    • A method of processing image data for display by a display panel of a display device comprises receiving image pixel data representing an image. In a first mode, the method performs a first mapping of the image pixel data to drive signals, each drive signal for driving a respective pixel or group of pixels of the display panel. The first mapping is arranged to produce an on-axis luminance pattern which is dependent mainly on the image pixel data and an off-axis luminance pattern which is wholly or substantially independent of the image pixel data. The first mapping is arranged, for a pixel or a group of pixels, to map the image pixel data for the pixel or group of pixels to one of a first plurality of preselected drive signals including at least first and second pre-selected drive signals that drive, in use, the pixel or group of pixels of the display panel to produce different on-axis luminance values and that drive, in use, the pixel or group of pixels of the display panel to produce the same or similar off-axis luminance values at at least one off-axis viewing angle. This provides a private display mode. If a public display mode is desired, a second mapping of the image pixel data to a second plurality of drive signals is performed instead of the first mapping. The second mapping is arranged to produce an on-axis luminance pattern which is dependent mainly on the image pixel data and an off-axis luminance pattern which is dependent mainly on the image pixel data.
    • 处理由显示装置的显示面板进行显示的图像数据的方法包括:接收表示图像的图像像素数据。 在第一模式中,该方法执行图像像素数据到驱动信号的第一映射,每个驱动信号用于驱动显示面板的相应像素或像素组。 第一映射被布置为产生主要依赖于图像像素数据的轴上亮度图案和完全或基本上独立于图像像素数据的离轴亮度图案。 布置第一映射,对于像素或一组像素,将像素或像素组的图像像素数据映射到包括至少第一和第二预选驱动信号的第一多个预选驱动信号中的一个,其中至少第一和第二预选驱动信号, 在使用中驱动显示面板的像素或像素组以产生不同的轴上亮度值,并且在使用中驱动显示面板的像素或像素组以产生相同或相似的离轴亮度 值在至少一个离轴视角。 这提供了一种私人显示模式。 如果需要公共显示模式,则执行图像像素数据到第二多个驱动信号的第二映射,而不是第一映射。 第二映射被布置为产生主要依赖于图像像素数据的轴上亮度图案和主要依赖于图像像素数据的离轴亮度图案。
