These test bars, throughout their evolutions-with the most recent occurring in 2002 to account for the HDTV switch-remain important in the television industry, as they allow engineers to adjust color schemes to correctly match what’s on the screen and modify accordingly.īut, thinking bigger picture, they also represent some of the first electronically produced graphics ever displayed on a screen-a pretty significant development in a world where graphics are basically everywhere. Hirsch of the technology company Hazeltine wrote a lengthy piece for the academic journal Advances in Electronics and Electron Physics in 1953, in which he described that company’s work on color television, including a discussion on the creation of color bars.) (To be clear, is evidence that Larky and Holmes have received the initial patent for this invention, though others were, without realizing it, competing with them around the same time. The color TV concept does predate Larky, but as an employee of early color television innovator RCA, he did develop some key patents on that front. Holmes) legitimately did receive the first patent for the color test pattern generator, which was granted in 1956 after being filed for in 1951. Times, which heavily covers the entertainment industry, as Larky (along with David D. ( Google Patents)Ĭlearly, this was a missed opportunity for the L.A. The first patent filing for the color pattern test generator. That was an experience that readers of the Times could have had in August of 2018, when an obituary for the 91-year-old Norbert David Larky (who generally went by his middle name) ran in its newspaper. This guy has a patent for inventing the color TV? And there’s not a reported obituary about his life? Dave had a distinguished career with 13 patents to his name, including the color television and the color test pattern. He earned his engineering and electronics degrees from Lehigh University and his master’s from Princeton University.
Let’s say you’re floating around an obituary page in a newspaper-let’s say the Los Angeles Times-and you see this line crop up:
