|The technologies used in the different parts of cathode ray tubes are largely based on the wide range of products offered by Imphy Ugine Precision.|
CRT's, a thermal compensation (TC) system is used to avoid image quality
problems with the expansion of the shadow mask as the operating
temperature of the tube rises (doming, landing, etc.). In some cases,
trimetal (SS / InvarŪ / SS, welded edge to edge) is used to produce the TC
spring. Trimetal enables cost effective part stamping (two parts per
stroke, less scrap), part simplification (no extra spring). Furthermore
this part has a shorter reaction time and its deflection, in the same
direction as the frame / shadow mask is better matched then in some cases,
where an R80 bimetal is used with an SS spring.
Our expertise and experience in the field of cathode ray tubes and projection systems place us in a strong position as regards emerging display technologies. The components used in these different systems draw heavily on the wide range of products proposed by Imphy Alloys.
