Konka is one of the enterprises which involved in the big screen in China. As early as in the 1990s, Konka had provided large display screen to the CCTV studio and some provincial satellite stations. Therefore, Konka Video & Communication has outstanding advantages in large screen image processing technologies, including video processing, image split, video transmission, etc. At present, Konka has acquired many patented technologies in LED control system, and leveled up in the leading place of industry.

Heat Dissipation System Technology
The heat generated by the working LED display Screen is pretty high, in order to ensure that the entire display screen system is stable and reliable, our company designs concerning two aspects.
·On one side, adopt high-efficiency LED light tube to improve power efficiency. Under the same brightness index 30% lower than the common factories and reducing the screen heat effectively.
·On the other hand, in-depth study on heat dissipation system of display screens. Give full play to the characteristics of free convection, meet the IP65 protection of cabinet and work out sealed thermal convection heat removal system, make the system more stable and reliable. 

Distribution System Technology
·When system power on, it will have an instant impact on the current impact of the larger surrounding grid. We use the PLC remote control technology, through the software to delay supply power and partition-powered technology, to ensure the power stable and reliable power supply system. System design has the over current, short circuit, power down and other protection function, and can automatically handle various emergency situations.

Video Processing Technology
·DCDi ™ video processing technology: The pixel distortion generated in the HD signal and non-HD signals transformation will be solved by adjusting the direction of each pixel and ensures the screen more smooth and natural.
·CCS suppression technique to eliminate the chrominance information of the brightness signal, inhibit of the screen flicker and maintain the best chrominance.
·TrueLife™ DigitaTechnology: Enhance the processing ability of image details and inhibit the noise from channel of system.
·3D motion Adaptive Noise Reduction Technology: Adopt the inter prediction technology to ensure smoother motion picture.

Control System Technology (Konka system)
·Unique system structure design, stability control large screen, no whole blank screen, no image flick and no frame lost; (Beijing Pangu 3400 square meters large screen series control experience)
·Realize the accurate brightness and color correction of full-screen. To make sure the screen color uniformity and brightness consistent by the correction of brightness and chroma.
·Control system adopts 16-bit gray scale display technique, the gray scale up to 65,536, so that the display shows extremely delicate gray scale.
·To timely monitor the failure status of each process (including monitor, distributor, and cabinet control board) to make sure system working properly.
·Humanized Operation System: Support thumbnail display, convenient operation, support multi-modes play, easy to select and support instantly insert subtitle.

Unique Energy-Saving Technology
·Use high voltage support to reduce power consumption
·High efficiency power supply design, with PFC and synchronous rectification design to reduce power consumption.
·Adopt self-dependent research and development system, the weak of system only 50 of common system.

Structure Design Technology
·Centralized array of pixel technique, with good luminance properties and enhance pixel effect of color mixing.
·Unique hat design and surface matte treatment technology, reducing the environmental impact of light on the screen and improve the contrast of the screen effectively, thus improving the display effect greatly.

Circuit Design Technology
By video image processing with deep understanding and years of video technology, we optimize the circuit design, signal transmission based on our own control system features, to ensure that the whole screen gray scale more rich and subtle and in any case can reflect the full screen details, also make sure that LED without chroma drift when at low current drive and prevent image distortion.

Non-Linear Processing Technology
·Y correction: According to the human eye's sensitivity to light and the LED display characteristics, we adopt advanced control techniques for nonlinear scan (Y corrected). transfer the non-linear change of brightness through gamma into different brightness level of the corresponding digital circuit, hence, each level of the images can be fully reflected, even detailed changes are clearly shown, which extremely enhance the image interpretation.

·Anti-Y correction: The gray scale of LED is controlled by lighting duty factor, and its brightness is linear with the driving signal. Currently, the video signal is pre-calibrated by Y. If the video signal directly sends to LED display, LED display will cause a serious distortion of gray of LED display. Hence, our company adopts anti-Y correction to the LED display screen system to eliminate image deformation.

Brightness Control Display Technology
In the highlight and low light areas with different gray-scale processing technology so that the gray scale difference of whole screen smooth. Ensure the maximum brightness of image and the picture level of clarity, detail are clear, that has better color reproduction.

System Protection Technology
·Anti-heat design: Adopt of LED, chip, power supply of the large redundancy design to ensure reliable operation at high temperatures.
·Safety Design: All units, parts and material inside the screen are chosen due to they are fire proof to ensure system safety;
·Circuit Protection Design: The standard of three protection liquid of KONKA using the protection of shipping electronic devices from the plug, welding, cleaning, and drying to the "three protection" liquid spray. The whole processing is completed by specialized equipment and the process maturity, process ·Control and stability.
·Cabinet Protection Design: Adopt sealed cabinet design to meet the cooling and achieve the protection level IP65.
·Full Screen Lightning Protection: According the lightning conditions and the characteristics of LED display products, Konka has completed the direct lightning, sideflash and ground potential to improve the comprehensive protection design.
