Liquid-crystal display (LCD) has become the world’s leading display technology. It’s used to power everything from TVs and computer monitors to smartphones, tablets and even human machine interfaces (HMIs). But not all LCD technologies are the same. Some are newer and more advanced than others. One of the latest LCD technologies to hit the market, for example, is blue phase LCD, which we’re going to discuss in this blog post.
Overview of Blue Phase LCD
Blue phase LCD is a new type of LCD technology that’s characterized by the use of twisted cholesteric phases in a blue phase. In other words, it doesn’t use liquid crystals in a nematic phase — the type of phase that’s currently used with other LCD technologies like in-plane switching (IPS) and twisted nematic. With blue phase LCD, the liquid crystals are suspended in a blue phase, resulting in some unique benefits.
To better understand blue phase LCD technology, you must first understand how the blue phase works. Basically, liquid crystals enter the blue phase between the phase in which they become twisted, known as the nematic phase, and the istotropic phase.
Benefits of Blue Phase LCD
How does blue phase LCD compare to other types of LCD technologies? For starters, it’s able to achieve significantly faster frame reports. According to Wikipedia, some of the world’s first blue phase LCDs were introduced in 2007, boasting frame rates of approximately 100 to 120 Hz. Furthermore, blue phase LCDs are incredibly responsive — even more so than other leading LCD technologies. It’s not uncommon for blue phase LCDs to have a 10 to 100 microsecond response time.
As explained in this article, blue phase LCDs can switch the lighting of the liquid crystals roughly 10 times faster than other types of LCDs. As a result, they don’t have to project light through a color filter.
The Bottom Line on Blue Phase LCD
Blue phase LCD is a new and advanced type of LCD technology that involves the use of a unique phase, known as a blue phase, in which the liquid crystals are suspended. It allows for faster frame reports and a higher level of responsiveness when compared to existing LCD technologies. The only downside is that it’s still a new LCD technology, so not many manufacturers offer it. And the manufacturers that do create and sell blue phase LCDs offer them at a high price. Hopefully, this gives you a better understanding of blue phase LCD technology and how it works.
