–
Horizontal resolution
Quattron Pro has two high bright color (Y/G).
By controlling and utilizing these color individually by new algorithm, Quattron Pro creates two
gradation in one pixel in horizontal direction. Thanks to this feature, Quattron Pro achieves
higher resolution also in horizontal direction compared to FHD panel.
higher resolution also in horizontal direction compared to FHD panel.
Man’s “color cognitive ability” is low compared to “luminosity cognitive ability”.
Retina is composed of two kinds of photoreceptor cells:
Rod Cell (Cognition of light and darkness) and Cone
Cell(Cognition of color)
Because most of photoreceptor is Rod Cell,
man’s eye is more sensitive to luminosity.
Therefore Quattron
Pro’s Horizontal luminosity resolution is as the same level as 4K by
utilizing Y/G subpixel, and gives us the completely higher resolution impression compared
to conventional FHD panel

Subpixel structure
•
The secret lies on the width of each sub
pixel:
pixel:
•
Blue & Red > Wide
•
Green & Yellow > Narrow
•
This means that Green & Yellow are
independent, and Blue and Red are
shared with sequential pixels.
