An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may have three individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected ...
A first dynamic "local dimming" LED backlight was public demonstrated by BrightSide Technologies in 2003, [33] and later commercially introduced for professional markets (such as video post-production). [34] Edge LED lighting was first introduced by Sony in September 2008 on the 40-inch (1,000 mm) BRAVIA KLV-40ZX1M (known as the ZX1 in Europe ...
[14] [15] Sony has adapted quantum dot technology from the US company QD Vision [16] to introduce LCD TVs with an improved edge-lit LED backlight marketed under the term Triluminos in 2013. With a blue LED and optimized nanocrystals for green and red colors in front of it, the resulting combined white light allows for an equivalent or better ...
OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [35] while OLED can use more than three times as much power to display a mostly white image compared to an LCD. [36] Environmental influences
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.
