How to Deal With Color Difference of LED Display

Berichtdoor robin max op di 23 aug 2016 7:59 am

 LED display at the time of sale will inevitably produce poop. Potter Since these are different batches of the product, there are inevitable differences in brightness, display ineffective after assembly, we must use this time point by point correction technique.<br>
 <br>
Resolve differences by-point correction is an electronic screen for lifting the LED brightness uniformity and color fidelity technology through each pixel <a href="http://www.visslighting.com/">LED display</a> on the data acquisition, the correction coefficient matrix is ​​given, then back to the screen control system, the pixel differences drive, brightness and color differences weakened area.<br>
 <br>
By-point correction is an electronic screen for lifting the LED brightness uniformity and color fidelity technology through each pixel <a href="http://www.visslighting.com/en-us/product/23.html">LED dance floor</a> on the data acquisition, the correction coefficient matrix is ​​given, then back to the display control system achieve pixel differences drive, weakening terms of brightness and color difference. This technology can make different batches of files tail spliced ​​together, but also to clean delicate screen display, true color natural.<br>
 <br>
First, depending on the application, point by point correction system is divided into two types:<br>
 <br>
1, a single LED Case-by-point correction, in-line-by-case calibration, to ensure that each box factory achieve a high degree of uniformity;<br>
2, live big-screen-by-point correction, is displayed in full-color LED large screen to select the appropriate scene viewing locations on-site calibration, on-site observations to ensure that the display position to achieve a high degree of uniformity;<br>
 <br>
Second, point by point correction is divided into color correction and brightness correction.<br>
 <br>
1. LED luminous intensity brightness correction is a correction. At the moment, due to some lack of good color correction instrument resolving power, and can not accurately measure the difference in the spectrum, it can only be measured on the luminous intensity and color deviation can not be accurately measured.<br>
2. chromaticity correction means have a strong ability to distinguish color photometric instrument calibration mode, it can get a more accurate measurement of those luminance, chrominance value of the LED.<br>
 <br>
Thus, the use of different batches of the same wavelength but the main tail stall<a href="http://www.visslighting.com/"> LED screen</a>, there is a need for correction of luminance and chrominance. Both to ensure consistent brightness across the LED electronic display screen, and can exhibit a normal color screen display. Last profile products are generally larger than the market price profile products a price advantage, point by point correction technology, these different batches of files tail and can function properly, the LED display to improve product value, but also for customers to save an enormous amount of costs.
