The Z series has adopted the Backlight Master Drive technology. The BMD is precision backlight boosting technology, which expands brightness and contrast to tap the full combined potential of 4K HDR. To further enhance contrast, the BMD features a dense LED structure with a super accurate lighting algorithm, discrete lighting control, and a unique optical design with a calibrated beam LED, delivering dynamic range with incredibly deep blacks and dazzling lights. The discrete LED control feature allows the BMD to dim and boost each LED individually. With the local dimming algorithm, the BMD aims to deliver total precision for unparalleled contrast and realism.
