Projection color TV using CRTs having interference filters with different number of layers |
摘要 |
The variation in center-to-edge luminance gradient along the minor axis of the red-emitting and/or blue-emitting tube having a multilayer interference filter, is reduced by reducing the number of layers in the filter making it easier to match the gradients to that of the green-emitting tube, and thereby improve the white field uniformity of a projection color TV employing three monochrome cathode ray tubes.
