Description

本考案は、３Ｄ立体表示システムに関し、特に、異なる極性を有する光源を出力するとともに、光源の利用率を有効に高める３Ｄ立体表示システムに関する。 The present invention relates to a 3D stereoscopic display system, and more particularly to a 3D stereoscopic display system that outputs light sources having different polarities and effectively increases the utilization rate of the light sources.

情報時代の到来と光学技術及び投影表示装置の発展により、高解像度及び大画面のデジタルプロジェクタは、職場でのプレゼンテーション、会議、教育訓練、さらには家庭内での娯楽において画像を見るために必要不可欠である。そのため、高品質画像、高輝度、小体積は、消費者がプロジェクタを購入する際の重大な判断基準となっている。 With the advent of the information age and the development of optical technology and projection display devices, high-resolution and large-screen digital projectors are indispensable for viewing images in workplace presentations, meetings, education and training, as well as in-home entertainment. It is. For this reason, high quality images, high brightness, and a small volume are important criteria for consumers to purchase projectors.

映像娯楽に対するニーズの増大及び投影技術の継続的な改良に伴い、プロジェクタの性能は、従来の平面画像から３Ｄ立体画像に変化してきている。従来技術では、２台の表示（投影）システムによりＳ極偏光ビーム及びＰ極偏光ビームをそれぞれ発生させるのが一般的であるが、２台の表示システムを同時に使用した場合、余計なコストがかかる上、占有空間も大きい。本考案者は、上述の問題点を解決するために、２台の表示システムを同時に使用せずに３Ｄ投影効果を発生させることができる発明を案出した（特許文献１）。この３Ｄプロジェクタの設計及び製造は、薄型軽量でコストを減らすことができる。 With increasing needs for video entertainment and continuous improvements in projection technology, the performance of projectors is changing from conventional planar images to 3D stereoscopic images. In the prior art, it is common to generate an S-polarized beam and a P-polarized beam by two display (projection) systems. However, when two display systems are used at the same time, extra cost is required. In addition, the occupied space is large. In order to solve the above-mentioned problems, the present inventor has devised an invention that can generate a 3D projection effect without using two display systems simultaneously (Patent Document 1). The design and manufacture of this 3D projector is thin and lightweight and can reduce costs.

しかし、従来の３Ｄ投影技術又は表示技術では、高価な能動タイプの眼鏡又は赤青の受動タイプの３Ｄ眼鏡を使用する必要がある上、光源利用率が低いため、本考案者は特許文献１の発明を改良し、本案の表示システムを案出した。この技術は何れの３Ｄ立体表示システム（例えば、３Ｄ表示装置又は３Ｄプロジェクタ）にも応用することができる。本考案は、光源の利用率を高めることができるだけでなく、「受動タイプの偏光メガネ」を使用するだけで、ユーザはフルカラーの３Ｄ画面を見ることができる。 However, in the conventional 3D projection technology or display technology, it is necessary to use expensive active type glasses or red-blue passive type 3D glasses, and the light source utilization rate is low. The invention was improved and a display system of the present plan was devised. This technique can be applied to any 3D stereoscopic display system (for example, a 3D display device or a 3D projector). The present invention not only can increase the utilization rate of the light source, but also allows the user to view a full-color 3D screen only by using “passive type polarized glasses”.

第１の光束及び第２の光束は、最終的に画像投影モジュール（投影レンズ）３０からプロジェクションスクリーン４へ投影される。プロジェクションスクリーン４上の画像は、Ｐ極偏光ビーム及びＳ極偏光ビームを同時に有するため、ユーザは、「受動タイプの偏光レンズ」を用いることにより、フルカラーの３Ｄ画像を見ることができる。 The first light flux and the second light flux are finally projected from the image projection module (projection lens) 30 onto the projection screen 4. Since the image on the projection screen 4 has a P-polarized beam and an S-polarized beam at the same time, the user can view a full-color 3D image by using a “passive type polarization lens”.
