Abstract
The disclosure relates to an optical waveguide for a display device and to a method for controlling such an optical waveguide. The optical waveguide has a switchable input coupling hologram and an electrode for switching the switchable input coupling hologram. The electrode is designed as an electrode array having a pixel matrix. The pixels of the pixel matrix can be switched individually. For this purpose, the pixels can be connected to a voltage source. Controlling the pixels is performed by a control unit.
