Crystal LED (CLED) refers to a manufacturing technology of screens. It was invented by Sony and revealed at CES 2012.
This technology makes use of pixels mounted on each segment RGB of the display, such that each pixel is illuminated independently. This makes it the first “true” LED display.An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors in store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes.
