DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
First Claim
1. A display device, comprising:
- a display panel comprising;
data lines and gate lines intersecting each other; and
pixels in a matrix;
a timing controller configured to reduce a refresh rate of the pixels in a low-speed driving mode compared to a refresh rate of the pixels in a normal driving mode; and
a display panel driving circuit configured to;
write data to the display panel;
write data to the pixels during N driving frame periods within a unit of time, that is set to the refresh rate of the low-speed driving mode, under the control of the timing controller, where “
N”
is a positive integer of 2 to 4,wherein the pixels are configured to hold a voltage of previous data for a remaining time other than the N driving frame periods of the unit of time.

Abstract
Provided are a display device and method of driving the same. A display device includes: a display panel including: data lines and gate lines intersecting each other, and pixels in a matrix, a timing controller configured to reduce a refresh rate of the pixels in a low-speed driving mode compared to a refresh rate of the pixels in a normal driving mode, and a display panel driving circuit configured to: write data to the display panel, write data to the pixels during N driving frame periods within a unit of time, that is set to the refresh rate of the low-speed driving mode, under the control of the timing controller, where “N” is a positive integer of 2 to 4, wherein the pixels are configured to hold a voltage of previous data for a remaining time other than the N driving frame periods of the unit of time.

7. A method of driving a display device comprising a display panel, comprising data lines and gate lines intersecting each other and pixels in a matrix, and a display panel driving circuit for writing data to the display panel, the method comprising:
-
reducing a refresh rate of the pixels in a low-speed driving mode compared to a refresh rate of the pixels in a normal driving mode; writing data to the pixels during N driving frame periods within a unit of time that is set to the refresh rate of the low-speed driving mode, where “
N”
is a positive integer of 2 to 4; andholding the pixels at a voltage of previous data for a remaining time other than the N driving frame periods of the unit of time. - View Dependent Claims (8, 9, 10)
