Definitions
- the invention relates to a polarizing mirror for viewing purposes having a first plane reflecting light of a first kind of polarization to a viewing side, the mirror passing light of a second kind of polarization and being provided with a display device at its non-viewing side, which display device during use provides light of the second kind of polarization, the polarizing mirror being switchable between a state passing light of the second kind of polarization and reflecting light of the first kind of polarization and a state passing light of both kinds of polarization.
- a "mirror for viewing purposes” or “display mirror” in this application refers to a mirror, via which a person's eye (or an artificial eye like a (infra-red) camera lens) sees a reflected part of the outside world.
- a mirror plane acts as a polarizing plane.
- light within a certain range of a wavelength of light incident on a polarizing plane will be divided in two components one which is reflected by the polarizing plane and one of which passes through the polarizing plane.
- light within a certain range of a wavelength of light incident on a polarizing plane will be divided in two components one which is reflected by the polarizing plane and one of which passes through the polarizing plane.
- light within a certain range of a wavelength of light incident on a polarizing plane will be divided in two components one which is reflected by the polarizing plane and one of which passes through the polarizing plane.
- the division of light in two components having linearly polarized, perpendicular directions of polarization are generally known.
- light is generally supposed to be divided in right-handed and left-handed circular polarization but the invention is equally applicable to light being divided in linearly polarized, perpendicular directions of polarization.
- the displays in examples based on circular polarization are supposed to provide light of the second kind of circular polarization, which does not exclude displays, which do emit or provide (e.g. an LCD having a backlight) linearly or non-polarized light.
- Linearly polarized light as generally provided by LCDs may be converted into circularly polarized light by means of a quarter lambda plate, while non-polarized as generally provided by e.g.
- (O)LED -displays or plasma displays may be converted into circularly polarized light by means of a 14 lambda plate (retarder).
- the mirror function is obtained by introducing a polarizing mirror or reflective polarizer instead of a partly reflecting layer in front of a display device.
- a polarizing mirror according to the invention has at its non- viewing side between the display device and the polarizing mirror a switchable polarizer
- the switchable polarizer may be switchable between a state passing light of the first kind of polarization and reflecting light of the second kind of polarization and a state passing light of both kinds of polarization.
- the polarizing mirror and switchable polarizers are cholesteric polarizers.
- Figure 1 is a possible embodiment of a mirror device according to the invention
- Figure 2 is a diagrammatic cross-section of a part of such a mirror device
- Figures 3a, 3b are diagrammatic cross-sections of a part of a mirror device according to the invention
- Figures 4a, 4b are diagrammatic cross-sections of a part of another mirror device according to the invention
- Figure 5 shows the bandwidth of the cholesteric mirror as function of time during manufacture
- Figure 6 shows the temperature dependency of the bandwidth of such a cholesteric mirror.
- the Figures are diagrammatic and not drawn to scale. Corresponding elements are generally denoted by the same reference numerals.
- Figure 1 shows a mirror device 1 for viewing purposes having on a glass plate or any other substrate 4 a mirror 2, in this example a cholesteric mirror, reflecting light, so a person 3 sees his image 3' (and further background, not shown).
- the mirror (plane) in one state only reflects light of a first kind of polarization (twist, e.g. right-handed), but passes light of a second kind of polarization (the opposite twist, left- handed).
- the mirror is provided with a display device 5 at its non- viewing side (see also Figure 2).
- the display device 5 in this example is a liquid crystal display device having between two substrates (glass or plastic or any other suitable material) a liquid crystal material 7.
- the display 5 Since most liquid crystal display devices are based on polarization effects the display 5 during use substantially emits polarized light. In general light from a backlight 10 is modulated by the liquid crystal display effect. Since the liquid crystal display device is based on a polarization effect the display device 5 comprises a first polarizer 8 and a second polarizer (or analyzer) 9, which passes light of a certain polarization (twist). If this light of a certain polarization twist has the same polarization twist as the second kind of polarization, it passes the mirror (plane) 2 without any loss of light (100 % transmission). Since most liquid crystal display devices are based on modulation of linearly polarized light, usually linear polarizers 8, 9 are used.
- Figure 3a, 3b show a part of a mirror display device according to the invention in which the mirror 2 is switchable between a state passing light of the second kind of polarization and reflecting light of the first kind of polarization ( Figure 3b) and a state passing light of both kinds of polarization ( Figure 3a).
- the mirror 2 is a switchable cholesteric polarizer.
- a second switchable (cholesteric) polarizer 11 is provided between the display device 5 and the polarizing mirror 2, which switchable polarizer 11 is switchable between a state passing light of the first kind of polarization and reflecting light of the second kind of polarization and a state passing light of both kinds of polarization.
- a liquid crystal display device 15 is used, comprising a further quarter lambda plate 6. Since most liquid crystal display devices are based on modulation of linearly polarized light, light from the display is given a circular polarization by means of a (not shown) quarter lambda plate.
- FIG. 3a showing the display- mode
- the display device 5 emits light of the second kind of polarization (circularly (left- handed) polarized light, arrow 20). Since both the switchable (cholesteric) polarizer 11 and the polarizing mirror 2 are in a state passing light of both kinds of polarization (off-state), this circularly (left-handed) polarized light passes both the polarizer 11 and the polarizing mirror 2 (arrows 20', 20"), leading to a transmission of (theoretically) 100%.
- incident light 30 passes both the polarizing mirror 2 and the polarizer 11 (arrows 30', 30"), after which it is absorbed in the display device 5, although some (non -) polarized light 31 (or any other spurious light) may be reflected in this display-mode.
- the display device 5 emits light of the second kind of polarization (circularly (left-handed) polarized light, arrow 20), while the switchable (cholesteric) polarizer 11 reflects of the second kind of polarization (arrow 20'), which is absorbed again in the display device 5.
- the polarizing mirror 2 now partly (50%) reflects (one polarization twist (right-handed), in this example indicated by arrow 35) of the incident light (arrow 30) and passes circularly (left-handed) polarized light (arrow 30', the remaining 50%).
- the switchable (cholesteric) polarizer 1 1 reflects said (left-handed) polarized light again, while the polarizing mirror 2 passes said light (arrows 35', 35"), leading to a reflection of (theoretically) 100%.
- both the polarizing mirror 2 and polarizer 11 are switched off. In this case there is no mirror and the display can be observed without a reflection superimposed on it.
- switchable cholesteric mirror 2 is shown in combination with a switchable cholesteric polarizer of the opposite sense (reflecting respectively left-handed and right-handed polarized light).
- Figures 4a, 4b in a similar way show a device having a similar switchable cholesteric mirror 2 but this time in combination with switchable cholesteric polarizer of the same sense (both are reflecting left-handed (or right-handed ) polarized light). The same effect as described with respect to Figure 3 can now be obtained by introducing a V.
- the V. lambda retarder 12 may be a broadband retarder but preferably is centered around wave-lengths of 570nm. As a result, substantially all incident light in principle is reflected in the display mode. Also the effects of spurious light are diminished. Light passing the cholesteric polarizers described above may become elliptically polarized at lager angles of incidence. In order to compensate for the elliptically it extra retarders can be used with a negative birefringence within the system.
- Such a retarder can be placed for example underneath the l A lambda retarder of Figures 4a, 4b when cholesteric polarizers of the same sense is used.
- cholesteric polarizers haveg the same sense, only a retarder with a negative birefringence is used without the need for Vi lambda retarder.
- a switchable cholesteric polarizer (mirror) 2, 11 can be produced by polymerizing mono and diacrylates in the presence of non-reactive LC molecules in the chiral nematic phase. During polymerization some of the mixtures show the tendency of to phase separation This tendency could be influenced by various parameters.
- the protective scope of the invention is not limited to the embodiments described.
- the second polarizer (or analyzer) 9 in Figure 2 may be deleted, if wanted.
- a backlit transmissive liquid crystal display device has been described, the use of reflective liquid crystal display devices is not excluded.
- light from e.g. an (O)LED a plasma displays or electrophoretic display may be polarized or it may even be attractive to use other display effects to obtain the effect of a high contrast of displayed information with respect to reflected images in mirror applications.
- more than one display 5 can be integrated in the mirror, whereas many other applications areas can be thought of (rear view mirrors, fitting rooms, etcetera).
