Generally, there are two data transmission modes for the mobile control center and the screen: video mode and command mode.
Video Mode (Video Mode): this mode of operation is similar to the conventional RGB interface, and the host needs to continuously refresh the data of the display, even if it is a still image, and needs to refresh the display data in real time at a certain frame rate. Since the synchronization information is transmitted without using a dedicated data signal, the control signal and the RGB data are transmitted in the form of a message through the bus. Because the host needs to refresh the display information periodically, the display does not need a frame buffer, i.e. GRAM (Graphic Random-Access Memory), inside the display.
Command mode (Command mode): the bus controller uses the display command messages to send a stream of pixel data to the display. The display has a frame buffer (i.e. GRAM, image Random-Access Memory) as large as the number of pixels displayed on the screen to store all the pixel data, i.e. to initiate the display technology of panel auto-refresh. Once the data is placed in the GRAM of the display, the timing controller takes the data from the GRAM and automatically displays them on the screen. LCM supports COMMAND mode, which enables MIPI bus controller of control center (MCU) without periodically refreshing the display.

step S601, when the main display is displaying data and a trigger display event is monitored, controlling the auxiliary display to display dynamic information, and closing the main display or controlling the main display to display static information.
Generally, there are two data transmission modes for the mobile control center and the screen: video mode and command mode.
Video Mode (Video Mode): this mode of operation is similar to the conventional RGB interface, and the host needs to continuously refresh the data of the display, even if it is a still image, and needs to refresh the display data in real time at a certain frame rate. Since the synchronization information is transmitted without using a dedicated data signal, the control signal and the RGB data are transmitted in the form of a message through the bus. Because the host needs to refresh the display information periodically, the display does not need a frame buffer, i.e. GRAM (Graphic Random-Access Memory), inside the display.
Command mode (Command mode): the bus controller uses the display command messages to send a stream of pixel data to the display. The display has a frame buffer (i.e. GRAM, image Random-Access Memory) as large as the number of pixels displayed on the screen to store all the pixel data, i.e. to initiate the display technology of panel auto-refresh. Once the data is placed in the GRAM of the display, the timing controller takes the data from the GRAM and automatically displays them on the screen. LCM supports COMMAND mode, which enables MIPI bus controller of control center (MCU) without periodically refreshing the display. Specifically, the method comprises the following steps: when the screen displays a static picture, the content of the picture is not changed, and then the central control unit (application processor) GPU of the mobile device stops working and only needs to output the data in the GRAM in the LCM to the screen at regular time. In this embodiment, the processing unit 203b performs data transmission with the first display 201b and the second display 202b through a command mode.
By default, the processing unit 203b controls the main display to display data information and closes the auxiliary display, i.e. the first connection terminal of the switching unit 204b is electrically connected to the control terminal to connect the main display to the processing unit 203 b. So as to achieve the effect of energy saving and electricity saving. When the main display screen is displaying data and the processing unit 203b monitors a triggering display event, the switching unit 204b electrically connects the second connection terminal to the control terminal, i.e. the switching unit 204b disconnects the processor from the main display screen and electrically connects the auxiliary display screen to the processing unit 203b, and the processing unit 203b controls the auxiliary display screen to display dynamic information, close the main display screen or control the main display screen to display static information (i.e. the main screen is in a self-refresh mode).
Step S602, monitoring whether the auxiliary display screen completes displaying.
Step S603, when the auxiliary display finishes displaying, controlling the main display to display dynamic information, and closing the auxiliary display or controlling the auxiliary display to display static information.
Specifically, when the auxiliary display completes displaying, the second connection terminal is electrically connected to the control terminal, i.e., the auxiliary display is disconnected from the processing unit 203b, and the main display is electrically connected to the processing unit 203 b. The processing unit 203b controls the main display to display dynamic information, closes the auxiliary display or controls the auxiliary display to display static information (i.e. the auxiliary screen is in self-refresh mode).
The following is a specific example, it should be understood that the example is only for better explanation of the present invention and is not meant as a limitation of the present invention.
Still taking the micro letter code scanning payment as an example, when the user switches the micro letter payment code to the auxiliary display screen for display, the processing unit 203b monitors whether the payment is completed, and when the payment operation is completed, the switching unit 204b electrically connects the second connection terminal to the control terminal, i.e., disconnects the auxiliary display screen from the processing unit 203b, and electrically connects the main display screen to the processing unit 203 b. The processing unit 203b controls the main display to display dynamic information, and closes the auxiliary display or controls the auxiliary display to display static information.
