VC and VR.<\/p>\n<p>The phosphors for VC and VR are 180\u00c2\u00b0 out of phase because they are excited by different electron beams. The electron beam for VC is excited by the vertical deflection signal, while the electron beam for VR is excited by the horizontal deflection signal. The vertical deflection signal is 180\u00c2\u00b0 out of phase with the horizontal deflection signal, so the phosphors for VC and VR are also 180\u00c2\u00b0 out of phase.<\/p>\n<p>The phosphors for VL and VR are not 180\u00c2\u00b0 out of phase because they are excited by the same electron beam.
