Problems solved by technology

[0002] Nowadays, with the continuous development of 3D technology, various 3D images have entered our lives. When users want to get good 3D video effects, corresponding liquid crystal display devices are essential, but 3D film Source formats usually include left-right split format, top-bottom split format, interlaced format, alternate-column format and common 2D video format, which requires the user to judge the 3D source format by himself, and then manually set it, because the user is familiar with the corresponding liquid crystal display device The lack of the video format makes the user do not know how to set the correct video format. Even if he knows how to set it, it is likely that due to the lack of understanding of the video format, multiple settings are required, which will cause inconvenience to the user.

Embodiment 1

[0044] figure 2 It is an implementation flow chart of a driving method of a liquid crystal display device according to the present invention, and the method includes the steps:

[0045] B1: Extract an image frame in the video;

[0046] B2: Divide an extracted image frame directly into a left-eye image and a right-eye image according to different image arrangements; calculate the color data according to the color data of each group of pixels corresponding to the left-eye image and the right-eye image respectively Pixel difference value; according to the pixel difference value of each group of pixels, perform an accumulation operation to obtain the overall difference value corresponding to at least two of the left and right division format, the upper and lower division format, the interlaced format, and the alternate column format, that is, the first overall difference. at least two of the value K1, the second overall difference value K2, the third overall difference value K3,...

Embodiment 2

[0062] This embodiment is a modified solution based on Embodiment 1. The difference lies in that the color data is the gray scale of the pixel, and the pixel difference value is the difference between the two pixels at the corresponding positions on the left-eye image and the right-eye image. In contrast, the overall disparity value is the accumulation of the pixel disparity values ​​of all pixels on the left-eye image and the right-eye image.

[0063] As mentioned above, the calculation of the pixel difference value is obtained by performing the XOR algorithm on the three sub-pixels of the pixel. For example, the brightness levels of the red, green, and blue sub-pixels of a pixel on the left-eye image are (100, 200, 300) respectively, and The brightness levels of the three sub-pixels of the pixels at the corresponding positions on the right-eye image are (100, 200, 200) respectively, then XOR the two to obtain (0, 0, 1) respectively, then, the pixel difference value of the two...

Embodiment 3

[0067] Figure 7 It is a schematic diagram of a related structure of a liquid crystal display device of the present invention. Here, only a part of the structure closely related to the automatic detection function is listed, wherein the liquid crystal display device 10 includes an extraction unit 11 for extracting image frames from a video. , a splitting unit 12 for splitting an image frame into a left-eye image and a right-eye image, a similarity detection unit 13 for calculating the similarity of the left-eye image and the right-eye image, a control output corresponding to the similarity The film source format output unit 14 of the film source format control signal of the judgment result; the liquid crystal display device 10 uses the extracting unit 11 to extract image frames from the video, and divides the image frames into The left-eye image and the right-eye image, and then the similarity detection unit 13 calculates and compares the similarity between the left-eye image ...

Abstract

The invention discloses a liquid crystal display device and a drive method of the liquid crystal display device. The drive method of the liquid crystal display device comprises the following steps that firstly, an image frame is extracted from a video; secondly, the image frame is directly divided into a left-eye image and a right-eye image according to a plurality of image arraying modes; color data of the left-eye image are compared with color data of the right-eye image, and the similarity of the left-eye image and the right-eye image is worked out in terms of the different image arraying modes through comparison results; thirdly, the image arraying mode, namely, the image arraying mode of the image frame, corresponding to the maximum similarity is selected and serves as the 3D film source format of the video to drive the liquid crystal display device. By means of the liquid crystal display device and the drive method, users can conveniently enjoy the 3D video effect.

Description

technical field [0001] The present invention relates to the technical field of video processing, and more particularly, to a driving method of a liquid crystal display device and a liquid crystal display device. Background technique [0002] Nowadays, with the continuous development of 3D technology, all kinds of 3D images have come into our lives. When users want to get good 3D video effects, the corresponding liquid crystal display device is indispensable, but 3D images Source formats usually include left-right split format, top-bottom split format, interlaced format, column-by-column format and common 2D video format, which requires the user to judge the 3D source format by himself, and then set it manually. The lack of video formats makes users do not know how to set the correct video format. Even if they know how to set the video format, they may need to perform multiple settings due to their lack of understanding of the video format, which brings inconvenience to the u...
