Although 4K is not yet popular, the new LCD technology has already brought future expectations to a higher level. "Optical Society" published a research report this week entitled "blue phase liquid crystal field sequential color display", the optics and photonics scientists Florida College of the University of Central Shin-Tson Wu is in charge of this team, he said they The technology can achieve a resolution of 1500 pixels per inch with a smaller power consumption on a screen size screen of an iPhone.
Wu mentioned in the statement: "This is especially meaningful for virtual reality head-mounted and augmented reality technology, because the goal of both is to achieve extremely high resolution on a small screen, so that it is placed in the user's entire field of vision. It’s not too bad.â€
The so-called blue phase LCD is different from the nematic liquid crystal commonly used in current LCD displays, which use red, green, and blue sub-pixels as color filters to color the LED backlight. The blue phase LCD does not need these sub-pixels, the LED itself will automatically convert the color at high frequency, and the human eye can only see the mixture of these colors. Just because three sub-pixels are not needed, the same space can hold more pixels, so the resolution will be higher. The blue phase LCD also reduces the voltage required for imaging.
Currently Wu's research team is expected to build a prototype next year and then work hard to apply it to VR heads. The concept of blue-phase LCD technology has been in existence for nearly a decade. In 2008, Samsung released a 15-inch model with a refresh rate of 240 Hz, but it has not been used in mass production.
