Transparent display backlight assembly

摘要

In embodiments of a transparent display backlight assembly, a backlight panel is operable as a transparent panel, and a light source generates light that the backlight panel directs from the light source to illuminate a display panel of a display device. Light refraction features refract and scatter the light, where the light refraction features are spaced for approximate transparency of the backlight panel and to illuminate the display panel. An active diffuser can be implemented as an additional transparent panel and operable for activation to diffuse the light from the backlight panel that illuminates the display panel.

主权项

1. A backlight assembly, comprising:
a light source configured to generate light; a display panel including a color filter system and configured for a percentage of transparency that permits an environment behind the backlight assembly to be viewed through the backlight assembly; a backlight panel configured for a percentage of transparency that permits an environment behind the backlight assembly to be viewed through the backlight assembly and configured to direct the light from the light source to illuminate the display panel; a multi-mode panel of the backlight assembly comprising an active shutter that provides variable light transmissivity based at least in part on an applied voltage and configured to prevent a section of the environment from being viewed through the backlight assembly; and light refraction features configured to refract and scatter the light, the light refraction features spaced for a percentage of transparency that permits an environment behind the backlight assembly to be viewed through the backlight assembly and to refract the light to illuminate the display panel.
