LCD-Direct-View Flat Panel Television
Why so many bet on LCD-Direct-View as a rapidly emerging challenger to plasma.
But see a special warning for the obsessive!Marriott International, Inc. is going to begin installing some 50,000 LG-made 32-inch LCD-Direct-View flat-panel HDTVs over the next four years in the rooms of various JW Marriott, Marriott, and Renaissance hotel locations. The new HDTVs will include a special desk-level connectivity panel with lots of AC outlets and plenty of input connections for portable electronic essentials, such as laptops, PDAs, DVD players, MP3 players, camcorders, and video game players.
A smart move - this will introduce many to the amazing world of lcd flat panel television.
LCD-Direct-View Flat Panel (if you consider up to 4 inches or so, flat.) LCD = Liquid-Crystal Diode. The direct view LCD consists of a panel of viscous liquid sandwiched in plastic. (I think my mom made that for lunch sometimes.) The liquid is driven by a network of transistors that control individual pixels. A pixel is a tiny dot of light or color. Actually, every pixel has three sub-pixels: one each for red, green and blue. When a transistor delivers an electrical charge, the crystals 'untwist' to an exact degree to filter light generated by a lamp behind the screen. (There will be a test on this.)
LCD Direct-View Flat Panel PLUSSES. Thin, lighter and sleeker than CRTs.
Shallow depth.
Décor friendly.
LCDs need no convergence (alignment of the colors so they sit on top of each other).
Immune from "burn-in," so there's never any harm or worry from videogames if left on too long. Or network logos down there on the corner of the screen.
No speaker shielding necessary like with CRTs.
No altitude limits like Plasma.
Would you believe we are on the SEVENTH generation of LCD panels?That’s better and better and better and better and better and better. That’s not bad!
Less power consumption than CRT..
Bright image.
LCD-Direct-View Flat Panel MINUSES.
Some limitation in viewing angle and contrast ratio.
Picture quality doesn't equal the best available from the very finest tube TVs, specifically in the areas of contrast ratio, black level, smooth motion. (Look for LCD panels with single digit ‘response times’)
Angle of view
Warning for the obsessive:
Dead pixels are the result of flaws in the glass sheets that go into displays. Inevitable glitches in the manufacturing process mean that some pixels don't illuminate properly--or at all. Manufacturers can avoid most defects by scrapping bad sections of a glass sheet, but a few bad pixels usually crop up in other areas.
Here’s one manufacturer’s word on the subject: since such things are subject to review and change, we won’t embarrass the source:
"During the manufacturing process, it is not uncommon for one or more pixels to be fixed in an unchanging state. The visible result is a fixed pixel that appears as an extremely tiny dark or bright discolored spot. In almost every case, these fixed pixels are hard to notice and do not detract from the display quality or usability. A display with 1 to 5 fixed pixels is within the industry standards, and is therefore considered an acceptable display. LCD screens that do not meet this industry standard are rarely passed on from the point of manufacturing. If you notice more than six (6) fixed pixels on your display, or if there are several fixed pixels in a small area of the screen, contact XXX Technical Support."
OPINION:The LCD-Direct-View Flat Panel display is a fast growing segment of display technology, one which manufacturers hope will displace plasma TVs for customers wanting thin displays. Price erosion will continue for some years to come!
Mister Weather called.
A friend called. He's been on TV for over 20 years. He wondered if he should get HD from his cable provider for his HD ready (relatively new set.) I said yes, yes, yes. He said he didn't like the way his HD TV was showing standard definition broadcasts because the 4:3 proportion only filled part of the wider screen and he didn't like the stretch modes. I'm with him there. I don't like the fattening or the shrinkage.
Without seeing them ALL, I believe that the different manufacturers have their own schemes for filling the screen with pictures that don't really fit. For example, these, from a highly regarded
Philips 32PF9996 LCD Flatscreen
Aspect selections include Automatic, which fills the screen with all sources except 720p; Super Zoom, which stretches the sides of 4:3 sources to fill the screen; 4:3, which displays 4:3 sources with black bars to either side; Movie Expand 14:9, which zooms 14:9 letterboxed content to fit screen height; Movie Expand 16:9, which zooms letterboxed content to fill the screen; 16:9 Subtitle, which shifts Movie Expand 16:9 upward so that subtitles are visible; and Wide-screen, which displays 16:9 sources properly. But, you can't change aspects with HDTV sources, and only two options (4:3 and Wide-screen) are available for 480p sources (think DVD.)
Incidentally, this set has the ambi-lighting which can 'match' screen color with backlights. Or be their version of white, or blue, or red - or off. I'd have to live with it to know if this was something I'd want. I do know your eyes prefer SOME lighting in the TV's room.
If you buy this one, you will need to be sure you have a PROGRESSIVE SCAN DVD player or you'll see artifacts - as the set lacks what's called 2:3 (aka 3:2) pulldown detection: digital technology developed to accurately convert and display content originally on celluloid film, which runs at 24 frames per second (fps) compared to the 30fps rate of television.
Users report loving the set with very high marks, though the database is fairly small so far. 720P sources don't fill the entire screen.

The SONY BRAVIA XBRs are worthy. Check these if in the market for an LCD flatscreen.
