Abstract: An electronic device may have a touch screen display or other input-output device that includes transparent conductive electrodes. The transparent conductive electrodes may be formed from a material that has a relatively high index of refraction such as indium tin oxide. Surrounding layers of the touch screen display such as a touch sensor substrate and an underlying display layer may have lower index of refraction values. To prevent abrupt index-of-refraction discontinuities that lead to unwanted reflections and visible artifacts on the display, the transparent conductive electrodes may be embedded within a dielectric layer. The dielectric layer may have a graded index of refraction. The graded index of refraction may be varied continuously or in a stepwise fashion by adjusting the composition of materials that are incorporated into the dielectric layer as a function of position within the layer.

Abstract: An apparatus is disclosed. In some examples, the apparatus comprises a cover substrate having a front surface, a first edge and a first cavity adjacent to the first edge. In some examples, the apparatus comprises a plurality of touch sensor electrodes disposed opposite the front surface of the cover substrate. In some examples, the apparatus comprises at least one touch sensor edge electrode disposed within the first cavity on a surface that is angled relative to the front surface of the cover substrate. In some examples, at least one touch sensor edge electrode is disposed on an outward facing curved surface of the first cavity. In some examples, the plurality of touch sensor electrodes are formed from a first conductive material and the at least one touch sensor edge electrode is formed from a second conductive material. In some examples, the first conductive material is transparent, and the second conductive material is non-transparent. In some examples, the second conductive material is formed on a black mask layer disposed around a perimeter of a bottom surface of the cover substrate.
