A display device according to an embodiment of the present inventive concept includes: a substrate including a first region and a second region; and a plurality of pixels disposed on the substrate, wherein the plurality of pixels each include a first data line and a second data line overlapping a pixel electrode, a first capacitance between the first data line and the pixel electrode is smaller than a second capacitance between the second data line and the pixel electrode in a pixel disposed in the first region, and the first capacitance between the first data line and the pixel electrode is larger than the second capacitance between the second data line and a pixel electrode in the pixel disposed in the second region.

Display device

The present disclosure relates to a display device including a substrate, a gate line on the substrate, a data line crossing the gate line, a pixel connected to the gate line and the data line, and a dummy data line disposed at an edge on the substrate and crossing the gate line, wherein the dummy data line includes openings that is disposed on a portion that is near an overlapping portion with the gate line, and portions of the dummy data line separated by the openings are electrically insulated from each other.

A display apparatus includes a display panel, a timing controller, a data driver and a voltage generator. The display panel includes a switching element, a pixel electrode connected to the switching element, a common electrode, a storage electrode and a pixel electrode. The timing controller processes input image data according to a variable frame rate and generates a data signal having a variable frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the pixel electrode. The voltage generator may apply a common voltage to the common electrode and a storage voltage greater than the common voltage to the storage electrode, and/or apply the common voltage varied according to a grayscale value of the input image data. Embodiments may reduce or obviate a display defect caused by luminance differences between frames displayed at different frame rates.

Display apparatus and method of driving display panel thereof

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.
