Abstract
An improved color picture tube according to the invention includes a faceplate panel having a cathodoluminescent screen thereon. A low expansion color-selection electrode is mounted in the faceplate panel by a support structure including a bimetal element. The support structure is responsive to changes in temperature of the faceplate panel and moves the color selection electrode relative to the screen.
