Trinamix, Visionox, and STMicroelectronics have announced a joint solution for under-display facial recognition.
At its core is Trinamix’s “Face Authentication” technology, the module for which can be integrated into a device under Visionox’s semi-transparent OLED display. STMicroelectronics has provided a global-shutter CMOS sensor with a near-infrared capability.
A global-shutter CMOS sensor is a type of digital image sensor found in cameras and imaging devices, characterized by its ability to capture the entire image frame simultaneously. Unlike rolling-shutter sensors, which capture the image by scanning across the frame line by line, global-shutter sensors expose all pixels at the same time. This eliminates distortion effects in fast-moving scenes, such as the skewing or wobble that can occur with rolling shutters.
“Its class-leading pixel and advanced performances make our global-shutter image sensor a perfect match for use in Trinamix’ secure Face Authentication systems,” asserted David Maucotel, Head of the Personal Electronics, Industrial and Mass-Market Product Business Line at ST’s Imaging sub-Group. “It is ideal for creating ultra-compact modules and their easy integration into smartphones.”
A representative of Visionox’s Technical Management team, meanwhile, emphasized the firm’s unique position to provide its technology “quickly, cost-effectively, and reliably in large quantities”.
Visionox is indeed recognized as a significant player in the OLED industry, particularly in the domain of small to medium-sized OLED displays. Based in China, it has made notable strides in supplying OLED panels for various applications, including smartphones, wearables, and other consumer electronics. While it may not be as large or as well-known as some of the industry giants like Samsung Display or LG Display, Visionox’s contributions and advancements in OLED technology, including innovations in flexible and foldable displays, position it as an important supplier in the global OLED market.
Trinamix, for its part, is emphasizing the joint under-display face scanning solution’s utility in smartphones, and will be demonstrating it alongside its partners at this year’s Mobile World Congress event in Barcelona, which is slated to run from Feb. 26 to 29.
