Abstract:
1. A method for providing image stability in a liquid crystal display (LCD) device, comprising: providing a first display image to a plurality of pixel elements of the LCD at a first time, where the first display image includes a first pixel in an on state; transitioning the on state of the first pixel to an off state, during a refresh cycle of the first display image; transitioning the off state of the first pixel back to the on state during a next sequential refresh cycle of the first display image; and providing a second display image to the plurality of the pixel elements of the LCD at a second time subsequent to the first time, where the second display image includes a second pixel in an on state and the first pixel in the off state wherein the second pixel is adjacent to the first pixel; transitioning the on state of the second pixel to an off state during the refresh cycle of the second display image; transitioning the off state of the second pixel back to the on state during the next subsequent refresh cycle of the second display image; transitioning the first display image to the second display occurs when both the first pixel and the second pixel are in or transitioning to the off state; and producing an area of brightness in the LCD with the first pixel and the second pixel that has a consistent repeating pattern of luminance for each refresh cycle such that the consistent repeating pattern of luminance for each refresh cycle produces a perception of consistent luminance for each refresh cycle.
