Patent ID: 7944431

Claim:
A transmissive display device, comprising: a backlight, including a plurality of light emitting areas capable of controlling emitted-light luminances respectively; a transmission control panel for controlling transmittances for the light emitted from the backlight for display; emitted-light luminance setting means for setting emitted-light luminances in the light emitting areas of the backlight respectively; and transmittance setting means for setting the transmittances in pixels of the transmission control panel in accordance with the emitted-light luminances in the light emitting areas of the backlight respectively, the emitted-light luminance setting means: setting the emitted-light luminances such that either a difference between emitted-light luminances in adjacent emitting areas of the backlight or a ratio of the emitted-light luminances in the adjacent light emitting areas is not more than a tolerance value, including initial emitted-light luminance setting means for setting each of the emitted-light luminances of the light emitting areas of the backlight at an emitted-light luminance minimally required for display on a pixel with a maximum luminance in the light emitting area; and including emitted-light luminance correcting means for correcting the emitted-light luminances, set by the initial emitted-light luminance setting means, of the light emitting areas such that either the difference between the emitted-light luminances in the adjacent emitting areas or the ratio of the emitted-light luminances in the adjacent light emitting areas is not more than the tolerance value.
