摘要: The invention relates to a planar light distribution module for a display, comprising a light guide plate through which light coupled in via at least one side face can propagate by means of total reflection, and at least one out-coupling device (2), which is applied on one or both of the main faces of the light guide plate (1), is in optical contact therewith and has a multiplicity of holographic optical elements (13) formed therein, which are configured in such a way that they can couple light out of the light guide plate (1), the light distribution module being characterized in that the holographic optical elements (13), independently of one another, have an extent of at least 300 μm in at least one spatial axis extending parallel to the surface of the out-coupling device (2). The invention furthermore relates to an optical display, in particular an electronic display.

摘要: The invention relates to an illumination device for illuminating at least one light modulator system of a liquid crystal display, the device comprising at least one waveguide substrate for guiding at least one targeted light beam that can be coupled into the waveguide substrate. The waveguide substrate is at least in optical contact with at least one holographic optical decoupling substrate comprising a plurality of decoupling regions and a decoupling region is at least designed to decouple part of the targeted light beam in the form of a plurality of sub-beams in the direction of the light modulator system. At least one diffuser module is provided, said diffuser module being designed in such a way that at least the outermost sub-beams of two neighbouring decoupling regions are at least adjacent to one another before exiting the diffuser module.
