Abstract

PURPOSE:To free observers from fatigue and inconvenience by choosing the body colors of fluorescent blocks, composed of more than two different sorts in the emitting color, formed in a certain pattern on the internal surface of a panel to approximately the same color. CONSTITUTION:Two or more differently emitting fluorescent blocks, red 11, green 12 and blue 13, are formed on the internal surface of a transparent panel to serve as fluorescent face for a color display tube to be used in an airplane or car. P-22, P-1 and P-22 are used for red, green and blue light-emitting substances, respectively, whose body colors shall be all unified to white. Accordingly, ugly appearance and inconvenience can be reduced and possible fatigue for an observer prevented.
