What are the three types of LCD displays?

Views: 264 Update date: Mar 24,2023
Liquid Crystal Displays (LCDs) have become ubiquitous in our daily lives, from our smartphones to our televisions. LCD displays have replaced older technologies like Cathode Ray Tube (CRT) displays due to their thinner form factor, lower power consumption, and better image quality. LCD displays come in three different types, namely Twisted Nematic (TN), In-Plane Switching (IPS), and Vertical Alignment (VA). 

Twisted Nematic (TN) displays:

TN displays were the first type of LCD displays to be mass-produced. They are the most common type of LCD displays found in devices like calculators, watches, and even computer monitors. TN displays are cost-effective and offer high refresh rates, which make them suitable for gaming and other fast-paced applications. However, TN displays have narrow viewing angles, limited color reproduction, and poor contrast ratios. This makes them unsuitable for professional applications like graphic design or photo editing.



In-Plane Switching (IPS) displays:
IPS displays were introduced as an improvement over TN displays. They offer wider viewing angles, better color reproduction, and higher contrast ratios. IPS displays are suitable for professional applications like graphic design, photo editing, and video editing. However, IPS displays have higher power consumption and slower response times compared to TN displays. This makes them unsuitable for gaming and other fast-paced applications.

Vertical Alignment (VA) displays:
VA displays are a compromise between TN and IPS displays. They offer better contrast ratios than IPS displays and wider viewing angles than TN displays. VA displays are suitable for applications like movie playback, gaming, and professional applications like graphic design and photo editing. However, VA displays have slower response times compared to TN displays, which can result in motion blur.
