Abstract: A display method and an electronic device that relate to the field of terminal technologies are provided. A first electronic device can obtain identification information of a plurality of second electronic devices- and establish a correspondence between a display region of the first electronic device and identification information of each second electronic device. Therefore, the second electronic devices can automatically display content in different display regions based on the correspondence. The method includes performing, by the first electronic device, sending a display configuration message, receiving identification information sent by a second electronic device, establishing a correspondence between a display region and the identification information, and sending the correspondence and displayed display content.
