WVA displays are highly popular for their eye-catching color and wide viewing angles. In fact, Lenovo now offers more laptops, tablets and monitors based on In Plane Switching or WVA display technology than with the earlier TN (Twisted Nematic) construction – although TN models are still prized by some users, such as hyper-competitive PC gamers.
So, what does an WVA display really deliver? Which laptop and monitor buyers are most likely to benefit from WVA technology? And why do some users still prefer older-style TN displays? Read on for answers to these and other questions.
WVA and TN are different kinds of TFT LCDs (Thin Film Transistor Liquid Crystal Displays). At the simplest level, LCDs rely on the light modulating properties of energized liquid crystals – along with coordinated light filtering polarizers (both behind and in front of the crystals) -- to control what appears on the screen. By applying voltage to each crystal (or not), light is made to pass through the polarizers (or not). When these changes are managed at microsecond intervals, you get smooth moving images.
LENOVO OFFERS DOZENS OF LAPTOPS WITH WVA DISPLAYS:
TN and WVA displays differ in how their light-influencing polarizer layers are aligned. If this sounds too technical, just know that when polarizers are aligned similarly, light can pass through, but when they’re put in different orientations, light is blocked. And when you place liquid crystal molecules between the polarizer layers and apply voltage, interesting things happen:
There’s a lot more to it, of course. But this gives you the general idea of how TN and WVA displays differ. And it’s these differences that give each type of display distinct advantages for specific customers. For example, the parallel polarizer alignment on WVA displays is one reason they can be viewed from extreme angles compared to their TN counterparts. Meanwhile, the way TN displays let light through by default (without applying voltage to disrupt the flow) is one reason TN displays have faster response times and refresh rates than similar WVA models.
Your need for WVA technology depends on how you will use your laptop display or standalone monitor. Here’s a quick run-down of the relative advantages of WVA and TN displays. How does each type match your requirements?

WVA displays and monitors are known for having several advantages:
One perceived disadvantage of WVA monitors compared to TN ones is their relatively slower refresh rates (the time needed to reconfigure each on-screen image) and response times (the delay when a pixel changes from an active to inactive state). But these delays are measured in milliseconds, so the vast majority of users – say, everyone but advanced PC game players -- will not be impacted. WVA is plenty fast enough for streaming movies, making video calls, and so on.
VERSATILE LENOVO TABLETS HAVE WVA DISPLAYS, TOO:
Despite the growing market prevalence of WVA displays, there’s still a dedicated user base for TN technology. Here’s why:
