Abstract
The invention provides a method and a device for image display and a television. A left eye image and a right eye image are respectively displayed continuously to two frames. The second frame image repeats content of the first frame image. A pair of three dimensional (3D) glasses provided is in a display cycle of the second frame image. A corresponding glass lens is opened so that the corresponding left eye image and the corresponding right eye image are received and 3D is achieved. Due to the fact that in a refresh cycle of the second frame image, the first frame image and the second frame image displayed in a display screen are the same image, namely, the left eye/right eye image retention are not existed in the left eye/right eye image, crosstalk of the left eye image and the right eye image is avoided and display effect of the 3D image is improved.
Description
Technical field
The present invention relates to the Display Technique field, particularly the method and apparatus, the television set that show of a kind of image.
Background technology
shutter 3D Display Technique realize principle such as Fig. 1, see also Fig. 1, in shutter 3D Display Technique, right and left eyes image Alternation Display, specifically, be: when needs show eye image, right eyeglass is opened left eyeglass and is closed, when needs show left-eye image, left eyeglass is opened right eyeglass and is closed, and in whole process, the sequential that refreshes of right and left eyes image keeps synchronizeing with the switching sequence of glasses left and right eyeglass, so just guarantor's left eye can be seen by the left eyeglass of 3D glasses the left-eye image of each two field picture, guarantor's right eye can be seen by the right eyeglass of 3D glasses the eye image of each two field picture, the user is the processing by brain again, form the 3D image.
due to shutter 3D Display Technique in prior art in realizing the process that 3D shows, left eye and eye image alternately and are continuously refreshed demonstration line by line, in showing that the left/right eye pattern is as process, employing last column from the first row on display screen top to the bottom refreshes line by line and shows or the first row from last column of display screen bottom to the top refreshes demonstration line by line, all can there be simultaneously the previous frame image on display screen, that is: right/left eye pattern picture, like this, corresponding 3D glasses are left/when the right eye eyeglass is opened, make left-eye/right-eye not only can see the left-eye/right-eye image, can also see the afterimage of display screen previous frame image, that is: namely: the right/left eye pattern is as residual, like this, left-eye image shows the residual eye image that has, eye image shows the residual left-eye image that has, produced crosstalking of left eye and eye image in the 3D rendering forming process, the 3D rendering weak effect.
For solving above-mentioned right and left eyes picture crosstalk problem, in prior art, the following dual mode of main employing solves:
one, adopt 240Hz liquid crystal display screen inserting black color image 3D Display Technique, in a frame 3D rendering procedure for displaying, show respectively left-eye image at display screen, black image, eye image and black image, then the 3D glasses coordinate the right and left eyes image to show alternately opening and closing, that is: when showing screen display left-eye image and black image, 3D glasses left eyeglass lens is opened, the right eye eyeglass is closed, when showing screen display eye image and black image, 3D glasses left eyeglass lens is closed, the right eye eyeglass is opened, due at right and left eyes image Alternation Display inserting black color image, avoided afterimage between left eye and right eye, having alleviated right and left eyes crosstalks.
Two, the 3D Display Technique that adopts 120Hz liquid crystal display screen backlight segment to control, this technology is usually independently controlled liquid crystal display screen 6 sections subregions backlight and is opened or close, when showing a two field picture, when a certain subregion of image refreshing, only with the backlight open of this subregion, the backlight of other subregions closed, that is: only can show the image of this subregion, other sectional image do not show, can avoid other sectional image residual, have alleviated right and left eyes yet and have crosstalked.
But in the process of inventor's technical scheme in realizing the embodiment of the present application, existent defect is as follows at least to find above-mentioned shutter 3D Display Technique:
One, the 3D Display Technique of inserting black color image, can better solve the right and left eyes picture crosstalk, but, insert the black image of half in image owing to showing, 3D shows that the display brightness of image reduces, make shutter 3D Display Technique itself have the low shortcoming of brightness, the brightness that further increases the weight of shutter 3D demonstration is lower, and 3D shows the image effect variation.
Two, the 3D Display Technique of liquid crystal display screen backlight segment control, it is residual that the segmented backlight control technology has alleviated the sectional image of closing backlight, solve to a certain extent cross-interference issue, but, still can exist parts of images residual in the backlight open subregion, still can there be part right and left eyes picture crosstalk phenomenon, and, closed most of subregion backlight, also made to show that image brightness to a certain degree reduces, 3D shows the image effect variation.And when the 3D Display Technique liquid crystal display screen that adopts segmented backlight to control was applied to the 2D demonstration, backlight control adopted the standard-sized sheet mode usually, and therefore, 3D shows that when showing from 2D, the backlight control mode is different, and system is complicated.
No matter solution right and left eyes picture crosstalk problem due to prior art shutter 3D Display Technique adopts inserting black color image 3D Display Technique, still adopts segmented backlight to control the 3D Display Technique, all exists 3D to show that image brightness reduces, the poor problem of display effect.
Summary of the invention
