摘要： A multi-screen display apparatus is a multi-screen display apparatus in which screens of a master apparatus and slave apparatuses are arranged. Each of the master apparatus and the slave apparatuses includes a light source for three primary colors formed of a semiconductor light emitting element, and a memory circuit for storing a brightness corresponding to a control current that is specific to each of the primary colors of the light source. The master apparatus determines a common target brightness based on the brightness outputtable by the master apparatus itself and the brightnesses outputtable by other apparatuses. Each of the master apparatus and the slave apparatuses reads, as a target control current, the control current corresponding to the target brightness from the memory circuit, and supplies the target control current to the light source.
