Abstract

The invention discloses a photoelectric sensing device and electronic equipment. The photoelectric sensing device comprises a semiconductor substrate, wherein the semiconductor substrate comprises a first surface and a second surface opposite to the first surface; a plurality of light sensitive pixels are formed on the first surface of the semiconductor substrate; a plurality of through holes which pass through the semiconductor substrate toward the first surface are formed on the second surface of the semiconductor substrate; and the through holes correspond to the light sensitive pixels. Theelectronic equipment comprises the photoelectric sensing device.

Description

technical field [0001] The invention relates to the field of photoelectric sensing, in particular to a photoelectric sensing device and electronic equipment. Background technique [0002] At present, biometric information sensors, especially fingerprint recognition sensors, have gradually become standard components of electronic products such as mobile terminals. Since the optical fingerprint recognition sensor has a stronger penetration capability than the capacitive fingerprint recognition sensor, an optical fingerprint recognition module applied to a mobile terminal has been proposed. Such as figure 1 As shown, the optical fingerprint identification module includes an optical fingerprint sensor 400 and a light source 402 . Wherein, the optical fingerprint sensor 400 is disposed under the protective cover 401 of the mobile terminal. The light source 402 is disposed adjacent to one side of the optical fingerprint identification sensor 400 . When the user's finger F touc...
