Talk:LCD television

Marketing based article

This article seems to be mainly based on dubious marketing information supposed to stimulate the sales of LCD-TV sets. It should be revised and aligned with other articles on LCDs to remove obvious contradictions and assumptions.

Removed unsourced section "Dead and Stuck Pixels"

I've removed this section from the article because it is unsourced, and I couldn't find anything on Google to support it, either. The Defective pixel article doesn't mention anything about dead pixels being harmful to the whole screen, either, so this section seems to be misinformation.

Stuck pixels are spots on the screen that appear blue, red, white or green on a black background. Dead pixels are spots that appear black on a white background. Dead or stuck pixels are caused from faulty transistors and can create major problems. Stuck or dead pixels affect the integrity of the screen. They will spread over a matter of weeks and can cause the screen to stop working. If the dead or stuck pixels are left for a long period of time (a month or so) the screen will eventually break down and possibly cause a fire due to electrical problems. If one of these dead or stuck pixels are spotted, immediately return the TV to the store from which it was bought. The sooner it is returned the easier it will be to get a replacement TV.

Fixed refresh rate an different 50/60Hz TV standards

Most CRT displays can show both 50Hz PAL/SECAM and 60Hz NTSC. However, most LCDs have a fixed refresh rate (typically 60Hz for computer monitors) so how do they cope with these different inputs? Dropped/doubled frames? I suppose it depends on manufacturer. For games consoles it could be a major problem. I have been unable to locate much information about it though, except a few forum posts complaining about how poor 60Hz looks on 50Hz LCD TVs etc. —Preceding unsigned comment added by Mojo-chan (talk • contribs) 16:26, 19 October 2007 (UTC)

Power consumption ?

Does anybody knows exact power consumption for these types of tv sets ? thank you. —Preceding unsigned comment added by 77.105.61.22 (talk) 19:05, 15 January 2009 (UTC)

Basic information has been added. In general terms an LCD's power usage scales linearly with the screen area, as a side effect of the backlit area growing. PDP's, in contrast, have widely varying power use figures from about even with LCD's to double or even triple the same sized LCD. Maury Markowitz (talk) 16:33, 1 June 2009 (UTC)

Needs more basic background

If an LCD TV is 22", what dimension is that being measured? And is it the visible picture unlike a CRT where it's the tube's diagonal yet some of the tube is hidden behind the casing. What differences account for some being LCD TVs that you can connect a computer to and others being a computer monitor with a TV tuner? -- Ralph Corderoy (talk) 19:55, 4 February 2009 (UTC)

In theory at least, all televisions are measured diagonally and measure only the viewable area. It was common in the past to have two different numbers, but this is less common now because the screen is not "as much larger" as its viewable area due to construction - there's no rounded corners where the glass has to bend towards the back of the screen like there is on an LCD. Maury Markowitz (talk) 16:33, 1 June 2009 (UTC)

For CRTs, at least in the US, a 19 is actually termed a 19V; the V standing for viewable angle. That means the diagonal measure of the visible content on the screen will be 19 inches. For LCDs and other flat technologies, globally, the diagonal measure is the measure of the viewable content. However for most of the rest of the world, the diagonal measure for CRTs was the diagonal of the tube not the screen so a 19V in the US would be something like a 20 or 21 inch set in Japan. While this can be misleading, the US measure can also be misleading. A 20V in the US would also be considered as a 21 inch in Japan as the difference between a 19V and a 20V is that the 20V has square corners where the 19V has rounded corners. The two tubes are exactly the same size, the difference is the extra 1/2 inch you get in each corner by squaring them out. Measuring the outside of the tube, as is done in Japan, eliminated that particular spec game.

Basic LCD concepts needs far more than sources and references

Some character comments that this section needs sources and references. The truth is that just adding sources and references won't improve it in the slightest. The basic problem with the section is that it does not clearly explain basic LCD concepts. I think there are people who make the idiotic comment on sources and references without finding out what is actually wrong with the section. RHB100 (talk) 21:23, 27 December 2013 (UTC)
