Embodiment Construction
[0046] The microdisplay with organic light emitting diodes 5 is preferably designed such that it comprises an organic layer (OLED) that emits light according to the current flow on the top metal plane on the CMOS substrate. They can be activated locally, ie as so-called pixels, in which a current flows locally through the organic light-emitting diode 5 via the electrodes of the organic light-emitting diode 5 . The active and passive components responsible for controlling each organic light emitting diode 5 (as regular transistors and capacitors) can be located below the electrodes in a matrix-like arrangement of pixel cells. figure 1 A schematic cross-sectional view of an OLED microdisplay is shown.
[0047] Such as figure 2 As shown, the individual accumulators for the organic light-emitting diodes 5 arranged in rows and columns are written to by corresponding circuits. In this regard, the image input data is received by the electronic control mechanism. The electronic co...
