Abstract: A case for a portable display device can realize a large-sized screen by interconnecting a plurality of display elements, When the display elements are unfolded, the adjacent sides of the display elements closely contact each other, thereby minimizing the non-display area. When the display elements are folded, the outer surface of the display elements can be protected. The case includes a foldable panel housing receiving at least two flat display panel elements. The panel housing is provided with an opening such that when the panel housing is unfolded, the adjacent sides of the flat display elements closes contact each other. The case further includes a hinge supporting member for providing the folding/unfolding operation of the panel housing and a cover for covering a side of the flat display elements, which is exposed through the opening, to protect the display elements.

Abstract: The present invention discloses a search engine system with coded information and a search method using the same. The system includes a key word input part, a database for storing information as word codes which are not real standard words, and a central process unit for assigning a word code assigned to a standard word to a word input through the key word input part or a client system, and searching information corresponding to the word code of the input word through the database. In the invention, when key word(s) relating to information to be searched are input through the information input system, the input words are coded and the search is performed using the word codes through the database, thereby searching the information more precisely. In addition, since a plurality of different words having similar or same meanings are coded as one standard word code according to a simple coding rule and stored in the database, the process time for searching the information can be greatly reduced.
