Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The TFT screen is a common liquid crystal display, and adopts a design of filling liquid crystal molecules between two interlayers, the left interlayer is set as a FET transistor, and the right interlayer electrode is set as a common electrode. In terms of light source design, a TFT screen adopts a back-transmission type illumination mode, namely an imaginary light source path is from right to left, the method is that a light tube similar to a fluorescent lamp is arranged on the back of liquid crystal, and when the light source is illuminated, the light source firstly transmits to the left through a right polarizer and conducts light by virtue of liquid crystal molecules. Because the electrodes of the left interlayer and the right interlayer are the FET electrode and the common electrode, when the FET electrode is conducted, the arrangement state of liquid crystal molecules can be changed, and the purpose of displaying is achieved through shading and light transmission. In addition, since the FET transistor has a capacitance effect and can maintain a potential state, the liquid crystal molecules that were previously transparent remain in this state until the FET electrode is next recharged to change its arrangement.
With the development of science and technology, the TFT screen has been popularized to thousands of households by virtue of its excellent performance, no matter being a household appliance or a personal computer, displaying images through the TFT screen is an indispensable function, and the screen needs to be refreshed again every time when a new image is displayed, the TFT screen is usually connected with the electronic device through MCU serial port communication, when the electronic device receives an image to be displayed, the image to be displayed needs to be firstly transmitted to the TFT screen through MCU serial port communication, and after the TFT screen receives the image data to be displayed, the newly obtained image to be displayed is displayed on the TFT screen within a certain refresh time.
However, during the screen refreshing process of the TFT screen through the MCU serial port communication, due to the transmission rate, a screen flashing phenomenon may occur in the refreshing process of a large-sized picture, and meanwhile, the running time of the main loop may be prolonged, so that the running time of the main loop is increased, which causes problems in other main loop functions.
In order to solve the above problems, embodiments of the present invention provide an electronic device, a screen display method and apparatus thereof, and a storage medium, in which an excessively large image to be displayed is divided by the screen display method of the electronic device, and divided sub-images to be displayed are sequentially displayed, so that a problem of screen flashing during a picture refresh process is effectively solved, and meanwhile, a running time of a main cycle during a screen refresh process is reduced, so that the running time of the main cycle is controlled within a maximum allowable time.
Fig. 1 is a flowchart of a screen display method of an electronic device according to an embodiment of the present invention. As shown in fig. 1, the screen display method of the electronic device includes the steps of:
step S101, obtaining the execution time of the electronic equipment executing the main control program once, wherein the execution time comprises the display time of the image to be displayed on the screen.
Specifically, the electronic device receives the information of the image to be displayed through the MCU serial port communication and displays the received image through the screen of the electronic device, after the electronic equipment receives new image information to be displayed, the screen of the electronic equipment updates and displays the received new image in a screen refreshing mode, the electronic equipment needs to run a main control program every time the electronic equipment receives the new image information to be displayed, the time required for the main control program to execute the instruction each time the main control program obtains the information of the image to be displayed is the execution time (abbreviated as execution time) for the electronic device to execute the main control program once, and it should be noted that the duration of the image to be displayed on the screen of the electronic device is included in the execution time, that is, the execution time includes both the display time of the image to be displayed and the instruction execution time of the preparation work except the display process.
As an embodiment, acquiring an execution time of the electronic device executing the main control program once includes: acquiring the size of an image to be displayed and the transmission rate of transmitting the image to be displayed to a screen; acquiring display time according to the size of the image and the transmission rate; and acquiring the execution time of the electronic equipment for executing the main control program once according to the display time and the instruction execution time of the main control program except the display time.
That is to say, when the execution time of the main control program of the electronic device is obtained, the duration of each time the image is displayed on the screen of the electronic device needs to be obtained first, specifically, the size of the image to be displayed communicated through the MCU serial port and the fixed data transmission rate of the communication interface are obtained, and the ratio of the size of the image to be displayed to the transmission rate is calculated according to the obtained size of the image to be displayed and the transmission rate of the MCU serial port communication, so that the display time of each time the image to be displayed on the screen of the electronic device can be obtained; besides, besides the duration of displaying the image on the screen of the electronic device, the running time of other main loops in the main control program, that is, the execution time of all other instructions in the main control program except the duration of displaying the image to be displayed, is also obtained, and the execution time of the electronic device executing the main control program once includes the display time of the image to be displayed on the screen of the electronic device and the execution time of all other instructions except the display time.
If the image to be displayed is too large, under the condition that the transmission rate is fixed, the data transmission time may be too long due to the picture, so that the screen flashing phenomenon of the electronic equipment screen may occur, and in addition, the picture data transmission time is too long, the execution time of other instructions in the main program is also occupied, so that other circulation functions of the main program have problems.
As another embodiment, acquiring an execution time for the electronic device to execute the main control program once includes: executing the main control program once through the electronic equipment, and acquiring the instruction execution starting time and the instruction execution ending time of the main control program; and acquiring the execution time of the electronic equipment for executing the primary control program according to the instruction execution starting time and the instruction execution ending time.
Further, the main control program comprises a first instruction and a second instruction for setting an idle communication port of the electronic equipment, and the time for setting the idle communication port to be a first value through the first instruction is obtained to be used as the instruction execution starting time of the main control program; and acquiring the time for setting the idle communication port to be at the second value through the second instruction as the instruction execution end time of the main control program.
That is, in acquiring the execution time, in addition to directly calculating the display time from the image size and the transmission rate and obtaining the execution time from the calculated display time and the execution times of all the instructions other than the display time, the execution time may be acquired by calculating the instruction execution start and end times, i.e., the difference between the instruction execution start and end times.
Specifically, in the process of transmitting the image data to be displayed through the MCU serial port communication by the electronic device, the port of the MCU serial port communication is in a working communication port during data transmission, the port of the non-working communication is an idle communication port, and in the execution process of a main program, the execution time can be obtained according to the running time interval of two idle communication ports.
In a main control program of electronic equipment, a command starting position is correspondingly provided with a first command, a command ending position is correspondingly provided with a second command, the first command or the second command is triggered only when an MCU serial port communication port is an idle communication port, when the port of the MCU serial port communication is in the idle communication port, the first command is triggered, the time point of the triggering of the first command at this time is recorded, the time is taken as the time point of starting the execution of the main control program, in the execution process of the main control program, the port of the MCU serial port communication is always in a working communication port, when the idle communication port of the main control program reappears in the communication process, namely the execution of the main program is finished at this time, the second command is triggered, the time point of the triggering of the second command at this time is recorded, the time is taken as the time point of finishing the execution of the main control program, according to the time point of starting the execution of the program and the time point of finishing the execution of the program, the execution time of the main program can be calculated once.
In the main control program, the execution time may be obtained by counting the time by a timer when the first command corresponding to the start position and the second command corresponding to the end position are triggered. That is to say, a timing program can be set in the main control program, when the port of the MCU serial port communication is in an idle communication port, the first instruction triggers, and at this time, the timer starts to time, and when the idle communication port appears again in the communication process of the main control program, that is, the main program is executed this time, the second instruction triggers, and the timer stops timing, and the recording time of the timer is the execution time of the main program.
Step S102, when the execution time is determined to exceed the preset time threshold, dividing the image to be displayed into a plurality of sub images to be displayed.
Specifically, when the image to be displayed is too large, the data transmission time is prolonged, which results in the image display time plus the execution time of other instructions in the main program being too long, possibly exceeding the preset time threshold of the electronic device, that is, the execution time of the primary main program is greater than the preset time threshold, when the situation occurs, in order to prevent the screen flash of the electronic equipment caused by the overlong transmission time of the picture data and the problems of other circulation functions of the primary program, the image to be displayed is divided into a plurality of sub-images to be displayed, which is equivalent to dividing the image to be displayed with larger data into sub-images to be displayed with smaller data, thereby ensuring that the execution time of a main program of the sub-image to be displayed in the display process is less than the preset time threshold, and then the problem of screen flashing possibly occurring on the display screen and the problem that other circulation functions of the main program are occupied are solved.
In some embodiments, dividing the image to be displayed into a plurality of sub-images to be displayed comprises: acquiring the ratio of the execution time to a preset time threshold; and acquiring the number of the sub-images to be displayed according to the ratio.
Specifically, when it is determined that the execution time of the primary program is too large, that is, the execution time of the primary program exceeds the preset time threshold of the electronic device, rounding needs to be performed according to the ratio of the execution time of the primary program to the preset time threshold to calculate the number N of the sub-images to be displayed.
It should be noted that, after the sub-images to be displayed are divided, the execution time of the primary main program of the sub-images to be displayed each time is the ratio of the execution time of the primary main program of the original image to be displayed to the number N of the sub-images to be displayed, so that the execution time of the main program is greatly reduced, the execution time of the primary main program of the sub-images to be displayed after the sub-images are subjected to screen division processing is ensured to be less than a preset time threshold, meanwhile, the data volume required to be transmitted when the original image to be displayed is also averagely divided into N parts, and the data transmission volume of the sub-images to be displayed is reduced.
And step S103, executing the main control program for multiple times through the electronic equipment so as to sequentially display the multiple sub-images to be displayed on the screen.
Specifically, after dividing an original image to be displayed into N sub images to be displayed, correspondingly, executing a main control program for N times in a circulating manner by the electronic equipment, wherein the execution time of each sub image to be displayed when executing the main control program is one N times of the execution time of the original image to be displayed, and meanwhile, the N is obtained by rounding up the execution time of the original image to be displayed and a preset time threshold value, so that the execution time of the sub images to be displayed is completely ensured to be less than or equal to the preset time threshold value; and when the main control program of the sub-image to be displayed is executed circularly each time, the divided data of the sub-image to be displayed is sequentially transmitted to the screen of the electronic equipment, the data transmission quantity of the sub-image to be displayed is also one N times of the data transmission quantity of the original image to be displayed, and finally, the whole original image to be displayed is loaded under the condition that the execution time of the main program when the data quantity of the transmitted image is displayed each time is less than the preset time threshold value, so that the flash screen is eliminated, and the running time of the main cycle of image transmission each time is reduced.
Therefore, the overlarge image to be displayed is divided, and the divided sub-images to be displayed are sequentially displayed, so that the screen flashing problem in the picture refreshing process is effectively solved, and meanwhile, the running time of the main cycle in the screen refreshing process is reduced, and the running time of the main cycle is controlled within the maximum allowable time.
In some embodiments, the screen display method of the electronic device further includes: and when the execution time is determined not to exceed the preset time threshold, executing the main control program once through the electronic equipment to display the image to be displayed on the screen.
Specifically, when the image to be displayed is not large, the data transmission time is short, the image display time plus the execution time of other instructions in the main program is short, so that the preset time threshold of the electronic device is not exceeded, that is, the execution time of the main program does not exceed the preset time threshold, the image to be displayed is not required to be divided into a plurality of sub-images to be displayed, but the image to be displayed is directly displayed on the screen of the electronic device through the main control program, and therefore, the adaptive adjustment of the screen display of the electronic device is achieved.
In some embodiments, the screen display method of the electronic device further includes: acquiring hardware parameters of the electronic equipment; and acquiring a preset time threshold according to the hardware parameter, wherein the preset time threshold is the maximum allowable time for the electronic equipment to execute the primary main control program.
Specifically, by acquiring parameters of hardware such as a processor and a memory of the electronic device, and according to parameters such as the maximum operational performance of the processor of the electronic device and the maximum storage capacity of the memory, a preset time threshold value in the process of displaying an image on a screen of the electronic device is acquired, the preset time threshold is the maximum allowable time of the main cycle running time, and in the process of displaying the image to be displayed, ensuring that the execution time does not exceed the maximum allowable time of the main loop running time, if the maximum allowable time of the main loop control program running time is exceeded, dividing the image to be displayed after rounding the execution time of the primary program and the ratio of the preset time threshold value as described above, sequentially transmitting and displaying the divided sub-images to be displayed, therefore, the execution time of the sub-image to be displayed does not exceed the maximum allowable time of the main cycle running time, and the aims of eliminating the splash screen and reducing the main cycle running time of each image transmission are fulfilled.
Further, as a specific example, referring to fig. 2, the screen display method of the electronic device may include the steps of:
step S201, obtaining the execution time T of the original image to be displayed of the electronic equipmentoldAnd a preset time threshold Tmax。
Specifically, it is possible to directly calculate the display time from the size of the image to be displayed and the transmission rate, and to calculate the display time from the calculated display time and the display time other than the display timeThe execution time of all the instructions of the system obtains the execution time T of the original image to be displayedoldOr obtaining the execution time T of the original image to be displayed through the running time interval of two idle communication ports for instructing the execution start and the execution endold(ii) a And acquiring a preset time threshold T in the process of displaying the image on the screen of the electronic equipment according to the parameters of hardware such as a processor, a memory and the like of the electronic equipmentmax。
Step S202, judging ToldWhether or not greater than Tmax. If so, step S204 is executed, otherwise, step S203 is executed.
Specifically, the execution time T of the image to be displayed is judgedoldAnd a preset time threshold TmaxIf the time T is executedoldGreater than a preset time threshold TmaxIf the image to be displayed is too large, step S204 is executed, and if the execution time T is up tooldLess than or equal to the preset time threshold TmaxIf the size of the image to be displayed is normal, step S203 is executed.
Step S203, the whole image to be displayed is transmitted to the screen of the electronic equipment, and the program runs normally.
Specifically, the execution time T when the image to be displayed isoldLess than or equal to the preset time threshold TmaxWhen the image to be displayed is displayed on the screen of the electronic equipment directly through a main control program, namely,
step S204, dividing the original image to be displayed into N sub-images to be displayed.
Specifically, the execution time T when the image to be displayed isoldGreater than a preset time threshold TmaxAccording to the execution time T of the image to be displayedoldAnd a preset time threshold TmaxThe ratio is rounded to calculate the number N of the subimages to be displayed, when the ratio is not an integer, the ratio is rounded to serve as the number N of the subimages to be displayed, the original image to be displayed is divided into N subimages to be displayed, after the subimages to be displayed are divided, the execution time of the primary program of the subimages to be displayed each time is the execution time of the primary program of the original image to be displayed and the number N of the subimages to be displayedA ratio.
In step S205, the electronic device executes a main control program to sequentially display the sub-images to be displayed on the screen.
Specifically, after the original image to be displayed is divided into N sub-images to be displayed, correspondingly, the electronic device circularly executes the main control program, and when the main control program is circularly executed each time, the divided data of the sub-images to be displayed are sequentially transmitted to the screen of the electronic device, and the data transmission quantity of each sub-image to be displayed is also averagely divided into N parts, so that the data of each image to be displayed is reduced.
In step S206, it is determined whether to execute the main program loop N times. If yes, step S207 is executed, otherwise, step S205 is returned to.
Specifically, when the data of the sub-images to be displayed are sequentially transmitted to the screen of the electronic device, the number of the displayed sub-images to be displayed needs to be recorded, if the number of the displayed sub-images to be displayed does not reach N, the step S205 is returned, the non-displayed sub-images to be displayed are continuously and sequentially displayed, and if the number of the displayed sub-images to be displayed reaches N, the batch transmission of the original image data to be displayed is completed, and the step S207 is executed.
In step S207, the picture display is completed, and the program runs normally.
