Patent ID: 8179388

Claim:
A method, comprising: refreshing a display at a first rate in a first mode of operation, the first rate in the first mode of operation associated with a first number of blank pixel data sent to each line of the display; and transitioning to a second mode of operation for refreshing the display at a second rate, the second rate in the second mode of operation associated with a second number of blank pixel data sent to each line of the display, the second number of blank pixel data sent to each line of the display being greater than the first number of blank pixel data sent to each line of the display in the first mode of operation; wherein the second rate is a reduced refresh rate in comparison to the first rate, and visual manifestations associated with the transition are reduced during the transition by adjusting a blanking period of a display signal during the transition; wherein a number of active pixels in each line of the display is the same for both the first rate in the first mode of operation associated with the first number of blank pixel data sent to each line of the display and the second rate in the second mode of operation associated with the second number of blank pixel data sent to each line of the display, and a pixel clock is the same for both the first rate in the first mode of operation associated with the first number of blank pixel data sent to each line of the display and the second rate in the second mode of operation associated with the second number of blank pixel data sent to each line of the display.
