Power to the subpixel: new tech could triple the resolution of LCD screens

Blaze Display Technology Co., Ltd. | Updated: Jun 26, 2017

【R&D Department of Blaze Display】University of Central Florida researchers might triple the resolution that LCD screens can pump out by three-fold, virtually overnight. The breakthrough was made possible by a novel surface which allows individual subpixels to display any of the three primary colors.

TVs and every other type of screen have gone a long way since their humble beginnings. But if there’s one thing consumers will always fawn over it’s got to be a bigger, better, crisper display. The first two usually are just a question of how much money you’re looking to spend, while the latter — well, it’s had a hard cap up to now.

One image to rule them all

Think of screens as a reverse compound eye. They build the complete image by stacking lots of tiny images — pixels — together, and by altering each pixel’s color, you alter the final image. In turn, each pixel is built by stacking three tinier images — subpixels — on top of one another. But subpixels are locked to a single color, either red, green, or blue, the three primary colors in television.

A white backlight shines through the subpixels and they’re either turned on or off by a shutter to create the pixel’s final color. For example, if the pixel has to be blue, the LCD shutter will block out the green and red subpixels. If it has to be purple, it will only cover the green subpixel, and so on. Finally, the intensity of the backlight determines the overall brightness of the screen and how light or dark the final color will be.
