The LCD splicing system is composed of a liquid crystal splicing display unit, a liquid crystal splicing stand, a liquid crystal splicing controller and a signal source, and the liquid crystal splicing controller is divided into a built-in and an external controller, and the built-in is called a built-in embedded liquid crystal splicer. The splicer is also called “splicerâ€, “LCD splicerâ€, “large-screen splicerâ€, “built-in splicerâ€, “back small schoolbag†and “splicing processorâ€. It is specifically designed for LCD panels and integrates LCD drivers. Power Supply, image display and serial port control; all signals are processed by hardware, more stable and reliable, start-up time is shorter, virus interference is avoided, and price is affordable.
The working principle of the embedded splicer firstly transmits a complete original picture to the signal operation processor, and the operation processor starts to lock the position in the parent picture in the manner of an ID address encoder, and is arranged in binary BCD code order (BCD level Coordinates: from left to right, and BCD vertical coordinates: from top to bottom) Begin to calculate and cut into multiple sub-images, the processor will directly send the calculated data to the LCD driver board, the driver board will be the color, brightness, contrast and other parameters After adjustment, it is transmitted to LCDIC imager in LVDS mode to form an image. Since the embedded splicer uses 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 operate on multi-channel signals. The simple single-screen splicing function provides very flexible convenience for some customers who only need large-screen display, and it has an irreplaceable status when the current LCD splicing screen is configured. However, this internal splicing splicer is only used to display pixels inside the unit. Processing, the result is a composite display image, can not solve the signal high-resolution splicing and arbitrary size multi-window signal processing, more applications are in a single signal advertising display and splicing by unit or adjacent unit simple multi-image processing Use on the application.
The embedded splicing controller is generally not used alone, and is mainly configured to display devices that work together. The embedded splicer is the most suitable component of the LCD splicing screen. In practical applications, it can also be replaced by a peripheral image processor. Currently, LCD splicing screens with embedded splicing are widely used, and the liquid crystal splicing controller has a large screen and strong visual impact, and has a good effect of display, demonstration, advertisement, and publicity. Therefore, no matter which part of the LCD splicing screen, it plays an important role in order to make the effect of the LCD splicing screen more perfect. Emperor AiDi Electronics specializes in producing LCD splicing screens, and is the most professional supplier of LCD splicing screens in China. As a professional supplier, it is obliged to allow customers to better understand the working principle of LCD splicing components, professional and technical guidance, and customers are satisfied. As a user, it is also possible to properly understand the principle and prepare for a better selection of splicing screens.
The brief introduction of the security monitoring equipment concept Pan/Tilt/Zoom represents the omni-directional (left/right/up and down) movement of the pan/tilt and lens zoom and zoom control.In the scene range monitored by the camera, when the moving target appears, the user can manually lock (for example, lock the target by mouse click) or the preset position automatically triggers a certain moving target to trigger the PTZ Camera to perform autonomous automatic PTZ tracking. The pan/tilt of the PTZ camera is automatically controlled for full-scale rotation, and the visually-oriented automatic tracking of the locked moving target is performed to ensure that the tracking target continues to appear in the center of the lens. The automatic PTZ tracking module makes up for the shortcomings of the fixed camera's narrow field of view and is a necessary function for a complete safety monitoring system.
