Remark: If the TV screen for outdoor application, make a waterproof housing withtoughened glass front screen cover. The backside install a air-condition keep TVcooling
(10) More Instruction
1 Control PCPC with Windows98/XP system is responsible for controlling the displaying effect. It
can automatically repeat the programs in conformity to the given list, or be intervened by
hand. The display reflects the images on the PC monitor.
Through the control PC, the brightness can be adjusted manually or
automaticallyselect the non-linear corrective data according to the ambience.
Through the control PC, image contrast ratio and chroma etc can be adjusted.
The control PC can also realize various video image real-time picking, displaying, and
processing, such as:
Image noise decreasing and smoothing
Image strengthening
Chroma, contrast ratio and brightness adjusting
Moving compensation
Multi-image piling
Sound signal output

2Display controllerDisplay controller is the core device of the display, which is combined of a programmable
device and SCM system.
Main functions:
Receiving, processing and distributing the data from the control PC
Realizing the control system for the drive mode
Realizing 256 brightness ranks for each color
Realizing 8196 non-linear corrective degrees for each color
Realizing 1024 grey scales for each color, data saving or distributing
Monitoring the control PC ( power off the display while receiving abnormal signals)
Inclusive of long receiving units to realize long distance transmission
3Display mainbodyThe display is in composition of many LED modules, which are divided into
different areas, receiving the data distributed by the display controller. The sub-controllers
(scanning boards) on the back of display realize the drive logic and grey scale timing logic.
The modular structure improves the stability and maintainability of the display.
12 System functions
Technically speaking, large-screen LED display system is an electronic information
display system integrated of PC-control technology, multimedia technology and LSI. It
includes multimedia, multi-channel, and high-speed communications interface and video
interfaces of real-time transmission.
The adoption of computer networking technology makes the data production, processing,
storage and transmission more secure, rapid and reliable.
1Video display modeThrough multimedia video control technology, various video data could easily be
imported into the computer network systems, such as broadcasting and satellite TV
signals, the camera signals, VCD signals and computer animation information etc, and
thus the following functions can achieved:
Rebroadcast the broadcasting and satellite TV program
TV, camera and video etc real time display
2Serve and reflect the data in the PCReal-time display various PC data, image, and animation etc
Various choices of font style
Flexible input and display various data with multimedia software in the system

Various display modes such as image size adjusting, real-time multi-window, synch
calendar and clock, single-line text and picture, animation, VCD, DVD and multimedia
digital video
Brief news editing and displaying
Important notice releasing
Advertising etc
3Other functionsNetwork connecting port, facilitating data network connecting and controlling
Equipped with monitor camera, supervise the display effect in the control room.
Equipped with sound card with sound connecting port, facilitating connection to
broadcasting system and synchronization of sound and image
