Problems solved by technology

However, when the display module is used outdoors or in a strong light environment, the infrared rays in the sunlight will pass through the display module and be imaged on the fingerprint image sensor, which interferes with normal fingerprint imaging and reduces the efficiency of fingerprint unlocking.

Embodiment Construction

[0018] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, are only for explaining the present application, and should not be construed as limiting the present application.

[0019] In related technologies, in order to increase the screen-to-body ratio of electronic devices such as mobile phones, fingerprint sensors can be placed under the screens of electronic devices such as mobile phones. The sensing surface of the fingerprint sensor is roughly parallel to the screen, or in other words, the light outside the screen is roughly perpendicular to The screen is sensed by the fingerprint sensor after passing through the screen.

[0020] It is understandable that sunlight contains many light rays of diff...

Abstract

The invention discloses an electronic device. The electronic device comprises a display module, a light supplementing lamp and a fingerprint sensor. The light supplementing lamp is arranged relative to the display module, the fingerprint sensor is arranged on one side of the display module, and the fingerprint sensor and the light supplementing lamp are arranged at an interval; the light supplementing lamp is used for transmitting target light rays through the display module; the fingerprint sensor is used for sensing the target light which is reflected by a target object and penetrates through the display module, and a light sensing light path of the fingerprint sensor inclines towards the light supplementing lamp from the fingerprint sensor. Thus, the light sensing light path of the fingerprint sensor inclines towards the light supplementing lamp from the fingerprint sensor, so that the fingerprint sensor can effectively receive target light, infrared light in sensed sunlight can be effectively reduced, the imaging quality of the fingerprint sensor is improved, and the fingerprint unlocking rate is increased.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background technique [0002] The display module on the electronic device uses infrared LED supplementary light to realize the under-screen fingerprint recognition of the display module. However, when the display module is used outdoors or in a strong light environment, the infrared rays in the sunlight will pass through the display module and form an image on the fingerprint image sensor, which interferes with normal fingerprint imaging and reduces the efficiency of fingerprint unlocking. Contents of the invention [0003] The application discloses an electronic device. [0004] The electronic device of the present application includes a display module, a supplementary light and a fingerprint sensor. The fill light is set relative to the display module, the fingerprint sensor is set on one side of the display module and spaced apart fr...
