cathode ray tube
cathode ray tube
Danh từ
Số nhiều: cathode ray tubes
This term refers to the bulky vacuum tube technology that defined television and computer monitors before the advent of flat-panel displays like LCD or OLED. It carries a strong connotation of obsolescence and retro-technology, often evoking images of heavy, deep-backed screens from the mid-to-late 20th century.
In technical discourse, it is frequently abbreviated as CRT. While the full phrase is used in formal engineering or historical contexts, the abbreviation is more common in consumer electronics and vintage computing circles.
