Transparent display apparatus and method for controlling the same

摘要

There are provided a transparent display apparatus and a method for controlling the same. The transparent display apparatus includes a transparent display unit that includes an emissive area and a transmissive area and is configured to display a video, an optical sensor configured to measure the amount of light, and a light shielding unit that is disposed on one surface of the transparent display unit and is configured to adjust transmittance on the basis of the amount of light.

1. An apparatus comprising:
a transparent display unit including an emissive area and a transmissive area; a light control unit to adjust a transmittance of the transmissive area; and a controller on an integrated circuit, electrically connected to the transparent display unit and the light control unit, the controller to control a contrast ratio of the emissive area and the transmissive area on a basis of a target contrast ratio and a brightness of ambient light wherein the target contrast ratio is controlled by the controller using an equation:target⁢⁢contrast⁢⁢ratio=X⁢:⁢1=Lmax+Lfront×Treflect+Lback×Tself×TvarLmin+Lfront×Treflect+Lback×Tself×Tvar⁢:⁢1 wherein X:1 is the target contrast ratio of the apparatus, and wherein Lmax is a maximum luminance of the apparatus, Lmin is a minimum luminance of the apparatus, Lfront is a luminance of light incident onto a front surface of the apparatus, Lback is a luminance of light incident onto a rear surface of the apparatus, Treflect is a light reflectivity of the apparatus, Tself is a self-transmittance of the apparatus, and Tvar is a light transmittance of the light control unit.
