Primary colour signals
- Spectral response of the optical section in the colour picture signal source, together with any matrix of the three sensor outputs, shall be such that the E’R, E’G, E’B signals will reproduce an image with optimum colour fidelity on a colour picture tube having phosphors with the following CIE*15 chromaticity coordinates, and balance for a white chromaticity of CIE Illuminant D65, shown in table A3.1.
Table A3.1: CIE*15 Chromaticity coordinates and balance for a white chromaticity of CIE illuminant D65
| Chromaticity | Coordinates | |
|---|---|---|
| X | Y | |
| Red phosphor | 0.64 | 0.33 |
| Green phosphor | 0.29 | 0.60 |
| Blue phosphor | 0.15 | 0.06 |
| Illuminant D65 | 0.313 | 0.329 |
