How Do Portable TVs Work?

Most portable TVs work by receiving digital signals from television station towers. In order for your portable television to receive programming, it must first tune in to the television station’s broadcast frequency.

Because portable TVs are designed to use on-the-go, they do not need to stay plugged into a wall outlet in order to work. Portable TVs can be powered by a car adapter, AC adapter or batteries.

Although sprawling out on the living room sofa in front of a big screen is still the preferred method of TV viewing for many, portable television can allow customers to enjoy their favorite programming even when they are far away from the comforts of home (and sofa). A portable TV works wonderfully in a number of situations, whether you’re tailgating or cooped up in the car on a long road trip.

The size of the display screen on most portable TVs ranges from 5 to 10 inches, making them ideal for travel but not so ideal for home viewing. Portable TVs are designed to offer viewers convenience and flexibility, but they are not designed to provide the most comfortable or high-quality viewing experience. In other words, you probably don’t want to invite all of your friends over to watch the Super Bowl on your portable TV. But, if you happen to be camping in an RV over Super Bowl weekend, a portable TV could be a lifesaver.

How good is the reception on a portable TV?

The reception can vary with model and manufacturer so it’s best to consult the site or call for information specific to the brand you’re looking to purchase. The quality of a portable TV’s reception is largely dependent on its capacity to demodulate or decode signals, translating them to the portable screen.

What’s the screen like on a portable TV?

In the case of portable digital TVs, liquid crystal displays (LCDs) are used. If you have ever seen older handheld gaming consoles or GPS units in cars, you are familiar with these screens. An electrical current produces images by stimulating the glass panes while a light filters through the crystals. As you can imagine, this requires a bit of power so, as we stated earlier, spare batteries and AC adapters are a must.

Are there alternatives to portable TV?

Yes. Many different television services offer second screen experiences through free apps that work in conjunction with their DVRs.
