Abstract: A system and a method for providing a sign language service are provided. The system includes a first terminal that generates at least one piece of first message data corresponding to a message to be delivered by a first user. The system also includes a server that converts the first message data received from the first terminal into first operation data corresponding to an operation of a robot. The system also includes the robot that performs an operation according to the first operation data received from the server. The server sorts two or more pieces of first operation data based on a transmission order according to a predetermined criterion, when identifying the two or more pieces of first operation data, and transmits the pieces of sorted first operation data to the robot. The robot performs the operation, based on the pieces of sorted first operation data.

Abstract: An object synchronization apparatus includes a memory storing computer-executable instructions and at least one processor that accesses the memory and executes the instructions. The at least one processor: creates a virtual object corresponding to a source code of a user in a virtual space, in response to a compiling request based on the source code; performs verification for the created virtual object; performs synchronization between the verified virtual object and a real object, in response to a control request for the verified virtual object; and creates a sub-virtual object corresponding to a detected target object in the virtual space when the synchronized real object detects the target object.

Abstract: A display substrate includes a plurality of gate wirings, a plurality of source wirings, a plurality of pixel portions, an electrical short pad part and a short element. The electrical short pad part is formed in a peripheral area surrounding the display area and formed from at least one of the gate metallic layer and the source metallic layer to receive a common voltage. The short element makes contact with the electrical short pad part and has electric conductivity. The electrical short pad part includes a first metallic layer and a second metallic layer in sequence, and the second metallic layer has greater ionization energy than the first metallic layer. The electrical short pad part is exposed onto the surface of the display substrate. Accordingly, an extra cover electrode for preventing the electrical short pad part from corrosion may be omitted, so that static electricity is prevented from being applied into the display substrate.

Abstract: An array substrate includes a transparent substrate, a switching device, an insulation layer, a pixel electrode, a reflective plate and an inner polarization layer. The transparent substrate has a reflective region and a transmissive region. The switching device is formed in the reflective region. The insulation layer is formed on the transparent substrate to cover the switching device. The insulation layer has a contact hole that exposes a portion of a drain electrode of the switching device. The pixel electrode is electrically connected to the drain electrode of the switching device through the contact hole. The reflective plate is electrically connected to the pixel electrode and is disposed at the reflective region. The inner polarization layer covers the reflective plate. Thus the white luminance and the contrast ratio of an LCD apparatus having the above array substrate are enhanced.

Abstract: A display apparatus includes at least one pixel region having a reflection region and a transmission region. A polarizing layer of the pixel region may be formed on an uneven underlying structure surface, and may have an even opposing surface. The polarizing layer may have a first thickness the reflection area of the pixel region and a second, substantially larger thickness in the transmission area of the pixel region. The display apparatus may comprise an array substrate, a color filter substrate, and a liquid crystal material. In an array substrate, a color filter substrate and a liquid crystal display panel having the array substrate and the color filter substrate, an array substrate includes a first inner polarizing layer having a first portion where a front light is reflected and a second portion through which a back light passes. The second portion is substantially thicker than the first portion. The color filter substrate includes a second inner polarizing layer.

Abstract: A timing control device for liquid crystal display including odd data driver ICs and even data driver ICs, both group of ICs being arrayed serially on one part of the liquid crystal display panel, color signals being converted to appear alternately at the odd data and the even-data according to a number of channels of driver IC, the odd data and the even data being transmitted to the odd data driver ICs and the even data driver ICs respectively, each one of the odd data driver ICs and the even data driver ICs simultaneously operating the liquid crystal display, effecting driver frequency to be reduced, the color signal being similar type to a single bank type, enabling the data driver ICs to be arranged on one face of the liquid crystal display panel, effecting compact design of the data driver ICs.
