    摘要: A system, method, and computer program product are provided for determining a duty cycle for a pixel (e.g. of alternating pixel values to achieve an average pixel color). In use, a first value of a sub-color component bit of a pixel is determined. Additionally, a second value for the sub-color component bit of the pixel is calculated. Further, a duty cycle for alternating between the first value and the second value is determined (e.g. which when applied at normal display frame rate may achieve an average color).

    摘要: A method and system are implemented to measure quantitative changes in display frame content for dynamically controlling a display refresh rate. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of composing a first display frame from a first set of rendered image surfaces, composing a second display frame from a second set of rendered image surfaces, dividing the first display frame and the second display frame into a same number of frame regions. Also, for each of the frame regions, the method also includes the steps of calculating a first set of numerical codes and a second set of numerical codes representative of the content associated with the frame region in the first and second display frame, respectively; and determining an amount of changes in content between the first display frame and the second display frame based on the results of comparing the first set of numerical codes against the second set of numerical code.

    摘要: One embodiment of the present invention sets forth a technique for generating and transmitting video frame data from a graphics processing unit (GPU) to a color field sequential display device capable of displaying an auto-stereoscopic image. A frame buffer image comprising per-pixel packed color channels is transformed to a frame buffer image comprising regions corresponding to the color channels with vertical blanking regions inserted between color sub-field regions. Each region of the transformed frame buffer image is sequentially transmitted to the color field sequential display device for display of the corresponding color channel. Backlight illumination for each color channel is controlled by the GPU for temporal alignment with display of each color channel during the vertical blanking interval. The technique is compatible with lenticular and parallax barrier displays.

    摘要: A method and apparatus for performing display image refresh in bursts to a display device. A buffered refresh controller includes capabilities to drive the display based on video signals generated from a local frame buffer at a first rate. The graphics controller may optimally be configured to burst a new frame of pixel data to the buffered refresh controller at a second rate to replace the previous frame of pixel data in the local frame buffer. The second rate is different than the first rate. Additionally, the graphics controller may send frames only when they contain new pixel data. By enabling the graphics controller to selectively transmit the new frame of pixel data at the second rate, higher than the first rate, the graphics controller may be placed in a power-saving state during at least a portion of each frame update.

The method comprises detecting a system idle event, activating the frame buffer, and storing display information in the frame buffer from the graphics processor. The method further comprises initiating a power reduction state for the graphics processor, self-refreshing the display device during the power reduction state with the display information stored in the frame buffer, and initiating a system suspend comprising a power reduction state for the computer system provided the system agent detects the absence of disruptive software and system configurations.
