Description
Technical field
The invention belongs to the image display technology field, relate to a kind of method that improves the LED display display effect, specifically a kind of pixel multiplexing improves the method for display screen image analytic degree.
Background technology
The basic display unit of digital picture is a pixel.The quality of picture quality mainly is subjected to two factor affecting, and the one, the physical attribute of image is a physical picture element density, represents with image resolution ratio or physical resolution; Another is a color attribute, for the color levels that single pixel can show, uses image figure place or gray level expressing.
The resolution in digital video image source commonly used is up to 1600 * 1200 (USXGA) at present, 1280 * 1024 (SXGA), 1024 * 768 (XGA), 800 * 600 (SVGA) and 640 * 480 (VGA) commonly used.The pixel in digital video image source is made up of the red, green, blue three primary colours.The image figure place is monochromatic 8, and three primary colours are 24 true color, and promptly Show Color is 2
8* 2
8* 2
8Look.We can say enough height, color is enough abundant.
LED display is as the digital picture display media, in real time the image information in display video image source.The key factor that influences the LED display display effect has 2 points: the one, and the physical resolution of LED display, i.e. pixel point density on the unit area; The 2nd, the Show Color of display screen and gray shade scale.Aspect Show Color and gray shade scale, the Show Color of LED display has reached 256 grades at present, and monochromatic gray level resolution is 10bit～16bit.On Show Color and gray level grade, LED display can satisfy the requirement as digital display terminal.By improving physical resolution, promptly pixel point density improves display efficiency and just becomes present hot technology in the industry on the unit area.But practical difficulty is arranged by pixel point density on the physical method increase unit area:
(1) the special-purpose Driving technique of present domestic immature, the high integrated micro LED of LED pipe high density electronics package technique is immature.Be subjected to the restriction of aspects such as LED pipe, electronic devices and components encapsulation physical size and heat radiation in addition, when pixel point density acquires a certain degree, dwindle pixel interval again, to improve pixel point density impossible.
(2) cost of LED display depends primarily on the quantity of LED pipe (core), and the cost of circuit part only accounts for the very fraction of display screen total cost.When display area one regularly will improve display effect, can only improve physical resolution, promptly dwindle pixel interval, increase the display quality that LED pipe quantity improves digital picture, and the increase of LED pipe quantity increases the cost of display screen greatly, market is difficult to accept.LED pipe (core) quantity increases, and current densities increasing, circuit complexity are increased; Failure rate is increased, and the display screen maintenance cost improves.
LED display basic composition unit is a pixel, and each pixel is made up of discrete red, green, blue luminotron.LED display generally has two kinds of arrangement modes: a kind of is to concentrate coagulation type, and a kind of is even distributing.
Shown in Fig. 1 (1), 1 (2), 1 (3), 1 (4), concentrate the coagulation type LED display to form pixel by discrete red, green, blue luminotron, it is regularly arranged that pixel is, and the geometric configuration of each color single tube quantity and arrangement position is different according to the design needs in each pixel.The red, green, blue luminotron is concentrated in each pixel, and colour mixture is good.
As Fig. 2 (1), 2 (2), 2 (3), shown in, evenly the LED display red, green, blue single tube of distributing arrangement is independent, and each single tube equidistantly evenly distributes, and the red, green, blue single tube is pressed certain geometrical rule and arranged, can form the red, green, blue pixel of dispersion, colour mixture is relatively poor.
The procedure for displaying of LED display is the mapping process of source video image to display screen.There are mapping relations in the pixel of display screen and the pixel of image source.The display image display mode is divided into real mapping and combination mapping.
Most of display screen on the market adopts the display mode of real mapping at present, and display screen is generally concentrates coagulation type to arrange.The corresponding real image element of real mapping, the image source pixel is corresponding one by one with pixels of display screen.Capable n is listed as if the LED display screen is m, and m * n pixel promptly arranged, and can reappear the image information of image source m * n pixel.
Fig. 3 is the circuit structure block diagram of real mapping.Computer graphic image source 7 view data send by data transmitter 8, are received and to send scan drive circuit 10 to drive the display screen luminotrons luminous by data sink 9.
Fig. 4 (1), 4 (2) is real mapping LED display scan drive circuit, and each pixel 1 has the row, column control line among the figure.Red, green, blue pipe common row control line 5 wherein; The row control line separates, and 2 is that red pipe row control line, 3 is that green pipe row control line, 4 is blue pipe row control lines.If same pixel has two same colour tubes, two with the shared row control line of colour tube, two shared row control lines 2 of red pipe among Fig. 4 (2).
Virtual display technique has solved the problem that shows more information at the little screen of trying one's best, with the display tube of trying one's best few to a certain extent.
Virtual display technique essence is according to the adjacent principle of vision signal, utilize the persistence of vision phenomenon of human eye, utilization image processing techniques and control technology, reach and improve display screen vision picture element density and image analytic degree, on the LED display of certain area, show the purpose of the display effect of more images information, lifting display screen.
The display screen of virtual technology adopts the display mode of combination mapping, and display screen is generally even distributing and arranges.As shown in Figure 5, on the line direction between per two adjacent real image vegetarian refreshments, also can be combined into pixel two red, green, an indigo plant on the column direction between per two adjacent real image vegetarian refreshments, except that marginal point, that every luminotron and on every side three LED pipes can constitute is two red, the packed-pixel point of one green a, indigo plant, four of objective formation " virtual image point " around every luminotron like this, as shown in Figure 6, these " virtual image is selected " are different with the real image vegetarian refreshments of real mapping, there is not relation one to one with the image source pixel, so be called " virtual pixel ".
The principle of virtual demonstration: cooperate control and turntable driving technology, divide the same position of four times contiguous four the pixel information of image source being delivered to the LED screen, make the fundamental point (single tube or pixel) of each moment display screen identical, and each data are inequality, distribute in each single tube four virtual representation vegetarian refreshments on every side, as shown in Figure 6.Four virtual representation vegetarian refreshments that four scanning forms are not overlapping, but because the persistence of vision characteristics of human eye build up a width of cloth picture in human eye.
If display screen real image vegetarian refreshments battle array is: m * n (m is a real image vegetarian refreshments line number, and n is a real image vegetarian refreshments columns), then the virtual pixel dot matrix is: (2m-1) * (2n-1); When m and n were enough big, the virtual representation vegetarian refreshments approximated 4m * 4n, i.e. 4mn is equivalent to four times of real image vegetarian refreshments, realizes the display effect of plain four times of real image.
Tradition realizes the virtual two kinds of methods that show: the one, and pixel time-division multiplex technology, the one, pixel decomposition technique.
The pixel time-division multiplex technology:
Two red on the display screen, one green, blue pixel is refreshed by the message loop of adjacent a plurality of pixels in the image source with time division multiplexing mode, and a plurality of pixels in the image source are with pixel on the shared display screen of time-multiplexed mode.Implementation method a: width of cloth picture is resolved into four different images constantly, promptly image source is resolved into four: odd-numbered line-odd column, odd-numbered line-even column, even number line-odd column, even number line-even column data, divide four scannings of timesharing constantly that four field data are delivered to display screen and show.With the red, green, blue pixel is unit, and adjacent 4 the three primary colours information data timesharing of image source is mapped on the corresponding red, green, blue luminotron of the same pixel of display screen.
Shortcoming: the effective visible sensation picture element density is constant, and the pixel granular sensation is obvious, and the span of a pixel is arranged; Timesharing scanning increases volume of transmitted data, compares transmission bandwidth with real mapping display mode and widens; Sweep speed increases, to the reaction velocity index request height of device; Timesharing scanning makes the design of drive circuit complexity, shows the control procedure complexity; Rely on fast scan imaging, pixel is a virtual image point, is showing that digital ratio the unclear phenomenon of writing can occur when drawing literal.
The pixel decomposition technique:
Display screen red, green, blue pipe is a single tube independent of each other, is not a pixel with red, green, blue.Each single tube is with the corresponding primary colours information of the some neighbors in time-multiplexed mode reproduced image source.Each LED single tube equidistantly evenly distributes, and each single tube is controlled separately.Implementation method: for each single tube on the display screen in time-multiplexed mode, the corresponding primary colours information of adjacent four pixels of scan round image source.
Shortcoming: the LED single tube equidistantly evenly distributes, and when forming red, green, blue three primary colours pixel, presents maximum discrete state between tricolor pipe, and the colour mixture effect is relatively poor; Timesharing scanning increases volume of transmitted data, compares data transfer bandwidth with real mapping display mode and widens, and sweep speed increases; Each luminotron of display screen is controlled separately, splits row control, and the display screen line scan drive circuit is doubled, and hardware cost increases, and the circuit complexity increases; Fast scan imaging, pixel are virtual image point, are showing that digital ratio the unclear phenomenon of writing can occur when drawing literal; Can not select real mapping display mode and virtual pixel display mode flexibly by software setting.
Summary of the invention
For solving the data transfer bandwidth broad that existing virtual display technique exists, the sweep speed height, the circuit complexity, showing that digital ratio the unclear phenomenon of writing can occur when drawing literal, can not select real mapping display mode and these defectives of virtual pixel display mode flexibly by software setting, the present invention carries out pre-service by the three primary colours data to the image source pixel, obtain the method for the primary colours video data of corresponding luminotron on the display screen, be implemented on the little display screen of trying one's best and show more information, purpose provides the method that a kind of pixel multiplexing improves display screen image analytic degree.
