この発明はＣＲＴディスプレイ装置のスクリーン表面形
状に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to the screen surface shape of a CRT display device.
（従来の装置）
従来のＣＲＴディスプレイ装置は、第３図及び第４図に
示すように、スクリーン１の外面形状がブラウン管２の
蛍光面形状に沿う凸曲面となっている。３はフレームを
示している。なお、スクリーン１面内の複数の線は凸曲
面の理解を容易にするためである。(Conventional Device) In a conventional CRT display device, as shown in FIGS. 3 and 4, the outer surface of the screen 1 is a convex curved surface that follows the shape of the phosphor screen of the cathode ray tube 2. 3 indicates a frame. Note that the plurality of lines within one surface of the screen is to facilitate understanding of the convex curved surface.
このため、スクリーン１正面から到来した外部光がスク
リーン外形に対して外方に向かって散乱反射されるので
、画面が見にくくなり、目にかかる負担が大きくなると
いう問題があった。For this reason, external light arriving from the front of the screen 1 is scattered and reflected outward with respect to the outer shape of the screen, making it difficult to see the screen and increasing the burden on the eyes.
この発明は上記問題を解決するためになされたもので、
従来に比し、画面が見易く、目に負担のかからないＣＲ
Ｔディスプレイ装置を得ることを目的する。This invention was made to solve the above problem.
CR that makes the screen easier to read and puts less strain on the eyes than before
The purpose is to obtain a T display device.
この発明は上記目的を達成するため、スクリーン表面形
状を凹曲面としたものである。In order to achieve the above object, the present invention provides a screen with a concave surface shape.
この発明では、外部光の反射光を一定の方向へ集め、外
部光が画面を見る者の目に反射しないようにすることが
できる。In this invention, the reflected light of external light can be collected in a certain direction, and the external light can be prevented from being reflected in the eyes of the person viewing the screen.
第１図はこの発明の一実施例を示す正面図であって、ス
クリーン１０の表面形状が、第２図の断↓
面図に示されるように、凹曲面となついる点において前
記第３図の従来のものと相違する。FIG. 1 is a front view showing an embodiment of the present invention, and the surface shape of the screen 10 shown in FIG. It is different from the conventional one.
この構成では、スフリーフ１Ｏ面に入射した外部光の反
射はスクリーン１０の外形より内側に向うので、スクリ
ーン１０表面の曲面形状を適切にすることにより、反射
光をスクリーン１０表面を見る者、例えばオペレータの
目視範囲外に向けることができ、外部光の反射による画
面の見にくさを緩和することができる。In this configuration, the reflection of external light incident on the surface of the fleece 10 is directed inward from the outer shape of the screen 10. Therefore, by optimizing the curved shape of the surface of the screen 10, the reflected light can be directed to the person viewing the surface of the screen 10, such as an operator. The screen can be directed outside the viewing range, reducing the difficulty of viewing the screen due to reflection of external light.
この発明は以上説明した通り、スクリーンによる外部光
の散乱反射を防ぐことができるので、画面が見易くなり
、目の疲労を軽減することができる利点がある。As explained above, this invention has the advantage that it can prevent the screen from scattering and reflecting external light, making the screen easier to see and reducing eye fatigue.
第１図及び第２図はこの発明の実施例の正面図及び側断
面図、第３図及び第４図は従来のＣＲＴディスプレイ装
置の正面図及び側断面図である。
図において、２−ブラウン管、１０−スクリーン。
なお、図中、同一符号は同一または相当部分を示す。1 and 2 are a front view and a side sectional view of an embodiment of the present invention, and FIGS. 3 and 4 are a front view and a side sectional view of a conventional CRT display device. In the figure, 2 - cathode ray tube, 10 - screen. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.
