Senior Hardware Engineer – Display Optics

Responsibilities

• 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.
