Patent ID: 8054251

Claim:
A method for driving a flat panel display in cross-driving a plurality of data-lines comprising the steps of: charging a pre-charging voltage to a storage capacitor connected to a first data-line during a non-light-emitting phase; applying a data waveform signal to a pixel transistor of a second data-line, and allowing a pixel transistor connected to the first data-line to enter a floating state so that the storage capacitor stores a threshold voltage of the pixel transistor connected to the first data-line during the non-light-emitting phase; applying a data waveform signal to the pixel transistor of the first data-line during a light-emitting phase; wherein the pre-charging voltage is lower than the threshold voltage of the pixel transistor connected to the first data-line; and wherein the pixel transistor connected to the second data-line enters a floating state during at least one of the step of performing a pre charging operation of a first data line charging a pre-charging voltage to a storage capacitor connected to a first data-line during a non-light-emitting phase and the step of applying a data waveform signal to the pixel transistor of the first data-line.
