特丽珑，又译特丽霓虹，香港有时译作新力单枪，是日本索尼公司为其采用特殊结构的彩色阴极射线管（CRT）注册的商标，被用于制造彩色电视、彩色监视器和彩色电脑监视器，于1967年开发成功；到2007年由于液晶显像技术的冲击，而在全球范围停产。特丽霓虹阴极映像管因为几大优势被认为是市面上性能最好的彩色显象管之一，其时在广播专业领域和专业电脑绘图领域具有独占鳌头的市占率。索尼公司自己制造采用特丽珑管的显像设备，同时也把此管成品卖给其他专业厂家，这些厂家可以采用自己的电路设计驱动特丽珑管（例如德国根德(Grundig)部分型号彩电，和电脑监视器领域的EIZO Flexscan系列，都属于此种情况）。

Trinitron is Sony's brand name for its line of aperture-grille-based CRTs used in television sets and computer displays. One of the first truly new television systems to enter the market since the 1950s, the Trinitron was announced in 1968 to wide acclaim for its bright images, about 25% brighter than common shadow mask televisions of the same era. Constant improvement in the basic technology and attention to overall quality allowed Sony to charge a premium for Trinitron devices into the 1990s.
