Abstract

Various display control methods and apparatuses are provided. A method comprises inclining at least one display unit relative to an initial normal thereof to change a ratio of pixels distributed along two directions in each effective display region of the at least one display unit of a display system, wherein light emitted by each pixel in the effective display region of each display unit in the at least one display unit is transmitted to a visual angle range by a lens corresponding to the display unit in the display system, and the two directions comprise a first direction and a second direction parallel with the display unit and orthogonal with each other; and displaying a content to be displayed by the changed display system. Accordingly, differentiated display of visual angle information of two mutually orthogonal different directions can be realized.

First claim

What is claimed is:

1 . A method, comprising:
inclining, by a system comprising a processor, at least one display unit relative to an initial normal of the at least one display unit to change a ratio of pixels distributed along two directions in each effective display region of the at least one display unit of a display system resulting in a changed display system, wherein light emitted by each pixel in each effective display region of each display unit in the at least one display unit is transmitted according to a visual angle range by each lens corresponding to each display unit in the display system, and the two directions comprise a first direction and a second direction that are parallel with the at least one display unit and orthogonal with each other; and displaying content to be displayed by the changed display system.

2 . The method of claim 1 , wherein the display system comprises a light field display, wherein the light field display comprises a display array and a sub-lens array, which are arranged in sequence, wherein the sub-lens array comprises a plurality of lenses in a first array distribution, and wherein the display array comprises a plurality of display units in a second array distribution.

3 . The method of claim 2 , wherein multifunctional visual angle information of at least one object in the content is respectively displayed by a plurality of pixels of one of the at least one display unit.

4 . The method of claim 2 , wherein multifunctional visual angle information of at least one object in the content is respectively displayed by at least two of the at least one display unit.

5 . The method of claim 1 , wherein the display system comprises a display array, wherein the display array comprises a plurality of displays in array distribution, and wherein a display of the plurality of displays comprises a display unit of the at least one display unit, and a lens arranged in sequence.

6 . The method of claim 5 , wherein multifunctional visual angle information of at least one object in the content is respectively displayed by a plurality of lenses.

7 . The method of claim 1 , wherein the inclining comprises:
inclining each display unit of the at least one display unit by an angle relative to the first direction to change a shape of each effective region of the at least one display unit, thereby increasing a quantity of pixels distributed along the first direction in each effective region of the at least one display unit.

8 . The method of claim 7 , wherein an effective region with a changed shape is an oval of which a long axis is parallel with the first direction.

9 . The method of claim 7 , wherein at least one of an inclining direction or an inclining angle of at least two display units in the display system relative to the first direction are different.

10 . The method of claim 7 , wherein at least one of an inclining direction or an inclining angle of at least two display units in the display system relative to the first direction are same.

11 . The method of claim 7 , wherein at least two display units in the display system are opposite in inclining direction and same in inclining angle relative to the first direction.

12 . The method of claim 1 , further comprising:
before the displaying the content to be displayed by the changed display system, rotating the at least one display unit around a normal of the at least one display unit to increase a maximal quantity of pixels allowed to be changed along the first direction in each effective region of the at least one display unit.

13 . The method of claim 1 , further comprising: before the displaying the content to be displayed by the changed display system, increasing each effective region of the at least one display unit.

14 . The method of claim 13 , wherein the increasing each effective region of the at least one display unit comprises:
translating the at least one display unit along an initial normal direction of each display unit of the at least one display unit to increase each effective region of the at least one display unit.

15 . The method of claim 13 , wherein the increasing each effective region of the at least one display unit comprises:
respectively moving at least one lens along an optical axis direction of the at least one lens corresponding to the at least one display unit to increase each effective region of the at least one display unit.

16 . The method of claim 13 , wherein the increasing each effective region of the at least one display unit comprises:
adjusting an optical parameter of at least one lens respectively corresponding to the at least one display unit to increase each effective region of the at least one display unit.

17 . The method of claim 1 , further comprising: before the inclining the at least one display unit relative to the initial normal, determining the first direction.

18 . The method of claim 17 , wherein the determining the first direction comprises:
determining a horizontal direction vertical to the initial normal of the at least one display unit as the first direction.

19 . The method of claim 17 , wherein the determining the first direction comprises:
determining a vertical direction vertical to the initial normal of the at least one display unit as the first direction.

20 . The method of claim 17 , wherein the determining the first direction comprises:
determining the first direction according to a size of the display system.

21 . The method of claim 17 , wherein the determining the first direction comprises:
determining the first direction according to moving information of the display system.

22 . The method of claim 17 , wherein the determining the first direction according to the moving information of the display system comprises:
determining a reference direction corresponding to the moving information of the display system as the first direction according to a mapping relation between the moving information of the display system and the reference direction.

23 . An apparatus, comprising:
a memory that stores executable modules; and a processor, coupled to the memory, that executes or facilitates execution of the executable modules, the executable modules comprising: an inclining control module configured to incline at least one display unit relative to an initial normal thereof to change a ratio of pixels distributed along two directions in each effective display region of the at least one display unit of a display system resulting in a changed display system, wherein light emitted by each pixel in each effective display region of each display unit in the at least one display unit is transmitted to a visual angle range by a lens corresponding to a display unit of the at least one display unit in the display system, and the two directions comprise a first direction and a second direction parallel with the at least one display unit and orthogonal with each other; and a display control module configured to display content to be displayed by the changed display system.

24 . The apparatus of claim 23 , wherein the display system comprises a light field display, the light field display comprises a display array and a sub-lens array, which are arranged in sequence, the sub-lens array comprises a plurality of lenses in a first array distribution, and the display array comprises a plurality of display units in a second array distribution.
