At this point, the exemplary system architecture 100 may also not include the server 105 and the network 104.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for an implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a display method for an image according to the present application is shown. The display method for the image comprises the following steps:
In this embodiment, an execution subject (for example, the server 105 shown in fig. 1) of the display method for the image may obtain the display instruction from an external processor integrated locally with respect to the execution subject or other non-local external processors (for example, the terminal devices 101, 102, 103 shown in fig. 1), which is not limited in this application.
The display instruction usually includes an operation instruction for instructing an execution main body (hereinafter referred to as a display main body) of a display method for an image to display image data, target image data and a storage position of the target image data, and after receiving the display instruction, the display main body can read the content in the display instruction, determine the target image data, generate a corresponding image data acquisition request according to the storage position of the target image data, and send the corresponding image data acquisition request to a corresponding memory so as to control the memory to send the corresponding image data to the display main body.
It should be understood that the external processor is a concept related to the display main body, if the display main body is a server, the external processor may be a different unit simultaneously disposed in the server to implement a function different from that of the display main body, and after receiving instruction information transmitted from a terminal device used by a user, for example, the external processor generates a corresponding display instruction and transmits the display instruction to the display main body, or may be disposed in another external terminal, and directly implement the purpose of transmitting the display instruction to the display main body by communicating with the server through the network 104 shown in fig. 1, for example.
Similarly, the display main body may be a terminal, the external processor may be a corresponding server, and after the terminal receives the display instruction sent by the server, the terminal locally generates a corresponding image data acquisition request and sends the request to the memory.
The display main body and the external processor can be usually set by adopting a single chip microcomputer, for example, when the display main body and the external processor are set in the same server or terminal equipment, for example, an ESP32 module can be adopted, and based on the dual-core characteristic of the ESP32, the display main body and the external processor respectively occupy one core, so that higher stability is achieved.
In this embodiment, after the display main body sends the image data acquisition request corresponding to the display instruction received in step 201 to the memory, the target image data sent from the memory and returned in response to the image data acquisition request is received, and image display control information for controlling the subsequent terminal to display the image data is generated according to the content of the target image data.
The target image data may be an image set including image content, encoding information for indicating display of the image content, and the like, and after receiving the target image data, the obtained image data may be encoded and stored according to an adaptation condition of a terminal for displaying the target image data, so as to generate image display control information.
In this embodiment, the flexible display terminal is generally generated by a control component and a display component, and after the image display control information is generated in step 202, the information is sent to the control component of the flexible display terminal, so that the control component of the flexible display terminal instructs the display component of the flexible display component to display the image according to the image display control information.
When the flexible display terminal is generated only by the display module, the image display control information that can be directly read by the display module is generated when the image display control information is generated in step 202, and the image control information generated in the display main body is, for example, a current pulse train, and when the current pulse train is transmitted to the display module, the display module can directly display the content according to the current pulse train.
According to the display method for the image, after a display instruction sent by an external processor is received, an image data acquisition request corresponding to the display instruction is sent to a memory; receiving target image data corresponding to the image data acquisition request returned by the memory, and generating image display control information according to the target image data; the image display control information is sent to the flexible display terminal, the flexible display terminal is controlled to display corresponding images according to the image display control information, and the two processors are matched to control the flexible display terminal to display the images, so that the flow efficiency and the presentation quality of image display are improved.
In some optional implementations of this embodiment, the memory includes an internal memory and an external memory; and the sending of the image data acquisition request corresponding to the display instruction to the memory includes: and in response to determining that the image data are stored in both the internal memory and the external memory, sending the image data acquisition request to the internal memory and the external memory in sequence.
Specifically, in order to facilitate the acquisition of the image data, the data is stored in the internal memory of the main body, but because the storage space of the general internal memory is limited, the image data can be pre-selected to be stored in the internal memory, the external memory or the internal memory and the external memory jointly according to the actual situation of the space occupied by the image data, and the image data is divided into two parts which are stored in the internal memory and the external memory respectively.
Illustratively, when a display instruction from an external processor is received, the display main body reads data corresponding to the display instruction from the external memory, retains single-frame data in the internal memory, and resolves the single-frame data into a data group required for dynamic refresh.
And then, the display main body transmits data to a control unit for controlling the flexible display terminal to display at a predetermined highest speed in a communication mode similar to a serial port, and after the single transmission is finished, a refresh is started.
In this process, the data required for the next refresh is also in a ready state, thereby ensuring that the time can be compressed to a minimum during the frame-to-frame switching process.
Therefore, after the display main body acquires the display instruction, the main body receiving the image data acquisition request is determined according to the indication condition in the display instruction, and when the internal memory and the external memory are determined to be jointly used, namely the internal memory and the external memory are determined to be stored with the image data, the image data acquisition request is sequentially sent to the internal memory and the external memory so as to realize partial image data from the internal memory and the external memory respectively and finally acquire complete image data, wherein the internal memory can store more critical information such as key information, synthesis guide information and the like of the image data due to small storage space, namely information corresponding to the functions of realizing the protection of important data and the matching of the important data to the external data, on the basis, the external memory can be used for storing data with larger occupied space and lower value relative to the internal memory, so that the balance of the functions and the storage space is realized by jointly using the internal memory and the external memory.
In some optional implementations of this embodiment, the method further includes: the external processor responds to the received incoming external control instruction and extracts original image data from the external control instruction; the external processor compresses the original image data to obtain compressed image data; the external processor sends the compressed image data set to the memory for storage.
Specifically, the external control command may be an external control command sent by a user, or may be an external control command that is input at regular time according to a predetermined input rule, or is sent in another manner, where the external control command may include related information such as position information of original image data, and is used to instruct an external processor to extract the original image data, and after the external processor receives an incoming external control command, the external processor reads data corresponding to the display command from a memory, retains single-frame data in an internal memory, resolves the single-frame data into a data group required for dynamic refresh, and compresses the data after extracting the original image data, so as to obtain compressed image data, and stores the data into the memory for subsequent display main body to obtain from the memory, so that when data is stored, repeated frames and animation segments in a single animation can be extracted, and parameters such as loops and subsequent animations are added in the playing process, thereby realizing more data storage in the same storage mode. Meanwhile, the method reduces the consumption of the memory and repeated application under the condition of high frame rate dynamic refreshing, and can realize the compression and storage of data in a distributed manner and reduce the execution burden of the display main body.
In some optional implementations of this embodiment, the method further includes, in response to receiving an update instruction, updating, by the external processor, the local content of the external processor according to the update instruction; wherein the local content includes at least one of: the updating instruction is acquired through an air downloading mode.
Specifically, communication, over-the-air (OTA), coding and decoding logic and the like can be fixed in a storage unit of an external processor or can be arranged in other processors independent of the external processor, and the other processors are set to run all the time from the start of the external processor through hardware communication such as a serial port and the like.
For example, a test mobile hotspot account is preset in the local memory of the external processor, and polling connection is performed after the logic starts to run or in a period of 5s, and the mechanism is also triggered when disconnection occurs. The default account number and the password can also be modified through communication modes such as a serial port and the like, and the modified account number and the password can take effect after being restarted. Once the mobile hotspot is successfully connected, the OTA mechanism is triggered, and OTA online upgrade can be successfully carried out in a specific mode.
In some optional implementations of this embodiment, generating image display control information from the target image data includes: storing each image data frame constituting the target image data into a latch frame by frame; the image display control information is generated by the latch in response to all frames of image data constituting the target image data being stored in the latch.
Specifically, the obtained target image data is continuously stored in the buffer according to the form of data, for example, the obtained target image data is a set of image frame data, and then the obtained target image data can be continuously stored in the latch frame by frame in sequence, when all the image data forming the target image data are determined to be stored in the latch, the image display control information is generated, and the image display control information is generated on the basis of the complete target image data through the form generated after the buffer, so that the problems of image blocking and image missing caused by lack of individual image data are avoided, and the image display process is complete and reliable.
With continued reference to fig. 3, there is shown a schematic structural diagram 300 of a flexible display terminal in another embodiment of a display method for images according to the present application, wherein the flexible display terminal comprises: the display component 301 and the control component 302 are in communication connection, the control component is horizontally arranged outside the display component, and the control component is used for controlling the display component to display a corresponding image according to received image display control information; the display assembly is arranged on the flexible substrate.
The display module 301 generally includes a lamp bead matrix 301a for displaying and a corresponding driving unit 301b, where the driving unit is generally divided into a column driving unit for column driving and a row driving unit for row driving, for example, when the lamp bead matrix is formed by independent LED lamp beads, the driving unit uses MBI5026 as a column driver, the column driver supports a maximum driving current of 90mA, can support a maximum 45 rows of LED lamp beads, each MBI5026 can support 16 columns of LED lamp beads, each column driving is independent of each other, and whether to use the lamp bead matrix or not can be selected according to a structural shape. A row driver adopts an 8-bit shift register of 74HC595D, in order to increase the driving capability of row current, each parallel data output is added with Si2301D, so that the maximum current of each row is 2.3A, and the display support of 1000 rows of LED lamp beads can be provided to the maximum extent through the cascade connection of MBI 5026.
The column driver MBI5026 is a 16-bit LED constant current driver. The Bi _ CMOS process is adopted for production, the constant current value can be adjusted by an external resistor (Iout = 5-90 mA).
