The OptoAlign® E3-UV-600-A Exposure Equipment, ELS-CDUC-05 and BenchToPTM Exposure Equipment are research and development tools designed to identify the process parameters for the optical alignment of liquid crystal displays (LCDs) and functional optical and electronic polymer films. 

OptoAlign® technology is a non-contact, dust and static-free alignment process that increases yield and enables new LC display modes and LC device applications. OptoAlign® materials, processes and equipment use Elsicon’s proprietary technology to provide a turnkey non-rubbing alignment process for LCD manufacturers. For example, TN, STN, Multi-Domain, VA, IPS and FLC display modes, and LC polymer films for compensation films have been demonstrated with this equipment, OptoAlign® processes, and developmental materials.  

The OptoAlign® E3-UV-600-A Exposure Equipment  is engineered with lamp and optical components that are fully scalable to pilot line and mass production. The UV lamp systems and optical components are highly stable and reliable. Consequently, the process parameters developed using this equipment will be usable for pilot line and mass production.  Full automation of all the process parameters and increased flexibility to test new optical configurations makes this system well suited for the development of pilot and production processes.

The OptoAlign® ELS-CDUC-05 Exposure Equipment  is a less automated alternative to the E3-UV-600-A but still gives the operator the flexibility to test a variety of exposure and process conditions.  The transport system is a conveyor and the system is configured and re-configured manually.  The range over which the process parameters can be varied with this system is significantly narrower than the E3-UV-600-A.  Nitrogen inerting capability is standard with the ELS-CDUC-05.  The process parameters developed using this equipment will be usable for pilot line and mass production.

The OptoAlign® BenchToPTM Exposure Equipment is a compact bench top model for processing smaller film samples, test LCD panels and LC devices.  This lower cost alternative to the OptoAlign® E3-UV-600-A and ELS-CDUC-05 Exposure Equipment  offers researchers the basic flexibility needed to test new concepts and applications of polarized UV processing of materials.   The compact size has some relevance to pilot and production level work but is best suited for R&D. 

Elsicon has expertise in a variety of polarizing technologies such as dielectric, wire grid, Brewster angle and film polarizers and lamp technologies such as microwave, arc and excimer.  The choice of polarizing and lamp technology depends on the needs of the customer and application.  

We also offer systems for providing an inert atmosphere during exposure of samples and radiometric monitoring of the equipment.
