Abstract
A display and method enable the auto-alignment and auto focus of an image onto a large screen in a projection display.
Claims17
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.

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.

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.
