Transparent LED Display Buying Guide: How to Choose Size and Model
Transparent LED displays have become a rising star in the display field, and naturally become one of the popular choices for users in many industries. However, in the actual demand process, factors such as model, size, and viewing distance need to be comprehensively considered, which undoubtedly makes it more difficult for users to recognize. Let’s talk about the factors that need to be paid attention to when choosing LED transparent display.
It is impossible to have both fish and bear’s paw. Transparency and dot spacing are the dilemma for transparent screens. The higher the permeability, the thinner the arrangement of the lamp beads. At present, the maximum transparency of the transparent screen has reached 85%, and the minimum point spacing is 2.78mm. For transparent screens, the future is to further increase the pixel density and transmittance to reach the ideal balance point.

Transparent LED Display Selection Guide and Points to Note
1. The dot pitch, size and resolution are closely related, and product selection should pay attention to the application
In the current small-pitch LED market, permeability, dot pitch, large size and resolution are the key points of manufacturers’ technical PK. In practice, these factors also affect each other, and the specific dot spacing must be matched with the appropriate transparent screen size to achieve the best display effect.
As shown in the table above, a product with a pitch of 3.977.81mm reaches a full HD resolution of 1920×1080, and the corresponding screen area is 57.1 square meters. Even if there is no base, if the user’s application space is limited, the installation difficulty will be greatly increased, and the cost will naturally increase. Furthermore, if the viewer wants the best viewing experience, the optimum viewing distance must be selected. In practice, the best visible distance = point spacing/0.3. The distance is close, generally 2.785.56mm, and the distance is 3.97*7.81mm.
In the practical application of transparent LED display, it is not that the smaller the dot pitch, the higher the resolution, the better the actual effect, and the screen needs to be considered comprehensively. size and application space. At present, the smaller the transparent screen dot pitch and the higher the resolution, the higher the price. If the application environment is not fully considered when purchasing the product, it may lead to excessively high prices and the inability to achieve the expected application effect.
2. Selection of LED transparent screen brightness
Full indoor display. Including: indoor stage, exhibition hall, conference room, etc. The indoor light is dim, and the brightness of the transparent LED display should be controlled between 800-1500nits. It is recommended not to exceed this brightness range. If it is too bright, it will appear too dazzling, affect the viewing effect, and also consume more electricity.
Semi-outdoor display. Including: shopping malls, sales offices, etc. The semi-outdoor light environment is better than indoors, and the brightness selection should be controlled at about 2000-3500nits to ensure the normal display effect of the transparent screen.
When the LED transparent screen faces no sunlight, it is perfectly satisfied according to the customer’s environment of 3000CD-4500nits; when the LED transparent screen faces the sun, the low-brightness transparent screen will appear blurred pictures due to insufficient brightness. The brightness selection should be around 5000-6000nits to meet the normal display effect in a strong sunshine environment.
3. Large-size products must fully consider maintenance costs
In practical applications, not only the high purchase cost but also the maintenance cost should be considered when selecting large-size products. Although the theoretical life of LED lamp beads can reach 100,000 hours, because high-density LED transparent screens are mainly used in indoor applications, the products are required to be light and thin, and the thickness should be low. Although the transparent screens do not require cooling fans and air conditioning auxiliary equipment, the large size The application of the product will make it difficult to dissipate heat, and the probability of local failure will be high. In actual operation, the larger the screen size is, the more complicated the maintenance will be, and the maintenance cost will increase accordingly. Therefore, for large-size products, users must choose on demand.
4. The combination of signal transmission equipment cannot be ignored
The signal compatibility of the LED transparent screen is very important. If the signal access requires a variety of requirements, the number is large and the location is scattered, it usually includes video signals in H.264, 720P, 1080P and other formats. When purchasing a product, you should avoid paying attention to the product unilaterally. The resolution must be fully considered whether the existing signal equipment supports the corresponding video signal.
