1. An apparatus comprising: first logic to analyze one or more image frames, to be displayed on a display device, the first logic to generate a first signal to indicate motion in at least one of the one or more image frames;second logic to generate a second signal to cause modification to a refresh
1. An apparatus comprising: first logic to analyze one or more image frames, to be displayed on a display device, the first logic to generate a first signal to indicate motion in at least one of the one or more image frames;second logic to generate a second signal to cause modification to a refresh rate of the display device from a first refresh rate to a second refresh rate based on: a change in power state associated with the display device and the first signal; andthird logic to determine whether to insert one or more additional interpolated image frames in a video stream formed by the one or more image frames,wherein the second logic is to generate the second signal based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 2. The apparatus of claim 1, wherein the one or more additional image frames comprise one or more black image frames. 3. The apparatus of claim 1, wherein the power state corresponds to a power state of a computing device that is coupled to the display device. 4. The apparatus of claim 1, further comprising one or more battery packs to supply power to the display device, wherein the power state corresponds to a charge level of the battery packs. 5. The apparatus of claim 1, comprising logic to cause the display device to switch from the first refresh rate to the second refresh rate during one of: a vertical blank period or a horizontal blank period. 6. The apparatus of claim 1, comprising logic to generate the second signal based on one or more of: analysis of image data corresponding to the plurality of frames, one or more capabilities of the display device, one or more selections, or a power setting. 7. The apparatus of claim 6, wherein the one or more selections comprise a user selection or an application selection. 8. The apparatus of claim 1, comprising logic to cause a display enable signal to be disregarded after the display device loses a lock of an incoming image signal. 9. The apparatus of claim 1, wherein the display device comprises a liquid crystal display, a plasma display, or a field emission display. 10. The apparatus of claim 1, comprising logic to determine whether a backlight of the display device is to be turned on or off. 11. A method comprising: generating a first signal in response to determining that motion exists in at least one of one or more image frames;determining change in a power state corresponding to a display device that is to display one of the one or more image frames;generating a second signal to cause modification to a refresh rate of the display device from a first refresh rate to a second refresh rate in response to the first signal and occurrence of change in the power state; anddetermining whether to insert one or more additional interpolated image frames in a video stream formed by the one or more image frames,wherein initiating the display refresh rate switching is performed based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 12. The method of claim 11, wherein the one or more additional image frames comprise one or more black image frames. 13. The method of claim 11, further comprising: analyzing the one or more image frames; anddetermining existence of motion in at least one of the one or more image frames based on the analyzing. 14. The method of claim 11, further comprising turning a backlight of the display device on or off. 15. The method of claim 11, wherein initiating the display refresh rate switching is performed based on one or more of: analysis of image data corresponding to the plurality of frames, one or more capabilities of the display device, one or more selections, or a power setting. 16. The method of claim 11, further comprising overdriving or underdriving a pixel of the display device based on a current value of the pixel and a previous value of the pixel. 17. A non-transitory computer-readable medium comprising one or more instructions that when executed on a processor configure the processor to: determine whether motion exists in at least one of one or more image frames;determine change in a power state corresponding to a display device that is to display the one or more image frames;cause switching of a refresh rate of the display device from a first refresh rate to a second refresh rate in response to a determination that motion exists in the one or more image frames and occurrence of change in the power state; anddetermine whether to insert one or more additional interpolated image frames in a video stream formed by the one or more image frames,wherein causing the display refresh rate switching is performed based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 18. The non-transitory computer-readable medium of claim 17, wherein the one or more additional image frames comprise one or more black image frames. 19. The non-transitory computer-readable medium of claim 17, further comprising one or more instructions that when executed on the processor configure the processor to overdrive or underdrive a pixel of the display device based on a current value of the pixel and a previous value of the pixel. 20. The apparatus of claim 1, wherein the first logic is to generate the one or more additional interpolated frames.
