  • Publication number: 20160328056
    Abstract: A touch display substrate includes a substrate including a display region and a non-display region; a touch sensing circuit in the non-display region; a plurality of touch sensing electrodes in the display region, the plurality of touch sensing electrodes grouped into at least two touch sensing electrode groups in accordance with distances from the touch sensing electrodes to the touch sensing circuit; and a plurality of touch leads, where one end of each of the touch leads is electrically connected with one of the touch sensing electrodes, and the other end of the touch lead is electrically connected with the touch control circuit. The touch sensing circuit is configured to input touch driving signals of a different frequency to each of the touch sensing electrode groups, and the touch driving signals input to the touch sensing electrodes in the same touch sensing electrode group are of the same frequency.

  • Publication number: 20150187336
    Abstract: A driving circuit includes first and second source driving circuits, and first and second control units. Each of the first and second control units includes multiple first control subunits. Each of the first control subunits includes a control end, an input end, and an output end. The control end receives a control signal to turn on or off the first control subunit. The input end receives a clock signal. The output end is connected with the associated source driving circuit. The first and second control units enable switching between the unilateral driving mode and the bilateral driving mode for the clock signal.
