Problems solved by technology

[0002] In traditional electronic devices with ultra-thin fingerprint modules, when sensing fingerprint signals, the structure of the middle frame tends to reflect part of the light, causing these light rays to enter the sensing module, so that these light rays and fingerprint signals are imaged at the same time
In this way, noise will appear in the sensed fingerprint signal

Abstract

The invention provides an electronic device including a fingerprint sensing module, a display panel and a middle frame. The fingerprint sensing module is suitable for sensing a sensing light beam reflected by a finger. The display panel is disposed on the fingerprint sensing module, and is suitable for providing an illumination beam to the finger to reflect the sensing light beam. The middle frameis disposed between the fingerprint sensing module and the display panel. The middle frame has a first surface, a second surface, and a light entrance. The first surface faces the display panel, andthe second surface faces the fingerprint sensing module. The sensing light beam passes through the light entrance to be transmitted to the fingerprint sensing module, wherein the first surface includes an annular groove recessed toward the second surface, and the annular groove has a certain distance to the light entrance.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device with a fingerprint sensing module. Background technique [0002] In conventional electronic devices with ultra-thin fingerprint modules, when sensing fingerprint signals, the structure of the middle frame tends to reflect part of the light, causing these light rays to enter the sensing module, so that the light rays and fingerprint signals are simultaneously imaged. In this way, noise will appear in the sensed fingerprint signal. Therefore, how to avoid light reflected back to the sensing module due to the structure of the middle frame is a goal that needs to be worked on in this field. Contents of the invention [0003] The invention provides an electronic device, which can avoid reflecting stray light to the fingerprint sensing module, thereby preventing the fingerprint sensing module from sensing noise light signals and effectively improving the fingerprint sensi...
