Digitizer

A digitizer is a device that allows users to input drawings, sketches, and handwritten notes into a computer. It's also a graphics tablet, drawing tablet, or pen tablet.

A digitizer has a pressure-sensitive flat surface and a stylus or pen-like instrument that users draw or write with. The digitizer's sensors detect the stylus's movements and pressure levels and send the data to the computer. The computer then processes the data and translates it into visual elements on the screen.

Digitizers are used for many purposes, including:

• Drawing and painting: Digitizers can recreate the drawing experience with a pen on paper.
• Creating and editing notes: Digitizers can create and edit handwritten notes or text documents.
• Digital signatures: Digitizers are a base component of many digital signature technologies.

On a laptop, a touchscreen digitizer is an additional screen that sits on top of the laptop's LCD screen. There are two types of touchscreen laptops:

• Standard LCD with separate digitizer glass: The LCD displays the image, and the digitizer glass responds to touch.
• Embedded touchscreen: The touch is embedded into the LCD during manufacturing.
