In this specification, no unnecessary limitations are intended to the details of construction or design herein shown. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
As described above, as the requirements of the existing embedded devices (such as augmented reality devices, mobile phone projection, multi-screen advertisement machines, etc.) for multi-screen display become higher, a multi-screen display method is urgently needed to meet the needs of users. However, many existing system platforms have expansion limitations in applying multi-screen displays. For example, in the conventional android system, multi-screen display can be realized by three-screen display, namely, a dual-screen + WiFi mode, such as a main screen, an HDMI (High Definition Multimedia Interface) and a WiFi (wireless local area network). However, due to the limitation of hardware (e.g., the limited number of controllers for the display units), if more than three display units are required, expansion is difficult, and therefore, the present application provides a multi-screen display method to overcome the defect that the hardware of the electronic device limits the expansion of the number of display units.
The present application provides a plurality of FPGA units (Field-Programmable Gate arrays) communicatively coupled to an MCU (micro controller Unit) Unit of the electronic device, and a plurality of DSI (Display-serial Interface) units, where one end of each DSI Unit is communicatively coupled to the FPGA Unit, and the other end of each DSI Unit is communicatively coupled to a Display Unit, so that Display data can be written into the plurality of FPGA units first, and then written into the Display Unit through the plurality of DSI units, so as to expand the number of screens, thereby improving the defect that the existing multi-screen Display method is limited by hardware.
In practical applications, according to different functional requirements of electronic devices, multi-screen display methods are divided into a multi-screen co-display (e.g., augmented reality device), a multi-screen non-display (e.g., advertisement player) and a multi-screen mosaic (e.g., mobile phone projection), where the multi-screen mosaic is also a kind of multi-screen non-display, that is, contents displayed by a plurality of display units are the same, different, or spliced together to display one content.
As shown in fig. 1 to 4, a process diagram and a method block diagram of multi-screen display of the multi-screen display method are illustrated. The FPGA units are connected to the MCU unit through a system bus, and the memory space of each FPGA unit is mapped to a preset position in the memory space of the MCU unit. The plurality of FPGA units are communicatively coupled with the plurality of display units via the plurality of DSI units.
More specifically, the MCU unit may be simultaneously communicatively coupled to a plurality of said FPGA units, each of said FPGA units may be simultaneously communicatively coupled to a plurality of said DSI units, and each of said DSI units is simultaneously connected to one of said display units. In this manner, the plurality of FPGA units are modeled as memory devices for storing a predetermined range of display data (e.g., rendering data).
Each DSI unit has a preset offset address, and each display unit has a memory first address, wherein the memory first address of each display unit is obtained based on the preset offset address. It will be understood by those skilled in the art that the preset offset address corresponds to the size of the display data, i.e., the preset offset value of the memory address of each display unit should be greater than or equal to the size of the display data. Each display unit is provided with access data, wherein the access data is acquired through the MCU unit based on the resolution, the display format and the offset address of the DSI unit.
When the electronic equipment performs multi-screen different display, the MCU unit correspondingly generates a driver instruction of each display unit based on the access data of each display unit, and is used for driving each display unit respectively, wherein the MCU unit accesses the memory head address of each display unit through the DSI unit, and writes the specified display data into the memory space of the specified display unit through the FPGA unit, so that the multi-screen different display is realized.
In other words, the MCU unit accesses the access data of each display unit through the DSI unit to write the designated display data into the memory space of the designated display unit. Firstly, the display data is written into the memory space of the designated FPGA through the MCU unit, at this time, the designated FPGA unit is in communication connection with the designated display unit through the DSI unit, and finally, the designated display data is written into the memory space of the designated display unit through the FPGA unit. Through the mode, appointed the display element just can show appointed demonstration data to reach many screens different effect that shows, perhaps a plurality of the display element shows the different parts of a demonstration data simultaneously, thereby reaches the effect that many screens were spliced, and then satisfies the demand that present electronic equipment (like advertisement machine, cell-phone projection etc.) show to many screens different.
Accordingly, as shown in fig. 1, the multi-screen displaying method 100 includes the steps of:
s101: acquiring preset offset addresses of a plurality of DSI units;
s102: respectively acquiring memory initial addresses of a plurality of display units connected with the plurality of DSI units based on preset offset addresses of the plurality of DSIs, wherein each display unit has a display parameter, and the display parameters comprise the resolution and the display format of the display unit;

s104: correspondingly generating a driver program instruction of each display unit based on the access parameter of each display unit so as to drive each display unit;
s105: writing specified display data into an FPGA unit connected to the specified display unit by accessing the specified memory head address of the display unit, wherein the memory space of the FPGA unit is mapped to the specified address of the memory space of the MCU unit;
s106: and writing the appointed display data into the appointed memory space of the display unit.
In one possible implementation manner of this embodiment, as shown in fig. 2A, step S105: writing a designated display data into an FPGA unit coupled to the designated display unit by accessing a memory head address of the designated display unit, wherein a memory space of the FPGA unit is mapped in the designated address of the memory space of the MCU unit, further comprising:
s1051: establishing a sequence table based on the display parameters and the memory head addresses of each display unit and preset offset addresses of the DSI units, wherein the sequence table has a plurality of access sequence numbers, and the access sequence numbers respectively correspond to the memory head addresses of the display units;
s1052: scaling and format converting the specified display data based on the specified display parameters of the display unit;
s1053: and writing the specified display data into the FPGA unit connected with the specified display unit through the access sequence number of the display unit specified in the sequence list.
Those skilled in the art will appreciate that the number of the FPGA unit, the DSI unit, and the display unit shown in fig. 4 may be increased or decreased according to the requirement of the electronic device, and is not limited to the number shown in the drawing. The manner of obtaining the sequence table (e.g., through a hardware abstraction layer) has been developed and matured in the communication field based on the resolution, the display format, the DSI offset position, and the memory first address of each display unit, which is not described again in this application. The display unit may be implemented as a liquid crystal display, a projector, etc., and may be implemented as any display device that receives the display data and presents the display data to a user, which is not limited herein.
It is worth mentioning that the multi-screen display method 100 proposed in the present application simulates the FPGA unit as a memory device to connect with the multiple display units, so that not only can the limitation of hardware devices on the expansion of the multiple display units of the electronic device be broken through, but also the specified display data can be more flexibly written into the specified display units, thereby achieving the effects of multi-screen different display and multi-screen splicing of the electronic device.
As shown in fig. 2B, after the DSI unit accesses the memory head address of the designated display unit, writes the display data designated in the MCU unit into the FPGA connected to the designated display unit, and writes the designated display data into the memory space of the designated display unit, the designated display data is processed first and then written into the other FPGA units, so that the same display data is copied into the memory spaces of the other display units through the FPGA unit and the DSI unit, and the designated display data satisfies the resolution and display format of each written display unit.
More specifically, after display data is written into the FPGA cell connected to the designated display cell, the display data is first scaled and format-converted based on the resolution and display format of the designated display cell, so that the written display data meets the resolution and display format of the designated display cell, thereby achieving the effect of multi-screen simultaneous display.
According to another preferred embodiment of the present application, as shown in fig. 2B, the step S105: writing a designated display data into an FPGA unit coupled to the designated display unit by accessing a memory head address of the designated display unit, wherein a memory space of the FPGA unit is mapped in the designated address of the memory space of the MCU unit, further comprising:

S1052A: writing the display data into a memory space of a first display unit based on an access parameter of the first display unit;
S1053A: processing the designated display data based on the display parameters of the first display unit and a second display unit, and writing the processed display data into the FPGA unit connected with the second display unit;
S1054A: and writing the processed display data into the second display unit based on the access parameter of the second display unit.
Preferably, in this way, the same display data can be copied and processed in the MCU unit to be written into the plurality of display screens through the FPGA unit, thereby achieving the effect of displaying different display screens simultaneously. Furthermore, by applying the multi-screen display method of the electronic equipment, for the electronic equipment, not only the limitation of hardware can be broken through to achieve the purpose of expanding multi-screen display, but also other properties of the electronic equipment can be optimized. For example, by replacing hardware with an FPGA unit, the overall size of the electronic device may be reduced, thereby improving convenience for use (e.g., an augmented reality device is more convenient to wear), and reducing manufacturing cost of the electronic device, which are beneficial effects generated by applying the multi-screen display method 100.
