DISPLAY DEVICE, DRIVING METHOD THEREOF, AND PORTABLE INFORMATION APPARATUS

Disclosed are a display device and a driving method thereof, and a portable information apparatus. A reference compensation voltage for compensating for a node voltage of each pixel for an image holding period after a refresh period for which image data is input in a low-speed driving mode is set. Then, the node voltage of each sub-pixel is compensated for using a corresponding reference compensation voltage on at least one frame basis at each start time and each end time of the image holding period, thereby preventing low image quality and reducing power consumption. 公开了一种显示装置及其驱动方法以及便携式信息设备。设置用于在低速驱动模式下、在输入图像数据的刷新时段之后的图像保持时段中补偿每个像素的节点电压的参考补偿电压。然后，在图像保持时段的每个起始时间和每个结束时间处，在至少一帧的基础上使用相应的参考补偿电压来补偿每个子像素的节点电压，从而防止低图像质量并降低功耗。
