A display quality testing expert with a background in physics and mathematics, likely working in the field of display technology research and development, possibly with experience in image quality evaluation and testing methodologies.
The unexpected high-frequency luminance fluctuation observed in sample unit 734B, potentially stemming from an insufficiently dampened resonance within the backlight assembly, necessitates a thorough investigation and might indicate a critical design flaw, thus potentially resulting in accelerated component failure and compromised image quality.
