Abstract: A display apparatus includes a signal receiver configured to receive a broadcast signal, a signal processor configured to process the received broadcast signal, a display configured to display an image based on the processed broadcast signal, a user input receiver configured to receive a user input, a storage, and a controller. The controller is configured to control the storage to store information about an external device being mapped to a channel among a plurality of channels in accordance with the user input, display the information about the external device corresponding to the mapped channel, and control the external device via the mapped channel. Thus, a user may easily register the external device with a channel simply by placing an input device, such as a remote controller or the like, in proximity to the external device while viewing a broadcast.

Abstract: Disclosed herein is an electrochromic device having a structure in which atoms of an electrolytic layer and an ion storage layer are mixed with each other. The electrochromic device includes an active layer configured to provide a transparent state by a protonation and a reflective state by a deprotonation, an ion storage layer which stores a proton, an electrolytic layer which is provided between the active layer and the ion storage layer and used a medium through which the proton is moved, and a mixed layer having constituent elements of the ion storage layer and the electrolytic layer.

Abstract: An apparatus for controlling black stretch includes a black stretching unit, an offset adjusting unit and an output unit. The black stretching unit performs black stretch processing on a video signal less than or equal to the maximum value of a black stretch control range in response to a slope of black stretch. The slope of black stretch corresponds to a region between a minimum value and a maximum value of the black stretch control range. The offset adjusting unit adjusts an offset of the black-stretched video signal. The output unit outputs an output video signal corresponding to the offset-adjusted video signal when the offset-adjusted video signal has a positive value in a region less than or equal to the minimum value, and outputs the output video signal corresponding to 0 when the offset-adjusted video signal has a negative value in the region less than or equal to the minimum value.
