  • Publication number: 20150042638
    Abstract: A stage circuit includes a first driver, a second driver, a first output unit, a second output unit and a controller. The first driver controls voltages of first and second nodes, according to a first power source, a third power source, a start signal or a carry signal of a previous stage input to a first input terminal, and a clock signal supplied to a second input terminal. The second driver controls voltages of third and fourth nodes, according to voltages of the first power source, the third power source, the first input terminal and the first and second nodes. The first output unit outputs a carry signal to a first output terminal, according to voltages of the first power source, the second input terminal and the third and fourth nodes. The second output unit outputs a scan signal to a second output terminal, according to voltages of the second power source, the second input terminal and the third and fourth nodes. The controller is electrically coupled to the first output terminal and the second driver.

  • Publication number: 20150041628
    Abstract: A light sensitive circuit includes a light sensing capacitor and a driving transistor. The light sensing capacitor is configured to sense light of a predetermined one or more wavelengths. The driving transistor includes a gate electrode electrically connected to the light sensing capacitor and is configured to generate a light sensing current according to a voltage of the gate electrode in the driving transistor. A light sensing accuracy and a light sensing signal to noise ratio (SNR) of the display apparatus including a plurality of such light sensing capacitors may be improved relative to ones that do not include such light sensing capacitors.

  • Publication number: 20140092078
    Abstract: A display device includes a display area including a gate line and a data line and a gate driver connected to an end of the gate line, the gate driver including at least one stages integrated on a substrate configured to output a gate voltage, in which the stage includes an inverter unit and an output unit, in which the output unit includes a first transistor and a first capacitor. The first transistor includes an input terminal applied with a clock signal, a control terminal connected to the node Q, and an output terminal connected to a gate voltage output terminal through which the gate voltage is output. An inverter voltage output from the inverter is lower than the low voltage of the gate voltage output by the output unit.
