Problems solved by technology

The area of ​​the display area is reduced due to the need to reserve a non-display area for the front camera and the ambient light sensor to receive the light beam
The non-display area cannot be used for display, resulting in a low screen-to-body ratio of the electronic device and poor visual aesthetics
In addition, some electronic products place the ambient light sensor under the display to obtain a high screen-to-body ratio. Due to the impact of the display on the ambient light transmittance, this will affect the performance of the ambient light sensor and the user experience is poor.

Abstract

The invention discloses an optical detection unit which is used for receiving a detection light beam penetrating through a lens assembly and converting the received detection light beam into an electric signal. The electric signal is used for generating an image or sensing light intensity, and the optical detection unit comprises a first optical chip which is used for receiving the detection light beam and converting the detection light beam into an electric signal and generating a corresponding image, and a second optical chip which is used for receiving the detection light beam and converting the detection light beam into an electric signal so as to sense the light intensity of the detection light beam. The invention further discloses an optical detection device and electronic equipment.

Description

technical field [0001] The present application relates to the field of optoelectronics, in particular, to an optical detection unit, an optical detection device and electronic equipment. Background technique [0002] With the advancement of technology and the improvement of people's living standards, users require more functions and stylish appearances for electronic products such as mobile phones and tablet computers. At present, the development trend of electronic products such as mobile phones is to have a high screen-to-body ratio, such as a full screen with a screen-to-body ratio of more than 90%. However, when current front-facing cameras, ambient light sensors and other devices are applied to mobile phones, they will occupy the display area of ​​the screen, resulting in a decrease in screen-to-body ratio. For example, in order to be able to detect the intensity of ambient light or receive ambient light for imaging, it is necessary to open a window on the cover glass ...
