In recent years, colorful indoor LED display screen in sports venues, road traffic, advertising, leasing and other aspects of the use of rapid growth trend. From the analysis of market demand now, the need for on-site calibration is becoming more and more prominent.

Uniformity calibration can be summarized as: factory calibration, repair calibration, service area calibration and on-site calibration.

Generally speaking, when the LED display runs to a certain moment, all the LED light-emitting tubes will appear brightness attenuation, and the attenuation curve of the three-color tube is not common. Therefore, its brightness will also be reduced compared to the factory brightness. However, the difference in the photoelectric characteristics of each LED light-emitting tube, so that the degree of decline in its brightness error. Therefore, when the display is used for a period of time, the light-emitting tube will appear different degrees of brightness attenuation, so that the display between the pixels is not uniform, and then compared with the beginning of the factory screen, the whole picture will appear a granular display state, or the whole brightness decline. Three-color tube attenuation curve is not common to make the white balance, color temperature and other changes.

In practice, because of the attenuation of the LED tube and other factors such as ambient temperature change, the factory is very excellent display function deterioration of the phenomenon is almost inevitable. The LED display has been installed and then disassembled and transported back to the factory for proofreading, in the project is not completed. In view of these characteristics, the display manufacturer is necessary to carry out after the site of proofreading, to ensure that throughout the life cycle of the display, always maintain the factory display role. Several on-site calibration met
