In this embodiment, the screen projection chip is an 8269D chip. The 8269D chip can convert the video signal transmitted by the device terminal in the USB mode or the video signal transmitted by the Wifi mode (both mobile phones and computers support this function) into an HDMI signal, and output the HDMI signal to the receiving terminal. Meanwhile, 8269D can realize 90-degree rotation of the picture, the rotation can be controlled by a common IO port, the 8269D is given high and low level in a hardware mode in the example, and normal output of the picture or output after 90-degree rotation is realized.
In this embodiment, the display main control chip is an RTD2797 chip. The display main control chip RTD2797 can support the display of multiple pictures, and when the multiple pictures are displayed, the main picture can support 90-degree rotation and can receive HDMI type C signals. The RTD2797 can adjust the position, size, and scaling parameters of the sub-screen display, and can output the dot screen signal.
The working process of the method for simultaneously displaying the main picture and the sub picture in the PIP picture in the embodiment is as follows:
the display device displays the mode of the PIP after power-on. The screen projecting chip 8269D is initialized, and waits for a user to connect an external device (a mobile phone, a tablet or a notebook computer), and the screen projecting chip and the external device are in wired connection through a USB (universal serial bus) or in wireless connection through WiFi (wireless fidelity), wherein the wireless WiFi is connected in figure 1, and the USB is connected in figure 2. The RTD2797 can inform 8269D whether the current rotation state is in 8269D through 8269D rotation control pin. When the user connects the external device to 8269D, 8269D adjusts 8269D according to the obtained rotation state to output the input signal in HDMI signal form after rotating 8269D. When RTD2797 and 8269D have all obtained current rotation state, main picture can be rotated to RTD2797, and the sprite can be rotated to 8269D, and the size of sprite can be adjusted to RTD2797 simultaneously, then exports the display screen end and shows again.
As shown in fig. 4, the sub-frame is included in the main frame, and the sub-frame and the main frame rotate simultaneously or do not rotate simultaneously, and the outlines of the sub-frame and the main frame are in the same horizontal and vertical directions.

Wherein, the screen projection chip is an 8269D chip. The 8269D chip can convert the video signal transmitted by the device terminal in the USB mode or the video signal transmitted by the Wifi mode (both mobile phones and computers support this function) into an HDMI signal, and output the HDMI signal to the receiving terminal. Meanwhile, 8269D can realize 90-degree rotation of the picture, the rotation can be controlled by a common IO port, the 8269D is given high and low level in a hardware mode in the example, and normal output of the picture or output after 90-degree rotation is realized.
Wherein, the display main control chip is an RTD2797 chip. The display main control chip RTD2797 can support the display of multiple pictures, and when the multiple pictures are displayed, the main picture can support 90-degree rotation and can receive HDMI type C signals.
