A Handheld television is a portable device that usually uses a TFT LCD or OLED color display. Many of these devices resemble handheld transistor radios.
History[edit]
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 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 the first model of the Watchman; a pun on Walkman. 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. 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 (3.2 mm) phono plugs for composite video~analog mono audio relay to serve them as composite monitors; also, some models have mono 1/8" jacks for the broadcast signal that is usually relayed via F 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 PVR.
Size[edit]
Portable TVs cannot fit in your pocket, but often run on batteries and include a cigarette lighter receptacle plug.
Pocket TVs fit in a pocket.
Wearable TVs sometimes are made in the form of a wristwatch.
