Adjusting a brightness level of a side emitting backlight display device using light spreading profiles

摘要

Embodiments of methods, systems, or apparatuses relating to adjusting a brightness level of at least one luminescent body disposed, at least in part, on a side emitting backlight display device are disclosed. In a particular embodiment, for example, one or more values representing a light spreading profile for a particular luminescent body may be accessed. A process, system, or apparatus may adjust a brightness of a particular luminescent body by adjusting one or more brightness values associated with that particular luminescent body based, at least in part, on the accessed values.

主权项

1. A method, comprising:
accessing a plurality of values representing a light spreading profile for a particular luminescent body, wherein said particular luminescent body is disposed as part of a side emitting backlight of a display device, and wherein said light spreading profile is operable for showing light distribution characteristics of light emitted from said particular luminescent body; determining a brightness value associated with said particular luminescent body by filtering one or more image characteristic values of an input image through at least one light spreading profile weighting function determined based, at least in part, on said plurality of accessed values representing said light spreading profile, said light spreading profile being used to determine a backlight level for said particular luminescent body; controlling said brightness value associated with said particular luminescent body based on said determined brightness value associated with said particular luminescent body; determining a truncated area of an input image according to a predetermined percentage of intensity value of said light spreading profile of said particular luminescent body; dividing said input image within said truncated area into a plurality of sub-image blocks; determining a plurality of representative values associated with said plurality of sub-image blocks; determining said brightness value associated with said particular luminescent body according to said plurality of representative values and said light spreading profile, said determining said brightness value associated with said particular luminescent body comprising;
applying a first matrix of said representative values to a second matrix determined based on said plurality of accessed values representing a light spreading profile of said particular luminescent body; andselecting a maximal value of said determined brightness value as said brightness value.
