Abstract
The utility model discloses a kind of LED display Intelligent debug system, be provided with multichannel unit lamp plate and lamp plate for subsequent use, each unit lamp plate and lamp plate for subsequent use are respectively arranged with LED display circuit, driving circuit, Flash chip is respectively arranged with in driving circuit, also include four and select a data selection circuit, four select a data selection circuit by Ethernet access Data buffer, Data buffer is by being connected with external network, and in unit lamp plate and lamp plate for subsequent use, Flash chip selects a data selection circuit FPDP to be connected respectively by spi bus and four.The utility model sets certain storage space to every a slice lamp plate, and is independently stored on lamp plate by the correction data of correspondence, without the need to again correcting after replacing lamp plate, only needs refresh routine again.
Description
Technical field
The utility model relates to field of LED display, specifically a kind of LED display Intelligent debug system.
Background technology
LED display is because there is brightness high, fast response time, be easy to the advantages such as splicing more and more accept by market, and display products is after assembled getting well, because each unit box is because of the problem of machining precision, physical dimension size cannot be avoided having deviation slightly, be directed at piece between casing excessive or too small, whole screen is when showing solid color (as white light), particularly closely spaced LED display, be easy to the gap seen between casing, simultaneously, due to the fabrication error of each lamp pearl when producing, and the error of unit lamp plate when paster is assembled, single-point or partial area brightness not first-class phenomenon is there will be when being directed at normal display, all these problems, at present all can by whole screen point-to-point correction system by regulating separately the height situation of its original brightness to each pixel, and it is completely the same to reach overall picture brightness.After whole screen correction completes, correction data is normally stored in inside casing receiving card in units of casing, each unit lamp plate is sent to, to ensure that the brightness of all pixels of whole screen when normal work reaches consistent standard with colourity after directly reading the data of receiving card when follow-up correction is opened.
Although display screen spot-spot correction system can solve above-mentioned all problems completely, but when unit lamp plate or pixel have damage, normally unit lamp plate is changed, and correction coefficient is for mate with former lamp plate, so need again to correct whole screen, and to correct be gather rear comparing calculation based on high precision camera to shades of colour display frame to go out rational data and be dispensed to each pixel, for guaranteeing the effect after correcting, the a large amount of mathematics of usual needs collection carries out analytical calculation, external environment light also has considerable influence to gathered data simultaneously, so, correcting this step is all carry out in the darkroom of specifying in factory, damage once the follow-up lamp plate of client and change, calibration function can only be closed, lose the effect after original correction.
utility model contentthe purpose of this utility model is to provide a kind of LED display Intelligent debug system, Problems existing during to solve in prior art LED display the debugging of unit lamp plate.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of LED display Intelligent debug system, it is characterized in that: be provided with multichannel unit lamp plate and lamp plate for subsequent use, each unit lamp plate and lamp plate for subsequent use are respectively arranged with LED display circuit, the driving circuit of driving LED display circuit, Flash chip is respectively arranged with in the driving circuit of each unit lamp plate and lamp plate for subsequent use, also include and select a data selection circuit based on four of FPGA structure, four select a data selection circuit input end to be had the Data buffer built based on FPGA by Ethernet access, Data buffer input end is connected with external network by optical fiber, four select in a data selection circuit and are also provided with Flash chip, in unit lamp plate and lamp plate for subsequent use, Flash chip selects a data selection circuit FPDP to be connected respectively by spi bus and four.
The utility model designs a kind of debug system, sets certain storage space, and be independently stored on lamp plate by the correction data of correspondence for every a slice lamp plate, without the need to again correcting after replacing lamp plate, only needs refresh routine again.
Accompanying drawing explanation
Fig. 1 is the utility model system principle diagram.
Embodiment
Shown in Figure 1, a kind of LED display Intelligent debug system, be provided with multichannel unit lamp plate and lamp plate for subsequent use, each unit lamp plate and lamp plate for subsequent use are respectively arranged with LED display circuit, the driving circuit of driving LED display circuit, Flash chip is respectively arranged with in the driving circuit of each unit lamp plate and lamp plate for subsequent use, also include and select a data selection circuit based on four of FPGA structure, four select a data selection circuit input end to be had the Data buffer built based on FPGA by Ethernet access, Data buffer input end is connected with external network by optical fiber, four select in a data selection circuit and are also provided with Flash chip, in unit lamp plate and lamp plate for subsequent use, Flash chip selects a data selection circuit FPDP to be connected respectively by spi bus and four.
The driving circuit of the utility model for each blade unit lamp plate increases Flash system, at whole screen when producing, just produce a certain proportion of spare unit lamp plate simultaneously, after spare unit lamp plate carries out burn-in test by normal production procedure, correct together with whole screen, and corresponding correction data is stored on Flash, this Flash can also store die-away curve, automatically the record lamp plate cumulative operation time of lamp onboard led simultaneously; After having had these data, if when some lamp plates need to change, first read this lamp plate FLASH information in computer, after having changed new lamp plate, again control information being write in new lamp plate, by reading cumulative operation time, being multiplied by corresponding attenuation coefficient, reduce new lamp plate brightness, there is new bright concealed wire, manually can regulate and write in lamp plate. because regular correction can only store one group of data, can correct by multistage now, and be kept in lamp plate, whole screen display is shown evenly.
