By all current, do you mean all current in market minus discontinued, or you mean, ever? Because i recall there are quite a number of direct LED back lighted LCD panels besides edge .

I totally agree with you. But then again, you gotta see the demographics of the buyers. In different coutries, the major purchasing force of LCD tvs differs. While there are some technical, geeky, well versed in the technogical aspects of all LCD related stuffs that buys these tvs, a rising major force is the average housewife, which to them, the first thing they usually want to know, is what size tv fits their decor. Once they got a inch decided, they then proceed to see what design goes well with their home. Nope, PQ is towards the very back of the selection criteria xD. To them, TV is a TV, if can watch show, then its doing its job. Just make sure it looks well in the house.

So yeah, these 'rising force' is gonna sooner or later dilute the PQ of LCD tvs because the manufacturers will then start to put more emphasize on physical form over performance.

Pity huh.
