OLED屏上。這樣在測(cè)量 LED大屏幕顯示器的時(shí)候只要把紅綠藍(lán)三種顏色的 LED發(fā)光二極管都點(diǎn)亮（即白色），就可直接分析出其中的顏色成分和亮度大小，并省去了大量的記錄工作，北京亮度計(jì)校準(zhǔn)。亮度計(jì)主要由五部分組成：數(shù)據(jù)采集模塊、MCU控制模塊、OLED顯示模塊、數(shù)據(jù)通信模塊、鍵盤輸入模塊。系統(tǒng)的基本工作原理為：通過鍵盤選擇顏色并設(shè)定參數(shù)，控制單片機(jī)來向傳感器發(fā)送指令，當(dāng)傳感器接收到光信號(hào)后，輸出頻率會(huì)隨之發(fā)生變化，單片機(jī)對(duì)傳感器采集的數(shù)據(jù)進(jìn)行適當(dāng)?shù)呐袛?、?jì)算和處理，北京亮度計(jì)校準(zhǔn)，北京亮度計(jì)校準(zhǔn)，然后數(shù)字化的顯示到
