Abstract
(57)【要約】本公報は電子出願前の出願データであるた
め要約のデータは記録されません。(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.
Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はＣＥＬＴ表示装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a CELT display device.
従来、この種のＣＲＴ表示装＠、は、必要のない時でも
輝度が一定のままとなっていた。Conventionally, in this type of CRT display device, the brightness remained constant even when it was not needed.
〔発明が解決しようとする問題点」
上述した従来のＣＲＴ表示表示装弾度が一定となってい
るのでＣＲＴの常時表示エリアが焼ける、不用な電力を
消費する、寿命が短くなるという欠点がある。[Problems to be Solved by the Invention] Since the above-mentioned conventional CRT display has a constant display elasticity, there are drawbacks such as the constant display area of the CRT being burnt out, unnecessary power consumption, and shortened lifespan.
〔問題点を解決するための手段」
本発明のＣＲＴ表示装！Ｒは警報等の自動表示や人間が
操作して使用した後、一定時間たつとＣＲＴの輝度が下
がる手段を有している。[Means for solving the problems] CRT display device of the present invention! R has a means for automatically displaying alarms and the like, and for reducing the brightness of the CRT after a certain period of time has elapsed after it has been operated and used by a human.
次に本発明について■面を参照して説明する。 Next, the present invention will be explained with reference to side ①.
図は本発明のブロック図である。ＣＲＴ表示装置は、Ｃ
ＲＴ、ＫＢ及びＣＲＴ制御部から構成され、ＣＲＴ制御
部は８ＩＦｔ−経由して外部機構と接続されている。The figure is a block diagram of the present invention. CRT display device is C
It is composed of RT, KB, and CRT control sections, and the CRT control section is connected to an external mechanism via 8IFt-.
警報が自動表示する場合は外部機器から８ＩＰを経由し
て警報が入力され、ＣＰＵで処理された後映像信号発生
部を通じてＣＢ、Ｔ＆Ｃ表示される。When an alarm is automatically displayed, the alarm is input from an external device via 8IP, processed by the CPU, and then displayed on the CB, T&C through the video signal generator.
また人間がＫＢを操作した場合もＣＰＵで処理された後
、同様にしてＣＲＴに表示される。Also, when a person operates the KB, the data is processed by the CPU and then displayed on the CRT in the same way.
そこで、ＣＲＴに何か表示した後、ＣＰＵで一定時間経
過したことを検知した場合、輝度信号発生部を通じてＣ
ＲＴの輝度を下げる。再び表示する場合も輝度信号発生
部を通じてＣＲＴの輝度を上げた後表示する。Therefore, when the CPU detects that a certain period of time has elapsed after something is displayed on the CRT, the
Decrease the brightness of RT. When displaying again, the brightness of the CRT is increased through the brightness signal generator and then displayed.
以上説明したように本発明は、必要でない時にＣＲＴの
輝度を下げることにエリＣＲＴの焼きっけを防止する、
電気の消費量を少なくする、寿命を長くするという効果
がある。As explained above, the present invention prevents burn-out of a CRT by lowering the brightness of the CRT when it is not necessary.
It has the effect of reducing electricity consumption and extending life.
