A digitizer is the component in a two-in-one laptop that enables finger-based or stylus input on the screen. It is responsible for converting touch inputs into digital signals that the device can interpret.
Why Digitizer?
A digitizer is integrated into the screen assembly and works to detect and process inputs such as taps, swipes, or pinches.
This is a standard feature in modern touchscreens, enabling functionality for both finger-based and stylus-based interactions.
Incorrect Options:
A. Fingerprint Scanner: Used for biometric authentication, not for touch input on screens.
C. Stylus: An accessory that interacts with the digitizer but does not provide the input functionality itself.
D. Inverter: Used in older displays to power backlights, especially in LCD screens with CCFL technology, and has no role in touch input.
