I wonder if they still using the cheaper white LED solution or the RGB ones on this new TV?

cheaper yes...

performance, RGB is better..

also white LEDs are not as stable over time.. they age faster and the color changes..

of coz, if got local dimming that might prolong the LEDS since not every white LED is seeing 100% duty factor when TV turned on..

halo.. I sell LEDs la..

the fact you mention in bold means you don't know how they make white LED.. LOL..

well the white LEDs are based on Blue Dice usually made of InGaN with yellow phosphor coating above it.. over time, due to aging/degradation of the phospor, the white light emitted would shift is hue due to this..

what has that got to do with the lens???

well maybe you are more privileged to some manufacturing trade secrets so thanks for the input on these, but that don't change the fact that RGB is still the better way to produce white color albeit at higher costs.. which was what the initial comments was about..
not to mention, blue+yellow = white doesn't fill up the whole Color gamut very well.. RGBs are better.

as for the comment in bold, the initial bin sorting will not be able to solve aging/time dependent factors on yellow phosphor aging characteristic due to usage over time.. the fact that phosphor ages unevenly across the LCD panel at different LED locations due to different operating times, means there is no way of controlling the aging evenly.....

also as for ultra bright LEDs in both these categories, the other half of the equation is the electronic drive circuits.. that's very important in preserving/prolonging the life and performance of the LEds.. so each TV manufacturer probably have their solutions for these..

having technical discusson ma..

me more on the final end product application of LED side, taiko de_lasoul is manufacturing of LEDS side.. just different viewpoints to share..

dun end up touching each other like Milk..

you tell me.. suddenly ot topic to seeing who can pancut further..

am selling several brands depend on customer request for their project, mostly taiwanese/HK/china..
but as you mention, due to patent issues, some of them are using dies from cree/toyoda gosei etc.. internal details are defined by the manufacturer, so we just follow their P/N as per customer's request in the BOM list of the project.

anyway as for as high brightness LEDs are concern, one thing I learn is that the drive circuits with superior voltage regulation are equally as important as the LEDs them self.. due to the fragile state of these InGaN devices it's important to keep the junction temperature down and also avoid over driving them/over current, longevity depends on the drive circuits other than internal LED chip construction..

strange hor... last time (2-3years ago) many people know plasma looks better but the ones in the market has low resolution and those fullHD version costs 30-40% more than LCD equivalent..

now tables are turned, plasma FHD is cheaper than LED backlight LCD TVs (non local dimming ones summore) and some people still want the more expensive model..

so I think just human nature.. we want the more expensive version (which ever that may be) but hope somehow to get it cheaper than the market price..

what's french fusion meaning?

take kawan's things and use first?

(I mean look at the A950 flagship)

why you want to join 3some?

yes, it's still pretty good (have to put agreeing words, cos ronn watching )

what I meant , cos at the moment, it's not flagship anymore mah..

as for your 2nd statement, it's not about just buying high end electronics , it's about optimizing.. things like SVS or submersive, worth to shell out.. they don't go outdated in 1years time.. the specs alone can remain high end for several years (look at elemental designs's sub which is out for 2+ years already still top end)... or even power amps like XPA-5 etc.. some rotel power amps after 5years still good value to be used in current multichannel AV system setups..
so see what kind of electronics lor.. if BDP, I would stick to low-mid end.. why pay 3k or LX what ever pioneer.. (for me la, just my 2sen..)

what model plasma?

wow this the next sonata..

got stop start button also..

I;m getting the white accord soon.. but this is way better.. die..

koreans + design + technology mah.. still on topic..

but you rite la.. this part I dem scared.. want to sell also 1/2 price in 2-3years..

if same price range, I dun mind.. alas it's not..

well elite ronn with 5 figure subwoofer should consider the CC then... more suit your profile!

jpop/kpop/JAV idol maybe?
