OLED technology has allowed us to go beyond the typical LED or LCD, as we have already been able to see flexible screens that were not possible before. But not only has that been achieved, but years ago LG already showed a prototype of flexible and transparent OLED displaywhich is already used in subways and trains of China Y Japan and now the company will use it in the means of transport of Europe Y North America.
When it comes to picking up the subway or trainmost of us are aware of their mobile, writing by WhatsApp or listening music. And it is that, these trips, especially if they are from long distancethey turn out very bored and we depend on external factors to have fun along the way. Under this premise, LG implemented its transparent OLED screens in the subways and trains of the Asian country a couple of years ago, although in this case they only showed information about stops and maps. Now, this technology reaches rail transport in Europe and North America, where it could be put to other different uses.
LG shows its transparent OLED screens for trains in Germany
LG has chosen the InnoTrans transport fair, which is held in Berlin, Germany, to be able to show its latest technology in transparent OLED panels. However, despite their name, they are not completely transparent at all times, but rather change depending on usage and content. For example, if they are turned off they do exhibit this aforementioned transparency, but when playing content they will vary between this and an almost opaque state.
In addition, this will depend on the content displayed, because as we see a map with stops of subway or train is shown almost transparent. On the other hand, if it is used to display advertising, the display would change completely. And it is precisely these two sectors, the information on stops and travel time, together with advertising, where we hope they will be destined. However, LG said in its official statement that they would be used to show newsnearby facilities and tourist attractions.
These transparent LG OLED screens use smart glass SPD (suspended particle device), which is tempered glass with GUI (insulated glass unit), which gives you great resistance to shocks and impacts. In addition to this, LG will show its “Show Windows“, a window of 2 x 2 m² with 4 x 55-inch transparent OLED panelsto create interactive display panels.
In China and Japan they already use this technology since 2020
Although it may seem like a technology of the future, this type of transparent OLED screens have been in use for a few years now. Specifically, in the Chinese and Japanese trains and subways. As we can see in the video, in this example you can see a transparent panel of these showing the typical route information, including the stops. While doing this, that much-mentioned transparency that they will offer is observed, being able to see the outside without problems.
Soon we should have this technology in Europe and if LG keeps its word that it will not be limited to only information on stops and advertising, it could be interesting. Although it must be taken into account that since currently the vast majority of people are already entertaining themselves with their mobile phones on these journeys, hard to find a use that justifies the price to pay to implement them.
