摘要:
A flat panel display device is provided with an increased viewing angle having good dark versus light imaging contrast. The display device includes a display panel, a first optical unit, and a second optical unit. The display panel includes a liquid crystal layer that is driven in a vertical alignment mode. The first optical unit includes a negative C-plate and a first polarizer having a first absorption axis. The second optical unit includes a biaxial compensation plate having a refractive indices coefficient, (nx−nz)/(nx−ny) of more than 0.45 and less than 0.55, and a second polarizer having a second absorption axis crossing the first absorption axis. The biaxial compensation plate has a refractive indices relationship of nx>nz>ny such that dispersion of polarization states of colored light rays passed through the C-plate and the liquid crystal layer may be minimized and gathered about an extinction point, thereby improving contrast at side viewing angles.

The present invention relates to a sensing device of an emotion signal and a method thereof capable of recognizing and analyzing the change in emotion by collecting at least one of the bio signals and peripheral environmental signals, guiding the state of emotion to a user, and sharing emotion information with authorized persons and communicating it between them. The sensing device of the emotion signal according to the embodiment of the present invention includes a sensing signal processor that senses a plurality of bio signals and peripheral environment signals of a user; an emotion signal processor that generates emotion signals representing the emotional state of the user for each of the sensed bio signals and collects the emotion signals to generate an emotion index; and an emotion signal communication unit that optionally transmits the emotion signals and the emotion index to external authorized devices.

Provided is a method for preparing a compound semiconductor substrate. The method includes coating a plurality of spherical balls on a substrate, growing a compound semiconductor epitaxial layer on the substrate coated with the spherical balls while allowing voids to be formed under the spherical balls, and cooling the substrate on which the compound semiconductor epitaxial layer is grown so that the substrate and the compound semiconductor epitaxial layer are self-separated along the voids. The spherical ball treatment can reduce dislocation generations. In addition, because the substrate and the compound semiconductor epitaxial layer are separated through the self-separation, there is no need for laser lift-off process.

A method for recognizing an image photographed by a camera and translating characters in connection with an electronic dictionary is provided. The method includes directly selecting an area to be recognized from the photographed character image and performing character recognition, translating and recognizing characters of a user's selected word in connection with dictionary data, and displaying translation result information of user's selected character or word in connection with dictionary data on a screen device. The recognition includes providing information on location of the selected character image area and location of the recognized character string words to the user, and then translating a character string or word in a location area selected by the user. The electronic dictionary-connected search and translation is for searching the character or word selected in connection with the electronic dictionary database, and providing translation result to the user.

In a plasma display and a driving method thereof, an average grayscale value of all discharge cells are detected from an input video signal, and an auxiliary reset waveform is supplied to reset periods of all subfields when the detected average grayscale value is lower than a predetermined reference grayscale value. The reference grayscale value is established to be an average grayscale value of a video signal for selecting all of the discharge cells as turned-on cells in a subfield having a minimum weight value. Particularly, the reference grayscale value may be established to be 0 that is the same as an average grayscale value of a full-black video signal.
