  • Driver and electronic device
    Patent number: 9697762
    Abstract: In a display device including a driver that drives load lines in an electro-optical panel through capacitor charge redistribution, load capacitance among the load lines of the electro-optical panel differs depending on parasitic capacitance of a board on which the load lines are mounted, the type of the panel, and so on, and the accuracy of driving voltages drops due to such variations. The driver is provided with a adjusting capacitance group that corrects variation in load capacitance, and by adjusting a driving capacitance on the driver side, a ratio with the load capacitance is increased and accuracy of a post-driving potential is increased.

  • Driver having capacitor circuit including first to nth capacitors provided between first to nth capacitor driving nodes and a data voltage output terminal
    Patent number: 9679529
    Abstract: In a display device including a driver that drives a load line of an electro-optical panel through capacitor charge redistribution, a data voltage will change in the case where an electro-optical panel-side capacitance changes, even when tone data is the same. Accordingly, by detecting a voltage at a data voltage output terminal, a connection state and outputs between the data voltage output terminal and the electro-optical panel can be detected.

  • DRIVER AND ELECTRONIC DEVICE
    Publication number: 20160111035
    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.
