Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A driving method of a display apparatus, comprising:
generating current control information based on a degree of transition of image data which is to be applied to pixels; and
outputting a target data voltage, corresponding to the image data, to data output channels connected to the pixels,
wherein the outputting of the target data voltage comprises:
applying a rising current or a falling current, which is previously set for outputting the target data voltage, to an output node connected to one of the data output channels; and
selectively and further applying an additional rising current or an additional falling current to the output node on the basis of the current control information, for increasing an output slew rate of the target data voltage,
wherein the additional rising current and the additional falling current are independent of an amplifier bias current, and
wherein, at the output node, the additional rising current is added to the rising current and the additional falling current is added to the falling current.
