Description of the Invention ((Summary of the Invention) The present invention relates to a technology for guiding the color difference and wavelength of a light-emitting diode, in particular, it refers to an application using a specific correction unit to correct the deviation of the three primary colors in advance and promote mixing. The color naturally becomes the standard color. (Technique to be solved) The present invention is based on the light-emitting diode (LED) with three primary colors (red, green, and blue). Theoretically, it should be possible to achieve the combination of the three primary colors. The effect of color, but because of technical and production control problems, the original three primary colors have been deviated. Therefore, the mixed color results naturally deviate more, and the purpose of using the three primary colors is also lost; therefore, if a correction can be applied Units (such as road boards or ICs) make the two primary colors correct before the blending, that is, correct this deviation degree in advance, and then the result of blending the colors can of course form a standard color. (Objective of the invention) The main purpose of the invention is to provide a method that can correct the color difference and make the light-emitting diode emit a standard color, which mainly includes red, green, and blue The crystal or lamp of the primary light emitting diode (L ED) has reached a standard color light after a correction process to compensate for the color mixing deviation caused by the color difference, wavelength, and on-voltage of the original light emitting diode.俾 Improve the yield of the product 'and reduce the cost, and further achieve the goal of generalization.
