20100149200 | DISPLAY, APPARATUS AND METHOD FOR DRIVING DISPLAY - An apparatus for driving a display panel includes a first memory which stores a frame image data, a second memory which stores overshooting information. The apparatus receives an image signal from an external system via a CPU interface process. The second memory stores a difference data between the frame image data and an overshooting data. The overshoot is then calculated from the difference data and the frame image data. The apparatus also includes a two-line memory which stores an image signal of an n-th frame in a line unit and an image signal of an n−1-th frame in another line. The two-line memory compares the consecutive two frame data, so that the apparatus extracts overshooting information from a look up table. | 06-17-2010 |
20100156864 | DRIVING DEVICE FOR DISPLAY AND DISPLAY USING THE SAME AND DRIVING METHOD OF THE DISPLAY - A driving device for a display and a display using same, and a driving method of the display are provided. The display includes a display panel on which an image is displayed, and at least one optical sensor (photodetector) to detect the intensity of ambient (external) light incident upon the display panel. An external-brightness detector outputs an external-brightness signal based on the intensity of external (ambient) light and a backlight brightness controller changes the brightness of the image displayed (or backlight) on the display panel according to the external-brightness signal. The driving device may be implemented on an integrated circuit adapted to be connected to external-light photodetectors of type 1 or of type 2. The driving device may be may be dynamically configured to generate the external-brightness signal by sensing a voltage level of the light detecting node in a first mode of operation and may be reconfigured to generate the external-brightness signal by sensing a current level of the light detecting node in a second mode. | 06-24-2010 |
20100181572 | THIN FILM TRANSISTOR ARRAY PANEL - A data line and an amorphous silicon pattern are formed on a substrate. The first electrode pattern is extended from the data line and overlaps an edge of the amorphous silicon pattern. The second electrode pattern is made of the same metal as the first electrode pattern and overlaps the edge of the amorphous silicon pattern at an opposite side of the first electrode pattern. Edges of the first and the second electrode patterns are sharply formed so that a tunneling effect easily occurs through the amorphous silicon pattern. An indium-tin-oxide pattern for a capacitor is formed at the end of the second electrode pattern. The capacitor is formed between the ITO pattern and a common electrode. | 07-22-2010 |
