DISPLAY HAVING A BACKPLANE WITH INTERLACED LASER CRYSTALLIZED REGIONS

摘要

Systems including and methods for forming a backplane for an electronic display are presented. The backplane includes interlaced crystallized regions, and the interlaced crystallized regions include at least a left column of crystallized regions and a right column of crystallized regions. The left and right columns include rows of crystallized regions with gaps disposed between each of the rows. Furthermore, each crystallized region in the left column extends into a corresponding gap in the right column, and each crystallized region in the right column extends into a corresponding gap in the left column.

1. A method of forming a backplane for an organic light emitting diode display comprising
depositing a first material on a substrate; crystallizing the first material to form a second material, wherein crystallizing the first material comprises:
forming a left column using a first laser scan, wherein the left column comprises a plurality of left crystallized regions with a plurality of left gaps disposed between crystallized regions of the plurality of left crystallized regions; andforming a right column using a second laser scan, wherein the right column comprises a plurality of right crystallized regions with a plurality of right gaps disposed between crystallized regions of the plurality of right crystallized regions,wherein each crystallized region of the plurality of right crystallized regions is at least partially disposed within a corresponding left gap of the plurality of left gaps and each crystallized region of the plurality of left crystallized regions is at least partially disposed within a corresponding right gap of the plurality of right gaps.
