Description
【0001】
【産業上の利用分野】
この発明は、導光板を使った表示装置に関するものである。
【0002】
【従来の技術】
従来、導光板表示装置においては、導光板の表面にインクあるいは蛍光ペン等で書いて、図形や文字を表示させるのに、導光板と盲板を接触させない間隔を保ち、取り付けていた。しかしながら、この方法では導光板と盲板の間隔を狭くすれば、導光板あるいは盲板に曲がりや反り等が発生した場合、接触する可能性があり、導光板の表面に表示する文字などを書き込む圧力が導光板を曲げ、盲板との接触が起きやすくなった。以上のことから、導光板と盲板の間隔を狭くして、薄い表示板を製作することが困難であった。
【0003】
【発明が解決しようとする課題】
本発明は、導光板と盲板が接触すると、接触した部分で導光板を導光した光が強く光るために、接触することを防ごうとするものである。また、導光板と盲板を密着させると、導光板表面に書いた文字などは、明瞭に表示できなくなるという欠点を解決しようとするものである。盲板を導光板に替えて、2枚の導光板で表示していても、2枚の導光板が接触すると、導光板を導光している光が、接触した個所で外部に放射する欠点があった。
【0004】
【課題を解決するための手段】
上記目的を解決するための手段を説明すれば、導光板と盲板の間を隔てた隙間を作るために、表示したい文字や図形あるいは絵等を、印刷または、書き込みした樹脂等の塗膜の厚みで隔てている。樹脂等については、塗料の他、接着剤またはインキ等を使用してもよい。
【0005】
盲板に、図形等を書いたり印刷等をする樹脂等は、乾いても弾力を保つ材質を使用して、導光板の表面に密着させると、導光板に導光される光によって、表示する文字や図形等が明瞭に表示できる。盲板を導光板に替えて、2枚の導光板の間で常に文字や図形あるいは絵等を表示させることもできる。この場合、盲板に替えた導光板にも、光源から導光させた光で、表面に書いた文字や記号、あるいは図形等を表示させることができるが、2枚の導光板は、接触しないように、どちらか一方の導光板には、樹脂で図形等を書いたり印刷等をした塗膜で隔てている。
【0006】
【作用】
本発明は、以上のように構成された装置であるから、常に文字や図形、あるいは絵等を、導光板と盲板の間、あるいは導光板と導光板の間で、表示させることができる。また、塗膜の厚みで、導光板と盲板、あるいは導光板と導光板は、接触しない間隔を保つことができるので、薄くて、明瞭に文字や図形を表示する表示板とすることができる。
【0007】
【実施例】
第1図と第2図は、本発明の一実施例である。第1図は正面図であり、第2図は側面図である。光源1は、ケース4の上部と下部に取り付けてあり、光源1が発した光は、導光板2の内部に導光されるようになっている。導光板2の表面に文字や図形を印刷した面を2bとして、その反対面を2aとする。導光板の面2bには、図形を印刷した塗膜5が形成してあり、塗膜5は、盲板3の表面とも接している。塗膜5は、樹脂塗料を材料とした塗膜を数十マイクロメーターから数百マイクロメーター程度の厚みで印刷してあり、導光板2と盲板3が接触しないように仕切っている。導光板2に導光した光は、面2bに印刷した塗膜5で反射するから、図形を明瞭に表示することができる。また、導光板2の面2aに、文字や記号等を蛍光ペン等で書くと、導光した光によって明るく表示する表示板となる。
【0008】
【発明の効果】
この実施例では、導光板2と盲板3の接触を塗膜5で仕切ることにより、導光板2の2b面に印刷した塗膜5と、2a面に書込みされた図形や文字等の両面を明るく表示できる表示板となる。

[Industrial application fields]
The present invention relates to a display device using a light guide plate.
[0002]
[Prior art]
Conventionally, in a light guide plate display device, an ink or a fluorescent pen or the like is written on the surface of a light guide plate to display a figure or a character, and the light guide plate and the blind plate are kept in contact with each other while being kept in contact with each other. However, in this method, if the distance between the light guide plate and the blind plate is narrowed, if the light guide plate or the blind plate is bent or warped, there is a possibility of contact, and characters to be displayed are written on the surface of the light guide plate. The pressure bent the light guide plate, making it easier to contact the blind plate. From the above, it has been difficult to produce a thin display panel by narrowing the distance between the light guide plate and the blind plate.
[0003]
[Problems to be solved by the invention]
In the present invention, when the light guide plate and the blind plate come into contact with each other, the light guided through the light guide plate at the contacted portion shines strongly, so that the contact is prevented. Further, when the light guide plate and the blind plate are brought into close contact with each other, it is intended to solve the disadvantage that characters written on the surface of the light guide plate cannot be clearly displayed. Even if the light guide plate is replaced with the light guide plate, the light guiding the light guide plate radiates to the outside when the two light guide plates come into contact. was there.
[0004]
[Means for Solving the Problems]
To explain the means for solving the above-mentioned purpose, in order to create a gap between the light guide plate and the blind plate, the character, figure or picture to be displayed is printed or written with the thickness of the coating film of resin or the like. It is separated. About resin etc., you may use an adhesive agent or ink other than a coating material.
[0005]
Resin, etc. for writing graphics or printing on the blind plate, using a material that retains elasticity even when dried, is displayed by light guided to the light guide plate when it is in close contact with the surface of the light guide plate Characters and figures can be displayed clearly. By replacing the blind plate with a light guide plate, it is possible to always display characters, figures or pictures between the two light guide plates. In this case, even the light guide plate replaced with the blind plate can display characters, symbols or figures written on the surface with the light guided from the light source, but the two light guide plates do not contact each other. As described above, one of the light guide plates is separated by a coating film on which a figure or the like is written or printed with a resin.
[0006]
[Action]
Since the present invention is an apparatus configured as described above, it is possible to always display characters, figures, pictures or the like between the light guide plate and the blind plate or between the light guide plate and the light guide plate. Moreover, since the light guide plate and the blind plate, or the light guide plate and the light guide plate can be kept away from each other by the thickness of the coating film, the display plate can be made thin and clearly display characters and figures. .
