Description

Technical Field

[0001] The present application relates to the field of image display technology, and in particular to a screen display control method and device, electronic equipment, and storage medium. Background Art

[0002] Currently, many heat-not-burn appliances are equipped with LCD screens. Various desired images can be displayed on the LCD screens on the heat-not-burn appliances, such as images reflecting battery charging.

[0003] Current heat-not-burn appliances generally use flash chips to save images. When there is a need to display an image, the main control chip of the heat-not-burn appliance will first chip-select the flash chip to read the image to be displayed from the flash chip in the chip-selected state and cache it in the main control chip. Then the LCD screen is chip-selected, and the cached image and the display address of the image stored in the main control chip are transmitted to the LCD, so that the LCD screen in the chip-selected state can use the transmitted information to display the image on the LCD screen.

[0004] However, since image data generally occupies a relatively large capacity, caching the image data in the main control chip will occupy a large cache space of the main control chip. In addition, it takes a long time to read the image from the flash chip and cache it, and to transmit the cached image to the LCD screen, which results in the screen display not being able to be refreshed in time. Summary of the invention

[0062] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0064] The present application embodiment provides a method for controlling screen display, such as Figure 1 As shown, the following steps are included:

[0065] S101, after the heating without burning appliance is started, a flash chip and an LCD screen in the heating without burning appliance are chip-selected.

[0066] Among them, the output pin of the flash chip is directly connected to the input pin of the LCD screen. Because in the screen display control method provided in the embodiment of the present application, it is necessary to directly transmit the data read by the flash chip to the LCD screen without caching through the main control chip. In order to allow the flash chip to directly transmit data to the LCD screen, in the embodiment of the present application, the output pin of the flash chip is directly connected to the input pin of the LCD screen, so that data can be directly output from the flash chip to the LCD screen. In addition, in order to ensure that the flash chip and the LCD screen can transmit data, that is, communicate, it is necessary to ensure that the communication protocol of the output pin of the interconnected flash chip is consistent with the output pin of the LCD screen.

[0067] Since the chip in the heating without burning device needs to be controlled to operate, it needs to be set to a chip select state. In the embodiment of the present application, data needs to be read from the flash chip and directly transmitted to the LCD screen for display, so the main control chip in the heating without burning device needs to simultaneously select the flash chip and the LCD screen, instead of sequentially selecting them.

[0068] Optionally, in another embodiment of the present application, after executing step S101 and before executing step S102, the LCD screen may be initialized. Figure 2 As shown, an LCD screen initialization method provided in an embodiment of the present application includes the following steps:

[0069] S201, finding out the storage start address and total data length of the initialization command.

[0070] In the embodiment of the present application, the initialization command is stored in the flash chip, and only the storage address and data length of the initialization command in the flash chip are stored in the main control chip, thereby avoiding occupying the storage space of the main control chip. Therefore, when the initialization command is needed, it is necessary to first find out the storage start address and total data length of the initialization command, and then execute step S202.

[0071] S202: Read all initialization commands from the flash chip based on the storage start address and total data length of the initialization commands.

[0072] Specifically, the main control chip requests the flash chip to read data of the total data length from the data stored in the flash chip starting from the storage start address of the initialization command found by the main control chip, so that all the initialization commands can be read out.

[0073] S203, transmitting the read initialization command to the LCD screen through the pins connected between the flash chip and the LCD screen, so as to trigger the LCD screen to perform screen initialization using all the initialization commands.

[0074] Specifically, after requesting the flash chip to read the initialization command, the main control chip will let the flash chip transmit the read initialization command directly to the LCD screen through the pins connecting the flash chip and the LCD screen without passing through the main control chip. After receiving the initialization command, the LCD screen uses the initialization command to initialize the screen.

[0075] S102: Detect in real time whether there is a demand for image display.

[0076] Optionally, the user may trigger the image display requirement by pressing a button.

[0077] When an image display requirement is detected, step S103 is executed.

[0078] S103: Find out the storage start address and total data length corresponding to the current target image requested to be displayed by the current image display requirement.

[0079] It should be noted that in order to allow the LCD screen to directly obtain data transmitted by the flash chip to display images, in an embodiment of the present application, the data required for displaying each image is stored in the flash chip in advance, and the storage start address and total length of this data are stored in the main control information chip.

[0080] Therefore, when an image needs to be displayed, the storage start address and total data length corresponding to the current target image requested to be displayed by the current image display requirement are found from the storage start address and total data length corresponding to each image, and then step S104 is executed.

[0081] Optionally, in another embodiment of the present application, a specific implementation of step S103 is as follows: Figure 3 As shown, the following steps are included:

[0082] S301. Determine, according to a service code that triggers a current image display requirement, an image identifier of a current target image requested to be displayed by the image display requirement.

[0083] It should be noted that, in order to identify different images, in the embodiment of the present application, an image identifier of a position is set for each image. Since the images required to be displayed when executing different business codes are usually determined, the image identifier of the current target image requested to be displayed by the image display requirement can be determined based on the business code that triggers the current image display requirement.

[0084] S302: According to the image identifier of the current target image, find out the storage start address and total data length corresponding to the current target image from the data of each stored image.

[0085] Optionally, the image identifier of each image may be associated with the storage start address and total data length corresponding to the image, so that the storage start address and total data length corresponding to the current target image may be found out based on the association relationship.

[0086] Optionally, in another embodiment of the present application, considering high frequency operation and different triggered image display requirements, in order to avoid conflicts among various image display requirements and ensure that various image display requirements can be responded to, before executing step S103, further analysis and processing of the display status of the LCD screen may be performed. Figure 4 As shown, a display state analysis and processing method of an LCD screen provided in an embodiment of the present application includes the following steps:

[0087] S401, determining whether the LCD screen is currently in a display idle state.

[0088] If it is determined that the LCD screen is not currently in the display idle state, step S402 is executed. If it is determined that the LCD screen is currently in the display idle state, step S403 is executed.

[0089] S402: Queue the current image display requirements.

[0090] Since the LCD screen is currently processing the display of other images, the current image display requirement can only be queued. Optionally, the identification of the image requested to be displayed by the current image display requirement can be used to queue.

[0091] S403, clearing the display idle state of the LCD screen.

[0092] Since there is no display processing of other images at this time, the current image display demand can be processed, and in order to avoid the influence of subsequent other image display demands, the display idle state of the LCD screen is cleared, that is, the display state of the LCD screen is no longer an idle state. And, while executing step S403, step S103 can be executed.

[0093] S104 , starting from the storage start address corresponding to the current target image in the flash chip, data is read according to the total data length corresponding to the current target image to obtain image data of the current target image.

[0094] The image data of the current target image includes the pre-stored screen display address of the current target image, the screen communication instruction, and the current target image. Specifically, in the embodiment of the present application, the data of each image is stored in a partition in the flash chip, specifically including the address of its display on the screen, that is, the screen display address, the screen communication instruction, and the image.

[0095] Optionally, the communication instruction, the start address and the end address of the screen display address and the display data can be packaged and stored in the flash chip. For example, 0x2A is to send the x-axis address followed by the high eight bits, low eight bits, and the end address high eight bits and low eight bits of the x-axis start address, and 0x2B is to send the y-axis address followed by the high eight bits, low eight bits, and the end address high eight bits and low eight bits of the y-axis start address, so the specific format can be: {0x2A, 0x00, 0x12, 0x00, 0x82, 0x2B, 0x09, 0x19, 0x0A, 0x0B,......}.

[0096] Specifically, the main control chip controls the flash chip to read data from the location of the storage start address corresponding to the current target image in the flash chip according to the total data length corresponding to the current target image, thereby reading the image data of the current target image.

[0097] S105, the image data of the current target image read is transmitted from the flash chip to the LCD screen through the pins connecting the flash chip and the LCD screen, so as to trigger the LCD screen to respond to the screen communication instructions in the image data of the current target image, and display the current target image on the LCD screen according to the screen display address of the current target image.

[0098] Specifically, the image data of the current target image read from the flash chip is directly transmitted from the flash chip to the LCD screen through the pins connecting the flash chip and the LCD screen, and no longer passes through the main control chip. After receiving the image data of the current target image, the LCD screen will respond to the screen communication instruction in the image data of the current target image and display the current target image on the LCD screen according to the screen display address of the current target image.

[0099] Optionally, when display control needs to be performed through display status, in another embodiment of the present application, after executing step S105, the following may be further performed:

[0100] Set the LCD screen to an idle state and determine whether there is a queued image display demand.

[0101] If it is determined that there is a queued image display demand, the first-ranked image display demand is used as the current image display demand, and the process returns to step S103 for the current image display demand.

[0102] The embodiment of the present application provides a method for controlling screen display. After the heating-without-burning device is started, the flash chip and the LCD screen in the heating-without-burning device are chip-selected so that data can be read from the flash chip at the same time and directly displayed on the LCD screen. Among them, the output pin of the flash chip is directly connected to the input pin of the LCD screen, so that the flash chip can communicate directly with the LCD screen. Then, it is detected in real time whether there is an image display demand. When the image display demand is detected, the storage start address and the total data length corresponding to the current target image requested to be displayed by the current image display demand are found. Then, starting from the location of the storage start address corresponding to the current target image in the flash chip, data is read according to the total data length corresponding to the current target image to obtain the image data of the current target image. Among them, the image data of the current target image includes the pre-stored screen display address of the current target image, the screen communication instruction and the current target image. Finally, the image data of the current target image read is directly transmitted from the flash chip to the LCD screen through the pins connecting the flash chip and the LCD screen, so as to trigger the LCD screen to respond to the screen communication instructions in the image data of the current target image, and display the current target image on the LCD screen according to the screen display address of the current target image, thereby directly transmitting the data read by the flash chip to the LCD screen for display, and there is no need to cache it in the main control chip first, so there is no need to occupy the cache space of the main control chip, and the data can be transmitted quickly for image display, effectively improving the refresh speed of the screen.

[0103] Another embodiment of the present application provides a device for controlling screen display, such as Figure 5 As shown, including:

[0104] The chip selection unit 501 is used to select the flash chip and the LCD screen in the heat without burning appliance after the heat without burning appliance is started.

[0105] Among them, the output pins of the flash chip are directly connected to the input pins of the LCD screen.

[0106] The detection unit 502 is used to detect in real time whether there is a demand for image display.

[0107] The first search unit 503 is used to search for the storage start address and total data length corresponding to the current target image requested to be displayed by the current image display requirement when an image display requirement is detected.
