Foldable, rollable, and wearable have been the trends in the display industry in recent years. E Ink, a global e-paper leader, has combined these features and developed a new display in cooperation with AUO-organic Thin Film Transistor (Organic Thin Film Transistor, OTFT) is an EPD display driving the backplane, suitable for wearable devices and smart clothing.

OTFT replaces inorganic silicon semiconductor materials in traditional components with organic semiconductor materials. Low-temperature processes can be used to reduce manufacturing costs. Large-area backplanes can be made. There is also an opportunity to complete backplane production with printing technology.

The OTFT backplane has the advantages of softness, flexibility, and high impact resistance, making it suitable for development and introduction into various flexible display products. In addition to soft and wearable applications, it is also suitable for the development of handwritten electronic paper notebooks, or for logistics electronic paper roll labels.

The e-paper film has soft material characteristics, combined with the impact-resistant OTFT backplane, can improve the durability of flexible e-paper, which is conducive to the expansion of the development of different terminal soft products, such as foldable and curlable (Rollable), wearable (Wearable) and other product applications.

OTFT materials have made great progress in the past few years. Combining OTFT as a flexible electronic paper module backplane will help reduce the manufacturing cost of flexible electronic paper displays and achieve mass production goals.

As electronic paper materials continue to improve, such as three-color electronic paper materials and advanced color electronic paper ACeP (Advanced Color ePaper) display technology, color electronic paper technology combined with OTFT technology will become a display solution suitable for wearable devices.
