2025 Convention - Matthew D'Asaro

The Sony Chromatron: Snatching success from the jaws of failure - A brief (pre) history of the Sony Trinitron

In this presentation Matthew D'Asaro will be describing the history behind the museum's latest exhibit, a working Sony Chromatron TV. The Chromatron, originally invented by Nobel laureate and Manhattan Project physicist Ernest Lawrence, is an alternative color CRT design. Initially worked on by Paramount Pictures, the rights were bought in 1961 by Sony who planned to mass produce it. The effort nearly bankrupted Sony, but ultimately lead to the development of the wildly successful Trinitron. This history will be explored in more depth along with internal photographs and details of the Chromatron on display at the museum.
