Abstract

A display apparatus includes a display panel and a first gate driver. The display panel includes a plurality of data lines extending in a first direction, and a plurality of gate lines extending in a second direction obliquely inclined toward the first direction and spaced apart from each other in a third direction crossing the second direction. The plurality of gate lines includes a first gate line group and a second gate line group respectively disposed in first and second display areas of the display panel. The first gate driver is configured to drive at least one gate line of the second gate line group while driving at least one gate line of the first gate line group.

First claim

What is claimed is:

1 . A display apparatus, comprising:
a display panel comprising a plurality of data lines extending in a first direction, and a plurality of gate lines extending in a second direction obliquely inclined toward the first direction and spaced apart from each other in a third direction crossing the second direction, wherein the plurality of gate lines comprises a first gate line group and a second gate line group, the first gate line group is disposed in a first display area of the display panel, and the second gate line group is disposed in a second display area of the display panel; and a first gate driver configured to drive at least one gate line of the second gate line group while driving at least one gate line of the first gate line group.

2 . The display apparatus of claim 1 , wherein the first gate driver is configured to sequentially drive the first gate line group for a first period and the second gate line group for a second period, wherein at least a portion of the second period overlaps the first period.

3 . The display apparatus of claim 2 , wherein the first gate driver is configured to simultaneously output gate signals to the at least one gate line of the first gate line group and the at least one gate line of the second gate line group during the portion of the second period that overlaps the first period.

4 . The display apparatus of claim 2 , wherein the first gate driver is configured to drive the first gate line group and the second gate line group in the third direction.

5 . The display apparatus of claim 2 , wherein the first gate driver is configured to drive the first gate line group and the second gate line group in a direction opposite to the third direction.

6 . The display apparatus of claim 1 , wherein the first gate driver is alternately connected to the first gate line group and the second gate line group at a first longer side of the display panel.

7 . The display apparatus of claim 6 , wherein the second gate line group is electrically connected to the first gate driver through gate sub-lines extending in the first direction.

8 . The display apparatus of claim 7 , wherein the gate sub-lines are connected to the first gate driver at the first longer side of the display panel, and the gate sub-lines are connected to the second gate line group at a second longer side of the display panel opposite to the first longer side.

9 . The display apparatus of claim 1 , wherein each of the gate lines of the first and second gate line groups comprises a plurality of unit portions,
wherein each of the unit portions comprises a first portion extending in the first direction, a second portion extending in a fourth direction crossing the first direction, and a connecting portion extending in the second direction and connecting the first portion and the second portion, wherein the unit portions are continuously connected to each other in the second direction.

10 . The display apparatus of claim 9 , wherein the display panel further comprises a plurality of pixel units arranged in a matrix configuration, and each of the pixel units is electrically connected to an adjacent gate line of the plurality of gate lines and an adjacent data line of the plurality of data lines.

11 . A method of driving a display apparatus, comprising:
sequentially driving gate lines of a first gate line group disposed in a first display area of a display panel for a first period; and sequentially driving gate lines of a second gate line group disposed in a second display area of the display panel for a second period, wherein at least a portion of the second period overlaps the first period.

12 . The method of claim 11 , wherein at least one gate line of the first gate line group and at least one gate line of the second gate line group simultaneously receive a gate signal during the portion of the second period that overlaps the first period.

13 . The method of claim 11 , wherein the display panel comprises a plurality of data lines extending in a first direction, and the gate lines of the first gate line group and the gate lines of the second gate line group extend in a second direction obliquely inclined toward the first direction.

14 . The method of claim 13 , wherein the gate lines of the first gate line group and the gate lines of the second gate line group are alternately connected to a first gate driver that is configured to receive gate signals, and
the gate lines of the second gate line group are electrically connected to the first gate driver through gate sub-lines extending in the first direction.

15 . The method of claim 14 , further comprising:
sequentially driving gate lines of a third gate line group disposed in a third display area of the display panel for a third period, wherein at least a portion of the third period overlaps the first period, the first display area is disposed between the second display area and the third display area, and the gate lines of the third gate line group are connected to a second gate driver that is configured to receive the gate signals.

16 . The method of claim 15 , further comprising:
sequentially driving gate lines of a fourth gate line group disposed in a fourth display area of the display panel for a fourth period, wherein the fourth display area is disposed between the first display area and the third display area; and sequentially driving gate lines of a fifth gate line group disposed in a fifth display area of the display panel for a fifth period, wherein the fifth display area is disposed between the first display area and the second display area, wherein the gate lines of the fourth gate line group and the gate lines of the fifth gate line group are alternately connected to a third gate driver that is configured to receive the gate signals, and the gate lines of the fifth gate line group are electrically connected to the third gate driver through gate sub-lines extending in the first direction.

17 . The method of claim 15 , wherein the first gate driver sequentially drives the gate lines of the second gate line group after driving at least one gate line of the first gate line group.

18 . A method of driving a display apparatus, comprising:
driving at least one gate line of a first gate line group of a plurality of gate lines and at least one gate line of a second gate line group of the plurality of gate lines at substantially a same time, wherein the plurality of gate lines and a plurality of data lines are disposed in a display panel, wherein the plurality of data lines extends in a first direction, wherein the plurality of gate lines extends in a second direction obliquely inclined toward the first direction, and are spaced apart from each other in a third direction crossing the second direction, wherein the first gate line group is disposed in a first display area of the display panel and the second gate line group is disposed in a second display area of the display panel.

19 . The method of claim 18 , further comprising:
driving the first gate line group for a first period and the second gate line group for a second period, wherein at least a portion of the second period overlaps the first period.

20 . The method of claim 19 , further comprising:
simultaneously outputting gate signals to the at least one gate line of the first gate line group and the at least one gate line of the second gate line group during the portion of the second period that overlaps the first period.
