A display device that allows you to see the content of the screen and the objects behind it through the screen. Simply put, it is a transparent screen. It does not completely block the light like a traditional screen, but uses a special optical design to present the display content and the background environment in front of your eyes. When many people see a transparent screen for the first time, they think it looks like a prop in a science fiction movie, but in fact it has gradually become popular in shopping mall windows, exhibition halls, and even car windshields.
What is the display principle of transparent screen?
The key to the "transparent" nature of a transparent screen lies in abandoning the backlight module behind the traditional LCD screen or adopting unique light guide technology. There are two mainstream transparent screen implementation methods on the market. One is based on OLED self-luminous technology. Since each pixel can emit light independently without the need for a backlight, when the pixels do not emit light, light can directly penetrate the screen.
Another type is the LCD transparent screen, which relies on edge-type LED light strips to guide light into the interior of the glass. It uses a special arrangement of liquid crystal molecules to control the light transmission, and can also allow most ambient light to pass through.
In actual use, you will notice that the transparency of the transparent screen is not 100%. Generally, it can reach about 70% to 85%. It is like a piece of colored glass. Although you can see the things behind, it will have a slight gray or blue color. In order to ensure that the picture can be seen clearly, the brightness and contrast of the transparent screen need to be specially adjusted. Otherwise, in a strong light environment, the picture will become very light, almost difficult to see clearly. Many high-end transparent screens also add anti-reflective coatings to solve this problem.
Is the display effect of the transparent screen really good?
This problem needs to be looked at on a scenario-by-scenario basis. In indoor light-controlled environments, such as glass showcases in shopping malls or museum showcases, the effect of transparent screens is amazing. You can play product introduction videos on the glass displaying jewelry at the same time. The images overlap with the real objects, which has a strong visual impact. However, if you move it outdoors to a place exposed to direct sunlight, the effect will be greatly reduced. The screen will appear whitish and the transparent part will become blurred due to light interference.
Another key element that plays an important role in the effect is the viewing angle. The viewing angle of a transparent screen is generally narrower than that of an ordinary screen. When viewed from the side, the brightness and color of the screen will be significantly reduced. And because the screen itself is transparent, the color of the background behind it will directly affect the picture performance. If there is a white wall behind it, the picture will look very light. If there is a dark background behind it, the picture will be clearer. Therefore, before installing a transparent screen, you must fully and comprehensively consider the related environmental conditions behind it, and you must not just find a place to install it rashly.
Therefore, before installing a transparent screen, you must fully consider the environmental conditions behind it, and do not just find a random place to install it. Because this factor will greatly affect the final effect of the transparent screen. For example, if the environment behind is messy and colorful, it may interfere with the original clarity and purity of the picture. Or, if the lighting conditions behind are poor, too bright or too dark, the brightness and color performance of the picture will be greatly reduced. Only by comprehensively and carefully considering the environment behind can we ensure that the transparent screen can achieve the ideal visual effect after installation and bring a high-quality visual experience to viewers.
For transparent screens, the most mature application scenarios at present are commercial displays and advertising windows. It is more similar to a decorative screen that can attract people's attention, and is not an object used to replace the TV or computer monitor in your home. If you just want to buy a novel gadget, the effect may not meet your expectations; however, if you are engaged in commercial display work and want to create a sense of technology and interactivity, then a transparent screen is definitely a good choice.
