摘要 |
<p>Radiation from a radiation source (2) is converted into light of a desired spectral character by causing the radiation from tne source (2) to excite luminescent material (18) which is present between two interference filters (22, 23). In combination with opto-electronic elements monochrome pictures are obtained which are suitable for use in projection television. The sandwich of luminescent material (18) and interference filters (22, 23) may form part of a display device (3), for example an LCD, but it may alternatively be integrated, together with the radiation source, to form a separate illumination source.</p> |
