Optical property normalization for a transparent electrical device

摘要

An electrical device (100) includes a plurality of laterally displaced regions (102, 104) that are substantially transparent, each including a normalized surface (112, 114) that has an optical property that has a normalized value that is substantially the same, one to another. One of the regions (102) includes a portion of an electrical component (106). Additionally, at least one of the regions (102) includes beneath the normalized surface (114) an additional surface (110) and a spectral normalization structure (108). The additional surface (110) has a value for the optical property that is not substantially the same as the normalized value. The spectral normalization structure (108) is disposed with the additional surface (110) such that the normalized surface (114) of ht at least one region (102) exhibits the normalized value.
