Abstract

Backlight manufacturers provide product literature that furnish information about how bright their backlights are, with how little power they draw. There are enough variations in the application of luminance enhancement films which make it very difficult to compare backlights. The variation in light distribution angles of these films further complicates the system design when they do not match the viewing angle requirements of the target display. Measurements made with an integrating sphere and a photometer can be used to compare backlights directly. This paper provides data based on these measurements and suggestions to better estimate backlight power requirements from the display's viewing angle specifications.
