>The basis for the selection of large crystal splicing screens in the field of information publicity
>The working principle of crystal screens
The LCD screen is composed of two parallel thin It is composed of a liquid crystal module composed of glass plates. The liquid crystal module is filled with liquid crystals that are divided into very small units. The liquid crystal itself does not emit light. It relies on the backlight tube of the LCD screen as a light source. By controlling the voltage applied to each liquid crystal, the light transmittance of the liquid crystal changes to display different colors, so that the entire screen displays colorful images. image. The advantages of LCD screens include thin screen thickness, light weight, high display density (high resolution), no radiation, large unit display area, stable and flicker-free images, good color reproduction, low energy consumption and environmental protection.
In LCD drive technology, the most advanced application is as a component unit of a spliced video wall, with systematic and unified control, synchronous display, and precise splicing. Consistent brightness and color correction of each component unit in the splicing video wall system is the most critical technical requirement of the system.

> Basis for selection of crystal splicing TV wall scheme
Based on the above, it is not suitable for hotel lobby products in terms of viewing comfort. Information promotion has high performance requirements for high-definition video display, which is not suitable for the display requirements of dynamic images. However, it has the following unparalleled advantages: suitable brightness, viewing distance and viewing angle
It is professionally used for users In places such as interior display areas that do not require high brightness, in addition, its full viewing angles of up, down, left, and right can bring perfect visual effects to viewers in any direction.
Good color reproduction, high enough grayscale capabilities, and high-definition resolution Rate
With its excellent color reproduction and contrast ratio, the resolution can fully support the current full HD video signal. And the most advanced Samsung narrow-edge LCD screen can achieve the highest contrast, greatly improving The color of the LCD display is improved.

Liquid crystal display technology is one of the most excellent flat-panel display technologies at present, especially the LCD screens used in spliced curtain walls. The lamps have a service life of more than 10 hours. After working for a long time, the image There is no change in stability. LCD technology does not have any consumable equipment that needs to be replaced regularly, so maintenance and repair costs are extremely low.
For display systems, the main factors that affect its reliability are temperature, humidity, structure, interference and the service life of the system itself. The higher the heat generated by the system itself and the greater the humidity of the external environment, the more likely it is to accelerate the aging of internal components and reduce their normal service life. The more complex the structure and the greater the weight, the easier it is to increase the overall load of the system, which is not conducive to installation. At the same time, for the display system, its anti-interference ability will also directly affect the display quality and service life of the system.
The LCD splicing curtain wall of Fuyou Information Co., Ltd. is developed, designed and produced based on the requirements of security monitoring, industry and military industry. It can fully meet the requirements of uninterrupted work every hour a day and a year, and effectively ensures that the system Run stably, safely and reliably. The internal control circuits of the spliced curtain wall adopt a multi-redundant low-power design, use safety materials, and use an air eddy current heat dissipation method designed using engineering fluid mechanics to more effectively ensure the stability and reliability of the circuit.

Multi-screen image processor
The control system is the core of the entire large-screen splicing display system, which is the multi-screen image processor. All functions of the system are implemented by the splicing controller. The controller receives transmissions from the transmission equipment and converts, processes, and integrates the received signals in various ways to achieve the functions required by the system and make the signal format meet the requirements of the reproduction equipment.
The control system of this project uses Fuyou Xintong’s pure hardware splicing controller.
The main function is to divide a complete image signal into blocks and then assign them to video display units (such as rear projection units, LCD splicing walls) to use multiple ordinary video units to form a large-screen dynamic image display, which can support Simultaneous access of multiple video devices, such as cameras, satellite receivers, high-definition set-top boxes, standard computer signals, word signals, etc. The large-screen splicing controller can combine multiple physical outputs into a super-high-resolution display output after superimposed resolutions. The screen wall is formed into a logical display screen with ultra-high resolution, ultra-high brightness, and ultra-large display size, and various display functions such as window movement and scaling of multiple signal sources (signals and video signals) on the screen wall are completed. The basic functions are as follows
