Abstract
A multi-screen display apparatus has a lowest ABL level priority circuit which, receiving ABL signals from a plurality of display units constituting the display apparatus, provides a lowest ABL signal to the display units. At the presetting stage, while being supplied with the same video signal for a white picture, offset ABL voltages of the respective display units are adjusted to produce the uniform brightness over the entire multi-screen. The offset data thus determined are stored in the respective display units. When the display apparatus is in actual use, in each display unit the offset voltage is added to the lowest ABL voltage to produce an offset-added ABL voltage to be used for adjusting brightness and/or contrast of the display unit.
