T-OLED screens that are embedded in the windows of land transport give us the opportunity to touch the world of the future, when the border between the real and virtual worlds will become even more blurred, even today. Metro Media, in collaboration with Oktoglass, uses the technology of transparent OLED displays to open up new perspectives and set high standards for the development of future public transport.

Advantages of transparent displays in transport: a detailed look

Interactive window to the world of augmented reality: imagine that the window of your bus or train turns into a giant touch screen. You can not only view news, traffic schedules, or commercials, but also interact with them, leave comments, or make purchases. At the same time, without losing sight of the image outside the window.

Take personalization to the next level: each passenger can create their own unique visual experience. Your favorite movies, relaxing landscapes or even virtual tours of exotic countries-all this becomes available right during the trip.

Safety and Comfort: Transparent displays can display important safety information, such as approaching a stop or changes in the weather, such as warnings about thunderstorms, snowfall, or extreme heat. In addition, they can create a pleasant atmosphere, for example, imitating the starry sky or sea waves, which is especially important when traveling in the subway, where there are only kilometers of communication cables outside the window.

New business opportunities: advertisers get the opportunity to create more effective and memorable advertising campaigns. Imagine how the commercial smoothly flows from the virtual world to the real objects outside the window.

Efficient use of space: transparent displays can be used to display information about the route, schedule and other useful data, which allows you to free up additional space in the vehicle cabin, increasing the overall saturation of detailed information.

Contrast problem and its solution

The electrochromic filter is a real revolution in the field of transparent displays. It allows you to automatically adjust the transparency of the glass depending on the ambient light level. Thanks to this, the display image always remains clear and high-contrast, even in the most difficult lighting conditions. It is on such filters that Oktoglass specializes.

Example: imagine that you are traveling on a train on a sunny day. The sun's rays create glare on the display, and the image becomes faded, low-contrast, and black areas in the image completely disappear. The electrochromic filter instantly responds to changes in light conditions and darkens the glass, increasing the contrast of the image to a comfortable state, and black color returns in the content displayed on the screen.

Potential applications

Transparent displays have huge potential not only in the field of transport, but also in other areas:

• * Architecture: buildings with transparentfacades that can change their appearance depending on the time of day or event.
• * Retail trade: storefrontsthat turn into interactive platforms for displaying goods and services.
• * Museums and exhibitions: expositions that come to life thanks to augmented reality and interactive elements. And with the use of an electrochromic filter, it is possible to reduce the exposure time under bright light of particularly valuable antiques or art.

Additional aspects

• * Energy efficiency: an important aspect is the power consumption of transparent displays and electrochromic filters. Modern technologies make it possible to create energy-efficient solutions that do not burden the on-board networks of vehicles. The power consumption of a typical OLED display is 110 watts, and the electrochromic filter is even less than 1 watt. A special feature of the electrochromic filter is that it works as a "hot mirror", passing the visible spectrum of radiation, and completely reflects the thermal infrared. Thus, the need for air conditioning or heating is reduced, passengers inside the vehicle move in more comfortable conditions, and the OLED display does not experience excessive climatic load.
• * Interact with other devices: Transparent displays can be integrated with other devices, such as smartphones and tablets, to create an even more personalized user experience.
• * Social aspects: The ubiquitous use of transparentdisplays can affect our social interaction. It is important to find a balance between technology and human communication.

Challenges and prospects

Despite all the advantages, transparent display technology is still under development. One of the main challenges is the high cost of final products. However, as demand increases and technology advances, prices for transparent displays will gradually decline.
