'''Quattron'''是一個用於[[夏普]]製造的[[LCD電視]]的顯示技術的品牌名字。該技術在標準的[[RGB色彩模型|RGB]]（{{fontcolor|red|R}}{{fontcolor|green|G}}{{fontcolor|blue|B}}紅绿藍）色[[像素#子像素|子像素]]之外加上了[[黃色]]作為第四種顏色的子像素（{{fontcolor|red|R}}{{fontcolor|green|G}}{{fontcolor|blue|B}}{{fontcolor||yellow|Y}}紅绿藍黃），而Sharp聲稱這會使電視可顯示更多顏色，<ref>{{Cite web |url=http://asia.cnet.com/crave/2010/03/23/sharp-promises-quattron-tv-will-wow-/ |title="Sharp Promises Quattron TV Will Wow" CNET Asia, March 23, 2010 |accessdate=2013-08-23 |archive-date=2010-11-30 |archive-url=https://web.archive.org/web/20101130132851/http://asia.cnet.com/crave/2010/03/23/sharp-promises-quattron-tv-will-wow-/ |dead-url=no }}</ref><ref>{{Cite web |url=http://www.cnet.com.au/sharp-quattron-lc-46le820m-339304449.htm |title="Sharp Quattron LC-46LE820M" review by Philip Wong, 16 July 2010, CNET Australia |accessdate=2013-08-23 |archive-date=2010-08-31 |archive-url=https://web.archive.org/web/20100831082027/http://www.cnet.com.au/sharp-quattron-lc-46le820m-339304449.htm |dead-url=no }}</ref>並可能更接近地模擬了人腦處理顏色的方法。<ref name=gadgety>{{cite web |url=http://gadgetynews.com/sharp-aquos-quattron-tv-brings-in-yellow-fourth-pixel-rgby/ |title=Sharp Aquos Quattron TV Brings in Yellow Fourth Pixel – RGBY |author=Jay Garrett |date=2010-03-10 |publisher=GadgetyNews.com |accessdate=2010-04-13 |archive-date=2010-03-22 |archive-url=https://web.archive.org/web/20100322235206/http://gadgetynews.com/sharp-aquos-quattron-tv-brings-in-yellow-fourth-pixel-rgby/ |dead-url=no }}</ref><ref>{{cite news | url=http://online.wsj.com/article/SB10001424052748704423204575016401004860156.html | work=The Wall Street Journal | first=Daisuke | last=Wakabayashi | title=Sharp Expands Its TV Color Palette | date=26 January 2010 | accessdate=2013-08-23 | archive-date=2013-11-11 | archive-url=https://web.archive.org/web/20131111015453/http://online.wsj.com/article/SB10001424052748704423204575016401004860156.html | dead-url=no }}</ref>這種屏幕是多原色屏幕的其中一種形式，市而上尚有其他不同的種類被同步開發中。<ref>{{Cite web |url=http://www.genoacolor.com/solutions.asp?pageId=16 |title=parallel LCD design from Genoa Color Technologies website |accessdate=2013-08-23 |archive-date=2012-01-08 |archive-url=https://web.archive.org/web/20120108174126/http://www.genoacolor.com/solutions.asp?pageId=16 |dead-url=no }}</ref><ref>{{Cite web |url=http://www.genoacolor.com/Media/DBImages/IDMC07_AUO_manuscript_0515.pdf |title=multi-primary color display research from GCT |accessdate=2013-08-23 |archive-date=2012-04-25 |archive-url=https://web.archive.org/web/20120425091830/http://www.genoacolor.com/Media/DBImages/IDMC07_AUO_manuscript_0515.pdf |dead-url=no }}</ref>

==反響==
根據影像校正儀器生產商DisplayMate Techologies總裁雷蒙德索内拉在“MaximumPC”雜誌所刊印的分析報告所指，Sharp的Quattron技術並未有能力顯示多於標準[[RGB色彩空間]]的顏色。他認為，由於[[內容供應商]]透過現成工業標準的色彩空間向用戶提供內容，所以市面上並沒有能利用到第四色彩頻道的內容。因此他認為任何所顯示的「額外」顏色均需要經由電視機以影像處理方法創造出來，以致所顯示的顏色被誇張化而失真。<ref>{{cite web|title=Maybe Sharp Should've Consulted Mr. Spock Instead|url=http://dl.maximumpc.com/Archives/MPC0710-web.pdf|publisher=Maximum PC magazine|accessdate=19 August 2010|author=Dr. Raymond Soneira|page=51|date=July 2010|archive-url=https://web.archive.org/web/20121002194738/http://dl.maximumpc.com/Archives/MPC0710-web.pdf|archive-date=2012-10-02|dead-url=yes}}</ref>
