Abstract
Embodiments disclose methods of transferring selected microdevices on a receiver substrate. In one embodiment, a high resolution display comprising a light emitting device (LED) array may be provided to assist in transferring the microdevices. The LED array can selectively either release a layer by using light or cure a bonding layer. The pixels in the display can be turned on corresponding to a set of selected microdevices with predefined intensities to release the set of selected microdevices from the donor substrate.
