In the picture, is an example of a woman using a light pen to highlight text on the screen. Jun 28, 2014 · a light pen is a peripheral input device, used for inputting analog information in a digital format.the analog information may be a plan or drawing which needs to be digitized so that it can be. A light pen detects changes of brightness of close screen pixels once scanned by crt ray and communicates the timing of this event to the pc. Since a crt scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the pen's position from the latest timestamp. When the light pen is brought closer to computer screen or touched on the screen then computer is able to determine where on the screen the pen is aimed at.
The light pen works well with 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 infer the pen's position based on the latest timestamp of the scanning.
It is used as a standard pick device with many graphics system. Since a crt scans the entire screen one pixel at a time, the computer can keep track of the expected time of scanning various locations on screen by the beam and infer the pen's position from the latest timestamp. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. Oct 11, 2017 · 1. As the light pen was moved across the screen, the part of the tracking cross sensed changes thus allowing the direction of movement of the light pen to be ascertained. If background color or intensity, a light pen can be used as a locator. May 18, 2018 · the light pen was used to draw items with the aid of a tracking cross. Functions of light pen important functions of a light pen is given below: The light pen works well with 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 infer the pen's position based on the latest timestamp of the scanning.
