Abstract

The invention discloses a display panel, a display device and a manufacturing method of the display panel. The display panel comprises a substrate, a driving circuit layer and a first film layer, wherein the first film layer comprises a first opening and a plurality of second openings, a light-emitting element electrically connected with the driving circuit layer is arranged in the first opening,the vertical projections of the second openings on the substrate are not overlapped with the vertical projection of the driving circuit layer on the substrate, and collimation structures are formed inthe second openings; and the display panel further comprises a fingerprint recognition unit, and the vertical projection of the fingerprint recognition unit on the plane where the substrate is located is at least partially overlapped with the collimation structures. The invention further provides a display device comprising the panel structure and a manufacturing method of the panel structure. According to the invention, the collimation structures are manufactured by reusing the pixel defining layer, the thinning of the panel is realized, the light is guided by the collimation structure and then is received by the fingerprint identification unit, and the detection sensitivity of the fingerprint identification unit is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device including the display panel, and a manufacturing method of the display panel. Background technique [0002] Fingerprint identification is one of the most widely used and relatively cheap identification technologies in biometrics. In recent years, the market growth rate has been in the leading position of identification technology. At present, fingerprint recognition technology is mainly used in the field of intelligent display and attendance system, among which optical recognition is an earlier fingerprint recognition technology. With the rapid development of the display field, the full screen has become the development trend of the future smart phone field. Subsequently, in order to pursue a screen ratio close to 100%, the smart phone on the market began to adopt the optical fingerprint unlocking technology under the screen. . [0003...
