LEDs - Spacers, StandoffsDisplay modules, LED drivers, and display drivers are electronic devices that are used to control and power displays, such as those found on smartphones, laptops, and TVs. LEDs, or light-emitting diodes, are small, solid-state devices that convert electrical energy into light. Spacers and standoffs are mechanical components that are used to mount LEDs in a circuit or on a PCB. Spacers are short, cylindrical components that are used to provide a fixed distance between two surfaces, such as between an LED and a PCB. Standoffs are longer, cylindrical components that are used to support and mount an LED, often above a PCB. These components are an important part of LED lighting and display systems, as they help to properly position and secure the LEDs.
