About: Porta-Color

An Entity of Type: WikicatVacuumTubeDisplays, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

General Electric's Porta-Color was the first "portable" color television introduced in the United States in 1966. The Porta-Color set introduced a new variation of the shadow mask display tube. It had the electron guns arranged in an in-line configuration, rather than RCA's delta arrangement. The main benefit of the in-line gun arrangement is that it simplified the convergence process, and did not become easily misaligned when moved, thus making true portability possible. There were many variations of this set produced from its introduction in 1966 until 1978, all using GE's Compactron vacuum tubes (valves).

  • General Electric's Porta-Color was the first "portable" color television introduced in the United States in 1966. The Porta-Color set introduced a new variation of the shadow mask display tube. It had the electron guns arranged in an in-line configuration, rather than RCA's delta arrangement. The main benefit of the in-line gun arrangement is that it simplified the convergence process, and did not become easily misaligned when moved, thus making true portability possible. There were many variations of this set produced from its introduction in 1966 until 1978, all using GE's Compactron vacuum tubes (valves). The name has been variously written, even in GE's literature, as "Porta Color", "Porta-Color" and "Porta-color". The name may also refer to the specific television model, or less commonly, the style of television tube it used. (en)
  • Il Porta-Color, noto anche con i nomi Portacolor o Porta color, fu il primo televisore portatile a colori introdotto nel mercato italiano. Fu prodotto nel 1967 dalla CGE, utilizzando un circuito completamente a valvole. Inoltre fu il primo anche ad utilizzare un cinescopio con disposizione dei cannoni In-line (in linea) anche se i fosfori erano disposti a Delta (triadi). Le uniche trasmissioni che si potevano ricevere a colori in quel periodo, erano Studio Koper Capodistria (solo in Friuli-Venezia Giulia e nelle zone limitrofe di Milano), e Radio Televisione Svizzera Italiana. Il sistema di decodifica del colore era il PAL semplice, nel quale (a differenza del PAL tradizionale) la tinta era regolabile tramite un comando supplementare di regolazione della tinta, presente sull'apparecchio. Ad oggi se ne contano pochissimi esemplari sopravvissuti. (it)
