Editing Trinitron (section)

===Introduction, early models===
Officially introduced by Ibuka in April 1968, the original 12&nbsp;inch Trinitron (KV-1210) had a display quality that easily surpassed any commercial set in terms of brightness, color fidelity, and simplicity of operation.{{citation needed|date=December 2017}} The vertical wires in the aperture grille meant that the tube had to be nearly flat vertically; this gave it a unique cylindrical look.<ref name="stweb.peelschools.org">{{cite web |url=https://stweb.peelschools.org/pcsweb/pc_tut/06crtmon.htm |title=CRT Monitors |website=stweb.peelschools.org |url-status=dead |archive-url=https://web.archive.org/web/20200416205016/http://stweb.peelschools.org/pcsweb/pc_tut/06crtmon.htm |archive-date=2020-04-16}}</ref> It was also all [[Solid-state electronics|solid state]], with the exception of the picture tube itself, which allowed it to be much more compact and cool running than designs like GE's Porta-color. Some larger models such as the KV-1320UB for the [[United Kingdom]] market were initially fitted with 3AT2 valves for the [[extra high tension]] (high voltage) circuitry, before being redesigned as solid state in the early 70s.

Ibuka ended the press conference by claiming that 10,000 sets would be available by October, well beyond what engineering had told him was possible. Ibuka cajoled Yoshida to take over the effort of bringing the sets into production, and although Yoshida was furious at being put in charge of a task he felt was impossible, he finally accepted the assignment and successfully met the production goal.<ref name=s48>''Sony'', p. 48</ref> The KV-1210 was introduced in limited numbers in Japan in October as promised, and in the U.S. as the KV-1210U the following year.

Early color sets intended for the UK market had a PAL decoder that was different from those invented and licensed by [[Telefunken]] of [[Germany]], who invented the PAL color system. The decoder inside the UK-sold Sony color Trinitron sets, from the KV-1300UB to the KV-1330UB, had an [[NTSC]] decoder adapted for [[PAL]]. The decoder used a 64 microsecond delay line to store every other line, but instead of using the delay line to average out the phase of the current line and the previous line, it simply repeated the same line twice.<ref name=":0">{{cite web |title=45 Years Anniversary of Walter Bruch's PAL Color Television |url=https://www.radiomuseum.org/forum/45_years_anniversary_of_walter_bruchs_pal_color_television.html |website=www.radiomuseum.org}}</ref><ref name=":1">{{Cite web |date=2007-07-16 |title=Tech Notes: Colour TV |url=https://www.camerasunderwater.info/engineering/tv_stds/colortv.html |archive-url=https://web.archive.org/web/20070716064859/https://www.camerasunderwater.info/engineering/tv_stds/colortv.html |archive-date=2007-07-16  |access-date=2022-10-21 }}</ref> Any phase errors could then be compensated for by using a [[tint control]] knob on the front of the set, normally unneeded on a PAL set.
