In the field of modern display technology, transparent LED displays are receiving increasing attention due to their unique transparency characteristics and stylish visual effects. Among them, LED film screen and LED crystal film screen are two common transparent display solutions. So, what is the difference between them? This article will provide a detailed analysis of the differences between the two from multiple perspectives.
1、 Basic concepts
1. LED film screen
LED film screen is a type of ultra-thin display screen that embeds tiny LED light beads into a transparent flexible PCB board. Because it can be attached to transparent media such as glass like a film, it is called a "film screen". It combines transparency and display function, and is widely used in fields such as glass curtain walls and window displays.
2. LED film screen
LED crystal film screen is a highly transparent display screen formed by encapsulating LED chips on a transparent conductive film using nano optoelectronic materials. This screen has a crystal clear visual effect, hence it is called a "crystal film screen". It is mainly used in high-end venues such as museums, technology exhibition halls, etc.
2、 Production process
1. Manufacturing process of LED film screen
Flexible circuit board production: Using flexible and transparent PCB board as the substrate.
LED mounting: Using SMT technology to mount tiny LED beads onto a PCB board.
Protection treatment: Encapsulate and protect the circuit board and lamp beads to prevent oxidation and damage.
Connection method: Connect modules through FPC (flexible flat cable).
2. Manufacturing process of LED crystal film screen
Preparation of conductive film: Transparent nano conductive film is used as the substrate.
Chip packaging: The LED chip is directly packaged on a conductive film to form pixel points.
Overall packaging: Package the entire screen to ensure transparency and stability.
Bonding process: The crystal film screen is directly bonded to transparent media such as glass without the need for a frame.
3、 Performance comparison
1. Transparency
LED film screen: Due to the use of PCB board and circuit, the transparency is generally between 60% -85%.
LED crystal film screen: using nano conductive film technology, the transparency can reach over 90%, and the visual effect is better.
2. Thickness and weight
LED film screen: thickness between 1-3 millimeters, relatively heavy in weight.
LED film screen: with a thickness of less than 1 millimeter, it is lighter in weight and has less impact on the structure.
3. Brightness
LED film screen: High brightness, suitable for outdoor or strong light environments.
LED film screen: relatively low brightness, more suitable for indoor environments.
4. Installation method
LED film screen: requires professional installation brackets and fixing devices, and the installation process is relatively complex.
LED crystal film screen: It can be directly attached to the glass surface, easy to install, and does not require additional structure.
5. Maintenance costs
LED film screen: Due to its complex structure, maintenance costs are high.
LED crystal film screen: simple structure, low failure rate, and low maintenance cost.
4、 Application scenarios
1. Application of LED film screen
Shopping mall window display: used for product advertising and brand promotion.
Architectural glass curtain wall: as a media display for the exterior facade of a building.
Stage stage design: used for background display in large-scale concerts and press conferences.
2. Application of LED Crystal Film Screen
High end exhibition hall: used for technology display, art exhibition, etc.
Sightseeing elevator: Display information or advertisements on the elevator glass.
Interior decoration: used for decorating high-end places such as hotel lobbies and conference rooms.
5、 Advantages and disadvantages analysis
1. LED film screen
Advantage:
High brightness: suitable for various lighting environments.
Strong applicability: can be tailored according to needs, adapting to different sizes and shapes.
Mature technology: Mature production process and complete supply chain.
Disadvantages:
Low transparency: Lines and light beads have a certain impact on transparency.
Installation complexity: requires professional personnel and auxiliary equipment.
2. LED film screen
Advantage:
Ultra high transparency: does not affect the transparency of the glass.
Lightweight and convenient: It has little impact on the original structure and is easy to install.
Beautiful and fashionable: with excellent visual effects, it enhances the level of the venue.
Disadvantages:
Limited brightness: Not suitable for strong light environments.
High cost: high technical content, relatively expensive price.
6、 Technological development trends
1. Balance between Transparency and Brightness
The future technological development will strive to improve transparency while enhancing screen brightness to meet the application needs of more scenarios.
2. Flexibility and Customization
The flexibility and customizability of screens will be an important development direction, enabling them to adapt to more complex installation environments and design requirements.
3. Integration of interactive functions
Add interactive functions such as touch and sensing, so that the screen not only has a display function, but also interacts with users, improving the user experience.
7、 Choose Suggestions
Budget considerations: If the budget is limited and transparency requirements are not extremely strict, LED film screen is a more economical choice.
Application environment: In high-end places that require high transparency and lightweight installation, LED film screens are more suitable.
Brightness requirement: Choose LED screen with higher brightness for outdoor or strong light environments.
Installation convenience: If you require easy installation and minimal changes to the original structure, LED crystal film screen is a better choice.
