[0043] like Figure 4 As shown, the wireless connection unit of the projection display and mobile charging integrated device can realize the wireless communication connection (such as Wi-Fi connection and Bluetooth connection) between the external electronic device and the projection display and mobile charging integrated device; the wireless charging module of the projection display and mobile charging integrated device can be used to wirelessly charge the external electronic device; the wired communication unit of the projection display and mobile charging integrated device can realize the wired communication connection (such as Type-C connection and USB connection) between the external electronic device and the projection display and mobile charging integrated device; the expandable interface of the projection display and mobile charging integrated device can be used to expand other peripherals in a diversified manner; the display driving unit of the projection display and mobile charging integrated device can realize the wireless / wired projection display function of the external electronic device, wherein the display driving unit can expand the display panel of various sizes and various resolutions; the touch control unit of the projection display and mobile charging integrated device can realize the switching control of the function key 4, and can also remotely control the external electronic device according to the touch signal detected from the touch screen.

[0044] For example, taking a mobile phone as an external electronic device, in the application scenario of using the rear camera of the mobile phone for ultra-high-definition selfies and live broadcasts, the projection display and reverse touch functions of the projection display and mobile charging integrated device play an important role. The specific working principle is as follows:

[0045] First, the mobile phone is connected to the integrated device for projection display and mobile charging by a wired or wireless connection method through the wired communication unit or wireless connection unit of the integrated device for projection display and mobile charging. The integrated device for projection display and mobile charging is started and enters the running state, the display panel lights up, and each functional module is initialized. The mobile phone system screen is captured and encoded by the mobile phone software, and the processed video signal is transmitted to the main control circuit unit of the integrated device for projection display and mobile charging through a wired communication link (such as USB, HDMI) or a wireless connection link (such as Wi-Fi, Bluetooth) based on Wi-Fi Direct, Airplay, DLNA, Miracast or related projection transmission protocols. After receiving the video signal data, the main control circuit unit transmits it to the image processor of the display drive unit for decoding and optimization. The decoded and optimized data is converted into a MIPI signal by the display controller, and the MIPI signal is transmitted to the display panel for display, thereby realizing the wired / wireless projection of the mobile phone, so that the user can view the ultra-high-definition image captured by the rear camera of the mobile phone through the display surface, and can take selfies and live broadcasts in a convenient way. Among them, wired screen projection can provide high-bandwidth and low-latency data transmission, ensuring image quality and real-time performance during the projection process, and is more suitable for scenarios requiring high stability and low latency; wireless screen projection does not require a data cable connection, is more convenient to use, and is suitable for various usage scenarios.

[0046] At the same time, users can perform touch operations on the touch screen of the integrated projection display and mobile charging device, such as adjusting the camera angle, switching camera modes, starting / stopping recording, switching applications, selfie buttons, content zooming, etc. The touch control unit can detect the touch signal corresponding to the touch operation, and transmit the touch signal to the main control circuit unit, and then transmit it to the mobile phone via Wi-Fi or Bluetooth. After receiving the touch signal, the mobile phone performs the corresponding operation, so that the mobile phone can be reversely controlled through the touch screen to make calls, send text messages, open applications, switch applications, take selfies, live broadcasts, zoom in and out of the screen, etc., to improve the convenience of operation and interactive experience. Among them, the touch screen can support a variety of gesture operations, such as sliding, zooming, rotating, etc., and users can quickly complete the operation through intuitive gestures. The touch control unit can accurately recognize these gesture operations and transmit the corresponding instructions to the mobile phone.

[0047] It should be noted that because the pixel of the rear camera of the mobile phone is higher than that of the front camera, users can use the screen projection function to take pictures with the rear camera instead of the front camera when taking selfies or live broadcasts. You can also fix the mobile phone on a stand and use the integrated screen projection display and mobile charging device to remotely view and reverse control the mobile phone.

[0048] Furthermore, the main control circuit unit of the integrated screen projection display and mobile charging device supports connecting to the local Wi-Fi network, and can provide high-speed and stable network connection to meet various user networking needs, such as system upgrades, application installation and updates, multi-device collaboration and other operations. Among them, multi-device collaboration can be applied to scenes such as live broadcasts and meetings. Users can use the collaboration of multiple integrated screen projection display and mobile charging devices to perform synchronous acquisition of multiple camera positions to improve video shooting effects and flexibility. In addition, the main control circuit unit of the integrated screen projection display and mobile charging device can also realize networking functions by connecting to mobile phone hotspots, so that users can still access the Internet through mobile phone hotspots and perform selfie live broadcasts and other operations without local Wi-Fi.

[0049] Furthermore, the main control circuit unit of the integrated projection display and mobile charging device can support firmware updates and software upgrades through OTA (Over-The-Air) online upgrade technology, allowing users to obtain the latest system and software at any time, ensuring the security of the system and the continuous update and expansion of functions. In addition, pre-installed applications and applications installed by users can also be kept up to date through online updates, providing users with a better user experience.

[0050] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors.
