Electronic Device With Low Reflectance and Color Matched Display Border

摘要

A display may have an active area in which pixels display images through a transparent display layer. An opaque masking material may be formed in an inactive border area adjacent to the active area. The opaque masking layer may include particles such as carbon black particles to provide the opaque masking layer with a dark appearance. The color of the opaque masking layer may be adjusted by incorporating additional particles such as titanium oxide particles. Particle size for the carbon black particles and the index of refraction of the opaque masking layer may be adjusted to reduce reflectance in the inactive border area. A transparent conductive layer may be supported by the transparent display layer. Index-of-refraction matching layers may be interposed between the transparent conductive layer and the transparent display layer. The opaque masking layer may be interposed between the matching layers in the inactive border area.

1. A display having an active area and an inactive border area adjacent to the active area, comprising:
pixels that display images in the active area; a transparent display layer through which light from the pixels passes; a layer of opaque masking material on the transparent display layer in the inactive border area; a transparent conductive layer on the transparent display layer; a first index-of-refraction matching layer that is interposed between the transparent conductive layer and the transparent display layer in the active area and that has a portion in the inactive border area; and a second index-of-refraction matching layer that is interposed between the transparent conductive layer and the transparent display layer in the active area and that has a portion in the inactive border area, wherein the layer of opaque masking material is interposed between the portion of the first index-of-refraction matching layer in the inactive border area and the portion of the second index-of-refraction matching layer in the inactive border area.
