Display device having a diffusing display panel and a reflecting polarizer |
摘要 |
Display device (1) comprising an illumination system (3) having a radiation source (17; 31, 35) for supplying a radiation beam. The display device (1) also comprises a diffusing display panel (5). This panel (5) consists of an optically active diffusing medium (7) which is switchable between a transparent, polarization-maintaining state and a diffusing, depolarizing state for the radiation beam. The medium (7) is present between a first polarizer (9) having a first state of polarization and a second polarizer (11) having a second, complementary state of polarization. At least the first polarizer (9) is a reflecting polarizer and polarization-converting means (10) are arranged at a side of the first polarizer (9) facing away from the display panel (5).
