“…Now it meets the requirements (space, weight, design) for display panels of 260 mm x 160 mm size especially for automotive applications. Antireflective filters -Design and Manufacturing: Special antireflective (AR) filters matching to the RGB wavelengths of fiber lasers were developed and coated on glass plates in the precision inline coating machine PreSensLine of FEP [2] (see Figure 3). The deposition process was reactive magnetron sputtering.…”

Advanced high precision AR coating stacks are key enabler for backlight units for slim holographic 3D displays. This is achieved by an optical functionalization of these units to ensure the optimized incoupling of coherent “RGB” light under an extremely shallow angle of 87°. In order to provide for a homogenous illumination, the elaborate coating stacks had to be applied with optical precision over an area of 300x200 mm² for a display size of 260x160 mm². This was achieved by advanced inline magnetron sputtering, which enables this technology for even larger display sizes. Results of the optical performance, the technology and hardware will be presented.
