5 Factors to Consider When Choosing TN vs IPS for Interactive Whiteboards

Understanding the Basics of TN vs IPS

TN (Twisted Nematic) and IPS (In-Plane Switching) are two commonly used LCD panel types in interactive displays. LCD panels work by controlling light through a layer of liquid crystals, but the arrangement of these molecules differs between TN and IPS.

TN Panels: Liquid crystals are twisted to control light passage. This design allows very fast response times, making it suitable for fast-moving images, but it has limited viewing angles and narrower color gamut.

IPS Panels: Liquid crystals rotate in-plane, providing ultra-wide viewing angles and accurate color reproduction, ideal for professional, collaborative, and high-visibility applications.

When selecting a panel for an interactive whiteboard, your choice should depend on usage scenarios, viewing requirements, and interaction needs.

Main Differences Between TN vs IPS for Interactive Flat Panels

Feature	TN Panel	IPS Panel	Implication for Interactive Whiteboards
Viewing Angle	~160°	178°	IPS ensures all participants see consistent colors from any angle.
Color Accuracy	Narrow gamut	Wide gamut	IPS delivers vivid, true-to-life colors for presentations and teaching.
Response Speed	1–5ms	4–10ms	TN is slightly faster for very high-speed video, but modern IPS is sufficient for most interactions.
Touch Accuracy	Lower precision	High precision	IPS works better with multi-touch and pen input.
Cost	Lower	Higher	TN can reduce cost in budget-limited projects, but IPS offers better long-term value.

5 Key Factors to Consider When Choosing TN vs IPS

Image Quality

TN panels have deeper blacks but limited color coverage.

IPS panels deliver vivid colors and consistent image quality, essential for classrooms, meeting rooms, and collaborative work.

Viewing Angle

IPS panels maintain color and brightness across 178°, ideal for group participation.

TN panels may cause color shifts when viewed from the side, unsuitable for multi-user environments.

Touch and Interaction Accuracy

Interactive whiteboards require precise touch response and multi-touch capability.

IPS panels integrate seamlessly with touch sensors and stylus input for accurate writing, annotations, and gestures.

Usage Environment

TN panels can handle high-brightness outdoor applications and are slightly more stable under extreme temperatures.

IPS panels are designed for indoor classrooms, offices, and collaborative spaces where viewing comfort and color accuracy are critical.

Cost vs Long-Term Value

TN panels are cheaper but compromise on viewing angles and color accuracy.

IPS panels cost more but enhance user experience, engagement, and long-term satisfaction, particularly for Qtenboard interactive whiteboards used in high-end classrooms and corporate settings.

Which is Better for Interactive Whiteboards?

For most interactive whiteboard applications, IPS panels outperform TN panels. They provide:

• Wide viewing angles for group participation
• High color accuracy for presentations and teaching content
• Reliable touch performance for pen and finger input

TN panels may still be chosen in budget-constrained scenarios or very high-speed image environments (like e-sports or quick-signage playback), but for professional classrooms and offices, IPS is the clear choice.

How to Make the Right Choice for Your Qtenboard Interactive Whiteboard

When selecting a Qtenboard interactive flat panel:

• Identify your usage scenario: classroom, meeting room, corporate showroom, or collaborative workspace.
• Consider number of users and viewing angles required.
• Prioritize touch accuracy and interaction smoothness for annotations and group activities.
• Evaluate your budget vs long-term value—IPS panels provide the best overall experience.
