AI Technical Summary

Technical Problem

Existing optical sensor driving devices cannot fully unleash the power of optical transmitters, limiting their performance, especially in laser sensors where the detection distance is short and they cannot meet more complex modulation methods and transmission protocols.

Method used

An electrical interface is led out from the optical sensor to the outside of the packaged base, so that the external high-power driving device can be connected to the optical emission component. Combined with the internal driving device, multi-mode driving can be realized, which is compatible with new transmission protocols and improves optical emission performance.

Benefits of technology

By connecting an external high-power drive device, the optical sensor can achieve ultra-long-distance laser detection and complex infrared modulation communication, satisfying more modulation methods and reducing structural design complexity and cost.

Abstract

This application provides an optical sensor, sensor assembly, and electronic device, belonging to the field of sensor technology. The optical emitting assembly is disposed within the encapsulation cavity of a packaged substrate. An electrical interface is provided on the outer surface of the packaged substrate, and the electrical interface is electrically connected to the optical emitting assembly. The exposed electrical interface can be externally connected to a first driving device located outside the packaged cavity. The first driving device drives the optical emitting assembly to emit first emitted light. The external first driving device is not limited by the size of the optical sensor package, etc., thus having fewer limitations. This allows the first driving device to be a high-power driving device, effectively releasing the power of the optical emitting assembly and improving its performance, such as enabling ultra-long-distance laser detection. The first driving device can also be a driving device capable of optical modulation, changing the output characteristics of the first emitted light to achieve modulation, enabling the optical sensor to meet more and more complex modulation methods, such as complex infrared light modulation.
