In the LED display market, there is a very special LED display product, which is the transparent LED display. Unlike other LED displays, this product has a certain degree of permeability, so it can display media information without affecting the display of the items behind it.
At present, although transparent LED displays are widely used in various occasions, there are still some problems that we need to solve. Let’s take a look.
(1) Dilemma choice between permeability and dot pitch
Judging from several products currently on the market, the highest transparency rate of the transparent screen has reached 85%, and the minimum dot pitch is 3mm. For a transparent screen, does its transmittance and dot pitch have reached the limit? In fact, it is not, because the PCB board, driver IC, and lamp beads themselves are opaque.
If the dot pitch is changed Smaller, it will inevitably come at the cost of losing a part of the transparency, and the high transparency is exactly the biggest advantage of the transparent screen; and the price of increasing the transparency is the expansion of the dot pitch, which affects the clarity of its picture And display effect. Therefore, this is a dilemma.
(2) Questions about after-sales service, product maintenance convenience and product reliability
First of all, the side-emitting LED lamp beads used in transparent LED displays on the market have poor versatility, poor consistency and stability, resulting in high production costs and troublesome after-sales services. Secondly, there are more customized products on the market, and the quantity is small, and mass production is more difficult. This is also an important reason for the higher cost of LED transparent screens.
(3) How to achieve “true transparency”
The so-called “true transparency” means that the transparent screen must be truly integrated with the glass structure.
(4) Issues of standardization and customization
Standardization can reduce costs, and customization can make the transparent screen and the building achieve a high degree of harmony.
(5) The problem of light transmission on the back of the transparent screen
To play advertisements on this kind of screen, when designing the content of the advertisement, the unnecessary background color should be removed and replaced with black. Only the content that needs to be expressed is displayed. The black part does not emit light during playback, which is a transparent effect. , This playback method can greatly reduce light pollution.
Transparent LED display market application potential
The new transparent LED display has opened up a new application field and has a broad market prospect. It is especially suitable for the field of “architectural media”, catered to the needs of an emerging market, and successfully created a high-quality outdoor media resource.
According to statistics, the total area of modern glass curtain walls in China has exceeded 70 million square meters, mainly concentrated in urban areas. Such a huge stock of glass curtain walls is a huge potential market for outdoor media advertising. The advertising value of this market is not yet Being fully developed, the glass curtain wall is a new blue ocean field in the case of urban outdoor advertising resources being depleted day by day.
The scope of this field is very wide, such as urban landmark buildings, municipal buildings, airports, automobile 4S shops, hotels, banks, chain stores and other glass curtain wall buildings with advertising commercial value.
