Display device and driving method thereof

A display device includes: a display panel configured to display an image; a gate driver configured to provide a gate signal to the display panel; a timing controller configured to control the gate driver; and a memory controlled by the timing controller. The timing controller performs masking such that the gate signal is not output when a resolution of an input image is changed to a second resolution lower than the first resolution, and the timing controller has a resolution change period for calculating a driving compensation value required to display an image at the second resolution. 一种显示装置包括：显示面板，其被配置成显示图像；栅极驱动器，其被配置成向所述显示面板提供栅极信号；定时控制器，其被配置成控制所述栅极驱动器；以及存储器，其由所述定时控制器控制。当输入图像的分辨率被改变为低于第一分辨率的第二分辨率时，所述定时控制器执行掩蔽，使得不输出所述栅极信号，并且所述定时控制器具有分辨率改变时段，以用于计算以所述第二分辨率显示图像所需的驱动补偿值。
