Abstract: A three-dimensional (3D) backlight unit and a display apparatus including the 3D backlight unit are provided. The 3D backlight unit may include a light source configured to emit light, and a light guide plate configured to guide the light emitted by the light source. The light guide plate may include output elements that allow a portion of the light guided by the light guide plate to be directed to exit the light guide plate, and a cross section of at least one of the output elements has an inverted trapezoid form. The output elements may allow a portion of light reflected from a lower surface of the light guide plate to an upper surface of the light guide plate to be directed to exit the light guide plate.

Abstract: A head up display (HUD) system and an optical element for an HUD are provided. The optical element includes a Fresnel pattern layer configured to enlarge a virtual image for the HUD, a multiband coating layer formed on the Fresnel pattern layer, the multiband coating layer configured to receive light of multiple wavelength bands from a light source and transmit a portion of the light of the multiple wavelength bands based on a transmittance set with respect to the multiple wavelength bands. The multiple bands may include a wavelength band indicating a red light, a wavelength band indicating a green light, and a wavelength band indicating a blue light.
