The collection primarily documents Lechner's research on high-definition television (HDTV) and his work on standards committees. Additionally, materials cover his work in other areas of television research, including video recorders, two-way cable TV services, TV tuners, and broadcast cameras.

Photographs and videocassettes in the collection depict thin film transistor liquid crystal display technology, color images of TFT-LCD screens, black and white images of an experimental model TFT-LCD system, and game testing on circular monitor for Mattel-96-Space War and Pong.

Three of Lechner's lab notebooks (1957-1959) can be found in Record group 26.
