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 pixel is provided in which normal display of an image is possible even if a sustain period is shorter than an address period in a driving method combining digital gray scales and time gray scales, and in which operation can be compensated by changing the electric potential of a signal line even for a case in which the EL driver transistor becomes normally on due to deterioration. One of a source region and a drain region of an erasure TFT is connected to an electric current supply line, and the remaining one of the source region and the drain region is connected to a gate signal line. It is possible to change the voltage between a gate and a source of an EL driver TFT by changing the electric potential of the gate signal line so that the EL driver TFT is placed in a non-conducting state with certainty with this structure, even for cases in which the EL driver TFT becomes normally on due to a shift in the value of its threshold voltage.

摘要： A plurality of pairs of switch parts and current source circuits are disposed in each pixel. Switching of each of a plurality of the switch parts is controlled by a digital video signal. When the switch part is turned ON, by a current supplied from the current source circuit making a pair with the switch part, the light emitting element emits light. A current which is supplied from one current source circuit to the light emitting element is constant. A value of a current flowing through the light emitting element is comparable to a value of added currents which are supplied to the light emitting element from respective all current source circuits making pairs with the switch parts which are in the conductive states.

摘要： In a conventional display device using light emitting elements, white color cannot be accurately displayed since the luminance of each sub-pixel varies for each color. Therefore, in order to achieve the uniformity in luminance of each sub-pixel, the amount of current or the current density flowing in light emitting elements is required to be changed for each color. In that case, a power source is necessarily provided for each color, thus an external circuit is increased, leading to increase in the cost and power consumption. According to the invention, a variable channel-size MOS transistor is used as a transistor for driving a light emitting element. When a signal voltage applied to a control gate is controlled for each sub-pixel, the amount of current or the current density flowing in light emitting elements can be adjusted and luminance of each sub-pixel can also be adjusted for each color.
摘要翻译：在使用发光元件的常规显示装置中，由于每个子像素的亮度对于每种颜色而变化，因此不能准确地显示白色。因此，为了实现每个子像素的亮度的均匀性，需要为每种颜色改变在发光元件中流动的电流量或电流密度。在这种情况下，必须为每种颜色提供电源，从而增加外部电路，导致成本和功耗的增加。根据本发明，可变通道尺寸MOS晶体管用作驱动发光元件的晶体管。当对每个子像素控制施加到控制栅极的信号电压时，可以调节在发光元件中流动的电流量或电流密度，并且还可以针对每种颜色调整每个子像素的亮度。

摘要： A semiconductor device in which a transistor can supply an accurate current to a load (EL pixel and signal line) without being influenced by variations is provided.A voltage at each terminal of a transistor is adjusted by a feedback circuit using an amplifier circuit. A current Idata is input from a current source circuit to the transistor, and a gate-source voltage is set by the feedback circuit so that the transistor can flow the current Idata. The feedback circuit controls the transistor to operate in a saturation region. Thus, a gate voltage required for flowing the current Idata is set. With the use of the set transistor, a current can be supplied to a load (EL pixel and signal line) with accuracy. Note that a desired gate voltage can be set quickly since the amplifier circuit is utilized.

摘要： In a light emitting device, luminance irregularities caused by fluctuation in threshold of TFTs for supplying a current to EL elements among pixels hinder the light emitting device from improving the image quality. A voltage equal to the threshold of a TFT 110 is held in capacitor means 111 in advance. When a video signal is inputted from a source signal line, the voltage held in the capacitor means is added to the signal, which is then applied to a gate electrode of the TFT 110. Even when threshold is fluctuated among pixels, each threshold is held in the capacitor means 111 of each pixel, and therefore, influence of the threshold fluctuation can be removed. Since the threshold is stored in the capacitor means 111 alone and the voltage between two electrodes is not changed while a video signal is written, fluctuation in capacitance value has no influence.
