A display apparatus including an OLED (organic light-emitting device) substrate having a structure in which at least one blue light-emitting unit and at least one green light-emitting unit are stacked, wherein the OLED substrate generates a mixed light of a blue light and a green light; and a color controller provided on the OLED substrate to adjust color of a light generated from the OLED substrate. The color controller includes a first color control element having a plurality of first quantum dots for green conversion; a second color control element having plurality of second quantum dots for red conversion; a third color control element for presenting a blue color; a first color filter provided on the first color control element; and a second color filter provided on the second color control element.

Display apparatus

Provided is a display apparatus. The display apparatus may include a monolithic device in which a light emitting element array, a transistor array, and a color control member are monolithically provided on one substrate. The display apparatus may include a first layered structure including the light emitting element array, a second layered structure including the transistor array, and a third layered structure including the color control member, wherein the second layered structure may be between the first layered structure and the third layered structure. The light emitting element array may include a plurality of light emitting elements comprising an inorganic material. The plurality of light emitting elements may have a vertical nanostructure.

A fingerprint recognition based authentication method and apparatus is disclosed. The authentication apparatus may obtain an input fingerprint from a touch input of a user, determine an input number corresponding to the input fingerprint using preregistered fingerprint-number mapping information, and authenticate the user based on whether an input number sequence corresponding to an input fingerprint sequence is identical to a reference number sequence.

Method and apparatus for authentication based on fingerprint recognition

Beam steering devices and optical apparatuses including the beam steering devices are provided. A beam steering device includes a light source configured to generate input lights having first different wavelengths, a multiplexer configured to simultaneously receive the generated input lights, and multiplex the received input lights into a multiplexed light, and an optical splitter configured to split the multiplexed light. The beam steering device further includes an optical modulator configured to modulate the split light, and an emitter configured to simultaneously emit output lights having second different wavelengths to different points arranged in a first direction, based on the modulated light.
