LCD and LED screens, what's the difference in look?

2011-12-01 Thread Dane trethowan

Hi!

I'm just curious.

What's the difference between the look of a LED and a LCD screen, is one 
sharper than the other.


was going through the specs of my HP Entertainment Notebook PC and I 
noted that it had a 15.2 LED display, my Apple Macbook which is 
considerably older has a 13.5 Inch LCD display.

RE: LCD and LED screens, what's the difference in look?

Dane,

As I understand it LED technology is relatively new to what might be
termed small screens and in this regard a comparison between LCD and LED
in terms of length of life can be guessed at, although probably good
guesses.

In some circumstances, the LED screen should offer better contrast
regarding RGB but there are a range of other issues too.

In no way claiming any great knowledge on the subject, I feel sure there
will be more comprehensive replies especially relating to your main
question concerning the look comparing both.

Regards,

Roger.

I'll comment on your post, here, which has some very
good points.

Mrs. Lynnette Annabel Smith writes:
 Hello Martin and all

 As I said, I think, Martin, that you may not be aware of the fact that we 
 have to pay a license fee to watch this sort of stuff. That license is 
 rigorously enforced and breaking the rules leads to a 1 thousand Pound 
 fine, plus a 28 day prison sentence and a conviction as a criminal if 
 caught.
 
 The IF signals of the TV or video equipment are used by detector vans 
 with specialist equipment which go around at all hours of the day and 
 night. They check every street at random times and the vehicles are 
 unmarked; so you can't tell when they are there. That fact, the fact that 
 we have to pay for something which others are trying to get for free, is 
 the only reason why I am in favour of the ban.

Actually what you have there is a forced subscription.
The detector vans and the data base and infrastructure to
support them plus all the staff to occupy them is utter lunacy.
I'd like to laugh and say something like, Oh! those British.
How weird, but that's totally missing the point as to how far
governments and private industry will go sometimes to enforce
behavior that is not voluntary or unpopular or both.

It must cost a fortune to outfit those vehicles, pay the
drivers, technicians, engineers and computer programmers and I
am sure things go wrong from time to time like any good
bureaucracy.

I am surprised that England has not done one of the
following things:

Abolish the license fee and all compliance
infrastructure and collect the taxes some other way that you
can't avoid such as sales taxes or the VAT.

They could encrypt the television signal so that you
must pay for it just like satellite reception. Again, axe the
enforcement infrastructure because it wouldn't matter. Didn't
pay? it doesn't play.

 Some of the other TV 
 channels in the UK have other reasons for banning access to their 
 content. And the primary of those is copyright. They take out viewing 
 rights agreements with the owners of the content, and the production 
 companies who sell it on to the TV stations. Those agreements contain 
 copyright clauses which prohibit the TV channels from making their 
 content freely available. That, and that only, is the reason why they 
 prohibit access to overseas individuals. I've done some checking and 
 actually, the network providers of VPN and other access points are 
 themselves liable for prosecution it seems if their clients use their 
 facilities to access copyright material. I don't know what the situation 
 is regarding the person themselves; but my information is that the 
 provider of the services usually makes it quite clear to people who 
 subscribe that their agreement is that they don't use the service for any 
 illegal activities. Therefore, if the provider is made aware of such 
 abuse by the broadcaster or copyright holder, they apparently take a very 
 dim view of it and take the appropriate measures. This is only what I'm 
 being told; I am no expert.

Here, local television stations broadcast their signal
over the air, through cable systems and, here's the problem, via
satellite for viewers who live either too far away from the city
to receive a proper signal over the air or for people who
subscribe to satellite and need some way to get signals from the
nearest city, also.

I could, in theory, watch the local TV of New York City
even though it is 2000 miles away but one is not really supposed
to do that because local stations sell advertising that I don't
receive. It's a variation on who pays for what, again.

The signals are encrypted and the company sells you a
decoder for your area. 

There is a black market which I truly do not know
anything about in which people sell cracked decoders for
somewhere between what a legal system would cost and free and
federal agents usually find these people and they are in big
trouble when cought.

It is not a huge industry, here, but you hear about it
from time to time when somebody gets cought.

One of the satellite companies did a very clever thing a
few years ago.

There were a bunch of illegal receivers out there and a
large number of folks had bought them because of a premium
sports package that they were stealing. The satellite company
knew what type of cards the pirates had so they sent a short
program, a few bytes at a time, to all these folks while, at the
same time, they sent their paying customers new cards that were
immune from what was about to happen.

Each day, they sent up a few more bytes of the program
which the receivers wrote to the illegal cards. On one of the
biggest Sunday football days of the year, they sent the final
few bytes of the program which caused all the illegal smart
cards to go in to an endless loop of nothing which effectively
killed the decoders.
