Description

Technical Field

[0001] The invention discloses an LED transparent screen, in particular a transparent screen based on ultra-high light transmittance LED display manufacturing technology, belonging to the technical field of large-scale display equipment. Background Art

[0002] LED transparent screen is based on the traditional LED display screen, with improved patch manufacturing technology, lamp bead packaging and control system, and added hollow design structure. The LED power supply provides power, the control system conveys instructions, the driver IC provides display programs, the LED lamp beads display information, and the gaps between the parallel light strips are used to form a transparent effect.

[0003] LED transparent screens are widely used in commercial advertising, cultural entertainment, exhibitions, transportation hubs, and architectural decoration due to their high transparency, special-shaped design, high-definition display, easy maintenance, light weight and convenience, energy saving and high efficiency.

[0004] The transparent screens in the prior art are all realized by setting LED lamp beads or wafers on the substrate to realize the display, and setting the driving circuit on the substrate. In order to achieve the effect of the transparent screen, openings are usually set in the non-circuit area on the substrate so that the light behind the display screen can pass through the openings to achieve the effect of the transparent screen. When the substrate is opened, it is necessary to comprehensively consider the mechanical strength and the aperture ratio of the substrate. The aperture ratio directly affects the light transmission effect. The higher the aperture ratio, the better the light transmission effect, and the lower the aperture ratio, the worse the light transmission effect. If the aperture ratio is simply increased to increase the light transmission effect, it will affect the mechanical strength of the entire transparent screen, making it easy to be damaged during production, transportation, installation, and use. Therefore, taking comprehensive considerations, most of the current transparent screens use round holes or "8"-shaped hole structures, but there are still problems such as relatively low aperture ratios and unsatisfactory light transmission effects.

[0005] Currently, transparent screens are usually made in standard sizes. When a large screen is needed, multiple screens are spliced ​​together. The lamp beads on the screens all use RGB three-color lamp beads. When multiple screens are spliced ​​together, color inconsistencies are likely to occur at the seams of two relatively large screens. Summary of the invention

[0006] In response to the above-mentioned problems that the opening rate of transparent screens in the prior art is relatively low and the light transmission effect is not ideal, the present invention provides a transparent screen based on ultra-high light transmittance LED display production technology, which adopts an opening method that combines circular light transmission holes and waist-shaped light transmission holes.

[0046] The display screen in the present invention mainly includes a substrate 1, a display unit 2, a light board 5, a power box upper cover 9, a power box lower cover 8 and a power board 10. The display unit 2 is arranged on the substrate 1, and the light board 5 (used to connect with the driver) is connected to the substrate 1. In this embodiment, the light board 5 and the substrate 1 can be arranged integrally or separately. The power box upper cover 9 and the power box lower cover 8 are fixedly installed together to form a power box.

The three lamp beads or three chips on the RGB three-color LED lamp beads or RGB three-color LED chips are usually arranged in a "one" shape or a "pin" shape. The transparent screen module can be processed into type A module and type B module respectively. The arrangement direction of the RGB three-color LED lamp beads or RGB three-color LED chips on the type A module is opposite to that on the type B module. Taking the arrangement of three lamp beads in a "one" shape as an example, when the three lamp beads in the type A module are welded, the method is "R, G, B", then when the three lamp beads in the type B module are welded, the method should be "B, G, R". Since the type A module and the type B module are arranged oppositely during assembly, that is, the type B module is rotated 180° relative to the type A module. After the three lamp beads "B, G, R" in the type B module are rotated 180°, there is no "R, G, B", and it can just follow the arrangement method of the type A module, and no display abnormality will be caused at the joint.

[0051] The present invention adopts an opening method combining circular light-transmitting holes and waist-shaped light-transmitting holes. On the basis of meeting the mechanical strength, it can achieve the maximum opening rate to make the light-transmitting effect better.
