IPS versus VA Overview
If you did not know, LCD stands for liquid-crystal display. When looking into buying one of these TVs whether cheap or expensive you’re going to be looking at two variations of LCD displays. Those two types are In-Plane Switching or IPS and Vertical Alignment or VA. They both come packed with pros and cons so it can be hard to decide on what you should go with.
I’m going to explain a bit about these to better help you with what the best for you.

Talking about IPS panels is a little bit like talking about a legend from a long time ago. This is because IPS panels came about to help solve a huge issue that many LCD TVs were struggling with during the 1980s. The biggest issues that were combatted were the poor viewing angle and how the TVs were not able to reproduce colors that our eyes see naturally. This was done through literally rearranging molecules of the liquid-crystal between the plates inside the TV.
Some of the techniques created over the years include Horizontal IPS or H-IPS, Enhanced IPS or E-IPS, and Professional IPS or P-IPS. All of these techniques were developed by LG have their own benefits. Such as a better contrast ratio, a better aperture for light transmission, a deeper color gamut and better viewing angles.
- Accurate color from all viewing angles.
- Little to no “ghosting” or trails from motion heavy scenes.
- Clear and consistent images or scenes.
On the other hand, compared to IPS panels, speaking about VA panels is little like speaking about an up and comer in a wrestling world. They offer tons of options and real great features, but some of their shortcomings may have you rethinking if you prefer them. This is because VA panels do not share the same viewing angle which many people will not prefer.
VA panels achieve their desired effect through ensuring the liquid-crystals are vertically-aligned to the glass panes inside the TVs. The voltage applied and not applied is the biggest factor in how it works. When voltage is applied the crystals begin to tilt. This allows for light to pass through and thus allowing for the shutter-filter combo to do their magic. When no voltage is applied the liquid-crystals are perpendicular or placed at a right angle adjacent to the glass panes inside the TV. This prevents light from passing through and produces a almost black color reproduction. There are minor leaks of light, but it is minimal.
There are couple techniques of VA that work well and offer their own benefits, but for the most part the benefits remain the same. These techniques are Multi-domain Vertical Alignment (MVA), and Patterned Vertical Alignment (PVA).
- Better than average viewing angle (poorer than IPS panels though)
- Great contrast ratios
- Strong response time for motion heavy content
- Good color reproduction
- Terrific colors gamuts
Depending on the type on panel a TV, it can have a large effect on the overall picture value a TV can have. There are some clear advantages to one over the other, but be careful as the price of the TV will often mirror more expensive equipment. I hopw this helps and have a good day!
