do you mean are there differences between the displays on a "lcd television" and "lcd computer monitor" ?
the best answer i can offer up is "maybe".
-computer lcd monitors are typically available in a variety of resolutions. quite a few of these surpass typical lcd television resolutions.
-computer lcd monitors also usually have smaller pixels which make them look sharper than televisions.
-lcd televisions are typically available in much larger sizes than lcd computer monitors. monitors usually top out at around 30". however, the televisions maintain the same 1920x1080 (if a 1080p tv) resolution no matter what physical size the display is. this means the larger you go the less sharp everything looks.
-some lcd televisions have 4 pixel colors instead of 3. i think it is samsung who is experimenting with a tv on the market right now.
-if you are comparing led (and not ccfl) backlighting then some televisions are not edge-lit and instead have the leds arranged in a grid behind the lcd screen. this can give you better contrast. i know of at least one model that has this feature.
as far as a subjective review... i've always found lcd monitors to display text much better than lcd televisions even accounting for the size increase in pixels. some people say there is a difference in the arrangement of the pixels but to date i have not found any source to prove or disprove this rumor.
if you're looking for a suggestion on what to buy then fill out a monitor advice request sheet which you can find by looking at a few other "what monitor should i buy" posts. or just list all the details here like budget, size, resolution, what you want to use it for, connection requirements, etcetera.
tube televisions/monitors can also have a "flat" front to them but i don't think this is what you are refering to (as technically there isn't a panel on them just glass and a filter) so i won't provide any information on them as it most likely doesnt apply.
when it comes to flat panel televisions there are two types: plasma and lcd.
plasma displays were big a few years ago but they are starting to be phased out. they can offer better contrast than lcd televisions but had trouble when it came to long-term reliability.
lcd monitors can be further broken down into two different catagories. ones which are backlit by ccfl and ones that are backlit by leds. both of these subtypes use an lcd screen, the only difference is the style of backlight they use.
tn, va, ips are all types of liquid crystal display (lcd) technology. that said, there could be small variations between different brands of televisions. i know that at least one brand is experimenting by adding a 4th color to their pixel arrangements, and i'm sure others have their own little experiments as well.
short answer: the general technology is the same but there might be subtle variations between different brands. led and ccfl are backlighting and are not tied to panel type.
