Description

Technical Field

[0001] The present invention relates to the field of screen projection display, and more particularly to a portable mobile phone screen display. Background Art

[0002] Smartphones, the culmination of industrial production and scientific technology, have become indispensable tools for human life, work, and learning. Beyond basic communication, they are also widely used for live streaming, filming, watching movies, gaming, online shopping, taking online classes, and navigation. However, smartphones designed for multiple uses are inherently difficult to accommodate the specific needs of each application. For example, when watching movies on a smartphone, a screen size designed for portability is insufficient for large-screen viewing. When live streaming or taking selfies on a smartphone, a screen and camera layout designed for the visual aesthetic of a large screen-to-body ratio makes it impossible to simultaneously use the relatively high-performance rear camera to monitor the footage while still looking directly at the screen.

[0003] In view of this, a large number of smartphone peripheral hardware and interconnected software have been developed to meet the specific needs of different uses. For example, based on the demand for large-screen viewing, the current smartphone system itself and viewing software are usually developed with a screen projection function. A common usage scenario is to use the screen projection function of the smartphone viewing software to project the interface of the viewing software to the TV, so as to achieve large-screen viewing without affecting the use of the smartphone. For another example, when using a smartphone for live broadcasts or selfies, you can choose a suitable webcam from the aforementioned peripheral hardware, so that you can face the phone screen to monitor the shooting picture while ensuring the quality of the shooting. However, for outdoor viewing needs, such as children's viewing needs during travel, the phone can only be given to children, which can easily make the phone out of the control of the parents. This not only poses the risk of misoperation, but also may expose children to inappropriate information and affect the parents' normal use of the phone for work or social needs. In addition, for the needs of using mobile phones for live streaming or selfies, webcams have limited functions, and the cost of webcams with performance comparable to that of smartphone rear cameras is also relatively high. Since smartphone rear cameras themselves are of higher quality, using a webcam to replace a smartphone's rear camera simply to monitor the images captured by the smartphone is not a wise solution.

[0042] Specifically, with reference to FIG1 of the accompanying drawings of the specification of the present invention, a structural block diagram of the portable mobile phone same-screen display of the present invention is illustrated, wherein the portable mobile phone same-screen display includes a processor module 10, a display screen 20 communicatively connected to the processor module 10, a WIFI module 30, and a Bluetooth module 40, wherein the portable mobile phone same-screen display is configured to receive the audio and video projection signal from the mobile phone end only by the WIFI module 30, and to transmit the control instruction generated by the processor module 10 for the mobile phone end back to the mobile phone end only by the Bluetooth module 40, correspondingly, the WIFI module 30 receives the audio and video projection signal from the mobile phone end and transmits the audio and video projection signal to the processor module 10, and the processor module 10 controls the display screen 20 to display on the same screen according to the received audio and video projection signal, so as to ensure the independence of the transmission path of the audio and video projection signal and the control instruction, which is conducive to ensuring the transmission stability and transmission efficiency of the audio and video projection signal and the control instruction, thereby ensuring the image quality of the same-screen display of the portable mobile phone same-screen display and reducing the delay of the same-screen display of the portable mobile phone same-screen display.

[0043] It can be understood that when the portable mobile phone same-screen display is set to only use the WIFI module 30 to receive the audio and video projection signal from the mobile phone, the transmission path of the audio and video projection signal is stable and single, and it is conducive to simplifying the adaptability program design of the portable mobile phone same-screen display to the projection protocol of different mobile phone systems.

[0044] Preferably, when the portable mobile phone same-screen display is set to only use the WIFI module 30 to receive the audio and video projection signal from the mobile phone, in order to further ensure the image quality of the portable mobile phone same-screen display and reduce the delay of the portable mobile phone same-screen display, the WIFI module 30 is set to select a WIFI module that supports WIFI 7.

[0045] Furthermore, the portable mobile phone same-screen display also includes an audio output module 50 communicatively connected to the processor module 10, wherein the processor module 10 controls the audio output of the audio output module 50 according to the received audio and video projection signal, so that the portable mobile phone same-screen display is set to a state where only the WIFI module 30 receives the audio and video projection signal from the mobile phone end, so that the image displayed on the display screen 20 can be synchronized with the audio output of the audio output module 50.

[0046] It is understandable that the audio and video projection signal formed based on the projection protocol of the mobile phone system usually includes audio information synchronously. Therefore, when the processor module 10 is configured to control the audio output of the audio output module 50 according to the received audio and video projection signal, it is possible to avoid receiving separate audio information with the Bluetooth module 40, thereby avoiding the transmission of repetitive information and maintaining the synchronization of the image displayed on the display screen 20 and the audio output of the audio output module 50.

[0047] Furthermore, the portable mobile phone same-screen display also includes at least one button 60, wherein the portable mobile phone same-screen display is configured to allow the processor module 10 to generate the control instruction based on the corresponding touch operation of the display screen 20 and / or the pressing operation of the corresponding button 60, so that the portable mobile phone same-screen display is further integrated with the functions of the Bluetooth touch panel and / or Bluetooth control button and can take into account the specific needs of the mobile phone in multiple uses such as watching movies, live broadcasting, shooting and online classes, and the portable mobile phone same-screen display is configured to only use the Bluetooth module 40 to transmit the control instructions generated by the processor module 10 back to the mobile phone end, which is conducive to simplifying the adaptability program design of the portable mobile phone same-screen display to the Bluetooth control protocol of different mobile phone systems.

[0048] For example, the portable mobile phone same-screen display is configured to allow the processor module 10 to generate the control instruction for controlling the mobile phone shutter based on the pressing operation of at least one of the buttons 60, so that the portable mobile phone same-screen display is integrated with the function of the Bluetooth shutter button and can take into account the remote control shutter requirements of the mobile phone for shooting purposes.

[0049] It is understandable that the Bluetooth control protocols of different mobile phone systems usually include a shutter control interface. Therefore, when the portable mobile phone same-screen display is set to only use the Bluetooth module 40 to transmit the control instructions generated by the processor module 10 back to the mobile phone end, it is beneficial to simplify the adaptability program design of the portable mobile phone same-screen display to the Bluetooth control protocols of different mobile phone systems.

[0050] Furthermore, the portable mobile phone with the same-screen display also includes a sound pickup module 70 communicatively connected to the processor module 10, wherein the processor module 10 is configured to allow the control instruction to be generated based on the recognition of the sound signal picked up by the sound pickup module 70, thereby forming voice control of the mobile phone end. Therefore, it can be used in scenarios where the mobile phone end is relatively far away from the user, such as long-distance selfie or live broadcast scenarios, compared with directly performing voice control on the mobile phone end, the sensitivity and stability of the voice control on the mobile phone end can be guaranteed and the voice control delay can be reduced.

[0051] In particular, the processor module 10 is further configured to allow the Bluetooth module 40 to transmit the sound signal picked up by the sound pickup module 70 back to the mobile phone end, so that the portable mobile phone same-screen display is further integrated with the function of a Bluetooth pickup and can take into account the sound pickup needs of the mobile phone for multiple purposes such as live broadcast, shooting and online classes, and is conducive to simplifying the adaptability program design of the portable mobile phone same-screen display to the Bluetooth accessory protocol that comes with different mobile phone systems.

[0052] That is to say, since the portable mobile phone same-screen display is configured to receive the video and audio projection signal from the mobile phone only by the WIFI module 30, and to transmit the control instructions generated by the processor module 10 back to the mobile phone only by the Bluetooth module 40, and to allow the sound signal picked up by the sound pickup module 70 to be transmitted back to the mobile phone by the Bluetooth module 40, during the communication process between the portable mobile phone same-screen display and the mobile phone of the present invention, the downlink communication channel of the portable mobile phone same-screen display is mainly provided by the WIFI module 30, and the uplink communication channel of the portable mobile phone same-screen display is mainly provided by the Bluetooth module 40. This is conducive to ensuring the relative independence of the uplink communication channel and the downlink communication channel of the portable mobile phone same-screen display, and correspondingly ensuring the stability and transmission efficiency of the uplink communication channel and the downlink communication channel of the portable mobile phone same-screen display, thereby ensuring the image quality of the same-screen display of the portable mobile phone same-screen display and reducing the delay of the same-screen display of the portable mobile phone same-screen display.
