Abstract:
1. A method of compensation for non-uniform illumination from a light guide, comprising: determining a first portion of the light guide that provides greater light output relative to a second portion of the light guide when illuminated by a backlight; determining a first compensation pattern for generation on a liquid crystal display (LCD) to block light from the first portion relative to light from the second portion; incorporating the first compensation pattern into an image to be displayed on the LCD; and displaying the image with the incorporated first compensation pattern on the LCD, wherein the LCD is located about the light guide such that when the first compensation on pattern is generated on the LCD, the first compensation pattern aligns with the first and second portions to reduce the intensity of light passing through the first compensation pattern from the first portion realative to the intensity of light passing through the first compensation pattern from the second portion.
