# Lighting and displays: Equipment and suppliers What sits inside an LED package, a screen and a laser Source page: https://www.materialinsights.org/energy/e_lighting/equipment/ What this tab covers For each method, the main pieces of equipment, who makes them (by region) and what they are made of (bill of materials). Key hardware: the LED package, its driver and the luminaire for lighting; the panel and backlight for displays; pump diodes and gain fibre for lasers. #### LED lighting **LED package**^[7](https://www.ledinside.com/node/view/32726)^[11](https://broker.zkb.ch/uploads/files/Conferences/2024/SEC/ams-OSRAM.pdf) Turns DC current into white light.
