First Claim
1. A display apparatus comprising:
- a liquid crystal panel comprising a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction crossing the first direction, and a plurality of pixels connected to the gate lines and the data lines;
a gate driver applying gate signals to the gate lines;
a data driver applying data voltages to the data lines; and
a timing controller receiving a control signal and image data to apply a gate control signal to the gate driver and to apply a data control signal to the data driver,wherein the pixels comprise pixels arranged in a h-th (h is a natural number) row and pixels arranged in a (h+1)th row, which are adjacent to each other in the second direction such that a (k+1)th (k is a natural number) of the gate lines is disposed between the pixels arranged in the h-th row and the pixels arranged in the (h+1)th row, first pixels displaying a first color and-connected to the (k+1)th gate line among the pixels arranged in the h-th row, and second pixels displaying the first color and-connected to the (k+1)th gate line among the pixels arranged in the (h+1)th row, are spaced apart from each other in the first direction and receive data voltages having different polarities, the image data comprise first pixel data displayed in at least a portion of the first pixels and second pixel data displayed in at least a portion of the second pixels, and when a boundary of a pattern extending in the first direction is disposed between the first and second pixels and the first pixel data have a first grayscale value and the second pixel data have a second grayscale value different from the first grayscale value, the timing controller modulates the first pixel data to be provided to the first pixels to have a grayscale value between the first and second grayscale values and modulates the second pixel data to be provided to the second pixels to have a grayscale value between the first and second grayscale values.

Abstract
A display apparatus includes a liquid crystal panel including gate lines, data lines, and pixels, a gate driver, a data driver, and a timing controller. The pixels include first and second pixels. The first and second pixels are arranged in pixel rows adjacent to each other, arranged in different pixel columns, connected to the same gate line, display the same color, and receive data voltages having different polarities from each other. The image data include first pixel data displayed in the first pixels and second pixel data displayed in the second pixels. When the first pixel data have a first grayscale value and the second pixel data have a second grayscale value different from the first grayscale value, the timing controller modulates the first and second pixel data to allow the first and second pixel data to have a grayscale value between the first and second grayscale values.

18. A method of processing data of a display apparatus, comprising:
-
providing a liquid crystal panel comprising a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction crossing the first direction, and a plurality of pixels connected to the gate lines and the data lines, the pixels comprising pixels arranged in a h-th (h is a natural number) row and pixels arranged in a (h+1)th row, which are adjacent to each other in the second direction such that a (k+1)th (k is a natural number) of the gate lines is disposed between the pixels arranged in the h-th row and the pixels arranged in the (h+1)th row, first pixels displaying a first color and connected to the (k+1)th gate line among the pixels arranged in the h-th row, and second pixels displaying the first color and connected to the (k+1)th gate line among the pixels arranged in the (h+1)th row, being spaced apart from each other in the first direction and receiving data voltages having different polarities; determining whether a boundary extending in the first direction of a pattern of the image data is disposed between the first and second pixels; determining whether a number of the first pixels displaying the pattern or a number of the second pixels displaying the pattern is equal to or greater than a reference number when the boundary extending in the first direction of the pattern of the image data is disposed between the first and second pixels; and modulating the image data comprising first pixel data corresponding to the first pixels and having a first grayscale value and second pixel data corresponding to the second pixels and having a second grayscale value when the number of the first pixels or the second pixels displaying the pattern of the image data is equal to or greater than the reference number to generate first modulated pixel data to be provided to the first pixels to have a third grayscale value between the first and second values and second modulated pixel data to be provided to the second pixels to have a fourth grayscale value between the first and second grayscale values, wherein the image data are not modulated when the boundary extending in the first direction of the pattern of the image data is not disposed between the first and second pixels or the number of the first pixels displaying the pattern or the number of the second pixels displaying the pattern is smaller than the reference number. - View Dependent Claims (19)
