Abstract: In a liquid crystal display one pixel is divided into two subpixels, the two subpixels are connected to two subdata lines extending from one data line, and a desired data voltage is applied by using a data driving switching element connected to the subdata line, thereby reducing the number of data lines needed to reduce the cost of the driver and preventing a lack of space to mount the data driver while dividing one pixel into two subpixels and differently applying voltages of the two subpixels.
Abstract translation: 在液晶显示器中，一个像素被分成两个子像素，两个子像素连接到从一个数据线延伸的两个子数据线，并且通过使用连接到子数据线的数据驱动开关元件来施加期望的数据电压，从而减少 减少驱动器成本所需的数据线数量，并且防止在将一个像素分成两个子像素并且不同地施加两个子像素的电压时安装数据驱动器的空间不足。
