Advantages of the LED Display Screens cabinet correction technology

The calibration of LED Display Screens box can greatly improve the display quality of the screen after splicing, and the relative field correction is more efficient, and it is not limited by time and site, and the cost is lower. Therefore, the cabinet correction technology will become an indispensable part in the manufacturing of LED display, with good prospects of application. According to the different application situation, the point-by-point correction technology can be divided into two kinds: one is the box - box correction on the production line. The other is the large screen correction on site (field correction). The following is a description of the LED Display Screenspanel

1. Box body calibration

Case correction is a kind of production line correction, which requires LED screen manufacturers to increase the production line. Under normal circumstances, the housing correction is arranged in the factory before the last link, mainly used to eliminate the box of brightness and chromaticity difference between internal and enclosure, LED Display Screens to improve the uniformity of LED Display Screensafter joining together.

There are three kinds of common practice: one is to put all the boxes together and observe the effect, but the work of splicing is greater than the larger one. Secondly, some boxes were randomly selected to make a splice to observe the correction effect. Thirdly, LED Display Screens the calibration effect of all the boxes is simulated by using the measurement data recorded by the calibration system. The LED production line of box school and simulation assessment/sampling is added.

The cabinet calibration needs to be carried out in the darkroom, and it needs to be equipped with the surface array imaging equipment and chromometer each to measure the brightness and chromaticity information of each box body. In order to ensure that all the calibration process of box body is not affected by the outside world under the impact of environmental conditions, LED Display Screens to meet its goal of luminance and chrominance uniformity, dark room completely sealed, and the temperature and humidity as a constant value, in the process of calibration, and calibration of the instrument must be fixed enclosure, must be placed on the base of the box, avoid the influence of the ground reflection.

2. Field correction

In-situ correction technology can choose optimum viewing place for correction, ensure the LED Display Screens field application environment to achieve satisfactory result of display, but the complex scene environment and long-distance technical support is limited field calibration problems. In particular, some foreign order field correction costs and difficulties are relatively large.

Because of the dispersion, attenuation of LED and discrete components of circuit components, the brightness and chromaticity of LED full-color display are not consistent, which seriously affects the quality of the display. In order to overcome the LED Display Screensbright degree, chromaticity heterogeneity problem, point by point correction technology arises at the historic moment, and is developing rapidly, it can significantly improve the uniformity of LED display, to improve the display quality.

In order to ensure the uniformity of the factory LED screen and reduce the cost of technical support, the box body correction technology reflects its own unique value. The box calibration can greatly improve the display quality of the display screen after splicing, and it is relatively efficient in the field, which is not limited by time and site and has low cost. Therefore, LED Display Screens the cabinet correction technology will become an indispensable part in the manufacturing of LED display, with good prospects of application.
