Hello there, BettyBoop. Thank you for sharing your experience with us regarding the OLED55B5PUA. We understand your inquiry about the backlight technology. This TV features an OLED (Organic Light Emitting Diode) display, which means it does not utilize a traditional backlight. Instead, it uses self-lit pixels that turn on and off individually to create light and color, resulting in perfect blacks and infinite contrast. https://www.bestbuy.com/product/lg-55-class-b5-series-oled-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZTKH9 If you have any further questions about its features, please contact us on lgdigitalcare@lg.sprinklrsupport.com, and our team will be more than happy to assist you. —Renzo
