What is a Bendable Display?
Bendable does not simply imply “curved”.
Although curved displays are interesting, they are not the same as bendable displays.
Conventional liquid crystal displays (LCD) include many layers such as a backlight, polarizer, thin-film-transistor layer, liquid crystals, color filter glass, and a polarizer. Although, LCDs are flat and rigid, but a couple of tech companies like Samsung have managed to make curved ones.
In past years, organic light emitting diode (OLED) displays have been extremely popular and provide many benefits such as better image quality and flexibility. OLED displays do not need a backlight source and thus can be slim such that they can be molded into curved displays.
Both, of the above types of displays, can be manufactured to bend. An Apple supplier “Japan Display Inc.” announced the development of a 5.5-inch flexible display by adopting plastic substrates instead of a conventionally used glass substrate that cannot bend. The curved displays which can bend can bring revolution in the tech industry and can take the engineering and material science to next level.
The major advantage of the bendable displays would be durability and it is assumed that plastic substrates would be used instead of glass. However, plastic is also not invincible.
Corning was working on Willow which is a bendable glass. Corning further plans to use this bendable glass in phone displays, TV displays, and even in wearable device displays. But again, Willow can break if bent too much.
Now, the main challenge for engineers is to develop materials that are unbreakable under the stress of flexibility and at the same time, that can show an image across the display with consistency.
Bendable Displays a Reality!
Recently, in CES 2021 TCL and LG unveiled rollable screens which turned these bendable displays into a reality. LG also revealed a bendable OLED screen with a curvature radius of up to 1,000R.

Future Possibilities?
In the future, it is possible to develop display devices that can be rolled over just like the sleeves of the shirt or can be folded like paper to fit into any space. But, for this, not just the display should be bendable, but the internal circuitry must be made bendable. Some tech companies like LG are already working on bendable circuits such as bendable battery packs. A bendable display could be used on the dashboards of your cars to digitize the dashboards. The displays can be used in any number of ways, and they can bring a revolution not just in the tech industry but also in other industries.
