Structure of the 3D Filter
Q
What layers make up the 3D Filter?
A
The 3D Filter is the complete optical-layer stack applied on top of the display.
It is typically composed of the layers below, and each layer is bonded using OCA (Optically Clear Adhesive).
| Layer | Type | Description |
|---|---|---|
| AR Film | Optional | A layer that reduces surface reflection. Generally has no direct effect on 3D performance itself. |
| OCA | ||
| Cover Glass | Optional | A layer that protects the 3D Lens Sheet. Generally has no direct effect on 3D performance itself. |
| OCA | ||
| 3D Lens Sheet └ Base Film (PET) └ 3D Lens Pattern (UV Resin) | Essential | The core optical layer for glasses-free 3D └ Base Film that forms the lens structure └ Lens pattern that controls the direction of light |
| OCA | ||
| Gap Glass | Conditional | Whether it is used depends on the optical design (e.g., the difference between the target Gap and CL). |
| OCA |
Note
Proper 3D quality requires that each layer be precisely aligned to the optical-design specifications. In particular, the more the lens position or Gap thickness deviates from the optical-design optimum, the more likely crosstalk (X-talk), a reduced viewing zone, and degraded depth become.
