Section 3 Solution applications Single transmitting card can supports 1280 1152@ 60Hz. So we usually use the single transmitting card solution for the normal screen. 3.1 Typical applications Fig. 3-1 typical single transmitting card application Solution Description: See Fig. 3-1, unit 1 is a computer, unit 2 is a transmitting card, unit 3 are receiving cards, and unit 4 is an environment detector. Transmitting card has two output ports: U and D ports. The transmitting cards are connected serially and you can access the Environment Detector in U or D ports. Environment detector can monitor the environment brightness, temperature and humidity in real time for each LED screen. Each port of the transmitting card can cascade 200 receiving card units at most. Features: This system is simple and flexible. It can set the screen brightness automatically according to the current environment which is measured by an 15
environment detector. So the system can make the LED screen always keep in the best working condition. 3.2 Redundancy replication application Fig. 3-2 single transmitting card port redundancy replication Solution Description: See Fig. 3-2, unit 1 is a computer, unit 2 is a transmitting card, unit 3 is receiving cards, and unit 5 is a photoelectric converter. The units are connected with unshielded twisted pair (CAT-5E) up to 100 meters; if the transmitting distance is more than 100 meters, we suggest to use optical fiber in transmitting, that means using the unshielded twisted pair to connect between unit 3s and to link between the last / first unit 3 and the photoelectric converter, and optical fiber is used only between unit 5s. The transmission distance of multimode fiber is 500 meters and the transmission distance of single mode fiber can reach to 10 kilometers. The transmitting card has two output ports port U and port D, which can back up each other. The transmitting card respectively transmits the date from port U or port D to the receiving card port A or port B. So when one transmission line has some problems, another line can back up instantly, the screen can still display in normal, this is the redundancy function. It should be noted that the redundancy function is based on the 16
output of transmitting card, if the transmitting card went wrong, the screen may display in error. Solution feature: The system supports long distance transmission, and has redundancy function, when one of the signal transmitting pathways is in error, the system can automatically switch to the other pathway, to ensure that the LED screen display keeps in normal, so that the system is more reliable. 3.3 Correction application Fig. 3-3 Correction Application Solution Description: See Fig. 3-3, unit 1 is computer, unit 2 is transmitting card, and unit 6 is SLR camera. Receiving cards are assembled in every cabin of the LED screen. The camera should be fixed on tripod and then take photographs. Solution feature: After correction, brightness uniform of the LED screen is improved. Solve the inhomogeneity of the LED screen caused by discrete of LEDs. V9A01 solution has the advantage of fast correction, easy to operate, and no loss of 17
brightness in most of gray levels. Another one is that the uniform of the LED screen wouldn t decline when changing position of cabins. 18
Section 4 Feature 4.1 Data source input Support all the VESA stander display module in SXGA 75Hz adaptive Support DVI and HDMI input 4.2 Frame frequency self-adaptive The frame frequency of the data source self-adaptive 4.3 The LED display pixel supported Supports two-color real pixel screen, three-color real pixel screen and four-color virtual pixel screen. Supports all color forms of four-color virtual pixel. Support different pixel types with the same transmitting card, the only thing we need to do is to reconfigure the parameter of the pixel type in the software LED Manager instead of modification of the logic program. If the pixel type of four-color virtual is in use, you can use LED Manager to reconfigure pixel type and set it to real pixel or virtual pixel. The same transmitting card can be shared by the screens with different pixel types. 4.4 Screen connection mode supported Line control mode is supported 4.5 Long distant transmitting GTP port supports single UTP5E as transmission medium, transmission distance less than 100 m. GTP port connects to gigabit media converter directly; choosing single-mode fiber or multimode fiber according to different distance between converters. 4.6 Control mode of the system Communication with the PC through USB port. Please use A/B type USB cable, the port A connects PC; port B connects the transmitting card. System parameters can be configured by LED Manager. When power-down, the 19
configured parameters can be kept. After power resumes, the system restore automatically to the state before power-down. 4.7 Detect fault of interface All data transfer protocols of the hardware contain checking messages. All hardware and 97059 chips can check the correctness of the input data. 4.8 The adjustment of Low gray curve Support the function of low gray curve correction Optimization algorithm reduces the unstable screen vision of low gray pictures. 4.9 Custom gray curve Provide varies gray curves to fit the requirements of environment. 4.10 Multi-mode of brightness correction Three modes can be chosen by LED Manager: manual, timing, auto brightness correction The system has the function of adaptive ambient brightness on two conditions. One condition is to choose auto brightness correction by LED Manager 2010; the other is to connect the system with an Environment detector. 4.11 Support large screen Provide general and super large screen manager tools, which support the system with several transmitting cards, thus to control super large screen. 4.12 The maximum pixel number through a single port on the conditions of the frame frequency is 60HZ and without any data packet lost. In three-color mode When the frame frequency is 60HZ and without any data packet lost, the maximum pixel number it supports is 650,000 for real pixels In virtual mode When the frame frequency is 60HZ and without any data packet lost, the maximum pixel number it support is 650,000 for virtual pixels 20
