LG wowed the world earlier this year at the CES design expo, showing off the first ever flexible OLED display. Now however, they have upped the ante again, debuting for a the first time a whole new kind of screen which in the years to come may revolutionize digital display technology.
In a press release yesterday they announced a new fully flexible large TV-size OLED display. Measuring in at a massive 18 inches, the screen can be flexed in multiple directions, and even rolled up into a 3 cm diameter cylinder, not much larger than a rolled-up newspaper.
In terms of resolution, the screen isn’t quite full HD, with just 1200x810px, however it is still a massive achievement given that previously fully flexible displays were limited to screen sizes of just a few inches, with much lower pixel densities. In addition, these pixels are all transparent when not lit up, allowing for a display which can be seen through like a window.
In order to build the revolutionary new display type, LG made use of new, high tech materials. Primary among these was the use of what they call “high molecular substance-based polyimide film” to comprise the backplate of the screen, replacing typical plastic construction. This film, as well as being highly flexible, also allowed the screen to cut down on thickness.
This new tech could have some interesting applications in a number of areas. It would allow mobile phones which have truly flexible displays, unlike previous “semi-flexible” models such as the G Flex or the Galaxy Round. The screens on these devices could also be made to be much more resistant to breakage due to them flexing rather than shattering.
Also it could create a much greater variety of tablets which more closely resemble the paper books and newspapers which they seek to emulate. Finally, the transparent nature of the screens would enable them to be used in areas where a user also needs to be able to see through them, such as in wearable glasses or in car windscreen heads-up displays.
