2. Diffuser (optics) - Wikipedia

   en.wikipedia.org/wiki/Diffuser_(optics)

   In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.

   The diffused light then travels to either side of the diffuser; the front faces the actual LCD panel, the back has a reflector to guide otherwise wasted light back toward the LCD panel. The reflector is sometimes made of aluminum foil or a simple white-pigmented surface.

   The light panels, part of the company's 'Smarter Series' of products, have smart capabilities (via WiFi) including app and voice commands, music sync and touch controls. The light panels are made with LED chips on a printed circuit board and feature a diffuser on a flat surface.

5. Liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_display

   A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]

6. Spectralon - Wikipedia

   en.wikipedia.org/wiki/Spectralon

   A Spectralon panel. Spectralon is a fluoropolymer that has the highest diffuse reflectance of any known material or coating over the ultraviolet, visible, and near-infrared regions of the spectrum. [1] It is the whitest substance available and reflects 99% of the light.

7. Laylight - Wikipedia

   en.wikipedia.org/wiki/Laylight

   [4] [5] When paired with a roof lantern or skylight on a sloped roof, a laylight functions as an interior light diffuser. [6] Before the advent of electric lighting, laylights allowed transmission of light between floors in larger buildings, and were not always paired with skylights.
