As mentioned in the background technology, when the terminal starts up, if the GPU and/or the window manager are not started, if it is still necessary to perform multi-screen display (such as multiple screens displaying the terminal's boot logo (logo), etc.), then There will be exceptions.

In order to solve the above problems, an embodiment of the present invention provides a method for displaying multiple screens, including: obtaining a multi-screen display picture from the first partition, the multi-screen display picture includes several target image units, and the The target image unit is in one-to-one correspondence with the screens; several target image units are segmented from the multi-screen display picture; and each target image unit obtained by segmenting is displayed on a corresponding screen. Thus, multiple screens can be displayed synchronously even when the GPU and/or the window manager of the terminal are not activated.

In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for displaying multiple screens according to an embodiment of the present invention. The method for displaying multiple screens may be performed by a SOC or by a terminal including a SOC. Further, the method It is executed by a central processing unit (Central Processing Unit, referred to as CPU) in the SOC or a controller with similar functions to the CPU. The following uses the SOC to execute the method as an example for illustration. The SOC may be coupled to multiple screens, for example, may be coupled to multiple screens through a field-programmable gate array (Field-Programmable Gate Array, FPGA for short) (wherein, the FPGA may be a cross-linked FPGA). Among them, the SOC can communicate with each screen through the Mobile Industry Processor Interface (MIPI) Display Serial Interface (DSI) protocol to control the display screens on each screen. Wherein, the terminal can be a computer, a smart phone, a server (such as a cloud server), etc., and the terminal can be applied to a financial cash register or a car.

In a specific embodiment, the method is executed by an SOC, and the SOC is connected to the plurality of screens through an FPGA. Please refer to Fig. 2, Fig. 2 is the connection diagram of a kind of SOC and screen of the embodiment of the present invention; SOC 201 connects and couples n screens through FPGA 202 (the n screens include screen 2031, screen 2032, ..., screen 203n) , n is a positive integer. The SOC 201 is connected to the FPGA 202 through a plurality of interfaces, and the plurality of interfaces may include a general-purpose I/O interface (represented by GIPO in the figure), a serial peripheral interface (Serial Peripheral Interface, referred to as SPI), MIPI-DSI, One or more of the serial transfer bus (I2C) interfaces. Among them, the general-purpose I/O interface can be used to transmit reset (reset) signals, the I2C interface can be used to configure the registers of the FPGA 202, and the SPI interface can be used for the FPGA 202 to download firmware, so as to realize the support of the SOC 201 for multi-screen display. The FPGA 202 communicates with each of the n screens through the MIPI-DSI interface, thus, the SOC 201 expands one MIPI-DSI interface into multiple MIPI-DSI interfaces through the FPGA 202, and the SOC 201 can also pass the physical layer (Physical , referred to as PHY) interface communicates with each of the n screens. In FIG. 2 , the direction of the data transmission on each interface is indicated by the direction of the arrow.

In another specific embodiment, the method is performed by a SOC, and the SOC is connected to the plurality of screens. Compared with the connection described in FIG. 2 , multiple screens and connection interfaces with multiple screens (such as MIPI-DSI interfaces) can be integrated inside the SOC 201, so that the SOC 201 can be directly connected with multiple screens without using the FPGA 202 Connect with multiple screens.

The GPU can usually be integrated inside the SOC, or externally coupled to the SOC. After the GPU is started normally, the GPU will perform processing such as scaling down the display content of multiple screens (including the main screen and the secondary screen), and will multiple screens The respective display content is spliced into one picture, and the GPU sends the spliced picture to the FPGA, and the FPGA divides the received picture to obtain the display content of each screen, and performs processing such as scaling up each divided display content And display the processed display content on each screen respectively. Yet inventor finds through research, in traditional multi-screen display, multi-screen displays simultaneously must GPU and window manager (such as Android (Android) system Window Manager etc.) all start up, just can finish above-mentioned display process. However, when the GPU and the window manager are not fully started, for example, the time when the terminal displays the boot image is during the boot loader (uboot) stage of the embedded system. The display of each screen cannot be controlled by the GPU and the terminal system.

In order to solve the above problems, the embodiment of the present invention adopts a method for displaying multiple screens including the following steps S101 to S103. The method is applied to a scenario where the GPU and/or the window manager have not all been started. The details are as follows:

Step S101, obtaining a multi-screen display picture from the first partition, the multi-screen display picture includes several target image units, and the target image units correspond to the screens one by one;

Step S102, segmenting several target image units from the multi-screen display picture;

Step S103, displaying each segmented target image unit on a corresponding screen.

Wherein, the first partition is used to store pictures displayed on multiple screens (such as multi-screen startup LOGO). Partition is to divide the read-only memory (Read-Only Memory, ROM) of SOC into multiple blocks, each partition stores read-only files (such as bin files) or resources of different terminal operating systems, and can be divided according to different stored files It is the boot partition (uboot partition), the partition of the operating system (also known as the system partition), the user data partition, and so on.

The pictures for displaying on multiple screens are stored in the first partition, and the pictures for displaying on multiple screens include target image units for displaying on each screen. Optionally, multiple target image units are spliced into the same picture to generate a multi-screen display picture, and the number of target image units in the multi-screen display picture is consistent with the number of screens connected to the SOC.

The target image unit is a preset picture, and the preset picture may be a landscape or a brand LOGO. Correspondingly, the multi-screen display picture includes the same or different multiple landscape paintings, or the multi-screen display picture includes the same or different multiple brand LOGOs. It should be noted that the target image unit includes but is not limited to the foregoing examples, and the target image unit can be designed according to the requirements of the content to be displayed on each screen.

Optionally, the size of each target image unit stitched in the multi-screen display picture may be the same or different. Further, if the size of each target image unit in the multi-screen display picture is the same, but the sizes of the display areas on different screens are different, after the SOC divides the target image unit to be displayed on different screens from the multi-screen display picture, and then according to Depending on the display size of the screen, processing such as enlarging or reducing the segmented target image unit is performed, and then the processed target image unit is displayed on the corresponding screen.

Optionally, the step S102, segmenting several target image units from the multi-screen display picture includes: segmenting several target image units from the multi-screen display picture according to preset segmentation rules unit. The preset segmentation rules are designed according to the number of screens connected to the SOC. For example, it can be determined that each screen corresponds to the area in the multi-screen display picture, and each area contains the target image unit, thereby dividing the multi-screen display area according to each screen. The region is divided to obtain the target image unit to be displayed on each screen. Further, the sizes of the areas of the multi-screen display pictures corresponding to each screen in the multi-screen display pictures are the same, and the multi-screen display pictures can be divided into several areas of the same size according to the number of screens. For example, if there are 4 screens, you can Divide the multi-screen display picture into four areas: upper left, lower left, upper right, and lower right, each area is an image to be displayed on one of the screens, and each area includes a target image unit.

Through the display method of multiple screens in Figure 1, if the GPU and the window manager have not all started (such as the uboot stage), the SOC or the terminal can obtain the multi-screen display pictures stored in the first partition from the first partition, And segment the obtained multi-screen display picture to obtain multiple target image units (such as the boot LOGO of the terminal), and send each target image unit to the corresponding display screen, so that each screen displays the received target image unit. Therefore, even if the GPU and the window manager are not all started, the multiple screens coupled to the SOC can be displayed normally.

In one embodiment, the size of the several target image units is the same, after the step S102 in FIG. 1 divides the several target image units from the multi-screen display picture, it may also include: Each target image unit of is processed according to the size of its corresponding screen to obtain the target image unit for display, wherein the processing includes one or more of enlargement, reduction, and row-column conversion; step S103 Displaying each segmented target image unit on a corresponding screen may include: displaying the target image unit used for display on a corresponding screen.

Optionally, the size of each target image unit in the multi-screen display pictures stored in the first partition is the same, and when the area sizes of the target image units displayed on multiple screens are also the same, the same zoom-in and zoom-out can be performed on each target image unit or row-column conversion, etc., so as to achieve the same display effect on each screen.

Optionally, the size of each target image unit in the multi-screen display pictures stored in the first partition is the same. The target image unit performs different processing such as zooming in, zooming out, or row and column conversion, so as to realize the display results of each screen.
