The Trinitron design incorporates two unique features: the single-gun three-cathode picture tube, and the vertically aligned aperture grille. The single gun consists of a long-necked tube with a single electrode [dubious – discuss] at its base, flaring out into a horizontally-aligned rectangular shape with three rectangular cathodes inside ...
The FD Trinitron line featured key standard improvements over prior Trinitron designs including a finer pitch aperture grille, an electron gun with a greater focal length for corner focus, and an improved deflection yoke for color convergence. [1]
These were replaced about three months later by the KV 7010UA Trinitron tube. [1] The Sony KV 7010U CRT used the newly invented Trinitron gun combined with the Chromatron PDA wire grid instead of a shadow mask or aperture grill.
The first patented aperture grille televisions were manufactured under the Trinitron brand name. Fine vertical wires behind the front glass of the display screen separate the different colors of phosphors into strips. These wires are positioned such that an electron beam from one of three guns at the rear of the tube is only able to strike ...
The Trinitron screen was identical with its upright cylindrical shape due to its unique triple cathode single gun construction. In 1987, flat-screen CRTs were developed by Zenith for computer monitors, reducing reflections and helping increase image contrast and brightness.
Labelled sketch of in-line gun and slot mask in a color picture tube. Labelled sketch of delta gun and shadow mask in a color picture tube. In a conventional shadow mask television design the electron guns at the back of the tube are arranged in a triangle. They are individually focused, with some difficulty, so that the three beams meet at a ...
The other similar design is the Trinitron, which combined the vertical stripes of the beam-index and Chromatron tubes with a new single-gun three-beam cathode and an aperture grille instead of a shadow mask. The result was a design with the mechanical simplicity of the shadow mask design and the bright images of the beam-index system.
The OTs-14-4 "Groza-4" (Russian: ОЦ-14-4 "Гроза", lit. 'Storm') [1] is a Russian selective fire bullpup assault rifle chambered for the 9×39mm subsonic cartridge. It was developed in the 1990s at the TsKIB SOO (Central Design and Research Bureau of Sporting and Hunting Arms) in Tula, Russia.
