Light guide assembly and detection method of light guide assembly

Abstract

The invention discloses a light guide assembly and a detection method of the light guide assembly, and belongs to the technical field of electronics. The light guide assembly comprises: a light guide main body; a sensing component which is arranged on the light guide main body, wherein the sensing component is provided with a signal output port; and a detection circuit, wherein a detection pin of the detection circuit is electrically connected with a signal output port of the induction part, and the detection circuit determines whether the light guide body is broken or not according to a detection signal output by the induction part. The light guide assembly provided by the embodiment of the invention can identify whether the light guide main body is broken or not, and can solve the problem that the breakage of the light guide column is difficult to find due to the fact that the light guide column is arranged in the electronic equipment in the prior art.

Description

technical field [0001] The application belongs to the field of electronic technology, and in particular relates to a light guide component and a detection method of the light guide component. Background technique [0002] With users' pursuit of the ultimate user experience, users have higher and higher requirements for the performance and appearance of mobile terminals such as mobile phones and tablet computers. In order to improve user experience, the screen area of ​​mobile terminals is getting larger and larger, and the screen-to-body ratio (the ratio of the screen display area to the screen area) is also getting higher and higher. Correspondingly, the top of the screen of the mobile terminal is used to place the front camera , infrared sensors, photosensitive sensors and other devices are getting narrower and narrower. [0003] In the process of implementing this application, the inventor found that in the prior art, in order to avoid devices such as infrared sensors an...

AI Technical Summary

Problems solved by technology

Since the light guide column is a fragile material, it is easy to break during the transportation, assembly or use of the mobile terminal. However, the light guide column is installed inside the mobile terminal, and it is difficult for assemblers and users to find that the light guide column is broken

This will affect the data collection of the sensor, thereby affecting the realization of functions such as automatic adjustment of screen brightness, close-to-off screen during calls, and anti-touch functions of mobile terminals.
