Abstract:
A method produces a multicolor LED display, the display including an LED luminous unit having a multiplicity of pixels. First subpixels, second subpixel and third subpixels contain an LED chip that emits radiation of a first color, wherein a first conversion layer that converts the radiation into a second color is arranged at least above the second subpixels and a second conversion layer that converts the radiation into a third color is arranged above the third subpixels. At least one process step is carried out in which the first or second conversion layer is applied or removed in at least one defined region above the pixels, wherein a portion of the LED chips is electrically operated, and wherein the region is defined by the radiation generated by the operated LED chips, generated heat or a generated electric field.
