RESEARCH AND DEVELOPMENT OF TWO-COLOR DIRECT VIEW STORAGE TUBE WITH SELECTIVE ERASURE.
Abstract
A direct view storage tube is being developed which is capable of displaying stored information in either of two colors or in intermediate hues, and selectively erasing that information. The viewing screen consists of two phosphors. One occupies small areas in register with the storage-mask holes, while the other occupies areas surrounding the first. Color tubes were constructed with 150-line storage mesh. Data on these tubes show the green phosphor efficiency was good, but the red phosphor efficiency was exceptionally low. Target performance was normal and registration excellent, although the uniformity of color shift was affected by a moire effect. A higher-count collector mesh has been ordered to reduce this color moire effect. Investigation continues, with promising results, on methods for fabricating a color screen having a phosphor dot surrounded by a solid field of the second phosphor for improved light output and color uniformity.
