Quick takeaway
There are mainly 9 different kinds of transparent LED screens, From their design, It can be categorized into:
1:Front lighting transparent LED screen,
2:Side lighting transparent LED screen,
3:Front lighting Side PCB transparent LED screen,
4:Adhesive film transparent LED screen
5: Thin flexible transparent LED screen film,
6: Glass film transparent LED screen,
7: Outdoor transparent LED screen,
8:LED stripe transparent LED screen,
9: Holographic transparent LED screen.
You can see the details below:
Front lighting transparent led screen is the basic type of the transparent led screen, It uses TOP type SMD lamp soldering on hollow PCB board with the IC on the back of the PCB board. The hollow design of the PCB make light pass through screen possible.
Pros:
1.1: It is easy to design, and produce
1.2: It use tradition led lamps and IC which is easy to get
1.3: It has a wide pixel pitch selection from pixel pitch 2.6mm to 15.6mm
1.4: It does not have obvious brighter or darker line in the screen
Cons:
1.1: The transparent rate is not good
1.2: IC are focus on the side of the screen, which make that area easy to have color shift due to heat raise
1.3: Size is not easy to customize
Side lighting transparent LED screen
Side lighting transparent led screen is use side lighting led lamp soldering on the side of the pcb board. As to reach high viewing angle, the led lamp need to be at the edge of the pcb board, which makes the SMT process harder than Front light solution.
Pros:
2.1 It has a high transparent rate when view horizontally
2.2:It can give a high brightness
2.3: It is easy to customize into different length
Cons:
2.1: It has different transparent rate between looking virtically and horizontally
2.2: It is eaiser to have brighter or darker line, random dots in screen
2.3: The color temperature is different between view from left and right
2.4: The back of the screen would also have lights
2.5: Difficult to produce
Front lighting Side PCB transparent LED screen
Front lighting lamp soldering on Side PCB transparent led screen is using normal front lighting SMD lamp, but instead of soldering on the PCB board’s surface, the lamp is soldering on the side of the PCB board. This needs the PCB to have special treatment, and also very hard to produce.
Pros:
3.1: It has a high transparent rate when view horizontally
3.2: It uses traditional led lamp and IC
3.3: Easy to customized different length
Cons:
3.1: Hard to produce, need special designed PCB board
3.2: It is eaiser to have brighter or darker line, random dots in screen
3.3: The soldering treatment is not strong, hence easy to lost lamp
Adhesive film transparent LED screen
Adhesive film transparent led screen (IC+lamp combo) uses special led lamp with IC built-in, As no IC needed, hence the PCB board can be more small ( which means more hollow space). After coating the PCB board with transparent film and pc, the screen have a very good transparent rate.
Pros:
4.1: Higher transparent rate
4.2: Lightweight
4.3: Easy to install
Cons:
4.1: The viewing angle is not consistent
4.2: It has color shift
4.3: It need special led lamp and also expensive
Thin flexible transparent LED screen film
Thin film transparent led screen is an upgrade of the adhesive file transparent led screen, It also have led lamp with built-in IC, but unlike the adhesive file transparent led screen that still use PCB board, Thin file transparent led screen uses conduct transparent materials on which the lamp is connected on.
Pros:
5.1: High transparent rate
5.2: lightweight
5.3: Easy to install
5.4: Advanced appearance
Cons:
5.1: Viewing angle is small
5.2: Color shift
5.3: The exposed wire is easy to get oxidation
5.4: The soldering process is difficult
Glass film transparent LED screen
Glass Transparent led screen uses led lamp which has built-in IC soldering on conductive glass, then cover the led lamp with another glass on top.
Pros:
6.1: High transparent rate
6.2: Waterproof can be used outdoor
6.3: Flatness
Cons:
6.1: Need design the glass from project to project
6.2: Hard to maintanence, can not bend
6.3: Can not make smaller pixel pitch
Outdoor transparent LED screen
Outdoor transparent led screen normally refer to the front lamp lighting transparent led screen, after special treatment like injection of glue to fill the space of the lamp and IC. So that it can be waterproof, sunlight proof and dust proof.
Pros:
7.1: Use tranditional lamps and IC
7.2: Waterproof and wind proof
7.3: Die casting cabinet makes the splicing easier
Cons:
7.1: smaller transparent rate
7.2: IC area have a high temperature as outdoor led screen have a high brightness needs
7.3: Can not customized cabinet
LED stripe transparent LED screen
Led Stripe transparent led screen (also can be called Grille Transparent led display) is normally used in big pixel pitch applications, it uses traditional SMD led lamp of DIP led lamp, which soldering on a stripe shape PCB. Then put the stripe PCB into Aluminium profile, and then fill the profile with glue to make it water proof
Pros:
8.1: Traditional lamps and IC
8.2: Easy to customized different size and pixel pitch
8.3: Easy to install
Cons:
8.1: It is hard to maintain flatness
8.2: Heavier
8.3: Need many wires to control the stripe
Holographic transparent LED screen
Led Stripe transparent led screen (also can be called Grille Transparent led display) is normally used in big pixel pitch applications, it uses traditional SMD led lamp of DIP led lamp, which soldering on a stripe shape PCB. Then put the stripe PCB into Aluminium profile, and then fill the profile with glue to make it water proof
Pros:
9.1: High Transparency rate, Currently the best transparency rate with good visual effect
9.2: Easy to customize different size, high brightness
9.3: Easy to install
Cons:
9.1: Screen size is limited, can not make too big
9.2: Difficult to repair
9.3: color shifting of the image
