Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
Referring to Figure 1, Fig. 1 is a kind of flow chart of the display methods of display device provided in an embodiment of the present invention, described
Display device includes the first display panel and the second display panel being stacked, the pixel of shown first display panel with it is described
The pixel of second display panel corresponds, orthographic projection of the pixel of the first display panel on second display panel with it is right
The pixel answered is overlapped, as shown in Figure 1, the display methods the following steps are included:
Step 101 obtains the first image and the second image to be shown, and the first image is positioned at the display device
The image that can be watched in viewing range, second image can be seen outside display device viewing range
Image.
The display device viewing range can be regarded as the orthographic projection on the first display panel (or second display panel)
Regional scope in the first display panel (or second display panel).It can be regarded as outside the display device viewing range
Orthographic projection on first display panel (or second display panel) is located at except the first display panel (or second display panel)
Regional scope.
First image can be regarded as the image seen in the first display panel front, and the second image can be regarded as aobvious first
Show the image that panel side is seen.Second image is peep-proof image.For user when the first display panel side is watched, head is opposite
First display panel moves a distance, due between upper layer and lower layer display screen there are gap, be not to be properly fit onto one
It rises, therefore can be appreciated that another piece image, i.e. peep-proof image from display panel in terms of the side of the first display panel.
Fixed image can be used in second image, can be appreciated that same piece image always when side is seen in this way.Second image
It can be determined according to the first image, for example, Image Scrambling Algorithm is used to the first image, such as Hilbert curve scramble,
First image scrambling is the second image by random number scramble scheduling algorithm, so that the diversity ratio of the first image and the second image is larger,
In this way when display panel is seen in side, it is seen that content can be larger with the first image difference, achieve the purpose that peep-proof.According to
When two images determine the first image, the second image can change with the variation of the first image.
Step 102 determines according to the first image and second image and is input to the of first display panel
One image data and the second image data for being input to second display panel.
The first image data and the second image data are determined according to the first image and the second image.Specifically, according to following
Expression formula determines the first image data and second image data:
Fore (u)=raw (u)；
Bear (u)=raw (u)/fore (u)；
Fore (i)=sid (i)/bear (i+M)；
Bear (i)=raw (i)/fore (i)；
Wherein, 1≤i < M, M≤u≤n, n are the number of pixels of predetermined sequence, and the predetermined sequence is row or column；
Fore (u) is the grayscale value of u-th of pixel of predetermined sequence described in first display panel；
Fore (i) is the grayscale value of the ith pixel of predetermined sequence described in first display panel；
Bear (i+M) is the grayscale value of the i-th+M pixels of predetermined sequence described in second display panel；

Raw (u) is the grayscale value of u-th of pixel of predetermined sequence described in the first image；
Raw (i) is the grayscale value of the ith pixel of predetermined sequence described in the first image；
Sid (i) is the grayscale value of the ith pixel of predetermined sequence described in second image.
As shown in Fig. 2, label 1 show the first display panel, label 2 show the second display panel.Shown in label 11
For position of human eye, in display screen (i.e. the first display panel) front, as long as position of human eye in the width of display screen, that is, in fact
In range shown in line arrow, human eye is it can be seen that two layers of display screen individual element corresponds to superimposed display image.Work as people
Eye has gone out this range, that is, the position that label 22 indicates, human eye has gone out the width of display screen, the first display surface at this time
Not instead of not correspondingly with the second display panel (shielding after i.e.), 1 column that have been staggered (can also be staggered more plate (screen before i.e.)
Column), as the dotted line arrows.Image seen by person is generated by the superposition of preceding screen and the oblique opposite pixel of rear screen at this time.When
When human eye continues to be moved to the left, this inclination will continue to expand.Therefore, head is moved to the image that different positions is seen,
The result that screen is superimposed with preceding screen again after moving to left or moving to right after can regarding as.
As shown in Fig. 2, human eye position is position shown in label 22, when screen is moved to the left a pixel after being equivalent to
The case where.First image data and described the are calculated by the first image (i.e. RawImage) and the second image (i.e. SideImage)
Detailed process is as follows for two image datas:
In the present embodiment, using every row as object (can also be with every column for decomposition object) be decomposed, capable is only between row
Vertical, that is to say, that the calculation of every row is the same.It is decomposed by taking the first row as an example below, other rows calculate step
Equally.On the right side of Fig. 3 shown in four row's rectangles, each row indicates one-row pixels, in which:
Assuming that every row has n pixel, number 1,2 ..., n.
The grayscale value of raw (j) expression upper j-th of the pixel of RawImage；
Fore (j) indicates the grayscale value of j-th of pixel in ForeImage (i.e. the first image data)；
Bear (j) indicates the grayscale value of j-th of pixel in BearImage (i.e. the second image data)；
The grayscale value of sid (j) expression upper j-th of the pixel of SideImage；J=1,2 ..., n.
The image superposition situation that human eye is seen in side is indicated according to arrow oblique in Fig. 3.As can be seen that ForeImage is most
The pixel fore (n) on the right is without corresponding pixel, therefore it is without calculating, and is determined by following formula (1):
Fore (n)=raw (n) (1)
Since image seen by person (i.e. display device show image) is the first image data and the second image data
Superposition as a result, the imaging results (i.e. the grayscale value of the pth row q column pixel of the first image) of i.e. pth row q column pixel are:
The product of the grayscale value of the grayscale value and the second image data pth row q column pixel of first image data pth row q column pixel,
Therefore, for the nth pixel on pth row, it can get following expressions:
Bear (n)=raw (n)/fore (n) (2)
Recursion is carried out until the pixel that number is 1 using expression to the left since the pixel of number n-1
It calculates:
Fore (i)=sid (i)/bear (i+1) (3)
Bear (i)=raw (i)/fore (i) (4)
Wherein, until the number of i is decremented to 1 since n-1.
The every a line for traversing RawImage and SideImage, can be obtained the first image data and the second image data.
The above-mentioned calculation to be moved to the left when a pixel, when being moved to the left M pixel, ForeImage is most right
The M pixel on side does not have corresponding pixel, at this point, the grayscale value method of determination of M pixel of ForeImage rightmost are as follows:
Fore (u)=raw (u)；Wherein, M≤u≤n；
Correspondingly, the grayscale value method of determination of second M pixel of display panel rightmost are as follows:
Bear (u)=raw (u)/fore (u)；
Since rear screen is moved to the left M pixel, then for 1≤i of serial number < M pixel, the first image data is determined
Mode are as follows:
Fore (i)=sid (i)/bear (i+M)；
Bear (i)=raw (i)/fore (i)；
The every a line for traversing RawImage and SideImage, can be obtained the first image data and the second image data.On
Stating process only needs once traverse to the first image and the second image, and speed is fast, and real-time is good.
Above-mentioned calculation corresponds to the case where human eye position is on the left of display panel, and human eye position is being shown
When on the right side of panel, calculation is same as described above, only need the number of pixel in a manner of turning left and be sequentially increased from the right side into
Row number.
When human eye moves up and down, it is contemplated that actual conditions:
(a) such as first face display screen, second need top or following the case where just meeting vertical shift in first, but this
The chance that position phenomenon occurs is smaller.
(b) first face display screen, second, can be by this Directional Decompositions at level in the oblique upper or obliquely downward of first for another example
Direction displacement and vertical direction displacement.Horizontal direction has had peep-proof function, overall even if the peep-proof function of vertical direction is not added
Upper is also that can achieve peep-proof function.
(c) the if desired peep-proof function of vertical direction can be traversed with every column to decompose object using aforesaid way
Each column of RawImage and SideImage, to obtain the first image data and the second image data.
Position of human eye and the corresponding relationship of the number of pixels of rear screen movement can be used under type such as and determine.As shown in figure 4, every
A pixel wide is denoted as w, Gao Jizuo h, and the distance between two layers of display screen is denoted as v, human eye in position A apart from rear screen image away from
From L is denoted as, horizontal distance when being moved to position B by position A is denoted as D, and human eye sees ForeImage's just at the B of position
Leftmost side pixel fore (1), and it is (2) adjacent pixel bear that this pixel is corresponding with BearImage, reaches peep-proof just at this time
Effect.The angle of position A, B and pixel bear (2) are θ.Moving distance D is calculated at this time, is obtained
D=L*tan (θ)；
Dotted arrow is by the end face center of fore (1) and the end face center of bear (2) in Fig. 4, therefore has
Tan (θ)=w/ (h+v)；
It can get by above-mentioned formula:
D=L*w/ (h+v)；
The screen distance that human eye moves to left when moving to left a pixel wide w after D expression, i.e., after to shield a mobile pixel corresponding anti-
Peep distance.It can similarly obtain, the corresponding peep-proof distance of M pixel of movement is D=L*M*w/ (h+v)
According to above-mentioned formula, it may be determined that the peep-proof distance after mobile M pixel, in this way, can be arranged for varying environment
Then peep-proof distance calculates according to peep-proof distance and needs mobile number of pixels, and then asked by the first image and the second image
Obtain preceding screen image (i.e. the first image data) and rear screen image (i.e. the second image data).
What previous step calculated is the case where human eye moves to left, and when human eye moves to right, screen moves right after being equivalent to.Due to preceding
Screen image has been upset afterwards, therefore the peep-proof image seen on right side also differs greatly with original image (i.e. the first image), can be with
Reach peep-proof effect.
In the present embodiment, by obtaining the first image and the second image to be shown, the first image is positioned at described
The image that can be watched in display device viewing range, second image are the institute outside display device viewing range
The image that can be seen；The first figure for being input to first display panel is determined according to the first image and second image
As data and the second image data for being input to second display panel, it may make user in the first display panel front in this way
The image seen is different from the image seen in the first display panel side, achievees the purpose that peep-proof, can also be according to the actual situation
Peep-proof range is adjusted flexibly, to meet user's different demands.
Optionally, during calculating the first image data of acquisition and the second image data, since calculating process is related to
To division, due to being related to division, divisor cannot be 0.When divisor is 0, to being reprocessed after divisor plus 1.Due to pixel gray level
The value range of value is 0~255, and decimal can be generated in above-mentioned calculating process, will lead to the growth or diminution of calculated result at double,
Cause data excessive or too small, therefore, it is necessary to be modified to calculated result.
The mode being modified to the first image data can are as follows:
If fore (i) > 255, the value for correcting fore (i) is β * sid (i)/bear (i+M)；
If fore (i) < 1, value 2*sid (i)/bear (i+M) of fore (i) is corrected；
Wherein, β=1/ (α+1), α=fore (i)/255.
Specifically, in the case where the rear mobile pixel of screen, need to be handled as follows when fore (i) > 255:
The amplification coefficient for calculating fore (i), is denoted as
α=fore (i)/255；
It can be obtained according to formula (3), reduce fore (i) and be equal to diminution sid (i), therefore obtain coefficient of reduction
β=1/ (α+1)；
Fore (i) is recalculated, is obtained:
Fore (i)=β * sid (i)/bear (i+1)；
Because fore (i) may be used as denominator, it is therefore necessary to guarantee that its value is greater than 0.As fore (i) < 1, meeting
Calculated result is caused to be doubled and redoubled, at this point, using following expression:
Fore (i)=2*sid (i)/bear (i+1)；
In the case where rear screen mobile M pixel, if fore (i) > 255, correct the value of fore (i) for β * sid (i)/
bear(i+M)；If fore (i) < 1, value 2*sid (i)/bear (i+M) of fore (i) is corrected.
The mode being modified to the second image data can are as follows:
If bear (i)<1 or bear (i)>255, the value for correcting fore (i) is r1, and the value of bear (i) is r2,
In, raw (i)=r1*r2,1 < r1≤255；1 < r2≤255.
Since the value of modification bear (i) is equivalent to the value of modification fore (i), it will lead to more changes in this way.Therefore work as
When bear (i)<1 or bear (i)>255, raw (i) is decomposed into the form (such as method of extraction of square root) that two numbers are multiplied, is made
Raw (i)=r1*r2, fore (i)=r1, bear (i)=r2；
That is, the value for correcting fore (i) is r1, and the value of bear (i) is r2 if bear (i)<1 or bear (i)>255,
The grayscale value of the pixel of other positions remains unchanged, and only correcting grayscale value is bear (i)<1 or the pixel of bear (i)>255.
