Interactive Display Techs at Touch Taiwan 2019
ITRI showcased several interactive display innovations at Touch Taiwan 2019.
Imagine that a shop window is a touch screen on which you can click for information about the products displayed behind, or that a transparent display can map needed surgical images onto observed organs to help surgeons perform operations more precisely. Now these are no longer fantasies. Take a glimpse of the tech innovations developed by ITRI and its showcase at Touch Taiwan 2019, and you will know how technologies turn imagination into reality!
Dual-User Interactive Window with Transparent AMOLED Display System
The dual-user interactive window adopts flexible transparent AMOLED display technology while integrating eye tracking with directive object recognition, touch function, staggered behavior identification and information fusion technologies. Its AMOLED display achieves the world’s highest transparency (70%), and the system can serve two viewers simultaneously, allowing an operating height range of 170 +/- 15 cm at a distance of 45 cm. The information fusion accuracy can reach within 5 mm, and the process time is less than 1000 ms. The smart window can be used in malls, exhibition centers, or museums, where visitors can click the display and get required product/exhibit information. It can also be used in transportation to provide needed traffic information for drivers and passengers.
Risk-Reduced Surgical Interactive Transparent Module
ITRI combines high-transparency AMOLED panels with virtual-physical technology to develop an interactive transparent display system for surgical assistance. AI object detection and eye tracking technologies are used to compute the user’s observation vector and the object’s observed surface. Then the system automatically selects the corresponding surgical assistance image information for projection. Consequently, preoperative or intraoperative images such as Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) information will be mapped to the objects on the transparent display. This system provides accurate real-time guidance for surgeons and is ideal for use in medical tutorials and smart image-guided surgery.
Low Retardation and Colorless Polyimide Film
Common smartphone screens have poor visibility in sunlight. The Low-Retardation Colorless Polyimide (PI) Film developed by ITRI, however, could make screens more readable in bright daylight. The film has a molecular structure design that modifies the polarization state of the transmitted light, which can effectively eliminate the coloration caused by birefringence (mura) and reduce display interference. This technology can be used in the polarizer protective film of liquid crystal displays and can work with alignment film. Compared to conventional PI film, ITRI’s solution has lower retardation and higher heat resistance, and moreover, can be integrated more easily with optical mechanisms and production processes to achieve a thin and light design.
The above are some examples that illustrate the possibilities that advanced display technologies can create. As ITRI’s Vice President and General Director of Electronic and Optoelectronic System Research Laboratories Dr. Chih-I Wu suggests, display is a perfect human-machine interface capable of integrating various intelligent systems, enabling 5G, IOT, and AI applications in retail, medical care, mobility and entertainment, as well as offering users interactive experience in smart living.
