Abstract
Description
【発明の詳細な説明】 産業上の利用分野 本発明は液晶照明装置に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to a liquid crystal lighting device.
従来の技術
一般に液晶パネルを駆動させる信号は方形波であるため
、ラジオ受信機にノイズを輻射する。そのノイズを抑圧
するために、液晶部分をシールドする事が必要であシ、
今までは第４図に示すように液晶パネル１と反射板２の
全体をシールド７で覆っていた。2. Description of the Related Art Generally, the signal for driving a liquid crystal panel is a square wave, which radiates noise to a radio receiver. In order to suppress that noise, it is necessary to shield the liquid crystal part.
Until now, the entire liquid crystal panel 1 and reflector 2 have been covered with a shield 7, as shown in FIG.
発明が解決しようとする問題点
しかしながら上記のような構成ではシールド板が別にい
る為、液晶パネル部分の構造が複雑になるのと、別シー
ルドの分、コスト高となる問題点を有していた。Problems to be Solved by the Invention However, in the above configuration, the shield plate is separate, which makes the structure of the liquid crystal panel complicated, and the separate shield increases the cost. .
本発明ではこのような従来の問題点を解消するものであ
り、液晶パネルの照明に必要な反射板を用いてシールド
する液晶照明装置を提供するものである。The present invention solves these conventional problems and provides a liquid crystal lighting device that uses a reflective plate necessary for illuminating a liquid crystal panel to shield the liquid crystal panel.
問題点を解決するための手段
本発明の液晶照明装置は、液晶パネルと液晶照明に必要
な反射板にメッキ処理を施した物をアースするように構
成したことを特長とするものであるＯ
作 用
本発明の液晶照明装置はメッキを施した反射板が、ノイ
ズ抑圧の為のシールドとして効果が得られることによっ
て別のシールド板を省略できるものである。Means for Solving the Problems The liquid crystal lighting device of the present invention is characterized in that the liquid crystal panel and the reflective plate necessary for liquid crystal lighting are grounded. In the liquid crystal lighting device of the present invention, the plated reflector is effective as a shield for suppressing noise, so that a separate shield plate can be omitted.
実施例
以下本発明の一実施例の液晶照明装置について、図面を
参照しながら説明する。Embodiment Hereinafter, a liquid crystal lighting device according to an embodiment of the present invention will be described with reference to the drawings.
