Embodiment approach 1
[0029] figure 1 A schematic configuration diagram showing a liquid crystal display device 1 according to Embodiment 1 of the present invention. figure 2 is built in figure 1 A block diagram of the FRC circuit 20 in the signal processing circuit 3 shown in . exist figure 1 Among them, a liquid crystal panel 2 (display unit) has a plurality of pixels 6 at intersections of scanning lines 8 and signal lines 7 arranged in a matrix. The pixel 6 is driven by a TFT not shown connected to the pixel, the scanning line 8 and the signal line 7 . In addition, the scanning lines 8 are driven by the scanning driving unit 9 and the signal lines 7 are respectively driven by the data driving unit 4 . In this embodiment, the above-mentioned scanning lines 8 and signal lines 7 are driven by a conventional line-sequential driving method, which is well known, so detailed description thereof will be omitted here.
[0030] In addition, the data drive unit 4 for driving the signal line 7 has ...
Embodiment approach 2
[0049] The schematic structure of the liquid crystal display device according to Embodiment 2 of the present invention is the same as that of Embodiment 1 above except for the liquid crystal panel, data driver, scan driver, and FRC circuit, and detailed description thereof will be omitted. Only the differences from Embodiment 1 will be described in detail below. Figure 4 It is a configuration diagram of the FRC processing circuit 20 in the second embodiment. exist Figure 4 Among them, the line memory 21 is a memory for storing the image data 30 of one line displayed on the liquid crystal panel 2 for subsequent signal processing. In addition, the liquid crystal panel 2 used in this embodiment is the same as the above-mentioned first embodiment, and in particular, 2-frame FRC processing is used in a high-gradation region where the luminance changes greatly depending on the viewing angle.
[0050] The FRC processing circuit 20 in Embodiment 2 is composed of a 2-frame FRC proc...
Embodiment approach 3
[0072] The schematic configuration of the liquid crystal display device according to Embodiment 3 of the present invention is the same as that of Embodiments 1 and 2 above except for the liquid crystal panel, data driver, scan driver, and FRC circuit, and detailed description thereof will be omitted. Hereinafter, only differences from Embodiment 1 will be described in detail. Figure 6 It is a configuration diagram of the FRC processing circuit 20 in the third embodiment. exist Figure 6 Among them, the line memory 21 is a memory for storing image data 30 of one line displayed on the liquid crystal panel 2 for subsequent signal processing.
[0073] The FRC processing circuit 20 in the present embodiment 3 is made up of 4 frames of FRC processing circuits 49, 7 frames of FRC processing circuits 83, and 2 groups of addition and subtraction circuits. The comparison circuit 28 adopts the grayscale (D 0 ~D 63 ) value, the output 57 of the above-mentioned 4-frame FRC processing c...
