Image capturing device under screen and electronic equipment
View Patent ↗The image capturing device under the screen and the electronic equipment including a nonopaque cover plate, a light source module, and a photosensor module are provided. The nonopaque cover plate, the light source module, and the photosensor module are sequentially arranged from top to bottom. The nonopaque cover plate is provided with nonopaque area, the light source module includes a plurality of light sources arranged in an array, the photosensor module comprises a plurality of discrete photosensors. The light emitted from each light source toward the nonopaque area is reflected by the nonopaque cover plate and received by one photosensor in the photosensor module. By the above-mentioned scheme, the biometric information on the nonopaque area that is outside the projection range of the photoelectric sensor can also be obtained by the photosensors, effectively increasing the imaging area of the photosensors, effectively reducing the area of the photosensors required to detect the same image information, preventing from occupying too much space under the screen, and saving hardware costs.
