顯示屏的耗電量怎么計算？

顯示屏的耗電量怎么計算？一平方大小耗電多少？

學(xué)習(xí)一下。。。。。。。。。。。。。。

全是笨蛋，功率=電壓X電流

萊鳥學(xué)習(xí)……請大家多少指點指點

大體上就是數(shù)數(shù)led的個數(shù)就行啊  比如是200個led  那么功耗就是200*15ma=3A  每個了點是2伏電壓 那就3*2=6w   實際的耗電量要比這個要高一點  因為各個原件和線路都有損耗  多以如果是200led的話就應(yīng)該是10w左右    不知道說的對否{:1_147:}

怎么測量啊  教一下吧

測量功率用功率表，或功率計

怎么測量啊  教一下吧 老大 {:1_118:}

可以實際測量一下{:1_106:}
