QD

基本解释

Similarly, when the price is below p*, the quantity supplied qsis less than the quantity demanded qd.
同样的，当价格低于 p*时，供给数量qs 小于需求数量qd 。这将导致部分顾客买不到商品，将出现买家高价求购，卖家哄抬价格的局面。
Though QD Vision says a lot more work remains to be done before this display can be made commercially, it believes quantum-dot displays should end up being cheaper than OLED screens.
尽管QD Vision公司表示，在该显示器得以商业化之前还有大量的剩余工作要做，但它认为量子点显示器终将比有机发光两极管屏幕更便宜。
1 (Exercise) Ifdemand is given by qd(p) = a – bp, and supply is given by qs(p) = cp,solve for the equilibrium price and quantity. Find the consumer surplus and producer profits.
1（练习）如果需求函数为qd(p) = a – bp，供给函数为qs(p) = cp，求出均衡价格和均衡数量，以及消费者剩余和厂商利润。

Which brings us to the QD's other weakness - no camera, not even a camera attachment.
