Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for presenting display content on a display of a computing system. A method includes selecting, from a collection of luminance profiles (308) that are each configured to reduce brightness of the display content in different manners, a first luminance profile based on the current display brightness setting (320), the first luminance profile specifying a first amount of brightness reduction to a peripheral portion of the display content and a first gradient of brightness reduction for a portion of the display content between the peripheral portion of the display content and a center portion of the display content; applying the first luminance profile to the display content to modify the display content by reducing a brightness of the display content according to the first luminance profile; and presenting the display content on the display.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for enabling a variable refresh rate on a display. One of the methods includes receiving, from a content presentation device, a first signal set to a first value; completing generation of first visual content; and after completing the generation of the first visual content, determining that the first signal is set to the first value and a second threshold duration of time has not expired; sending, to the content presentation device, the first visual content, wherein sending the first visual content causes the content presentation device to change the first signal from the first value to the second value; and after sending the first visual content, receiving, from the content presentation device, the first signal set to the second value.

Abstract: A method includes: (a) receiving initial image frame data to display an image frame on a display panel, a luminance of each pixel of the display corresponding to a gray level; (b) identifying dark pixels at or below a first threshold gray level; (c) identifying pixels to be modified as a subset of the dark pixels neighbored by at least one bright pixel exceeding a second threshold gray level; (d) increasing by an incremental amount the gray level of the pixels to be modified, providing modified image frame data composed of: (i) the dark pixels that are neighbored by at least one bright pixel having gray levels that have been increased by the incremental gray level amount, and (ii) other pixels that have gray levels from the initial image frame data; and (e) displaying the image frame using the modified image frame data.

Abstract: This document describes techniques and apparatuses for performing color calibration of display modules using a reduced number of display characteristic measurements. In aspects, methods include generating a measured lookup table (50) for a source display module (32), using dynamic optimization to down-sample the measured lookup table and select a set of color patches, sending the color patches to a testing display module; measuring output values for the testing display module; generating a sparse lookup table (52) relating the color patches and the measured output values, up-sampling the sparse lookup table to a forward lookup table (54), and inverting the forward lookup table to generate a reverse lookup table (56). The reverse lookup table (56) can be utilized to determine correct output values (29) for driving a target display module to generate color lights within a display module color gamut.
