When we build a large-screen display platform, we usually face two choices: one is an LCD splicing screen, and the other is an LED display. These are the two most widely used screens on the market. Display products, due to the difference in technology and display effects, they also have some differences, so we mainly choose from the following aspects when choosing.
First of all, the installation environment is different
Like LCD TV, LCD splicing screen is an electronic component, but its panel is industrial grade, which can meet the requirements of continuous boot display, and the seam is very narrow, usually used for splicing, so its characteristics are destined to be scary Water and tides, so in the installation environment, the LCD splicing screen can only be used indoors, without moisture or humidity.
LED is different from liquid crystal. It uses a lamp bead packaging technology. As long as some waterproofing treatment is carried out, it can meet the requirements of outdoor installation. However, the heat dissipation of the LED is usually very large, and it needs to be cooled by an air conditioner. Equipment, otherwise the heat can not be discharged, see the influence of equipment work.
Second, the display function is different
The LCD splicing screen is a high-definition large-screen display device that can achieve 1920*1080 on a single screen. It can also achieve 4K resolution display after multiple stitching, so it is suitable for some close viewing occasions, such as conference rooms and corporate exhibition halls. Wait so that the whole screen is clearer when we watch. In addition, LCD splicing screens and decoding control equipment can also be applied to monitor display occasions, and can achieve effects such as segmentation, cross-screen, and superimposition, and can ensure the clarity of the image. LED is basically only used in the advertising field, most of which are used as large-screen displays, such as outdoor advertising large screens, shopping mall advertising screens, door-to-head screens, etc., but the appearance is small-pitch products, it is only suitable for some indoor meetings, Stage party and other occasions.
Three, after-sales rate
The LCD splicing screen is a liquid crystal display technology. It is currently the most mature display technology. It has been widely used in various display products, and it is also in the splicing field, so its panel is very stable, basically if it is not for external forces, there are few after-sales phenomena, and there is no additional after-sales service and installation cost. LED is composed of a lamp bead, so there will be a certain dead rate over time, sometimes red or black, especially when it is close to the user.
Basically, when we decide to use LCD splicing screen or LED large screen, we can refer to the above three aspects. If it is used for indoor monitoring and conference display, in pursuit of clarity and stability, choose LCD splicing screen. If it is used for LED, you can choose outdoor advertising screens viewed from a distance. Only LCD splicing screen and LED itself are divided into many categories, we need to understand more.
