Comprehensive analysis of edge-edge
There is also a name for edge-edge type is its biggest weakness is not local dimming. Since the LED light focused on the edge of the TV, it must be uniformly output to the light guide plate on the TV screen. Therefore, it is difficult to achieve an area of the screen's brightness. The direct type, since it is possible to achieve through the LED driver chip LED switching to a local, so local dimming on the obvious advantages. Therefore, a new combination of direct and side benefits of both technologies can be local dimming backlighting solution matrix emerged and become the focus of research related to the direction of the backlight manufacturers.
About a matrix can be local dimming backlight solution should be said is a side-entry combined with a direct backlighting technology. From 3M's Optical Systems Division Senior Engineer Lv Yi Hang introduced, the technology back in 2009, there were already associated with backlight factory doing some basic research. Now it seems that many regarded as the direct type backlight mode inductive backlight technology, referred to as matrix backlighting. LED Down lights
The advantage of this technique should be said focused straight down and side of the advantages of both technologies:
1 local dimming: LEDTV had just begun in the early, when there are two kinds of technology had direct type and side-in.
