Wherein a kind of synoptic diagram of display timing generator has been shown among Fig. 5,, each run location (A shown in Fig. 5, B, C, D) constantly has been shown among Fig. 5 for the direction of motion of each pixel of expressing dot matrix display screen intuitively.
Subsequently, in concrete movement display process:
At t constantly; Each pixel of dot matrix display screen moves to the position in the upper left corner of pixel grid; After detecting this movement position, confirming corresponding with this movement position is the little picture that is merged into by image 1A, 2A, 3A, 4A, thereby will export demonstration by the little picture that image 1A, 2A, 3A, 4A are merged into; T display effect synoptic diagram constantly has been shown, then the move right distance of L/2 of each pixel of dot matrix display screen among Fig. 6;
At 2t constantly; Each pixel of dot matrix display screen moves to the position in the upper right corner of pixel grid; After detecting this movement position, confirming corresponding with this movement position is the little picture that is merged into by image 1B, 2B, 3B, 4B, thereby will export demonstration by the little picture that image 1B, 2B, 3B, 4B are merged into; 2t display effect synoptic diagram constantly has been shown among Fig. 7, and each pixel of dot matrix display screen moves down the distance of L/2 then;
At 3t constantly; Each pixel of dot matrix display screen moves to the position in the lower right corner of pixel grid; After detecting this movement position, confirming corresponding with this movement position is the little picture that is merged into by image 1D, 2D, 3D, 4D, thereby will export demonstration by the little picture that image 1D, 2D, 3D, 4D are merged into; 3t display effect synoptic diagram constantly has been shown among Fig. 8, and each pixel of dot matrix display screen is moved to the left the distance of L/2 then;
At 4t constantly; Each pixel of dot matrix display screen moves to the position in the lower left corner of pixel grid; After detecting this movement position; Confirming corresponding with this movement position is the little picture that is merged into by image 1C, 2C, 3C, 4C, thereby will export demonstration by the little picture that image 1C, 2C, 3C, 4C are merged into, and the display effect synoptic diagram in the 4t moment has been shown among Fig. 9.
All carrying out such periodicity for every pair picture to be shown, each pixel of dot matrix display screen shows; Because the demonstration time of each little picture is less than the retentivity time of eye of human eye; Because the visual persistence effect of human eye; Will form every original pixel at last and be divided into the display effect that 4 subpixels, each sub-pixel show each pixel after the fractionation respectively; Be about to resolution and improved 4 times, the synoptic diagram of the last viewing effect that forms of the above-mentioned display effect of foundation is shown in the fractionation synoptic diagram of Fig. 4.In addition, in the process of this division display, because the light number of the pixel when not changing the little picture that is combined and showing, thereby the brightness not only can not reduce dot matrix display screen and show the time, and the sharpness can improve dot matrix display screen and show the time.
In practical operation, because each pixel motion excessive velocities of dot matrix display screen, and the loss that each pixel of dot matrix display screen carries out moving at the right angle is bigger; During actual motion, the mode that can be similar to arc moves, to reduce loss; Thereby when final the demonstration, each pixel may demonstrate the display effect that is similar to camber line even annular, under the above-mentioned situation that each pixel is divided into 2*2; Concrete movement locus is similar to circular motion, and is shown in figure 10, do not repeat them here.
Need to prove; In above-mentioned explanation; For the purpose of simplifying the description, be that 2*2 the little image that has 2*2 pixel, the image to be displayed that each pixel is corresponding to be split as equal size with dot matrix display screen is that example describes, i.e. M=N=2; This explanation is not in order to limit the present invention program; According to actual needs, multiple fractionation mode and corresponding mode of motion can be arranged, the value of M, N is done different settings; For example that each pixel is corresponding image to be displayed is split as 1*2 (1 row, 2 row), 2*1 (2 row, 1 row), 2*3 (2 row, 3 row), 3*2 (3 row, 2 row), 3*3 (3 row, 3 row), 3*4 (3 row, 4 row) or the like, if pixel can be contained in the pixel grid after splitting according to this same mode the space, and can in a cycle period, occur once in each space.
Every pixel is being divided into 1*2 subpixels (1 row, 2 row), at this moment, the rectilinear motion about each pixel only need be carried out.If every pixel is divided into 2*1 subpixels (2 row, 1 row), at this moment, each pixel only need be carried out rectilinear motion up and down, all can not have the situation of arc.
Under the situation of the sub-pixel that a pixel is divided into more umbers, for example 2*3 (2 row 3 row), 3*2 (3 row, 2 row), 3*3 (3 row, 3 row), 3*4 (3 row, 4 row) or the like, the movement locus of pixel can be the capable track of S; For example move by row, from left to right in the first row motion, it is right certainly to left movement to move to second row more earlier; Moving to the third line again moves or the like from left to right; Perhaps, from top to bottom in the first row motion, move to secondary series again and move from bottom to top earlier by the row motion; Move to the motion or the like from top to bottom of the 3rd row again, specifically do not repeat them here.
Each pixel of dot matrix display screen is when moving; Concrete direction of motion also can freely be set according to actual conditions; To be example in the above-mentioned concrete example description, the direction of motion of each pixel also can be under the upper right left side, correspondingly; Corresponding burst also can change to some extent, makes that the movement position of pixel can be corresponding with the little picture that will show.
In addition, the display mode according to present image display periods does not have flickering in order to want the underwriter to observe picture with the aid of pictures; The frame per second of image should promptly refresh 50 pictures p.s., so more than or equal to 50Hz; In the present invention program,, be example to be split as K little picture in order to reach the image frame per second identical with existing mode; Little picture and the switch speed between the little picture after then splitting should be greater than 50*K; Be each pixel of dot matrix display screen moves to next position from a position time should reach 1/ (50*K) second, specifically be divided in the scheme of 2*2 little image that switch speed should reach 1/ (50*4)=5 millisecond at the above-mentioned image to be displayed that each pixel is corresponding; Be in the above-mentioned display timing generator shown in Figure 5, the t=5 millisecond.At this moment, above-mentioned cycle period one by one is equivalent to the display cycle of an existing secondary picture, promptly 1/50 second.Certainly; According to actual needs, if less demanding to refresh rate, flickering, or would need the refresh rate of requirements at the higher level; The movement velocity of corresponding dot matrix display screen also can be done other setting; For example the refresh rate with picture doubles, and movement velocity t is reached 2.5 milliseconds or the like, will not add to give unnecessary details at this.
Method according to the raising dot matrix display screen resolution of the invention described above; The present invention also provides a kind of device that improves dot matrix display screen resolution; The structural representation of the device of the raising dot matrix display screen resolution of the present invention in the concrete example has been shown among Figure 11, and it includes:
