Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Refer to Fig. 1, a kind of bright concealed wire compensation method of splicing being applicable to LED display that the embodiment of the present invention provides comprises step S101, S103, S105, S107 and S109, specific as follows:
Step S101: the positional information and the resolution information that obtain multiple physics concatenation units of target display screen.Particularly, citing using LED box as physics concatenation unit, after target display screen has configured, positional information and the band information carrying breath (comprising the resolution information being carried LED viewing area by band) of all receiving cards of this target display screen can be got, carry because a LED box receives cassette tape by one or more, then the bright concealed wire one of the splicing between LED box fixes on the border that receiving card band carries region.For simplified illustration, the present embodiment receives cassette tape for each LED box by one and carries, by obtaining all receiving card information of target display screen, comprise receiving card number, each receives the band information carrying breaths such as the initial row, column coordinate of LED viewing area and width that cassette tape carries and height (be also namely expert at respectively and LED pixel quantity) on column direction, positional information and the resolution information of each physics concatenation unit of target display screen can be obtained.Moreover aforementioned location signal and resolution information can be obtained by the parameter directly read on the hardware in the display screen control system at target display screen place, also can be obtained by loading configuration file, or obtained by manual input.
Step S103: the distribution plan drawing out multiple imitate patching-up unit according to described positional information and described resolution information, wherein said multiple imitate patching-up unit with described multiple physics concatenation unit one_to_one corresponding and the size of imitate patching-up unit described in each relative to the resolution equal proportion convergent-divergent of corresponding physics concatenation unit.Particularly, after the positional information obtaining each physics concatenation unit and resolution information, preferably equal proportion convergent-divergent draws out the distribution plan of multiple imitate patching-up unit (respectively corresponding multiple physics concatenation unit).Herein, so-called equal proportion convergent-divergent refers to: the resolution supposing certain physics concatenation unit is 400*300, then the corresponding imitate patching-up unit drawn out is such as rectangle and the dimension ratio of its length and Width is 4:3.Refer to Fig. 2, it illustrates four the imitate patching-up unit drawn out with equal proportion scalable manner, and from left to right, from top to bottom carries out serial number (being such as sequentially numbered 1-4) as its position mark to imitate patching-up unit according to the positional information obtained.
Step S105: the borderline region marking imitate patching-up unit described in each in described distribution plan, in the corresponding physics concatenation unit of the wherein described borderline region of imitate patching-up unit described in each, the region area of single pixel is greater than the region area of single pixel in the corresponding physics concatenation unit of the non-borderline region of described imitate patching-up unit.In the present embodiment, mark boundaries region can adopt following rule and methodology:
Owing to regulating the pixel being typically only concerned about border a line or row during the bright concealed wire of splicing, so the pixel of border a line or row usually only need be marked, and choose conveniently in order to user, the borderline region of each imitate patching-up unit is marked in an exaggerated way on distribution plan, as shown in Figure 3, with the region area making the region area of single pixel (physical picture element point) in the corresponding physics concatenation unit of the borderline region of each imitate patching-up unit be greater than single pixel (physical picture element point) in the corresponding physics concatenation unit of the non-borderline region (corresponding zone line) of described imitate patching-up unit, also namely the quantity of the physical picture element point that the borderline region unit area of each imitate patching-up unit is corresponding is less than the quantity of physical picture element point corresponding to non-borderline region (corresponding zone line) unit area.
In addition, if there is the such as orthogonal splicing bright line or splicing concealed wire that intersect, regulated respectively vertical direction and horizontal direction splicing bright line or splicing concealed wire after, the pixel of both infalls (overlapping region of the corresponding borderline region intersected) can be conditioned twice, thus the situation of bright spot or dim spot may be there is, also the brightness regulating separately infall pixel is namely needed, so also want separate marking to go out the overlapping region of crossing borderline region.Such as shown in Fig. 4, be spliced by four physics concatenation units for target display screen, the non-borderline region of each imitate patching-up unit corresponding to physics concatenation unit (the middle empty band also namely in Fig. 4 in each imitate patching-up unit 1-4), drift angle place or claim the Non-overlapping Domain of the overlapping region of the borderline region intersected (the mesh lines fill area also namely in Fig. 4 in each imitate patching-up unit 1-4) and borderline region (the parallax fill area also namely in Fig. 4 in each imitate patching-up unit 1-4) such as to use different colours to go expression so that the follow-up selection operation of user.
Moreover, after the display effect of viewing target display screen, find the borderline region of corresponding imitate patching-up unit to carry out splicing the adjustment of bright concealed wire for the ease of user fast, preferably each imitate patching-up unit is carried out marking (the mark 1-4 in such as Fig. 2 to 4) according to its position number and corresponding physics concatenation unit on control objectives display screen also shows identical position mark under illuminating state; Certainly, be understandable that, position mark is herein not limited to numeral, also can letter or other symbols, as long as imitate patching-up unit is identical with the position mark that physics concatenation unit is endowed.
Hold above-mentioned, in the present embodiment, [control corresponding physics concatenation unit and also show identical position mark under illuminating state] can in the following way: draw and compensate with Showing Picture, compensate with the width Showed Picture and height and the line direction pixel quantity of target display screen and column direction pixel quantity consistent, compensate a physical picture element point with an image pixel correspondence target display screen on Showing Picture; Compensating with Showing Picture can be 24 RGB trichromatic diagrams, also can be the achromatic sheet of 8; Compensate identical with the gray-scale value of each image pixel upper that Shows Picture and receive at each center (center of the viewing area of corresponding physics concatenation unit) that cassette tape carries region and draw 1-4 in position mark such as Fig. 5; Like this then can be clear that on target display screen splicing bright line or splicing concealed wire, if and on aforementioned distribution plan, select corresponding borderline region to be regulated, just can choose the edge pixel point of splicing bright line or splicing concealed wire both sides quickly and easily, and not need accurately to calculate the position of splicing bright concealed wire.
In addition, due to technique and stitching error, for same splicing bright line or splicing concealed wire, the bright dark degree at different pixel place, edge may be different, now may need to carry out sectional-regulated to borderline region, this time can carry out amplification process to specific one borderline region, this borderline region is divided into multiple territory element, 0-24 such as shown in Fig. 6 amounts to 25 territory elements and each territory element such as corresponding physical picture element point, edge pixel point is selected for user's pointwise, like this then the selection of part edge pixel can be carried out to any one borderline region.
Step S107: the selection of response user operates in selected target borderline region in described distribution plan.Particularly, for determining to splice the borderline region corresponding to bright concealed wire, a kind of typical way is: the monochrome that the display control card such as sending card to target display screen sends resolution etc. large is (such as red, green or blue) or pure color (such as white) view data, referred to herein as compensation view data, in compensation view data, the brightness data of all pixels is all equal, also be brightness data indifference, sending card receives compensation view data and carries out sending to the corresponding receiving card of target display screen to carry out picture display after necessary data are changed, the display effect of watching whole target display screen by human eye vision afterwards determines to there is the bright concealed wire of splicing between which physics concatenation unit, and the borderline region choosing corresponding imitate patching-up unit in aforementioned distribution plan is accordingly as object boundary region, usually, be positioned at the borderline region that same splices bright concealed wire both sides all can be selected as object boundary region.In addition, in order to adding users friendly, preferably, after the selection operation of response user, target display screen highlights the position at each edge pixel point place of the physics concatenation unit corresponding to object boundary region (borderline region be selected), such as, makes the modes such as the rectangle frame of the periphery display particular color of the flicker of each edge pixel point or all edge pixel points corresponding to same object boundary region reach the object highlighted.It is worth mentioning that, also can to expose two adjacent physics concatenation units at a reference mark in step s 107 at every turn, choose and compensate the bright concealed wire of splicing with this one by one.
Step S109: regulate the brightness of the edge pixel point of the physics concatenation unit corresponding to described object boundary region to object brightness, to compensate the bright concealed wire of splicing of described target display screen whereby.Particularly, after choosing the object boundary region needing to carry out splicing the adjustment of bright concealed wire, carry out brightness regulation and watch regulating effect by human eye until compensate the bright concealed wire of splicing to target effect, such as, splicing bright concealed wire and eliminate completely or substantially eliminate.For RGB three primary colours full-color LED display screen, white and red, green, blue three look directly can be regulated during brightness regulation to regulate in proportion, also can regulate respectively by red, green, blue three look.In the present embodiment, brightness regulation and regulating effect are checked and can be adopted following following two kinds of modes:
Mode (1): only regulate the brightness data of the edge pixel point in corresponding object boundary region in the compensation view data of aforementioned brightness data indifference (or claiming gray-scale value indifference) and do not regulate the brightness data of the pixel of other positions with adjusted post-compensation view data, the display control card will post-compensation view data being regulated to be sent to target display screen again, picture display is carried out, for the compensation effect observing the bright concealed wire of splicing according to adjustment post-compensation view data by display control card; At this, the number of times of adjustment can be once also can be repeatedly, and concrete quantity then needs depending on whether bright for splicing concealed wire being compensated to target effect.After bright for splicing concealed wire is compensated to target effect, the brightness adjustment of splicing the edge pixel point of bright concealed wire position just can be decided, brightness adjustment sent to the display control card of target display screen to act on described edge pixel point respectively afterwards, the correction coefficient of renewable whereby described edge pixel point, and then reach the object compensating the bright concealed wire of splicing.
Mode (2): the display control card such as sending card to target display screen sends the such as brightness regulation ratio of brightness adjustment each time of the edge pixel point in corresponding object boundary region (also namely splicing bright concealed wire position), by sending card, described brightness adjustment is acted on the correction coefficient of described edge pixel point to upgrade the luminance component in correction coefficient, it is worth mentioning that herein, for the display screen (being also that its hardware does not store correction coefficient) without correction, can give tacit consent to or be directly 1 by the correction coefficient luminance component of each edge pixel point of software set, all the other components are 0, so that described brightness adjustment is acted on correction coefficient, meanwhile, sending card combines the correction coefficient after upgrading according to the compensation view data of aforementioned brightness data indifference and carries out picture display, for observing the compensation effect splicing bright concealed wire, at this, the number of times of brightness regulation can be once also can be repeatedly, and concrete quantity then needs depending on whether bright for splicing concealed wire being compensated to target effect.Usually, except the edge pixel point corresponding to object boundary region (splicing bright concealed wire position), the correction coefficient of the pixel of other position remains unchanged.After bright for splicing concealed wire is compensated to target effect, the correction coefficient of the edge pixel point corresponding to described object boundary region upgrades, thus reaches the object compensating the bright concealed wire of splicing.
Manner of comparison (1) and mode (2) can find, mode (1) can reduce communication time and hardware handles time, thus greatly reduces regulating time, raises the efficiency.In addition, be understandable that, be not limited to brightness adjustment be sent to the display control card of target display screen to act on the edge pixel point corresponding to object boundary region respectively in mode (1) and mode (2), also can be first brightness adjustment and correction coefficient are combined to form new correction coefficient, be sent to the display control card of target display screen afterwards again directly to carry out correction coefficient replacement.
In addition, it should be noted that, the bright concealed wire compensation method of splicing of the above embodiment of the present invention is not limited in the occasion be applied in using LED box as physics concatenation unit, and it also can be applicable to using LED lamp panel or lamp plate modular array as the occasion of physics concatenation unit; In addition, it is also not limited in and is applied in LED display, also can be applied to other similar panel display screens.In addition, it is worth mentioning that, along with the progress of splicing process, a lot of manufacturer can ensure to accomplish when splicing that the width splicing gap is basically identical, now substantially identical to the regulated quantity of all borderline regions of target display screen, if or go item by item to regulate according to the bright concealed wire of splicing, then a kind of to waste of time, one now can be first selected to splice after bright concealed wire regulated, again regulated quantity is applied on the bright concealed wire of all splicings, regulating time can be shortened widely like this, if the follow-up words that also there is indivedual splicing bright line or splicing concealed wire are finely tuned it again.
In sum, the above embodiment of the present invention can solve the problem regulating the splicing bright concealed wire time longer, do not need the correction personnel of specialty, correction personnel are not needed to calculate the position of splicing bright concealed wire yet, do not need to utilize collecting device collection light tone information and positional information to compensate yet, substantially reduce regulating time, and easily realize, with low cost, simple to operate; In addition the problem that the bright concealed wire of on-the-spot positioning splicing is more difficult is also solved, staff only need know the Position Approximate splicing bright concealed wire, just can find the bright concealed wire position of splicing fast, accurately, easily, the length calculating the bright concealed wire of splicing is not needed yet, even can also specific to certain several even pixel.
So far, apply specific case herein and set forth the principle of the bright concealed wire compensation method of splicing of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention; all will change in specific embodiments and applications; in sum, this description should not be construed as limitation of the present invention, and protection scope of the present invention should be as the criterion with appended claim.
