Document Type and Number:
Japanese Patent JP4601360
Kind Code:
B2
Abstract:
A light controlling element 15 comprises vertical linear polarisers 16 positioned between transparent substrates 17, and serves to output light having a first polarisation state in a first angular range and light having a second, different polarisation state in a second, greater angular range. The linear polarisers 16 may be horizontal (Figure 5), and the system may be incorporated in a display having a display panel such as an LCD, switchable half wave plate and backlight (Figure 6). The light controller may be used in a three dimensional, autostereoscopic or dual view display. Also disclosed are manufacturing methods adhering stacked polarising sheets together, removing selected polariser regions and providing polarising material or light transmitting substrates in recesses in the element.
