摘要： A display method and a related apparatus are disclosed. The display method is applied to an information interaction system. The information interaction system includes an electronic device (11) and a large-screen device (12). The method includes: The electronic device (11) obtains preset information, where the preset information includes information about an application installed on the electronic device (11), and the information about the application includes at least one of a name, an icon, and a package name of the application. The electronic device (11) generates a first window based on the preset information, where the first window includes any one of a plurality of desktops of the electronic device (11). The electronic device (11) sends the first window to the large-screen device (12), so that the large-screen device (12) displays a first user interface, where the first user interface includes the first window. This method can reduce an area that is occupied on a display of the large-screen device (12) by a projected window of the electronic device (11), and improve user experience.

摘要： A method for controlling a small screen window and a related device are provided. The method for controlling a small screen window includes: determining target blocked information, where the target blocked information includes indication information used to indicate that a target area of a first window is blocked by a second window, and the target area is a display area of a preset feature in the first window; determining a window display instruction based on the target blocked information, where the window display instruction includes an instruction for controlling one or more of a floating position of the second window on the first window, transparency of the second window, a size of the second window, and a shape of the second window; and controlling, according to the window display instruction, the second window to be displayed on the first window. According to the method, a small floating window can be more conveniently controlled and moved, so that the small floating window can intelligently avoid a special area. This improves user experience.

摘要： A motor driving apparatus is disclosed, including a driving circuit (201) outputting a three-phase alternating current and a main controller (202). The driving circuit (201) includes a U-phase electric driving circuit (2011), a V-phase electric driving circuit (2012), and a W-phase electric driving circuit (2013). Each of the electric driving circuits includes n storage batteries and n electric driving units in one-to-one correspondence with the n storage batteries. Signal ends of the n electric driving units are connected to the main controller (202), input ends of the n electric driving units are connected to the corresponding storage batteries, and output ends of the n electric driving units are cascaded to output one phase of the three-phase alternating current, where n is a positive integer. The main controller (202) determines, for each electric driving circuit in the driving circuit (201), an output voltage adjustment coefficient of each of the n electric driving units in the electric driving circuit based on voltages of the n storage batteries in the electric driving circuit, and outputs the output voltage adjustment coefficient to the corresponding electric driving unit. The apparatus can improve storage battery utilization.
