The LED transparent screen display often refers to the hard light bar transparent screen, which has the characteristics of thinness, transparency, and transparent and beautiful playback images. It is an effective extension and expansion of the application of LED display products, mainly used in architectural glass curtain walls, showcases and other fields. The following will take you to know the LED transparent screen from 5 aspects of production, principle, technology and application:

1. Technical principle of LED transparent screen display

The principle of LED transparent screen is the same as that of conventional LED display. The LED power supply provides power, the control system is responsible for conveying instructions, the driver IC provides the display program, and the LED lamp beads are responsible for displaying various information. A complete LED transparent screen unit is fixed by the PCB board and the bottom cover, which is what we call the box. However, the box panel adopts innovative technology in structural design and related processes. The light strips are one by one, designed as a hollow structure, just like the louver structure, which makes the screen transparent, which is also the largest and the largest LED display. s difference.

In terms of playing content materials, in addition to the effect of conventional LED displays, it can also play transparent images, which is its biggest advantage. Since the black part does not emit light during playback, the effect is as transparent, so the background color of the advertisement content can be replaced with black.

Second, the production of LED transparent screen display

The main components of the LED transparent screen are: light board, power supply, control card, and connection light. The main process of LED transparent screen production is as follows:

1. SMD process

The LED lamp beads are attached to the light strip of the PCB board to form pixel points. The pixel pitch we often say is the distance between two adjacent lamp beads, and the resolution is the number of lamp beads per unit area. When patching, pay attention to the light, don't stick it backwards, don't stick less.

2. Solder

Check whether the patch of the lamp board has a lamp drop or a virtual welding, etc.

3. Installation of the box frame

Align the finished light board with the box frame and screw it well. The production process flow of LED transparent screen driver board is: patch, driver cable connector, power connector welding, capacitor welding, and driver IC welding.

4.QC inspection

The driver board is inserted into the lamp board, welded, and tested by QC. Including the lighting aging test for 72 hours, including 48 hours of red, white, blue, and green light, to check the lamp beads that are soldered or necrotic for repair and replacement. After playing the video content for 24 hours, if the color cast and brightness are found inconsistent, the balance adjustment will be made. Ensure that the LED display is perfectly presented and runs stably before shipment.

3. How much is the LED transparent screen per square meter

How much is a square meter of LED transparent screen, which actually refers to the price of the screen, and according to market research, the price of LED transparent screen is mostly concentrated in 5000~10000 yuan/㎡.

The main factors affecting the price of LED transparent screen are as follows:

1. Model spacing

In the case of the same material, the smaller the spacing, the higher the price of the LED transparent screen. Take the Lianman Optoelectronics HY-7.8 and HY-10.4 models as a comparison. The former has a dot pitch of 7.81mm, the latter has a dot pitch of 10.4mm, and the pixel density is 16436dot/m² and 9246dot/m² respectively. That is to say, one square meter of HY-7.8 screen requires 16,436 lamp beads. The more lamp beads used, the higher the cost. Therefore, in the LED transparent screen display project, the cost of lamp beads accounts for about 60%.

2. Lamp bead brand model

Choose the right brand of lamp beads according to your needs. And the type and purpose of the lamp beads are also very important. If your LED transparent screen is used in indoor environment display, the brightness of 1000~1500cd can actually meet the demand; if it is a semi-outdoor environment, the brightness is 2000~3500cd; if it is a full outdoor display, the brightness is 4000~5500cd. Be sure to choose the brightness according to your own display needs and the use environment. Under normal circumstances, high-brightness lamp beads are more expensive.

3. Structural process

At present, LED transparent screens are divided into two types: side-emitting and positive-emitting. The former adopts the process of front-mounted lamp beads, and the lamp beads are welded to death, and the display consistency is good; Plug and unplug. The price of the two screens will also be different.

Other costs include: power supply, driver IC, accessories (wiring, power distribution cabinet), transportation, and installation costs.

Fourth, the installation of LED transparent screen display

The installation method of LED transparent screen is different due to different application places. But there are mainly several ways of fixing, hoisting, and seating:

1. Floor mount

Common in glass windows, exhibition halls, etc., the screen area is not large and the height is not high. It can be simply fixed at the bottom. If the height of the screen body is high, then it needs to be fixed up and down behind the screen body to realize the fixation of the screen body.

2. Frame installation

The box frame is directly fixed on the glass curtain wall keel by composite bolts, only a small amount of steel structure is required, and it is mainly used in the field of architectural glass curtain walls.

3. Hoisting installation

This installation method must have a suitable installation location, such as a beam above. Standard hangers can be used for the indoor concrete roof, and the length of the hangers is determined according to the site conditions. The indoor beams are hoisted by steel wire ropes, and the outdoor and the screen are decorated with steel pipes in the same color.

Five, LED transparent screen display market analysis

The LED transparent screen display integrates the advantages of the conventional outdoor LED display and eliminates the problem of urban aesthetics. When it is not lit and played, it is better to hide yourself without destroying the harmony and beauty of the original environment. Since it adopts a new form of indoor advertising and outdoor communication, it is a good way to avoid the approval of outdoor advertising.

With the increase in market demand, the continuous optimization of LED transparent screen technology and products, and even the emergence of interactive technology, further brings the charm of experience. With the continuous reduction of dot spacing and the improvement of transparency and stability, transparent LED displays have gradually occupied the market with high-definition transparency, and even occupied an important position in the application field of glass curtain walls.

Although the transparent screen as a subdivision is not as popular as the "LED small-pitch screen", the future development space of the transparent screen is large, and the transparent LED display will develop in the following directions:

1. The spacing is smaller, the display screen is more delicate, and the video effect is more high-definition;

2. Interactive elements, the audience can interact with the transparent screen, and the advertising effect will be better. At the same time, 3D video elements, VR elements, etc. are introduced. Further explore the commercial value of transparent screens

3. More energy saving and environmental protection, the breakthrough of common cathode technology for transparent screen. Energy saving and environmental protection means lower broadcast costs and easier acceptance by merchants. At the same time, it is also in line with the concept of green energy saving and has potential advantages in the approval and advertising markets.
