I、Product discussion
With the rapid development and application demand of LED display industry, various control
requirements for large screen control system emerge as the times require. However, due to the
limitations of the large screen control system in image processing, picture control and signal
format conversion, there are some weak links in the large screen control system of LED, which
can not meet the needs of users. The main problems are as follows:
1.The signal source access format of large LED screen control system is limited. At present,
only digital DVI signal is commonly used. Many signal sources (such as VGA) can not be
displayed directly on the large LED screen through the control system.
2.The image processing effect of traditional signal acquisition card is poor, which causes
great loss to the clarity of the picture while converting the signal format.
3.The large LED screen control system can only capture the corresponding points of the
large LED screen for display, while in some customer sites, it is necessary to display any size or
complete computer desktop screen at will.
4.The large LED screen control system can only capture the corresponding points of the
large LED screen for display, while in some customer sites, it is necessary to display any size or
complete computer desktop screen at will.
In view of the above problems, our company independently developed a number of video
processing products. The product adopts advanced control and image processing technology,
which can not only realize switching between signals quickly and steadily, but also process
multi-level pictures. In addition, the product can be controlled by keyboard and PC computer on
the device, which makes the operation simple and convenient.
