Addressing of a three-dimensional, curved sensor or display back plane

Abstract

A method of forming a three-dimensional electronic device includes forming an array of pixels on a flexible two-dimensional surface, the array being formed according to a three-dimensional structure, the pixels having addressing lines accessible from at least one edge of the array, cutting the two-dimensional surface, the cuts being located to allow the two-dimensional surface to be shaped, and shaping the two-dimensional surface to form the three-dimensional surface, the array of pixels forming the three-dimensional electronic device. A three-dimensional electronic device has a flexible substrate containing an array of pixels, the substrate fabricated as a flat surface, then cut and shaped to form a three-dimensional surface, the array of pixels covering the three-dimensional surface in subarrays corresponding to segments of the three-dimensional surface, and addressing lines for each subarray being accessible along an edge of the three-dimensional surface. A method of forming a three-dimensional electronic device includes providing a flexible substrate, forming address lines on the substrate such that the address lines are accessible at an edge of the substrate, forming pixels on the address lines, the pixels being laid out in subarrays, the subarrays being determined by segments of a three-dimensional surface, and accommodating any cuts that will allow the flexible substrate to form the three-dimensional electronic device in the forming of addressing lines and pixels.
