The LCD splicing wall is the main product of the large screen display in the room at this stage. It is composed of several patchwork modules. The interval between each screen is very small. It can even guarantee the "splicing" according to the unique technology. However, the LCD splicing wall is generally widely used In the room, why can't it be used outdoors like a led display? Today, Long Chengshengye will discuss with everyone.
First of all, outdoor display screens generally have a relatively long viewing distance and must have a high chromaticity. At present, the maximum chromaticity of the LCD splicing wall is only 700cd/m, which cannot meet the requirements of outdoor display information at all. It is an LCD splicing wall. The key reason why it can't be used outdoors is like everyone's usual mobile phones, computers, televisions, etc. If you are outside in areas where the sun is very large, it is not clear at all.
As far as the technology of liquid crystal displays at this stage is concerned, chromaticity is still a unique problem, but after all, liquid crystal displays are used to display information in rooms and outdoor billboards display information, but a large number of them still tend to LED displays.
Secondly, the outdoor display information must fully consider the conditions of rain, wind, and exposure. The LCD splicing wall itself is not a protection measure against moisture. If you need to do very moisture-proof maintenance, it will inevitably cost too much and it is not cost-effective, and the LED display screen is not. The same, it can choose a sealed shell to achieve practical effects such as moisture-proof and lightning-proof.
In terms of comprehensiveness, it is unreasonable for the LCD splicing wall to be used outdoors. Therefore, the large screen display of the LCD splicing wall that everyone sees is generally in the room, such as monitoring systems, exhibition halls, conference halls, and big data visualization. Service platforms and financial media center venues. 22.jpg
Because it has the characteristics of being suitable for 724 hours of undamaged operation, and the interface display information is more super clear than traditional projectors, led display screens and other interfaces, and close viewing will not cause blurring. , Flashing and other conditions.
