LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have enabled making devices with ever-shorter wavelengths, emitting light in a variety of colors. LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface.
The use of "turtle-safe lighting" LEDs that emit only at narrow portions of the visible spectrum is encouraged by conservancy groups in order to reduce harm. [131] Use in winter conditions: Since they do not give off much heat in comparison to incandescent lights, LED lights used for traffic control can have snow obscuring them, leading to ...
LED film, also called LED-embedded light film [1] is a new technology of surface-mount light-emitting diodes (LEDs) on flexible transparent conductive polymer films. This technology is based on the use of a cold curing pick-and-place process on transparent conductive plastics. [2] [3]
Other Sony products to feature OLED screens include the MZ-RH1 portable minidisc recorder, released in 2006 [214] and the Walkman X Series. [ 215 ] At the 2007, Las Vegas Consumer Electronics Show (CES), Sony showcased a 11-inch (28 cm), (resolution 960×540) and 27-inch (69 cm), full HD resolution at 1920 × 1080 OLED TV models. [ 216 ]
On-set virtual production (OSVP) [a] is an entertainment technology for television and film production in which LED panels are used as a backdrop for a set, on which video or computer-generated imagery can be displayed in real-time.
The PhlatLight LEDs are also used in a new class of ultra-compact DLP front projector commonly referred to as a "pocket projector" and have been introduced in new models from LG Electronics (HS101), Samsung (SP-P400) and Casio (XJ-A series). Home Theater projectors will be the next category of DLP projectors that will use PhlatLight LED technology.

Detail view of an LED display with a matrix of red, green and blue diodes The 1,500-foot (460 m) long LED display on the Fremont Street Experience in Downtown Las Vegas, Nevada, is currently the largest in the world. A LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) as pixels for a video display.
