Luminous fingerprint recognition panel and fingerprint recognition display device including same

Abstract

The invention provides a luminescent fingerprint identification panel and a display device including the same: it can be overlapped with the display panel without reducing the display performance, and can scan fingerprint images with high accuracy without being affected by display light and external light by using its own luminous element. The luminous fingerprint identification panel of the present invention includes: an insulating substrate; and a plurality of unit light-emitting-light-receiving pixels arranged in a matrix on the above-mentioned insulating substrate, and the above-mentioned unit light-emitting-light-receiving pixels include: a light-emitting part, including at least a part of transparent light-emitting an element; a light-emitting switch section for controlling the operation of the above-mentioned light-emitting section; and a light-receiving section including at least a partially transparent photosensor element.

Description

technical field [0001] The present invention relates to a tablet fingerprint image scanning device, a fingerprint identification panel including the same to scan a fingerprint image on a display screen, and a display device including the same. Background technique [0002] Recently, as security issues of information communication providers have come into focus, security-related technologies are also emerging in the field of personal portable information communication devices such as smartphones and tablet computers (PCs). Electronic commerce etc. using people's portable devices is also gradually increasing, especially, with the development of financial and information communication fusion technology called FinTech (FinTech), the following technologies are developed and utilized, that is, using fingerprints, iris, face, Biometric information such as voice and blood vessels to identify and authenticate individuals. Among various biometric information verification technologies...

AI Technical Summary

Problems solved by technology

However, the optical method using the photosensor is affected by the internal light pattern emitted through the display panel or the external light incident from the external environment, thereby easily causing a problem that the accuracy of fingerprint recognition decreases.

For example, the internal light emitted through the display panel has a long distance from the fingerprint and has no directionality, so it has problems with scattering and mutual interference

Moreover, due to the integrated configuration of the photosensor array, it is easy to cause the problem that the display performance of the display panel is reduced.
