Tech Developed to Maintain LCD Screens without Data Signals

A Korean research team has successfully developed a tech to make a memory-type liquid crystal display (LCD) that can maintain a screen without sending data signals.

On July 23, Professor Kim Jae-hoon from Hanyang University and Professor Kwak Jin-seok from Yeungnam University announced that their research team succeeded in developing a memory-type LCD that can keep its screen going, even when data signals discontinue, using the phenomenon that the surface of liquid crystals slides easily. The research team said that it will be possible to first use the research findings in slowly-moving LCDs like those used in e-books, LED billboards, and e-signs for prices or menus. In that case, they said that the newly-developed tech could reduce power consumption by nearly 100 percent.  

Professor Kwak noted, “I think that our study will be able to be used in the development of memory-type optical elements that can be utilized in optical communications, dynamic focal spot changing lens, cameras, scanners, printers, polarization sensors, and polarization elements, in addition to slowly-moving LCDs.”

The research findings were first published online on June 23 by Scientific Reports, a scientific journal published by the Nature Publishing Group.
