Answer
There are many technologies emerging in display devices like TVs. Every technology excels in particular feature of display and has particular method of display. Different technologies used in TVs are:
LCD TV:
LCD (Liquid Crystal Display) televisions are thinner and lighter and provide much sharper and clearer picture than CRTs of similar size. They are ideally used for cell phone displays, computer monitors, and to view still images.
· LCD TVs have a flat screen so there will be no picture distortion and don't have screen "burn in" like curved tube TVs.
· In general, LCD viewing angle is 175 degrees. The picture can be viewed 87 degrees from each side.
· LCD TVs are very economical to use and screens less than 35 are fairly inexpensive.
· LCD TVs are backlit and blocks outside light. So, they are suitable for natural lighting situations.
· Most LCD TVs have a half lifespan (50% of original brightness) of over 30,000 hours (16 years of viewing at 6 hours per day).
LCD sizes generally range from 13 to 65 but some manufacturer will offer up to 100 sizes.
Plasma TV:
A Plasma Display Panel (PDP) is a flat panel display used in large TV displays. They have better and accurate color generation than LCDs, and with far display, wider viewing angles, and do not experience degradation at high angles compared to LCD. Plasma displays are ideal for viewing motion video in large displays.
· Plasma screen sizes generally ranges from 32 to 84 but some offer screen sizes up to 100.
· Plasma pixel, technology provides a brighter picture with more contrast between the blacks and whites than standard TV.
· In general, plasma TVs viewing angle is 160 to 180 degrees and picture can be viewed from any angle.
· On an average, Plasma TVs have a half lifespan (50% of brightness) of 50,000 to 70,000 hours (20 years of viewing 6 hours a day to 50,000 hours).
Some plasma TVs are provided with upgradeable video cards that helps to match with future technology.
HDTV:
HDTV or High-Definition Television is a digital television broadcasting system offering a higher resolution compared to regular television systems. HDTV is digitally broadcast unlike earlier analog broadcasting, because digital television (DTV) signals require reduced bandwidth because of digital video compression.
HDTV will not have standard TV problems, like low quality sharpness, troubles with brightness or contrast, spots, other visual, or audio imperfections, problems like double images (ghosting), and weak signals. HD television provides clearer pictures with excellent sound quality, a wider viewing screen and up-to-date scanning. HDTV will provide more and superior channels provided by regular satellite or cable television with theater system experience.
LED TV:
LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for back lighting, instead of using the fluorescent lights (as it creates more black spots). They are ideally used for low-energy indicators, as substitutes for traditional light sources in general lighting and automotive lighting.
· LED TV currently costs more than a standard LCD or plasma TV.
· LED TV has got great looks and very easy to Install.
· Edge-lit LED television will consume 30-40% of less power than LCD or plasma TV. But backlit LEDs will consume more power.
· Brighter picture can be viewed with LED television compared to a standard LCD TV.
· LED TV that is backlit, with local dimming and RGB LEDs, will have an enhanced picture and better contrast ratio and colour accuracy compared to standard LCD TV.
It has a long lasting life and also eco friendly.
OLED TVs:
OLED (Organic Light Emitting Diode) TVs depend on light emitting polymer technology. Its features including,
· In OLED TVs, there is no need for backlights or extra heaters or coolers, so there is less power consumption.
· As OLED materials has the capacity to support full spectrum of visible light, so there will be higher contrast and it has high-speed refresh rates.
· OLEDs are much faster than LCDs. Fast motion and quick eye movement pictures are more realistic. And OLED TVs will make virtual images to look realistic and can be viewed easily for longer periods.
· It has larger viewing angle and for near-eye applications, it provides more pleasant viewing without distortion.
One disadvantage with OLED TVs is the limited lifespan of the organic materials used in its manufacturing. In addition, blue light degrades quickly with a lifespan of 14,000 hours (when used 8 hours per day for five years) on flat-panel displays.
Before purchasing a television, know the difference between each technology and purchase the one, which has your desired features and suits your budget.

Have You Ever Been In Contact With A Ghost?
Q. Me and a close friend of mine have an interest in the paranormal. There's an old cemetary (dates back to the early 1700's) that we sometimes hang out in at night.
We've had a few experiences that I can't really explain while we were there.
One time we hung out in there for about 45 minutes at around midnight just taking sound recordings and walking around the area. My friend walked over to an area and said "wow, it's REALLY cold over here, Saige." About a second later we heard "Saige!" in a little girls voice. It sounded very happy.
I turned to ask him if he heard anything when he said "Uh, did you hear that?"
Another time we were there with anothe friend of ours at around 11:00 at night. There was a dark shadow in the shape of a human near one of the graves. It was just a bit darker than the night and walked off into the other graves when we took a few steps towards it.
Do you have any stories of encounters?
Maybe I should add that when the voice said "Saige" I turned to ask my friend if he heard it to and before I got a chance to he said "did you hear something say Saige?"

Answer
I have had many encounters in my life time. The first one was my Dad's mother. She died when he was only 7 years old. I was going through a bitter divorce when my boys were 2 and 4 years old. It was in the summer, I was laying on the couch watching tv and fell asleep. I woke up to the sound of static on the tv, the station went off the air for the night. All of a sudden there was this damp cold chill. In the doorway of my babies room was this figure of a woman, long white dress, dark hair in an up sweep. I couldn't see her face tho. All she said a few times was "it will be alright". Then, she was gone as fast as she came. When she left, the cold chill left too. When I told my dad what happened that night, he knew it was his mother. She had 9 kids and would say to them when things went wrong, it will be alright. The second encounter was right after my mother died. I had encounters with her. Fist one I thought I felt a hand being placed on my shoulder and heard my name being called. I turned around and no one was there. The second encounter was when my dad was leaving with a woman he just met. My mom had been gone for 2 years and he met another woman. As they were leaving that night, I had a cover to a frying pan on the counter. It started going back and forth, faster and faster. All I could say was "okay mom, stop it now, he's happy, that's all that matters so stop it. Justl like that, it stopped. Every once in a while I get a feeling as if someone is leaning or sitting on the edge of my bed. I lay on my right side and the feeling is always behind me. At first I thought I was one cf my cats as they both like to lay on my bed with me. When I turned around to see if it was them there was no one there. I came to the conclusion that it's my mom checking in with me. Now, I just pat the spot where I felt that and say everything is fine mom. I had a few encounters with my husband who passed away 9 years ago. From things being moved around the house, to shadows in the hallway that went through my son's bedroom door to an image of a man walking up the road while I was at my husband's grave. I had taken a picture of my son and his girlfriend at New Years Eve, almost a year after my husband died. On the wall is a what I thought was spot of light from the flash. The longer I looked at that picture, the more I saw an image of a man's face. I did send that pic to a few online paranormal places and was told that there is an image in that picture. There were even times when I would hear crying or whimpering coming from my bedroom after my husband died. I was told by a few paranormal web sites that it was my husband crying. Somthing he did a lot of when he was alive as he was such a sensative person. I lived in a house that was built in 1764 and would see a shadowy figure come out of the bathroom, on the second floor heading into my son's room. I would be walking up the stairs and got about half way and would see a shadow of a man. This was almost every day. I asked the lady who lived next door, as the house was converted into a duplex. She said it was the original owner of the house and that he wouldn't hurt anyone. I was painting the kitchen one night and saw a man peak around the corner at me. He was in the livingroom looking threw the doorway that led into the kitchen. It looked just like the shadowy figure that I would see upstairs. I went into the livingroom to look and no one was there. I moved out of there and live down the street now from that house. Every time I go bye, I think of Eli and his visits that he paid to me. With each encounter, there was always a very damp, cold chill in the air. As soon as the apparition was gone, so was the cold chill. Many of you may think I'm a raving nut case, I'm sure. I have had other people with me when I had some of these encounters. I hope my stories helped you more in your questions. Happy ghost hunting!
