SYSTEM AND METHOD FOR DRIVING A LIGHT DELIVERY DEVICE
First Claim
Patent Images
1. A light delivery device comprising:
- a display device defining an optical path of light;
a system adapted to drive the display device with at least one predefined voltage intended to elicit at least one desired frequency of light from the display device;
a feedback device adapted to be positioned along the optical path of light;
wherein the system is adapted to receive information from the feedback device representing an actual frequency of light generated by the display device and to compare the actual frequency with the desired frequency to determine an offset; and
wherein the system is adapted to cause the display device to be driven based on the offset.

Abstract
A light delivery device defining an optical path with a feedback device is disclosed. The feedback device dispatches actual illumination characteristics of the light delivery device to a control system, which compares the actual illumination characteristics with desired illumination characteristics to determine an offset for driving the light delivery device.

15. A method for calibrating a display device, comprising:
-
positioning a feedback device along an optical path from the display;
reading illumination characteristics from the display device with the feedback device;
determining a desired frequency of light projected from the display device;
determining an actual frequency of light projected from the display device based on the illumination information;
determining an offset based on a difference between the desired frequency and the actual frequency; and
driving the display device based on the offset. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
