Description
Technical field
The present invention relates to display alignment technique field, be specifically related to the bearing calibration of a kind of LED display bright chroma.
Background technology
Due to the reason such as discreteness of the discreteness of LED luminescence, Decay Rate and circuit components, there is brightness and the inconsistent phenomenon of colourity in LED display, seriously affects display quality.In order to overcome LED display brightness, colourity non-uniformity, pointwise correction technology is arisen at the historic moment, and development rapidly, and it can improve the homogeneity of LED display significantly, improves display quality.
According to the difference of application scenario, pointwise correction technology can be divided into two kinds again: a kind of is correcting (also claiming casing to correct) by case on production line, and another kind is that on-the-spot large-size screen monitors correct (also claiming straightened up in place).Straightened up in place technology can select suitable viewing place to correct, and ensures that LED display reaches satisfied display effect in applied environment at the scene, but site environment complicated and changeable and strange land technical support are the difficult problems that restriction straightened up in place faces.
It is produce the one that line corrects that casing corrects, and mainly in order to eliminate brightness between box house and casing and colourity difference, improves the homogeneity of LED display after splicing.In order to ensure the homogeneity of LED screen body of dispatching from the factory, reduce technical support cost, casing alignment technique just embodies oneself peculiar value, and it significantly can improve the display quality of display screen after splicing, and straightened up in place efficiency is higher relatively, be not subject to the restriction in time and place.Along with the development of LED display production firm, casing alignment technique manufactures a part indispensable in link by becoming LED display, has a good application prospect.In addition, casing corrects the correction that can also be used for LED lease screen.Lease screen is generally made up of the batch casing purchased at times, the luminance difference, color gamut space difference etc. of different batches casing result in full screen image quality decrease, casing correcting scheme now can be adopted to carry out correcting by case to each lease casing, finally reach the object that bright chroma is consistent, improve display quality.
Similar with straightened up in place, for each LED box, the process that casing corrects comprises data acquisition, data analysis, desired value setting, correction coefficient calculating etc.; Correction coefficient is uploaded to receiving card by control system after generating by correction coefficient, realizes the object that LED box bright chroma corrects.But, in prior art correction coefficient upload that convenience is poor and efficiency is not good, urgently improve.
Summary of the invention
Therefore, for overcoming the technological deficiency that prior art exists, the present invention proposes the bearing calibration of a kind of LED display bright chroma.
Particularly, a kind of LED display bright chroma bearing calibration that the embodiment of the present invention proposes, comprise step: carry out scene utilizing multiple LED box to be corrected and build splicing LED display after the receiving card of described multiple LED box to be corrected is connected to the control system of described LED display, application software reads the hardware identifier information stored in described multiple LED box to be corrected of described LED display; Described application software utilizes the hardware identifier information of the described multiple LED box to be corrected read to go out the correction coefficient corresponding with the hardware identifier information of described multiple LED box to be corrected from correction coefficient data library lookup, and wherein said correction coefficient data storehouse comprises the correction coefficient of multiple casing and the hardware identifier information of the described multiple LED box corresponding with described correction coefficient; And the correction coefficient of the described multiple LED box to be corrected found out is uploaded to the bright chroma that described multiple LED box to be corrected carries out storing to realize described LED display respectively and corrects by described application software automatically.
In one embodiment of the invention, the hardware identifier information stored in described multiple LED box to be corrected comprises the casing title of described multiple LED box to be corrected.
In one embodiment of the invention, the hardware identifier information stored in described multiple LED box to be corrected comprises the receiving card title in described multiple LED box to be corrected.
In one embodiment of the invention, described correction coefficient data storehouse is casing title and the correction coefficient relational database of LED box.
In one embodiment of the invention, described correction coefficient data storehouse is the casing title of LED box, receiving card title and correction coefficient relational database.
In one embodiment of the invention, the bearing calibration of above-mentioned LED display bright chroma also comprises step: described application software from connect described multiple LED box to be corrected receiving card LED controller read splicing and the arrangement mode of described multiple LED box to be corrected of described LED display, and according to described splicing and arrangement mode the correction coefficient of the described multiple LED box to be corrected found out merged and is converted into full frame correction coefficient for uploading.
As from the foregoing, the correction coefficient in the embodiment of the present invention can realize robotization and upload, and without the need to working, people too much intervenes, simple operation, can improve widely and correct upper transfer efficiency, save time, manpower and financial resources.
