Problems solved by technology

[0007] The retardation film and other optical films do not separate the odd and even lines, so that when the odd and even lines display two frames of different pictures, there will inevitably be mutual influence due to optical characteristics, resulting in crosstalk, that is, "crosstalk", which is right One of the most lethal problems of 3D image quality
The reason for the crosstalk is very simple, that is, the separation of the left and right eye images is not thorough enough, resulting in the images that should have entered the left eye being seen by the right eye, and the images that should have entered the right eye are seen by the left eye, resulting in the existence of 3D images that the audience sees. Ghosting, crosstalk is called "ghosting" by industry insiders
[0008] To sum up, due to the two frames corresponding to the odd and even rows, due to the optical characteristics of some optical films, the separation will inevitably be incomplete, and then the phenomenon of "picture ghost" crosstalk will occur, which will greatly affect the user's viewing experience and comfort.

Embodiment 1

[0045] Embodiment 1: Application in 3D TV display device.

[0046] In the following, the display system with a refresh rate of 60Hz is increased to 120Hz as an example for illustration. Usually, the refresh rate of 60Hz means that the display module displays 60 frames of image images per second. The left-view frame of the 3D image is displayed on odd lines, and the right-view frame of the 3D image is displayed on even lines. figure 1 As shown, the left and right viewing frames are displayed synchronously. In the polarized 3D technology, the 3D processing module sends 60 frames of images per second. Each frame of this image is an odd and even row corresponding to two images, so that crosstalk will occur in synchronous display.

[0047] In this embodiment, the number of image frames sent to the display module is doubled, that is, 120 frames of images are displayed per second.

[0048] The odd and even rows are sent out 60 frames of images respectively. This process is to change...

Embodiment 2

[0050] Embodiment 2: Application in a dual-screen display device.

[0051] Comparing with the 3D display principle, two frames of images corresponding to the left and right eyes are displayed at the same time. Of course, the two frames of images can also come from different signal sources, so that two frames of different images and image frames of two different signal sources can be displayed in the display module at the same time. After the signal is processed, the odd and even lines are output at the same time, and the odd and even lines correspond to different signal source images, so the problem of crosstalk must also occur. The method for reducing screen crosstalk in the present invention is used for processing, and the odd and even line signals are output in time division, which can be effective Improve this issue.

Abstract

The invention provides a method for reducing frame crosstalk of a 3D television. The method comprises the following steps of: carrying out odd or even line separation on each video frame to expand each video frame into two video frames; increasing the refresh rate of a display system by over one time; and outputting the expanded video frame image. The synchronous display of a 3D two-frame image corresponding to the parity line is changed into asynchronous display, so that the crosstalk at the junction of the parity lines is effectively avoided, the thorough separation of an image signal optical path system transmitted by the parity line is realized, the 3D display effect is effectively improved, the 3D sense judgment of a user is enhanced and the comfortableness for watching is improved.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a method for reducing crosstalk of 3D images. technical background [0002] Polarized 3D technology is also called polarized 3D technology, which is Polarized 3D in English, and passive polarized glasses are used in conjunction with it. The image effect of polarized 3D technology is better than that of chromatic aberration, and the cost of system implementation is not high, and the cost of glasses is low, so the application prospect is promising. [0003] Polarized 3D uses the principle that light has a "vibration direction" to decompose the original image. First, the image is divided into two groups of vertically polarized light and horizontally polarized light, and then the left and right sides of the 3D glasses use polarized lenses with different polarization directions. , so that the left and right eyes of a person can receive two sets of pictures, and then synthesize a t...
