You might often read the buzz term Local Dimming. It becomes one of the major technology most brands are competing in the LED LCD industry.
Edge-lighting is one of the most popular solution as LED LCD industry advanced since fewer LEDs means less cost and better energy efficiency. But on the other side, the edge-lit LED LCDs produce poor uniformity. It’s especially noticable on dark scenes. With local dimming technology, the zones behind the dark area will be dimmed to improve the contrast ratio. While different manufactures implement different solutions on the local dimming, the results on the contrast ratio could vary quite a lot. The number of the LEDs also limits the number of dim zones. That’s why edgelit LEDs could only have 8 dim zones. Sometimes it’s also referred as sudo local dimming.
Another solution for the local dimming is to use full array LEDs instead of only put the LEDs on the edges. With increased number of LEDs, the screen could be split into more granular zones. The following video illustrates the difference of these technologies.
From the above comparison, Vizio M75-C1 only falls short in response time and energy efficiency. Overall, they’re both great TVs for most occasions. If you’re like me, not a picture purist, why bother to spend extra money.
