摘要 |
An optical system in a projection television receiver includes: a screen for simultaneously displaying R (Red), G (Green) and B (Blue) images thereon; and a light source part comprising R, G and B cathode ray tubes. The R and B cathode ray tubes project the R and B images on the screen via a reflecting mirror, whereas the G cathode ray tube is set together with the R and B cathode ray tubes in a delta type array and projects the G image directly on the screen.
