256 grayscale display led by the control system: multimedia card, driving long-term, frame controller and display unit constituted. Multi-media card is the main functions of the computer will be able to display digital content (also completed vga card function), as well as to external video input signal sampling, into a digital signal output for the use of display. Card is to drive long-term multi-media card output signal is converted to digital signals RS422 interface to facilitate long-distance transmission. In the main control computer and display of the distance away (350m), to adopt such a differential transmission can be reliable. For the five categories of twisted-pair transmission medium.
Director of the frame to display the core unit, the completion of the main functions include: receiving data, data processing, data storage, data distribution, the realization of gray, visual and amended regulation, and so on. Due to the realization of the function of the complexity, variety of content control, which uses large-scale programmable devices, highly integrated circuits, frame controller output to send the distribution division of the gray-scale display data signals, signals are transmitted in parallel, and therefore transmission Faster frequency.
Of the control system of the most prominent features are: a high concentration of control logic, and a high degree of integration. The display shows the front-end module includes only the main part of the drive circuit, even if the color is functional by the completion of the reunification of the master, the module is extremely simple circuit has greatly improved the reliability of the screen body, and maintainability.


Performance of the system to achieve:
1, and a gray: the real color of every 256.
2 modes: full-track display mode to support high-resolution 1024x768 mode.
3, refresh rate: frame refresh rate is greater than 200hz, the screen is extremely stable, flicker-free flu.
4, frequency: The frequency of up to 64mhz, the future of left a lot of room for improvement.
5, work: The latches work, that is, the use of video recorders transcription has also become clear.

Features:

Rich in color: two color (red, green) cells showed that board, red, green and gray 256 constitute the 65,536 kinds of colors, so that the electronic display screen to achieve color-rich, high-saturation, high-resolution display, fast The dynamic image;
High-Brightness: ultra-high brightness of the LED, long-distance is still clearly visible; good effect: non-linear correction technology, the image clearer, stronger sense of hierarchy;

Reliability: distributed scanning technology and modular design, reliability, stability higher;

Display mode diversification: support for multi-display mode;

Easy to use: General video player software, so that the system is very convenient.

The scope of application:

For the stations, airports, ports and other transportation industries as a guide system; in the banking, real estate, stock, etc. to carry out the exchange rate, stocks, futures, real estate transactions to wait for the display of information, also in shopping malls, recreation centers, the Post and Telecommunications, Hotels, traffic control, such as the environment play an important role.
