I. Product Overview
LED flexible screens, also known as LED soft modules or LED soft screens, are a type of LED display product made from flexible materials. The screen is composed of a flexible substrate, LED light-emitting chips, drive circuits, and control chips. It features lightweight, ultra-thin, and transparent characteristics. The screen can be bent, folded, or even twisted according to specific needs, perfectly fitting various complex shapes for display purposes.
II. Features and Advantages
1. High Flexibility: The LED flexible screen is based on a flexible circuit board (FPC), allowing it to bend or fold at certain angles without damaging internal components. It is suitable for installation in non-flat locations such as columns, curved surfaces, and wave-shaped structures.
2. Ultra-thin and Lightweight Design: Using lightweight materials, the LED flexible screen has a compact structure, minimal thickness, and light weight, making it easy to transport, install, and maintain.
3. Excellent Display Quality: While maintaining flexibility, the LED flexible screen still provides high resolution and color saturation, delivering fine image quality that meets the demands of high-quality visual communication.
4. Seamless Splicing Technology: With special connection technology and modular design, seamless splicing is achieved, creating a complete and smooth large-scale display screen.
5. High Customizability: The LED flexible screen can be customized in shape and size according to project requirements, meeting individual and creative design needs.
6. Durability and Stability: Despite its flexibility, the LED flexible screen offers good waterproof, dustproof, and temperature-resistant performance, ensuring long service life and adaptability to complex environments.
III. Application Scenarios
1. Luxury Hotels: LED flexible screens can be used for hotel decoration, achieving functions such as advertisement displays, large clocks, and rate boards, helping hotels promote featured products and services.
2. Commercial Centers: In large shopping malls, LED flexible screens can solve the monotony of load-bearing beams while achieving commercial promotions, such as discounts and new product launches.
3. Entertainment Venues: LED flexible screens can be customized for various products based on the characteristics of the venue, such as bar screens, wave-shaped screens, and fan-shaped displays, creating colorful lighting effects and enhancing the visual experience.
4. Smart Technology: In smart homes, LED flexible screens can be used for lighting; in smart transportation, they can be used as traffic lights; in the medical field, they can be used as surgical lights, viewing lamps, and other medical device light sources.
IV. Product Quality Evaluation Standards
1. Surface Flatness: The surface flatness of the LED flexible screen requires extremely high precision, with errors controlled within 1mm to ensure that the displayed images are not distorted. Any localized bulges or depressions may cause dead angles in the viewing angle of the display. Achieving this standard is closely related to the manufacturer’s production process.
2. White Balance Performance: White balance is crucial for LED flexible screens. The ideal white balance should meet the ratio of red, blue, and green primary colors at 14:60:16 to present a pure white. Any deviation from this ratio may lead to white balance distortion, with common issues being a bluish or yellow-green tint. The quality of white balance is primarily controlled by the LED flexible screen’s control system, while the color reproduction of the LED chips also plays a significant role.
3. Color Block Issue: Color blocks refer to significant color differences between adjacent modules on the LED flexible screen. This phenomenon is usually caused by problems with the control system, insufficient gray levels, or low scanning frequency.
4. Brightness and Viewing Angle: The brightness of indoor LED displays should exceed 800 cd/㎡, semi-outdoor displays should exceed 1500 cd/㎡, and fully outdoor environments require 3500-5000 cd/㎡ to ensure clear visibility. The brightness of the LED display is directly related to the LED chips used, while the viewing angle size affects the number of viewers. Ideally, the larger the viewing angle, the better. The size of the viewing angle is primarily determined by the packaging method of the LED chips, and a balance between brightness and viewing angle must be found.
5. Mosaic and Dead Pixel Phenomenon: Mosaic refers to the small, constantly black or constantly bright squares on the LED flexible screen, usually caused by poor quality connectors. Dead pixels are individual points on the screen that are always on or off, and their quantity is mainly determined by the quality of the LED chips.
6. Color Reproduction: Color reproduction refers to the ability of the full-color LED flexible screen to replicate the original colors. Ensuring that the colors displayed by the LED flexible screen are highly consistent with the colors of the source content is key to maintaining the authenticity of the image.
V. Industry Development Trends
LED flexible screens show tremendous potential in both technology and market aspects. With the continuous advancement of flexible display technology, the resolution and color performance of LED flexible screens will continue to improve, production processes will become more mature, and production costs will gradually decrease. In terms of market application, LED flexible screens will find broader applications in indoor and outdoor advertising, stage performances, smart homes, and many other fields.
