Technological Features for Hongshi Company
The brightness of display screen can be regulated in stepless control according to the lighting condition at site; the brightness for the red and green can be regulated respectively. It’s true 256 grey scale displays internally, it’s 1024 grey-scale exchanging.
Constant current drive can resolve the problem that the passed current is not consistent as constant voltage driving due to inconsistence for the internal resistance for each LED tube core. It enjoys a perfect consistence for the color of display and the colors are brighter and more vivid.
It applies the control card and picture frequency doubling technology special for the large screen in the latest design with its active scanning frequency more than 120Hz without swashing or flashing.
It applies advanced data transmission technology to support no relaying remote transmission. The control mainframe can be placed far from the screen, providing much convenience for the distribution, operation and maintenance of customer's system. It also provides special software related to remote control, and any computer in local network can control the displayed content in the display in certain automaticity.
The circuit for the screen body has a high integrity and simple structure, which reduces failure rate as well as power consumption.
With perfect cooling system design, the screen body can be effectively against rain, dust, moisture, corrosion and typhoon.
It applies the imported elements with high reliability and long service life, and use the chip for MOTOROLA、PHILIPS、NEC or ST etc in long term. Its service time is no less than ten years.
Software trend for hardware function is one of great features and advantages of our products. The user may revise the parameters as he wants, such as the screen body brightness, Gamma curve and white balance, etc. Then it needn’t to revise the hardware frequently.
New Gamma internal calibration technology and brightness regulating technology make the red, green and blue color in the display screen be calibrated respectively without changing the picture in the display.
Data extension technology and grey-scale linear switching technology make the color smooth and soft, substantially improve the image definition.
Color space conversion technology can make proper white balance effect for multiple-color LED to avoid distortion and to offer better brightness, larger visual angle and higher color resolution.
The scan control panel will receive the high speed data stream from the control unit. The scan signal will be maintained individually even though the mainframe is powered off so that the scan signal will not damage the screen.
Depending on the non-linear brightness characteristic of LED, the whole brightness of screen can be adjusted by the software in the control unit so as to display grey scale and get perfect display effect of multimedia video.
As one of the initiators of LED standard in China, Hongshi Company is a professional manufacturer of large information system engineering. With rich experiences in designing, manufacturing and implementing large information display system of Shenzhen Bao'an International Airport, Ji’nan Yaoqiang International Airport, Shenzhen Stock Exchange and Shenzhen Railway Station etc., Hongshi Company is one of few manufacturers with advanced hardware control drive technology and powerful software technology in China. A complete and strict processing, packing and transportation flow has been formed in the company to ensure high quality and good after-sale service system.
As a professional manufacturer of information display system, Hongshi Company has complete, stable and reliable system equipment. If we scraped various equipments together, the quality of system would be abated greatly. As the weak electricity engineering is a kind of investment of fixed assets, it is important to choose products from manufacturers with good image so as to ensure advanced technology, high quality, safety and reliability of equipment.
