Abstract

The invention provides a fingerprint identification apparatus, a display panel and a fingerprint identification method belonging to the technical field of displaying, and can solve the problem that the fingerprint identification apparatuses of the existing organic light emitting diode display products occupy the frame areas and are not conducive to the narrow bezel design. In the fingerprint identification apparatus of the invention, a collimator transmits the collimated light reflected through a fingerprint and blocks the scattered light, which is equivalent to that the light emitted by a light-emitting layer is reflected by a finger and the approximately collimated reflected light can pass through the collimator area, and the tilted light will be blocked by the collimator. A sensor identifies the wave crest and the wave ridge according to the light transmission area of the collimator. The fingerprint identification apparatus is simple in making process, high in practicality, and is suitable for fingerprint acquisition and identification in an organic light-emitting diode display area.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a fingerprint identification device, a display panel and a fingerprint identification method. Background technique [0002] An organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is also called an organic electroluminescence display (Organic Electroluminescence Display, OELD). Among various types of flat panel displays, OLED displays have the advantages of wide viewing angle, high brightness, high contrast ratio, low driving voltage and fast response. [0003] Fingerprint is an invariable feature that is unique and distinguishable from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of these ridges and valleys usually include the bifurcation of ridges, the Details such as ends, arches, tent-like arches, left-handed, right-handed, spiral or double-handed, determine the uniqueness of the fi...
