Document Type and Number:
WIPO Patent Application WO/2020/243928
Kind Code:
A1
Abstract:
An optical image acquisition unit (10), an optical image acquisition system, a display screen, and electronic equipment. The optical image acquisition unit (10) comprises: a photoelectric sensing unit (201) provided on a thin film transistor (TFT) layer (200) of a display screen; an optical convergence device (401) provided above the TFT layer (200); a diaphragm (301) provided between the TFT layer (200) and the optical convergence device (401), wherein the diaphragm (301) is provided with a window (303). The optical convergence device (401) is used for transmitting an optical signal reflected by a target object above the display screen to the window (303), and the optical signal is transmitted to the photoelectric sensing unit (201) through the window (303). This solution can improve the optical image acquisition performance.
