1. A display device comprising:
a display portion including a plurality of source signal lines, a plurality of gate signal lines, and a plurality of pixel electrodes, each pixel electrode being connected to one of the plurality of source signal lines and one of the plurality of gate signal lines, the display portion being configured to display a frame image in a frame frequency for every vertical synchronizing signal, the frame image being represented by image signals corresponding to pixel electrodes; a source driver configured to apply voltages to pixel electrodes corresponding to the image signals via the plurality of source signal lines; a gate driver configured to scan the plurality of gate signal lines by outputting a gate signal to each of the plurality of gate signal lines; and a controller configured to control the source driver and the gate driver based on a control mode for displaying the frame image on the display portion, the control mode including a basic control mode and a low frequency control mode, in the basic control mode the frame frequency being determined to be a first frame frequency F1, and the low frequency control mode the frame frequency being determined to be a second frame frequency F2 (F2<F1), wherein: the controller is configured to control the gate driver such that a horizontal scanning period (H) is constant regardless of the control mode being the basic control mode or the low frequency control mode, in the basic control mode, the controller is configured to display the frame image on the display portion by causing the gate driver to progressively scan the plurality of gate signal lines, in the low frequency control mode, the controller is configured to determine whether a regional signal is on in a specific region corresponding to specific gate signal lines in a frame image, when it is determined that the regional signal is off, the controller is configured to display a sub-frame image on the display portion by causing the gate driver to perform interlaced scanning of the plurality of gate signal lines every K lines in the first frame frequency F1, where K is an integer expressed by F1/F2, and the controller is configured to display the frame image constituted by K sub-frame images on the display portion by repeating display of the sub-frame image for K times, when it is determined that the regional signal is on, the controller is configured to cause the gate driver to progressively scan the specific gate signal lines every time the sub-frame image is displayed. |
