Abstract

A head mounted display device includes a first flexible display to display a left-eye image, a second flexible display to display a right-eye image, a first optical system between the first flexible display and a left eye of a user, a second optical system between the second flexible display and a right eye of the user, and a housing including the first flexible display, the second flexible display, the first optical system, and the second optical system.

First claim

What is claimed is:

1 . A head mounted display device, comprising:
a first flexible display to display a left-eye image; a second flexible display to display a right-eye image; a first optical system between the first flexible display and a left eye of a user; a second optical system between the second flexible display and a right eye of the user; and a housing including the first flexible display, the second flexible display, the first optical system, and the second optical system.

2 . The device as claimed in claim 1 , further comprising:
a curvature changer to change a curvature of at least one of the first flexible display or the second flexible display.

3 . The device as claimed in claim 2 , wherein a three-dimensional image is implemented by displaying the left-eye image in a manner different from the right-eye image.

4 . The device as claimed in claim 3 , further comprising:
a depth analyzer to analyze the left-eye image and the right-eye image and to output a depth value, wherein the curvature changer is to change the curvature of at least one of the first flexible display or the second flexible display based on the depth value.

5 . The device as claimed in claim 4 , wherein the curvature changer is to decrease the curvature of at least one of the first flexible display or the second flexible display for a first value of the depth value and is to increase the curvature of at least one of the first flexible display or the second flexible display for a second value of the depth value which is greater than the first value of the depth value.

6 . The device as claimed in claim 4 , wherein:
the depth analyzer is to output a plurality of depth values corresponding to a plurality of configuration objects in the left-eye image and the right-eye image, the curvature changer includes a plurality of micro actuators, and the micro actuators which correspond to the configuration objects are to change the curvature of at least one of the first flexible display or the second flexible display based on the depth values.

7 . The device as claimed in claim 6 , wherein the micro actuators are arranged on a substrate included in the first flexible display and a substrate included in the second flexible display in a matrix form.

8 . A head mounted display device, comprising:
a flexible display to display a left-eye image on a left-eye pixel and a right-eye image on a right-eye pixel; an optical system between both eyes of a user and the flexible display, the optical system to separate the left-eye image and the right-eye image from each other for projection to corresponding eyes of the user; and a housing including the flexible display and the optical system.

9 . The device as claimed in claim 8 , further comprising:
a curvature changer to change a curvature of the flexible display.

10 . The device as claimed in claim 9 , further comprising:
a depth analyzer to analyze the left-eye image and the right-eye image and to output a depth value of the image, wherein the curvature changer is to change the curvature of the flexible display based on the depth value.

11 . The device as claimed in claim 10 , wherein:
the curvature changer is to decrease the curvature of the flexible display for a first value of the depth value and to increase the curvature of the flexible display for a second value of the depth value, wherein the second value is greater than the first value.

12 . The device as claimed in claim 8 , wherein the optical system includes a lenticular lens or a parallax barrier.

13 . A head mounted display device, comprising:
a flexible display to time-divide and display a left-eye image and a right-eye image; an optical system to block sight of a right eye of a user during a period in which the left-eye image is displayed and to block sight of a left eye of the user during a period in which the right-eye image is displayed; and a housing including the flexible display and the optical system.

14 . The device as claimed in claim 13 , further comprising:
a curvature changer to change a curvature of the flexible display.

15 . The device as claimed in claim 14 , further comprising:
a depth analyzer to analyze the left-eye image and the right-eye image and to output a depth value of the image, wherein the curvature changer is to change the curvature of the flexible display based on the depth value.

16 . The device as claimed in claim 15 , wherein the curvature changer is to decrease the curvature of the flexible display for a first value of the depth value and to increase the curvature of the flexible display for a second value of the depth value, the second value greater than the first value.

17 . The device as claimed in claim 13 , wherein the optical system includes a shutter.

18 . A head mounted display device, comprising:
a flexible display to output left-eye and right-eye images; a depth analyzer to generate a depth value based on the left-eye and right-eye images; and an adjuster to change the flexible display based on the depth value.

19 . The device as claimed in claim 18 , wherein the adjuster is to change a curvature of the flexible display based on the depth value.

20 . The device as claimed in claim 19 , wherein the adjuster is to decrease the curvature of the flexible display for a first value of the depth value and to increase the curvature of the flexible display for a second value of the depth value, wherein the second value is greater than the first value.
