文森特评测75Z9D

100Z9D真的纯黑

不难看出，1500分区的100寸Z9D，效果远远好于700分区的75寸Z9D和85寸Z9G，仅仅是一倍数量差距为什么效果差异如此之大？

有人说是100z9d是真正满血版动态背光大师，每个灯珠都独立点亮

Backlight Master Drive does not use local dimming zones in the traditional sense but can instead control each LED individually. However, the company refuses to reveal how many individually-controlled LEDs the TVs incorporate.

- “Previously, local dimming was controlled in zones consisting of several LEDs. In combination with the latest accurate lighting algorithm, the discrete LED control of Backlight Master Drive is able to dim and boost each LED individually. This innovative algorithm delivers total precision for unparalleled contrast and realism,” says Sony

但索尼从来没说过100z9d有多少led灯，所以27000个灯这个说法是怎么来的
