Mini Flat Screen TV

Thursday, July 22nd, 2010

Mini flat screen TVs provide all the advantages of conventional flat screen televisions and an additional one as well.

 

There are plenty of reasons to switch to one of new TVs. They provide superior motion resolution and wider viewing angles. They offer very little glare off a screen, even when the room is very bright. They are portable and very light weight and cost less than 300 US dollars. You can easily mount it on your living room wall or keep it in the smallest of space. One of the most compelling reasons is reduction in area needed to house the TV. Old TV sets took away a large portion of the 'den'. By hanging it on a wall you improve the quality of the images. Most modern TVs are built to be at optimum quality when wall mounted.

 

Presently only LCD or Liquid Crystal Display technology is used in making mini flat screen TVs. This uses pixels made of a layer of aligned molecules flanked by two electrodes. Two polarizing filters are placed perpendicular to each other so that the other blocks light traveling past one filter. Control of the voltage given to a pixel allows controlling the amount of the light that travels through. This gives varying shades of the same color. Pixels are separated into three parts that are red, green or blue to produce color. Each part is separately controlled and work independent of the other two.

 

Many mini flat screen TVs can be connected to personal computers or laptops and in this dual usage can save money for the users. They can help reduce the cost of electricity as they consume less power comparative to conventional monitors of same size. They can on average be used for as much as 60000 hours. They can easily be connected and powered by a car battery, so that passengers can enjoy their favorite show even while traveling.

 

Mini TVs have their own disadvantages. Because of the portability, it is easy for thieves to make off with them. More cons are found in the technological aspects. 'Burn In' - the damage to a pixel making it to stay in either on or off state is a major issue. This decreases the contrast and reduces the picture quality. Poor scaling result in after affects like jagged edges and conflicting details. Scaling compounds the effects of poor quality of an incoming signal.

 

Mini Flat Screen TV has a inherent delay that cannot be overcome. This causes motion blur due to slow response time. The more popular brands have minimized the artifacting and artifacting is not noticeable in minis.

 

LCD display uses a back light that shines through the panels. LCD TVs tend to experience problems in getting the 'full black' color and resembles a very dark gray. While many LCDs can double up as either computer monitor or a Mini TV, it is usually has very poor video display when used as a display for PCs.

 

Consider the display contrast ratio, aspect ratio, resolution, dot pitch, brightness, response time and color reproduction when you are deciding on buying a mini flat screen TV.

 

How to choose the best Flat screen TV

Choosing the right technology

 

Plasma and LCD TVs look the same, but they are not. Some features or options don't differ a lot, but these are the major differences:

 

Size

 

If you arfe looking for an extra large TV, go for a plasma. Plasma TVs are the current size champions, particularly when comparing TVs that consumers can easily purchase. LCDs are catching up in size with their developing technology, however, and may surpass Plasmas in the near future. This may be due to difficulties in producing glass large enough for larger plasmas.

 

Burn-ins

 

With the latest plasma technology, this is less of an issue than ever before. The Pixel Orbitor, for example, is a method of reducing burn-in used by plasma manufacturers. It requires no additional programing from the end user as some older burn-in prevention techniques did.

Note: If you plan to use a plasma for gaming, some games with permanent 'dashboards' may still cause some burn-in. If you will be using the television for display use only, go for an LCD. Plasmas are more likely to get burned-in pixels.

 

Miscellaneous

 

- LCD TVs are far less fragile than plasmas. This is also an advantage when the tv set has to be shipped or moved to a different location.

 

- LCD TVs are also much easier to install than plasma TVs.

 

- LCD TVs have a better performance at high altitudes.

 

- LCD TVs are often cheaper than plasma TVs. The difference in pricing is getting smaller, however.

 

Ofcourse, all this information is available all over the web. For a detailed comparison sheet, I recommend using Wikipedia's comparison sheet.

 

Flat Screen TV comparison, don't get it wrong

 

If you have made a choice between plasma and LCD (I'll name it Flat screen TV from now on), you can pick a TV of your choice. Flat screen TV comparison will able you to find out exactly what you want and what'll fit the budget.

The following brands are being considered as the best manufacturers of Flat screen TVs:

 

- Hitachi

 

- Panasonic

 

- Philips

 

- Pioneer

 

- Samsung

 

If you are looking for a product with outstanding quality, we recommend choosing one of these brands.

 

Features

 

Different Flat screen TVs have different features. Most of these features look the same, but there are a couple of unique features as well:

 

- Ambilight

 

- HD ready or not?

 

- Picture in Picture

 

There are lots of comparison website available, but you will have to know how to use them. Filter the models by brand, price and features and the choice will be a lot easier.
