  • Patent number: 7907118
    Abstract: Provided is a user interface apparatus with improved operability thereby allowing a desired alternative to be selected from a plurality of alternatives more smoothly than by conventional techniques. When an instruction is received from a user to display a contents selection reception screen, eight contents corresponding to eight ordinal ranks are selected from among managed contents at intervals of n/8, and are set as selectable alternatives, and a table is created in which the ordinal ranks of the eight selectable alternatives are corresponded with key codes respectively, where each key code represents a press directed to a corresponding one eight press sensors. Based on the created table, a GUI screen is displayed for receiving selection of one of the ordinal ranks.

  • Patent number: 7889166
    Abstract: A liquid crystal display with improved color reproducibility and image quality is presented. The liquid crystal display includes a liquid crystal panel assembly including a plurality of pixels, a signal controller, and a data driver. The signal controller stores a dithering data patterns, selects one of the dithering data patterns based on input image data having a first bit number, and converts the input image data to output image data having a different bit number using the selected dithering data pattern. The data driver applies data voltages to the pixels, the data voltages corresponding to the output image data from the signal controller. Frequency of the input image signal and the output image signal from the signal controller is each about 120 Hz, and the dithering data patterns are repeated every eight frames. The signal controller includes a look-up table that stores the dithering data patterns.

  • Patent number: 7884653
    Abstract: A source driver includes four output switches, two resistors, and a charge-sharing switch. The first output switch and the first resistor are coupled in series to a first output channel of the source driver. The second output switch and the second resistor are coupled in series to a second output channel of the source driver. The third output switch is coupled in parallel to the first output switch. The fourth output switch is coupled in parallel to the second output switch. The charge-sharing switch is coupled between the first resistor and the second resistor. The third output switch and the fourth output switch are controlled to adjust the resistance of the output current path of the source driver.

  • Patent number: 7864161
    Abstract: A system and method for detecting at least two-finger input on a touch screen of a display such as computer, etc. includes a display screen; a sensing grid arranged for sensing touch on said display screen; a plurality of electrodes connected electrically to the sensing grid. A controller receives an output from the sensing grid, and a module identifies at least two points on the grid indicating locations of the display screen that have been touched by a user and identifies a geographic portion of the display screen to be identified based on said at least two points. As the position of the fingers are relative to the position of the screen via change in a direction of a Z-coordinate, a variable zoom can be provided by the sensing grid commensurate with different distances that the multiple fingers are sensed from the display screen.

  • Patent number: 7808456
    Abstract: A driving system and method for electroluminescent displays which by connecting the electroluminescent elements that have been lighted up to the electroluminescent elements that are to be lighted up causes charge to be shared among the elements, so as to increase the voltage level at the anodes of the electroluminescent elements which are to be lighted up, thereby reducing the power consumption and increasing the response speed.

  • Patent number: 7796107
    Abstract: An organic light emitting display is disclosed capable of displaying an image of uniform luminance regardless of a leakage current. The display includes scan and data lines crossing each other. The display further includes red, green, and blue pixels having red, green, and blue organic light emitting diodes (OLEDs), respectively. Switch sections are respectively included in the red, green, and blue pixels for transferring a data signal to the data lines according to a scan signal from the scan lines. Driving circuits are respectively included in the red, green, and blue pixels for supplying a current to red, green, and blue OLEDs connected thereto according to the data signal from the switch sections. At least one of the respective switch sections included in the red, green, and blue pixels has a different number of transistors than at least one other of the respective switch sections.

  • Patent number: 7786980
    Abstract: A method and apparatus for preventing staining of a display screen by a user's fingers, by encouraging a user not to touch the surface of a display screen while using a graphic user interface associated with the display screen includes determining a first threshold distance from the display screen within which a user's finger may be detected, determining a second threshold distance from the display screen within which a user's fingers may be detected, the second threshold distance being shorter than the first threshold distance, first detecting when a user's finger is within the first threshold distance, indicating to the user, upon a detection in the first detecting step, that the user's finger has entered a zone proximate to the screen where interaction with a graphical user interface (GUI) is enabled, the GUI enabling manipulating various display functions by movements of the user's finger, second detecting when a user's finger is within the second threshold distance, and indicating to the user, upon a det
