Abstract
A display apparatus includes a multiplicity of picture elements for emitting visible light in different colors in an adjustable manner by means of a plurality of semiconductor layer sequences. Each of the picture elements has a plurality of types of pixels and each type of pixels is configured for emitting light of a specific color. The pixels are each subdivided into a plurality of sub-pixel. All the sub-pixels are configured for emitting light of the same color out of the display apparatus without further color change. At least two sub-pixels within each pixel have emission areas of different sizes. An electrical control unit is assigned to each pixel. The control units are each configured to automatically control the sub-pixels of a relevant pixel depending on an energization intensity in such a way that a light-emitting area of the relevant pixel increases in stepped fashion with the energization intensity.
