Abstract: Briefly, methods and apparatus provide image content to, and display image content on, displays with a variable refresh rate that reduce frame delays and avoid display image flickering problems. In one example, the methods and apparatus are operative to vary a display's refresh rate by varying a current frame's vertical blanking period by re-providing the current frame for display prior to providing a new frame for display. In this fashion, the displaying of a new frame may be advanced by assuring that a new frame can be provided for display as soon as it has been rendered and available for display. In addition, by re-providing the current frame for display prior to providing a new frame for display, new frames may be provided for display at rates within a safe rate range such that display image flickering issues are avoided or reduced.

Abstract translation: 简而言之，方法和装置以可减少帧延迟并避免显示图像闪烁问题的可变刷新速率为显示器提供图像内容和显示图像内容。 在一个示例中，方法和装置可操作以通过在提供用于显示的新帧之前重新提供用于显示的当前帧来改变当前帧的垂直消隐周期来改变显示器的刷新率。 以这种方式，可以通过确保新的帧可以被提供用于显示，一旦它被渲染并且可用于显示，就可以提高新帧的显示。 此外，通过在提供用于显示的新帧之前重新提供用于显示的当前帧，可以提供新帧以用于以安全速率范围内的速率显示，使得避免或减少显示图像闪烁问题。

Abstract: A method and apparatus for providing an image on a vertical scan panel determines whether a mode of operation for a vertical scan panel is either a scan conversion pass-through mode or a horizontal scan conversion mode. If the determined mode is the horizontal scan conversion mode, the method and apparatus converts display data in the vertical scan panel from a horizontal scan format to a vertical scan format and displays the converted display data on the vertical scan panel. However, if the determined mode is the scan conversion pass-through mode, the method and apparatus includes displaying display data on the vertical scan panel in a vertical scan format without applying a scan conversion operation on the display data.

Abstract translation: 用于在垂直扫描面板上提供图像的方法和装置确定垂直扫描面板的操作模式是扫描转换直通模式还是水平扫描转换模式。 如果确定的模式是水平扫描转换模式，则该方法和装置将垂直扫描面板中的显示数据从水平扫描格式转换为垂直扫描格式，并将转换的显示数据显示在垂直扫描面板上。 然而，如果所确定的模式是扫描转换直通模式，则该方法和装置包括以垂直扫描格式在垂直扫描面板上显示显示数据，而不对显示数据执行扫描转换操作。
