SPLICING SCREEN, METHOD FOR DETERMINING ADDRESS OF EACH SPLICING SCREEN UNIT AND MASTER CONTROL BOARD

摘要

The present disclosure provides a splicing screen, a method for determining an address of each splicing screen unit and a master control board. The splicing screen includes a plurality of splicing screen units which are spliced together. Each splicing screen unit includes a master control board, a gravity sensor coupled with the master control board, infrared emitters and infrared receivers. The infrared emitters and the infrared receivers are divided into four groups each including one infrared emitter and one infrared receiver; the four groups are at four sides including top, bottom, left and right sides of each splicing screen unit, respectively. At adjacent sides of adjacent two splicing screen units, two groups have an identical horizontal position or an identical vertical position. In adjacent two splicing screen units, signal is capable of being transmitted among infrared emitters and infrared receivers of only two groups at adjacent sides of adjacent two splicing screen units.
