Transparent screen product type and implementation principle
A transparent screen is a display screen that projects an image or video onto clear glass or plastic, allowing the user to look behind the screen. At present, there are mainly several types of transparent screen products on the market:
OLED Transparent screen: The OLED transparent screen is a transparent display composed of a frame and an OLED emitting layer. It can emit light directly without the use of backlight, and has the advantages of high contrast, high brightness, and wide color gamut. The principle of the OLED transparent screen is to use the characteristics of the OLED material to convert electricity into light energy. When an electric current passes through the OLED layer, the OLED material fluoresces to achieve the display effect. The advantages of transparent OLED screens are that they can be bent and crimped, and can achieve high-definition and transparent display effects.

LCD transparent screen: The LCD transparent screen is a kind of display screen that illuminates the LCD panel by the backlight, so that the scene behind can be seen through the LCD screen. The realization principle is to coat the LCD panel with liquid crystal material, through electricity to make the liquid crystal material changes, so as to control the transparency. The advantage of transparent LCD screen is strong color performance, and can achieve high definition, high transparency display effect.

LED transparent screen: LED transparent screen is a display screen that combines LED module and transparent material. Its realization principle is through the LED module light, the image is projected onto the transparent material, forming a transparent display effect. LED transparent screen has the advantages of high brightness, strong reliability, long life, suitable for outdoor large billboards and other application scenarios.
PDLC transparent screen: PDLC transparent screen is a transparent display screen composed of transparent conductive glass, PDLC liquid crystal film, ITO glass, substrate and other materials. The realization principle is to control the transparency of PDLC liquid crystal film by applying electric field, so as to realize the image display. The advantage of PDLC transparent screen is that it can become completely transparent when no display is needed, saving energy.
Collapsible transparent screen
The collapsible transparent screen can be folded into different forms, making it more flexible for embedding in different application scenarios, with better customizability and mobility. Its implementation principle is similar to that of the transparent screen that can be rolled, also using multiple layers of flexible organic materials, and can be folded in a variety of ways.
Double-sided transparent screen
The double-sided transparent screen has the feature of displaying images on both sides and can display different contents on both sides at the same time. The realization principle is to use transparent conductive materials on both sides, and add transparent dielectric layer in the middle, by controlling the electric field distribution in different areas, to achieve different display content on both sides.
3D transparent screen
The 3D transparent screen can display stereoscopic images and videos. It works by using multiple layers of transparent screens, each showing a different depth of content to create a three-dimensional effect. At the same time, the use of special glasses or naked eye 3D technology without wearing glasses can make the viewer experience more realistic.
In summary, the above is the introduction of several common transparent screen product types and their implementation principles. Due to the continuous progress of transparent screen technology, more types of transparent screen products may appear in the future. Different types of transparent screen products have different implementation principles, but they all have high transparency, good visual effects, diversified display content and other advantages, so they have a wide range of application prospects in business, science and technology, culture and other fields.
