Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of preferred embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Additionally, the most only to relating to structure that technical problem solves, composition proposal is when being described, for structure, part and the annexation of known necessity, although below not do not describe, but it is not equal in technical scheme not exist, less should become insufficient disclosure reason.
With reference to Fig. 1, the basic hardware framework of present system, it includes receiving card, keyset and some LED modules.Keyset is provided with hot-swappable testing circuit, and hot-swappable signal for when LED module carries out hot-swappable, is fed back to receiving card by hot-swappable testing circuit, so make receiving card identification be which module there occurs hot-swappable/whether changed new module.
Specifically, receiving card 1 storage inside institute band carries the module ID of module 5 and the chromaticity correction data of module 5 correspondence, major function is the vision signal receiving specially treated, to vision signal decoding and calculate with chromaticity correction data, generate the appointment signal that module 5 can receive and normally show.This signal is transferred to keyset 3 by transmission line 2, and keyset 3 is integrated with display signal amplification circuit and is amplified for the signal that receiving card 1 is transferred to module 5, strengthens and drives.Keyset 3 is integrated with the hot-swappable testing circuit of module, during for module 5 is carried out hot-swappable, hot-swappable signal is fed back to receiving card 1 by transmission line 2, and by the hot-swappable testing circuit identification on keyset 3, receiving card 1 can be which module 5 there occurs hot-swappable.Transmission line 4 is for the signal transmission between keyset 3 and module 5, module 5 internal No. ID and chromaticity correction data having colourity correction data storage chip to store this module, can be read out No. ID on module 5 and chromaticity correction data by transmission line 2 keyset 3 transmission line 4 at receiving card 1 whenever necessary.Module 5 has LED drive chip and LED for showing the vision signal from receiving card 1 decoding process.When being embodied as, hot-swappable testing circuit can according to actual needs and prior art determines concrete circuit structure, one of them scheme is, realized by two IC and supporting auxiliary circuit, wherein when module inserts, one IC is responsible for input and triggers signal, and the control signal that transmission is correlated with is to receiving card 1, another IC is responsible for digital independent etc..
With reference to Fig. 2, in system Booting sequence, after receiving card 1 powers on, first receiving card running environment is initialized, then by transmission line 2, keyset 3, transmission line 4, the memory of all modules 5 is carried out ID reading, read back No. ID of the module ID of receiving card 1 storage inside and module 5 contrasts, if contrast No. ID consistent time, load receiving card internal calibrations data, startup completes；Read back No. ID of the module ID of receiving card 1 storage inside and module 5 contrasts, if ID comparison is inconsistent, receiving card 1 reads this No. ID inconsistent module chromaticity correction data, these data are verified after completing by chromaticity correction digital independent, if verification is passed through, chromaticity correction data are directly stored in receiving card.If verification is not passed through, being repeated once reading, if do not passed through, giving up data, receiving card 1 does not preserve the chromaticity correction data that verification is not passed through.Receiving card 1 loads other and verifies the chromaticity correction data that the module passed through is corresponding.Module vicious for chromaticity correction data, receiving card 1 generates the luminance compensation data corresponding with this module and loads.In preferred version, the correct chrominance/luminance correction data of one or more modules adjacent with this module according to luminance compensation data calculates overall attenuation ratio, and according to this overall attenuation ratio-dependent brightness offset value to this module.Or, luminance compensation data are that receiving card calculates overall attenuation ratio according to the chrominance/luminance correction data of the old module of this position, and according to this overall attenuation ratio-dependent brightness offset value to the new module of this position.
With reference to Fig. 4,5,6, assume that Fig. 4 is the correction data of one of them old module, Fig. 5 is the correction data of a new module, if new module is replaced old module and is directly installed on LED display, due to the correction data of new module and the correction data of old module and differ or mate, will result in the error superposition shown in Fig. 6, poorer than the effect not doing any correction, have a strong impact on display effect.So, in the inventive method, use transition stage temporarily, newly installed new module colourity is not corrected, but calculate overall attenuation ratio according to the correct chrominance/luminance correction data of adjacent one or more modules of the old module of this position or this old module, and after calculating replacing module according to this overall attenuation ratio, need the ratio (i.e. brightness offset value) of whole module brightness regulation, by to this module brightness regulation to reduce the most calibrated harmful effect caused of colourity, improve the display consistency of whole display screen.Brightness offset value calculates can multiple method according to actual needs, as with reference to Fig. 4, calculates the mean value of the chromaticity correction data of pixel on module, and using this mean value as brightness offset value etc..Or module is divided into some regions, calculate the mean value of the chromaticity correction data in each region, and using this mean value as the brightness offset value etc. of pixel in region.
