Abstract: A liquid crystal display (LCD) device are disclosed, which reduce power consumption and improve an image quality. The LCD device includes a liquid crystal panel in which a plurality of sub-pixels is defined by intersection of a plurality of gate lines and a plurality of data lines, and sub-pixels adjacent to each other in a column direction are connected by sharing the plurality of gate lines. A gate driver may sequentially transfer a scan pulse to even-numbered gate lines and then sequentially transferring a scan pulse to odd-numbered gate lines. A data driver may be synchronized with the applied scan pulse in providing data voltage to columns of sub-pixels. The data driver provides the data voltage having different polarities to a neighbor data line during one frame interval such that sub-pixels are driven by a horizontal 2-dot inversion scheme.

Abstract translation: 公开了一种液晶显示（LCD）装置及其驱动方法，其降低功耗并提高图像质量。 LCD装置包括液晶面板，其中多个子像素由多条栅极线和多条数据线的交点限定，并且在列方向上彼此相邻的子像素通过共享 多条栅线。 栅极驱动器可以顺序地将扫描脉冲传送到偶数编号的栅极线，然后顺序地将扫描脉冲传送到奇数编号的栅极线。 数据驱动器可以与所施加的扫描脉冲同步，以向子像素列提供数据电压。 数据驱动器在一个帧间隔期间向相邻数据线提供具有不同极性的数据电压，使得子像素由水平2点反转方案驱动。
