Lighter, More Energy Efficient Video Wall Platform Features the Industry's Only Factory Calibration Process that Delivers Out-of-the-Box Pixel to Pixel Color Uniformity MAHWAH, N.J., – Sharp Imaging and Information Company of America (SIICA), a division of Sharp Electronics Corporation (SEC), expands its PN-V video wall series with the launch of its second 55" Class (54.6" diagonal) PN-V550 LED Ultra-Slim Bezel professional monitor. With a bezel-to-bezel width of just 3.5mm and up to 500 cd/m2 brightness, the PN-V550 display is nearly 40 percent lighter and 40 percent more energy efficient than the Sharp 60" Class PN-V600A Professional Video Wall Display, and features Sharp's Uniform Color Calibration Technology (UCCT).
UCCT is the industry's only factory calibration process that delivers out-of-the box pixel to pixel color uniformity between multiple video wall monitors--encompassing chromatic intensity, luminance, and hue.
How Sharp's UCCT Ensures Uniformity of Color and Brightness
1. A 3D "pixel to pixel" MURA correction is performed on the factory production line using SHARP UCCT software (Uniform Color Calibration Technology). Using the very accurate L*ab methodology, all chromatic, luminance and hue values are calculated to remove any MURA impurity from the entire display screen area achieving a consistent uniformity of white and all colors, across each display from screen edge to center and between all displays across the entire video wall.
2. This advanced MURA correction process is eventually saved onto a unique combination of separate Look Up Tables (LUT) on board every PN-V550 display, (i.e. known as "hardware calibration"), permanently saving and applying all correction data to obtain a consistent and uniform color rendering across each display from screen edge to center, and between all displays across the entire video wall, regardless of any input signal the display is fed from.
3. In addition to UCCT MURA correction, Sharp's factory calibration process adjusts the white point and colors to a pre-defined common temperature target across each display from screen edge to center, and between all displays across the entire video wall.
