IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD
First Claim
1. An image display device of multi-display type, comprising:
- a plurality of image display sections each including a display panel, a backlight, and a local control section configured to perform area-active driving; and
a global control section configured to transmit and receive control information to and from the local control sections, wherein;
the local control sections each determine local control information and transmit the local control information to the global control section, the local control information being control information used when area-active driving is performed individually,the global control section determines global control information on the basis of the pieces of local control information received from the local control sections and transmits the global control information to the local control sections, the global control information being control information for the entire device, andthe local control sections each operate on the basis of the global control information received from the global control section.

Abstract
Control sections of displays 11 each determine control information Pi used when area-active driving is performed individually and transmit the control information Pi to a multi-display control section 12. The multi-display control section 12 determines control information Ps for the entire device on the basis of the received pieces of control information Pi and transmits the control information Ps to the control sections of the displays 11. All the displays 11 perform area-active driving on the basis of the same control information Ps. In this way, occurrence of a luminance difference or chromaticity difference among display screens of the displays 11 is prevented and the quality of a displayed image is improved.

12. An image display method of multi-display type using a plurality of image display sections each including a display panel, a backlight, and a local control section;
- and a global control section, the image display method comprising;
a step of, with each of the local control sections, determining local control information and transmitting the local control information to the global control section, the local control information being control information used when area-active driving is performed individually; a step of, with the global control section, determining global control information on the basis of the pieces of local control information received from the local control sections and transmitting the global control information to the local control sections, the global control information being control information for the entire device; and a step of, with each of the local control sections, performing area-active driving on the basis of the global control information received from the global control section.
- and a global control section, the image display method comprising;
