A display is disclosed. The display includes electrodes in an edge region of the panels to which AC voltages are applied to reduce the effects of ionic particles.

Display device and method of driving thereof

A driving method for an image display device including sub-pixels arranged in rows and columns, the driving method including: receiving first data corresponding to one frame; dividing the one frame into fields; generating second data from the first data for each of the fields; and supplying the second data to the sub-pixels. Where, the second data is generated by selectively inserting black data in portions of the first data.

Image display device and driving method with selective black data insertion

A method for generating a gamma voltage comprising, a first low voltage and a first high voltage having a first voltage range between the first low voltage and the first high voltage are divided into a plurality of gamma voltages of a first polarity during a first interval. A second low voltage and a second high voltage having a second voltage range between the second low voltage and the second high voltage are divided into a plurality of gamma voltages of a second polarity during a second interval.

Method for generating a gamma voltage, driving circuit therefor, and display device

There is provided a method of driving a gate line, a gate drive circuit for performing the method, and a display apparatus having the gate drive circuit. In the method, a plurality of gate signals, generated from a plurality of shift registers connected to a plurality of gate lines, is applied to the gate lines. An output of the gate signals is blocked during a vertical blanking interval, and then a gate off voltage is applied to the gate lines. Therefore, an output signal of the gate drive circuit may maintain a gate off voltage during a vertical blanking interval in which a clock signal is not applied to a gate drive circuit.
