A liquid crystal display, an overdrive method and a memory are disclosed. The method includes steps of receiving a video source signal, and determining a real-time refresh frequency of the video source signal, obtaining overdrive values corresponding to at least two refresh frequencies of the liquid crystal display measured in advance, wherein the at least two refresh frequencies include a first refresh frequency and a second refresh frequency, and the real-time refresh frequency is greater than the first refresh frequency and less than the second refresh frequency, performing a linear interpolation according to the real-time refresh frequency, the first refresh frequency, a first overdrive value corresponding to the first refresh frequency, the second refresh frequency, and a second overdrive value corresponding to the second refresh frequency to obtain a real-time overdrive value corresponding to the real-time refresh frequency, and driving the liquid crystal display according to the real-time overdrive value.

Techniques for low-power self-refreshing of a display are disclosed. In the illustrative embodiment, a display receives frames as a base refresh rate, such as from a graphics processor. The graphics processor may determine that the last frame can be displayed for one or more additional frames and place the link to the display in a sleep state. The display can then refresh the last frame on the display. In order to save power, the display can refresh the last frame on the display at a reduced refresh rate, such as at the minimum refresh rate of the display.

A display control method and a display apparatus are provided. The display control method includes receiving a vertical synchronization signal, calculating a refresh rate according to the vertical synchronization signal, comparing the refresh rate with a threshold value to generate a comparison result, and generating a backlight control signal to control of a display panel of the display apparatus according to the comparison result.

In an embodiment, a method includes accessing a first rendered frame generated at a first frame rate. The method includes generating, based on the first rendered frame, one or more sub-frames at a second frame rate that is higher than the first frame rate. A first sub-frame of the one or more sub-frames is generated by determining a displacement measure associated with an anticipated movement of an optics component of a display system and applying, based on the displacement measure, one or more transformations to the first rendered frame to generate the first sub-frame. The first sub-frame is to be perceived by a user using the optics component of the display system. The method includes outputting the one or more sub-frames for display at the second frame rate. The one or more sub-frames are perceived by the user using the optics component of the display system.

A display device and a driving method thereof are disclosed. The display device includes a display panel, a processor and a driver; the driver includes a buffer; time for displaying one frame image includes display time and black insertion time. The driving method of the display device includes: outputting data for displaying one frame image which includes first subdata by the processor, and transmitting the first subdata to the buffer by the processor within the display time; and bufferring the first subdata by the buffer within the display time, and transmitting the first subdata to the display panel by the buffer within the black insertion time.

A timing controller, a display apparatus, and an operation method thereof are provided. The display apparatus includes a display panel and a timing controller. The timing controller includes a refresh mark controller and a pixel controller. The refresh mark controller includes a refresh mark table, and a plurality of refresh marks in the refresh mark table correspond to a plurality of sub-regions of a display region in the display panel. The refresh mark controller determines whether the sub-regions need to be refreshed according to an image signal and responds to a specific sub-region required to be refreshed to adjust a specific refresh mark according to a mapping ratio. The pixel controller sequentially looks up whether the refresh marks in the refresh mark table are adjusted, obtains the sub-regions corresponding to the adjusted refresh marks according to the mapping ratio, and performs a pixel refresh operation to the sub-regions.

A control chip configured to be coupled with a backlight driving chip and a display panel is provided. The control chip includes a storage element and a processing circuit. The storage element is configured to store a predetermined vertical refresh rate of the display panel. The processing circuit is coupled with the storage element, and is configured to provide a switching signal to the backlight driving chip so that the backlight driving chip enables a backlight module according to the switching signal. A frequency of the switching signal is equal to the predetermined vertical refresh rate. If the processing circuit has not received a vertical refresh starting pulse for more than a predetermined frame time corresponding to the predetermined vertical refresh rate, the processing circuit increases the frequency of the switching signal.

Technology for a display device is described. The display device can include at least one display screen operable to show at least one display panel. The display device can include a controller. The controller can receive a content frame from a content source over a transport topology. The controller can receive a presentation timestamp (PTS) associated with the content frame, where the PTS indicates an earliest time at which the content frame is to be displayed at the display device. The controller can provide the content frame for display on the display panel at a subsequent panel refresh opportunity in accordance with the PTS.

One embodiment provides for a display system to generate and display data on a display device, the display system comprising one or more graphics processors to generate one or more frames of data for display on the display device; a window manager to submit a request to display the one or more frames of data; a display engine to present the one or more frames of data to the display device for display; and display logic to receive the request to display the one or more frames of data and generate one or more display events for the display engine based on the request to display the one or more frames of data, wherein the display logic is to manage a set of statistics associated with the request.

A liquid crystal display device comprises a memory configured to store polarities of the source outputs from a source driver with respect to a panel self-refresh operation and a normal refresh operation that is not the panel self-refresh operation as a first inversion pattern and to store the polarities of source outputs with respect to a low refresh rate operation as a second inversion pattern; and an LRR controller configured to control the polarities of the source outputs with the first inversion pattern in panel self-refresh frames before the low refresh rate operation is performed, to control the polarities of the source outputs with a third inversion pattern referring to the first inversion pattern in low refresh rate frames in which the low refresh rate operation is performed, and to control the polarities of the source outputs with a fourth inversion pattern referring to the second inversion pattern in normal refresh frames after the low refresh rate operation ends.
