摘要

A display method is applicable for a display apparatus. The display method includes transmitting preview data outputted by a client terminal to a host terminal such that the host terminal displays a preview image corresponding to the preview data. After the host terminal displays the preview image, if the host terminal outputs a first display permission signal, the display apparatus is utilized to display an image corresponding to an image signal outputted by the client terminal.

主权项

1. A display apparatus, comprising:
a display unit; and a processing module electrically connected with the display unit, wherein the processing module is configured to transmit preview data outputted by a client terminal to a host terminal before the display unit displays an image corresponding to an image signal outputted by the client terminal; the processing module is further configured to receive a first preview request outputted by the host terminal and output a second preview request to the client terminal according to the first preview request such that the client terminal outputs the preview data to the processing module according to the second preview request, the processing module then transmits the preview data to the host terminal; after the processing module transmits the preview data to the host terminal, if the processing module receives a first display permission signal outputted by the host terminal, the processing module is further configured to output a second display permission signal to the client terminal according to the first display permission signal such that the client terminal outputs the image signal to the processing module according to the second display permission signal; and the processing module is further configured to control the display unit to display the corresponding image according to the image signal.
