Description
Art
The method that the present invention relates to simultaneously show two non-interfering 2D images on a display screen.
Background technology
At present, in the various electronic products with display device such as mobile phone, panel computer, navigator, DPF, all desktop background figures, screen protection picture, screen locking picture or unblock picture are all single image or cartoon picture.Image content is the most single, for abundant content and has the pursuit that characteristic is personalized in order to meet people, and the present invention utilizes the method that the display characteristic of 3D display screen realizes showing two non-interfering 2D images at synchronization.
Summary of the invention
The application apparatus of the present invention is: with the equipment such as 3D mobile phone/3D panel computer/3D handheld game machine/3D navigator/3D DPF of slit electronic liquid crystal grating 3D screen.The displaying principle of slit electronic liquid crystal grating is according to parallax obstacle principle, utilize and be placed in the parallax barrier between backlight module and LCD, under stereoscopic display mode, it should when the image seen by left eye shows on liquid crystal display screen, opaque striped can block right eye；In like manner, it should when the image seen by right eye shows on liquid crystal display screen, opaque striped can block left eye, and the image causing right and left eyes to be caught produces small deviation, and the viewable pictures of left eye and right eye separately makes onlooker see 3D image through retina.Parallax obstacle principle is to use a switching Liquid Crystal screen, polarizing coating and high molecule liquid crystal layer, utilize liquid crystal layer and polarizing coating to produce vertical stripes that a series of direction is 90 °, these stripeds are wide tens microns, are the formation of vertical slice grid pattern by their light.
The range of application of the present invention is；Desktop background figure in described equipment, screen protection picture, screen locking picture and unblock picture.
Concrete implementation method of the present invention is described by the following step: (present invention is as a example by slit electronic liquid crystal 3D mobile phone screen)；
(1) activate liquid crystal grating, under static drive, be shown as equally spaced opaque striped；
(2) slit electronic liquid crystal grating 3D mobile phone displaying principle as it is shown in figure 1,
Fig. 1 show laterally viewing 3D mobile phone screen mode；
In Fig. 1, LCD and liquid crystal grating are cross section, and actual top view is as shown in Figure 2；
R in Fig. 1 and Fig. 2 represents right figure (B figure), and L represents Zuo Tu (A figure), and the line of right and left eyes is perpendicular to liquid crystal grating；
The image that in Fig. 1, left eye, right eye accept respectively is A figure, B figure, the when that left-eye/right-eye moving in the direction being parallel to grating, the image accepted respectively remains as A figure/B figure, so left eye can be referred to as left eye viewing area along the viewing area in the direction that is parallel to grating, in like manner, right eye is referred to as right eye viewing area along the viewing area in the direction being parallel to grating；
(3) mode changing laterally viewing 3D mobile phone screen is mode of longitudinally watching,
Fig. 3 show longitudinal viewing mode, and mobile phone plane and display are 45 degree of angles；The cross section of 3D mobile phone longitudinally viewing is as shown in Figure 4；
R in Fig. 3 and Fig. 4 represents right figure (B figure), and L represents Zuo Tu (A figure)；
In Fig. 3, face, R/L place is LCD, orange is liquid crystal grating, liquid crystal grating is parallel with LCD, and the line of right and left eyes is parallel to liquid crystal grating, now region residing for right and left eyes line or be the left eye viewing area in step (2), or it is the right eye viewing area in step (2), each viewing area of the most former left eye, existing right and left eyes all receives left-eye image, in like manner, each viewing area of former right eye, existing right and left eyes all receives eye image；
When eyes and screen normal are in different angle, can alternately watch right figure (B figure) or left figure (A figure), reach on a display screen, once show two purposes not interfereing with each other 2D image；
(4)
A figure and the generation type of B figure in step (2) and step (3) are described below: press the half of original image height, take two interrelated or images that are not mutually related (image is called A figure and B schemes), by the mode of line interlacing, it is parallel to grating row, it is staggered for the image of a full-height, as shown in Figure 5；
(5) closing liquid crystal grating after viewing, opaque striped disappears, does not affect 2D pattern.
Accompanying drawing explanation
Fig. 1 is the displaying principle figure of slit electronic liquid crystal grating.
Fig. 2 be slit electronic liquid crystal grating laterally watch top view.
Fig. 3 is the longitudinal direction viewing mode figure of slit electronic liquid crystal grating.
Fig. 4 is the longitudinal direction viewing cross-sectional view of slit electronic liquid crystal grating.
Fig. 5 is the graphical arrangement of the present invention.
Specific embodiments
Fig. 1 is the displaying principle figure of slit electronic liquid crystal grating.After liquid crystal grating is activated, it is shown as some equally spaced opaque stripeds, it should when the image seen by left eye shows on liquid crystal display screen, opaque striped can block right eye；In like manner, when the image should seen by right eye shows on liquid crystal display screen, opaque striped can block left eye, the image causing right and left eyes to be caught produces small deviation, i.e. correspond to two width and there is the image of parallax information, i.e. disparity map, when regarding extent within the specific limits when, the disparity map received just can be merged by the brain visual cortex of people, so that onlooker sees 3D stereoscopic image.Fig. 1 shows people's state when laterally viewing mobile phone screen, the right and left eyes line striped opaque with grating of people is vertical, when people moves along the direction being parallel to grating fringe when, right and left eyes moves along grating fringe direction simultaneously, the image that the region of left eye process is watched is just as, the image that i.e. left eye is seen is that A schemes (this left eye is referred to as left eye viewing area through region) all the time, the image that the region of right eye process is watched also is the same, and the image i.e. seen is that B schemes (this right eye is referred to as right eye viewing area through region) all the time；When the eyes of people and screen plane normal in different angle when, the right and left eyes of people is all the time it is seen that different images, and while left eye sees A figure, right eye is it is seen that B figure, and in like manner, when left eye it is seen that while B figure, right eye is it is seen that A figure.
Fig. 2 be slit electronic liquid crystal grating laterally watch top view, the equidistant opaque striped i.e. presented after liquid crystal grating activates.
Fig. 3 is the longitudinal direction viewing mode figure of slit electronic liquid crystal grating, and mobile phone plane and display are 45 degree of angles.R/L figure composition LCD plane, orange opaque striped composition liquid crystal grating.Fig. 3 laterally watches owing to view direction is different from shown in Fig. 1, and change longitudinal viewing into, now the eyes line of people is parallel with grating fringe, in i.e. Fig. 3, two, the left and right of people is in same viewing area, or it is the left eye viewing area of people in Fig. 1 or for the right eye viewing area of people in Fig. 1, i.e. two, left and right receives A figure the most simultaneously, or is simultaneously received B figure.When eyes and screen normal are in different angle, can alternately watch right figure (B figure) or left figure (A figure), reach on a display screen, once show two purposes not interfereing with each other 2D image.
Fig. 4 is the longitudinal direction viewing cross-sectional view of slit electronic liquid crystal grating, is also the equidistant opaque striped presented after liquid crystal grating activates, and difference is, Fig. 4 is longitudinally to watch top view, and Fig. 2 is laterally to watch top view.
Fig. 5 is the graphical arrangement of the present invention, is associated by two width or onrelevant image line is by being parallel to grating row orientation, arranges with line interlacing.
