The processing unit 110 may be further configured to respond to the received operation instruction of the user. The processing unit 110 responds to an operation instruction of the user, which means that the processing unit 110 controls to output response data including picture data, audio data, and the like in accordance with the operation instruction of the user. The embodiment of the present invention mainly aims at the fact that the processing unit 110 can control the output of the picture data. When the processing unit 110 responds to the operation instruction of the user, that is, the processing unit 110 controls to output corresponding response data, the processing unit 110 is further configured to synchronously generate a clock signal corresponding to the response data. Optionally, the clock signal is represented by a level value, and when the processing unit 110 determines that the next data frame and the previous data frame are the same data frame, the output clock signal corresponding to the next data frame is controlled to be the same as the output clock signal corresponding to the previous data frame, that is, the level values of the two clock signals are the same; when the processing unit 110 determines that the next data frame and the previous data frame are different data frames, the level value of the clock signal corresponding to the next data frame and the level value of the clock signal corresponding to the previous data frame that are controlled to be output are different, that is, a rising edge or a falling edge will be generated. When the processing unit 110 controls to output corresponding response data, and sends the response data to the driving unit 120, optionally, the response data is output externally by means of a digital signal.

In the embodiment of the present invention, the processing unit 110 may be a CPU in the electronic device, the driving unit 120 may be an IC in the electronic device, the Driver IC is configured to control a display state of a display screen in the electronic device according to the refresh frequency, and the display unit may be the display screen in the electronic device.
Based on the electronic device shown in fig. 1, an embodiment of the invention provides a display method of an electronic device. As shown in fig. 2, the method includes:
in this step, for a history period whose time length is set from the current time, the fluctuation state of the clock signal in the period may be acquired by the identification unit in the electronic device. The clock signal is generated by a processing unit in the electronic device and sent to a driving unit in the electronic device, further, if the processing unit determines that the generated next data frame and the generated previous data frame are the same data frame, the processing unit will generate the same clock signal, that is, the level values respectively corresponding to the adjacent data frames are the same, and if the processing unit determines that the generated next data frame and the generated previous data frame are different data frames, the processing unit will generate different clock signals, that is, the level values respectively corresponding to the adjacent data frames are different, in other words, a rising edge or a falling edge will be generated at this time.
In this step, when the identification unit obtains the fluctuation state of the clock signal within the historical period of the set time length from the current time, the identification unit may further determine the current display state of the display unit in the electronic device, where the display state is used to determine the refresh frequency of the display unit by the driving unit, so that the driving unit may control the display state of the display unit according to the determined screen refreshing frequency, so that the picture data is displayed on the display unit at the appropriate refresh frequency.
Based on the scheme, the identification unit in the electronic device acquires the fluctuation state of the clock signal in the preset time period and determines the current display state of the display unit in the electronic device based on the fluctuation state, so that the refresh frequency of the display unit by the driving unit in the electronic device can be determined based on the current display state, the frequency of the display unit in the process of displaying the picture data can be dynamically adjusted, and unreasonable power consumption in the display process can be reduced.
The above steps will be described in detail with reference to examples.
In one implementation of step 201, the preset time period is a history time period with a set time length closest to the current time. By taking the history time period with the time length closest to the current time as the preset time period, the fluctuation state of the clock signal acquired by the identification unit can better represent the state of the processing unit at the current time when the processing unit outputs the picture data according to the preset time period.
In one implementation of step 202 above, if the fluctuation state of the clock signal in the preset period refers to whether there is a change of the clock signal in the preset period, there will be two possibilities:
one possible implementation is: the identification unit determines that the clock signal of the next data frame is different from the clock signal of the previous data frame in the preset time period, namely a rising edge or a falling edge is generated, and after the rising edge or the falling edge is generated, the level value corresponding to the clock signal shows high-low variation, and then the identification unit determines that the display state of the display unit at the current moment is dynamic display. If the driving unit controls the image data to be displayed on the display unit at a higher refreshing frequency, the identification unit does not need to adjust the refreshing frequency; if the driving unit controls the image data to be displayed on the display unit at a lower refreshing frequency, the identification unit needs to adjust the refreshing frequency, so that the driving unit improves the fluency of the control image data when the control image data is displayed on the display unit according to the adjusted refreshing frequency, and the feeling effect of a user on the image display is enhanced.
For example, in a possible scenario, for a user to start a video playing software on an electronic device and continue to click a series of operation instructions of one of video files (the video file can be normally played after being clicked), response data of a processing unit in the electronic device to the operation instructions of the user will be data frames that continuously generate one frame, where two adjacent data frames are not completely the same, so that the processing unit will also correspondingly generate clock signals corresponding to the data frames, and level values corresponding to the clock signals show high-low variation, as shown in fig. 3, which is a schematic diagram for dynamically displaying corresponding clock signals provided by an embodiment of the present invention; therefore, when the driving unit receives the data frames, the next data frame is used for replacing the previous data frame temporarily stored in the GRAM when the next data frame is determined to be different from the previous data frame by comparing the two adjacent data frames, the data format of the data frame stored in the GRAM is converted, the data frame is converted into an analog signal which can be displayed on the display unit and is sent to the display unit, and the display unit displays the picture data. When the display unit displays the picture data, the display unit displays the picture data at the refresh frequency controlled by the driving unit, and the driving unit displays the picture data on the display unit by receiving the refresh frequency determined by the processing unit. The refresh rate at this time is higher, for example, a default screen refresh rate may be used.
One possible implementation is: the identification unit determines that the clock signal of the next data frame is the same as the clock signal of the previous data frame in the preset time period, that is, the level value corresponding to the clock signal is maintained at a fixed level value (the level value corresponding to the rising edge or the level value corresponding to the falling edge) in the preset time period, and then the identification unit determines that the display state of the display unit at the current time is static display. If the driving unit controls the picture data to be displayed on the display unit at a higher refreshing frequency, the identification unit needs to adjust the refreshing frequency, so that the driving unit controls the picture data to be displayed on the display unit according to the adjusted refreshing frequency, and the aim of reducing unreasonable power consumption in the display process on the premise of not influencing visual effect is fulfilled; if the driving unit controls the frame data to be displayed on the display unit at a lower refresh frequency, the identification unit does not need to adjust the refresh frequency.
For example, in a possible scenario, when a user clicks on album software on an electronic device, after the user slides a plurality of photos and determines a target photo, the user has no operation instruction on the electronic device, that is, the user is watching the target photo. For the process that the user determines the target photo and does not make any operation instruction to the electronic device any more, the processing unit in the electronic device will also respond to the process, and the response data is a data frame that continuously generates one frame, wherein two adjacent data frames are identical and both correspond to the data frame where the target photo is located, so that the processing unit will also generate the clock signal corresponding to the data frames, and the clock signal will be maintained at a fixed level value (a level value corresponding to a rising edge or a level value corresponding to a falling edge), as shown in fig. 4(a) and fig. 4(b), corresponding clock signal diagrams are respectively provided for the static display based on the rising edge and the static display based on the falling edge according to the embodiment of the present invention. Therefore, when the driving unit receives the data frames, the next data frame is determined to be the same as the previous data frame by comparing the two adjacent data frames, the next data frame does not need to replace the previous data frame temporarily stored in the GRAM, the data frame stored in the GRAM only needs to be converted into a data format, the data format is converted into an analog signal which can be displayed on the display unit, the analog signal is sent to the display unit, and the display unit displays the picture data. When the display unit displays the picture data, the display unit displays the picture data at the refresh frequency controlled by the driving unit, and the driving unit displays the picture data on the display unit by receiving the refresh frequency determined by the processing unit. The refresh frequency at this time is low, and for example, the refresh frequency at this time may be adjusted to a value slightly smaller than the default screen refresh frequency.
In one implementation of step 202 above, if the fluctuation state of the clock signal in the preset period refers to the number of times the clock signal changes in the preset period, then:
if the number of times of the change of the clock signal in the preset time period is higher, the identification unit can control the refresh frequency to be higher; if the number of times of the change of the clock signal in the preset time period is low, the identification unit may control the refresh frequency to be lower.
For example, as shown in fig. 5(a) and fig. 5(b), schematic diagrams of clock signals for high frequency change and low frequency change are provided according to an embodiment of the present invention. As can be seen by comparing fig. 5(a) and 5(b), the change of the clock signal is generated 8 times in fig. 5(a), and only 2 times in fig. 5(b) within the same preset period S. Based on this, in order to realize the screen display effect adapted to the frequency of the clock signal change, the identification unit may control the refresh frequency to be higher when the clock signal changes more frequently, and control the refresh frequency to be slightly lower when the clock signal changes less frequently, so that the display process of the picture data on the display unit may be dynamically adjusted.
In one implementation of step 202, if the identification unit in the electronic device is a processing unit in the electronic device, it indicates that the processing unit obtains a fluctuation state of the clock signal in a preset time period, and after determining that the display unit is in the current display state, the processing unit directly determines a refresh frequency corresponding to the display unit according to the current display state of the display unit, and sends the determined refresh frequency to the driving unit, so that the driving unit can display the picture data on the display unit according to the refresh frequency.
In one implementation of step 202, if the driving unit in the electronic device is the driving unit in the electronic device, it indicates that the driving unit acquires a fluctuation state of the clock signal within a preset time period, and after determining that the display unit is in the current display state, the driving unit feeds back the determined display state to the processing unit in the electronic device, and after determining that the display state actually corresponds to the refresh frequency, the processing unit gives the determined refresh frequency to the driving unit, so that the driving unit can display the picture data on the display unit according to the refresh frequency.
Based on the same concept, an embodiment of the present invention provides an electronic device, which may refer to the electronic device in fig. 1, including an identification unit 100, a processing unit 110, a driving unit 120, and a display unit 130; wherein:
the identification unit is used for acquiring the fluctuation state of the clock signal in a preset time period, wherein the preset time period is a historical time period with a set time length away from the current time; the clock signal is generated by the processing unit and sent to the driving unit, the processing unit is used for determining whether the generated adjacent data frames are the same data frame or not, and generating the same clock signal when the generated adjacent data frames are determined to be the same data frame, otherwise, generating different clock signals; the identification unit is further used for determining the current display state of the display unit based on the fluctuation state of the clock signal in a preset time period;
