Crysoptix TBF™ Coatable Retarders: Biaxial BA-LT-1000

(≈0,5MB)

Description

Crysoptix biaxial retardation Thin Birefringent Film™ (TBF™) BA-LT-1000 provides efficient LCD optical compensation, superior wide viewing angle performance with high contrast. The TBF™ is produced by coating liquid self-assembling rganic materials on glass or plastic substrate via printing process, such as slot die (roll-to-roll or flat-bed) with subsequent drying. TBF™ coating technology does not require pre-formation of alignment layer on the substrate surface.
The TBF™ retarder can be used as an efficient low-cost internal or external patterned retarder for 3D LCD TV. The retarder improves the performance of LCD by increasing the contrast at oblique viewing angles and completely removing color inversion in VA and IPS LCD.
The printable retarder can be laminated with dichroic polarizer.

Viewing Angle Benefits

The application of BA-LT-1000 retarder to IPS and VA LCD devices drastically increases the contrast ratio at oblique viewing angles (CR more than 100 at viewing angle 60 degrees).

How To Do

Roll-to-Roll Slot Die Technology

The biaxial BA-plate TBF™ retarder is formed from a liquid organic coating material onto the substrate with use of roll-to-roll slot die machine.
Finally, the biaxial BA-plate TBF™ retarder can be laminated together with PVA film between plastic substrates resulting in a cost-effective and durable wide viewing angle polarizer.

Optical Properties of Biaxial Coated Retarder

Environmental Stability
The TBF™ BA-LT-1000 retarder has been subjected to the wet environmental test in harsh conditions (temperature 60°C, and relative humidity 90%) for 1000 hours. The retarder demonstrates the high temperature stability, strong adhesion to TAC and glass substrates, and high durability.
