Common transparent LED display and its advantages and disadvantages
Transparent LED display as a subdivision of the display industry, set light, thin, transparent advantages, has been rapidly developed in the past 5 years. The transparent LED transparent screen on the market can be divided into six categories: positive luminescence, side luminescence, film screen, film screen, photoelectric glass, grid screen:
These 6 products have both advantages and disadvantages. With the development of technology and the validation of the market, many of them have done well enough in many aspects. In addition, there has never been a perfect product, I hope you can correctly understand the characteristics of each product, use, according to their own needs to choose the right product, application in the right field.
A: positive light transparent LED display
Positive luminescence transparent screen using conventional SMD lamp beads mounted on the hollow PCB board, will drive IC centralized placement. This product is made of conventional components and conventional technology, so most LED transparent screen manufacturers have such products. Such products are mainly used in Windows, chain stores, stage rental, bars and other fixed size occasions without special customization.
Advantages:
Simple production process
Use traditional components
There is no dark line between the light bars
Disadvantages:
The hollow-out rate is low
The location of IC concentration is prone to color bias
Cutting is not flexible, not easy to customize
The second type: side luminous transparent LED display
The side luminous transparent screen is mounted on the PCB light strip by SMT process. This product is only a kind of application form of side light lamp beads, SMT process difficulty is higher than positive light products, so general manufacturers also have such products. The product is suitable for the glass curtain wall with variable size and special-shaped customization.
Side light transparent LED display beads display
Advantages:
Head-up hollow out rate is high
High brightness of products
Easy to customize
Disadvantages:
Different Angle of view and different hollowed-out
The light bar is prone to bright and dark lines, flower screen
Left and right Angle color bias, screen back light leakage
Three: LED film screen
Film screen is the use of lamp drive lamp beads, mounted on a certain hollow ultra-thin PCB board. It was protected with clear film and PC before and after. This kind of product is suitable for atrium fence, chain store, glass curtain wall and other occasions.
Film screen panel display
Advantages:
Easy installation
Product lightweight
High transparent rate
Disadvantages:
Different Angle of view, high failure rate
Highlight colour cast
No brand lamp beads optional
Four: LED soft film screen
The soft film screen is also called crystal film screen because it is transparent like crystal. Is the use of lamp drive lamp beads, mounted on a transparent conductive film. It is mainly used in indoor occasions such as atrium fence and glass partition.
LED soft film display
Advantages:
High permeability
Product lightweight
Strong sense of science and technology
Disadvantages:
Small visual Angle, high failure rate, color bias
The exposed line is easy to oxidize and has little adhesion
Patch adhesion does not meet the patch standard
Five: LED photoelectric glass
Photoelectric glass screen is a kind of product in which the lamp beads are pasted on the transparent conductive glass. These products are suitable for indoor glass partition, atrium fence and other occasions.
Photoelectric glass screen panel partial display
Advantages:
Hollow out rate is high
Strong sense of science and technology
Good flatness
Disadvantages:
It's not seamless, it's not curved
Poor adhesion of the line
Low brightness, not easy to maintain
Poor adhesion of the line: because of poor adhesion of the line, the lamp beads will be easy to fall after mounting, which does not meet the standard of the patch
Six: LED grid screen
Grid screen is a single PCBA lamp into the aluminum profile, and then the lamp surface glue a class of products. There are two forms of straight lamp beads and table lamp beads. Such products are generally used as outdoor products with large spacing, and the spacing is mostly concentrated between P16 and P100. Mainly suitable for outdoor building display, lighting.
LED grille screen box display
Advantages:
Conventional element equipment
High voltage transmission
Easy to customize
Disadvantages:
Large span flatness is difficult to ensure
How heavy the glue is
The input line at the control end is messy
