A handheld television is a portable device for watching television that usually uses a TFT LCD or OLED and CRT color display. Many of these devices resemble handheld transistor radios.

History[edit]

Sony Watchman

In the 1970s and early 1980s, Panasonic and Sinclair Research released the first TVs which were small enough to fit in a large pocket; called the Panasonic IC TV MODEL TR-001[1] and MTV-1. Since LCD technology was not yet mature at the time, the TV used a minuscule CRT which set the record for being the smallest CRT on a commercially marketed product.

Later in 1982, Sony released their first model - the FD-200, which was introduced as “Flat TV” later renamed after the nickname Watchman, a play on the word Walkman.[2] It had grayscale video at first. Several years later, a color model with an active-matrix LCD was released. Some smartphones integrate a television receiver, although Internet broadband video is far more common.

Since the switch-over to digital broadcasting, handheld TVs have reduced in size and improved in quality.[dubious ][citation needed] Portable TV was eventually brought to digital TV with DVB-H, although it didn't see much success. The major current manufacturers of DVB-T standard (common throughout Europe) handheld TVs are August International, ODYS and Xoro.

Hardware[edit]

These devices often have stereo 1⁄8 inch (3.5 mm) phono plugs for composite video-analog mono audio relay to serve them as composite monitors; also, some models have mono 3.5 mm jacks for the broadcast signal that is usually relayed via F connector or Belling-Lee connector on standard television models.

Some include HDMI, USB and SD ports.

Screen sizes vary from 1.3 to 5 inches (33 to 127 mm). Some handheld televisions also double as portable DVD players and USB personal video recorders.

Size[edit]

Portable televisions cannot fit in a pocket, but often run on batteries and include a cigarette lighter receptacle plug.

Pocket televisions fit in a pocket.

Wearable televisions sometimes are made in the form of a wristwatch.
