Abstract:
1. A light outputting arrangement, comprising: a light guide; a liquid crystal display (LCD); a light source for illuminating the light guide wherein any bright spots of an output light pattern from the light guide are compensated to effect a uniform output light pattern; a layer in proximity to the light guide to provide the compensation to effect a uniform output light pattern, the layer having a first area of a first transmissivity and a second area of a second transmissivity; a stored representation of a first compensation pattern to block light from the first area relative to light from the second area; a first module to incorporate the stored representation into an image to be displayed on the LCD; and a second module to generate the image with the stored representation for display on the LCD, wherein the first compensation pattern is generated such that it aligns with the first and second areas to reduce intensity of light passing through the first compensation pattern from the first area relative to the intensity of light passing through the first compensation pattern from the second area.
