Abstract
The combiner 1 has a resin base 11 and a reflecting and polarizing member 12. The reflecting and polarizing member 12 is unitarily molded with the resin base 11 as an insert and has a polarizer plate 12A covered by a reflector film 12B. At a border B of the reflector member 12 with the resin base 11, a gradation printed layer 13a is provided. Preferably, the reflector film has an undercoat layer 12d, a reflecting coat layer 12e, an overcoat layer 12f, and a top coat layer 12g. The undercoat layer prevents the reflector film from being stripped out of the polarizer plate, and the reflector film has a predetermined reflectance. The reflecting coat layer is protected by the overcoat layer, and the top coat layer has a water repellency.
Claims14
A combiner comprising a resin base and a reflecting and polarizing member, wherein the reflecting and polarizing member is unitarily molded as an insert with the resin base and has a polarizer plate covered by a reflector film.
A combiner manufacturing method comprising the steps of:
- sequentially layering an undercoat layer, a reflecting coat layer, an overcoat layer, and a top coat layer on a polarizer plate through coating processes to define a polarizing and reflecting member,
- arranging the polarizing and reflecting member as an insert at a predetermined position in a cavity of a molding die for forming the combiner, and
- injecting a molten thermoplastic resin base material in the molding die before cooling the base material for solidification.
An on-vehicle display unit comprising;
- a display device,
- a prism assembly having a first prism and a second prism which are disposed in front of a screen of the display device, the first and second prisms being layered such that the first prism has a vertex oriented opposite to that of the second prism,
- a combiner for reflecting and guiding display rays toward a diver's eye, the display rays delivered through the prism assembly from the display device, and
- a second polarizer plate disposed between the prism assembly and the combiner,
- wherein the combiner comprises a resin base and a reflecting and polarizing member, and the reflecting and polarizing member is unitarily molded as an insert with the resin base and has a polarizer plate covered by a reflector film, the polarizer plate of the combiner being perpendicular to the second polarizer plate in polarizing axes.
A combiner comprising a resin base and a reflecting and polarizing member wherein the reflecting and polarizing member has a polarizer plate covered by a reflector film, the reflecting and polarizing member unitarily molded as an insert with the resin base, and a gradation print layer is provided between the resin base and the reflecting and polarizing member.
A combiner manufacturing method comprising the steps of:
- masking a polarizer plate with a mask having a first masking section and a second masking section, the first masking section having an opening slightly smaller than the polarizer plate, the second masking section having a masking pattern-which is constituted by a plurality of circles or stripes that are spaced from each other such that a masking ratio of the masking pattern becomes gradually smaller inwardly from an inner periphery of the opening of the first masking section,
- sequentially layering an undercoat layer, a reflecting coat layer, an overcoat layer, and a top coat layer on the polarizer plate through coating processes to define a polarizing and reflecting member,
- arranging the polarizing and reflecting member as an insert at a predetermined position in a cavity of a molding die for forming the combiner,
- injecting a molten thermoplastic resin base material in the molding die before cooling the base material for solidification, and, and
- removing the mask and providing a gradation print layer on a portion of the polarizer plate which has been covered by the mask in the masking step.
An on-vehicle display unit comprising:
- a display device,
- a prism assembly having a first prism and a second prism which are disposed in front of a screen of the display device, the first and second prisms being layered such that the first prism has a vertex oriented opposite to that of the second prism,
- a combiner for reflecting and guiding display rays toward a diver's eye, the display rays delivered through the prism assembly from the display device, wherein the combiner has a resin base and a reflecting and polarizing member, the reflecting and polarizing member unitarily molded as an insert with the resin base and having a polarizer plate covered by a reflector film, and a gradation print layer is provided between the resin base and the reflecting and polarizing member, and
- a second polarizer plate disposed between the prism assembly and the combiner, the second polarizer plate being perpendicular to the polarizer plate of the combiner in polarizing axes.
