What’s the Difference Between LED transparent video wall and LED Grid Screens?
LED transparent screen products continue to evolve and innovate, and their applications on windows, stages, and glass curtain walls are gradually increasing, providing audiences with more immersive visual experiences. However, many people are not very familiar with transparent video wall and often ask about the difference between LED transparent screens and grid screens.
In reality, LED transparent video wall and grid screens are related; grid screens are one type of product within the category of LED transparent screens. You could say that grid screens introduced the concept of LED transparent screens. Currently, common types of LED transparent screens include LED grid screens, LED film screens, and LED ice screens. Film screens and ice screens are more challenging in terms of production processes compared to grid screens, so LED grid screens are generally more affordable.
In terms of appearance, LED film screens and ice screens have better transparency and display effects compared to grid screens. They are thinner in appearance and easier to install, as they can be directly attached to glass curtain walls or windows. Grid screens, on the other hand, have a steel frame structure, making them relatively bulky but offering higher stability. LED grid screen prices typically range from 3000 to 5000 yuan per square meter, while LED film screens and ice screens are priced at around 5000 to 10000 yuan per square meter, with specific prices depending on the product specifications.
When purchasing transparent video wall, it’s important to assess the product’s quality. You can initially evaluate the quality based on factors such as brightness, color, stability, waterproofing, and flame resistance. From a more professional perspective, you can assess product quality by examining the materials used in the LED transparent screen, such as the IC, LEDs, control cards, and other components.
The Eight Factors That Determine the Quality of LED Transparent Grid Screens
The popularity of LED transparent video wall, a novel display device with high transparency and a more three-dimensional display effect, has been on the rise in areas such as shop windows and curtain walls. However, LED transparent screens are still in the phase of research and improvement, and the production processes of some LED display screen manufacturers are not yet perfect, resulting in concerns about product quality.
The quality of LED transparent video wall is primarily determined by the following eight factors:
- Manufacturer of LED transparent video wall: Try to purchase from reputable businesses or manufacturers. Based on market feedback from the past five years, products from these manufacturers tend to have stable quality, fewer after-sales issues, and higher customer satisfaction.
- Choose a Professional Brand: When selecting an LED transparent video wall, it’s essential to choose a professional brand rather than necessarily opting for the most prominent or largest brand. Some well-known manufacturers may not have been in the field of transparent screens for long, and their capabilities may not be as strong. Large-scale manufacturers often produce various types of LED display products, whereas manufacturers focused on LED transparent screens are generally medium-sized. Given the limited market size, they concentrate on specializing in this area. From market feedback, some of these manufacturers also have excellent reputations.
- Look at the Model of the LED transparent video wall: A smaller pixel pitch and higher pixel density result in greater clarity. For example, P3.91 LED displays are generally suitable for small areas up to 5-30 square meters, P7.81 LED displays are suitable for areas between 10-50 square meters, and P10.42 LED displays are suitable for areas over 80 square meters.
- Consider the Brightness of the transparent video wall: Lower brightness is suitable for indoor use, with 1000 nits generally being sufficient. If the indoor lighting is bright, a brightness of around 1500 nits should be adequate. In semi-outdoor environments, brightness levels are typically between 2500-3500 nits, while for outdoor use during the day, where lighting is stronger, brightness is controlled at 4000 nits or above.
- Examine the LED Chip Brand: A good chip brand exhibits high luminous efficiency and uniformity. Poor-quality chips may become hot to the touch after being lit for some time.
- Evaluate the Power Supply Brand: A high-quality power supply will have a refined appearance, with well-arranged internal components. It should have high energy conversion efficiency to meet energy-saving and environmental requirements while saving electricity and costs for users. High-efficiency power supplies have lower temperature rises, which affect the stability and lifespan of the power supply.
- Check the IC Brand: Energy efficiency is an important criterion for evaluating driver IC performance. Optimizing IC algorithms and design to reduce operating voltage and current can minimize power supply voltage, reduce heat generation, and improve LED transparent video wall performance.
- Assess the Solder Joint Quality: Full solder joints indicate good soldering processes and high brightness. Serious issues, such as virtual solder joints, can lead to poor contact and troublesome maintenance.
When purchasing LED transparent video wall, it’s essential not to focus solely on product prices. The price of the product is closely related to the quality of raw materials. The pricing system for LED transparent screens is relatively transparent, so do not be swayed by unscrupulous sellers offering low prices for inferior products, as this could affect your long-term usage experience.
