Abstract:
1. A single-sided driver used with a display panel, the single-sided driver comprising: a single-sided driver circuit having separate current flow paths coupled to each of X and Y axes electrodes of the display panel, the single-sided driver circuit having predetermined circuit elements including energy accumulation elements and switching elements, and establishes current in the current flow paths to generate respective predetermined driving voltage waveforms on the X and Y axes electrodes according to predetermined switching sequences to drive the display panel, wherein the single-sided driver circuit comprising: an isolation and reset circuit combination which isolates an energy recovery path and establishes a current flow path to generate reset voltage waveforms that are supplied to both the X and Y axes electrodes to eliminate wall charges in the display panel during a reset period; a scan pulse generation circuit which establishes a current flow path to generate address discharging voltage waveforms to be supplied to the X and Y axes electrodes to generate wall charges in the display panel during an address period; and a sustain driver circuit which establishes charging/discharging paths to charge/discharge the display panel according to the predetermined switching sequences to drive the display panel during a sustain discharge period, and establishes a current flow path to generate the reset voltage waveform and the address discharging voltage waveforms during the reset period and the address period, respectively, in combination with the isolation and reset circuit and the scan pulse generation circuit.
