1、Product discussion
With the rapid development of the LED display industry and the continuous expansion of application
requirements, various control requirements for large-screen control systems have emerged. However, due to the
limitations of the large-screen control system in image processing, picture control and signal format conversion,
the LED large-screen control system has some weak links and cannot meet the needs of users. The main problems
are as follows:
1.The signal source access format of the LED large screen control system is limited. Currently, only digital
DVI signals are generally used. Many signal sources (such as VGA, etc.) cannot be displayed on the LED large
screen directly through the control system;
2.The traditional signal acquisition card has poor image processing effect, which causes great loss to the
clarity of the picture when the signal format is converted;
3.The LED large screen control system can only capture the image corresponding to the number of points on
the LED large screen for display, and in some customer sites, it is necessary to display the screen of any size or
complete computer desktop at will;
4.With the continuous reduction of the distance between the LED screens and the continuous increase of the
number of screen points, the era of single-card loading and single-screen display of a single screen will soon cease
to exist, and more application requirements and display requirements will be highlighted. LED large screen control
system It needs better cooperation with other peripheral equipment to fulfill the needs of customers.
In response to the above problems, our company has independently developed a variety of video processing
products. The product adopts advanced control and image processing technology, which can not only realize fast
and stable switching between signals, but also perform multi-level processing on the screen.
KLS24 is a control processor designed for live performance LED large screen. Adopt the industry's top design
technology, in line with international and industry standards. Pure hardware FPGA design architecture, all boards
of the product adopt modular design, and input boards can be freely selected. It is a 3U device that supports
4K@60Hz input in the industry.
The whole machine has 13.8 million pixels of custom loading, which can meet the needs of most of the scene.

Screen Resolution The maximum resolution that the can output for each outlet, typically greater
than the resolution of each card or display.
Row and Columns set on your own, above the layout diagram 1920 and the on the left 1080 the
can be modified according to the actual number of load points, double-click the value to modify.
For example: Screen size is 6016*2080 , with six send cards, with load size and arranged as
shown in the following figure:
Then, the screen parameter settings interface requires the following settings:
