Abstract

The invention provides a fingerprint recognition component comprising a light guide panel, at least one active light source and at least one fingerprint module group. At least one active light sourceis arranged on one of the side surfaces exactly facing the light guide panel. At least one fingerprint module group is arranged on the other side corresponding to the active light source of the lightguide panel. The light guide panel is provided with a fingerprint contact surface used for fingerprint pressing. The light emitted by at least one active light source penetrates through the side surface to be reflected inside the light guide panel to be irradiated to the fingerprint contact surface on which the fingerprint to be recognized is pressed and totally reflected with the fingerprint to be recognized. The totally reflected light of the light guide panel is incident to at least one fingerprint module group. At least one fingerprint module group acquires and recognizes the fingerprint image according to the totally reflected light. The invention also provides a display device equipped with the fingerprint recognition component and an electronic device equipped with the display device.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a fingerprint recognition component, a display device provided with the fingerprint recognition component, and an electronic device provided with the display device. Background technique [0002] With the rapid development of biometric technology, fingerprint recognition technology has been widely used in electronic devices such as smart phones and tablet computers. Existing fingerprint recognition components can be mainly divided into capacitive fingerprint recognition components, optical fingerprint recognition components, thermal fingerprint recognition components, and ultrasonic fingerprint recognition components. Factors have become the most widely used fingerprint identification components. [0003] The fingerprint recognition module of the fingerprint recognition component on the existing smart phone is usually arranged on the front of the smart phone. Therefore, the f...
