Title:
MULTI-SCREEN DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2015200806
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-screen display device for suppressing a luminance difference between screens by switching a plurality of luminance modes.SOLUTION: In a multi-screen display device, a master image display device 101 of one of a plurality of image display devices is configured to set a common luminance mode as a luminance mode common to the plurality of image display devices for the plurality of image display devices, and to obtain luminance measured by a luminance sensor 10 from each of the plurality of image display devices, and to perform proper luminance determination for determining whether to reset the luminance mode set for the image display devices to another luminance mode on the basis of the comparison of the acquired luminance with the luminance proper range of the common luminance mode, and to, when the luminance mode of the image display devices is reset, obtain the luminance measured by the luminance sensor 10 again in each of the image display devices, and to perform the proper luminance determination again.
