For production of wide-color-gamut 8K
For wide-color-gamut production, we have developed an LCD that uses laser diodes (red, green, and blue) for the backlight source. The gamut coverage ratio is 98% (in the xy chromaticity diagram).
To convert wide-gamut content into HDTV content, we have developed a high-quality gamut mapping device that minimizes perceptual hue changes. This device does not cause significant texture loss and discontinuous tones, which are generated with simpler gamut mapping algorithms commonly used.
We are working towards practical application of 8K wide-gamut direct-view displays and color gamut mapping devices in time for the start of 8K broadcasting.
●Wide-gamut system colorimetry: Ultra-high definition TV employs wide-gamut system colorimetry (a system to quantify colors) that can accurately reproduce saturated colors out of the HDTV gamut. (The colorimetry was standardized at ARIB, SMPTE, and ITU-R.)
