| Smartview SV-1 series LED display multi-pixels brightness high-speed measuring system can measure the lumination of all LED light points fast and precisely , provide the brightness data and correction data to the control system of LED screen for that to achieve perfect display effect. The uniformity of LED pixels lumination is a key factor when evaluating the display quality of LED screen. In recent years, many manufacturors and the control system supplier have developed pixel-level correction function. But, the difficulty of acquiring rapidly millions of LED brightness data, which is the base of pixel-level correction, still was a big block standing on the way of the large scale putting into practising. 2009, Shenzhen CAS.VU Technologies Co.,Ltd developed independantly, and launched SV-1 system. It applied CCD imaging measuring theory, by intergrating several tech-fields as:optics measuring, image analyzing and pattern recognition etc, solved perfectly the problem of high-speed acquiring brightness data of LED pixels. SV-1 system measure precisely and high-efficiently. It is suitable not only for using in the factory, but also for the on-site correction. Screen corrected by SV-1, appear an uniform luminance and a pure color, display effect improved greatly. Cooperate with the other one VU product: CCM software，we could adjust the color coordinate to specified coordinate, which would be useful for different batchs of LED fit together in one screen. |
