Aspects of the subject technology relate to pulsed backlight operation for a display backlight. Backlight pulse patterns are provided that include steady state pulse patterns to be applied during operation of a liquid crystal display unit of the display at a corresponding frame rate. The backlight pulse patterns can be arranged to prevent visible artifacts such as flicker or strobing, particularly at or near a transition between LCD frame rates. In some scenarios, transition pulse patterns are provided,

A display system is configured to convert Full-High Definition (FHD) image content into Ultra-High Definition (UHD) image content. The display system includes an interface configured to receive image content comprising a first resolution, such as FHD. The display system also includes a display device configured to display image content at a second resolution, such as UHD, the second resolution greater than the first resolution. The display system further includes one or more processors configured to: convert the image content from the first resolution to the second resolution; recover a spatial frequency of the converted image content as a function of a relative edge growth rate measured from the converted image content and an offline-determined relationship between the relative edge growth rates of the converted first image and its corresponding ground truth image; and provide the converted image content with the recovered spatial frequency to the display device.

A display system converts Full-High Definition (FHD) image content into Ultra-High Definition (UHD) image content. The display system includes an interface that provides image content to a display having a first resolution. The display system also includes a processor that converts an input image from a second resolution to the first resolution. The first resolution is greater than the second resolution. The processor generates a first value corresponding to a lost high-frequency component (HFC) of the input image; generates an initial component of an output image; selects a patch of the input image; estimates a lost HFC of the patch of the initial component based on a portion of the lost HFC of the input image that corresponds to the selected patch; and generates the output image based on a sum of the patch of the initial component and the estimated lost HFC of the patch of the initial component.
