At CES 2014, Sharp showed off a curious technology concept that will actually make it to their consumer TVs in 2014. The new Quattron+ technology can reproduce a resolution between Full HD and 4K, says Sharp.

Quattron+ technology – or Quattron Pro in Europe – will be implemented in Sharp’s 2014 TVs. The idea is the bridge the gap between Full HD and 4K resolution in the phase of transition that we are currently undergoing.

Sharp claims that its TVs can deliver 2.5 times the resolution of Full HD by utilizing a special sub-pixel structure; the smaller elements that a full pixel is built from. Typically, three sub-pixels are used to create a full pixels; red, green, and blue (RGB). In recent years, Sharp has added a yellow and fourth sub-pixel. The new Quattron+ concept takes it even further, expanding the sub-pixel structure. In practice this means that Sharp’s new TVs will have 16 million sub-pixels, compared to 6 million for a normal Full HD display, according to Sharp.

Sharp claims that the new display type offers advantages in picture quality when reproducing Full HD content from for example a Blu-ray source that can be upscaled. Sharp’s Quattron+ TVs are also capable of receiving true 4K inputs, but just cannot reproduce the entire 4K resolution. It will be scaled down to something between Full HD and 4K.

Sharp will also release conventional Full HD models and true 4K TVs in 2014. The idea is to make Quattron+ TVs serve as a middle ground, also in price, as true 4K TVs are still relatively expensive. A 70-inch Quattron+ TV is expected to retail for around $3,200.
