摘要： Displays systems and methods for adjusting backlight illumination are disclosed wherein backlight illumination may be set low enough according to an error threshold amount in order to reduce backlight power consumption while maintaining a level of image quality. In one embodiment, image data is evaluated within a given frame and partitioned into histogram bins depending on the amount of backlight illumination requested or required by the image data. The histogram is traversed to provide an accumulative error measure. The error measure is compared against the error threshold and, if exceeded, the final backlight illumination may be set as a function of various illumination levels considered and possibly the first and a second threshold.

摘要： Display systems and methods for adjusting backlight illumination are disclosed for selecting a backlight illumination level that is low enough to reduce backlight power consumption while maintaining a desired level of image quality. The method 1) determines the peak illumination level requested by a frame to satisfy all pixels in a frame, 2) determines a histogram-based statistical illumination value for the frame, and 3) selects the lower of the two values. The histogram-based statistical illumination value is calculated using an error function for different ranges of illumination levels, wherein the error function correlates with luminance error introduced by selecting next lower range of illumination levels.

摘要： A display system (110) has a subpixel array (120) and a light source (140). In normal mode, image data (164) are processed by the display system to generate subpixel values (174) for the subpixels (130) and to generate a light source control value (BL) for the light source (140). In bypass mode suitable for testing new types of image-data processing, the subpixel values and the light source control value are generated by an external system (210) and are provided to the display system which is operated in bypass mode. The light source control value is not provided separately from the subpixel values but is encoded into some bits of the subpixel values for compatibility with older interfaces. The light source control value is encoded into the subpixel values' MSBs in case the subpixel values could be truncated. Other features are also provided.
摘要翻译：显示系统（110）具有子像素阵列（120）和光源（140）。在正常模式下，由显示系统处理图像数据（164），以生成子像素（130）的子像素值（174），并产生用于光源（140）的光源控制值（BL）。在适于测试新类型的图像数据处理的旁路模式中，子像素值和光源控制值由外部系统（210）产生，并被提供给以旁路模式操作的显示系统。光源控制值不是与子像素值分开提供，而是被编码成子像素值的一些位以与旧接口兼容。在子像素值可能被截断的情况下，光源控制值被编码为子像素值MSB。还提供其他功能。
