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.

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.
