Functional Category: Output Device
Computer Peripherals: Like a monitor, a projector receives video signals and displays them.
Audio-Visual (AV) Equipment: Used for presentations, meetings, and home theaters to display visual content.
2. Technology Categories (Imaging Engine)
DLP (Digital Light Processing): Uses tiny mirrors for high contrast and smooth, fast-motion video.
LCD (Liquid Crystal Display): Channels light through liquid crystal panels, often chosen for high color accuracy and brightness.
LCoS (Liquid Crystal on Silicon): A hybrid of DLP and LCD, typically found in high-end home theaters for superior image quality.
Laser/LED: Refers to the light source used, providing longer life, better energy efficiency, and lower maintenance compared to traditional lamp-based projectors.
