Description

投写型表示装置Projection display

　本発明は、光学エンジンを備えた投写型表示装置に関する。 The present invention relates to a projection display device provided with an optical engine.

　プロジェクタのような投写型表示装置は、光源や光学エンジンなどの構成部品を収容する筐体を備えている（特開２００９－２６５３７８号公報）。光学エンジンは、入力信号に応じた投写光を生成する精密な光学部品を備えている。 A projection display device such as a projector includes a housing that houses components such as a light source and an optical engine (Japanese Patent Laid-Open No. 2009-265378). The optical engine includes a precise optical component that generates projection light according to an input signal.

特開２００９－２６５３７８号公報JP 2009-265378 A

　温度変化により筐体に歪みが生じると、光学エンジンに歪みによる負荷がかかる。光学エンジンは精密な光学部品を備えているため、負荷によって投写光の品質が低下することがある。そこで、筐体の歪みに起因する光学エンジンの負荷を抑制することができる投写型表示装置が望まれる。 If the housing is distorted due to temperature changes, the optical engine will be subjected to strain. Since the optical engine is equipped with precise optical components, the quality of the projected light may be reduced by the load. Therefore, a projection display device that can suppress the load on the optical engine due to the distortion of the housing is desired.

　本発明の一実施形態における投写型表示装置は、筐体と、筐体内に設けられ、入力信号に応じた投写光を生成する光学エンジンと、を備えている。光学エンジンは振動吸収体を介して前記筐体に固定されている。 A projection display apparatus according to an embodiment of the present invention includes a housing and an optical engine that is provided in the housing and generates projection light according to an input signal. The optical engine is fixed to the housing via a vibration absorber.

　温度変化によって筐体に歪みが生じた場合であっても、振動吸収体によって、筐体の歪みの影響に伴う光学エンジンの負荷が緩和される。 Even if the case is distorted due to temperature changes, the vibration absorber reduces the load on the optical engine due to the distortion of the case.

　次に、本発明の実施形態について図面を参照して説明する。以下の実施形態では、投写型表示装置としてのプロジェクタを例に挙げて詳細に説明する。 Next, an embodiment of the present invention will be described with reference to the drawings. In the following embodiments, a projector as a projection display device will be described in detail as an example.

　図１は、本発明の一実施形態おけるプロジェクタの斜視図である。図２はプロジェクタの正面図である。図３はプロジェクタの上面図である。図４は、図３のＡ－Ａ線に沿ったプロジェクタの断面図である。 FIG. 1 is a perspective view of a projector according to an embodiment of the present invention. FIG. 2 is a front view of the projector. FIG. 3 is a top view of the projector. FIG. 4 is a cross-sectional view of the projector along the line AA in FIG.

　プロジェクタ１０は、構成部品を収容する筐体１２を備えている。筐体１２は、プラスチックから形成されていて良い。筐体１２内には、光源、光学エンジン１４および投写レンズ１６が設けられている。光源は光学エンジン１４に入射する光を発する。光学エンジン１４は、入射光から、入力信号に応じた投写光を生成する。投写レンズ１６は、光学エンジン１４で生成された投写光を筐体１２の外部へ投写し、スクリーンに画像を投映する。 The projector 10 includes a housing 12 that accommodates components. The housing 12 may be formed from plastic. A light source, an optical engine 14 and a projection lens 16 are provided in the housing 12. The light source emits light incident on the optical engine 14. The optical engine 14 generates projection light corresponding to the input signal from the incident light. The projection lens 16 projects the projection light generated by the optical engine 14 to the outside of the housing 12 and projects an image on the screen.

　光学エンジン１４は、入力信号に応じた投写光を生成する画像形成素子を有している。画像形成素子は、液晶パネルのような透過型の画像形成素子や、デジタルミラーデバイス（ＤＭＤ）のような反射型の画像形成素子等であって良い。また、光学エンジン１４は、集光レンズや反射ミラー等の光学素子を備えていて良い。 The optical engine 14 has an image forming element that generates projection light according to an input signal. The image forming element may be a transmissive image forming element such as a liquid crystal panel or a reflective image forming element such as a digital mirror device (DMD). The optical engine 14 may include an optical element such as a condenser lens or a reflection mirror.

　光学エンジン１４は、振動吸収体２０を介して筐体１２に固定されている。つまり、光学エンジン１４は、ネジなどにより筐体１２に直接固定されていない。これにより、温度変化によって筐体１２に歪みが生じた場合であっても、振動吸収体２０によって、筐体１２の歪みに伴う光学エンジン１４にかかる力が小さくなる。つまり、光学エンジンにかかる外力が緩和される。光学エンジン１４は、複数の精密な光学部品を備えている。光学エンジンに外力がかかると、各光学部品が配置されている部材が変形する。この変形により、各光学部品の配置や相対位置が変化してしまう。その結果として、投写された画像が歪んだり、焦点が合わなくなったりしてしまう。光学エンジン１４は振動吸収体２０を介して筐体１２に固定すると、筐体１２の歪に伴う力が光学エンジン１４に伝達しにくくなる。そして、各光学部品の配置や相対位置などの変化も緩和される。よって、投写された画像の変化も抑制される。つまり、所謂「投写光の品質」が維持される。 The optical engine 14 is fixed to the housing 12 via the vibration absorber 20. That is, the optical engine 14 is not directly fixed to the housing 12 with screws or the like. Thus, even when the housing 12 is distorted due to a temperature change, the force applied to the optical engine 14 due to the distortion of the housing 12 is reduced by the vibration absorber 20. That is, the external force applied to the optical engine is reduced. The optical engine 14 includes a plurality of precision optical components. When an external force is applied to the optical engine, the member on which each optical component is arranged is deformed. This deformation changes the arrangement and relative position of each optical component. As a result, the projected image is distorted or out of focus. When the optical engine 14 is fixed to the housing 12 via the vibration absorber 20, it becomes difficult to transmit the force accompanying the distortion of the housing 12 to the optical engine 14. Also, changes in the arrangement and relative position of each optical component are alleviated. Therefore, changes in the projected image are also suppressed. That is, the so-called “projected light quality” is maintained.

　図５および図６は、振動吸収体２０の構成の好ましい一例を示している。この振動吸収体２０は、第１の振動吸収材料２２と第２の振動吸収材料２４とを含んでいる。図６では、点線Ｂよりも上の部分が第１の振動吸収材料２２であり、点線Ｂよりも下の部分が第２の振動吸収材料２４となっている。第１の振動吸収材料２２は、第２の振動吸収材料２４よりも硬度（ショアＡ型）が高い。互いに硬度の異なる振動吸収材料２２，２４は、弾性伸縮の効果も異なる。この弾性伸縮の違いを利用することにより、振動吸収体２０は、筐体１２の歪みの影響をより効率的に緩和することができる。 5 and 6 show a preferable example of the configuration of the vibration absorber 20. The vibration absorber 20 includes a first vibration absorbing material 22 and a second vibration absorbing material 24. In FIG. 6, the portion above the dotted line B is the first vibration absorbing material 22, and the portion below the dotted line B is the second vibration absorbing material 24. The first vibration absorbing material 22 has higher hardness (Shore A type) than the second vibration absorbing material 24. The vibration absorbing materials 22 and 24 having different hardnesses also have different elastic expansion and contraction effects. By utilizing the difference between the elastic expansion and contraction, the vibration absorber 20 can more efficiently reduce the influence of the distortion of the housing 12.

　２種類の振動吸収材料２２．２４からなる振動吸収体２０は、二色成形によって一体的に形成されることが好ましい。これにより、振動吸収体２０の製造工数の削減や振動吸収体２０の形状の自由度を向上させることができる。その結果、振動吸収体２０が異なる材料を含んでいたとしても、振動吸収体２０の美観を保つことができる。各々の振動吸収材料２２，２４は、シリコーンゴムであっても良く、シリコーンゴム以外のエラストマーであっても良い。振動吸収材料２２，２４として、その他の振動吸収機能を有する材料を用いることもできる。 The vibration absorber 20 made of the two types of vibration absorbing materials 22.24 is preferably formed integrally by two-color molding. Thereby, the reduction of the manufacturing man-hour of the vibration absorber 20 and the freedom degree of the shape of the vibration absorber 20 can be improved. As a result, even if the vibration absorber 20 includes different materials, the aesthetic appearance of the vibration absorber 20 can be maintained. Each of the vibration absorbing materials 22 and 24 may be a silicone rubber or an elastomer other than the silicone rubber. As the vibration absorbing materials 22 and 24, other materials having a vibration absorbing function can be used.

　また、振動吸収体２０は、筐体１２から光学エンジン１４または光学エンジン１４から筐体１２への振動の伝達を抑制または防止することもできる。図５および図６に示すように、振動吸収体２０が硬度の異なる複数の振動吸収材料２２，２４を含む場合、異なる周波数帯の振動成分が効率的に緩和される。その結果、筐体１２から光学エンジン１４に伝達される振動の抑制の効果が向上する。光学エンジンの振動の抑制により、投写画像の振動（画揺れ）の軽減を図ることができる。 The vibration absorber 20 can also suppress or prevent the transmission of vibration from the housing 12 to the optical engine 14 or from the optical engine 14 to the housing 12. As shown in FIGS. 5 and 6, when the vibration absorber 20 includes a plurality of vibration absorbing materials 22 and 24 having different hardnesses, vibration components in different frequency bands are efficiently relaxed. As a result, the effect of suppressing vibration transmitted from the housing 12 to the optical engine 14 is improved. By suppressing the vibration of the optical engine, the vibration (image shake) of the projected image can be reduced.

　比較的高度の高い第１の振動吸収材料２２が光学エンジン１４側に配置され、比較的高度の低い第２の振動吸収材料２４が筐体１２側に配置されても良い。この場合、光学エンジン１４から筐体１２へ伝達する振動が徐々に緩和され、筐体１２に達する振動の緩和効果がより向上するという利点がある。 The first vibration absorbing material 22 having a relatively high altitude may be disposed on the optical engine 14 side, and the second vibration absorbing material 24 having a relatively low altitude may be disposed on the housing 12 side. In this case, there is an advantage that the vibration transmitted from the optical engine 14 to the housing 12 is gradually reduced, and the effect of reducing the vibration reaching the housing 12 is further improved.

　また、振動吸収体２０は、貫通孔２６を有し、グロメット構造となっていても良い。この場合、筐体１２から突出したボス２０を振動吸収体２０の貫通孔２６に嵌めることができる。そして、振動吸収体２０を、光学エンジン１４の光学部品を保持する基板に形成された穴部に嵌め込むことにより、光学エンジン１４のフローティング構造が実現される。 The vibration absorber 20 may have a through hole 26 and have a grommet structure. In this case, the boss 20 protruding from the housing 12 can be fitted into the through hole 26 of the vibration absorber 20. And the floating structure of the optical engine 14 is implement | achieved by fitting the vibration absorber 20 in the hole formed in the board | substrate holding the optical component of the optical engine 14. FIG.

　図７および図８は、振動吸収体２１の構成の別の一例を示している。この振動吸収体２１は、第１の振動吸収材料２２と第２の振動吸収材料２４とを含んでいる。図８では、点線Ｃよりも左側の部分が第１の振動吸収材料２２であり、点線Ｃよりも右側の部分が第２の振動吸収材料２４となっている。第１の振動吸収材料２２は、第２の振動吸収材料２４よりも硬度（ショアＡ型）が高い。このように、互いに硬度の異なる振動吸収材料２２，２４を利用することにより、上述したように筐体１２の歪みの影響をより効率的に緩和することができる。 7 and 8 show another example of the configuration of the vibration absorber 21. FIG. The vibration absorber 21 includes a first vibration absorbing material 22 and a second vibration absorbing material 24. In FIG. 8, the portion on the left side of the dotted line C is the first vibration absorbing material 22, and the portion on the right side of the dotted line C is the second vibration absorbing material 24. The first vibration absorbing material 22 has higher hardness (Shore A type) than the second vibration absorbing material 24. Thus, by using the vibration absorbing materials 22 and 24 having different hardnesses, the influence of the distortion of the housing 12 can be more efficiently reduced as described above.

　また、第１の振動吸収材料２２と第２の振動吸収材料２４とは、振動吸収体２０に荷重がかかる方向から見て横方向に並んで配置されていて良い。この場合、横方向における筐体１２の歪みの影響を緩和する効果や、横方向における振動を抑制する効果が向上する。 Further, the first vibration absorbing material 22 and the second vibration absorbing material 24 may be arranged side by side in the lateral direction when viewed from the direction in which the load is applied to the vibration absorber 20. In this case, the effect of reducing the influence of the distortion of the housing 12 in the lateral direction and the effect of suppressing vibration in the lateral direction are improved.

　図５～８に示す振動吸収体２０，２１は、筐体１２に設けられた脚部３０にも取り付けることができる。この場合、筐体１２を置くステージから筐体１２へ伝達する振動を抑制することができる。筐体１２の振動が抑制されることで、投写画像の画揺れを防止することができる。また、筐体１２の振動が抑制されると、筐体１２内に設置された部品の破損やねじ緩みを防止することもできる。さらに、筐体１２の振動が抑制された結果、光学エンジン１４の振動も抑制されるため、光学エンジン１４の寿命や信頼性の向上を図ることができる。 The vibration absorbers 20 and 21 shown in FIGS. 5 to 8 can also be attached to the legs 30 provided in the housing 12. In this case, vibration transmitted from the stage on which the housing 12 is placed to the housing 12 can be suppressed. By suppressing the vibration of the housing 12, it is possible to prevent the projected image from shaking. Further, when the vibration of the housing 12 is suppressed, it is possible to prevent breakage of parts installed in the housing 12 and screw loosening. Further, as a result of the vibration of the housing 12 being suppressed, the vibration of the optical engine 14 is also suppressed, so that the life and reliability of the optical engine 14 can be improved.
