Description
【発明の詳細な説明】 産業上の利用分野 この発明は、液晶表示板を有する表示装置に関する。[Detailed description of the invention] Industrial applications The present invention relates to a display device having a liquid crystal display panel.
従来の技術
従来、金属材により形成された箱体の前面開口部に液晶
表示板を１茨合し、箱体の背面に設けた光源から液晶表
示板等に光線を照射して画像を表示するようにしたもの
が存する。Conventional technology Conventionally, a single liquid crystal display panel is attached to the front opening of a box made of metal material, and an image is displayed by shining light onto the liquid crystal display panel from a light source provided at the back of the box. There is something that did this.
発明が解決しようとする間居点
しかし、光源からの光線を箱体の一部が遮るので、液晶
表示板に明暗ムラを生じる。However, since a portion of the box blocks the light rays from the light source, uneven brightness occurs on the liquid crystal display panel.
この発明はこのような点に鑑みなされたもので、液晶表
示板の輝度を均一にすることができる表示装置をうるこ
とを目的とする。The present invention has been made in view of the above points, and an object of the present invention is to provide a display device that can make the brightness of a liquid crystal display panel uniform.
間悪点を解決するための手段
一対の反射板を有し背面が光源に対向し前面に液晶表示
板が保持される枠体をもうけ、この枠体の前記反射板以
外の部材を透光性を有する材料により形成する。Means for Solving the Disadvantageous Problems by Providing a frame body having a pair of reflective plates, the back side facing the light source, and holding the liquid crystal display panel on the front side, and making the members of this frame body other than the reflective plates translucent. It is formed from a material that has
作用
したがって、光源からの光線は遮られることなく液晶表
示板に照射され、）即度を均一にする。Therefore, the light rays from the light source are irradiated onto the liquid crystal display panel without being blocked, making the light intensity uniform.
実施例 この発明の一実施例を図面に基づいて説明する。Example An embodiment of this invention will be described based on the drawings.
１は枠体である。この枠体１は、それぞれアクリル樹脂
等の透光性を有する材料により形成された前面パネル２
と上下一対の横長の補強板３と複数の補強板４とを組立
て、さらに内面に反射面５を有して補強板４を挾持する
一対のアルミ製の反射板６を組立たもので、背面には光
源７に対向する開口部８が形成されている。前面パネル
２には多数の液晶表示素子９を並設してなる液晶表示板
１０が固定されている。なお、反射板６の外面には液晶
表示板１０に接続されたフレキシブルＰＣ板１１が設け
られている。1 is a frame. This frame body 1 includes a front panel 2 made of a translucent material such as acrylic resin.
A pair of upper and lower horizontally elongated reinforcing plates 3 and a plurality of reinforcing plates 4 are assembled, and a pair of aluminum reflecting plates 6 having reflective surfaces 5 on the inner surface and holding the reinforcing plates 4 are assembled. An opening 8 facing the light source 7 is formed in the opening 8 . A liquid crystal display board 10 having a large number of liquid crystal display elements 9 arranged side by side is fixed to the front panel 2. Note that a flexible PC board 11 connected to a liquid crystal display board 10 is provided on the outer surface of the reflection plate 6.
このような枠体１は縦横に積み重ねられて並設されてい
る。Such frames 1 are stacked vertically and horizontally and arranged in parallel.
このような構成において、光源７から光線を照射して液
晶表示板１ｏに画像を形成するが、補強板３．４が透光
性を有する材料により形成されているため、光源７から
照射させる光線は枠体１の一部に遮られることなく照射
される。したがって、液晶表示板１０に明暗ムラが生じ
ることがなく、輝度を均一にすることができる。In such a configuration, an image is formed on the liquid crystal display panel 1o by irradiating the light beam from the light source 7, but since the reinforcing plate 3.4 is formed of a translucent material, the light beam irradiated from the light source 7 is irradiated without being blocked by a part of the frame 1. Therefore, uneven brightness does not occur on the liquid crystal display panel 10, and the brightness can be made uniform.
発明の効果
この発明は上述のように構成したので、光源からの光線
は枠体の構成部材に遮られる二となく液晶表示板に照射
されるため、輝度を均一にして表示画質を向上させるこ
とができる効果を有する。Effects of the Invention Since the present invention is constructed as described above, the light rays from the light source are irradiated onto the liquid crystal display panel without being blocked by the constituent members of the frame body, so that the brightness can be made uniform and the display image quality can be improved. It has the effect of
図面はこの発明の一実施例を示すもので、第１図は斜視
図、第２図は枠体を積み重ねた状態を示す縦断側面図で
ある。The drawings show an embodiment of the present invention, and FIG. 1 is a perspective view, and FIG. 2 is a longitudinal sectional side view showing a state in which the frames are stacked.
Claims (1)
反射面を有するとともに背面に光源と対向する開口部が
形成され前面に液晶表示板が保持される枠体を設け、こ
の枠体の前記反射板以外の部材を透光性を有する材料に
より形成したことを特徴とする表示装置。A frame body is provided, which has a reflective surface formed on the inner surface and a pair of reflective surfaces facing each other with an interval, an opening facing the light source is formed on the back surface, and a liquid crystal display panel is held on the front surface. A display device characterized in that members other than the reflecting plate are formed of a material having translucency.
