Abstract

A display device includes gate lines, data lines, storage electrode lines and pixels. Each pixel includes a switching element connected to a gate line and a data line, a liquid crystal capacitor connected to the switching element and a common voltage, and a storage capacitor connected to the switching element and a storage electrode line. Signal generating circuits of the display generate storage signals based on gate signals in such a way that the storage signal applied to each pixel has a changed voltage level immediately after the completion of the charging of the data voltage into the liquid crystal capacitor and the storage capacitor. This enables the pixel electrode to reach the target voltage in a single frame, reduces the power consumption of the display, and improves its response time, reliability and durability.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2006-0016270 filed on February 20, 2006, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to display devices, such as liquid crystal displays (LCDs). Background technique [0004] Generally, an LCD includes two display panels having pixel electrodes and common electrodes and a layer of liquid crystal material having dielectric anisotropy interposed therebetween. The pixel electrodes are arranged in a matrix and connected to switching devices, such as thin film transistors (TFTs), which sequentially apply data voltages to the pixel electrodes row by row. The common electrode is disposed on the entire surface of the display panel and has a common voltage applied thereto. The pixel electrode, the common electrode, and the liquid crystal layer interposed therebetween constitute ...
