Abstract

Operating systems are described that interface applications and display screens capable of displaying two-dimensional and three-dimensional content. In one aspect, an operating system includes an application programming interface (API), a display driver interface, and a display driver. The API enables one or more applications to deliver requests that define a screen region and either a two-dimension indicator or a three-dimension indicator. The display driver interface passes configuration commands corresponding to the requests. The display driver is associated with a display screen. The display driver receives the configuration commands and responds by generating screen control signals to adjust the display screen to support the screen region.

Claims

1. A method used in an operating system to support simultaneous display on a screen of both two-dimensional content and three-dimensional content, the method comprising:

receiving from a first application a first command directing display of the two-dimensional content within a first region of the screen;

responding to the first command by sending a first control signal that places the screen in a two-dimensional mode within the first region;

receiving from a second application a second command directing display of the three-dimensional content within a second region of the screen; and

responding to the second command by sending a second control signal that places the screen in a three-dimensional mode within the second region.

2. The method of claim 1, further comprising receiving user input directing movement of the three-dimensional content from the second region of the screen to a third region of the screen, and sending a third control signal directing the movement via corresponding modifications to the screen.

3. The method of claim 1, further comprising delivering three-dimensional content to a pixel array of the screen that corresponds with the second region of the screen in which an adaptable light manipulator of the screen is operating in the three-dimensional mode.

4. The method of claim 1, wherein the first command and second command are part of an application program interface.

5. The method of claim 1, further comprising:

receiving an input signal from a user input interface;

generating a third control signal in response to the input signal, the third control signal relating to a three-dimensional characteristic; and

delivering the third control signal to cause the adjustment of the three-dimensional characteristic of the three-dimensional content being displayed within the second region of the screen.

6. The method of claim 1, further comprising:

receiving an indication from the screen of whether the second control signal was successful;

generating a response to the second command based on the indication; and

providing the response to the second application.

7. The method of claim 6, wherein said providing comprises:

providing a window handle in the response to the second application, the window handle being a handle for a window opened in the second region to display the three-dimensional content.

8. The method of claim 1, wherein the second command includes one or more parameters, wherein said receiving comprises:

generating the second control signal to configure the screen based on the one or more parameters.

9. The method of claim 8, wherein the second command is configured to cause a window that displays the three-dimensional content to be opened in the second region.

10. The method of claim 8, wherein said generating comprises:

filtering out a parameter of the one or more parameters that is incompatible with the screen.

11. The method of claim 1, further comprising:

receiving a request from the second application for an indication of at least one characteristic of the screen; and

providing the requested indication of the at least one characteristic to the second application.

12. An operating system that supports a plurality of software applications and at least one of a plurality of screens, a first of the plurality of screens supporting at least three-dimensional display, and a second of the plurality of screens supporting at least two-dimensional display, the operating system comprising:

an application programming interface through which a first of the plurality of software applications can deliver at least one request that defines a first screen region and either a two-dimension indicator or a three-dimension indicator;

a display driver interface through which at least one configuration command corresponding to the at least one request is passed; and

a first display driver, associated with the first screen of the plurality of screens, that receives the at least one configuration command and responds by generating one or more screen control signals to adjust the first screen to support the first screen region of the first of the plurality of screens.

13. The operating system of claim 12, wherein the at least one configuration command causes the display driver to manipulate incoming pixel data before delivery to the plurality of screens.

14. The operating system of claim 12, further comprising a second display driver, associated with the second of the plurality of screens, that receives and responds to the at least one configuration command by translating incoming three-dimensional data to two-dimensional data for display on the second screen of the plurality of screens.

15. The operating system of claim 12, wherein the display driver is configured to receive an indication from the first screen of whether a screen control signal was successful, to generate a response to the at least one request that includes the indication, and to transmit the response to the first application via the application programming interface.

16. The operating system of claim 12, wherein a first request of the at least one request defines the first screen region, and includes the three-dimension indicator and one or more parameters.

17. The operating system of claim 16, wherein the first request is configured to cause a window that displays three-dimensional content to be opened in the first screen.

18. The operating system of claim 16, wherein the display driver interface is configured to filter out a parameter of the one or more parameters that is incompatible with the first screen.

19. The operating system of claim 16, wherein the first request is an open window command, and the one or more parameters includes at least one of a window size parameter, a window position parameter, a display resolution parameter, a window type parameter, a three-dimensional display type parameter, or a three-dimensional content source indication parameter.

20. The operating system of claim 12, further comprising:

a user input interface configured to receive a user input directed to three-dimensional content displayed in the first screen region, to generate a second configuration command based on the user input, the second configuration command being configured to adjust a three-dimensional characteristic of three-dimensional content displayed by the first screen region, the display driver interface being configured to pass the second configuration to the first display driver, the first display driver receiving the generated configuration command and generating a screen control signal to adjust the three-dimensional characteristic of the three-dimensional content being displayed within the first screen region.
