简介： LED (Light Emitting Diode), is a solid-state semiconductor device that can convert electricity directly to Light; LED array is integrated on the MCU in the form of array. Its display generally has static and dynamic display two schemes. LED array control diode light-emitting principle: each light-emitting diode is placed on the intersection of the row line and the column line, when the corresponding row set 1 level, a column set 0 level, then the corresponding diode is bright; The input of the l
