Title:
PHOTO-SENSING DETECTION APPARATUS, DISPLAY APPARATUS, METHOD OF FINGERPRINT DETECTION, AND METHOD OF OPERATING DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/051276
Kind Code:
A1
Abstract:
A photo-sensing detection apparatus includes a counter substrate (2); an array substrate (1) facing the counter substrate (2); and a fingerprint sensing driver (3). The array substrate (1) includes a plurality of light sources(10) configured to emit light toward the counter substrate (2), at least a portion of the light being totally reflected by a surface (Sc) of the counter substrate (2) away from the array substrate (1); and a photosensor (20) configured to detect the at least the portion of the light being totally reflected by the surface (Sc) of the counter substrate (2) away from the array substrate (1). The photo-sensing detection apparatus is configured to be operated in a time-division mode including a plurality of time-sequential photo-sensing modes. The fingerprint sensing driver (3) is configured to detect a fingerprint information by integrating signals detected in the plurality of time-sequential photo-sensing modes.
