The Light Pen is an input device that is very widely used in modern day. It is quite similar with the technology of touch screen. And of course, it is possible to use a light pen with LED monitor screens, yet there are separate LED light pen versions available for this task.

Actually, light pen better option for designing work than a mouse since it has more positional accuracy. Light pens are mostly battery charging based.

A light pen is a light-sensitive input device used on computers similar to a stylus. It is used to select text, draw pictures or images, and interact with user interface elements on a computer screen or monitor.

It works well with analog monitors or CRT monitors because of the way such monitors scan the screen which is one pixel at a time giving the computer a way to keep track of the expected scanning time by the electron beam and assume the pen’s position based on the latest timestamp of the scanning.

The light pen allows the user to point to displayed objects or draw on the screen similar to a touchscreen but with greater positional accuracy. The first light pen was created around 1955 as part of MIT’s “Whirlwind” project. The usage of the light pen was expanded in the early 80s to music workstations like Fairlight CMI.
