Transparent screens, at first glance, sound like props in science fiction movies, but in fact, they have begun to enter our daily lives in recent years. It is essentially a piece of transparent glass that can display the picture. When it is turned off, it looks like an ordinary piece of glass, and when it is turned on, the picture seems to be suspended in the air. It does have a technological feel. However, before many people actually touch it, they will have such doubts in their hearts: Is this thing reliable? Can its display effect really be as transparent as shown in the promotional video?
Will the display effect of the transparent screen affect viewing?
This is the first thought that comes to everyone after seeing a transparent screen. In fact, what everyone is worried about is whether this thing is like some cheap projectors. It is difficult to clearly see the details of the screen display content when the light is sufficient during the day, and it will produce a strong and dazzling light effect when the light is dark at night.
The imaging principle of a transparent screen is different from that of an ordinary display screen because it emits light by itself and does not require reflection from the screen like projection. There are currently two mainstream transparent screen technologies, one is OLED transparent screen, and the other is LCD transparent screen. OLED has better transparency, purer black field, and richer colors, but it is also more expensive. The cost of transparent LCD screens is relatively low, but the light transmittance and contrast will be reduced.
In fact, in an environment with normal indoor light, the display content presented by the transparent screen is clear, especially when the background is dark or solid, the picture seems to be suspended in the air. However, if the background is too bright and cluttered, such as with the sun behind it or a bunch of brightly lit billboards, then the contrast of the picture will drop and it will look slightly "light". Therefore, the installation location is very important. It is best to choose a place where the background brightness can be controlled, such as the atrium of a shopping mall or behind the display cabinets of exhibition halls.
Where can transparent screens be used?
Many people believe that the transparent screen is just a gimmick and has no practical use other than it looks good. However, in fact, its specific application scenarios are much richer than you think.
In the retail industry, it was the first to try something new. In some high-end mobile phone stores and jewelry stores, you can see that transparent screens are installed on the window glass. During the day, it appears as a piece of transparent glass, through which customers can see the products displayed in the store; at night, or when information needs to be displayed, it transforms into a screen and then plays product promotional videos and price information. In this way, the window does not need to be pasted with posters, and the content can be changed at any time, and it also looks very high-end.
The transparent screens have outstanding advantages in exhibition display. Just like in a museum, the glass of the showcase displaying the exhibits is actually a transparent screen. Visitors can visually examine the actual objects here, and the screen will overlay the background of the cultural relics and the 3D restoration image. The information layering is very obvious. There is also a science and technology museum that uses transparent screens as interactive devices. Once people stand in front of it, the images and portraits are superimposed, and the effect is very futuristic.
It is also used in office and commercial spaces. For example, in conference rooms, transparent screens can act as smart glass and are usually transparent. They can display agendas and project screen materials during meetings, and can also be used as whiteboards. In hotel lobbies and corporate front desks, when transparent screens are installed, the sense of technology and class of the entire space will be significantly improved.
Of course, a transparent screen has its limitations. Its resolution is usually lower than an ordinary screen of the same size because some pixels are occupied by transparent areas. In addition, its brightness is not top-notch and is not suitable for outdoor environments with direct sunlight. However, in general, as long as you choose the right scene, a transparent screen is by no means a decoration, but a tool that can truly improve user experience and commercial value.
