SoureImaging new technology effectively solves the problem of LED large screen full screen correction

<p> The problem of light decay is almost a problem that every LED instrument has to face. After the LED display is used for a period of time, the color of the image will become blurred, mainly due to the inconsistent light decay of the three LED tubes. When the LCD backlight is used for a while, there is a problem of uneven brightness. LED luminaires change in brightness, chromaticity and illuminance over time. How to find and solve these problems? A few days ago, Shayibo held a press conference and introduced a series of optical calibration instruments that can effectively solve the above problems. They are RadiantImaging's near-field measurement system SoureImagingGoniometer, brightness, illumination, color measurement system ProMetric, high-speed light intensity distribution measurement system ImagingSphere, and Vision series for display calibration.

    According to RadiantImaging CEO Ronald Rykowski, the VisionCAL calibration system belonging to the Vision series can individually adjust each LED in the screen to achieve the desired screen brightness and color uniformity, target gamut and white balance point. The VisionLINK video processor is capable of correcting some of the early "uncorrectable" LED displays.

    ProMetric's CCD is capable of capturing approximately 1.5 million points of data at a time, detecting small defects and making it widely used in R&D and production inspections. The CCD used uses semiconductor refrigeration technology to achieve stable accuracy.

    Liad is a well-known LED display manufacturer in China. The company has undertaken the installation of large-scale LED displays for Olympic scrolls and National Day celebrations. Lu Changjun, the company's technical director, said that the company has been using RadiantImaging's instruments to calibrate the display screens it has produced and produced, and has achieved good results. It has formed a good relationship with RadiantImaging.

    According to Wang Bohua, general manager of Sha Yibo, these displays can be calibrated from a distance, and can be corrected at a high angle of elevation. The white, red, green and blue lights are corrected uniformly during calibration.

    RadiantImaging's optical calibration products are currently represented by Sha Yibo Design Systems Trading (Shanghai) Co., Ltd. and provide a variety of services, including quality consulting, LED display calibration, and LED display quality maintenance.
