Light Pen Vs Touch Screen

What's the difference between a pen and a touch screen? 3

A pen is a lightweight, stick-shaped computer input device used in conjunction with a CRT monitor on a computer. It lets the user move the mouse around the screen to view or draw objects, like a touch screen, but with a larger positioning battery. The pen can work with any CRT monitor, but not with LCD screens, projectors, or other display devices.

A touch screen, touch screen, or touch screen panel is a screen overlay capable of viewing and receiving information on a single screen. The overlay effect allows the screen to be used as an input device, eliminating the keyboard and / or mouse as the main input device for interacting with the content of the screen. This monitor can be connected to a computer or a network as an end device. Recent changes in the PDA and CellPne industries have also included touch screens, making these devices more usable.

Light from a flashing pen is detected by a sensor on the edge of the screen, while the input from the touch screen is automatically recognized by the screen, for example when it is turned on.
