Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
The embodiment of the application provides a display driving method, a device and a system.
As shown in fig. 1, fig. 1 is a schematic flow chart of a display driving method according to an embodiment of the present application, where the display driving method is applied to a display driving device, and the display driving device includes a mobile industry processor interface module and a serial peripheral interface module, and the specific flow may be as follows:
s101, the mobile industry processor interface module receives initial display data sent by a user space.
The mobile industry processor interface module is used for executing related operations for driving the MIPI display screen, the user space is one of blocks of virtual memory in the operating system, and the initial display data comprises display data stored in the user space.
Specifically, the virtual memory of the operating system is divided into two blocks, one block is a kernel space, the other block is a user space, in the practical application process, related instructions are often generated based on user operation and stored in the user space, and in order to execute the related instructions, communication between the user space and the kernel space and/or hardware devices is required, and it is required to be noted that the user space cannot directly access the kernel space and/or the hardware devices, and generally needs to communicate with the kernel space and/or the hardware devices in a system call manner.
In this embodiment, as shown in fig. 2a or fig. 2b, in the MIPI display framework of the MT6739 processor, the mobile industry processor interface module 221 and the serial peripheral interface module 222 are both located in the kernel space 22, and the initial display data (e.g., video data) stored in the user space 21 is sent to the mobile industry processor interface module 221 located in the kernel space 22 by way of a system call.
S102, the mobile industry processor interface module sends the initial display data to the serial peripheral interface module.
The serial peripheral interface module is used for executing related operation of driving the SPI display screen. Specifically, in the prior art, due to the limitation of frame logic, the current MIPI display frame can only drive the MIPI display screen, but cannot drive the SPI display screen, and if the SPI display screen needs to be driven, the SPI display frame needs to be designed and developed separately, so that the development cost of the display frame is high.
In this embodiment, as shown in fig. 2a or fig. 2b, the serial peripheral interface module 222 is added in the MIPI display frame, and the serial peripheral interface module 222 is connected with the mobile industry processor interface module 221, so that display data is transmitted to the serial peripheral interface module 222 through the mobile industry processor interface module 221 to drive the SPI display screen, that is, the SPI display screen can be driven in the MIPI display frame without separately developing the SPI display frame, thereby reducing the development cost of the display frame.
Specifically, since the user space is different from the data format supported (i.e., readable) by the kernel space, in order for the kernel space to correctly read the received data, the data format of the received data needs to be converted (converted into the data format readable by the kernel space), in one embodiment, as shown in fig. 2a, a first data conversion chip 2211 and a frame node information transmission chip 2212 are disposed in the mobile industry processor interface module 221, and are used to send the initial display data in the user space 21 to the first data conversion chip 2211 through a system call, and then the first data conversion chip 2211 converts the data format of the initial display data into the readable data format of the kernel space and sends the initial display data in the readable data format of the kernel space to the frame node information transmission chip 2212, so that the initial display data in the readable data format of the kernel space is sent through the frame node information transmission chip 2212, and the frame node information is sent to the mobile industry processor interface driving chip 2213 in the mobile industry processor interface module 221, and the second data conversion chip 2221 in the peripheral interface module 222.
Further, in another embodiment, if the user space is in the power-off charging state, as shown in fig. 2b, after the initial display data (for example, the picture data of the charging screen) in the user space 21 is sent to the first data conversion chip 2211 through the system call, the first data conversion chip 2211 converts the data format of the initial display data into the kernel space readable data format, and sends the initial display data with the data format of the kernel space readable data format to the second data conversion chip 2221 in the serial peripheral interface module 222.
S103, the serial peripheral interface module converts the initial display data into target display data.
Wherein the target display data is display data supported (readable) by the serial peripheral interface module. Specifically, since the mobile industry processor interface module is different from the data format supported (i.e., readable) by the serial peripheral interface module, in order for the serial peripheral interface module to correctly read the received data, the data format of the received data needs to be converted (to a data format readable by the serial peripheral interface module).
In this embodiment, as shown in fig. 2a or fig. 2b, the second data conversion chip 2221 performs format conversion on initial display data (for example, video data or picture data of a charging screen) with a data format that is in a kernel space readable data format, so as to obtain initial display data with a data format that is in a serial peripheral interface readable data format, and uses the initial display data with the data format that is in the serial peripheral interface readable data format as target display data.
S104, the serial peripheral interface module drives the serial peripheral interface display screen to display target display data, wherein the serial peripheral interface display screen comprises a display screen connected with the serial peripheral interface module.
In this embodiment, the serial peripheral interface module is further provided with a serial peripheral interface driving chip, and the serial peripheral interface driving chip is configured to provide driving conditions for the serial peripheral interface display screen to drive the serial peripheral interface display screen to work, specifically, as shown in fig. 2a, the mobile industry processor interface driving chip 2213 sends initial display data in a data format that is in a kernel space readable data format to the mobile industry processor interface virtual display screen 231 (no display screen), and at the same time, the second data conversion chip 2221 sends target display data to the serial peripheral interface driving chip 2222, so that the serial peripheral interface driving chip 2222 drives the serial peripheral interface display screen 232 (i.e. the display screen connected to the serial peripheral interface driving chip 2222) to display the target display data.
In another embodiment, since the MIPI interface display screen cannot normally work in a state where the user space is in a shutdown charging state (i.e. a shutdown charging screen cannot be displayed), as shown in fig. 2b, the second data conversion chip 2221 sends the target display data to the serial peripheral interface driver chip 2222, so that the serial peripheral interface driver chip 2222 drives the serial peripheral interface display screen 232 to display the target display data, where the serial peripheral interface display screen 232 includes a display screen connected to the serial peripheral interface driver chip 2222.
As can be seen from the foregoing, the display driving method provided by the present application is applied to a display driving device, where the display driving device includes a mobile industry processor interface module and a serial peripheral interface module, first receives initial display data sent by a user space through the mobile industry processor interface module, and sends the initial display data to the serial peripheral interface module, then the serial peripheral interface module converts the initial display data into target display data, and drives a serial peripheral interface display screen to display the target display data, where the serial peripheral interface display screen includes a display screen connected to the serial peripheral interface module. Because the mobile industry processor interface module can send the initial display data to the serial peripheral interface module, the serial peripheral interface module can drive the serial peripheral interface display screen according to the initial display data, that is to say, the SPI display screen can be driven in the MIPI display frame without independently developing the SPI display frame, thereby reducing the development cost of the display frame and further relieving the technical problem of high development cost of the current display frame.

The audio circuit 660 may transmit the received electrical signal converted from audio data to the speaker 661, and the electrical signal is converted into a sound signal by the speaker 661 to be output; on the other hand, microphone 662 converts the collected sound signals into electrical signals, which are received by audio circuit 660 and converted into audio data, which are processed by audio data output processor 680 for transmission to, for example, another terminal via RF circuit 610, or which are output to memory 620 for further processing. Audio circuitry 660 may also include an ear bud jack to provide communication of the peripheral headphones with electronic device 600.
The electronic device 600 may facilitate user email, web browsing, streaming media access, etc. via the transmission module 670 (e.g., wi-Fi module), which provides wireless broadband internet access to the user. Although fig. 6 shows the transmission module 670, it is understood that it does not belong to the essential constitution of the electronic device 600, and can be omitted entirely as required within the scope not changing the essence of the application.
