[0102] figure 1 It is a block diagram showing the configuration of the liquid crystal display device 1 according to the first embodiment of the present invention. like figure 1 As shown, the liquid crystal display device 1 includes a liquid crystal display panel 10 , a gate driver 30 as a scanning signal line driver, a source driver 40 as a data signal line driver, and a display control circuit 50 as a display control unit.
[0103] In the liquid crystal display panel 10, m source lines SL1 to SLm serving as video signal lines, n gate lines GL1 to GLn serving as scanning signal lines, and these source lines SL1 to SLm and gate lines GL1 are formed. The intersections of -GLn correspond to (m×n) pixel forming sections 20 arranged in a matrix. Each pixel forming portion 20 includes a TFT 21 whose gate terminal as a control terminal is connected to a gate line GL passing through a corresponding intersection and whose source terminal as a first conduction terminal is...

[0138] The configuration and the figure 1 The configuration of the liquid crystal display device 1 of the first embodiment shown is the same, and therefore a block diagram and description thereof are omitted. The liquid crystal display device of this embodiment performs BC driving and high-speed scanning in the immediately following driving period when the number of pause frames in the pause period is more than the predetermined number, but when the number of pause frames in the pause period is less than the predetermined number, BC drive and high-speed scanning are performed. No scans are performed.

[0140] Figure 10 It is a block diagram showing the configuration of the correction circuit 102 included in the display control circuit of the liquid crystal display device of this embodiment. Figure 10 The correction circuit 102 is shown in the figure 2 The calibration circuit 101 shown further includes an idle frame number counting circuit 140 and a scanning s...
no. 3 Embodiment approach >
[0154] The configuration and the figure 1 The configuration of the liquid crystal display device of the first embodiment shown is the same, and therefore the block diagram and its description are omitted. When the image does not change from the idle period to the driving period, flicker is easily seen. Therefore, the liquid crystal display device of this embodiment performs BC driving and high-speed scanning in the immediately following driving period. However, flicker is not easily seen when the image changes, so neither BC drive nor high-speed scanning is performed.

[0156] Figure 13 It is a block diagram showing the configuration of the correction circuit 104 included in the display control circuit of the liquid crystal display device of the present embodiment. Figure 13 The correction circuit 104 is shown in the Figure 10 The illustrated correction circuit 102 is provided with an image comparison circuit 150 instead of the stop frame number counting circ...
