Description
Technical Field
The invention relates to the technical field of electronic equipment, in particular to multifunctional electronic equipment capable of orderly starting and a starting method thereof.
Background
Portable electrical devices, such as portable electrical computing devices, have become an essential tool in both private and professional settings. Examples of such portable appliance computing devices include multi-function handsets (so-called "smart" phones), laptops, electronic book readers, tablets, head-mounted theaters, and other similar portable devices. These devices typically include a display unit, a portable power supply, a power-on key, various user input features, and a signal processing unit, among other devices. In some cases, these devices also include wireless transmission functionality for sending and receiving data. With the development of the technology, the function units of the portable electrical devices are more and more, and the power on/off mode controlled by one key through one power on/off key can cause the function units including the display unit and the signal processing unit to be powered on simultaneously, so that the signals are disordered, and the function units cannot achieve correct or stable starting operation, for example, the display unit cannot display correctly or stably.
A head mounted cinema (HMD) is a kind of head mounted virtual display, and belongs to a kind of head mounted portable electrical equipment, also called glasses type display, portable cinema, and mobile cinema. Since the glasses type display external image glasses are also called video glasses (video glasses) by the image, while displaying the video image of the audio/video player exclusively for a large screen. Although the specific characteristics of a head-mounted theater may vary, in many instances a range of functions may be provided, such as checking email, reading news, browsing the internet, watching movies and video, displaying photos and graphics, playing games, and so forth. But generally comprises two functional units: the mobile phone comprises a signal processing unit and a display unit, wherein the two units are generally connected through an MHL cable and are turned on and turned off through the same power key, and the signal processing unit generally comprises a system management module, a display processing module and a display output module. The boot process of the head-mounted cinema is generally that the display processing module is started after the system management module is stable. And the display output module needs to start after the initialization of the display unit is completed, send interactive information to the display unit and then output a display signal. And then the display unit processes the display signal sent by the signal processing unit and displays the display signal correctly. Because the signal processing unit and the display unit respectively have their own initialization mechanisms, the initialization sequence of the signal processing unit and the display unit needs to be coordinated simultaneously when the head-mounted cinema display unit is started, so that the image can be correctly displayed on the display screen of the display unit of the head-mounted cinema. Therefore, when the head-mounted cinema is started by one key through the start key, the display unit and the signal processing unit are started at the same time easily, so that signal confusion is caused, and the display unit cannot correctly or stably display images or videos.
Therefore, a new multifunctional electronic device and a booting method thereof are needed to avoid the above-mentioned drawbacks.

In this embodiment, the signal processing unit 10 includes an electronic switch 106, a main control module 101 (which may be an MCU), a signal processing module 104, and a signal output module 103, where the main control module 101 initializes when the main power-on key 102 is in an active state (i.e., can transmit power to the main control module 101), and the main control module 101 can control the electronic switch 106 to be turned on after initialization is completed, so that power can be transmitted to the function unit 20. The power receiving path of the functional unit 20 is substantially realized by the electronic switch 106 controlled by the main control module 101 and the mechanical auxiliary power switch 202. The signal processing module 104 may receive and process external signal source data through wired transmission or wireless transmission.
