  • TOUCH CONTROLLER HAVING INCREASED SENSING SENSITIVITY, AND DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE AND SYSTEM HAVING THE TOUCH CONTROLLER
    Publication number: 20120229421
    Abstract: A touch controller includes a touch data generator that is connected to a plurality of sensing lines, the touch data generator sensing a change in capacitance of a sensing unit connected to each of the sensing lines and generating touch data by processing the sensing signal corresponding to the result of sensing; and a signal processor that controls a timing of generating the touch data by receiving at least one piece of timing information for driving a display panel from a timing controller, and then providing either the timing information or a signal generated from the timing information as a control signal to the touch data generator.

  • Value Adjustment Methods, Value Adjustment Signal Processing Apparatus, and Image Display Systems Using the Same
    Publication number: 20110292071
    Abstract: A method of adjusting value includes calculating a value of saturation from an input image signal, and adjusting a value of value of the input image signal according to a calculated saturation value. In the method, the value of value of the input image signal is adjusted by using a value adjustment algorithm for determining a value adjustment rate that decreases the value according to the saturation value.
