Abstract

Techniques for using variable flower assemblies to control light leakage between designated portions of light-emitting elements are provided. In some embodiments, a variable flower assembly comprises a plurality of light-transmissive segments each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element mounted on a first plane. A first edge of each of the light-transmissive segments collectively surrounds the light-emitting element on a second plane substantially parallel to the first plane. A second opposing edge of each of the light-transmissive segments collectively forms an opening of the tube. In some embodiments, a reflective assembly which reflectance level is electronically controllable may surround the variable flower assembly.

First claim

What is claimed is:

1. A variable backlight flower assembly for a display system comprising:
a plurality of light-transmissive segments each configured to be set to an individual light-transparency level based on electronic controls coupled to the plurality of light-transmissive segments;
wherein the plurality of light-transmissive segments physically forms walls of a tube around a light-emitting element, wherein the light-emitting element is configured to illuminate a first pla…
