Abstract

Embodiments of the present invention provide a fingerprint identification device, a display panel, a display device, and a fingerprint identification method, which belong to the technical field of organic light-emitting displays. The fingerprint identification device includes a control module and a light emitting module and a light receiving module respectively connected with the control module signal, wherein the light emitting module is used to emit light signals to the identification area containing fingerprint information based on the control instructions of the control module; For receiving the reflected light signal reflected by the identified area; and the control module is used for determining the control command corresponding to the light emitting module, converting the reflected light signal into an electrical signal, and performing fingerprint recognition operation based on the electrical signal. The fingerprint identification device provided by the embodiment of the present invention can solve the problem that the structure of the existing fingerprint identification device is complex and the identification area is a fixed area.

Description

technical field [0001] The invention relates to a fingerprint identification device, a display panel, a display device and a fingerprint identification method, and belongs to the technical field of organic light-emitting displays. Background technique [0002] With the popularity of smart devices (such as mobile phones, tablet computers, etc.), smart devices involve more and more private information related to users (such as photos, payment passwords, etc.). Therefore, in order to protect information security, existing smart devices are usually based on Fingerprint recognition technology realizes the encryption of smart devices. [0003] However, the fingerprint recognition function implemented by sensors or ultrasonic technology in existing smart devices has many defects. For example, the hardware structure is complex, the recognition accuracy is not high, and the recognition area is a fixed area. Contents of the invention [0004] Embodiments of the present invention p...
