Whether it is a glass curtain wall LED transparent screen or a window LED transparent screen, it generally refers to a hard light bar transparent screen. In addition to the different application areas, what is the difference between them? Lianman Optoelectronics takes you to understand. First of all, in terms of structure, they are all composed of light strips, light boards, power supplies, and IC cards. The display principles of both are the same, and images are displayed through the brightness and color changes of LED lamp beads. But they mainly differ in 4 aspects:

1. The difference in appearance

The glass curtain wall adopts the LED transparent screen of the engineering series, so the structure is required to be stable. Generally, the LED transparent screen with a frame is used. will drop by about 5%. However, the use of side-emitting products can make up for this defect and improve the transparency to a certain extent. And because it is viewed from a head-up or upward angle, the effect will be better. For the window LED transparent screen, the borderless LED transparent screen is generally selected. This structure is simpler and the transparency will be higher.

2. Differences in playback accuracy

The glass curtain wall LED transparent screen chooses the model of P10 and above, because the screen area is large, generally more than 100 square meters; viewing is far away, generally 15 meters away, the display effect is very good; therefore, the screen accuracy is not high. The window LED transparent screen generally has an area of no more than 50 square meters, and the viewing distance is relatively close, generally between 3 and 20 meters; therefore, the screen accuracy is high, and the P3.91/7.81 model is usually recommended. In addition, there are requirements for permeability, which should not be too low, so that the furnishings in the store cannot be seen clearly, and the indoor lighting will be affected. Therefore, it will be mentioned that a borderless LED transparent screen will be used.

3. Differences in brightness requirements

The glass curtain wall LED transparent screen is for outdoor display. In terms of brightness, it is usually required to reach about 4000CD. If the installation environment is directly facing the sun or the light is strong, the brightness will be higher, so as to ensure that the picture can be seen clearly during the day. Window LED transparent screens are usually installed in indoor environments or semi-outdoor environments. If it is an indoor shopping mall window, the brightness is usually 800~1600CD. If it is at the door, the brightness requirement will be higher. Usually, the brightness is 1500~2500CD.

4. Differences in installation methods

The glass curtain wall LED transparent screen adopts a fixed method. The box frame is fixed on the glass curtain wall keel by means of composite bolts or combined hoop pieces, and is installed on the inner side of the curtain wall for outdoor display and playback. will move. The window LED transparent screen is usually hoisted or fixed. The former screen is installed by hooks and hanging beams, and the boxes are connected by quick locks or connecting pieces; ; But usually there are many ways of hoisting.

Summary: In addition to the different application fields, the glass curtain wall LED transparent screen and the window LED transparent screen are different in appearance, playback accuracy, model and installation method. But they all belong to the subdivision products derived from the LED transparent screen. Everyone chooses products reasonably according to the actual use environment, viewing distance, and use needs.
