first you said that ea9800 black levels are 0.005 cd/m2 < less than zt60 by one thousands candela , now you say that it`s black levels are 0.001 and superior than zt60 , how much did lg pay to you ?




  • lee neikirk full hd2 years agohi full hd,
    lg didn't pay me anything. My first measurements were compromised by light in the room because it was an on-site test. Getting 0.005 cd/m2 out of an imperfect environment should already say a lot about the integrity of oled mlls.
    In our lab—which is totally dark—i discovered that any light i was measuring between 0.001–0.005 (and occasional marginal 0.000, which is considered an error) was strictly ambient. Even little orange-glowing buttons off of power strips and red led power indicators from disc players can affect light readings when you're dealing with such a tiny amount of luminance.
    The lg's black levels aren't 0.001. That's an approximation i used for both oleds to calculate a theoretical contrast ratio. Their actual black levels are non-light.
    The zt60 is great, but plasmas still use just a tiny bit of electricity to power cells that are black—that's why you get dithering. It's quite ugly up close, but i'm not knocking plasma. I'm just saying i've reviewed two of these now and i've seen no dithering or luminance of any kind from either oled tv while it displayed black. It looks the same as a tv that's off.





    • turrican4d lee neikirka year agoyour measrurements are still compromised. Oled have a blacklevel of zero. 0.001 cd/m2 would be worse than a tuned krp 500m!
      P.s.: It's even worse! You made these 0.001 cd/m2 measurements for the ec9300 and ea9800 up, to, to quote you "that's an approximation i used for both oleds to calculate theoretical contrast ratio. Their actual black levels are non light."
      oh boy! Contrat ratio is infinite, simply as that. And why do you make the ea8800 look even worse than the others with your 0.002 cd/m2? This is ridicolous.




      • lee neikirk turrican4da year agothe limit of human photopic (color-based) vision is 0.003 cd/m2, so unless you're watching a completely black screen, the difference between absolute 0, 0.001, and 0.002 is negligible in most practical viewing conditions and for most content due to changing apls and the luminosity of oled colors affecting the eye's transition rate between vision functions.
        The human eye has limits to the amount of contrast it can resolve, too, so purporting infinite contrast is only theoretically exciting.
        For the purpose of comparison as well as relative scoring, it made much more sense to approximate mll.
