Abstract: The present invention relates to an optical element capable of simultaneously outputting sound from the surface of a display device with an image, the optical element comprising: a first electrode member; a first dielectric elastomer layer disposed on the first electrode member; a second electrode member disposed on the first dielectric elastomer layer; and an optical crystal layer disposed on the second electrode member. Accordingly, in the present invention, image and sound are implemented simultaneously, and thus, it is possible to prevent defects due to mismatching of the image and the sound, and a separate sound system is not required when the display device is manufactured using the optical element, thereby making it possible to reduce components of an electronic product including the display device and reduce the manufacturing cost.

Abstract: The present disclosure related to an optical fingerprint identification display and a driving method thereof. In the optical fingerprint identification display and the driving method thereof, the fingerprint identification display includes: a display panel and a processor. The display panel includes a plurality of pixels arranged in a two-dimensional matrix. The pixel includes: at least one subpixel which emits light on the basis of a first signal received from the processor; and an optical sensor which receives the light emitted from the subpixel and is reflected from a fingerprint and generates a second signal. The processor determines a touch region on the display panel, and transmits the first signal to one or more pixels included in the touch region, and identifies the fingerprint of the user on the basis of the second signal received from the pixel.
