Abstract

An apparatus, a method and a non-transitory computer readable medium is provided. The apparatus includes: at least one processor; and at least one memory storing computer program instructions configured, working with the at least one processor, to cause the apparatus to perform at least the following: detecting bending of a flexible auto-stereoscopic display comprising a parallax barrier arrangement; and compensating for movement of the parallax barrier arrangement, caused by the bending of the flexible auto-stereoscopic display, by adjusting one or more characteristics of the flexible auto-stereoscopic display in dependence upon the bending of the flexible auto-stereoscopic display.

First claim

We claim:

1. An apparatus, comprising:
at least one processor; and
at least one memory storing computer program instructions configured, working with the at least one processor, to cause the at least one processor to perform at least the following:
causing, by the at least one processor, a parallax barrier arrangement of a flexible auto-stereoscopic display to display a plurality of opaque regions defining a plurality of slits;
causing, by the at least one processor, a first plurality of pixels of a display panel of the flexible auto-stereoscopic display to display first image content for a first eye of a viewer and a second plurality of pixels of the display panel of the auto-stereoscopic display to display second image content for a second eye of the viewer, wherein the parallax barrier arrangement is arranged to conceal the first plurality of pixels from the second eye of the viewer and arranged to conceal the second plurality of pixels from the first eye of the viewer;
detecting, by the at least one processor, bending of the flexible auto-stereoscopic display;
determining that the bending of the flexible auto-stereoscopic display has caused a first portion of the first image content to become visible to the second eye of the viewer; and
responding to the determination that the first portion of the first image content has become visible to the second eye of the viewer, by adjusting one or more of the opaque regions of the parallax barrier arrangement, using the at least one processor, to change a size of at least one slit defined by adjacent opaque regions of the parallax barrier arrangement such that the first portion of the first image content is concealed from the second eye of the viewer.

2. The apparatus as claimed in claim 1 , wherein the one or more opaque regions of the parallax barrier arrangement are adjusted by the at least one processor in dependence upon the position of the parallax barrier arrangement following bending of the flexible auto-stereoscopic display, and the positions of the first and second eyes of the viewer.

3. The apparatus as claimed in claim 2 , wherein the positions of the first and second eyes of the viewer are determined using at least one image captured by one or more image sensors.

4. The apparatus as claimed in claim 1 , wherein adjustment of the one or more opaque regions of the parallax barrier arrangement by the at least one processor depends upon where the flexible auto-stereoscopic display is bent.

5. The apparatus as claimed in claim 1 , wherein adjustment of the one or more opaque regions of the parallax barrier arrangement by the at least one processor depends upon the extent to which the flexible auto-stereoscopic display is bent.

6. The apparatus as claimed in claim 1 , wherein the computer program instructions are configured, working with the at least one processor, to cause the apparatus to: adjust the brightness of one or more pixels of the flexible auto-stereoscopic display, using the at least one processor, after detecting bending of the flexible auto-stereoscopic display.

7. The apparatus as claimed in claim 1 , wherein the computer program instructions are configured, working with the at least one processor, to cause the apparatus to: adjust the hue of one or more pixels of the flexible auto-stereoscopic display, using the at least one processor, after detecting bending of the flexible auto-stereoscopic display.

8. The apparatus as claimed in claim 1 , wherein the computer program instructions are configured, working with the at least one processor, to cause the apparatus to: change how the first portion of the first image content is displayed by the flexible auto-stereoscopic display.

9. The apparatus as claimed in claim 1 , wherein the computer program instructions are configured, working with the at least one processor, to cause: the flexible auto-stereoscopic display to change from displaying a stereoscopic image to displaying a non-stereoscopic image, in response to further bending of the flexible auto-stereoscopic display.

10. The apparatus as claimed in claim 9 , wherein the computer program instructions are configured, working with the at least one processor, to cause: an output to be provided to the viewer, following the bending of the flexible auto-stereoscopic display, which is associated with the switch from the flexible auto-stereoscopic display displaying a stereoscopic image to the flexible auto-stereoscopic display displaying a non-stereoscopic image.

11. The apparatus as claimed in claim 1 , wherein the computer program instructions are configured, working with the at least one processor, to cause the at least one processor to further perform: determining that the bending of the flexible auto-stereoscopic display has caused a second portion of the first image content to become concealed from the first eye of the viewer; and responding to the determination that the second portion of the first image content has become concealed from the first eye of the viewer, by adjusting one or more opaque regions of the parallax barrier arrangement, using the at least one processor, to change a size of at least one slit defined by adjacent opaque regions of the parallax barrier arrangement such that the second portion of the first image content is visible to the first eye of the viewer.

12. A method, comprising:
causing, by at least one processor, a parallax barrier arrangement of a flexible auto-stereoscopic display to display a plurality of opaque regions;
causing, by the at least one processor, a first plurality of pixels of a display panel of the flexible auto-stereoscopic display to display first image content for a first eye of a viewer and a second plurality of pixels of the display panel of the auto-stereoscopic display to display second image content for a second eye of the viewer, wherein the parallax barrier arrangement is arranged to conceal the first plurality of pixels from the second eye of the viewer and arranged to conceal the second plurality of pixels from the first eye of the viewer;
detecting, by the at least one processor, bending of the flexible auto-stereoscopic display;
determining that the bending of flexible auto-stereoscopic display has caused a first portion of the first image content to become visible to the second eye of the viewer; and
responding to the determination that the first portion of the first image content has become visible to the second eye of the viewer, by adjusting one or more of the opaque regions of the parallax barrier arrangement, using the at least one processor, to change a size of at least one slit defined by adjacent opaque regions of the parallax barrier arrangement such that the first portion of the first image content is concealed from the second eye of the viewer.

13. The method as claimed in claim 12 , wherein the one or more opaque regions of the parallax barrier arrangement, are adjusted by the at least one processor in dependence upon the position of the parallax barrier arrangement following bending of the flexible auto-stereoscopic display, and the positions of the first and second eyes of the viewer.

14. A non-transitory computer readable medium storing computer program instructions that, when performed by at least one processor, cause at least the method of claim 12 to be performed.

15. The method as claimed in claim 12 , further comprising:
determining that the bending of flexible auto-stereoscopic display has caused a second portion of the first image content to become concealed from the first eye of the viewer; and
responding to the determination that the second portion of the first image co
