Abstract

A display apparatus includes a plurality of pixels arranged in rows and columns, each pixel column extends in a first direction and each pixel row extends in a second direction crossing the first direction, a first data line extending in the first direction and configured to transfer a data voltage to pixels included in at least two pixel columns, and for each pixel row, a first gate line extending in the second direction and disposed at a first side of the pixel row, and a second gate line extending in the second direction and disposed at a second side of the pixel row, the first and second sides of the pixel row are opposite to each other. In a pair of adjacent pixel columns, pixels, which are connected to the first gate line of their respective pixel row, are arranged in a zigzag arrangement in the first direction.

First claim

What is claimed is:

1. A display apparatus, comprising:
a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixel columns;
a first data line extending in a first direction and configured to transfer a data voltage to pixels in at least two adjacent pixel columns, a first side of a first pixel of a first pixel row extends primarily in the first direction, wherein the first data line is connected to the first pixel of the first pixel row;
a first gate line extending in a second direction crossing the first direction, wherein the first gate line is disposed at a first side of the first pixel row and is connected to the first pixel of the first pixel row, wherein a second side of the first pixel of the first pixel row extends primarily in the second direction, the second side of the first pixel of the first pixel row being longer than the first side of the first pixel of the first pixel row; and
a second gate line extending in the second direction, wherein the second gate line is disposed at the first side of the first pixel row adjacent to the first gate line, and the second gate line is connected to a second pixel of the first pixel row.

2. The display apparatus of claim 1 , further comprising:
a second pixel row adjacent to the first pixel row, the second pixel row including a third pixel and a fourth pixel;
a third gate line and a fourth gate line extending in the first direction and disposed adjacent to each other, wherein the first and second gate lines, together, and the third and fourth gate lines, together, are disposed on opposite sides of the second pixel row; and
a second data line adjacent to the first data line and extending in the first direction, wherein the first and second pixels of the first pixel row and the third and fourth pixels of the second pixel row are disposed between the first and second data lines,
wherein the third pixel of the second pixel row is connected to the third gate line, the fourth pixel of the second pixel row is connected to the fourth gate line, and
wherein the second pixel of the first row is connected to the first data line, the third pixel of the second row is connected to the second data line, and the fourth pixel of the second row is connected to the second data line.

3. The display apparatus of claim 2 , wherein the first and second data lines receive data voltages of different polarities from ach other, and the data voltages charged in the plurality of pixels have a polarity inversion pattern where the data voltages charged in two neighboring pixels, disposed in a same pixel row and between the first and second data lines, have the same polarity.

4. A display apparatus, comprising:
a plurality of pixels arranged in rows and columns;
a first data line extending in a first direction and a second data line adjacent to the first data line, the second data line extending in the first direction and spaced apart from the first data line by at least two columns of pixels, wherein each column of pixels is arranged in the first direction;
first and second pixels disposed in a first row of pixels between the first and second data lines, wherein each row of pixels is arranged in a second direction crossing the first direction, and a first gate line and a second gate line extending in the second direction, wherein the first row of pixels is disposed between the first and second gate lines;
third and fourth pixels disposed in a second row of pixels between the first and second data lines, and a third gate line and a fourth gate line extending in the second direction, wherein the second row of pixels is disposed between the third and fourth gate lines; and
fifth and sixth pixels disposed in a third row of pixels between the first and second data lines, and a fifth gate line and a sixth gate line extending in the second direction, wherein the third row of pixels is disposed between the fifth and sixth gate lines,
wherein the first pixel is connected to the first data line and the second gate line, the second pixel is connected to the first data line and the first gate line, the third pixel is connected to the second data line and the third gate line, the fourth pixel is connected to the second data line and the fourth gate line, the fifth pixel is connected to the first data line and the sixth gate line, and the sixth pixel is connected to the first data line and the fifth gate line,
wherein the first, second and third rows of pixels are consecutively arranged, and
wherein the first through sixth gate lines are each connected to a same gate driver.

5. The display apparatus of claim 4 , wherein, during a first frame, the first data line receives a data voltage of a first polarity, and the second data line receives a data voltage of a second polarity opposite to the first polarity, and
wherein the first and second pixels display a first color, the third and fourth pixels display a second color different from the first color, and the fifth and sixth pixels display a third color different from the first and second colors.
