Abstract

A portable electronic device (200) including a housing having a movable housing portion in the form of a flip, rotating blade or slider portion. A controller is electrically coupled to a plurality of light shutter portions in the movable housing portion, wherein the controller independently configuring each light shutter portion between first and second light transmitting states based upon input from a sensor, an application or based upon the configuration of the housing. The shutter portions may obscure or reveal an underlying display or inputs.

Claims

1. A portable electronic device comprising:

a housing;

a movable housing portion positionable between first and second configurations;

the movable housing portion including a plurality of light shutter portions,

a controller electrically coupled to the plurality of light shutter portions,

the controller independently configuring each light shutter portion between first and second states,

wherein the first state permits light transmission through the movable housing portion and the second state obstructs the transmission of light through the movable housing portion.

2. The device of claim 1,

a shutter controlling sensor electrically coupled to the controller, the controller causing at least some of the shutter portions to change states in response to a signal from the shutter controlling sensor,

the shutter controlling sensor selected from a group comprising:

a proximity sensor, a tactile-based sensor, and an accelerometer detecting an orientation of the portable electronic device.

3. The device of claim 1, the controller causing at least some of the shutter portions to change states in response to a signal from an application running on the device.

4. The device of claim 1,

the movable housing portion covers at least a portion of the housing in a least one configuration,

at least a portion of the housing is concealed by at least one of the shutter portions configured in the light obstructing state when the movable housing portion covers at least a portion of the housing,

at least a portion of the housing is revealed through at least one of the shutter portions configured in the light transmitting state when the movable housing portion covers at least a portion of the housing.

5. The device of claim 1,

a user interface on the housing, the user interface selected from a group comprising a display and an input key,

the movable housing portion covers at least a portion of the user interface on the housing in a least one configuration,

the controller configuring the plurality of light shutter portions to conceal and reveal select portions of the user interface on the housing when the movable housing portion covers the select portions of the user interface.

6. The device of claim 5,

the user interface on the housing includes a display and an input key,

the movable housing portion covers at least a portion of the display and the input key,

the controller configuring the plurality of light shutter portions to conceal the input key and to reveal at least a portion of the display.

7. The device of claim 5,

the user interface on the housing includes a display and an input key,

the movable housing portion covers at least a portion of the display and the input key,

the controller configuring the plurality of light shutter portions to reveal the input key and to conceal at least a portion of the display.

8. The device of claim 1,

a user interface on the movable housing portion,

a display on the housing,

the movable housing portion covers at least a portion of the display on the housing in a least one configuration,

the controller capable of configuring the plurality of light shutter portions to reveal at least a portion of the display on the housing when the movable housing portion covers the revealed portion of the display,

the revealed portion of the display on the housing includes indicia for the user interface on the movable housing portion when the movable housing portion covers the revealed portion of the display.

9. The device of claim 1,

a user interface on the movable housing portion, the user interface electrically coupled to the controller,

a second user interface on the housing,

the movable housing portion covers at least a portion of the second user interface on the housing in a least one configuration,

the controller configuring the plurality of light shutter portions to conceal at least a portion of the second user interface on the housing when the movable housing portion covers the concealed portion of the second user interface,

the controller configuring the user interface to perform a function performed by the portion of the second user interface concealed.

10. The device of claim 1, the controller configuring the state of each of the light shutter portions dependent on the configuration of the movable housing portion.

11. The device of claim 10,

the first configuration of the movable housing portion is an opened configuration and the second configuration of the movable housing portion is a closed configuration,

the controller configuring the plurality of light shutter portions in the light obstructing state when the movable housing portion is in the opened configuration.

12. The device of claim 10,

the first configuration of the movable housing portion is an opened configuration and the second configuration of the movable housing portion is a closed configuration,

the controller configuring the plurality of light shutter portions to display an image when the movable housing portion is in the opened configuration.

13. The device of claim 1,

an image capture device including a lens focused on an image sensor communicably coupled to an image engine,

the controller configuring the plurality of light shutter portions to display a view finder aligned with an optical path of the lens when the movable housing portion is in the opened configuration.

14. The device of claim 1, an optical film disposed adjacent the plurality of light shutters on the movable housing portion, wherein an image viewable on the movable housing portion is not visible beyond a specified angle at which the image is projected through the optical film.
