Abstract: A liquid crystal display is provided, which includes: a liquid crystal panel including a plurality of gate lines, a plurality of data lines, and a plurality of pixels including switching elements connected to the gate lines and the data lines, liquid crystal capacitors and storage capacitors connected to the switching elements; a gate driver for supplying gate voltages for driving the switching elements to the gate lines; a data driver for supplying gray voltages corresponding to applied data signals to the data lines; and a driving voltage generator for boosting a voltage according to a booster clock signal and for generating the gate voltages and a common voltage based on the boosted voltage, and the booster clock signal is synchronized with the common voltage.

Abstract: A host computer determines the location of character values in which information on the location in which each of two or more character values distinguishable from each other is arranged on the screen is determined, and sends information on the determined locations to a remote terminal. The remote terminal displays the two or more character values according to the received information, displays a screen pointer and moves the screen pointer in response to a first event. The terminal transmits the information to the host computer in response to a second event. The host computer interprets a character value indicated by the screen pointer at the time when the second event is generated, using location information of the two or more character values determined and information on the screen pointer.

Abstract: The present invention relates to a method and apparatus for inputting secret information by using multiple screen pointers. Specifically, the present invention relates to the method and apparatus which prevents the third party from detecting or recognizing the contents of the information directed to a certain system through the network and its input process. In accordance with the present invention, the method of inputting secret information by using multiple screen pointers comprises the displaying multiple screen pointers including at least two screen pointers each of which is identified by each of at least two identification symbols, respectively, defining a plurality of character regions each of which is corresponds to each of a plurality of characters, respectively, and receiving selection of at least two of the character regions by a user wherein the selection is performed by using the multiple screen pointers.

Abstract: Disclosed is a method for forming a micro groove on a PDP mold by preparing the PDP mold using a steel-based mold and rotating a CBN metal bond blade at a high speed to form the micro groove on a surface of the PDP mold at multiple steps, thereby increasing a precision thereof and reducing a manufacturing cost.

Abstract: A method for forming and polishing micro grooves in a dynamic pressure pneumatic bearing at a short time by employing the electrolytic polishing process and the micro electrolytic machining process is disclosed. The method comprises the step of forming a plurality of micro grooves in a surface of the bearing using an electrochemical electrolytic polishing process and, an electrolytic machining process.

Abstract: A method for inputting secret information by using and information processing system which comprises means for detecting events and display means, is provided. The method comprises the displaying at least two characters separately on the display means, displaying screen multi-pointers comprising at least tow screen pointers separately on screen of the display means, moving at least two screen pointers on the screen of the display means, and recording information associated with the screen multi-pointers in response to the second event detected by the detecting means.
