The first and most obvious advantage of a portable television set is that it is in fact portable. You can carry it with you wherever you go and most can fit inside the pockets easily.
Another benefit is the fact that you can still connect the portable TV to your home entertainment system such as the DVD player and still enjoy good movies.
Modern portable TVs come with plenty of features that are found in larger TV sets. An example is the Nicam stereo sound.
The smaller size of the TV also means that they use less power. While some will come with rechargeable batteries, connecting to the power source will consume less than the larger TVs.
Some models come with in built DVD players. They are cheaper compared to buying individual units.
There is also the saving of space. You do not have to worry about where you are going to place the TV. You can put it in the kitchen and enjoy good entertainment as you cook or you can simply reach for it when you are still in bed.
Portable TVs do not have glare. This is thanks to the matte finish. Normal CRT or LCD TVs have glass which produces a lot of glare. With a portable TV you can comfortably watch what is on screen even with the windows fully open.
There are some drawbacks to having a portable TV. The first is the size of the screen. If you are used to larger displays, a portable TV can be frustrating.
There can be a bit of blurring of the images on the portable TV. This happens when the images are moving too fast to be rendered.
You also need to look at the screen directly to be able to view the best quality images. If you move away from the screen, the quality of the image drops.
If you want to connect the portable TV to a digital decoder, there is the problem that the decoder will need a power supply to be able to run. This negates the portability of the portable TV.
