Abstract: 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.

Abstract: A display device includes a gate line; first and second adjacent data lines intersecting the gate line; a first sub-pixel electrode between the first and second data lines; a second sub-pixel electrode between the first gate line and the first sub-pixel electrode; a first switching element connected to the first gate line, the first data line and the first sub-pixel electrode; a second switching element connected to the first gate line, the first data line and the second sub-pixel electrode; a connection electrode connecting the first sub-pixel electrode and the first switching element; a first dummy electrode between the first data line and the second sub-pixel electrode; and a second dummy electrode extending from the connection electrode and is disposed closer to the first data line than the second data line. End portions of the first and second dummy electrodes face each other.

Abstract: Each stage of a gate driver includes a controlling part which increases an electric potential of a boosting line in response to a carry signal of a previous stage and decreases the electric potential of the boosting line in response to the carry signal of a next stage, a first output part which turns on in response to the increased electric potential of the boosting line and receiving a clock signal to output a gate signal of a present stage, and a second output part which turns on in response to the increased electric potential of the boosting line and receiving the clock signal to output the carry signal of the present stage. The boosting line of the present stage is disposed adjacent to a gate line which is connected to one of next stages following the present stage.
