The method provided by the first embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Fig. 1 shows a hardware configuration block diagram of a computer terminal (or mobile device) for implementing a screen display method. As shown in fig. 1, the computer terminal 10 (or mobile device 10) may include one or more (shown as 102a, 102b, … …, 102 n) processors 102 (the processors 102 may include, but are not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), and memory 104 for storing data. Besides, the method can also comprise the following steps: a transmission module, a display, an input/output interface (I/O interface), a Universal Serial Bus (USB) port (which may be included as one of the ports of the I/O interface), a network interface, a power source, and/or a camera. It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic device. For example, the computer terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

It should be noted that the one or more processors 102 and/or other data processing circuitry described above may be referred to generally herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part in software, hardware, firmware, or any combination thereof. Further, the data processing circuit may be a single stand-alone processing module, or incorporated in whole or in part into any of the other elements in the computer terminal 10 (or mobile device). As referred to in the embodiments of the application, the data processing circuit acts as a processor control (e.g. selection of a variable resistance termination path connected to the interface).

The memory 104 may be used to store software programs and modules of application software, such as program instructions/data storage devices corresponding to the screen display method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implements the screen display method of the application program.

It should be noted that fig. 1 is only one example of a particular specific example and is intended to illustrate the types of components that may be present in the computer device (or mobile device) described above.

In some applications, a controller with low memory may be used to drive a larger screen. For example, in an electronic price tag project, in order to use a low-memory MCU to drive a 7.5-inch or even higher screen, a relatively large RAM space is required for the frame buffer. For example, a 7.5 inch panel is 640 pixels wide and 384 pixels tall. The size of Framebuffer for a black and white screen is 640 x 384/8-30720 (30K) bytes. The memory required is doubled if picture rotation or line-column conversion is required, so that even if the MCU of an STM32L433CC is configured as 256K Flash and 64K RAM, it cannot drive this size screen.

In the related art, the data to be displayed may be directly transmitted to the display device serially byte by byte without using Framebuffer. The disadvantage of this approach is that there is no way to use graphical functions, e.g., display rotation, graphical overlays, etc.

Under the above operating environment, the present application provides a screen display method as shown in fig. 2. Fig. 2 is a flowchart of a screen display method according to embodiment 1 of the present invention. As shown in fig. 2, the method comprises the steps of:

step S202, dividing the data to be displayed on the screen into a plurality of blocks.

As an alternative embodiment, the execution subject of the above steps may be the above-mentioned micro control unit MCU.

As an alternative embodiment, the screen may be a screen for displaying on a display device, which may be displayed by other displays.

As an optional embodiment, since the data amount of the screen is too large, and the memory required by the display device is too small to display, the data to be displayed on the screen is divided into a plurality of blocks, and each block can be separately accommodated in the memory, so that the memory can at least store and transmit a single block at a time. The screen can be sent to the display device for multiple times without data loss.

Step S204, respectively reading the data to be displayed on a preset number of blocks in the plurality of blocks through the memory, and respectively sending the data to the frame buffer area of the screen of the display device for the display device to control the screen to display, wherein the size of the memory is smaller than that of the frame buffer area of the screen.

As an alternative embodiment, the execution subject of the above steps may be an MCU. Dividing the data to be displayed on the screen into a plurality of blocks, writing the data to be displayed on the plurality of blocks into the memory for a plurality of times by combining with a plurality of times of writing and erasing of the memory, and respectively sending the data to be displayed on the plurality of blocks into the display equipment by the memory so as to be displayed by the display equipment.

As an optional embodiment, the reading of the data to be displayed on the predetermined number of blocks in the plurality of blocks through the memory may be performed by reading the data to be displayed on each block one by one according to the order of the blocks. It should be noted that the predetermined number of blocks may also be the above-mentioned plurality of blocks, that is, all blocks in the plurality of blocks, that is, the predetermined number of screen blocks are the above-mentioned plurality of blocks, and according to the sequence, the plurality of blocks may constitute the screen on the display device.

As an optional embodiment, the data to be displayed on a predetermined number of blocks in the plurality of blocks may be read through the memory, or the data to be displayed on the plurality of blocks may be read according to a random sequence and sent to the display device through the memory. Similarly, the predetermined number of screen number blocks may be the plurality of blocks, and the predetermined number of screen number blocks may be received by the display device, sorted and combined, restored, and displayed.

As an optional embodiment, the data to be displayed on the predetermined number of the multiple blocks in the multiple blocks are respectively read through the memory, and the blocks may be selected from the multiple blocks according to the display requirement to read and transmit the data to be displayed, that is, the predetermined number of the blocks may be one or more blocks in the multiple blocks, so that the flexibility of use is high, and the method is suitable for more display occasions.

As an optional embodiment, when the data to be displayed on the multiple blocks are sent one by one according to the order of the blocks, the data to be displayed on the multiple blocks are sent to the display device one by one according to the order, and the display device may sort the data to be displayed according to the receiving order of the multiple blocks and then display the data on the screen.

As an optional embodiment, the data to be displayed on the multiple blocks is sent to the display device according to a random order, and after the screen device receives the data to be displayed on the multiple blocks, the order of the received data to be displayed on the multiple blocks may be adjusted, and the data to be displayed is displayed on the screen according to the adjusted order.

As an alternative embodiment, the size of the memory is smaller than the size of the frame buffer of the screen. It should be noted that the "size of the frame buffer of the screen" described herein refers to the size of the frame buffer being a memory area capable of displaying the whole screen, and this memory area is not necessarily required, and may be understood as a virtual memory area, which is not required in the embodiment of the present invention. And the problem that a large memory is needed for displaying a large screen is solved by adopting a smaller memory. Because the memory used in the embodiment of the invention is smaller than the large memory required by the large screen display, and the small memory can also display the large screen, the problem of insufficient memory in the related technology is effectively solved.

In the related art, when the size of the memory is smaller than the frame buffer, the size of the memory is smaller than the data size of the entire screen, and the entire screen data cannot be buffered in the frame buffer at one time.

Compared with the method for dividing the data to be displayed on the screen by using the size smaller than the memory, when the data to be displayed on the screen is divided by using the size smaller than the memory, the smaller the data amount of the blocks is, the more the number of the blocks of the data to be displayed on the screen is, the more the memory writes and erases, and the lower the data writing speed is.

As an optional embodiment, for the reason described above, the data amount of the partition should be as large as possible when allowed, and therefore, in this embodiment, the data to be displayed on the screen partition is divided into a plurality of partitions by taking the size of the memory as a unit, so as to ensure that the size of the divided partitions is equal to the size of the memory, except for the last partition left by the division, and the size of the last partition left by the division depends on whether the size of the data amount of the screen is evenly divided by the size of the memory.

As an alternative embodiment, when the size of the data amount of the screen is divisible by the size of the memory, the size of the last block of the partition is the same as the size of the memory, and the sizes of other blocks. If the size of the data size on the screen is not evenly divisible by the size of the memory, the size of the last divided block is smaller than the size of the memory and the sizes of other divided blocks. But also not in the way, the memory can perform read operation and write operation once.

The memory reads data to be displayed on the plurality of blocks in a partitioning manner from the controller for partitioning the screen, and respectively sends the data to be displayed to the frame buffer area of the screen of the display device for the display device to control the screen to display.
