  • Patent number: 9874794
    Abstract: Gate-driving circuitry of a thin film transistor array panel is formed on the same plane as a display area of the transistor array panel. The gate-driving circuitry includes driving circuitry and signal lines having apertures. Thus, a sufficient amount of light, even though illuminated from the thin film transistor array panel side, can reach a photosetting sealant overlapping at least in part the gate-driving circuitry. The thin film transistor array panel and the counter panel are put together air-tight and moisture-tight. Consequently, the gate-driving circuitry can avoid corrosion by moisture introduced from outside. Gate-driving circuitry malfunctions can also be reduced.

  • Patent number: 9842527
    Abstract: In a display device having a driver that drives load lines in an electro-optical panel through capacitor charge redistribution, a data voltage is determined by a capacitance ratio during capacitive driving. However, a panel-side capacitance is a capacitance external to a driver IC, and thus it is difficult to set the capacitance ratio exactly. Accordingly, voltage driving, which outputs a data voltage corresponding to tone data to a data voltage output terminal using a voltage driving circuit, is carried out after capacitive driving that drives the electro-optical panel has been started.
