1. The eighth generation is developed based on the seventh. Compared with the seventh, the eighth has all the functions of the seventh. Moreover, the eighth is more functional, more powerful, more stable and more reliable. 2. The eighth supports 210 colors: 210*210*210=1073741824 kinds of colors. It needs to work with our video processors using the 30 bits TTL. 3. Without resetting the configurations, the receiving cards (including spare ones) of the same LED display/cabinet can be randomly exchanged or replaced, for they will automatically recognize the showing area and content they are responsible for. 4. In each receiving card, there is a temperature sensor and four fan-power-output-ports. The speed of the fans is under wise controlled according to the warming value of temperature set by users. 5. If the power of the sending card is not turned on, the monitor the PC will automatically show the preset company picture. The pixel of the picture will be 128*128, the coloring number 16K. 6. Supports 1, 2, 3, 4, 5, 6, 7, 8, 9.10, 11, 12, 13, 14, 15, 16 scan mode. 7. Supports all the modules with width within 64 pixels. That is from 1 pixel to 64 pixels. 8. Each receiving card max supports 1024 pieces cutup, for non-conventional type display or text display use. 9. The eighth can be set to insert one or more empty pixels every X pixels. This function is applying in non-conversional type display. 10. Need to use particular driver chip Make the display effect going perfect 11. Need to use particular driver chip. By changing the current for the LED, adjust the color, wave and brightness of the LED. Make the effect of display pixel by pixel correction better. 12. Need to use particular driver chip Dynamically check the bad pixels on the display. 13. Veritable Giga technology. One sending card can support the max pixels: Model701: 1280*1024; Model702: 2048*640; Two cards are cascaded: 2048*1152. Single network cable supports the max pixels: Model701: 1024*640, 1280*512; Model702: 1600*400, 2048*320 14. Pixel by pixel correction supports four kinds of correction modes: Single pixel, 2*2pixels, 4*4 pixels, 8*8 pixels; And the max correction is 6144 pixels/module, and brightness 256 levels for red, green, blue. Every unit box correction is used to adjust the chromatism among every unit box; And brightness 256 levels for red, green, blue. 15. The intelligent identification program can recognize every kind of scanning mode and every type of signal trend of all kinds of double-color, full-color (real pixel and virtual pixel) drive boards, and the accuracy rate is 99%. 16. Users can adjust the gray level from 0 to 66536 levels according to requirement of displays, making the display achieve the most desirable effects. 17. Refresh frequency are adjustable from 10Hz to 3000Hz, and the refresh frequency and phase-lock function can make the display refresh locked at integral multiple of that of computer display, avoiding the image to been torn, and ensuring the image to be perfect. The phase-lock synchronous range is from 47Hz to 76Hz.
