Abstract: A display apparatus is disclosed. The display apparatus includes a display including an active area for displaying an image and a black matrix adjacent to the active area, and an optical sheet attached onto the display. The optical sheet includes a Fresnel pattern formed on the black matrix and a portion of the active area. The Fresnel pattern includes a plurality of peaks and a plurality of valleys, which are formed such that depths between the peaks and the valleys gradually increase from the active area to the black matrix. Therefore, it is possible to view an image in front of the black matrix, on which an image is not actually displayed.

Abstract: The present invention provides a depth image generation apparatus comprising: a light source for generating light to be emitted toward an object in order to solve an SNR problem caused by resolution degradation and an insufficient amount of received light, while not increasing the amount of emitted light when photographing a remote object; a first optical system for emitting, as a dot pattern and at the object, the light generated by the light source; an image sensor receiving the light reflected by the object, so as to convert the received light into an electrical signal; an image processor for acquiring depth data through the electrical signal; and a control unit connected to the light source, the first optical system, the image sensor and the image processor, wherein the control unit controls the first optical system so as to scan the object by moving the dot pattern in a preset pattern.
