Correct Answer:
A. IPS
The correct answer is IPS. IPS (In‑Plane Switching) is a type of LED‑backlit LCD panel technology widely used in premium computer monitors, smartphones, and televisions because of its superior color reproduction and wide viewing angles.
Why IPS Panels Are Preferred in Advanced Monitors
- Exceptional Color Accuracy: IPS panels produce consistent, vivid colors from any viewing angle—typically up to 178 degrees—without the color shifting or contrast loss seen in cheaper TN (Twisted Nematic) panels. This makes them ideal for graphic design, photography, and video editing.
- Wide Viewing Angles: Unlike older LCD technologies, the liquid crystals in an IPS display rotate horizontally, preserving image quality when viewed from the side. This is crucial for collaborative work or large monitors.
- Comparison with Other Technologies:
- CRT (Cathode Ray Tube): The bulky, old‑fashioned monitor technology, now obsolete.
- LCD (Liquid Crystal Display): A broad category that includes IPS, TN, and VA panels. IPS is the premium sub‑type.
- Plasma: A flat‑panel technology used mainly in large TVs in the 2000s, discontinued due to high power consumption and burn‑in.
- Modern Iterations: Advanced versions like Nano IPS and IPS Black have pushed contrast ratios and response times, making IPS the dominant choice for high‑end monitors in 2025.
Therefore, advanced monitors typically use IPS panels.
