Abstract

PURPOSE:To obtain a large-size, screen which forms a bright picture, by providing a sheet with a black stripe layer opposite to the interface of lenticular lenses. CONSTITUTION:The lenticular lenses 1a and 1b have semicylindrical surfaces; they are formed by extrusion to long length, but their width L is small. The black stripe layers 2a and 2b are printed in parallel to the semicylindrical shapes except on light condensing surfaces opposite to the semicylindrical parts. Those two lenticular lenses 1a and 1b are arranged and adhered to the sheet 4 which contains a mixed light diffusing agent 3 with an adhesive 5. The black stripe layer 7 is printed on the sheet 4 prior to the adhesion and the interface of the lenticular lenses 1a and 1b is aligned to the stripe layer 7. Further, the adhesive 5 is transparent.

Description

【発明の詳細な説明】 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.

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.

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.

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.

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.

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.
