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.

摘要： A multi-screen display device of the present invention includes a master liquid crystal display device and one or more slave liquid crystal display devices which are mutually communicable with each other. Each of the liquid crystal display devices includes an LCD panel, a brightness sensor, brightness adjustment value adjustment means, and backlight control means. The brightness sensor is provided on a rear face side of the LCD panel, and detects the brightness of a backlight. The brightness adjustment value adjustment means adjusts a brightness adjustment value based on a result of comparison between a brightness measured by the brightness sensor and target brightness. The backlight control means adjusts the brightness of the LCD panel by controlling a time period for lighting the backlight based on the brightness adjustment value. The master liquid crystal display device further has target brightness adjustment means for receiving the brightness adjustment values from the slave liquid crystal display devices and adjusting the target brightness based on the brightness adjustment values of all of said liquid crystal display devices including the master liquid crystal display device itself.
