Cheaper LCD Panels On the Way; Wallets Rejoice

[kato128]

[citation][nom]nukemaster[/nom]LOL. New screen every few months or less[/citation]

But if they cost the same as light bulbs do you really care?

[citation][nom]jacobdrj[/nom]I have never repaired a CRT. Isn't that dangerous?[/citation]

It's as dangerous as walking on a sidewalk. It can kill, you know?

On a 32-inch display, a HCFL panel will require anywhere from four to six lamps, while an older CCFL display can take up to 14 lamps.

Hmm... There is another reason in using such a high number of lamps, besides brightness, which is color and brightness uniformity. All current LCDs more or less suffer from lack of uniformity. Now, I bet it would take quite a bit more engineering behind a HCFL panel, to avoid having it display bands of light... Wonder how thick the diffusing filters would make the panel.

And besides, I had enough with LCD tech already, no matter what method chosen for back lighting them - be it CCFL, HCFL or LED light bulbs or campfires... Shouldn't we be heading towards real OLED displays anyway? 🙁

CRTs are dying. All Electronics die, sooner or later. TV repair shops have almost NO CRTs or Rear-projections TV on the bench nowadays. Because people aren't willing to spend the $$$ to repair them. A typical out-of-warrnaty projection TV repair is about $600. Parts are becoming a problem... again, why make parts for people who'd rather spend $800 on a 48" (720) TV or $1200+ on a 50+" 1080p TV... then spend $600 to repair a 4+ year old SD TV?

When my bedroom 13" SONY died last year, I did spend $70 on a used 27" SONY CRT (it needed a part) that would work with my other Sony A/V remotes... also, the TV has an excellent picture and huge add-on stereo speakers and 4 inputs. It retailed about $800 new. Funny thing, the style looks exactly like the 13" TV... but bigger.

I am looking forward to buying an HD-TV LCD/whatever someday, maybe 2010.

you sir are being a smart ass and an ill informed one at that, catho-ray tubes are infact very dangerous to repair on the back side of the CRT tube is electrically charged coil , the entire back of the tube is also charged by this coil , the charge is powerful enough to kill 20 people if they lined up and touched the back of the crt. Yes i know many people work on these often (my grandfather was always fixing this old black and white set he had). the tube usually disipates this charge after about 3 days of being turned off, making the tube safe to touch, however, in rare cases this electric charge has been know to last for 2-3 weeks. generally it is a very good idea to be really careful when working on old crt tv's. next time you should get better informed before mocking, and making sarcasm at some one else's question, especially when it is a very good question.[/citation]
Offended easily? I do believe the mocking statement could be taken both ways. Yes it can be dangerous; If you think about it, just about anything can be dangerous. However, if you do a little research/are trained in CRT repair in some way, then the risk is not so great.

Anyways, this will be an interestin development. If this can replace the CCRTs with equal/better quality then perhaps I can finally get some more viewsonic professional series monitors for on the cheap.. $600 a piece is a hard bullet to swallow now. Great piece of hardware though.

Its about time...

And I do avoid it when possible. Were it my choice, I wouldn't drive. I have to drive, I don't have to repair a CRT, especially when the repair costs far exceed replacement, not to mention doing it yourself, without training, is probably putting yourself up to unnecessary risk.

Wow, why are people so down about the fact that the power grid of the future is going to be DC?

I have never heard this befor. Can you cite some evidence to show that we are switching to DC? Forgive me for being skeptical, but there was a good reason we use AC today and switching the entire power grid to DC would be a monumental task. If we can't even switch to the metric system, I don't see how the hell we are going to switch our power system.

[citation][nom]jacobdrj[/nom]Very true. Much like we are now trying to reinvent our electric grid to DC. It is possible to do now, where in the 1800's it was impractical. Think of how much more efficient our grid will be when we don't have to use power supplies (AC adapters) on all our fans and electronics.[/citation]



The only parts of our distribution grid that is DC (or ever will be DC) are long underwater interconnects and bulk transfer lines. Shielded underwater interconnects would create too much reactive power losses due to the capacitance between the conductor and the shielding using AC to make them practical for long links, and synchronizing AC grids isn't always feasable when connecting several grids that are on different generation networks, so they connect them with DC lines and use static AC inverters (which can be easily phase sync'ed) on the receiving end to convert back to AC that can be easily synchronized with the receiving network.

LP's still reproduce music better than anything that's been made since. SACD and DVD-A are close, but no cigar.

[citation][nom]kato128[/nom]Last I checked the high voltage line in the CRTs would light you up enough to kill you. But that is easily mitigated by grounding your screw driver as you pop the plug out of the tube (not something to try unless you've been shown how to do it properly though). Also I've found hitting CRTs with hammers isn't that dangerous given that the tubes implode.[/citation]

It takes around 20 mA through the heart to cause something really bad. Maybe even less. This so small but given the body's resistance, this is hard to achieve and even harder to direct to the heart. Hell, there are people who survive to a lightning strike.

I really like the sideways analogy There's also: If you took a bath, and slip on the soap bar.. OMG YOU COULD DIE!

And someone else brang a VERY GOOD point: repair cost often goes beyond replacement cost. And that's a shame IMHO, although it's good for progress. That's what is killing today's electronics techs.

As for hitting with a hammer, year the screen implodes, but glass chunks get thrown and rebounds from the inside and you could end up with some IN YOUR EYE AND DIE!!!

Haha, come on, it's nowhear near an A-Bomb 😛 in fact I'm more frighten to play with a microwave oven than a 36" CRT TV. WAYYYY more frighten.

You MUST be stupid. I've had enough of yourincompetence, and I'm sick and tired of YESTERDAY news.

Sony already uses HDFL backlights in their Bravia TV sets, I'm talking avout products that are already on the market for some time. THIS IS NO NEWS, get over it!
