Quattron Pro Drive Gives Quattron Full-HD LCD Panels Resolution Equivalent to 4K*1

Image detail is determined by resolution, and resolution in turn is greatly affected by the number of luminance peaks*2—the points on a pixel where relative lightness is high. With the Quattron Pro Drive, Sharp has successfully created four luminance peaks in each of the pixels on a full-HD panel employing its proprietary 4-color*3 technology. This gives the full-HD panel highly detailed images equivalent to 4K*1. Resolution is improved through a panel structure that illuminates four parts of each pixel separately. In the horizontal direction, the green and yellow subpixels, where the brightness peaks occur, are rendered separately; and in the vertical direction, subpixels are driven separately in the top and bottom parts. High-definition (full-HD) image signals are given higher brightness and more color information with the 4K upscaling circuit, which reformats the image to make it smoother and more detailed. With the 4K image signal, the image is reformatted based on information from the original image, resulting in highly detailed images on the TV screen.

*1
Evaluation of the resolution of a brightness signal stipulated by Sharp using a 3,840 × 2,160 resolution chart. Not a 4K LCD panel.
*2
The point where it is easiest to perceive brightness level when white is being displayed. The luminance peak occurs at green and yellow, colors where the relative lightness (sensitivity to brightness of light wavelength) is high.
*3
Unlike the conventional 3-color display method, this is a proprietary Sharp method for reproducing colors on a display.
