摘要： The present invention aims to provide a monolithic driver-type display device capable of reducing circuit scale of a sampling circuit, and keeping low power consumption by directly driving a source driver with an externally provided video signal.In the monolithic driver-type display device having a display portion for displaying video and circuits for driving the display portion formed on the same insulating substrate, a plurality of sampling switches are provided in association with a plurality of pieces of bit data contained in externally inputted digital video signals. The sampling switches are opened/closed based on sampling signals, thereby sampling the digital video signals for each piece of the bit data and converting the signals into parallel format for output to data lines. The outputted digital video signals charge parasitic capacitances on the data lines and are held therein.

摘要： A display device is provided with a shift register having a plurality of bistable circuits, each of the bistable circuits being connected to a corresponding scanning line. An RS flip-flop circuit provided in each of the bistable circuits functions as a memory portion for discriminating a start position of a display region for partial display. When partial display is carried out, first, only the RS flip-flop circuit corresponding to the start position of the display region is put into the set state, that is, only the bistable circuit corresponding to the start position of the display region is put into the set state. Moreover, the scanning lines that are connected to the bistable circuits from the start position to the end position are driven sequentially. During this, only the bistable circuit corresponding to the start position is kept in the set state, and the other bistable circuits are kept in the reset state.

摘要： By reducing the potential drop of a storage node that occurs due to feedthrough, the capacitance of a storage capacitor is reduced and sensor sensitivity is improved. In a photosensor, the first terminal of a storage capacitor (C2) and the gate of a MOS transistor (M1), which outputs a signal in accordance with the potential of a storage node (N2), are connected to the storage node (N2). A forward biased pulse voltage is supplied to the anode of a first photodiode (DS) in a reset period, and a reverse biased voltage is supplied to the anode of the first photodiode in a storage period and a readout period. A reverse biased voltage is supplied to the anode of a second photodiode (DM) in all operation periods. A voltage that keeps the potential of the storage node lower than the threshold value of the MOS transistor (M1) is supplied to the second terminal of the storage capacitor in the reset period and the storage period, and a voltage that thrusts the potential of the storage node (N2) upward to the threshold value of the MOS transistor (M1) or higher is supplied to the second terminal of the storage capacitor in the readout period.

摘要： A plurality of sensor circuits each including an optical sensor and a charge retention transistor each provided between a reset line and an accumulation node are arranged in a pixel region of a display device. In a sensing period, a LOW-level voltage is applied as a reset cancellation voltage to the reset line RSTa, and a HIGH-level voltage is applied to a control line CLKa to control the charge retention transistor to be in an ON state. In a period other than the sensing period, the LOW-level voltage is applied to the control line CLKa to control the charge retention transistor to be in an OFF state, and the HIGH-level voltage is applied as a retention voltage to the reset line RSTa. Thus, a drain-source voltage Vds of the charge retention transistor is lowered, a leakage current through the charge retention transistor is reduced, and a light detection accuracy is enhanced. A substantially middle voltage between a reset voltage and a voltage at an accumulation node at the sensing of a maximum amount of light may be used as the retention voltage.

摘要： A level-shifter is combined with a bi-directional shift register. The level shifter turns a start signal of the bi-directional shift register to be an enable signal, and (i) activates a level shifting section by supplying a stationary current, during a period in which the enable signal is HIGH, while (ii) deactivates the level shifting section by cutting off the stationary current, during a period in which the enable signal EN is LOW. With this, it is possible to reduce unnecessary current consumption by a level shifter provided for a signal which does not frequently change, such as a shifting direction switching signal for which the bi-directional shift register is provided. At the same time, when such a signal changes, the change is followed with no time lag.
摘要翻译：电平移位器与双向移位寄存器组合。电平移位器将双向移位寄存器的起始信号变为使能信号，（i）在使能信号为高电平的期间通过提供稳定电流来激活电平移位部分，而（ii）在使能信号EN为低电平的时间段期间，通过切断稳定电流来停止电平转换部分。由此，可以减少为不频繁变化的信号设置的电平移位器，例如设置有双向移位寄存器的移位方向切换信号来减少不必要的电流消耗。同时，当这种信号发生变化时，随之而来的是变化，没有时间滞后。
