System and method for self-aligning collapsible display

1. A packaged display for shipment, comprising:

a first package having

a light engine for projecting an optical test image based on a digital test image; and

a second package having

a first mirror, when the display is unpackaged and assembled, positioned to reflect the optical test image onto a screen;

a feedback camera, when the display is unpackaged and assembled, positioned to capture at least a portion of the optical test image; and

electronics, communicatively coupled to the feedback camera, for comparing the captured image with the digital test image, and generating at least one of a focus or alignment adjustment based on the comparing so as to correct for mis-positioning of the first mirror or the light engine from assembly after shipment, the electronics further for remapping video data to correct for optical distortion based on the comparing;

wherein non-test images are interspersed with optical test images.

2. The display of claim 1 , wherein the second package further has a second mirror positioned to reflect the optical test image from the light engine onto the first mirror.

3. The display of claim 2 , wherein the alignment adjustment includes an alignment adjustment of the first or second mirror.

4. The display of claim 2 , further comprising actuators coupled to the first and second mirrors and wherein the electronics are further capable of transmitting the adjustment to at least one of the actuators.

5. The display of claim 1 , wherein the focus adjustment includes adjusting the focus of the light engine by either adjusting the position of the light engine or by adjusting the position of elements within the light engine.

6. The display of claim 1 , further comprising an actuator coupled to the light engine and wherein the alignment adjustment is sent to the actuator to align the light engine.

7. The display of claim 1 , wherein the electronics are activated when the display is powered on.

8. A packaged display for shipment, comprising:

a first package having

a light engine for projecting an optical test image based on a digital test image; and

a second package having

a first mirror, when the display is unpackaged and assembled, positioned to reflect the optical test image onto a screen;

a feedback camera, when the display is unpackaged and assembled, positioned to capture at least a portion of the optical test image; and

electronics, communicatively coupled to the feedback camera, for comparing the captured image with the digital test image, and generating at least one of a focus or alignment adjustment based on the comparing so as to correct for mis-positioning of the first mirror or the light engine from assembly after shipment, the electronics farther for remapping video data to correct for optical distortion based on the comparing;

wherein the electronics generates, in order, a focus adjustment, a remapping adjustment, and an alignment adjustment.

9. A packaged display for shipment, comprising:

a first package having

means for projecting an optical test image based on a digital test image; and

a second package having

means for reflecting the optical test image onto a screen;

means for capturing at least a portion of the optical test image;

means for comparing the captured image with the digital test image; and

means for generating at least one of a focus or alignment adjustment based on the comparing so as to correct for mis-positioning of the means for reflecting or the means for projecting from assembly after shipment and for remapping video data to correct for optical distortion based on results from the means for comparing;

wherein the means for projecting intersperses non-test images with optical test images.

10. A method for assembling a display after shipment, comprising:

assembling a display from two packages after shipment,

the first package having

a light engine; and

the second package having

a first mirror,

a feedback camera, and

electronics,

projecting an optical test image using the light engine based on a digital test image;

reflecting the optical test image with the first mirror onto a screen;

capturing at least a portion of the optical test image with the feedback camera;

comparing the captured image with the digital test image with the electronics;

generating at least one of a focus or alignment adjustment based on the comparing with the electronics so as to correct for mis-positioning of the first mirror or the light engine from assembly after shipment; and

remapping video data to correct for optical distortion based on the comparing;

wherein the projecting intersperses non-test images with optical test images.

11. The method of claim 10 , wherein the reflecting comprises reflecting the optical test image from a first mirror onto a second mirror and reflecting the optical test image from the second mirror onto the screen.

12. The method of claim 11 , wherein the alignment adjustment includes an alignment adjustment of the first or second mirror.

13. The method of claim 11 , wherein actuators are coupled to the first and second mirrors and the method further comprises transmitting the adjustment to at least one of the actuators.

14. The method of claim 10 , wherein the focus adjustment includes adjusting the focus of the light engine by either adjusting the position of a light engine that projects the optical test image or by adjusting the position of elements within the light engine.

15. The method of claim 10 , further comprising transmitting the alignment adjustment to an actuator coupled to the light engine to align the light engine.

16. The method of claim 10 , wherein the method is carried out within a display when the display is powered on.

17. A method for assembling a display after shipment, comprising:

assembling a display from two packages after shipment,

the first package having
