Embodiment Construction

[0058] In the detailed description of the embodiments of the present invention, it should be understood that when a substrate, sheet, layer or pattern is referred to as being "on" or "under" another substrate, another sheet, another layer or another pattern, it It may be "directly" or "indirectly" on another substrate, another sheet, another layer or another pattern, or one or more intervening layers may also be present. For the purpose of clarity, the thickness and size of each layer in the drawings of the specification may be exaggerated, omitted, or schematically represented. Also, the size of elements in the drawings does not utterly reflect an actual size.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Base...

Abstract

The invention discloses an optical detection device. The optical detection device comprises a display device, a transmitting module and a detection module, the display device comprises a protective layer, a display panel and a backlight module. The transmitting module comprises a light emitting unit and an adjusting unit, and the adjusting unit is used for reducing the divergence angle of the detection light beams emitted by the light emitting unit. At least part of the detection module is located below the backlight module, and the detection module is used for receiving a detection light beamreturned from an external object and converting the detection light beam into an electric signal so as to obtain biological characteristic information of the external object. The adjusting unit adjusts the detection light beam, and the divergence angle of the detection light beam in a first plane is smaller than the divergence angle of the detection light beam in a second plane. The invention also discloses a group of display devices and an electronic apparatus.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to an optical detection device and electronic equipment for realizing biological feature detection by using optical imaging. 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, tablet computers, and cameras. At present, the development trend of electronic products such as mobile phones is to have a higher screen-to-body ratio and have fingerprint detection or other biometric detection functions. In order to achieve a full-screen or near-full-screen effect and make electronic products have a high screen-to-body ratio, under-screen biometric detection technology has emerged as the times require. However, for liquid crystal display screens and other non-self-luminous displays, there is no better solution in the prior...
