Embodiment Construction

[0046] In the specific description of the embodiments of the present application, it should be understood that when a substrate, frame, sheet, layer or pattern is referred to as being "on" or "under" another substrate, another sheet, another layer or another pattern , it may be "directly" or "indirectly" on another substrate, another sheet, another layer or another pattern, or one or more intermediate 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.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the...

Abstract

The invention discloses a biological characteristic detection system. The biological characteristic detection system comprises a display device and a detection module, the display device comprises a protective cover plate, a display panel and a backlight module, and the display panel is positioned below the cover plate. The backlight module comprises a light guide plate and a light source, the light guide plate is located below the display panel and comprises a top face and a bottom face which are oppositely arranged and a side face located between the bottom face and the top face, and the topface faces the display panel. The light source is located at one side of the light guide plate and is used for emitting backlight beams to the side faces, and the light source is also used for emitting a detection light beam towards the upper part of the protective cover plate; the detection light beam penetrates through the protective cover plate to reach an external object, and the detection light beam is used for the biological characteristic detection of the external object. A wavelength of the detection beam is different from a wavelength of the backlight beam, and the detection module is located below the display device. The system has a better under-screen biological feature detection effect and the better user experience.

Description

technical field [0001] The present application relates to the field of optoelectronic technology, and in particular to a biological feature detection system. 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 mobile phones is to have a higher screen-to-body ratio and have functions such as front camera Selfie and face recognition. As the functions supported by the biometric detection system become more and more abundant, the number of components that need to be set is also increasing, and a part of the display area on the front of the biometric detection system needs to be occupied, which affects the appearance and user experience. [0003] Recently, in order to achieve a full-screen or near-full-screen effect, off-screen biometric detection tech...
