{{Unreferenced|date=June 2010}}A handheld television is a portable device for watching television that usually uses a TFT LCD or OLED color display. Many of these devices resemble handheld transistor radios.

History

(File:Sony watchman fd210.jpg|thumb|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 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.{{dubious|reason=See talk page|date=August 2018}}{{cn|date=August 2018}} 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

Some include HDMI, USB and SD ports.Screen sizes vary from {{convert|1.3|to|5|in}}. Some handheld televisions also double as portable DVD players and USB personal video recorders.
