Description

Method, device and television set for 3D image display

Technical field

The present invention relates to the field of display technologies, and in particular, to a method, a device, and a television set for displaying a 3D image. Background technique

FIG. 1 is a schematic diagram of the implementation of the shutter type 3D display technology. Referring to FIG. 1, in the shutter type 3D display technology, the left and right eye images are alternately displayed, specifically, when the right eye image needs to be displayed, the right lens is turned on. When the lens is closed, when the left eye image needs to be displayed, the left lens is opened and the right lens is closed, and during the whole process, the refresh timing of the left and right eye images is kept synchronized with the switching timing of the left and right lenses of the glasses, so that the left eye of the person can pass. The left lens of the 3D glasses sees the left eye image of each frame of image, and the right eye of the 3D glasses can see the right eye image of each frame image through the right lens of the 3D glasses, and the user then processes the brain to form a 3D image.

Since the liquid crystal display has a retention characteristic, the retention characteristic means that the image display line on the liquid crystal screen after the image refresh is completed is kept in the refreshed image until the next image refreshes, and the image is converted into the next image display. . In the prior art, the shutter type 3D display technology alternately and continuously refreshes the left eye and the right eye image in the process of realizing the 3D display, and adopts the top of the display screen during the process of displaying the left (right) eye image. The last line of the first line of the bottom line is refreshed line by line. After refreshing a left (right) image, the next right (left) image is sequentially refreshed. Thus, when the right (left) eye image is displayed, the top line of the display begins to refresh the right (left) eye image, while the middle and low end of the display are still in the previous field, the left (right) image is displayed. The left (right) eye image and the next right (left) eye image will exist on the screen at the same time. At this time, when the right (left) eye lens is opened in the corresponding 3D glasses, the right (left) eye is made. Not only can you see the right (left) eye image, but you can also see the left (right) image of the screen. Leave the image. In this way, the left eye image shows that the right eye image remains, the right eye image shows that the left eye image remains, and the left eye and the right eye image crosstalk is generated during the 3D image formation process, and the 3D image is effective.

;3⁄4.

In order to solve the above-mentioned left and right eye image crosstalk problem, the following methods are used in the prior art to solve:

The LCD screen is used to insert the black field image 3D display technology. FIG. 2 is a 3D display timing chart of the black screen image inserted into the LCD screen. As shown in FIG. 2, in the process of displaying a 3D image, the left eye image and the black field are respectively displayed on the display screen. The image, the right eye image, and the black field image, then the 3D glasses are alternately turned on and off with the left and right eye images, gp: When the left eye image and the black field image are displayed on the display, the left eye lens of the 3D glasses is turned on, and the right eye lens is turned off. When the right eye image and the black field image are displayed on the display, the left eye lens of the 3D glasses is closed, and the right eye lens is turned on. Since the black and white images are alternately displayed in the left and right eye images, the residual image between the left eye and the right eye is reduced. Direct overlap on one image reduces crosstalk between left and right eyes.

However, in the process of implementing the technical solution in the embodiment of the present application, the inventors have found that the above shutter type 3D display technology has at least the following disadvantages:

1. Since half of the black field image is inserted into the display image, the display time of the left and right eye images constituting the 3D image is halved, and the content displayed in the other half is a black field image. In this way, the display brightness of the 3D display image is lowered, so that the shutter type 3D display technology itself has the disadvantage of low brightness, further aggravating the brightness of the shutter type 3D display, and the 3D display image is inferior.

2. Referring to FIG. 2, when the left and right eye images are alternately displayed with the black field image, when the black field image is displayed, the line bottom line refresh is completed from the top end, and after a black field image is refreshed, the next step is continued. Field right (left) image of. Since the liquid crystal molecules of the liquid crystal screen have a certain response time, especially the liquid crystal screen with a slow response speed of the liquid crystal, when the black field image is completely refreshed, the top line of the liquid crystal screen is refreshed first, and the black field image is stable, and the low end line is In the process of converting the left (right) eye image to the black field image, the steady state is not reached, the low end The line will have the left (right) eye image remaining. At this point, the next right (left) image will be refreshed from the top line of the LCD screen, so that the top of the LCD screen is refreshed to the next right (left) image. The low-end line will have the left (right) eye image of the previous field. Therefore, when the 3D receives the next right (left) image, the low-end line has the residual of the left (right) eye image of the previous field, BP : 3D image crosstalk. As can be seen from the above, the conventional use of a liquid crystal panel to insert a black field image to solve the crosstalk 3D display technology brings about a problem that the 3D image has low brightness and the effect of solving crosstalk is not good. Summary of the invention

The present invention provides a method and device for displaying a 3D image, and a television set, which solves the problem that a conventional 3D display technology is used to insert a black field image to solve a crosstalk 3D display technology, which causes a low brightness of a 3D image and a poor effect of solving crosstalk.

In order to further explain the technical means and functions of the present invention for achieving the intended purpose of the present invention, the specific embodiment and structure of the 3D image display method, device and television set according to the present application will be described below with reference to the accompanying drawings and preferred embodiments. , characteristics and their effects, detailed description as follows:

The foregoing and other technical aspects, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. The technical means and functions of the present invention for achieving the intended purpose can be more deeply and specifically understood by the description of the specific embodiments. However, the drawings are provided for reference and description only, and are not intended to be used for the present invention. limit.

The technical solution in the embodiment of the present application is to solve the above technical problem. The general idea is as follows: On the one hand, the technical solution of the present invention is to receive a frame of a 3D image and display it as four fields, wherein when displaying the first field of the left eye image, quickly within 1 \ cycle to refresh the display image, then the display period ^, holding left-eye image, the black image displaying the second field, quickly refresh the display image in the black-butyl ₂ cycles, then displays In the period 1 ₂ , the black field image is maintained. Similarly, when the third field right eye image is displayed, the display image is refreshed quickly in the ₃ cycles, and then the right eye image is maintained in the display period 1 ₃ . The fourth field black field image is displayed, and the display of the black field image is quickly completed in D ₄ cycles, and then the black field image is maintained during the display period t ₄ . When the second (four) field black field is displayed, after the refresh and hold is completed, the next right (left) eye image continues to be displayed, and the low-end line refresh is started from the top line of the display, so that during the refresh process The refresh line is completed first at the top line, and the black field image of the previous field is still maintained at the top line. Compared with the prior art, the technique of the present invention improves the refresh rate, and after the refresh is completed quickly, the right (left) is displayed. The eye image remains on the display, so the black field image is relatively reduced on the display during the display of the right (left) eye image, and because the inserted black field image reduces the brightness of the 3D image, then the black is reduced. The field image holds the time on the right (left) eye image, which increases the brightness of the 3D image.

On the other hand, the present invention adopts the above technical solution, and after displaying the left (right) eye image, after the refresh and hold is completed, the next black field image is continuously displayed, so that during the process of refreshing the black field image, at the top The line completes the refresh first, and the low-end line also maintains the left (right) eye image of the previous field. Compared with the prior art, the technology of the present invention improves the refresh rate and completes the refresh quickly. After that, the black field image will be maintained thereafter, and the low-end liquid crystal molecules are deflected from the left (right) eye image state of the previous field to the black field image state during the period of maintaining the black field image, and the black field image is maintained. After continuing to display the right (left) eye image, the low-end unrefreshed line is closer to the black-field image, reducing the left (right) eye image of the previous field of the low-end insufficiently deflected line, thus further reducing the 3D image Crosstalk.

In another aspect, it should be noted that those skilled in the art can know that the prior art of the shutter type 3D display is that the left eye and the right eye image are alternately displayed, and the left and right eye lens switches of the 3D glasses are used to receive the corresponding left eye image and the right time. The eye image, which forms a 3D effect in the human brain, displays the image process in the same way as a normal 2D display. That is, after the display image refreshes one frame image line by line or interlaced, the next image is sequentially refreshed immediately. The technical solution of the present invention breaks through the prior art method, and based on the black field image technology inserted between the left and right eye image displays, the refresh speed of the display image is improved, and after the fast refresh is completed, the display image is kept for a period of time, which can be further optimized and solved. The effect of crosstalk can also improve the brightness of 3D images.
