So what do you need to know before you get one?
How does an LCD TV work?
Liquid crystal displays have been around for a long time: the clock on your VCR, the display in your microwave, the clock in your room, etc. LCD screen has a great advantage: it has low power consumption and can be converted into almost any shape, such as picture frame LCD TV. The LCD television screen consists of two transparent polarized panels and a liquid crystal solution sandwiched in between. The front glass layer of the screen is etched on the inner surface in a pattern to form a template for the liquid crystal layer. Liquid crystals are shaped like rods that bend light when electricity is applied to them, so light cannot pass through them. Each crystal acts as an on and off switch, either allowing light to pass through or blocking it, the clear and dark pattern formed by the switching crystals forms the image you see.
What do I need to know before buying an LCD TV?
Unlike older tube TVs, there are important things to consider when shopping for an LCD TV. LCDs involve computer technology and computer technology involves microprocessors, software, etc. These are things that can make your shopping experience a success. I have revised and simplified the shopping experience; Below is a list of things to know before you make your purchase, as well as tips. It is very important to know what is listed below because if it looks good in the store, it may not look good in your living room.
First things first, how much viewing space do you have in your home for the TV you want?
Recommended
For 20″ to 27″ TVs, it should be between 2.5 and 5 feet from the screen.
For 32″ to 37″ TVs, it should be 6 to 8 feet from the screen.
For 42″ to 46″ TVs, it should be 10 to 14 feet from the screen.
For 50″ to 60″ TVs, it should be 12 to 16 feet from the screen.
Response/update time
This is the time it takes for each image frame to update on the screen. This is very important because if it is slow you will see a poor quality image depending on what you are seeing. Make sure you get something in the range of 5 ms or less. Even if your movies and sports games look great, your kids’ video games may not. I would recommend getting the fastest response time you can find for a decent price.
connections
Don’t be fooled by the “computer ready” slogans, if you want a clear picture from the computer you will connect to the TV, make sure the connection is DVI, many TVs come with computer (VGA) connections but not DVI type . Connection.
Other Basic Connections: HDMI (High-Definition Multimedia Interface) similar to DVI, RF In, Component (Y/Pb/Pr), S-Video In, A/V In, USB 2.0, Premium Audio, Headphone Jack .
image clarity
width units : tall units
Normally 16:9 is for HDTV, most programs are broadcast in 4:3 ratio. Make sure you get 16:9 or you’ll be disappointed.
1080p, 1080i or 720p?
Let me give you the answer HD movies are out and Blue ray is in, Blue ray works at 1080p at the end of the conversation. If you still insist on going deeper, read the next paragraph.
1080p means the image resolution is 1920 vertical pixels by 1080 horizontal pixels, and the “p” stands for progressive scan. Progressive scan offers a smoother image as horizontal or vertical lines are scanned. This is Blu Ray and true HD quality.
1080i means that the image resolution is 1920 vertical pixels by 1080 horizontal pixels interlaced. Interleaved refers to the scanning method in which each odd line is scanned one followed by a second scan of even lines. This is not smooth like 1080p.
720p is the same concept as 1080p except the resolution is 1280 pixels vertical by 720 pixels progressive horizontal. This is normal cable TV resolution.
