Light sensitive elements
A light pen is an optical device that detects light emitted by a computer screen to determine the position of the pen on the screen. It is used as an input device to interact with computers by pointing, clicking, and drawing on the screen.
A light pen works by detecting light emitted by a computer monitor or screen when the pen's tip touches the surface. The pen has a light-sensitive photodiode at the tip, which detects the light and sends a signal back to the computer to identify the pen's position on the screen. This allows users to interact with software by pointing and selecting on the screen.
A light pen operates by detecting the light emitted from a computer screen when activated by a user pressing the pen against the screen. The screen emits electron beams that are picked up by the light pen, allowing the computer to determine the location on the screen that the pen is pointing at.
One disadvantage of a light pen is that it requires a display with a special coating to detect the light emitted by the pen accurately. Additionally, it can be less precise than other input devices like a mouse or stylus.
A light pen is called so because it is a handheld input device that can detect light on a computer screen. It uses a photocell to detect the presence of light emitted by the screen, allowing it to function as a pointing device.
