Electric-Field Alignment for Light-Emitting Element Deposition

The patent introduces an electric field as an intermediary force to align light emitting elements during the deposition process. The electric field application module creates an electric field between the substrate and the light emitting elements, causing the elements to align along electric field lines before being deposited onto the substrate, thereby achieving precise alignment without complex mechanical positioning systems

The patent replaces complex mechanical alignment systems with an electric field-based alignment mechanism. Instead of using precision mechanical stages or positioning systems to align light emitting elements, the invention uses electric fields to automatically orient and position the elements during deposition, simplifying the overall apparatus while maintaining high alignment precision

The patent divides the substrate into multiple regions and places electric field application modules at different locations (e.g., opposite sides of the substrate). Each module independently applies electric fields to its respective region, allowing parallel processing of multiple areas simultaneously, which increases overall alignment efficiency while keeping each individual module relatively simple

The patent combines multiple electric field application modules into a coordinated system that works together to align light emitting elements across the entire substrate. By synchronizing the operation of multiple modules and integrating their control, the system achieves high alignment efficiency for large-area substrates without proportionally increasing overall system complexity
