摘要： A method of processing image data for display on a display device having a multi-primary image display panel (2) comprises receiving image data constituting an image for display on the image display panel. In a first mode, signal voltages to be applied to sub-pixels of the image display panel are determined from the received image data and from a secondary data value for the pixel thereby to generate luminance variations perceivable at a first viewing position (5) but substantially not perceivable at a second viewing position (3). This provides a private display mode, since the luminance variations perceivable at the first viewing position (5) obscure the image from an observer at the first viewing position, while an observer at the second viewing position (3) is able to perceive the image since the luminance variations are not perceivable (or are substantially not perceivable) at the second viewing position In a second mode, signal voltages to be applied to sub-pixels of the image display panel may be determined just from the received image data thereby to generate an image perceivable at the first viewing position (5) and at the second viewing position (3). This provides a public or wide-view display mode.
摘要翻译：一种处理用于在具有多原色图像显示面板（2）的显示装置上显示的图像数据的方法包括：接收构成用于显示在图像显示面板上的图像的图像数据。在第一模式中，根据接收的图像数据和从像素的辅助数据值确定要施加到图像显示面板的子像素的信号电压，从而产生在第一观看位置（5）可感知的亮度变化，但是在第二观察位置（3）基本上不能察觉。这提供了私人显示模式，因为在第一观看位置（5）可感知的亮度变化使第一观看位置处的观察者的图像模糊，而第二观看位置（3）处的观察者能够感知图像，因为亮度变化在第二观察位置不可感知（或基本上不可察觉）在第二模式中，可以仅从接收的图像数据确定要施加到图像显示面板的子像素的信号电压，从而产生在第一观看位置（5）和第二观看位置（3）可感知的图像。这提供了公共或广视图显示模式。

摘要： A display device disclosed includes a liquid crystal panel (6), and an image optimization circuit (4) for switching, in accordance with an update frequency of image data, between (i) a first mode in which a liquid crystal driver (7) is driven at a first driving frequency and (ii) a second mode in which the liquid crystal driver (7) is driven at a second driving frequency lower than the first driving frequency. The display device can therefore be used even in a case where a transmission path for image data is limited and optimally display high-resolution image data with reduced electric power consumption.

摘要： A display device includes control electronics and a pixilated liquid crystal (LC) panel. The control electronics receives inputs of main image data for a main image and side image data for a side image. The control electronics outputs combined image data combining the main and side images such that an on-axis viewer perceives from the combined image the main image, and an off-axis viewer perceives from the combined image the side image. The output image data comprises data values chosen from a set of available output data values for the pixels selected from multiple sets of available data values depending on at least on the side image data. For a pixel currently being processed, the output data value is chosen from the selected set of available output data values for which a resulting luminance value is closest to a target luminance value for the current pixel.
