Abstract: A multifunctional device layer may include a lightguide substrate having an optically patterned surface and an opposing non-patterned surface. The non-patterned surface of the lightguide substrate is coated with a first material having a first refractive index and the patterned surface is coated with a second material having a second refractive index. The first refractive index may be lower than the second refractive index and each may be lower than a refractive index of the lightguide substrate. A touch sensor may be formed on the coated non-patterned surface of the lightguide substrate, the coated patterned surface, or on an interstitial layer deposited on the coated non-patterned surface or the coated patterned surface. An anti-glare/anti-reflective coating potentially having ultraviolet (UV) absorption properties may be applied to the touch sensor.

Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for improving resolution of black and white images displayed by a display of an image display apparatus, for example an EWD. An electrowetting display device comprising a plurality of sub-pixels. Each sub-pixel comprises a substrate, an electrode layer on the substrate, and a hydrophobic layer on the electrode layer. A first fluid is disposed on the hydrophobic layer and a second fluid is disposed on the first fluid. The second fluid is immiscible with the first fluid. The plurality of sub-pixels is arranged in an angled relationship with respect to horizontal and vertical borders of the electrowetting display device.
