Abstract: A foldable multi-display device includes plural display panels that define a large-sized screen by being disposed to contact each other at their one side ends when they are unfolded, and that are received in a panel housing when they are folded in a state where only their one side ends are exposed outside. The panel housing includes a housing body for receiving at least two display panel, a supporting portion defined by cutting a sidewall of the housing body to support the display panels, an upper cover mounted on the housing body to cover non-display regions of the display panels, and an opening defined on the housing body to allow the display panels to contact each other at their one side ends when the display panels are unfolded. The foldable multi-display device further includes a connecting device for foldably supporting the panel housing.

Abstract: A multi display device includes panel housings having displays. The panel housings are foldable on each other and the displays are disposed adjacent to each other when the panel housings are unfolded. A key input part is further provided to be foldable on the panel housings. Accordingly, the multi display device is easy to grasp for the user while providing the folding/folding convenience.

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.

Abstract: A separable portable multi-display device is provided. A portable multi-display device includes a main body panel housing having a first display, a sub-panel housing having a second display, and a coupling device for coupling the main body panel housing to the sub-panel housing such that at least one sides of the first display and the second display can contact each other. The panel housings are separable from and connectable to each other, a range of a border between the displays when the panel housings are interconnected being minimized so that the displays can be shown as if it is driven as a single screen.

The foldable multi-display device further includes a connecting device for foldably supporting the panel housing.

Abstract: In an information searching method, it is first determined if an input retrieval word is a sentence composed of a plurality of words. A functioning code is assigned to each word of the sentence according to its function in the sentence, and then the words are coded in basic words. Then, a database in which information is composed of a sentence having a plurality of words each of which is assigned with a functioning code and coded in a basic word is retrieved on the basis of the coded retrieval word to search information having function codes and word codes identical to those of each word of the retrieval word.

Abstract: The present invention is directed to a multi display device that can realize a large-sized screen by interconnecting a plurality of display elements. The multi display device comprises at least two flat display elements of which adjacent sides are closely contact each other to make a large-sized screen, housings receiving and supporting the display elements, respectively, light-compensating means for refracting display light from the display elements toward a center area of the adjacent sides thereof, thereby to minimize or remove the non-display area in the screen.

Abstract: A multi-display device includes at least two flat display panels foldably joined to each other with a border defined therebetween, and a light compensating member for directing light radiated from the panels toward an imaginary plane, extending from a center line of the border of the flat display panels, at a predetermined angle so that the border can be visually compensated.

Abstract: The present invention is directed to a case for a portable display device that 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 cover means for covering a side of the flat display elements, which is exposed through the opening, to protect the display elements.

Abstract: Disclosed is a portable display device including a main body, an extension portion connected to the main body such that the extension portion can be folded over and spread apart from the same, means for inputting data in the main body, and display means, provided in both the main body and the extension portion, for displaying input data and data output from the main body, at the least of the display means able to move toward the other display means to contact the same.

Abstract: In a multi liquid crystal display device, the side surfaces of liquid crystal display panels are combined with each other, and each of the liquid crystal display panels includes a pair of substrates facing each other and having liquid crystal injected therebetween. An attachment film is attached to the side surface of the liquid crystal display panel and combined to the adjacent liquid crystal display panel. Each of the liquid crystal display panels are combined by attaching the attachment films to each other.

Abstract: A smart card includes a transparent circuit board on which an integrated circuit, function switches, a power source, and other parts are mounted, an upper substrate facing the circuit board, upper and lower electrodes respectively located on facing surfaces of upper substrate and the circuit board, orthogonal to each other, orientation films coating the upper and lower electrodes, and a liquid crystal material located and sealed between the upper and lower electrodes.
