Patent number: 7671855Abstract: Disclosed are an LCD capable of realizing a pre-charging method even in the random data-enable mode, and an apparatus and method for driving the same. In the LCD driving apparatus, a timing controller outputs a vertical sync start signal based on a data-enable signal having an irregular output interval to control the output of the image data. A gate driver sequentially applies both first and second gate-on voltages to a same gate line based on the vertical sync start signal. The first gate-on voltage is to drive a previous line being most adjacent to and having the same polarity as the current line, and the second gate-on voltage is to drive the current line. An LCD panel is first charged with the first gate-on voltage supplied from the gate driver, and then charged with the second gate-on voltage, so that it can display analog image data received from the data driver during the second charging.Type: GrantFiled: May 1, 2006Date of Patent: March 2, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Seung-Woo Lee, Man-Bok Cheon, Su-Hyun Kwon
