Printer Monitor Light Guides
The light guide is the part built into the backlight unit (lighting equipment) to guide light to the liquid crystal element (LCD) and now used in a wide range of products. Different sizes of light guides are available, from small models (1 to 8 inches) for mobile phones, vehicle navigation systems, etc. to large models (9 to 15 inches) for notebook computers, etc. As the products' applications range expands, future customer demands will include special surface treatment (gradation, etc.), weight reduction (thinner plate thickness), and accuracy and quality improvements. |
