Detailed Description
As known in the background art, when a terminal is powered on and started, if a GPU and/or a window manager is not started, and multi-screen display is still required (for example, multiple screens all display a power-on flag (logo) of the terminal), an exception may exist.
To solve the above problem, an embodiment of the present invention provides a method for displaying multiple screens, including: acquiring a multi-screen display picture from a first partition, wherein the multi-screen display picture comprises a plurality of target image units, and the target image units correspond to screens one by one; segmenting a plurality of target image units from the multi-screen display picture; and displaying each target image unit obtained by segmentation on a corresponding screen. Thus, even when the GPU of the terminal and/or the window manager are not started, the plurality of screens can be displayed in synchronization.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for displaying a plurality of screens according to an embodiment of the present invention, where the method for displaying a plurality of screens may be executed by an SOC or a terminal including the SOC, and further, the method is executed by a Central Processing Unit (CPU) in the SOC or a controller having a function similar to that of the CPU, and the execution of the method by the SOC is described as an example below. The SOC may be coupled to the plurality of screens, for example, by a Field-Programmable Gate Array (FPGA), which may be a cross-coupled (cross-coupled) FPGA. The SOC may communicate with each screen through a Mobile Industry Processor Interface (MIPI) Display Serial Interface (DSI) protocol to control a Display screen on each screen. The terminal may be a computer, a smart phone, a server (such as a cloud server), and the like, and the terminal may be applied to a financial cash register or an automobile.
In one embodiment, the method is performed by an SOC, which is coupled to the plurality of screens via an FPGA. Referring to fig. 2, fig. 2 is a connection diagram of an SOC and a screen according to an embodiment of the invention; the SOC 201 is coupled to n screens (the n screens include screen 2031, screen 2032, …, and screen 203n) through the FPGA202, where n is a positive integer. The SOC 201 is connected to the FPGA202 through a plurality of interfaces, which may include one or more of a general purpose I/O Interface (GIPO in the figure), a Serial Peripheral Interface (SPI), a MIPI-DSI, and a Serial transmission bus (I2C) Interface. The general I/O interface may be configured to transmit a reset (reset) signal, the I2C interface may be configured to configure a register of the FPGA202, and the SPI interface may be used by the FPGA202 to download firmware, so as to support the multi-screen display by the SOC 201. The FPGA202 communicates with each screen of the n screens through a MIPI-DSI interface, therefore, the SOC 201 expands one MIPI-DSI interface into multiple MIPI-DSI interfaces through the FPGA202, and the SOC 201 can also communicate with each screen of the n screens through a Physical layer (PHY) interface. The direction of data transmission over the respective interfaces is indicated in fig. 2 by the direction of arrows.
In another embodiment, the method is performed by an SOC, the SOC coupled to the plurality of screens. Compared with the connection described in fig. 2, multiple screens and connection interfaces (such as MIPI-DSI interfaces) with the multiple screens can be integrated inside the SOC 201, so that the SOC 201 and the multiple screens can be directly connected without being connected with the multiple screens through the FPGA 202.
The GPU may be generally integrated within the SOC, or externally coupled to the SOC, and after the GPU is normally started, the GPU may perform processing such as scaling down on display contents of a plurality of screens (including a main screen and a sub screen), and concatenate the display contents of the plurality of screens into one picture, the GPU transmits the concatenated picture to the FPGA, the FPGA divides the received picture into display contents of each screen, and performs processing such as enlarging (scale up) on each divided display content, and displays the processed display contents on each screen. However, the inventor of the present invention has found that, in the conventional multi-screen display, the multi-screen simultaneous display must start both the GPU and the Window Manager (e.g., Window Manager of Android system, etc.) to complete the above display process. However, when the GPU and the window manager are not completely started, for example, the terminal displays the boot image at a boot loader (i.e., uboot) stage of the embedded system, the GPU and the android system of the terminal are not started at this time, and the multiple screens cannot control the display of each screen through the GPU and the terminal system.
In order to solve the above problem, the embodiment of the present invention employs a method for displaying multiple screens, which includes the following steps S101 to S103, and is applied to a scenario in which the GPU and/or the window manager are not completely started, and the following is detailed below:
step S101, a multi-screen display picture is obtained from a first partition, the multi-screen display picture comprises a plurality of target image units, and the target image units correspond to screens one by one;
step S102, a plurality of target image units are divided from the multi-screen display picture;
step S103, displaying each target image unit obtained by dividing on a corresponding screen.
The first partition is used for storing multi-screen display pictures (such as a multi-screen boot LOGO). The partition is a partition that divides a Read-Only Memory (ROM) of the SOC into a plurality of blocks, each partition stores Read-Only files (e.g., bin files) or resources of different terminal operating systems, and may be divided into a boot partition, an operating system partition (also referred to as a system partition), a user data partition, and the like according to the stored files.
And storing pictures for a plurality of screen displays in the first partition, wherein the multi-screen display pictures contain target image units for displaying of the screens. Optionally, a plurality of target image units are spliced in the same picture to generate a multi-screen display picture, and the number of the target image units in the multi-screen display picture is consistent with the number of the screens connected to the SOC.
The target image unit is a preset picture, and the preset picture can be a landscape painting or a brand LOGO and the like. Correspondingly, the multi-screen display picture comprises a plurality of same or different scenic pictures, or the multi-screen display picture comprises a plurality of same or different brands LOGO. It should be noted that the target image unit includes, but is not limited to, the foregoing examples, and the target image unit may be designed according to the requirements of the content to be displayed on each screen.
Optionally, the sizes of the target image units spliced in the multi-screen display picture may be the same or different. Further, if the sizes of the target image units in the multi-screen display picture are the same, but the sizes of the display areas on different screens are different, the SOC divides the target image units to be displayed on different screens from the multi-screen display picture, then performs processing such as enlarging or reducing on the divided target image units according to the display sizes of the different screens, and then displays the processed target image units on the corresponding screens.
Optionally, in step S102, segmenting a plurality of target image units from the multi-screen display picture, including: and according to a preset segmentation rule, segmenting a plurality of target image units from the multi-screen display picture. The preset segmentation rule is designed according to the number of the screens connected to the SOC, for example, a region in the multi-screen image corresponding to each screen may be determined, and each region includes a target image unit, so that the multi-screen display region is divided according to the region corresponding to each screen, and the target image unit to be displayed by each screen is obtained. Further, the regions of the multi-screen display picture corresponding to the respective screens in the multi-screen display picture have the same size, and the multi-screen display picture can be divided into a plurality of regions having the same size according to the number of the screens, for example, if there are 4 screens, the multi-screen display picture can be divided into four regions, i.e., an upper left region, a lower left region, an upper right region and a lower right region, each region is an image to be displayed by one of the screens, and each region includes a target image unit.
Through the multi-screen display method in fig. 1, if the GPU and the window manager are not all started (for example, during the uboot phase), the SOC or the terminal may obtain the multi-screen display picture stored in the first partition from the first partition, and segment the obtained multi-screen display picture to obtain a plurality of target image units (for example, the start-up 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, the GPU and the window manager are not completely started, and a plurality of screens coupled by the SOC can be normally displayed.
In an embodiment, the size of the target image cells is the same, and after the dividing the target image cells from the multi-screen display picture in step S102 in fig. 1, the method may further include: processing each target image unit obtained by segmentation according to the size of the corresponding screen to obtain a target image unit for display, wherein the processing comprises one or more of zooming in, zooming out and line-row conversion; step S103 of displaying each target image unit obtained by segmentation on a corresponding screen may include: and displaying the target image unit for display on a corresponding screen.
Optionally, the sizes of the target image units in the multi-screen display picture stored in the first partition are the same, and when the sizes of the areas of the target image units displayed on the multiple screens are also the same, the target image units may be subjected to the same processing of enlarging, reducing, or performing line-row conversion, so as to achieve the same display effect on each screen.
Optionally, the sizes of the target image units in the multi-screen display picture stored in the first partition are the same, and when the sizes of the areas of the multiple screen display target image units are different, the target image units corresponding to different screens may be subjected to different processing such as enlarging, reducing, or line-row conversion according to the sizes of the screen display areas, so as to achieve the display results of the screens.
In an embodiment, referring to fig. 1 and fig. 3, fig. 3 is a schematic diagram of another multi-screen displaying method according to an embodiment of the present invention, and compared to fig. 1, before the step S101 of fig. 1 of obtaining a multi-screen display picture from a first partition, the method may further include: and S301, judging whether the current single-screen testing stage is the single-screen testing stage, if the judgment result of the S301 is negative, jumping to the S101, and executing the S101 to the S103.

For convenience of explanation, the screen displayed in the single-screen test stage is referred to as a target screen.
Alternatively, if the determination result in step S301 in fig. 3 is yes, the process jumps to step S302, and step S302 and step S303 are executed. Step S302, acquiring a single-screen display picture from a second partition, wherein the single-screen display picture comprises a single target image unit; step S303, displaying the target image unit in the single-screen display picture on one of the screens; wherein the first partition is different from the second partition.
The second partition is used for storing a single-screen display picture (such as a single-screen boot LOGO), and other explanations of the second partition can be referred to the first partition. The second partition may be the same partition as the first partition, and at this time, the SOC acquires the single-screen display picture or the multi-screen display picture according to the storage address of the single-screen display picture and the multi-screen display picture in the partition. Or the first partition and the second partition are different partitions, and at this time, the SOC acquires a single-screen display picture or a multi-screen display picture from the respective stored partitions.
The single-screen display picture is a picture only used for displaying the target screen, and the picture comprises a single target image unit (such as a single LOGO), so that the SOC or the terminal can display the target image unit in the single-screen display picture on the target screen.
When the GPU and/or the window manager are not completely started (such as uboot phase) and the SOC is in the single-screen test phase, only the target screen needs to display, the SOC obtains a single-screen display picture from the second partition, the single-screen display picture is amplified, reduced, subjected to line-row conversion and the like according to factors such as the size of a display area on the target screen, and the processed single-screen display picture is displayed on the target screen, so that a single target image unit is displayed on the target screen.
