Title: Illumination light reflection preventing mechanism in display of emission system
Inventor: TAGUCHI FUJITAKA
IPC: H04N5/72
Filed: 1990-05-01
Abstract: PURPOSE:To sufficiently obtain an illumination light reflection preventing effect without modifying a light source for illumination itself by utilizing two polarizing filters reasonably. CONSTITUTION:A first polarizing filter 3 is arranged at a light source 1 for illumination side, and also, a second polarizing filter 5 is arranged at the front side of the display plane 4 of a display 2 of emission system so as to make a polarizing direction intersect orthogonally to that of the first polarizing filter 3. Light 8a emitted from the light source 1 for illumination i.e. natural light becomes linearly polarized light 8b passing the first polarizing filter 3, however, it can be used as illumination light in a room. In such a way, the linearly polarized light 8b is made incident on the second polarizing filter 5. The linearly polarized light 8b is absorbed in the second polarizing filter 5, not arriving at the display plane 4 of the display 2. Thereby, display information on the display plane 4 can be obtained from the front plane 6 side of the second polarizing filter 5 without reflection on the light source 1 for illumination from the display plane 4.
