摘要： A method is provided for compensating for brightness change in a display. The method includes storing a plurality of look-up tables (LUTs), where each table has a plurality of pixel levels at a variable refresh rate (VRR) and a plurality of brightness signals that provide compensation for the brightness change when refresh rate is changed during a panel self-refresh (PSR). The method also includes receiving an input signal from a graphics processing unit (GPU) and determining the VRR of the input signal from the GPU. The method further includes obtaining the LUT at the determined VRR of the input signal and adjusting the input signal to produce an output signal that compensates for the brightness change for each pixel or sub-pixel in a timing controller based upon the LUT at the determined VRR. The method further includes transmitting the output signal to the display. A system is also provided.

摘要： The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

摘要： An electronic device may include a display and display control circuitry. The display may be calibrated to reduce color non-uniformity in the display. Display calibration information may be obtained during manufacturing and may be stored in the electronic device. The display calibration information may include color-specific, intensity-specific, location-specific correction factors. During operation of the display, display control circuitry may receive pixel data to be displayed by each pixel in the display. The pixel data may include color information and intensity information for each pixel.

摘要： An electronic device may be provided with a display. The display may include a backlight having an array of locally dimmable light sources. Control circuitry may provide control signals to the backlight to produce light at different brightness levels. When the brightness level is below a threshold, the control circuitry may use pulse-width-modulation control signals to control the light sources in the backlight. When the brightness level is above the brightness threshold, the control circuitry may use analog control signals to control the light sources in the backlight. The control circuitry may adjust the threshold to achieve different dimming ranges for different brightness settings. A low brightness setting, for example, may have a lower threshold and lower dimming range than a high brightness setting, which may help produce darker darks when the display operates in a low brightness setting.

摘要： Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.

摘要： An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The image frames may be displayed with positive and negative polarities to help reduce charge accumulation effects. A charge accumulation tracker may analyze the image frames to determine when there is a risk of excess charge accumulation. The charge accumulation tracker may analyze information on gray levels, frame duration, and frame polarity. The charge accumulation tracker may compute a charge accumulation metric for entire image frames or may process subregions of each frame separately. When subregions are processed separately, each subregion may be individually monitored for a risk of excess charge accumulation.
