【电子显示屏成本计算】
电子显示屏成本的计算，我们就要考虑到他的组成1：单元板【ｐ１０单元板每块是16*32公分大小】
2：电源 【每块单元板需要【２-４安】电流１６*３２的单元板】
3：控制卡【根据你的需要选用，大马拉小车并不好】
4：边框【边上的型材 中间固定单元板的型材】
5：辅料【铜螺柱是调整距离的 磁脚是为了方便安装而使用的 排线是连接单元板控制卡用的 电源端子是为了方便显示屏接线用的，数据端子是方便接计算机用的 】
第一步：，确定自己需要多少单元板，例如，我的显示屏能放开的尺寸是2.4*0.4，那么2.4*0.32【单元板的长】=7.5由于只能放下2.4，那么我们选7，就是说7块单元板，因为单元板不嫩掰开用。{:1_114:} 高是0.4*0.16【单元板的高】=2.5 同样，我们选择2，这样，我们就计算出我们需要2*7=14块单元板，在我这里，单元板10张以上是80【有人也许说有做70的。是，我不和他比价格，没什么可比性，一味的追求低价，最后只能是砸自己的牌子】所以，我不准备和谁打价格站，如果你喜欢便宜的，就照70算，没什么的
第二步： 确定我们用多少板子后，我们就要选择控制卡了，
我的的板子是P10的，所以，我们的单元板是16*32点，也就是说一块的长着是32列，高着是16行，我们上个例子是14块单元板，就是说我们需要32*224点，照这样选择，90的USB卡就可以，在大我们需要64*1024的2009新卡。卡的价格从80-130不等
第三步，确定电源的大小，每块我们取中间电流值3安，14块需要42安，如果你很吝啬，用40安得也可以，不过要用品牌的，如果你很大方，不妨用2个40安的电源，我的电源的价格可以在我店里找到
第三，型材 ，型材不用留什么余量，当然，也不要缩水，16*32的长7块是224，高2块是32，我们裁224*2+32*2就可以了，，角铝是我们固定时需要的，当然，你要用磁脚的话就把角铝换成角铁吧，如果你傻到试图向铝上沾磁角，我也没什么好说的，角铝并不贵，也用不多，准备1根6米长的就够，好点的角铝在20元上下
第四，辅料，辅料大概就是固定螺丝，延长螺柱什么的，都不值钱，你照一块单元板2元准备就可以了，当然，如果你要用磁脚，就贵了，一块单元板要准备8元左右，另外，你要做全户外的话，就要准备一块玻璃，这都是钱啊，，毛毛啊，，，
第五，，，计算
成本===单元板+电源+控制卡+边框+辅料+日后的维修【5-10个点】+人工工资 学习学习，成本控制得好 看到这里，大家以后报价心里就有底了！！！ 控制软件呢...............——本文来自〖www.521LED.com〗原帖地址：http://www.521led.com/viewthread.php?tid=1075&fromuid=1155 是免费的 ***400;200;400,200;;** m48,19 l51,19,52,20,54,23,58,28,61,33,63,37,69,47,71,50,73,54,73,59 e|********* m63,58 l64,58,66,56,68,55,72,54,78,52,82,52,82,56,84,62,86,72,86,113,87,114,87,116,88,117,88,118,96,118,96,117,98,116,102,108 e|********* m119,21 l119,41,115,47,113,51,111,52,111,53,115,53,117,55,119,55,121,56,124,58,126,60,128,61,130,66,139,75,141,82,143,91,146,98,147,102,147,105,145,105 e|********* m162,53 l163,53,165,55,165,57,168,61,170,65,174,71,176,79,182,99,183,108,183,144,179,154,178,162,175,169,174,176,174,182,173,184,171,184,170,182,169,178,167,175 165,171,164,167,163,165,161,162,160,160 e|********* m156,75 l160,75 e|********* m158,89 l158,91,165,91 e|********* m113,120 l127,120,136,117,144,114,154,111,162,109,168,104,173,101,176,98,178,97 e|********* m200,67 l201,67,201,79,196,86,192,94,187,102,180,113,172,123,165,132,157,138,150,145,143,149,135,153,132,157,127,159,123,161,120,161 e|********* m216,118 l231,118,240,114,245,110,254,105,262,99,268,95,271,91,272,88,272,86,273,84,273,82 e|********* m257,70 l257,131,255,139,255,185,252,190,247,195,244,197,234,197,231,195,228,192,227,189,224,183,222,177,218,163,217,156 e|********* m223,142 l228,142,231,145,233,145 e|********* m369,113 l371,113,371,115,369,117,367,118,363,121,360,123,357,124,357,125,356,125,356,126,358,128,358,132,360,136,362,142,364,149,365,157,365,184,362,186,361,187,359,188 351,188,349,187,347,185,344,183,340,179,339,177,336,174,333,172,331,171,330,169,329,169,328,166,327,165 e|********* m337,108 l361,108,361,107,362,107,362,106,367,106,368,107,372,107,372,108,373,108,373,115,371,115,371,117,369,117,368,118 e 照老大这样算，这个屏的成本都在2500以上了，该卖多少钱啊？ 有谁见过条屏是按平方买的？ 我一定得看一看！！！！！！！！ 真的学习了 条屏是不是按字算钱啊 条屏是按什么来计算价钱的呀，老大能告诉我们吗，多谢了 ，我当地都是按米或个要钱，，，按平方碰见小的不是要赔？ 我每看一个贴，收益多多。 谢谢老大，学习了！！ 顶了厉害的！ 楼主辛苦了 学习中{:1_118:}{:1_144:} 不错
