Document management Communication management Energy management contact UCCT - a great way to create perfect screens Standard large screens often have different shades of white visible on individual component screens. Dark spots or stains can affect the quality and consistency of the content displayed. This haze phenomenon is called "Mura", which means "heterogeneity" in Japanese, and is normally irreversible. Sharp has found the perfect solution ... Technology Uniform Color Calibration Technology (UCCT) developed by Sharp removes any contaminants and visible image non-uniformity caused by the effect of Mura by a gain corresponding RGB pixels in all invalid. The result is an image with consistent dots and colors across the entire screen. How it's working? Step 1: screen + UCCT UCCT is a three-dimensional hardware calibration point by point ("3D pixel by pixel") carried out in the factory using a state-of-the-art "xyz" camera to apply Mura effect correction and color calibration in all LUT tables. After applying the correction, the improvement is visible, but each screen has its own UCCT profile, and the white dots on the individual screens of the large screen may still differ from each other. Therefore, for the best results, another step is needed. Step 2: screen + UCCT + calibration An external sensor measures the white points and color profiles of each screen. The Sharp Display Installation Tool with Calibration (DITwC) software updates (hardware calibration) the screen LUT to fit over the entire screen area. Calibration with an external sensor is applied to each screen and the white dots are matched with the DITwC software to create the perfect large screen. The Mura effect correction usually remains stable over the life of the screen, but may need to be refreshed from time to time with DITwC software as aging effects can lead to new white spots. Unique approach The Sharp UCCT algorithm is a leading market solution because no other manufacturer offers: Mura Correction based on L * ab: Produces a linear representation of all visible colors that is close to how the human eye perceives colors. 3D Color Control: Uses a combination of built-in Look Up Table (LUT) tables. White Dot Calibration: Ensures full adjustment to a predefined color temperature from the edge to the center of the screen and across all component screens using the L * ab algorithm. As a result, all screens are perfectly homogeneous and perfectly matched over the entire surface of the large screen, which creates great possibilities of transmission on a large-size and high-quality screen.
