Abstract: A display device, including a flexible substrate, multiple lighting units, and multiple signal lines, is provided. The lighting units and the signal lines are located on the flexible substrate, and the signal lines are respectively electrically connected to the lighting units. Each signal line includes multiple first conductive patterns, at least one second conductive pattern, and at least one third conductive pattern. The first conductive patterns are located on the flexible substrate. The second conductive pattern is located on the first conductive patterns, and two ends of each second conductive pattern are respectively connected to two first conductive patterns. In a stretched state, the two first conductive patterns twist the commonly connected second conductive pattern. The third conductive pattern is superimposed on the second conductive pattern.

Abstract: A file-opening system and method are disclosed herein. The method is applied to a network system. The network system includes a local device and a server. The method includes: requesting and receiving a remote application list and supported types of a remote application; modifying at least one file association setting stored in the local device according to the remote application list and the supported types of the remote application; receiving a user command corresponding to a local file in the local device and transmitting a file-opening request to the server, such that the server execute the local file by the remote application according to the file-opening request; and, receiving a real time video of the remote application executing the local file transmitted from the server with streaming protocol and displaying the real time video of the remote application.
