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 a plurality of first pixels having an emissive area on which an image is displayed and a transmissive area on which a background is projected; a light control unit that includes a plurality of second pixels disposed on one surface of the transparent display unit; and a transmittance control device that extracts at least one object from an image displayed by the transparent display unit and controls transmittance of an area, which corresponds to the light control unit and the extracted object.

Transparent display apparatus with adjustable transmissive area and a method for controlling the same

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.

Transparent display apparatus and method for controlling the same

A multi-touch sensing method and apparatus are described. The multi-touch sensing method includes: storing, in a memory, coordinate values of a first dead zone and coordinate values of a second dead zone existing between first and second pair of image sensors, respectively; calculating coordinate values of touch points from images obtained by the first and second pairs of image sensors; comparing the coordinate values of the touch point and the coordinate values of the dead zones to identify the location of the dead zone to which the touch point belongs; selecting the coordinate values calculated in the third step if the coordinate values of the touch point belong to the first dead zone; and selecting the coordinate values calculated in the second step if the coordinate values of the touch point belong to the second dead zone.
