All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, with the development of display screen technology, the application of a color screen on wearable equipment becomes standard configuration, the requirements for functions and interaction experience are higher, but the color is more than the data processed by a monochrome processor, and the data is limited by the main frequency, the memory space, the acceleration of non-graphic hardware and the cost of a main control chip, so that the display efficiency of a display system of the wearable equipment is lower on the basis of the existing main control chip, and the user experience is reduced. Based on this, the embodiment of the invention provides a data display method, a data display device and electronic equipment, and the technology can be applied to applications needing to display data.
In order to facilitate understanding of the embodiment, a detailed description is first given of a data display method disclosed in the embodiment of the present invention; the method is applied to wearable equipment; the wearable device includes: the system comprises an interface processing module, a resource loading module and a content caching module; the interface processing module and the resource loading module are respectively connected with the content cache module; the content caching module comprises at least one first caching block and at least one second caching block; the cache content in the first cache block can not be deleted, and the cache content in the second cache block can be deleted; the first cache block is pre-stored with main interface data of the wearable device, and the second cache block is pre-stored with sub-interface data of the wearable device except the main interface data;
as shown in fig. 1, the method comprises the steps of:
and S102, reading main interface data of the wearable device from the first cache block through the interface processing module, and displaying the main interface data through the display screen.
And step S104, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through the display screen.
Referring to fig. 2, a schematic structural diagram of a wearable device is shown, in fig. 2, including: the system comprises a main interface, a function interface, a notification interface, an interface manager (corresponding to the interface processing module), a graphic library, a resource loader (corresponding to the resource loading module), an input subsystem, a content cache module and a display screen driving module (corresponding to the display screen). The input subsystem also includes a key drive and a touch screen drive. Wherein, the function interface and the notification interface belong to the sub-interfaces.
The content caching module is a caching pool, namely all available caching spaces; referring to the schematic structural diagram of a content caching module shown in fig. 3, a cache pool is divided into a plurality of cache blocks and a cache linked list; the cache block caches different contents according to different interfaces or display contents. The cache pool is provided with a fixed cache block (corresponding to the first cache block) and a releasable cache block (corresponding to the second cache block), the cache content of the fixed cache block cannot be deleted, the cache content of the releasable cache block can be deleted, the cache linked list is a directory of the cache blocks, and the logical sequence of the cache blocks is adjusted according to the use frequency and the current interface so as to improve the searching efficiency of the cache. The content caching module is used for caching the content to be displayed on the display screen in different modes, so that the aims of frame rate and experience optimization can be fulfilled.
The main interface is generally an interface displayed after the system is started and an interface which can be directly switched in a sliding manner in the transverse direction and the longitudinal direction, belongs to a first-level interface and is also an interface which appears at the highest frequency; the interface manager can rapidly read and display the whole screen content from the cache module when achieving the sliding switching interface by accessing a main interface cache mechanism, thereby reducing the reading time; meanwhile, the interface manager can perform cache locking on the main interface through the interface provided by the content cache module, and the interface is guaranteed not to be destroyed in the background.
The function interface is generally an interface entered by clicking an application icon, the reminding interface is generally a notification interface, and the function interface and the notification interface are both directly jumped. Because the capacity of the cache pool is limited, all interfaces of the device cannot be cached, and therefore, for the sub-interfaces, a resource cache is selected, and display elements used in each sub-interface are generally cached in a releasable cache block, so that the resource loading times are reduced and the reading speed is improved.
The resource loader is a module for reading pictures and characters. In practical implementation, the resource loader reads the sub-interface resource by calling the interface of the content cache module, and then quickly displays the sub-interface resource through the display screen. When the resource exists in the cache, the resource loader reads the resource data from the content cache module more quickly, and when the resource does not exist in the cache, the content cache module reads the resource data from a FLASH (which can be understood as hardware), applies a cache block with a corresponding size from the cache pool for storing the resource data, and transmits the cache block to the resource loader.
The data display method is applied to wearable equipment, and the wearable equipment comprises the following steps: the wearable device comprises an interface processing module, a resource loading module and a content caching module, wherein the interface processing module and the resource loading module are respectively connected with the content caching module, the content caching module comprises at least one first caching block and at least one second caching block, and main interface data of the wearable device are stored in the first caching block in advance and cannot be deleted; the second cache block stores the sub-interface data except the main interface data in advance. Reading main interface data of the wearable device from the first cache block through an interface processing module, and displaying the main interface data through a display screen; the sub-interface data are read from the second cache block through the resource loading module, the sub-interface data are displayed through the display screen, in the mode, the main interface data are stored in the first cache block, the sub-interface data are stored in the second cache block, the display efficiency of the interface data can be improved by reading related data from the cache, and the display efficiency of the interface data can be further improved due to the fact that the using frequency of the main interface data is high, and the main interface data stored in the first cache block cannot be deleted.
The embodiment of the invention also provides another data display method, which is realized on the basis of the method of the embodiment; in the method, if the sub-interface data contains pictures and characters at the same time, the content cache module stores the mapping relation between the pictures and the characters in the sub-interface data, and the pictures and the characters with the mapping relation are stored adjacently; the method comprises the following steps:
step one, reading main interface data of the wearable device from a first cache block through an interface processing module, and displaying the main interface data through a display screen.
Specifically, the main interface data may be stored in the first cache block by the following step a:
step a, when a first power-on instruction is received, loading main interface data through an interface processing module, and storing the main interface data into a first cache block.
Generally, the hardware resources of the small wearable device are limited, so that the interfaces cannot be displayed in a superposed manner, only one interface is in a created and displayed state at any moment, so that the switching between the interfaces can have the operations of destroying the old interface and creating a new interface, images and font resources used in the interfaces need to be initialized during creating, and the resources need to be stored in an internal memory.
For the main interfaces, the number of the main interfaces can be multiple, but is generally within 8, the capacity of a cache pool is fixed according to hardware selection, the size of a cache block is dynamically applicable, and the size of each main interface is a known fixed screen size, so that the size of the cache block can be estimated.
Referring to fig. 4, according to the type selection of the cache pool, different space capacities and cache allocation strategies, each main interface may dynamically apply for a cache block of a screen size, the main interface is locked and resides in a fixed cache block, and an interface needs to be preloaded and stored in a cache before the system is started, and specifically, when a boot animation is displayed on power, the display content of the main interface is prepared after the boot animation is played at the same time by using an animation playing interval, so that the interface can respond to user operations fastest without waiting for a creation process, and due to the resident cache property of the interface, the repeated destruction and creation process of the interface is not involved when the main interface is switched back and forth.
And step two, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through the display screen.
Specifically, the sub-interface data is stored in the second cache block by the following steps b and c:
b, according to the size information of the display elements in the sub-interface data, acquiring a target cache region matched with the size information from a cache region except the first cache block in the content cache module through the resource loading module, and determining the target cache region as a second cache block corresponding to the display elements;
step c, storing the display elements into the corresponding second cache blocks; wherein the display elements comprise pictures and/or characters in the sub-interface data.
The display elements, that is, the resources, include pictures and fonts used in the sub-interfaces, and the display elements of all the sub-interfaces share all the cache spaces in the cache pool except the cache space locked by the main interface. Referring to fig. 5, a schematic diagram of a sub-interface resource caching method is shown, where each resource (picture or font) in a sub-interface dynamically applies for picture cache blocks or font cache blocks of different sizes from all cache spaces in a cache pool except that the cache space is locked by a main interface according to the size of the resource, and stores the picture or font into a corresponding picture cache block or font cache block.
The content cache module (corresponding to the cache pool) also comprises a cache linked list; the cache linked list stores first identification information corresponding to a main interface in each first cache block (corresponding to the fixed cache block), and second identification information corresponding to sub-interface data (corresponding to display elements of the sub-interface) in each second cache block (corresponding to the picture cache block or the font cache block).
Therefore, the cache linked list can be responsible for maintaining the sequence of the cache blocks corresponding to each main interface, keeping the main interface search path between adjacent interfaces to be nearest forever so as to improve the efficiency, and can also carry out content maintenance and replacement of the cache blocks so as to ensure that the common content of the current sub-interface can be cached to the maximum extent so as to improve the access speed. Meanwhile, the cache linked list can be related nearby according to the pictures and the fonts in the same sub-interface, namely the pictures and the fonts in the same sub-interface can be automatically adjusted to the front of the cache pool, and the searching hit rate of resources and fonts in the same sub-interface is improved.
In practical implementation, if a picture and characters exist in the display element at the same time, when a specified picture in the sub-interface data is loaded through the resource loading module, the specified characters having a mapping relation with the specified picture are loaded at the same time, and the specified characters are displayed at the specified position of the specified picture according to the mapping relation.
Specifically, N pictures are cached in the picture cache block, M groups of fonts are cached in the font cache block, the N pictures and the M groups of fonts have a mapping relation, when one or more pictures in the N pictures are loaded, one or more groups of fonts in the M groups of fonts are automatically loaded according to the mapping relation, the fonts also correspond to the positions of the pictures, and when the pictures are loaded, corresponding characters are loaded and displayed according to the mapping relation and the position relation of the fonts.
In actual implementation, if the display element includes a character, the second cache block corresponding to the display element also stores dot matrix information corresponding to the character.
In actual implementation, if the display element comprises a character and the character is not displayed in the display screen, the second cache block corresponding to the display element stores character information associated with the character; wherein the character information includes: size information and encoding information of the character.
For some scenes, it may not be necessary that the characters are actually displayed on the screen, but size information and/or lattice information (graphic information of the characters) of the characters are used, and the content caching module may determine a next sliding behavior of the user according to a sliding/operating behavior of the user on the current interface, and determine whether a font caching mode is to cache the character information or the lattice information according to the next sliding behavior of the user. Fig. 6 is a schematic diagram of a text exceeding the display range, when the text exceeds the display range, the text does not need the lattice information of the characters, that is, when the characters are not displayed on the screen, only the information of the size, the code, and the like of the characters of the text is cached, and the total maximum draggable size is calculated according to the information of the size of the characters so as to be used for the typesetting calculation. The cache mechanism can save memory space, achieve high utilization rate and improve the hit rate of the character lattice data cache. Because the occupied space of the character information is less, the character information can be put into an internal RAM (random access memory) cache, and the RAM is used for exchanging data with a CPU or temporarily storing the data. Cache is only one use of RAM. For example, opening a file requires caching the file content with RAM, so that the file content can be modified and stored in FLASH (hard disk). The internal RAM refers to the space available for caching inside the main control chip, and the access speed of the RAM is far higher than that of the external RAM because the RAM is inside the chip.
Specifically, referring to a schematic diagram of a cache mechanism of character information shown in fig. 7, for a character "you", the size information of the cache is "16 wide" and "16 high"; the buffered coding information is "code ═ 0 × 1". For the character "good", the size information of the buffer is "16 wide and 16 high"; the buffered coding information is "code ═ 0 × 2". The sequence of character caching is realized by maintaining the content and the sequence of the cache linked list, the cache linked list can sequentially adjust the cached content in the next interface according to the current interface so as to improve the cache searching speed, in addition, the characters have no other special cache rules, and the character with the highest use frequency is positioned at the forefront of the cache linked list.
The file processing method is applied to wearable equipment, and the wearable equipment comprises the following steps: the system comprises an interface processing module, a resource loading module and a content caching module, wherein the interface processing module and the resource loading module are respectively connected with the content caching module, and the content caching module comprises at least one first caching block and at least one second caching block. When a first power-on instruction is received, main interface data are loaded through the interface processing module and stored in the first cache block, so that the interface can respond to user operation at the fastest speed without waiting for a creation process; acquiring a second cache block through the resource loading module, and storing the display element into the corresponding second cache block; the frequency of resource loading can be reduced, and the reading speed is improved; the content caching module comprises a caching linked list; the cache linked list stores first identification information corresponding to the main interface data in each first cache block and second identification information corresponding to the sub-interface data in each second cache block, and the cache linked list maintains and replaces the contents of the cache blocks to ensure that the common contents of the current sub-interface can be cached to the maximum extent so as to improve the access speed. Meanwhile, the cache linked list can be related nearby according to the pictures and fonts in the same interface, namely the pictures and the fonts in the same interface can be automatically adjusted to the front of the cache pool, and the search hit rate of resources and fonts in the same interface is improved.
The embodiment of the invention also provides another data display method, which is realized on the basis of the method of the embodiment; as shown in fig. 8, the method includes the steps of:
step S202, main interface data of the wearable device are read from the first cache block through the interface processing module, and the main interface data are displayed through the display screen.
The primary interface data comprises time interface data; the first cache block corresponding to the time interface data comprises: hour hand cache block, minute hand cache block and second hand cache block.
In wearable devices, the time interface often needs to display different styles of time, such as a display with a pointer. Because the pointer is limited by hardware performance and storage space, the pointer needs to be rotated, the operation is extremely labor-consuming, and the time interface is generally a primary main interface, which results in poor device interaction experience. According to the characteristics of the hand clock, the occurrence frequency of the time hand, the minute hand and the second hand which need to be changed simultaneously is only once an hour, and only the second hand moves in most cases.
Specifically, referring to a schematic diagram of a time interface caching method shown in fig. 9, the hour, minute and second hands dynamically apply for corresponding hour hand cache blocks, minute hand cache blocks and second hand cache blocks from a cache pool according to the size of images of the hour, minute and second hands, each rotated hand is fixedly cached in a cache block with the size of the hand and is not released, the rotated hour hand is fixedly cached in the hour hand cache block, the rotated minute hand is fixedly cached in the minute hand cache block, and the rotated second hand is fixedly cached in the hand cache block, so that the second hand does not need to be rotated every time of displaying, the sequence of each hand cache block is maintained through a cache list, and target cache data is quickly found so as to control the display of three hands.
And step S204, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through the display screen.
Step S206, aiming at each main interface data, if the data content in the main interface data is larger than the displayable area corresponding to one display screen, performing paging processing on the data content in the main interface data through an interface processing module according to preset partition granularity to obtain a plurality of paging data corresponding to the main interface data;
in step S208, each paging data is stored in the corresponding first cache block.
When the appointed content in the main interface data needs to be displayed, acquiring appointed paging data corresponding to the appointed content; specified paginated data is synthesized and displayed.
In general, a long text interface is also present in the primary main interface. For example, if the product definition main interface includes a squared menu list, it will also be an interface with pictures and texts and larger than one screen of content. Under the condition, the main interface data division granularity (cache length) needs to be subjected to paging cache, paging composition is carried out during display, cached paging data are combined into one screen of data to be displayed, the whole data exceeding one screen does not need to be read, data reading is reduced, and the efficiency of displaying the data is improved.
