Abstract
PURPOSE: To make it possible to perform simply and surely phase adjustment for color fluorescent material stripes of color switching signals by a PLL circuit.
CONSTITUTION: An electron beam scans the horizontal scanning start part by horizontal blanking signal HB to detect the light from an index fluorescent material stripe. This index signal SI has frequency fI which is determined by the pitch of index fluorescent material stripes and the scanning speed of the electron beam. When index signal SI is supplied to a PLL circuit, for example signal SO which is quadruple magnitude of index signal SI, namely, which has a frequency three times as high as the triplet frequency and has the fall placed in the just middle between respective color fruorescent material stripes can be obtained as the output of the PLL circuit, so that position and phase adjustment for respective color fluorescent materials of color switching signals can be performed easily and surely.
