20090315816 | DISPLAY APPARATUS - A display apparatus includes a display panel, a light generator disposed under the display panel to generate light, a light sensor disposed between the display panel and the light generator and which senses a first portion of the light generated by the light generator and reflected by an object disposed above the display panel, a light diffuser disposed between the display panel and the light sensor, and an image processor which provides image data corresponding to the first portion of the light sensed by the light sensor to the display panel. | 12-24-2009 |
20100026639 | LIQUID CRYSTAL DISPLAY AND TOUCH SENSING METHOD THEREOF - A liquid crystal display includes a liquid crystal panel that has a plurality of pixels and a plurality of sensors, and a touch sensing circuit that compares a sensing voltage detected by at least one sensor with a reference voltage that corresponds to the at least one sensor to determine the at least one sensor is touched. A level of the reference voltage is calibrated by taking operation characteristics of the sensors into consideration. | 02-04-2010 |
20100110028 | TOUCHSCREEN DISPLAY SUBSTRATE AND TOUCHSCREEN DISPLAY APPARATUS HAVING THE SAME - A touchscreen display substrate includes; a plurality of pixel parts including a plurality of first pixel rows arranged in a first direction, and a plurality of pixel columns arranged in a second direction substantially perpendicular to the first direction, wherein each of the plurality of pixel parts includes a pixel electrode, and a plurality of sensing parts which sense a touch state, the sensing parts being disposed in an area corresponding to the plurality of pixel parts, and being sequentially arranged in the first direction between adjacent pixel parts of first plurality of pixel columns. | 05-06-2010 |
20100156819 | METHOD AND APPARATUS FOR DETECTING A TOUCH POSITION, AND TOUCHSCREEN DISPLAY APPARATUS HAVING THE SAME - A method for detecting a touch position includes integrating a readout current detected at a sensing part to generate an integrated readout voltage, converting the integrated readout voltage into a digital converted readout voltage data and compensating a variation of the digital converted readout voltage data to determine whether the sensing part is touched. | 06-24-2010 |
20110169769 | TOUCH DISPLAY SUBSTRATE AND TOUCH SCREEN DISPLAY APPARATUS HAVING THE SAME - A touch display substrate comprises a base substrate, a plurality of pixel portions, a sensing element portion and a sensing line portion. The pixel portions can be arranged in at least one pixel column and at least one pixel row on the base substrate, and may include a pixel electrode. The sensing element portion may be disposed in a first column between a first pixel column and a second pixel column, and senses a touch. The sensing line portion may be disposed in a second column between adjacent pixel columns and coupled to the sensing element portion, and the second column is different from the first column. The sensing line portion may be disposed between pixel columns different from the pixel columns where the sensing element portion is disposed so that an aperture ratio of the touch screen display apparatus may be enhanced. | 07-14-2011 |

20090153719 | Digital photographing apparatus and method of operating image pickup device - A digital photographing apparatus and a method of operating an image pickup device reduce generation of smear. The image pickup device includes a matrix of photoelectric converters which generate charges from incident light, vertical transfer paths for reading charges generated in the photoelectric converters and for transferring the read charges in a vertical direction, and a horizontal transfer path for transferring the charges on the vertical transfer paths in a horizontal direction. The method includes: applying vertical and horizontal transfer signals for causing the charges generated in photoelectric converters defining a subset of rows of the photoelectric converters to be read by the vertical transfer paths and to be transferred in the horizontal direction along the horizontal transfer path; and providing a predetermined period of time in which the horizontal transfer signals are not applied to the horizontal transfer path while charges are being transferred to the horizontal transfer path. | 06-18-2009 |
20090175511 | Digital photographing apparatus and method of controlling the same - A digital photographing apparatus is provided which can recognize a face even in a dark place, such as under a backlight condition, or in too bright a place, and also provided is a method of controlling the same. According to the method, when a face is not recognized, an exposure value is temporarily adjusted so as to generate an image signal, and a face recognition algorithm is performed from the image signal. | 07-09-2009 |
20090202178 | Digital image processing apparatus and method of arranging digital image files used by the same - A digital image processing apparatus capable of effective file management during the duplication and movement of a digital image file between digital image processing apparatuses, and a file arranging method used by the digital image processing apparatus. The apparatus stores a digital image file with a name including a serial number under a folder with a name including a part indicating a manufacturing company and a serial number. When the apparatus duplicates or moves a first digital image file stored in a first digital image processing apparatus to a second digital image processing apparatus, the digital image processing apparatus compares a name of a folder containing the first digital image file with a name of a folder of the second digital image processing apparatus, duplicates or moves the first digital image file to the folder, or generates a new folder and duplicates or moves the first digital image file to the new folder. | 08-13-2009 |
