RADIANT:LED display correction demand will increase year by year

Radiant Imaging is a leading global CCD imaging system of color and brightness measurement technology and product suppliers, the latest release of the Vision system can make the LED display in the entire life cycle to get the best visual quality optimization. The day before the news photo attended by Radiant Imaging Chinese agents Sha Yibo design system (Shanghai) Co., trade organization press conference, and the face-to-face exchanges with Radiant Imaging CEO Ronald Rykowski sir, let us for the new LED display correction technology has a more in-depth understanding.

Compared to other LED screen display products, has the advantages of clear image, bright color, good stability, high brightness, high luminous efficiency, long life, low power consumption, the LED display is not restricted by space, can be designed according to user requirements of the screen size, display text, pattern, image. At present, LED is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, and full color. Today, whether the world's LED big screen industry or China's LED big screen industry are at a stage of rapid growth. Especially in recent years, under the trend of energy saving and consumption reduction, LED technology has been widely used, and the market capacity will be increased by 15% annually.

According to DIGITIMES, the domestic large LED display output from 2008 to 2010 were $1 billion 180 million, $1 billion 640 million, $2 billion 320 million, annual growth rates were 34.1%, 39%, 41.5%, is the LED applications (including mobile phone backlight, automobile lamp, lighting, electronic equipment, etc.), the annual growth rate of the most significant products.

LED display screen correction technology to ensure the quality of the key

Since, due to the manufacturing process and other reasons, there are different characteristics of LED, when the display module is integrated LED display these made of LED, if none of these differences are enough compensation, so will lead to different LED display brightness and color visible; at the same time LED display in the installation of a period of time, LED will change with the attenuation of luminance and chrominance time, but each LED attenuation level is different, this will cause the LED to display the visual quality is greatly reduced; in addition, the LED of the LED display module is damaged in the process of using the replacement lead to a new module and the whole screen does not match, will greatly reduce the LED display visual quality.

At present, the production of LED display is more, its technology is relatively mature. The structure and principle of the display screen made by different enterprises are similar. How to improve the technical performance and reduce the cost of the display is the key to the competition. Now, the LED display on the market price is basically the same, but the quality of the screen production of different, its reason is in many aspects, such as LED display differences in quality, brightness, brightness uniformity, module encapsulation technology, communication mode, data transmission between the anti-interference ability and the difference of the control circuit, and the LED display panel correction technology can effectively help enterprises solve these problems. We found in the application, after LED correction of the display is not only a good uniformity, but also shows the image brightness, color effect is better, longer life. Radiant Imaging CEO Mr. Rykowski Ronald said. Radiant Imaging is a leading global CCD imaging system of color and brightness measurement technology and product suppliers, the latest release of the Vision system can make the LED display in the entire life cycle to get the best visual quality optimization.

Rykowski pointed out that the currently used LED display correction technology enterprises are still relatively small, but as the industry demand for high-quality display more and more, LED display correction technology will get a promotion, and eventually become one of the key technologies to ensure the quality of the.

Innovative technology to help manufacturers LED display

Rykowsk said, in order to meet the needs of enterprises of the LED display module, calibration requirements of existing LED screen, and replace modules and other modules (the remaining screen) uniformity, Radiant Imaging company launched Vision system for LED display the entire life cycle to provide special solutions to improve the visual quality of the system, including the VisionCAL LED display, LED display correction correction system of VisionLINK video processor and VisionMATCH LED display module replacement correction system.

VisionCAL is Radiant Imaging's LED display calibration system, before the name of PM-LED C. VisionCAL combined with RadiantImaging's ProMetric imaging brightness / colorimeter for LED display pixel level measurement, using VisionCAL software to generate correction factor. The correction coefficient adjusts each independent LED in the LED display screen through the control system of the LED display screen, so as to achieve the expected brightness and chroma consistency.

As for VisionLINK is the latest product of Radiant Imaging, LED display online correction video processor. At present, not all of the LED display support, the correction factor, especially those early LED display. VisionLINK solves this problem by applying the VisionCAL generated correction coefficients directly to the DVI video signal, which is then sent to the LED display to achieve the correction effect.
