Background technology
The elementary cell of digital picture is single pixel, and the quality of digital picture quality mainly is subjected to the restriction of two factors.Be the resolution (picture element density) and the gray level (color levels that single pixel can show) of digital picture.Same width of cloth image is that the display media of 24 true color is represented certainly than being many that effect that the display media of 16 enhancing looks is represented will be good with resolution for the 640*480 color levels with resolution for the 1024*768 color levels.And LED display is typical digital picture display media, therefore wants to improve the display effect of LED display, should set about from two aspects.The first, improve the density of LED lamp, the second, increase the gray shade scale of this LED display.Aspect the gray shade scale that increases LED display, develop into 256 grades of gray scales from 16 grades of original gray scales, also reserved 1024 grades of gray scale interfaces, on gray shade scale, LED display can satisfy the requirement as digital display terminal.And improving ten thousand of LED lamp density, the display effect that improves LED display by pixel (LED lamp) density on the method increase unit area of physics is infeasible.Mainly contain the reason of following two aspects, (1) is subjected to the restriction of LED lamp and electronic component physical size.LED lamp and its control corresponding electronic component all have the certain physical size, when density acquires a certain degree, reduce unlikely again.(2) be subjected to the restriction of LED dot matrix display module cost.The cost of LED display depends primarily on the quantity of LED lamp.When the area one of display screen regularly, if guarantee the quality of video image the cost of display screen is multiplied by the quantity of increase LED lamp, user and manufacturer all are difficult to bear.
And No. 02224829 utility model patent that Patent Office of China national Department of Intellectual Property disclosed on March 19th, 2003, its name is called " four-picture-element type dynamic pixel control table roof type list core LED display screen ".It adopts the form of sharing pixel to come display video image.By this method, can be under the constant situation of display screen LED lamp quantity, the vision dot density increases by 4 times, and video image quality obviously improves.But, when coming display text information in this way (in the display technique of LED display, the single red LED lamp of general employing is come display text information), then each red LED lamp is as a pixel, point between the then adjacent red LED lamp is apart from obviously increasing (2 times of some distances between the pixel of image of √, as shown in Figure 1, because the pixel of image has adopted technology of sharing, the some distance between the pixel of its image is R '
11To B
21Distance, and the point between the pixel that letter signal shows is apart from being R '
11To R
22Distance), reduced its resolution, so its display effect obviously can reduce.Be to improve in the image display effect in above-mentioned technology, sacrificed the display effect of Word message.
The utility model content
For in the technology that overcomes above-mentioned existing shared pixel in the display effect of improving image simultaneously, but reduced the deficiency of the display effect of literal, and a kind of LED screen of shared with pixel of the display effect that can improve image and Word message simultaneously be provided.
The technical scheme that the utility model adopted is: a kind of LED dot matrix display module of sharing pixel, it includes the dot matrix light emitting source, every four adjacent light emitting sources are formed the 2*2 latticed form and are constituted a pixel, at least include a LED in each light emitting source, the LED that includes three kinds of colors in this pixel, wherein each LED is by different signal controlling, in described each pixel any light emitting source be with this pixel adjacent pixels in a light emitting source.
Described LED dot matrix display module inside is provided with a pcb board near light emitting source, and LED all is welded on this pcb board, and draws the contact pin of respective numbers at this led module back side, and this contact pin is connected with the driving circuit that drives this led module.
Be equipped with a red light emitting diodes in described arbitrary light emitting source.
In each pixel, wherein remove red light emitting diodes in first light emitting source and also be provided with a blue LED, remove red light emitting diodes in clinodiagonal the 4th light emitting source and also be provided with a green LED and be with this first light emitting source.
Red light emitting diodes all can become a discrete pixels separately and shows in the described light emitting source.
The quantity of described contact pin is 12 *, 2 rows, and the quantity of light emitting source is 8*8.
Described light emitting source is for equidistantly arranging.
The beneficial effects of the utility model are: by adopting the method for sharing pixel, each light emitting source all can participate in the demonstration work of 4 pixels, can be in display screen under the constant situation of light emitting source quantity, visual density increases by 4 times, video image quality obviously improves, and the display effect of LED screen also obviously promotes.And when display text information, then each light emitting source then makes the some distance between the pixel still remain on minimum state as a pixel, thus can be when improving the image demonstration, the stablizing effect that the protection literal shows.
