Abstract

A two dimensional to three dimensional (2D-3D) convertible display device is disclosed. In one embodiment, the display device includes i) a first display unit configured to selectively output one of a composite image and backlight, wherein the composite image comprises a background image and a mask image, for an object, wherein the background image comprises element images for a background excluding the object and wherein the mask image is a white image which has the same shape as that of the object, ii) a lens unit configured to convert the composite image into a stereoscopic image or pass through the backlight and iii) a second display unit configured to output i) a two-dimensional (2D) image of the object by the use of the backlight at a 2D mode and ii) the combination of the 2D image and the composite image at a three dimensional (3D) mode.

Claims

1. A display device comprising:

a first display unit configured to selectively output one of a composite image and backlight, wherein the composite image comprises a background image and a mask image, for an object, wherein the background image comprises element images for a background excluding the object, and wherein the mask image is a white image which has the same shape as that of the object;

a lens unit configured to convert the composite image into a stereoscopic image or pass through the backlight; and

a second display unit configured to output i) a two-dimensional (2D) image of the object by the use of the backlight at a 2D mode and ii) the combination of the 2D image and the composite image at a three dimensional (3D) mode.

2. The display device of claim 1, further comprising a control unit configured to control the first display unit to selectively output the composite image or backlight based on one of the 2D and 3D modes.

3. The display device of claim 1, wherein the second display unit is a transmissive spatial light modulator (SLM).

4. The display device of claim 1, wherein the lens unit comprises one of a lens array and a lenslet array (micro lens array).

5. A display method comprising:

selectively outputting one of a composite image and backlight, wherein the composite image comprises a background image and a mask image, for an object, wherein the background image comprises element images for a background excluding the object, and wherein the mask image is a white image which has the same shape as that of the object;

converting the composite image into a stereoscopic image or passing through the backlight;

outputting a two-dimensional (2D) image of the object by the use of the backlight at a 2D mode; and

outputting the combination of the 2D image and the composite image at a three dimensional (3D) mode.

6. The display method of claim 5, wherein the converting is performed by one of a lens array and a lenslet array (micro lens array).

7. The display method of claim 5, wherein the outputting of the 2D image and the combination image is performed by a transmissive spatial light modulator (SLM).

8. A display device comprising:

means for selectively outputting one of a composite image and backlight, wherein the composite image comprises a background image and a mask image, for an object, wherein the background image comprises element images for a background excluding the object, and wherein the mask image is a white image which has the same shape as that of the object;

means for converting the composite image into a stereoscopic image or passing through the backlight;

means for means for outputting a two-dimensional (2D) image of the object by the use of the backlight at a 2D mode; and

means for outputting the combination of the 2D image and the composite image at a three dimensional (3D) mode.
