    • A display device is provided that comprises a liquid crystal display panel (2) for displaying an image by spatial light modulation. The image is represented by a plurality of image elements each having an image data value (7). The display device further comprises a display controller (1) arranged to determine a signal voltage to be applied to the panel (2) for each image element in dependence upon its image data value (7) and a secondary data value (8) for the element, there being a predetermined mapping between the data values and the signal voltage. The secondary data values (8) are arranged to vary across the image so as to introduce variations in luminance as a result of the mapping. The mapping and secondary data values (8) are mutually arranged to take account of the signal voltage to on-axis luminance response of the panel (2) so that the luminance variations introduced on-axis tend to balance locally through spatial averaging to, and hence would not be perceivable by, an on-axis viewer (3). The panel (2) furthermore has a non-linear off-axis luminance to on-axis luminance relationship, so that at least some of the luminance variations introduced off-axis do not balance locally through spatial averaging to, and hence would be perceivable by, an off-axis viewer (4).
    • 提供一种显示装置,其包括用于通过空间光调制显示图像的液晶显示面板(2)。 图像由具有图像数据值(7)的多个图像元素表示。 显示装置还包括显示控制器(1),其被布置为根据其图像数据值(7)确定要对每个图像元件施加到面板(2)的信号电压,以及用于所述第二数据值 在数据值和信号电压之间存在预定的映射。 辅助数据值(8)被布置成在图像上变化,以便作为映射的结果引入亮度的变化。 映射和次要数据值(8)被相互排列以考虑到面板(2)的轴上亮度响应的信号电压,使得在轴上引入的亮度变化趋向于通过空间平均来局部平衡到 因此不会被轴上观察者(3)察觉。 面板(2)还具有与轴上亮度关系的非线性离轴亮度,使得离轴引入的亮度变化中的至少一些在空间平均上不局部地平衡,因此可以被 ,离轴观察器(4)。
