Many customers find it difficult to make a choice between the LED transparent screen and the LED grid screen. They don't know which product to use in their projects. This is mainly because they don't know the characteristics of the two products very well. Here, jucaiyuan Xiaobian compares the similarities and differences of the two products. You won't have these troubles after reading them.What is the difference between LED transparent screen and led grid screen?The two have the same points:
1. The design principle is the same:Led grid screen is also called LED light bar screen. Like transparent LED display screen, it adopts hollow out design on the basis of traditional LED display screen to remove redundant parts and provide product permeability, which makes the light transmittance of the position where the two displays are installed higher.2. The installation position has intersection:
Both of them are installed with glass curtain walls. The main purpose is to make use of the characteristics of high transmittance of both of them and not affect the indoor daylighting. This is mainly because the impermeability of the traditional outdoor LED display screen suppresses the indoor light and is not conducive to the health of indoor staff, As early as 2015, some European countries have issued relevant policies to prohibit the installation of outdoor LED displays without permeability.Differences between the two:1. Different lamp beads are used: the LED lamp strip screen generally has a large production area, so the point spacing is relatively large, and the point density is relatively small. However, when it is used in outdoor environment, it needs to highlight products, so it is generally made of straight lamp beads to ensure the highlight characteristics of the screen. The LED transparent screen is installed indoors and viewed outdoors. The point density is generally large, the point spacing is relatively small, and the precision is higher, so it is generally made of SMD lamp beads.
2 the installation environment is different: the LED light bar screen is installed outside the screen body, while the transparent LED display screen is installed in the indoor environment.3. Different waterproof levels: the LED light bar screen continues the high-level protection characteristics of outdoor LED display screen because it is installed in a pure outdoor environment, and the general protection level needs to reach IP65; Because the LED transparent screen is installed in the indoor environment, it does not have high requirements for the protection level. It is generally ip34. Unless it is in the position where the glass trestle is used, nano protection must be carried out to improve the protection level.
4. Different weight: because the LED light strip screen needs to provide the protection grade, it needs to adopt the glue filling waterproof process, which will increase the weight of the light strip itself. Because the light strip itself is heavy, the box must be made of cold-rolled steel plate or die-casting aluminum, which will lead to the heavier weight of the whole screen. Generally, the single square weight is about 20kg, but this process does not exist for the LED transparent screen, The light bar will be thinner. Some Shenzhen adopt frameless design, the screen body is lighter, and the weight can be as light as 12kg / m2, or even lighter.
Zhongrun optoelectronics focuses on high-end creative LED display screens, and can provide customers with these two products to meet the needs of different customers. However, the LED transparent screen greatly exceeds the LED strip screen and becomes a more popular product.What is the difference between LED transparent screen and led grid screen?Advantages of LED transparent screen:
Ultra high transparencyThe transparency of the highest pixel can be as high as 75% - 95%, and the screen can hardly be seen outside the line of sight of 10m.Easy to assemble and debug
You can quickly and easily fix the module on the bracket with both hands, or you can customize the installation.Lightweight and easy to transportIncluding all structures and power supplies, the weight per square meter is only 12kg, which is only half the weight of the traditional screen. The ultra light weight is very convenient for transportation and saves cost.
High brightness and low energy consumptionUsing customized high brightness and high luminous efficiency LED chip, the maximum power consumption is only 800W when the screen brightness is 5000cd . The energy consumption of LED is not only lower than that of projection and LCD display, but also the high brightness of the screen can ensure that it is still clearly visible in the daytime sunshine.Easy maintenance:
Long service life, only need to replace the light bar, without replacing the whole module. Use outdoor standard encapsulated LED lamp, UV resistantAdvantages of LED grid screen:Light weight and small wind load
The light weight is due to the screen grid, which enables the LED display to ventilate, so its wind load capacity is very strong.High efficiency and low power consumptionThe real energy saving comes from: LED lamps with high brightness and high luminous efficiency and power supply with high conversion efficiency.
Highly integratedHighly integrated (built-in power supply and receiving card, each unit can work independently; one line of power supply and signal is connected),IP67 high protection grade
The concept of IP67 is immersion waterproof, that is, the overall immersion of the product. Compared with IP65, it can be described as a dimensional gap.Easy installation and maintenanceNo steel structure installation, no air conditioning, front installation or rear installation.
Led grid screen is a grid shaped LED screen composed of light bars, also known as LED light bar screen. It is mainly used in outdoor wall, glass curtain wall, building top and other fields. Led grid screen breaks through many restrictions of conventional LED display screen on building body and wall, making the project more flexible and selective.The service life of LED grid screen is between 2-3 years. It is a lighting LED display product. It is generally used indoors, because its permeability reaches 30-60% and the overall power consumption is relatively low. It adopts natural ventilation and heat dissipation, but the relative temperature rises and has strict requirements on the installation environment. The advantage is that the control box and installation structure are integrated and the installation space is small.
