LED display technology difficulties

LED display shows the true colors
Color depth video processing and decided to show the video image quality. Daktronics Inc. LED color depth 4,400,000,000,000. If the screen wearing a black jacket, the color depth 4,400,000,000,000 so you can distinguish between different black and the details of the different regions, such as the black clothes of wrinkles and folds, and so on. In addition, Daktronics to use its data processing to achieve accurate digital video input (such as NTSC, PAL, HD) needed to adjust the color and gamma.

High-resolution LED display
Optimization of full-color LED video technology has many aspects. LED video display requirements of a wide color depth, to be effective gamma correction and color values in order to make the best use of LED display. Video processing engine and zoom through the filter to make full use of lighting LED. When the input image information for more than a few pixels when it is necessary to carry out zoom. Daktronics of scaling can be dealt with the right to use images, can zoom resolution LED display for more than narrow the information to the screen the most appropriate level, while maintaining a clear image of the show. Daktronics lighting of the filter algorithm station also showed a clear and precise help there.
According to the display used by different types of LED, image processing is also different. For example, the 3-in-1 LED, its ability to deal with the sub to a package of 3 LED pixels. The light-LED, LED's physical location * need to work closely and very well integrated, so as to effectively carry out the zoom and LED pixel brightness changes. Some companies deal with the brightness of the LED is the dynamic, virtual or enhance the resolution dealt with the handling of Daktronics refers to the location of the means of pixels (Positional Pixeling) technology.
Barco LED modules of the double-pixel technology, from physics to make visual resolution doubling to provide greater clarity and enhanced visual resolution. The use of two-pixel technology, can accurately addressing each LED unit, resulting in smoother images and higher resolution display.
Daktronics design and manufacture their own modules and video processor. Can strictly control the input, processing and zoom after the module for the show. We can optimize the gray scale and color controller, to obtain the best image display
Daktronics own module production, rather than using other people's production and assembly of modular LED screen. From beginning to end have strict quality control.
In addition, Daktronics has also developed a proprietary method of correction to ensure that our display throughout the life of the show consistent results.

LED displays using high-pixel display
Daktronics to adopt the technology PurePixel the true image pixel display. PurePixel technology to ensure that each LED pixels in at least one red, green and blue units. In addition, Daktronics system with sub-pixel processing power to achieve pixel-level processing, or LED. This pixel-level processing or LED can be applied in accordance with customer needs and preferences in the video processor to start on or off.
In the pixel level, or LED control to deal with a number of advantages. For pixel-level control of vivid colors transform the contents of the application of special, it can maintain the integrity of the LED colors to avoid color drift. Pixel edge asked to deal with the clarity and consistency of color applications, such as the text shows that the ideal in particular. LED treatment can make subtle changes in the content of the image sharper. For example, the close-up images of grass, many details of the color. LED treatment can be made of grass and leaves twill curved become more smooth, step less effect.
* LED display can be a stable and
To keep the system can *, and preventive maintenance of the site is very important. In addition, strong water-proof and dust-free analog design, can withstand harsh outdoor environment. For fixed installation, the modules can be placed in accordance with the specific requirements of custom installation of a solid structure, constitute a whole.
In parts procurement, manufacturing and product design in the process of application of the "overall quality" people management technology for producing high-quality products and to protect the user's long-term investment to provide a guarantee. Embedded PC so that the modules have to deal with intelligence and scalability, built-in thermal modular systems management products with higher quality and longer life
Modular design, circuit design features to connect into different modules, each of the modules only minimal contact can be greatly enhanced system stability, and * can be. Show some of the distributed scanning technology, part of the show is divided into different units, the independent scan of each unit between the synchronous control signal, indicating increased stability.
Indoor and outdoor LED screen brightness and different levels of protection
Outdoor LED display brightness of the display than the indoor, outdoor LED display for the 5000-6000 nits typical brightness, indoor LED screen in 2000 while Bennett. Outdoor-to high brightness in a variety of environmental conditions, even under direct sunlight can be seen, Room Service is also heat-LED display, water-resistant, anti-snow, and so on. Outdoors, LED display with a cold, waterproof, dustproof and cooling functions.

LED display system
LED display system in general by the source, the central control, and the show Edit control of parts.
Source, including video, DVD and PC signals, and so on. Video playback and video signals to receive local broadcast signals; DVD players play DVD, VCD, and other video material; PC used to enter text, the title may also be connected to the Internet, play digital animation and images.
Central controller to a different digital signal source, through the production of software, to send Finally, LED system.
Editor easy to control the production staff revealed that the content of the non-production requirements, conform to the development of network technology, the introduction of application-oriented, network-oriented concept, the pursuit of open, networked and personalized. LED display, if more than a certain distance away from the need to use fiber-optic transmission system in order to speed up the transfer speed and improve the quality of transmission.
