Based solely from single or anecdotal experiences of myself and friends the Lg reputation is poor as a brand. Our Lg fridge literally caught fire (thankfully we were home). They had no service...

It is complex but fascinating.

PDP cells have a combination of electrodes and dielectric material that enable control of on/off state by controlling wall charge above and below the discharge...

Not trying to confuse the issue here but OLED and LCD are similar in that they both use a TFT to control light output. PDP does not have any TFTs and relies on wall charge to control the on/off...

Changing the shape of the strobe intensity isn't going to accomplish much. The benefit is coming from increasing the effective duty cycle. Anyways, this gradual strobe shape is inherent to PDP and...

DFC is only present when your eyes track motion on a PDP. If you see this artifact on still or paused images then it is not DFC and probably just banding/posterization.

Posterization can be...

I would think that lifetime numbers read in OLED papers are quite specific to the material in a ITO glass slide configuration.

Note that the quoted lifetime numbers of a full production flat panel...

IIRC (a big if since it has been years) the blue PDP phosphors were 1000 times faster than the red/green. So a 0.3ms phosphor would still be 100 times slower than blue?

DFC on plasmas is a motion artifact. Nothing to do with too few subfields. Pioneer uses contiguous subfields in its CLEAR driving method and this method is free of DFC.

The subfield frequency will not change the perception of either flicker or trails. Flicker can only be reduced by reordering the sufields. Improving trails requires either faster phosphors or...

DFC is a result of non-contiguous sub field driving. AFAIK pioneer has always used contiguous regardless of power mode.
