Touch Sensitive Display With Graded Index Layer |
摘要 |
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. |
