Procuring classroom technology is a critical investment. This guide breaks down the core differences between installing traditional projectors and modern digital smart boards.
Brightness and Visibility
Projectors struggle in brightly lit Indian classrooms, requiring curtains to be closed. Digital panels emit direct LED backlighting (up to 450 nits), maintaining crisp visibility even under midday sunlight.
Writing Precision
Interactive Flat Panels offer infrared touch writing with less than 5ms latency, matching the feel of pen on paper. Projectors have visible lag and require regular calibration.
Total Cost of Ownership (TCO)
While a basic projector has a lower initial cost, the recurring bulb replacement, high power consumption, and wiring costs make Interactive Panels more economical over a 5-year span.
