LED Displays

LED displays are small displays, lit by an LED (light emitting diode), which are designed to be mounted to a panel or PCB.

Features
LED displays are available in a range of different sizes, styles and colours. They are also available in surface mounted (SMD) or through-hole packages.

Types of LED display:

• Segmented Displays (for example 7-segment and 14-segment) consist of sections which, when lit, create numbers and/or letters. You would find 7-segment displays in calculators and digital alarm clocks.
• Dot Matrix consist of multiple dots which, when lit, create numbers, letters, symbols and images. The higher the number of dots, the more detailed symbols you can create. More basic dot matrix displays are ideal for message boards.
• Light Bars consist of single or multiple sections that light up. They are usually square or rectangular and used for status indicators or to highlight icons on a display.

Uses
They can remain a small individual display or be used as part of a larger display. LED displays provide interaction between a user and system. Common uses for LED displays are basic information signage and household devices.
