Over the years, we have often heard relevant news about flexible display technology and how it has changed the way we use mobile devices, such as folding, bending, or even bending at extreme angles. Although we are still unable to see super-flexible phones or wearable devices, some semi-flexible or curved screen mobile devices are already on the market, including LG G Flex and Samsung Galaxy Round.

Some time ago, we also saw a number of tests on the two surface phones Samsung and LG, including a variety of different bending and stress tests, and the results did not meet the expectations of most consumers. However, with the advancement of technology, OTFT organic film transistor technology may soon be integrated into flexible devices, and even more flexible and foldable devices of various types have emerged. Recently, the British Industrial Process Innovation Center (CPI) demonstrated its new backplane manufacturing technology for OTFT, which can bend the OTFT substrate to a radius of curvature of 1mm without any significant decrease in performance.

Although in the video above, we saw at least a few simple bends, and in fact more than 10,000 bends during the test show that the test primarily observes the smallest changes in voltage and current and is sufficient for significant attenuation. CPI said that this super bending radius can be optimized through multiple interfaces of the device stack to ensure a good adhesion experience in bending tests.

In fact, as early as 2010, Sony has announced the world’s first 4.1-inch OTFT-based full-color OLED screen. This screen is extremely flexible and can be easily wound on a cylinder with a radius of 4mm, even when wound. During the process, the OLED screen can also produce dynamic images, and the display effect is still not affected after rewinding 1000 times. At that time, Sony said that this type of display will be applied to thin, durable mobile devices in the future, and the specific time point was not disclosed.

In many concept videos, most of the mobile devices in the future can be folded or deformed. Even if many users do not expect to become reality immediately, it will eventually become possible with the development of technology.
