The invention provides a method and system for processing a display frame in an Android WifiDisplay, and belongs to the field of display frame processing. The method for processing the display frame comprises the following steps that a frame synthesizing module puts the display frame in a far-end display frame buffer queue; a far-end display and processing thread reads the display frame, the display frame is put in a frame shared object, and a frame ready message is sent to a frame transfer thread; the frame transfer thread receives the frame ready message, the display frame is read from the frame shared object, the display frame starts to be processed, and then the display frame is sent to an encoding module to be encoded; the encoding module encodes the display frame, and the encoded display frame is delivered to a packaging and sending stroke; the packaging and sending thread carries out packaging, and sends the display frame to far-end display equipment. The interaction mode of the far-end display and processing thread and the frame transfer thread is changed, the delay phenomenon occurring when source end equipment and the far-end display equipment carry out display data transmission is effectively improved, and user experience is improved.
