Patent number: 6822632Abstract: Disclosed is a liquid crystal display device comprising a display part. The liquid crystal display device allows a common electrode voltage swinging depending on a gate off voltage of the display part to be fed-back through a feed-back circuit and to be held at a constant level, thus stabilizing the common electrode voltage and the gate off voltage coupled to a capacitance component, thereby preventing a picture displayed on the liquid crystal display panel from being divided into blocks. The common electrode voltage is detected at a position capable of being connected to the common electrode. The detected common electrode voltage is input into a comparator for outputting the common electrode voltage. The output of the comparator is controlled to thereby control the swing of the common electrode voltage.Type: GrantFiled: July 24, 2001Date of Patent: November 23, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Gyu-Su Lee, Jin-Ho Park, Yong-Eun Park, Nam-Soo Kang

Method and apparatus for driving a liquid crystal display by generating color-specific gray voltages
Publication number: 20040160402Abstract: The invention is an apparatus for driving a liquid crystal display. In the invention, the digital data signals for different pixels are converted to analog signals based on color-specific gray voltages. By providing color-specific gray voltages, the invention corrects any bias stemming from different electro-optical characteristics of different-colored pixels. In one embodiment, the invention includes a signal controller for generating digital data signals for different pixel colors and a gray voltage generator for generating gray voltage signals that are specific to the different pixel colors. A data driver, which is coupled to the gray voltage generator and the signal controller, converts each one of the digital signals to a corresponding analog signal by using one of the gray voltage signals that is associated with the same pixel color as the digital signal that is being converted.Type: ApplicationFiled: February 6, 2004Publication date: August 19, 2004Inventors: Sang-Soo Kim, Jheen-Hyeok Park, Seung-Hwan Moon, Gyu-Su Lee -
