normally even when a sustain period is shorter than an address period, and which is hardly affected by dulled signal waveform. In a sub-frame period (102) where a sustain period is shorter than an address period, a clear period (105) is squeezed in between completion of a sustain period (104) and start of an address period of the subsequent sub-frame period. The length of the sustain period (104) thus can be set without being limited by the length of an address period (103). This non-display period is provided by changing the electric potential of a storage capacitor line. Therefore, unlike the case where the non-display period is provided by changing the electric potential of a cathode wiring, the present invention is hardly affected by dulled signal waveform.

摘要： A circuit is provided which is constituted by TFTs of one conductivity type, and which is capable of outputting signals of a normal amplitude. When an input clock signal CK1 becomes a high level, each of TFTs (101, 103) is turned on to settle at a low level the potential at a signal output section (Out). A pulse is then input to a signal input section (In) and becomes high level. The gate potential of TFT (102) is increased to (VDD−V thN) and the gate is floated. TFT (102) is thus turned on. Then CK1 becomes low level and each of TFTs (101, 103) is turned off. Simultaneously, CK3 becomes high level and the potential at the signal output section is increased. Simultaneously, the potential at the gate of TFT (102) is increased to a level equal to or higher than (VDD+V thN) by the function of capacitor (104), so that the high level appearing at the signal output section (Out) becomes equal to VDD. When SP becomes low level; CK3 becomes low level; and CK1 becomes high level, the potential at the signal output section (Out) becomes low level again.

摘要： An electro-optical device with a pixel portion of enhanced definition is provided, which uses pixels having a novel structure so that the number of stages of a source signal line side driver circuit is reduced to half the number of pixels in the horizontal direction, thereby making a space for placing the driver circuit and increasing the aperture ratio. One horizontal period is divided into the former half and the latter half. Signals for two adjacent pixels are successively inputted to one source signal line. A pixel selecting portion is provided between the two adjacent pixels. The signal selecting portion selects one of the pixels in the former half of one horizontal period so that a signal is written in the pixel whereas it selects the other pixel during the latter half of the horizontal period so that a signal is written in the pixel. Since one source signal line is shared between two adjacent pixels, the invention is advantageous also in terms of aperture ratio.

摘要： A pulse is input to first and second TFTs to turn ON the first and second TFTs so that the potential of a node α rises. When the potential of the node α reaches (VDD−VthN), the node α enters a floating state. Accordingly, a third TFT then turns ON, and potential of an output node rises as a clock signal reaches the level H. On the other hand, potential of a gate electrode of the third TFT further rises due to an operation of capacitance as the potential of the output node rises, so that the potential of the output node would be higher than (VDD+VthN). Thus, the potential of the output node rises to VDD without voltage drop caused by a threshold of the third TFT.

摘要： The invention provides a display device and an electronic apparatus which can reduce power consumption in the case of being driven by using a digital time grayscale method. According to the invention, a row in which all the pixels display black is focused on in a plurality of pixels arranged in matrix, and sampling of data which is to be inputted to the pixels arranged in the row is not performed. Then, in a period during which the data sampling is not performed, the operation of a shift register in a source driver and, sampling operation of a video signal in a first latch circuit are stopped. The invention which has the aforementioned characteristics can temporally stop operation of the source driver to reduce power consumption. In particular, the invention can stop operation of the source driver which consumes much power in the display device, leading to dramatic reduction in power consumption.
