Abstract

The invention provides a screen drawing method which is used for enabling screen display content data on second display equipment to be displayed on first display equipment. The method comprises the steps as follows: screen display content data sent from the second display equipment are received through network, and the screen display content data are data of screen display contents in changed screen areas of screen display areas of the second display equipment; the received screen display content data are used to cover a corresponding area of full-screen display content data duplicate stored in a storage device of the first display equipment; and the full-screen display content data duplicate obtained after covering processing is drawn on the main surface of the first display equipment for displaying. By adoption of the method, requirements on video memory can be lowered, Flip and other operations are reduced during the drawing process, and meanwhile, the situation that pictures need to be coordinated and matched between the two surfaces can be avoided.

Description

technical field [0001] The present invention relates to screen mirroring technology, and more specifically, to a screen description method and device. Background technique [0002] Screen mirroring technology refers to the technology of transmitting the screen display content of a device (such as a smartphone) to another device (such as a personal computer) for display. figure 1 A schematic diagram showing an application of the screen mirroring technology. Such as figure 1 As shown, the screen display content on the smart phone can be transmitted to the monitor of the personal computer via WiFi for display. [0003] figure 2 A flowchart showing the business process of the screen mirroring technology. Such as figure 2 As shown, in this business process, firstly, the content displayed on the screen is acquired on device A and encapsulated into a data packet. Then, transmit the encapsulated data packet to device B through network transmission (wireless transmission and / ...
