Title:
OPTICAL SENSOR DEVICE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/040492
Kind Code:
A1
Abstract:
An optical sensor device and a display apparatus, the optical sensor device comprising: a base substrate (1); a detection circuit (2), which is located on the base substrate (1); a plurality of photosensitive devices (3), which are located on a side of the detection circuit (2) facing away from the base substrate (1); a plurality of light-condensing elements (4), which are located on a side of the photosensitive devices (3) facing away from the base substrate (1), the orthographic projection of one light-condensing element (4) on the base substrate (1) covering the orthographic projections of at least two photosensitive devices (3) on the base substrate (1); and a light constraint structure (5), which is located between the photosensitive devices (3) and the light-condensing elements (4), the light constraint structure (5) having a plurality of optical channels (51) in one-to-one correspondence with the photosensitive devices (3), each optical channel (51) being obliquely arranged, and two adjacent optical channels (51) being symmetrically arranged relative to the central axis of each light-condensing element (4). Each optical channel (51) is configured to allow incident light having an incident angle within the range of (φ-θ, φ+θ) to be emitted onto each photosensitive device (3), φ being the included angle between the central axis of the optical channel (51) and the central axis of the light-condensing element (4).
