摘要： This disclosure provides systems, methods and apparatus for improving power efficiency of display devices. Control logic of a display device can use content adaptive backlight control (CABC) for displaying certain image frames with reduced illumination intensity. CABC can be used to determine a scaling factor for scaling up pixel values in an image frame and for scaling down the illumination intensity of a backlight used for illuminating the image frames. The control logic can determine a number of image subframes that have been rendered imperceptible to the human visual system (HVS) due to the reduced illumination intensity of the backlight, and refrain from displaying the determined number of image subframes. The control logic can utilize the additional time made available as a result of not displaying the determined number of subframes to further improve the power efficiency of the display device and/or improve image quality.

摘要： Prepared is brightness frequency data that indicates the number of pixels, having the same brightnesses in a brightness distribution for each of the fields represented by an input image signal. Based on the brightness frequency data, the number of subfields for emission at each brightness in a brightness region is adjusted for each of at least two brightness regions. As a result, the greater the frequency indicating the total number of pixels at each of the same brightnesses in a brightness region, the larger the number of subfields allocated to that brightness region. Therefore, satisfactory grayscale representation suitable to human visual characteristics is achieved.

摘要： A method for writing data to a display includes the steps of receiving a plurality of data bits, where each bit is associated with a different pixel of the display, reading the value of each data bit, determining whether each data bits has an off-state value, and generating a disable signal if each data bit has an off-state value. Responsive to a disable signal, the method further includes suspending the transfer of data to the pixels of the display, turning off a light source (e.g., an LED, laser, etc.) for a time period dependent on the significance of at least one of the data bits, and/or forcing each pixel of the display into an off state for a time period dependent on the significance of at least one of the data bits. A display driver circuit for performing the methods of the present invention is also disclosed.
