Light guide plate molds
Micro-groove machining technology provides the nano-order machine precision light guide plate molds need
We provide molds for light guide materials used as lighting in flat panels, using a post-machining cleaning process for high quality.
Light guides are a must for backlighting LCD TVs and mobile phones, and ours provide high precision, dimensional accuracy, and pitch accuracy.
Toray Precision's ultra high-precision machining equipment allows us to handle a multitude of customer requests.
Applications
- Molds for light guides (backlights for flat panels)
- Other MEMS / bio-related applications
Features
- Support for large sizes
- Wide variety of groove types, including corner, semicircle, grating, trapezoidal, dimpled, etc.
- Narrow-pitch (several µm) machining performance
- Sharp (1 µm or less) forms on groove and ridge lines
- We can machine 60-inch sizes (1500 mm x 900 mm).
- Pitch accuracy of 1 µm or less possible with a 50 µm pitch.
- Sharp (1 µm or less) forms on groove and ridge lines
- Can also be used as molds for optical parts (nano-imprinted molds, microlens array molds).
