A method of driving a display panel includes charging a pixel with first data during a first charging period, comparing a first grayscale of the first data and a second grayscale of second data, charging the pixel with compensated data during a second charging period if the first grayscale is greater than the second grayscale, and charging the pixel with the second data during a third charging period.

Method of driving display panel and display apparatus for performing the same

In a display panel and a display apparatus having the display panel, the display panel includes array and opposite substrates. The array substrate includes display and peripheral areas. Gate and source lines are formed in the display area. A gate driving part and first and second clock lines are formed in the peripheral area. The gate driving part outputs gate signals to the gate line. The first and second clock lines respectively transmit first and second clock signals to the gate driving part. The opposite substrate is combined with the array substrate and includes a common electrode layer. The common electrode layer has an opening portion patterned to expose the first and second clock lines. The exposed portions of the first and second clock lines have substantially the same area. Thus, delays of the gate signals may be minimized and distortion of the gate signals may be prevented.

Display panel and display apparatus having the same

A liquid crystal display includes a liquid crystal layer disposed between first and second substrates. A gate line transmits gate signals; a first data line transmits data voltages; a first voltage line alternately transmits a first voltage and a second voltage that is than greater than the first voltage; a first switching element is connected to the gate line and the first data line; a second switching element is connected to the gate line and the first voltage line; a first pixel electrode is connected to the first switching element; and a second pixel electrode is connected to the second switching element. The first pixel electrode and the second pixel electrode form a liquid crystal capacitor along with the liquid crystal layer, and at least one of the first voltage and the second voltage is variable.

Liquid crystal display and driving method thereof

A method for reducing noise of a touch panel includes: generating a detection signal including at least one contact region; generating a combination noise region including at least a portion of the at least one contact region; and generating a final detection signal. The generating the final detection signal includes removing the combination noise region from the detection signal.

Touch panel and noise reducing method therefor

A liquid crystal display device includes a liquid crystal panel including a pad electrode, a tape circuit substrate and an anisotropic conductive film. The pad electrode receives one of a driving signal and a power supply voltage signal. The tape circuit substrate includes a base film made of an insulating material, and a signal line formed on the base film and having a slit at a portion of the signal line which overlaps the pad electrode of the liquid crystal panel. The anisotropic conductive film connects the outer lead with the pad electrode.
