【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

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
