産業上の利用分野
本発明は投写型テレビジョン受像機に用いることができ
るスクリーンに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a screen that can be used in a projection television receiver.
従来例の構成とその問題点
テレビの映像をレンズを通してスクリーンに投写拡大し
て、その映像を投写する反対側から見る投写型テレビジ
ョン受像機は一般に知られている。Conventional Structure and Problems Projection type television receivers are generally known in which a television image is projected and enlarged onto a screen through a lens, and the image is viewed from the opposite side.
この受像機のスクリーン(リヤタイプスクリーン成るい

のスクリーンは構造は簡単であるが、投写された映像が
非常に暗いという欠点がある。The screen (rear type screen or transmission type screen) of this receiver is conventionally made of resin such as vinyl chloride resin or polymethyl methacrylic resin, glass, quartz, etc. for those with a size of 70 inches or more. Notebooks containing fine powders such as so-called light diffusing agents have been used. Although this screen has a simple structure, it has the disadvantage that the projected image is very dark.
発明の目的
本発明は上記欠点を除去し、明るい画像を得ることがで
き、しかも大型のものを得ることができるスクリーンを
提供しようとするものである。OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks and to provide a screen that can provide bright images and can also be made large.

ストライプ層を設けたものである。Structure of the Invention The present invention comprises lenticular lenses in which a plurality of lenticular lenses each having a black stripe layer formed in parallel with the semi-cylindrical shape on a surface other than the original light-condensing surface on the opposite side of the semi-cylindrical surface are arranged in a horizontal direction, and a light diffusing agent is mixed therein. The lenticular lenses are attached to a sheet, and a black stripe layer is provided on the sheet facing the joint between the lenticular lenses.
実施例の説明
以下本発明の一実施例について図面を参照して説明する
。図に示すように、レンチキュラーレンズ1a、1bは
表面蒲鉾状であるため押出し成型によって作ることがで
きるため巾りは小さいが長さは十分長いものが得られる
。その蒲鉾状部分と反対側の面の光の集光面以外は蒲鉾
形状と平行に黒色のストライプ層2a 、2bを印刷す
る。このブラックストライプ層付きレンチキュラーレン
ズ1a、1bは表面反射が少く、指向特性が良い。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in the figure, the lenticular lenses 1a and 1b have semicylindrical surfaces and can be made by extrusion molding, resulting in lenses having a small width but a sufficiently long length. Black stripe layers 2a and 2b are printed parallel to the semi-cylindrical shape on the surface other than the light condensing surface on the opposite side of the semi-cylindrical portion. The black stripe layered lenticular lenses 1a and 1b have little surface reflection and good directional characteristics.
このレンチキュラーレンズ1a、1bを二個並べて、光
拡散剤3を配合したシート4に接着剤5により接着する
。このとき単に接着するだけではレンチキュラーレンズ
1a、1bの合せ目6が目立って、映像にも影響するの
で、接着に先立って、貼合せるための大きなシート4に
あらかじめブラックストライプ層7を印刷しておき、こ
のストライプ層7に、レンチキュラーレンズ1a、1b
の合せ目6に来るように配置して、接着する。接着剤は
6は透明のものを用いる。Two lenticular lenses 1a and 1b are arranged side by side and bonded to a sheet 4 containing a light diffusing agent 3 using an adhesive 5. At this time, if the lenticular lenses 1a and 1b are simply bonded together, the seam 6 of the lenticular lenses 1a and 1b will be noticeable and affect the image, so before bonding, a black stripe layer 7 is printed in advance on a large sheet 4 for bonding. , this stripe layer 7 has lenticular lenses 1a, 1b.
Place it so that it is at seam 6 and glue it. For adhesive 6, use a transparent adhesive.
発明の効果
以上のように本発明はレンチキュラーレンズの合せ目部
分の透過性はシートによって、表面の反射光はブラック
ストライプ層によって各々吸収され、合せ目は全く目立
たなくなる。従って、ブラックストライプ層付のレンチ
キュラーレンズシートと複数個、並べることによって、
明るい良好な画像を得ることができる大型のスクリーン
を提供することができるものである。Effects of the Invention As described above, in the present invention, the transparency of the seam portion of the lenticular lens is absorbed by the sheet, and the reflected light on the surface is absorbed by the black stripe layer, so that the seam becomes completely inconspicuous. Therefore, by arranging multiple lenticular lens sheets with black stripe layers,
It is possible to provide a large screen that can provide bright and good images.
