AI Technical Summary

Technical Problem

In the existing technology, signal transmission between functional modules of electronic devices mainly relies on circuits or data lines on the circuit board, resulting in a single transmission mode and a lack of diversity.

Method used

The data transmission device, which employs a light-emitting module and an aspherical lens design, uses light transmission to achieve signal transmission. The light-emitting module emits light carrying data information, which is then collimated and focused using an aspherical lens. Finally, the light is sensed and converted into an electrical signal by a photoelectric conversion module.

Benefits of technology

It enriches data transmission modes, improves the speed and integration of short-range communication, enhances tolerance to assembly errors of aspherical lenses, and simplifies the manufacturing process.
