Judging from the current products on the market, the transparent LED display has a maximum permeability of 90%, and the minimum dot pitch is 2.6mm.
For a transparent LED display, has its permeability and dot pitch reached its limit? In fact, not yet, because the PCB board, the driver IC, and the lamp beads themselves are opaque. If the dot pitch is made smaller, it will inevitably lose a part of the permeability, and the high permeability is precisely the transparency, the biggest advantage of the TGC series glass LED display.
The price of improving the permeability is the expansion of the dot pitch, which affects the clarity and display effect of its picture, which becomes a dilemma.
The side-emitting LED lamp beads used in transparent LED displays on the market are not very versatile, with poor consistency and stability, resulting in high production costs and troublesome after-sales service.
At present, there are many customized products in the market, and the quantity is small, and mass production is more difficult. This is also an important reason for the high cost of transparent LED displays.
The so-called "true transparency" means that the transparent glass LED diplay must be truly integrated with the glass structure.
Standardization can reduce costs, and customization can make the transparent LED display and the building achieve a high degree of harmony.
When designing the advertisement on the transparent glass LED display, at present, 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 and this method can greatly reduce light pollution.
