About the role
Key responsibilities & impact- Design and optimize the optical film stack architecture for LCD modules used in automotive interior displays
- Select appropriate brightness enhancement and optical compensation films (e.g., DBEF, BEF, diffuser, prism, etc.) based on application and system requirements
- Conduct film stack simulations and ray tracing analysis to evaluate trade-offs in brightness, viewing angle, color shift, and efficiency
- Collaborate with display panel suppliers to define and validate film stack structures under automotive conditions including temperature cycling, humidity, vibration, and sunlight exposure
- Analyze optical measurement data (e.g., luminance, contrast ratio, haze, reflectance, viewing cone, color shift) and correlate with film stack properties
- Investigate and resolve optical issues such as non-uniformity, Mura, and halo artifacts related to film stack interaction
- Interface with materials suppliers to evaluate new film materials and lamination processes for enhanced durability and optical performance
- Provide technical direction on film stack DFM and ensure robust performance across the display supply chain.
Requirements
What you’ll need- Bachelor’s degree in Optical Engineering, Physics, Display Engineering, Materials Science, or related field
- 5+ years of experience in optical film stack design, display optics, or light management systems
- Deep understanding of LCD optical architecture, particularly brightness enhancement and polarization management films
- Familiarity with film performance metrics such as halo, haze, birefringence, angular luminance, and reflectivity
- Proficiency with optical simulation and analysis tools
- Experience with optical characterization equipment (e.g., imaging colorimeters, spectroradiometers)
- Understanding of automotive optical performance requirements.
