Quick Summary
The Trinitron was a type of color television picture tube developed by Sony Corporation in the late 1960s. It replaced the traditional shadow mask with an aperture grille, which featured vertical slots instead of holes. This innovation allowed more electrons to reach the phosphors on the screen, resulting in a brighter picture. The Trinitron's design was a significant improvement in television display technology, contributing to Sony's success as an electronics giant.12
