## Abstract

A stereoscopic image display device includes; a display device includes a plurality of pixels, and which displays a first image transmitted to a left eye and displays a second image transmitted to a right eye, wherein the display device displays the first image and the second image by inserting a third image representing a predetermined luminance between the first image transmitted to the left eye and the second image transmitted to the right eye.

## Claims

### Claim 1

A stereoscopic image display device comprising:
a display device which includes a plurality of pixels, and which displays a first image transmitted to a left eye and displays a second image transmitted to a right eye,
wherein the display device displays the first image and the second image by inserting a third image representing a predetermined luminance between the first image transmitted to the left eye and the second image transmitted to the right eye, and
wherein at least one overlapping pixel displays the same luminance in the first image transmitted to the left eye and in the second image transmitted to the right eye, and
at least one non-overlapping pixel displays different luminances in the first image transmitted to the left eye and in the second image transmitted to the right eye,
and the at least one overlapping pixel and the at least one non-overlapping pixel are respectively applied with different data voltages in order to display substantially the same luminance.

### Claim 2 (depends on 1)

The stereoscopic image display device of claim 1, wherein
the data voltages applied to the at least one non-overlapping pixel is applied by converting an input data into the data voltages after amending the input data.

### Claim 3 (depends on 2)

The stereoscopic image display device of claim 2, wherein
the data voltages applied to the at least one overlapping pixel is applied by converting the input data into the data voltage in a non-amended state.

### Claim 4 (depends on 1)

The stereoscopic image display device of claim 1, wherein
when data corresponding to a pixel of the plurality of pixels that is first displayed among the first image transmitted to the left eye and the second image transmitted to the right eye is referred to as a first data, and data that is displayed secondly is referred to as a second data, and
the second data is amended based on a luminance value of the first data and a luminance value of the second data and is converted into a data voltage to apply to the pixel.

### Claim 5 (depends on 4)

The stereoscopic image display device of claim 4, wherein
an amendment of the second data is executed to change a luminance of the pixel from a luminance of the third image to the luminance represented by the second data.

### Claim 6 (depends on 4)

The stereoscopic image display device of claim 4, wherein
the amendment of the second data is executed by a lookup table which stores an amended luminance value of the second data based on the luminance values of the first data and the second data.

### Claim 7 (depends on 4)

The stereoscopic image display device of claim 4, wherein
when the first data represents a low luminance and the second data represents a high luminance, the amended second data represents a higher luminance than the second data.

### Claim 8 (depends on 4)

The stereoscopic image display device of claim 4, wherein
when the first data represents the high luminance and the second data represents the low luminance, the amended second data represents a lower luminance than the second data.

### Claim 9 (depends on 1)

The stereoscopic image display device of claim 1, wherein
the predetermined luminance of the third image represents a black image.

### Claim 10 (depends on 1)

The stereoscopic image display device of claim 1, wherein
the first image transmitted to the left eye is applied to a pixel of the plurality of pixels as a left image data voltage and the second image transmitted to the right eye is applied to the pixel as a right image data voltage, the third image is applied to the pixel as an inserting data voltage, and
the pixel is applied with the data voltage in the sequence of the left image data voltage, the inserting data voltage, the right image data voltage, and the inserting data voltage, and
wherein the pixel is one of the at least one non-overlapping pixel and the at least one overlapping pixel.

### Claim 11 (depends on 10)

The stereoscopic image display device of claim 10, wherein
the predetermined luminance of the third image represents a black image.

### Claim 12 (depends on 10)

The stereoscopic image display device of claim 10, wherein
the inserting data voltage is a predetermined voltage representing a higher luminance than a black image.

### Claim 13 (depends on 10)

The stereoscopic image display device of claim 10, wherein
when a difference between the left image data voltage and the right image data voltage is more than a predetermined range, the inserting data voltage is applied with a voltage value representing a higher luminance than a black image.

### Claim 14 (depends on 13)

The stereoscopic image display device of claim 13, wherein
the inserting data voltage is determined to be the luminance represented by selecting the left image data voltage and the right image data voltage to be equally different from the inserting data voltage.

### Claim 15 (depends on 10)

The stereoscopic image display device of claim 10, wherein
when a gray represented by one of the left image data voltage and the right image data voltage is less than a maximum black gray, and a gray represented by the other of the left image data voltage and the right image data voltage is larger than a minimum white gray, the inserting data voltage is applied with a value representing the luminance higher than a black image.

### Claim 16 (depends on 15)

The stereoscopic image display device of claim 15, wherein
the inserting data voltage is determined to be the luminance represented by selecting the left image data voltage and the right image data voltage to be equally different from the inserting data voltage.

### Claim 17 (depends on 1)

The stereoscopic image display device of claim 1, wherein
a liquid crystal panel having a liquid crystal layer; and
a backlight unit.

### Claim 18 (depends on 1)

The stereoscopic image display device of claim 1, further comprising:
spectacles including a pair of lenses that are alternately turned on and off,
wherein the display device is synchronized to alternately display the image transmitted to the left eye and the image transmitted to the right eye and for the spectacles to alternately turn a lens on and off.

### Claim 19 (depends on 18)

The stereoscopic image display device of claim 18, wherein
the spectacles and the display device are synchronized via wireless communication.
