SCREEN ASSEMBLY NODE AND ELECTRONIC DEVICE Russian patent published in 2022 - IPC G06V40/13 

FIELD: electronics.

SUBSTANCE: invention relates to a screen assembly node and an electronic device. The screen assembly node contains a display panel and a recognition panel located on a non-radiating side of the display panel. The display panel contains a set of recognition areas. A non-recognition area is formed between two adjacent and spaced recognition areas. The recognition panel contains a set of image sensors. Photosensitive surfaces of the set of image sensors are made with the possibility of capture with unequivocal correspondence of user’s fingerprint images located in the set of recognition areas. The ratio of the total area of all recognition areas to the total area of all non-recognition areas in a fingerprint coverage area is more than or equal to 1:5.

EFFECT: reduction in the total area of photosensitive surfaces of a set of image sensors, when satisfying a requirement for the minimum capture area necessary during recognition of a fingerprint.
