| 20090060365 | IMAGE DISPLAY DEVICE, IMAGE PROCESSING CIRCUIT, AND IMAGE PROCESSING METHOD - To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame. | 03-05-2009 |
| 20090284514 | PLASMA DISPLAY APPARATUS AND ITS DRIVE CIRCUIT - In a plasma display apparatus and its drive circuit, a period that capacitance Cxa formed between an address electrode and an X-discharge maintaining electrode and capacitance Cya formed between the address electrode and a Y-discharge maintaining electrode are charged is provided when the address electrode is driven so that the address electrode is set to high-impedance state during a discharge maintaining period to reduce apparent capacitance. Furthermore, the charge period is set in a power withdrawing period and thereafter the address electrode is set to high-impedance state to change final arrival potential for power withdrawal to a discharge maintaining voltage. | 11-19-2009 |
| 20100060609 | Touched Position Detection Method for Touch Panel - In a touched position detection method for a touch panel for detecting a touched position, based on measured values by a plurality of sensors, presence of a touch is determined when a measured value by a sensor exceeds a touch threshold. As a touch threshold, a value which cannot be attained due to a mere noise but can due to presence of a touch is set. With respect to sensors located in the vicinity of a sensor showing a high measured value, a higher weighted value is applied to modify a measured value in a touched position calculation process than that to be applied to other sensors. | 03-11-2010 |
| 20100085322 | COORDINATE INPUT DEVICE AND DISPLAY DEVICE WITH THE SAME - A capacitance detection device of a capacitance system includes: a capacitance sensor electrode for detecting a capacitance; a power source for supplying charges to be charged in the capacitance sensor electrode; an electric charge storage capacitor in which an amount of charges to be charged therein changes according to the electric charges charged in the capacitance sensor electrode; and a switch for changing a reference potential of the electric charge storage capacitor. The reference potential of the electric charge storage capacitor is changed in a period of measuring the capacitance. | 04-08-2010 |
| 20100134440 | DISPLAY DEVICE - The display device is provided with X electrodes XP and Y electrodes YP which cross with a first insulating layer in between and a number of Z electrodes which are electrically floating from each other with a second insulating layer in between. The Z electrodes are arranged so that each Z electrode overlaps both an adjacent X electrode and Y electrode. The pad portion of a first X electrode has such a form that the area is maximum in the vicinity of the fine wire portion of the first X electrode and the area is minimum in the vicinity of the fine wire portion of an adjacent second X electrode, and the area of the pad portion is smaller towards the direction in which the distance increases away from the vicinity of the fine wire portion of the first X electrode. A pulse signal is sequentially applied to one set of X electrodes or Y electrodes. | 06-03-2010 |
