Currently, LCD video walls on the market can be divided into many different types. Among them, the seamless video wall is undoubtedly one of the most widely used and highly rated. Some people may be particularly curious about this: is this type of video wall truly seamless? Let's look at the following explanation:
First, we need to clarify that the purpose of introducing this type of video wall is actually to solve the physical bezel problem of LCD video walls. Since the production of LCD panels cannot achieve a bezel-less design, seamless video walls can only achieve seamlessness through an indirect technology. Specifically, the principle is mainly to artificially remove the bezel around the LCD screen and add a specially designed LED light source above the bezel, which contains small-pitch LED beads. This allows it to be perfectly integrated with the LCD screen, achieving unified light emission, thus appearing "seamless." This is also known as LED light source compensation technology.
Therefore, it's important to understand that this type of video wall is not bezel-less during panel production; the technology is not yet mature enough for this. In fact, it achieves the effect of removing the border through a post-processing light source compensation. Although it is an indirect method, we cannot deny that the overall display effect is still quite ideal.
