An LED (Light-Emitting Diode) is a small cell or conductor that glows and becomes illuminated when a voltage is applied to it.
The phrase 'LED display' is often used broadly to describe screens on a wide range of devices. This includes commercial and consumer technology such as TVs, mobile phones, and PC monitors.
These high-resolution LED displays tend to use highly dense diode arrays - often numbering in the thousands - to control illumination and colour cycling across millions of individual pixels. This allows for the rendering of highly detailed moving images at pixel densities of up to 4k and beyond.
However, in engineering component terms, the definition of an LED display is more commonly taken to be a discrete light-up readout board. Often relatively small and simple, they are designed to be attached to an instrument panel or mounted on a printed circuit board (PCB). The purpose of these types of LED displays is typically just to provide clear and concise information readout for the user.
Such LED displays are often designed around the classic segmented number format. Other more advanced models may use a range of alternative display styles and diode configurations, including popular versions sold with either dot matrix or light bar arrays.
