Abstract
The displaying screen is composed of basic displaying image element arranged from red, green and blue three basic colour displaying units according to a specific rule. organically combine the neighbouring image elements, in the row direction and column direction the semi image element is used as basic unit to recombine, then scanning, the large screen displayer with MXN resolution can be made to double density in both row and column directions and the resolution is changed into (2M)X(2N). Thus the resolution of the displayed image is improved. The neighbouring image element possesses of the overlapping property of semi image element, so the displayed image is relatively soft.
Description
The invention belongs to the scan method that a kind of color video shows.
The display screen of large colour video display is made up of numerous pixels.In each pixel, the red-green-blue picture dot is arranged in the rectangle of rule, is arranged in matrix by such pixel regularly by row, column again.Under the control of circuit, by lining by line scan or interleaved mode color image display information.Prior art is the three primary colors pixel that pictorial information that each is shown corresponds respectively to display screen.Since digitized picture show be with pixel as base unit, the possibility that does not exist the pictorial information between adjacent two pixels to show is so show that on large display screen digitized picture often seems soft inadequately.The density of display screen display element has determined the resolution of displayed image in addition, and the resolution that increase displayed image only reduces the physical dimension of pixel, correspondingly increases the density of display screen display element.
The purpose of this invention is to provide a kind of color video and show doubly close scan method, can increase the resolution and the soft property of displayed image.
The present invention organically combines neighboring pixels, after being expert at, recombinating as base unit with half pixel respectively on the column direction, scanning again, can make to have M * large screen display of N resolution all encrypts one times on ranks two directions, make the resolution of whole screen reach (2M) * (2N), increase the row, column number that shows like this, therefore increased the transient copy amount, thereby reached the effect of the resolution that improves displayed image.Adjacent image point has the overlapping character of pixel half, so the image that shows is comparatively soft.The display screen that the present invention relates to is meant by discrete red-green-blue display unit by certain regularly arranged basic display pixel of forming, and the display screen of being made up of this basic display pixel.
The technical solution used in the present invention such as Fig. 1, Fig. 2, shown in Figure 3.Fig. 1 is the Pareto diagram of display screen pixel, and r, g, b represent the red, green, blue picture dot respectively among the figure; Prior art is that pixel is regarded as unalterable isolated demonstration base unit, and shown in Fig. 2-1, promptly full frame pixel is (r, g, g, b).The present invention then reconfigures adjacent r, g, the b picture dot of forming pixel, and display screen is regarded as Fig. 2-1, Fig. 2-2, the basic pixel of Fig. 2-3, Fig. 2-4 four classes are expert at, column direction is formed with half pixel overlaid respectively.During scanning as shown in Figure 3, when choosing the odd-numbered line odd column, employing be the pixel (rggb) of Fig. 2-1; When choosing the odd-numbered line even column, employing be the pixel (grbg) of Fig. 2-2; When choosing the even number line odd column, employing be the pixel (gbrg) of Fig. 2-3; When choosing the even number line even column, employing be the pixel (bggr) of Fig. 2-4.For the display screen of the capable M row of N, the present invention has carried out the capable scanning of 2N, send 2M columns certificate simultaneously like this, and the display message amount is 2M * 2N, is equivalent to improve display resolution.
Below in conjunction with drawings and Examples the present invention is specified.
Fig. 4 is a schematic diagram of the present invention, and among the figure: 1 is line driver, and 2 are row or door, and 3 is row driver, and 4 are row or door, and 5 are the line scanning pulse generator, and 6 is visual odd column data latches, and 7 is the even column data latches, p
i, p
I+1Be odd-numbered line control signal, q
i, q
I+1Be the even number line control signal, x is the odd column reset signal, and y is the even column reset signal.
Embodiment: in the display element of being made up of the red-green-blue display element, each pixel is by a red picture dot r, two green picture dot g and g ', and a blue picture dot b forms.For odd line interlace, display element is r, g ' and g, b, be designated as (rg ' gb) pixel; For even number line scanning, display element is g, b and r, g ', be designated as (gbrg ') pixel.
Display screen is carrying out every field scan, and its odd field only shows odd column information, and its even field only shows even column information, field frequency is doubled to guarantee to show do not glimmer again.
During i odd-numbered line information of displayed image, by the p of line scanning pulse generator 5 outputs
iSignal is effective, and at this moment by row or door 2 gatings i odd-numbered line, i the odd-numbered line that drives displayed image by line driver 1 owns the information of (rg ' gb) pixel then; During i even number line information of displayed image, by the q of line scanning pulse generator 5 outputs
iSignal is effective, at this moment by row or door 2 gatings i even number line, drives by line driver 1 then, and i even number line of displayed image owns the information of (gbrg ') pixel.The rest may be inferred in line scanning, by the p of line scanning pulse generator 5 outputs
I+1, q
I+1Effective successively, scan all row successively.
Columns is according to also being divided into two groups of strange, even row.For the odd-numbered line odd column, display element is r, g ' and g, b, be designated as (rg ' gb) pixel; For the odd-numbered line even column, display element is g ', r and b, g, be designated as (g ' rbg) pixel.For the even number line odd column, display element is g, b and r, g ', be designated as (gbrg ') pixel; For the even number line even column, display element is b, g and g ', r, be designated as (bgg ' r) pixel.
When odd field showed, at first, during by gating, the odd column data of this odd-numbered line were admitted to visual odd column data latches 6, meanwhile provide even column reset signal y, remove visual even column data latches 7 in a certain odd-numbered line.At this moment to come gating by row or door 4 be the row of base unit with (rg ' gb) pixel to display screen, and drive by row driver 3, and display screen is that base unit shows this row information with (rg ' gb) pixel.In thereafter even number line during by gating, the odd column data of this even number line are admitted to visual odd column data latches 6, at this moment to come gating by row or door 4 be the row of base unit with (gbrg ') pixel to display screen, and drive by row driver 3, this moment, display screen was that base unit shows this row information with (gbrg ') pixel.
When even field showed, at first, during by gating, the even column data of this odd-numbered line were admitted to visual even column data latches 7, meanwhile provide odd column reset signal x, remove visual odd column data latches 6 in a certain odd-numbered line.At this moment to come gating by row or door 4 be the row of base unit with (g ' rbg) pixel to display screen, and drive by row driver 3, and display screen is that base unit shows this row information with (g ' rgb) pixel.In thereafter even number line during by gating, the even column data of this even number line are admitted to visual even column data latches 7, at this moment to come gating by row or door 4 be the row of base unit with (bgg ' r) pixel to display screen, and drive by row driver 3, this moment, display screen was that base unit shows this row information with (bgg ' r) pixel.
Adopt the shown image of display of this scan method, scanning density is than the scanning of adopting prior art The display of method doubles, and it not only can make the resolution ratio that shows image be improved, and makes image more Soft, be highly suitable for the large flat display screen of high brightness.
