Title:
LIGHT MODULATION DEVICE FOR A DISPLAY FOR REPRESENTING TWO- AND/OR THREE-DIMENSIONAL IMAGE CONTENT, COMPRISING VARIABLE DIFFRACTION ELEMENTS BASED ON LINEAR, PARALLEL ELECTRODES
Document Type and Number:
WIPO Patent Application WO/2010/149587
Kind Code:
A3
Abstract:
The invention relates to a light modulation device (10) for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device (10) comprises a light modulator (12) and a controller (14). The phase and/or the amplitude of a light wave field (16), which is substantially collimated, can be varied by means of the light modulator (12) depending on the location of the light modulator (12). The light modulator (12) can be actuated by means of the control device (14). According to the invention, in the direction of propagation of the light wave field (16), at least one diffracting unit (20, 38) is arranged downstream of the light modulator (12). The diffracting unit (20, 38) has a variable diffracting structure (22). By means of the diffracting structure (22), the light wave field (16) varied by the light modulator (12) can be diffracted in a variable and predeterminable manner. Further, the present invention relates to a display and a method for producing a light modulation device.
