OPTICAL MEMBER AND DISPLAY APPARATUS COMPRISING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210604 titled 'OPTICAL MEMBER AND DISPLAY APPARATUS COMPRISING THE SAME
The patent application discusses an optical member designed to enhance the vision recognition rate of a mark used for alignment purposes, such as bonding alignment. The optical member consists of a first layer with a pattern portion and a second layer that covers the pattern portion. The refractive index of at least one of the layers varies depending on different wavelength areas, including a visible ray area and an infrared area with longer wavelengths. The difference in refractive index between the two layers is greater in the visible ray area than in the infrared area.
- First layer with a pattern portion
- Second layer covering the pattern portion
- Varying refractive index in different wavelength areas
- Greater difference in refractive index in the visible ray area
- Designed to improve vision recognition rate for alignment marks
- Potential Applications:**
- Manufacturing processes requiring precise alignment - Display apparatus for enhanced visual recognition - Optical systems for alignment in various industries
