A:Answer Hello there, Jeff. Thank you for reaching out to us with your question. We understand your inquiry regarding the dimming technology used in the OLED48B5PUA and how it manages light levels across the screen.
The OLED48B5PUA features our advanced Pixel Dimming technology rather than the traditional local dimming found in standard LED-backlit televisions. Because this is an OLED (Organic Light Emitting Diode) display, each of the over 8 million pixels is self-lit and can brighten, dim, or turn off completely and independently. This allows the unit to achieve "Perfect Black" and infinite contrast, as there is no light bleed from bright areas into dark areas of the image. Our α8 AI Processor 4K Gen2 works to manage these individual pixels with incredible precision, ensuring that you receive a stunning and accurate picture for all your favorite content.
