A DID LCD display system consists of three main parts: the video wall, the LCD video wall processor, and the signal source. The LCD video wall processor is the core of the key technology, supporting the display of images with different pixel counts on the large screen, as well as arbitrary window opening, BSV image overlay, window zooming, and cross-screen roaming display.
The LCD video wall processor integrates multiple signal decoding units, image splicing processing units, LCD screen driving units, and power supply units. It can flexibly and conveniently form a large-screen video wall display system with LCD screens. It can operate continuously 24 hours a day.
A DID LCD video wall system is composed of LCD video wall display units, LCD video wall brackets, LCD video wall units, and signal sources. The LCD video wall display units mainly use Samsung DID LCD screens. Commonly used LCD screens for splicing include Samsung 40-inch, 46-inch, and 55-inch LCD screens; Sharp 60-inch LCD screens; LG 42-inch and 47-inch LCD screens; AU 42-inch LCD screens, etc.; LCD video wall brackets are generally divided into: wall brackets, floor brackets, floor cabinets, etc.
LCD video wall processors are generally divided into two types: built-in embedded LCD video wall processors and external LCD video wall controllers.
Built-in embedded LCD video wall processors can only be used with LCD panels. Their features include: integrated LCD driver, power supply, image display, and serial port control; all signals are processed through hardware, resulting in greater stability and reliability, shorter startup time, avoidance of virus interference, and affordable price; a leading technology.
External LCD video wall controllers have a wide range of applications, including projector splicing, LCD display unit splicing, rear projection splicing, etc.; their features include: pure hardware structure, no operating system, ready to run upon power-on; modular design, comprehensive functions; higher price; a leading technology.
