Development of Hover Sensor Technology for Highly Precise Non-Contact Input

Japan Display Inc. ("JDI") today announced that JDI has developed an external glass-based hover sensor that makes it possible to detect fingers with high precision up to about 5 cm from the transparent sensor surface.

JDI has moved forward with the development of hover sensor technology that makes non-contact input possible. This new technology is ideal for input devices used in medical, industrial, and public facilities applications such as automatic check-in machines, automatic ticket dispensers, vending machines, ATMs, and elevators. Throughout the world, there is a growing need for non-contact input devices in order to prevent the spread of viruses, including the novel coronavirus. Additionally, strict hygiene at medical facilities and food processing plants can be achieved and will prevent dirt on surfaces due to touch operation.

With this technology, we combine our algorithm and sensor boasting proprietary structure from the display-integrated in-cell touch sensor Pixel Eyes, based on low temperature polycrystalline silicon technology. This provides high transparency and makes it possible to detect fingers up to 5 cm from the sensor. Therefore, operations similar to traditional touch panel input can be used even if the panel is not touched and it can be applied to gesture operations based on movement of the finger, palm, or combination of both. The sensor also identifies false touches while monitoring it's changing ambient surroundings. All these features are incorporated into a minimized mechanical design that does not require a larger surrounding area.

JDI is also moving forward with the development of an in-cell hover sensor with an integrated display that has a non-contact input function. This provides thinner and lighter weight modules.

Samples will be available from Feb. 2021.

JDI will contribute to the creation of a hygienic society through the development of highly precise hover sensors that utilize non-touch sensing technology.
