Embodiment approach 1
[0044] First, a liquid crystal display device according to Embodiment 1 of the present invention will be described. figure 1 It is a block diagram showing the overall configuration of the liquid crystal display device according to Embodiment 1 of the present invention. figure 1 The illustrated liquid crystal display device includes a liquid crystal panel 1, a liquid crystal panel drive circuit 2, an LED (Light Emitting Diode: Light Emitting Diode) backlight 3, an LED backlight drive circuit 4, an area feature detection unit 5, an area luminance determination unit 6, a moving Quantity detection part 7 and area luminance time change control part 8.
[0045] Although not shown in the figure, the liquid crystal panel 1 includes a plurality of gate lines, a plurality of source lines, switching elements and a plurality of pixel cells. and the intersections of multiple gate lines are arranged in a matrix, and a row of pixels in the horizontal direction constitutes a scanning line....
Embodiment approach 2
[0123] Figure 15 It is a block diagram showing the detailed configuration of the area luminance temporal change control unit 8 in the liquid crystal display device according to the second embodiment. In addition, the overall structure of the liquid crystal display device according to Embodiment 2 is the same as figure 1 The illustrated liquid crystal display device is the same, so description thereof will be omitted. In addition, in Figure 15 in, right with figure 2 The same components of the illustrated area luminance temporal change control unit 8 are denoted by the same reference numerals, and description thereof will be omitted.
[0124] Figure 15 The shown area luminance time change control unit 8 counts the motion vectors in the divided area that cannot be detected by the movement amount detection unit 7 as undetectable movement when it is determined that the movement amount detected by the movement amount detection unit 7 is equal to or greater than a predeterm...
