TRANSFORMING AUTOMOTIVE DISPLAY BACKLIGHT MODULES: ANALYZING ENERGY EFFICIENCY AND IMPROVING WIDE VIEWING ANGLES

Abstract

This paper revolutionizes the evaluation of in-vehicle display backlight modules through the novel energy ratio of viewing angle concept. A series of experiments validate this innovative approach, showcasing its superiority in assessing energy utilization and reducing errors. The results reveal a 29% improvement in viewing angles (ID) performance and a 12% increase in the energy ratio for Type C lighting patterns compared to Type B. This transformative method offers precision in backlight module design, meeting user expectations for brightness, viewing angles, and energy efficiency. The study emphasizes the role of backlight optical films with wide-angle diffusion functions, aligning with sustainability goals in the transition to electric and hybrid vehicles. This research paves the way for a brighter, energy-efficient future in automotive displays.
