Embodiment Construction

[0030] In the specific description of the embodiments of the present application, 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.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the accompanying drawings in the embodiments of the application. Apparently, the described embodiments are only part of the embodiments of the application, not all of them. Based...

Abstract

The invention discloses an optical detection device, which comprises a protective layer, a display module, a detection light source, a reflection structure and a detection module, wherein the protective layer comprises a first surface and a second surface opposite to the first surface; the display module is located below the protective layer and used for emitting visible light beams through at least part of the protective layer to realize picture display; the detection light source is used for emitting a detection light beam to an external object outside the protective layer; at least part ofthe reflection structure is located below the second surface, and the reflection structure is used for reflecting at least part of the detection light beam and then projecting the detection light beamto the external object through the protective layer; and the detection module is positioned below the second surface and is provided with a view field area on the first surface, when the external object is in contact with the view field area, and the detection module can receive the detection light beam which is retuned by the external object and penetrates through the protective layer and at least part of the display module and convert the received detection light beam into a corresponding electric signal.

Description

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