Abstract

A display apparatus includes a light source configured to generate lights having a plurality of colors, the light source configured to be driven in a field sequential color driving method; and a display panel configured to receive the lights to display an image, display the colors at a first area in a first order, and display the colors at a second area different from the first area in a second order different from the first order.

First claim

What is claimed is:

1. A method of displaying an image, the method comprising:
driving a light source of a display panel in a field sequential color driving pattern to display the image, the light source generating light having a plurality of colors;
displaying the colors at a first area of the display panel in a first order, the first area comprising a first plurality of adjacent pixels; and
displaying the colors at a second area of the display panel in a second order different from the first order, the second area being different from the first area and comprising a second plurality of adjacent pixels,
wherein the image is a watermarking including information and the watermarking is displayed at the display panel when a movable object moves between a user and the display panel,
wherein the colors comprise a first color and a second color different from the first color,
wherein the displaying of the colors at the first area of the display panel in the first order comprises:
displaying the first color at the first area of the display panel during a first sub frame period of a frame period; and
displaying the second color at the first area of the display panel during a second sub frame period next to the first sub frame period of the frame period, and
wherein the displaying of the colors at the second area of the display panel in the second order comprises:
displaying the second color at the second area of the display panel during the first sub frame period; and
displaying the first color at the second area of the display panel during the second sub frame period.

2. The method of claim 1 , wherein the colors further comprise a black color different from the first color and the second color, and
wherein the displaying of the colors at the first area of the display panel in the first order comprises displaying the black color at the first area of the display panel during at least one of a last sub frame period or the first sub frame period of the frame period.

3. The method of claim 1 , wherein the colors further comprise a black color different from the first color and the second color, and
wherein the displaying of the colors at the second area of the display panel in the second order comprises displaying the black color at the second area of the display panel during at least one of a last sub frame period or the first sub frame period of the frame period.

4. The method of claim 1 , wherein the colors further comprise a white color different from the first color and the second color, and
wherein the displaying of the colors at the first area of the display panel in the first order comprises displaying the white color at the first area of the display panel during at least one of a last sub frame period or the first sub frame period of the frame period.

5. The method of claim 1 , wherein the colors further comprise a white color different from the first color and the second color, and
wherein the displaying of the colors at the second area of the display panel in the second order comprises displaying the white color at the second area of the display panel during at least one of a last sub frame period or the first sub frame period of the frame period.

6. The method of claim 1 , wherein the colors further comprise a third color different from the first color and the second color, the method further comprising:
displaying the colors at a third area different from the first area and the second area of the display panel in a third order different from the first order and the second order.

7. The method of claim 6 , wherein the displaying of the colors at the first area of the display panel in the first order comprises:
displaying the first color at the first area of the display panel during the first sub frame period of the frame period;
displaying the second color at the first area of the display panel during the second sub frame period next to the first sub frame period of the frame period; and
displaying the third color at the first area of the display panel during a third sub frame period next to the second sub frame period of the frame period.

8. The method of claim 7 , wherein the displaying of the colors at the second area of the display panel in the second order comprises:
displaying the second color at the second area of the display panel during the first sub frame period;
displaying the third color at the second area of the display panel during the second sub frame period; and
displaying the first color at the second area of the display panel during the third sub frame period.

9. The method of claim 8 , wherein the displaying of the colors at the third area of the display panel in the third order comprises:
displaying the third color at the third area of the display panel during the first sub frame period;
displaying the first color at the third area of the display panel during the second sub frame period; and
displaying the second color at the third area of the display panel during the third sub frame period.

10. A display apparatus comprising:
a light source configured to generate lights having a plurality of colors, the light source configured to be driven in a field sequential color driving method; and
a display panel configured to:
receive the lights to display an image;
display the colors at a first area in a first order, the first area comprising a first plurality of adjacent pixels; and
display the colors at a second area different from the first area in a second order different from the first order, the second area comprising a second plurality of adjacent pixels,

wherein the image is a watermarking including information and the display panel is further configured to display the watermarking when a movable object moves between a user and the display panel, and
wherein the colors comprise a black color, and the display panel is further configured to display the black color at the first area and the second area of the display panel during at least one of a last sub frame period or a first sub frame period of a frame period.

11. A display apparatus comprising:
a light source configured to generate lights having a plurality of colors, the light source configured to be driven in a field sequential color driving method; and
a display panel configured to:
receive the lights to display an image;
display the colors at a first area in a first order the first area comprising a first plurality of adjacent pixels; and
display the colors at a second area different from the first area in a second order different from the first order, the second area comprising a second plurality of adjacent pixels,
wherein the image is a watermarking including information and the display panel is further configured to display the watermarking when a movable object moves between a user and the display panel, wherein the colors comprise a white color, and
the display panel is further configured to display the white color at the first area and the second area of the display panel during at least one of a last sub frame period or a first sub frame period of a frame period.

12. The display apparatus of claim 10 , wherein the display panel is an organic light emitting display panel, and the light source comprises an organic light emitting diode in the organic light emitting display panel.
