Problems solved by technology

In related technologies, the energy utilization rate of the TOF sensor is low. When the electronic device is equipped with the TOF sensor, in order to ensure that sufficient reflection signals are received, it is necessary to increase the power of the light emitting module or extend the working time of the light emitting module, thereby lead to higher power consumption of electronic equipment

Abstract

The invention discloses a light receiving module, a flight time device and electronic equipment. The light receiving module comprises a pixel array, a circuit array and a microlens array. The pixel array comprises a plurality of pixel units. The circuit array includes a plurality of circuit units. The plurality of pixel units and the plurality of circuit units are arranged at intervals. The pixel array and the circuit array are located on the same plane. The microlens array includes a plurality of microlenses. The microlens array covers the pixel array and the circuit array. The area of the pixel unit covered by each microlens is larger than the area of the corresponding circuit unit. External light can be converged to the pixel units through the microlenses to generate electric signals. According to the light receiving module, the flight time device and the electronic equipment, the area of the pixel unit covered by each microlens is larger than the area of the corresponding circuit unit, and more external light can be converged to the pixel units through the microlenses, so that the energy utilization rate of the flight time device is improved, and the power consumption of the electronic equipment is reduced.

Description

technical field [0001] The present application relates to the technical field of sensors, in particular to a light receiving module, a time-of-flight device and electronic equipment. Background technique [0002] Usually, the Time of Flight (TOF) sensor includes a light emitting module and a receiving module. , by calculating the time difference or phase difference between light emission and reflection, the distance of the object to be photographed is calculated to form depth information. In related technologies, the energy utilization rate of the TOF sensor is low. When the electronic device is equipped with the TOF sensor, in order to ensure that sufficient reflection signals are received, it is necessary to increase the power of the light emitting module or extend the working time of the light emitting module, thereby Lead to higher power consumption of electronic equipment. Contents of the invention [0003] Embodiments of the present application provide a light rece...
