## Abstract

A display device includes: a display panel configured to display a first image having a first resolution; and a display panel driving circuit configured to drive the display panel, wherein the display panel driving circuit is configured to receive image data corresponding to a second image having a second resolution that is higher than the first resolution, to receive gaze data indicating a user's gaze, to select partial image data which reflects the user's gaze from the image data based on the gaze data, and to drive the display panel to display the first image based on the partial image data.

## Claims

### Claim 1

A display device comprising:
a display panel configured to display a first image having a first resolution; and
a display panel driving circuit configured to drive the display panel,
wherein the display panel driving circuit is configured to receive image data corresponding to a second image having a second resolution that is higher than the first resolution, to receive gaze data indicating a user's gaze, to select partial image data which reflects the user's gaze from the image data based on the gaze data, and to drive the display panel to display the first image based on the partial image data, wherein the display device is configured to maintain center coordinates of the first image in response to the gaze data indicating a movement of the user's gaze that is still inside a predetermined central region, and the display device is configured to adjust the center coordinates of the first image such that the first image is adjusted to move relative to the second image in a display area of the display panel such that a location of a high resolution region of a composite image formed by the first and second images is adjusted in response to the gaze data indicating a movement of the user's gaze to outside of the predetermined central region.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the display panel driving circuit is configured to select the partial image data to locate the user's gaze in the predetermined central region.

### Claim 3 (depends on 2)

The display device of claim 2, wherein horizontal center coordinates of the partial image data are determined as the user's gaze moves in a horizontal direction on the display panel.

### Claim 4 (depends on 3)

The display device of claim 3, wherein the horizontal center coordinates do not move when the user's gaze is located in the predetermined central region.

### Claim 5 (depends on 4)

The display device of claim 4, wherein the horizontal center coordinates move to the left when the user's gaze moves to the left beyond the predetermined central region.

### Claim 6 (depends on 4)

The display device of claim 4, wherein the horizontal center coordinates move to the right when the user's gaze moves to the right beyond the predetermined central region.

### Claim 7 (depends on 2)

The display device of claim 2, wherein vertical center coordinates of the partial image data are determined as the user's gaze moves in a vertical direction on the display panel.

### Claim 8 (depends on 7)

The display device of claim 7, wherein the vertical center coordinates do not move when the user's gaze is located in the predetermined central region.

### Claim 9 (depends on 8)

The display device of claim 8, wherein the vertical center coordinates move upwardly when the user's gaze moves upwardly beyond the predetermined central region.

### Claim 10 (depends on 8)

The display device of claim 8, wherein the vertical center coordinates move downwardly when the user's gaze moves downwardly beyond the predetermined central region.

### Claim 11

A display system comprising:
a display device configured to output a first image having a first resolution;
a gaze detecting sensor configured to detect a user's gaze to generate a gaze detection signal;
a processing unit configured to generate gaze data indicating the user's gaze based on the gaze detection signal; and
a graphic processing unit configured to generate image data corresponding to a second image having a second resolution that is higher than the first resolution,
wherein the display device is configured to receive the gaze data from the processing unit, to receive the image data from the graphic processing unit, and to output the first image by reflecting the user's gaze based on the gaze data and the image data,
wherein the display device is configured to maintain center coordinates of the first image in response to the gaze data indicating a movement of the user's gaze that is still inside a predetermined central region, and the display device is configured to adjust the center coordinates of the first image such that the first image is adjusted to move relative to the second image in a display area of the display device such that a location of a high resolution region of a composite image formed by the first and second images is adjusted in response to the gaze data indicating a movement of the user's gaze to outside of the predetermined central region.

### Claim 12 (depends on 11)

The display system of claim 11, wherein the display device is configured to provide information relating to the gaze data or information relating to the user's gaze which the first image reflects to the graphic processing unit.

### Claim 13 (depends on 11)

The display system of claim 11, wherein the display device includes:
a display panel configured to display the first image; and
a display panel driving circuit configured to receive the image data, to receive the gaze data, to select partial image data which reflects the user's gaze from the image data based on the gaze data, and to drive the display panel to display the first image based on the partial image data.

### Claim 14 (depends on 13)

The display system of claim 13, wherein the display panel driving circuit is configured to select the partial image data to locate the user's gaze in a central region of the first image.

### Claim 15 (depends on 14)

The display system of claim 14, wherein horizontal center coordinates of the partial image data are determined as the user's gaze moves in a horizontal direction on the display panel.

### Claim 16 (depends on 15)

The display system of claim 15, wherein the horizontal center coordinates do not move when the user's gaze is located in the predetermined central region.

### Claim 17 (depends on 16)

The display system of claim 16, wherein the horizontal center coordinates move to the left when the user's gaze moves to the left beyond the predetermined central region, and
wherein the horizontal center coordinates move to the right when the user's gaze moves to the right beyond the predetermined central region.

### Claim 18 (depends on 14)

The display system of claim 14, wherein vertical center coordinates of the partial image data are determined as the user's gaze moves in a vertical direction on the display panel.

### Claim 19 (depends on 18)

The display system of claim 18, wherein the vertical center coordinates do not move when the user's gaze is located in the predetermined central region.

### Claim 20 (depends on 19)

The display system of claim 19, wherein the vertical center coordinates move upwardly when the user's gaze moves upwardly beyond the predetermined central region, and
wherein the vertical center coordinates move downwardly when the user's gaze moves downwardly beyond the predetermined central region.
