55 inch LCD splicing screen

The frameless design of WorldCom Bell LCD makes the gap between spliced screens almost imperceptible. It can display content on multiple display units without being disturbed by annoying frames. With the help of gravity, the bracket can automatically align the panel and keep it in place at all times. In addition, WorldCom Bell supports also simplify maintenance and facilitate quick disassembly of individual panels. In terms of image quality, installation accuracy, ease of maintenance and reliability, it has taken a big step forward. Stone Bell also redesigned the structure of the panel to prevent all possible brightness changes from the center to the edge. The upgraded WorldCom Bell module can be used for faster and easier setup and maintenance.
