LED transparent screens are among the most widely used display technologies. In the market, they are subdivided into various types to meet different needs. Common sub-products include LED film screens, LED grid screens, LED soft film screens, LED optoelectronic glass, front-emitting LED transparent screens, and side-emitting LED transparent screens. Next, we will introduce the characteristics and applications of each type of screen.
LED film screens are mounted on a PCB board using either integrated or separate LED driver mounting methods, protected between a transparent film and the PC. They are suitable for atrium fences, large brand chain stores, and glass curtain walls. Their advantages include convenient installation and lightweight design, but viewing angles are difficult to standardize, technical stability is limited, and color distortion is common under high brightness.
LED grid screens involve placing single OCBA LED strips into aluminum profiles and applying adhesive to form through-hole or surface-mount LEDs. They are mainly used for outdoor large-pitch products, such as building advertising and lighting projects. Their advantages include the use of conventional components, high stability, support for high-voltage transmission, and flexible customization. However, flatness is difficult to guarantee with large spans, the material is heavy after potting, and control lines are messy.
LED flexible film screens, using integrated lamps and drivers mounted on transparent conductive films, are suitable for indoor glass partitions, standing out for their high transparency, thinness, and technological feel. Disadvantages include limited viewing angles, a relatively high failure rate, easy oxidation of wiring, poor adhesion, and the technology is currently immature.
LED optoelectronic glass, using integrated lamps and drivers mounted on transparent conductive glass, is suitable for indoor glass partitions and atrium railings. Advantages include higher transparency, a strong technological feel, and good overall flatness. However, the product is not flexible, cannot be seamlessly spliced, has poor wiring adhesion, low display brightness, and is difficult to maintain.
Front-emitting LED transparent screens use SMD lamps mounted on a cutout PCB board with a centralized driver IC. They have a wide range of applications, such as glass windows, stage performances, large chain stores, and bars. Advantages include simple manufacturing processes, use of conventional components, high product stability, and no dark lines between the light strips. The disadvantages are limited cutout space, color distortion at IC concentration points, inflexible cutting, and potential customization difficulties.
Side-emitting LED transparent screens, where side-emitting LEDs are mounted on PCB LED strips using SMT technology, are suitable for glass curtain walls and custom-made irregularly shaped products. Advantages include more cutout space, better transparency, higher display brightness, and significant customization advantages. Disadvantages include significant differences in vertical viewing angles, susceptibility to dark lines and screen distortion, color distortion at horizontal viewing angles, and potential light leakage at the rear of the screen.
