Transparent Screen Introduction
Transparent display is based on the conventional LED transparent screen to upgrade the innovative design, eliminating the rigid light bar or PCB board, making the screen body more thin and transparent, and with flexible and bendable qualities. Transparent display can be used as a conventional display, but also can be used in special display fields, such as creative shaped screen, column screen, spherical screen, curved screen, etc. It is widely used in glass curtain wall, shopping mall advertising, exhibition display, creative art landscape and other scenes.
Crystal film screen is one of the transparent screen subdivision products, used in the environment with glass, such as architectural glass curtain wall, glass window, glass fence, etc.. It has the characteristics of super high permeability and ultra thin and light. What is the difference between it and LED film screen, the following to understand.
Crystal film screen adopts LED lamp beads bare crystal ball implantation technology, the lamp board adopts transparent crystal film film film, the surface etching transparent mesh circuit, vacuum sealing glue process after the surface paste components, the product is light, transparent and thin, can be bent and cut as the main advantage; can be directly attached to the glass curtain wall, without damaging the original structure of the building; when not playing the screen invisible, does not affect the indoor lighting, viewing from a distance, can not see the screen installation traces. Crystal film screen light transmission rate of up to 95%, can present a bright and vivid image effect, so that the product image is more bright, super color for the user to create an excellent visual experience
Is LED crystal film screen the same as LED laminated screen?
In fact, they are not the same products. Although LED film screen, LED crystal film screen are very flexible, bendable, both can be attached to the glass, extremely easy to install. Both are very light in weight, but they differ as follows.
1.Production process manufacturing
LED crystal film screen through the bare crystal implant ball technology, the lamp board using transparent crystal film film film, the surface etched transparent mesh circuit, the surface paste components after the vacuum sealing glue process.
LED film screen through a specific bare chip, the components are solidly mounted on a highly transparent PCB board, through a unique cover glue process, so that the display module is integrated into a lenticular substrate
2. Permeability
LED crystal film screen pass-through is higher, because LED film screen structure is simpler, no PCB board, using full transparent film film, so the pass-through is higher.
3. Weight
The weight of LED film screen is extremely light, about 1.3kg/m2, LED film screen 2~4kg/m2
Process advantages of crystal film screen
Since the IC pad of CSP package is only 150um*150um, there are 13 solder pins on one driver chip, so the requirements for mounting and soldering are very high, and the requirements for mass production are met by advanced clean workshop with specially selected advanced equipment and mature process requirements and experience.
Due to the small and many pads, the printing requirements are very high, and the printing quality cannot be discerned by the naked eye and ordinary machines, which can be well solved by high precision testing machines.
The role of packaging
The overall performance of the encapsulated and protected LED transparent screen can be significantly improved, such as
Enhance the protection effect on LED beads: the optical material completely wraps the LED beads and the welding place to prevent the beads from falling off.
Enhancing the display: no air layer between the LED beads and the protective panel/glass, which reduces light loss, enhances brightness and reduces power.
Enhance the protection of circuit boards and metal lines: optical materials completely cover the circuit boards and metal wires to prevent short circuits in the lines caused by wire damage and oxidation.
Enhance the performance of dustproof, waterproof, moisture-proof and anti-collision: improve the overall adaptability and reliability of the LED screen and extend its service life.
In addition, the encapsulated and protected LED transparent screen has the following characteristics.
Light and thin, the thickness of the LED transparent screen after encapsulation and protection is 1.5-3mm, and the weight per unit area is ≤ 2Kg/m2.
High transmittance, flexible optical encapsulation material will not change the transmittance of the original LED flexible film screen.
Soft, bendable, cuttable, adaptable to curved structures and suitable for curved displays.
Easy installation, repair and maintenance, targeted replacement of dead lights, without the need to discard the entire screen.
Good weather resistance, products can withstand high/low temperatures, UV rays, outdoor products can withstand water showers and salt spray.
The overall cost is lower compared to gouge lamination.
