    Abstract: The present disclosure provides a display apparatus and a method for manufacturing the same. The display apparatus includes: a self-luminous display module, a fingerprint identification module below the self-luminous display module, at least two light shield layers between the self-luminous display module and the fingerprint identification module, and a planarization layer correspondingly arranged on one side, facing the self-luminous display module, of each light shield layer. Each light shield layer includes a plurality of mutually-independent openings; openings of one of the at least two light shield layers and openings of another of the at least two light shield layers overlap in a direction perpendicular to the fingerprint identification module; the planarization layer between two adjacent light shield layers includes a groove; and the groove and the openings do not overlap in the direction perpendicular to the fingerprint identification module, and a light blocking part is arranged in the groove.

    Abstract: A device for identifying a pattern over a first surface includes a photosensitive layer, and a light-guiding layer disposed between the photosensitive layer and the first surface. The photosensitive layer includes a plurality of photosensitive elements, each configured to convert incident light into an electrical signal. The light-guiding layer includes a plurality of light-guiding units, each positionally corresponding to one of the plurality of photosensitive elements. Each light-guiding unit includes a plurality of light-transmitting portions, each configured to guide a light beam reflected from a feature of the pattern positionally corresponding thereto to transmit therethrough and reach one of the plurality of photosensitive elements corresponding to the each of the plurality of light-guiding units. The device can be used for identification of fingerprint, as well as other biometric or non-biometric features, and has a reduced thickness and an improved accuracy for pattern identification.
