Sharp puts colour uniformity at the heart of latest videowall panel
Sharp has released the 139.7cm PN-V551 screen for videowall usage, its first display featuring the company's proprietary uniform colour calibration technology (UCCT).
The two-stage calibration and Mura correction process occurs at Sharp's manufacturing plant and uses L*ab colour space to calculate the chromatic, hue and luminance corrections that are required to guarantee a constant white point temperature. This is followed by a separate calibration process, which ensures a common colour temperature.
As white point temperature tends to change over time due to thermal stress, Sharp has included its DITwC software, so that users can recalibrate this on site, thereby assuring consistent colour replication through the lifetime of the device.
"A videowall display needs to have seamless, even colour and brightness," explains Michael Bailly, product planning and marketing director for visual solutions at Sharp Europe. "Our two-stage Mura correction and colour calibration process is the most advanced technology yet to help installers achieve this, with perfectly matched monitors straight out of the box.
"At Sharp, we are committed to investing in innovative products and we believe the PN-V551 offers a high impact, high quality display solution."
