Description
これによって、加熱調理器に搭載するLED表示器の各表示部のLED素子のOFF期間の間隔を調整でき、フリッカーを解消できる。
これによって、各LED表示部の輝度に応じてLED素子のOFF期間の間隔を調整でき、フリッカーを解消できる。
図1は、本発明の第1の実施の形態におけるLED表示器1のブロック図を示すものである。
COMのスキャンの5周期のうち、1周期目、3周期目、5周期目のCOM4がHi状態のときに、SEG1〜SEG5をONさせる。すると0表示が光って表示される。また、COMのスキャンの1周期〜5周期目でCOM5がHi状態のときに、SEG6をONさせる。するとmin表示が光って表示される。このときmin表示は、図2に示される7セグメントの一部である「表示部上5」等よりも面積が広いので、輝度をレベル5にする必要があり、7セグメントは、レベル3にすると、7セグメントとmin表示とが同じくらいの明るさに見えるようになる。さらに、7セグメントとmin表示が消灯している時間は5.5msecと2.5msecであるので、人間の目には感知できず、フリッカー現象は起こらない。
図5は、本発明の第2の実施の形態のLED表示器のフローチャートである。なお、実施例1と同一符号のものは同一構造を有し、説明は省略する。
