1. liquid crystal indicator has:

  • According to incoming video signal show video liquid crystal panel,Shine this liquid crystal panel light source andDetect the brightness test section that surrounding brightness is used,Can regulation be changed with respect to the brilliance control characteristic of the luminosity of the said light source of at least one characteristic quantity of the brightness of relevant said incoming video signal corresponding to the detected brightness of this brightness test section, it is characterized in that,Corresponding to the detected lowering of luminance of said brightness test section, the luminosity with respect to the said light source of characteristic quantity is reduced,Simultaneously;

    Corresponding to the detected lowering of luminance of said brightness test section;

    The slope variation point that the makes said brilliance control characteristic direction that to be the feature change position of orderring reduce to the luminosity of said light source changes, and makes its direction that reduces to the zone that provides high-high brightness as the said characteristic quantity of the luminosity of said light source simultaneously or provides minimum brightness to change as the direction that the zone of the said characteristic quantity of the luminosity of said light source increases.
