New Liquid Crystal Technology May Bring Us Mind-Blowing Vivid Screens!

Unbelievably realistic screen displays may soon reach stores! With this new technology, future monitors may surpass the most vivid resolutions available today. An international group of researchers published the findings in the journal Optical Materials Express. They said that for the new technology, the new liquid crystal is optimized for field-sequential color liquid crystal displays (LCDs). It resulted in displays that pack more pixels into the same space while also reducing the power needed to run the device.

“Today’s Apple Retina displays have a resolution density of about 500 pixels per inch,” Shin-Tson Wu, who led the research team at the University of Central Florida’s College of Optics and Photonics (CREOL) told OSA. “With our new technology, a resolution density of 1500 pixels per inch could be achieved on the same sized screen. This is especially attractive for virtual reality headsets or augmented reality technology, which must achieve high resolution in a small screen to look sharp when placed close to our eyes.” The first blue-phase LCD prototype was actually demonstrated by Samsung in 2008. However, by that time problems occurred due to high operating voltage and a slow capacitor charging time. These complications are resolved through the merging of Wu’s research team and liquid crystal manufacturer JNC Petrochemical Corporation in Japan, as well as display manufacturer AU Optronics Corporation in Taiwan. This group of experts combined the new liquid crystal with a special performance-enhancing electrode structure. The result is a technology that can achieve light transmittance of 74 percent with an operation voltage of 15 volts per pixel. This means field-sequential color displays may be used for product development. “Field-sequential color displays can be used to achieve the smaller pixels needed to increase resolution density,” said Yuge Huang, first author of the paper. “This is important because the resolution density of today’s technology is almost at its limit.”
