Embodiment approach 1

[0066] Figure 4 It is a block diagram showing the configuration of the image display device according to Embodiment 1 of the present invention.

[0067] exist Figure 4 Among them, the image display device 100 includes: an image processor 101 , a display panel control circuit 102 , a gate driver 103 , a source driver 104 , and a display panel 105 . The image processor 101 has an interpolation image signal generating unit 106 . In addition, the display panel 105 includes: a display area 107 as a display screen; N scanning lines 108-1, 108-2, . . . , 108-N; and M data lines 109-1, 109-2, .. ., 109-N.

[0068] In the image processor 101 as a signal processing unit, an interpolation image signal generation unit 106 performs interpolation image signal generation processing on sequentially input image signals. Arrow S1 indicates a signal line for inputting an image signal to the image processor 101 .

[0069] Here, refer to Figure 5 An example of interpolation image signal g...

Embodiment approach 2

[0105] Hereinafter, an image display device according to Embodiment 2 of the present invention will be described. The image display device of the present embodiment is structurally the same as the image display device 100 of the first embodiment. Therefore, when referring to the same structural elements as those described in Embodiment 1, the same reference numerals are used to denote the same structural elements, and a detailed description of the structural elements will be omitted.

[0106] This embodiment differs from Embodiment 1 in that when the interpolation image signal generation unit 106 generates the display data signal, it inserts the scanning of a part of the scanning lines used for displaying the original image into the scanning lines used for displaying the same original image. During the scanning of the scanning lines of other parts, the time interval of scanning of a part of the scanning line groups is made uniform.

Embodiment approach 3

[0127] Hereinafter, an image display device according to Embodiment 3 of the present invention will be described. The image display device of the present embodiment is structurally the same as the image display device 100 of the first embodiment. Therefore, when referring to the same structural elements as those described in Embodiment 1, the same reference numerals are used to denote the same structural elements, and a detailed description of the structural elements will be omitted.

[0128] This embodiment differs from Embodiment 1 in that interpolation image signal generating section 106 inserts a scan for displaying an interpolation image into a scan for displaying an original image of one frame when generating a display data signal. , so that the scanning time interval of a part of the scanning line group is uniform.

[0129] Figure 12 It is a figure for demonstrating an example of the scan driving operation|movement of this embodiment.

[0130] exist Figure 12 In t...

Abstract

Provided are an image display apparatus and an image display method in which the definition of a moving image can be increased. An image processor (101) generates an interpolation image signal from an input image signal. A display panel (105) has a display area (107) which successively displays an original image on the basis of the input image signal and an interpolation image on the basis of theinterpolation image signal. The display panel (105) indicates an image at a higher rate in a specific sectional area of the display area (107), for example, a lower area of the display area (107) than in other sectional areas of the display area (107).

Description

technical field [0001] The present invention relates to an image display device and an image display method. Background technique [0002] Active-type (active-type) liquid crystal display devices and active-type organic electroluminescence (EL) display devices such as hold-type (hold-type) display methods and CRT (cathode ray tube, cathode ray tube) display devices such as pulse-type Compared with the display method, it has the advantages of less flicker and less fatigue of the eyes. [0003] On the other hand, with regard to the moving image display of the hold type display method, it has been reported that the moving image is perceived as an image obtained by integrating the number of pixels fluctuating between frames, and the integration caused by the movement of the image results in the generation of an image blurring (for example, refer to Patent Document 1 and Patent Document 2). As the reason, it can be cited that due to human visual characteristics, light stimulati...
