DMX512 was developed in the late 1980s as a standard protocol for lighting consoles to communicate with dimmers, but has since been used for more complex applications, including the control of intelligent lighting fixtures.

The most common types of SMD are: 3528, single colour, non-addressable, very low power; 5050, containing three LEDs allowing for RGB and addressable strips as well as higher power levels; 2835, a newer single-color SMD having the same surface dimensions as the 3528 but a larger emitter area and a thinner design with an integrated heatsink ...
Views of a liquid-crystal display, both with electroluminescent backlight switched on (top) and switched off (bottom). A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel.
Hearing aid users can use a telecoil (T) switch to hear announcements directly through their hearing aid receiver.
