Abstract

Methods and apparatus for use in the manufacture of a display element. Some embodiments include a method for selective pick up of a subset of a plurality of electronic devices adhered to a handle layer. The method comprises modifying a level of adhesion between one or more electronic devices of the plurality of electronic devices adhered to the handle layer, such that the subset of the plurality of electronic devices has a level of adhesion to the handle layer that is less than a force applied by a pick up tool, PUT. This enables selective pick up of the subset of the plurality of electronic devices from the handle layer by the PUT.
