Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
With the development of display technology, the requirement for display flexibility of the display device is increasing. Currently, a display device can adjust the frame rate of the display device according to the display content. For example, the normal frame rate of a display device (such as a mobile phone) is 60 hz, that is, the display device displays 60 frames per second. When the display screen of the display device does not need to be rapidly switched for display, for example, the display screen is a text document, the frame frequency of the display device can be reduced, so that the electric energy utilization rate is improved. When the display screen of the display device needs to be quickly switched for display, for example, when the display screen is a game screen, the frame frequency of the display device can be increased to improve the display smoothness.
In the related art, when the driving integrated circuit receives a frame rate adjustment instruction in the process of transmitting image data corresponding to a certain frame of image to the display screen according to a first frame rate, the driving integrated circuit immediately executes the frame rate adjustment instruction. In the process of executing the frame frequency adjustment instruction, the driving integrated circuit cannot transmit the residual image data corresponding to the frame image to the display screen according to the first frame frequency, and the transmission time sequence of the residual image data is disordered, so that the display screen cannot normally display the frame image, and abnormal display phenomena such as black screen, flower screen or incomplete image display may occur, and the display effect of the display device is poor.
Fig. 1 is a flowchart of a frame rate adjustment method according to an embodiment of the present application. The method may be used to drive an integrated circuit, as shown in fig. 1, and may include:
step 101, when a frame rate adjustment instruction is received in the process of transmitting image data corresponding to a first image to a display screen according to a first frame rate, transmitting residual image data corresponding to the first image to the display screen according to the first frame rate.
Step 102, after all the image data corresponding to the first image are transmitted to the display screen, the first frame frequency is adjusted to the second frame frequency based on the frame frequency adjustment instruction.
And 103, transmitting image data corresponding to the second image to the display screen according to the second frame frequency.
It should be noted that, in the embodiment of the present application, after the frame rate of the second image is switched to the second frame rate, the driving integrated circuit controls the subsequent image displayed on the display screen.
In summary, in the frame rate adjustment method provided by the present application, the driving integrated circuit may adjust the frame rate of the display device after transmitting all the image data corresponding to the first image to the display screen. Therefore, the driving integrated circuit does not influence the normal display of the first image currently displayed by the display screen when the frame frequency is adjusted, so that the image display smoothness of the display device is higher and the display effect of the display device is better when the frame frequency is adjusted.
Fig. 2 is a flowchart of another frame rate adjustment method according to an embodiment of the present application. The method may be used to drive an integrated circuit, as shown in fig. 2, and may include:
step 201, determining that a frame rate adjustment instruction is received when a change operation for the type of display content is detected in the process of transmitting image data corresponding to a first image to a display screen according to a first frame rate.
In the embodiment of the application, the display device can comprise a display device main board, a driving integrated circuit and a display screen, wherein the driving integrated circuit can acquire image data corresponding to images from the display device main board according to a frame frequency, and further transmit the image data corresponding to the images to the display screen according to the frame frequency, so that the display screen displays the images according to the frame frequency. The driving integrated circuit transmits image data corresponding to a certain frame of image to the display screen, namely, the driving integrated circuit controls each pixel in the display screen to emit light according to the image data corresponding to the frame of image, so that the display screen displays the frame of image.
Alternatively, the display device may display different types of content at different frame rates. When the driving integrated circuit detects a change operation for the type of the display content in the process of transmitting the image data corresponding to the first image to the display screen according to the first frame frequency, the driving integrated circuit can determine that the type of the content to be displayed (namely, the subsequent display content) is different from the type of the content currently displayed, and further can determine that the frame frequency adjustment instruction is received.
Alternatively, the change operation for the type of display content may be a trigger instruction for an application in the display device. For example, when the driver integrated circuit receives a running instruction for the game application program triggered by the user through the display screen, the driver integrated circuit may determine that the content to be displayed is a game screen, and then determine that the target type of the content to be displayed is a game type. As another example, when the driving integrated circuit receives an operation instruction for the movie playing application program triggered by the user through the display screen, the driving integrated circuit may determine that the content to be displayed is a movie picture, and further determine that the target type of the content to be displayed is a movie type.
It should be noted that, there are various possible implementations of the driving integrated circuit for determining that the frame rate adjustment command is received, and the following four possible implementations are taken as examples for explaining the embodiment of the present application.
In a first implementation, the driver integrated circuit may determine a target type of the content to be displayed (i.e., a type of the content to be displayed later), and then acquire a second frame rate corresponding to the target type. The driving integrated circuit may determine that a frame rate adjustment instruction is received when the second frame rate is acquired, and the frame rate adjustment instruction may be used to instruct the driving integrated circuit to adjust the first frame rate to the second frame rate.
The driving integrated circuit may determine the second frame rate in a variety of ways. Alternatively, a correspondence between the type of the display content and the frame rate of the display device may be stored in the display device, and the driving integrated circuit may determine the second frame rate corresponding to the target type of the display device according to the correspondence. The frame rate for the game type is 120 hz, and the frame rate for the movie type is 60 hz, for example. The driving integrated circuit may also obtain the second frame rate corresponding to the target type of the display content from other storage devices through the network, or the driving integrated circuit may also determine the second frame rate through other manners, which is not limited in the embodiment of the present application.
In a second implementation manner, the driving integrated circuit may control the display screen to display a prompt interface for prompting whether to perform frame rate adjustment when detecting a change operation for the type of the display content. When the driving integrated circuit detects a trigger operation for the prompt interface, it may be determined that a frame rate adjustment instruction is received.
It should be noted that, in the embodiment of the present application, before the frame frequency adjustment is performed, a prompt interface may be displayed, so that whether the frame frequency adjustment is performed or not is selected by the user, so that the frame frequency adjustment better meets the requirements of the user, and user experience is improved.
Other implementations in which the driving integrated circuit determines that the frame rate adjustment command is received may be obtained in combination with the first and second implementations described above, for example, the third and fourth implementations described below may be obtained.
In a third implementation manner, the driving integrated circuit may determine a target type of the content to be displayed and acquire a second frame rate corresponding to the target type when detecting a change operation for the type of the display content. The driving integrated circuit can control the display screen to display a prompt interface for prompting whether to adjust the frame frequency to the second frame frequency. When the driving integrated circuit detects a trigger operation for the prompt interface, it may be determined that a frame rate adjustment instruction is received.
In a fourth implementation manner, the driving integrated circuit may control the display screen to display a prompt interface for prompting whether to make a frame rate adjustment when detecting a change operation for a type of display content. When the driving integrated circuit detects triggering operation aiming at the prompt interface, determining a target type of the content to be displayed, and when a second frame frequency corresponding to the target type is acquired, determining that a frame frequency adjustment instruction is received.
Fig. 3 is a schematic diagram of a prompt interface of a display device according to an embodiment of the present application. The prompt interface may be a prompt interface displayed by the driving integrated circuit control display screen in the third implementation manner. As shown in fig. 3, the prompt interface 30 may display prompt information for prompting whether to adjust the frame rate of the display device to a second frame rate corresponding to the target type of the content to be displayed. Assuming that the target type is a movie type and the second frame rate corresponding to the movie type is 60 hz, the prompt information may be "whether to adjust the frame rate to 60 hz to play the movie more smoothly? The prompt interface may further include a "ok" option and a "cancel" option, and when the user clicks the "ok" option, the driver integrated circuit may determine that a trigger operation for the prompt interface is detected, and further determine that a frame rate adjustment instruction is received. When the user clicks the cancel option, the driving integrated circuit may not perform frame frequency adjustment, but still acquire image data corresponding to the subsequent image from the display device motherboard according to the first frame frequency, and transmit the image data corresponding to the subsequent image to the display screen according to the first frame frequency.
And 202, transmitting residual image data corresponding to the first image to a display screen according to a first frame frequency.
When the driving integrated circuit receives the frame frequency adjustment instruction in the process of transmitting the image data corresponding to the first image to the display screen according to the first frame frequency, the driving integrated circuit does not immediately execute the frame frequency adjustment instruction, continuously acquires the residual image data corresponding to the first image from the display device main board according to the first frame frequency, and continuously transmits the residual image data to the display screen according to the first frame frequency.
Optionally, in the process of transmitting the image data corresponding to a certain frame of image to the display screen, the driving integrated circuit may store the image data corresponding to the frame of image and the transmission timing of the image data corresponding to the frame of image in the target storage space. Alternatively, in the process of transmitting the image data corresponding to the next frame image to the display screen by the driving integrated circuit, the image data corresponding to the next frame image and the transmission timing of the image data corresponding to the next frame image may be stored in the target storage space. Alternatively, the image data corresponding to the next frame image and the transmission timing of the image data corresponding to the next frame image may cover the data originally stored in the target storage space.
For example, the driving integrated circuit may store the image data corresponding to the first image and a transmission timing of the image data corresponding to the first image in the target storage space in a process of transmitting the image data corresponding to the first image to the display screen at the first frame rate (i.e., when steps 201 and 202 are performed).
And 203, after all the image data corresponding to the first image are transmitted to the display screen, stopping obtaining the image data corresponding to the next frame of image, and adjusting the first frame frequency to the second frame frequency based on the frame frequency adjusting instruction. .
Optionally, after the driving integrated circuit receives the frame rate adjustment instruction in the process of transmitting the image data corresponding to the first image to the display screen, all the image data corresponding to the first image may be transmitted to the display screen, and then the acquisition of the image data corresponding to the next frame of image is stopped, and the frame rate adjustment instruction is executed to adjust the frame rate of the display device. Therefore, the phenomenon that the display equipment is stained due to the fact that the driving integrated circuit cannot orderly acquire image data corresponding to each frame of image according to a certain frame frequency in the frame frequency adjustment process and transmits the image data corresponding to each frame of image to the display screen, and the transmission time sequence of the image data corresponding to the image is disordered can be avoided.
Alternatively, the driving integrated circuit may start adjusting the frame rate of the display device within a frame interval period after all the image data corresponding to the first image is transmitted to the display screen. Because the time length required by the frame frequency adjustment process cannot be determined, the frame frequency can be immediately adjusted after all image data corresponding to the first image are transmitted, and further the frame frequency adjustment is completed as soon as possible on the basis that the normal display of the first image is not affected, and the frame frequency adjustment efficiency is improved.
Optionally, the driving integrated circuit may also transmit the image data corresponding to at least one frame of image after transmitting all the image data corresponding to the first image to the display screen, and start adjusting the frame rate of the display device in a frame interval period after all the image data corresponding to the at least one frame of image is transmitted.
Optionally, in the process of adjusting the first frame frequency to the second frame frequency based on the frame frequency adjustment command, the driving integrated circuit needs to acquire a frame frequency adjustment code corresponding to the frame frequency adjustment command first, and then execute the frame frequency adjustment code to adjust the first frame frequency to the second frame frequency. Alternatively, the frame rate adjustment instruction may indicate a memory address of the frame rate adjustment code from which the drive integrated circuit may acquire the frame rate adjustment code.
Optionally, in the process of adjusting the first frame rate to the second frame rate, the driving integrated circuit may transmit the image data corresponding to the first image stored in the target storage space to the display screen according to the transmission timing sequence of the image data corresponding to the first image stored in the target storage space, which is equivalent to that the driving integrated circuit transmits the image data corresponding to the first image to the display screen again according to the first frame rate, and further, the display screen may display the first image again according to the first frame rate.
In the frame frequency adjustment process, the driving integrated circuit outputs image data to the display screen according to the transmission time sequence stored in the target storage space, and the output process is not influenced by the frame frequency adjustment, so that the display screen can still normally display images in the frame frequency adjustment process. And further, the phenomenon of abnormal display such as black screen or flower screen of the display device caused by the fact that the driving integrated circuit cannot acquire and output image data corresponding to each frame of image according to the same frame frequency in the frame frequency adjustment process is avoided, and the picture displayed by the display screen in the frame frequency adjustment process is smoothly transited.
And 204, transmitting image data corresponding to the second image to the display screen according to the second frame frequency.
After the frame frequency of the display device is switched to the second frame frequency, the driving integrated circuit controls the subsequent image displayed by the display screen. After the driving integrated circuit adjusts the first frame frequency to the second frame frequency and transmits all image data corresponding to the first image stored in the target storage space to the display screen according to the transmission time sequence stored in the target storage space, the driving integrated circuit can acquire the image data corresponding to the second image from the display device main board according to the second frame frequency and transmit the image data corresponding to the second image to the display screen according to the second frame frequency. Therefore, the image displayed by the display screen can be completely displayed in the frame frequency adjusting process, and the display screen can be ensured to smoothly display the subsequent images.
Optionally, after the driving integrated circuit adjusts the first frame rate to the second frame rate and transmits all the image data corresponding to the first image stored in the target storage space to the display screen according to the transmission time sequence stored in the target storage space, a response signal may be sent to the display device motherboard to instruct the display device motherboard to send the image data corresponding to the subsequent image to the driving integrated circuit according to the second frame rate, so that the driving integrated circuit may acquire the image data corresponding to the subsequent image according to the second frame rate.
Fig. 4 is a timing diagram of a frame rate adjustment process according to an embodiment of the present application. Referring to fig. 4, assuming that the first frame rate is 60 hz, that is, the driving integrated circuit transmits image data corresponding to 60 frames of images to the display screen every second, the display screen displays 60 images every second, and the display screen can display a complete image in time A1 to A3. At time A2, the user triggers the display device to run the game application program, at this time, the driving integrated circuit may determine that the type of the content to be displayed on the display screen is a game type, and determine a second frame frequency corresponding to the game type, so that the driving integrated circuit may determine that a frame frequency adjustment instruction is received, where the frame frequency adjustment instruction is used to instruct the driving integrated circuit to adjust the first frame frequency to the second frame frequency. Such as 120 hz. Optionally, the frame rate adjustment instruction may further indicate a memory address of frame rate adjustment code to be executed to adjust the frame rate to 120 hz.
With continued reference to fig. 4, it is assumed that the driving integrated circuit determines that the display screen is currently displaying the (N-1) -th frame image when the frame rate adjustment instruction is acquired. After the display of the (N-1) -th frame image at the time A3 is completed, the driving integrated circuit may start to acquire the frame rate adjustment code from the storage address indicated by the frame rate adjustment instruction, and may output the image data corresponding to the (N-1) -th frame image stored in the target storage space to the display screen again, so that the display screen starts to display the nth frame image from the time A4, where the nth frame image is identical to the (N-1) -th frame image. Thus, abnormal display conditions such as black screen or flower screen of the display screen can be avoided when frame frequency adjustment is carried out.
The frame rate adjustment code is typically acquired for a time period shorter than the time period for displaying one frame of image. At time A5 in fig. 4, the driving integrated circuit may complete the acquisition of the frame rate adjustment code, and at this time, the display screen is still displaying the nth frame image, and the driving integrated circuit may wait for the nth frame image to be displayed, and resume the normal acquisition and output of the image data. If the nth frame of image is displayed at the time A6, the driving integrated circuit may determine that the frame rate adjustment code is ready (i.e. the frame rate adjustment instruction is executed) at the time A6, and then acquire the image data corresponding to the subsequent image from the display device motherboard at 120 hz, and control the display screen to display the subsequent image at the frame rate of 120 hz.
In summary, in the frame rate adjustment method provided by the embodiment of the application, the driving integrated circuit may adjust the frame rate of the display device after transmitting all the image data corresponding to the first image to the display screen. Therefore, the driving integrated circuit does not influence the normal display of the first image currently displayed by the display screen when the frame frequency is adjusted, so that the image display smoothness of the display device is higher and the display effect of the display device is better when the frame frequency is adjusted.
