1. Completely Compatible with the Seventh Generation Control System
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. Supporting 210 colors
The seventh supports 28 colors: 28*28*28=16777216 kinds of colors.
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.
So the coloring number of the eighth is 64 times as much as that of the seventh.
3. The intelligent connecting function
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. The intelligent supervision function
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. Company Logo Showing
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. Supporting more scan mode
The seventh supports 1, 2, 4, 8, 16 scan mode, the eighth supports 1, 2, 3, 4, 5, 6, 7, 8, 9. 10, 11, 12, 13, 14, 15, 16 scan mode.
7. Supporting more modules
The seventh supports modules with the width: 2pixels, 4 pixels, 8 pixels, 16 pixels, 32 pixels, 64 pixels.
The eighth supports all the modules with width within 64 pixels. That is from 1 pixel to 64 pixels.
8. Supporting cut-up function
Each receiving card max supports 1024 pieces cutup, for non-conventional type display or text display use.
9. supporting empty pixel insert
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. Supporting PWM driver chip
Need to use particular driver chip
Make the display effect going perfect
11. Supporting hardware pixel by pixel correction
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. Supporting pixel supervision function
Need to use particular driver chip
Dynamically check the bad pixels on the display.
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 and Unit box by Unit box Correction Function
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. Intelligent Identification Function
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. Gray level 0—Gray Level 66536 (64K) are Optional
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. Optional Refresh Frequency, Synchronous function
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.
18. Super loading capacity
Full-color receiving card with gray level 4096 (Model 4K) and refresh frequency 180HZ can support 512*128; full-color receiving card (model 16K, only for static) with gray level 16384 and refresh frequency 300HZ can control 160*64,.(Remarks: the drive board must realize high frequency 30MHZ)
19. Double network cables switch automatically
The A and B ports of the receiving card can be both used as input ports or output ports. Users can adapt two computers to control a display at the same time, when one is out of order, the other will replace it automatically; Users can also use one computer with double network cables to control a display, when one is out of order, the other will take place of it automatically, making the display work normally all time.
20. Multi-display synchronous and combination functions.
Supporting one sending card to control multi-display, and the multi-display can be willful combination, synchronous display, and independent play.
21. Brightness 256 Levels Automatic Regulation
The function of brightness 256 levels automatic regulation can make the display brightness regulation more efficient.
22. Voice Transmission Function
Model 702 integrates the voice transmission, and requires no audio cable to transmit audio signals to the display. Double 24bits and 64KHZ hi-fi digital analogy and modulus switch to transmit the voice, making display achieve the perfect video effect.
23. Upgrading Program Online
If program of receiving card needs to be upgraded, just open the display power, and upgrade it through Led Studio, no need to remove the receiving card from the display.
24. No Toggle Switch
No toggle switches on the receiving card, all the setups are set through Led Studio.
25. Test Function
Receiving card has the test function, no sending card needed; can test the display directly, such as bias, gray level, red, green, blue, etc. many kinds of test modes.
26. Super Long Transmission Distance
The max transmission distance is 170M (actual measure); normal transmission distance is 140M.
