MULTI-DISPLAY SYSTEM
First Claim
1. A multi-display system comprising a multi-display screen formed by arranging a plurality of image display devices each having a display panel capable of displaying image information to lie side-by-side, the multi-display system comprising:
- a test pattern display controller that causes a plurality of predetermined display colors to be sequentially displayed in a predetermined display region on a periphery of each of the display panels;
a transmitting unit that constitutes a plurality of transmission channels each capable of transmitting an emitted light from the display region of each of the display panels;
a spectral characteristics detector that detects spectral characteristics of the emitted light transmitted by each of the transmission channels; and
an adjustment unit that adjusts, based on the spectral characteristics detected by the spectral characteristics detector, luminance and chromaticity of the image display device having the display panel that has outputted the emitted light having the spectral characteristics so that a difference from luminance and chromaticity of adjacent image display devices decreases.

Abstract
A multi-display system includes a test pattern display controller that causes a test pattern to be displayed in a predetermined display region on a periphery of an LCD module of each image display device, an optical transmitting unit that constitutes a plurality of transmission channels each capable of transmitting an emitted light from each of the display regions, a spectral radiance sensor that detects spectral characteristics of the emitted light transmitted by each of the transmission channels, and an adjustment unit that adjusts, based on the spectral characteristics detected by the spectral radiance sensor, luminance and chromaticity of the image display device having the LCD module that has outputted the emitted light having the spectral characteristics so that the difference from luminance and chromaticity of the adjacent image display devices decreases.
