Abstract
一种负电压双电压电源驱动的LED显示屏，包括电源接口(10)和显示模组；电源接口(10)包括第一电极(11)、第二电极(12)和第三电极(13)；显示模组包括底板(20)，底板(20)上设接线端子(21)，接线端子(21)上设第一端口(22)、第二端口(23)和第三端口(24)；第一电极(11)通过第一线束(30)和第一端口(22)连接，第二电极(12)通过第二线束(31)和第二端口(23)连接，第三电极(13)通过第三线束(32)和第三端口(24)连接；第一电极(11)和第二电极(12)之间的电位差提供第一电压，第一电极(11)和第三电极(13)之间的电位差提供第二电压，第一电压和第二电压为显示模组供电。仅需要设置三个线束，即可为显示模组通过一个电源提供两个电压。占用空间较小，显示屏整体重量也有所降低。线束的减少还会降低电路自身的消耗，提高使用效率，节省电力资源。
