    Abstract: In at least one embodiment, the semiconductor layering sequence (1) is designed for generating light and comprises semiconductor columns (2). The semiconductor columns (2) have a respective core (21) made of a semiconductor material of a first conductivity type, and a core shell (23) surrounding the core (21) made of a semiconductor material of a second conductivity type. There is an active zone (22) between the core (21) and the core shell (23) for generating a primary radiation by means of electroluminescence. A respective conversion shell (4) is placed onto the semiconductor columns (2), which conversion shell at least partially interlockingly surrounds the corresponding core shell (23), and which at least partially absorbs the primary radiation and converts same into a secondary radiation of a longer wavelength by means of photoluminescence. The conversion shells (4) which are applied to adjacent semiconductor columns (2), only incompletely fill an intermediate space between the semiconductor columns (2).

    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.
