What are the technical applications of embedded splicing controllers?
The LCD splicing screen has not been used alone, and the single-screen use of the LCD splicing screen is no different from the general display. Therefore, the embedded splicing controller is often used in the process of using the LCD splicing screen. In general, embedded splicing controllers rarely appear in the program, and only the technical installers can be contacted. Today, the editor will share with you the introduction of advanced technology to the embedded splicing controller.
The embedded splicer is also called "splicer", LCD splicer, "large screen splicer", "built-in splicer", "back small schoolbag" and "splicing processor". It is based on the LCD screen signal drive board The added operation segmentation technology, its working principle first transfers a complete original picture to the signal operation processor. The operation processor starts to lock its position in the parent picture by means of the id address encoder and arranges them in the order of binary bcd codes ( bcd horizontal coordinate: from left to right, and bcd vertical coordinate: from top to bottom) start to cut into multiple sub-pictures.
The processor directly sends the calculated data to the LCD driver board, and the driver board adjusts the parameters such as color, brightness, contrast, etc., and transmits them to the lcdic imager in lvds mode to form an image. Because the embedded splicer uses the hardware architecture digital graphics processing technology to process only one type of signal at a time, it does not require a powerful CPU core to calculate multi-channel signals. The simple single-screen splicing function provides very flexible and convenient for some customers who only need large-screen display. Until now, there is an irreplaceable position when configuring the LCD splicing screen.
However, this internal splicing device is only the processing of the display pixels inside the unit. The result is a composite display image, which cannot solve the signal high-resolution stitching and multi-window signal processing at any position and any size. More applications are in the promotion of a single signal. It is used in the simple multi-picture processing application spliced by the screen and the unit or adjacent unit. It is also used in conjunction with the first-generation pci industrial control type splicing controller in the high-end multi-window signal control room.
In addition, because the embedded splicing controller is a pure hardware architecture, there is no windows operating system, no crash, no black screen, no flower screen phenomenon, the original motherboard bus design is adopted; the single unit supports up to 144 high-definition signal inputs and 144 display unit outputs , No cascading required; supports multiple video signal sources such as rgb, high-definition video ypbpr, dvi, composite video, and ultra-high-definition dvi signal input (4kx2k); bus bandwidth can reach 180g; adopts original motherboard bus design, supports Input signal characters are superimposed to facilitate identification of each window on the large screen.
Support at least one-to-many, many-to-one, many-to-many display modes and zoom, roaming, brightness, contrast, saturation, hue, sharpness, still frame and other display effects control; support rs232 serial port and network tcp / ip control, support bsv-pdu processor control software, and completely open control protocol; support rgb and dvi output at the same time, support output channel dual backup, support output channel logic secondary programming support multiple video input modes; and embedded splicing controller control system application With good stability and reliability, the average time between failures is greater than 50000 hours, with power supply redundancy backup, a certain protection scheme must be adopted for the key components of the control system to ensure the normal operation of the system; the embedded splicing controller system completes any display The switching time between modes is not more than 2 seconds, and each scene mode can be switched regularly.
The embedded splicing controller is mainly used for general display requirements and is currently the most popular LCD splicing screen configuration device. Of course, it can still be replaced by an external image processor, nor can it support LCD splicing screen picture-in-picture and window roaming. However, it is still necessary to understand the embedded splicing controller before purchasing the LCD splicing screen.
