Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The embodiment of the application provides a method and a device for adjusting a display panel, a storage medium and computer equipment. Specifically, the adjusting method of the display panel according to the embodiment of the present application may be executed by a terminal. The terminal can be a terminal device such as a smart phone, a tablet Computer, a notebook Computer, a touch screen, a Personal Computer (PC), a Personal Digital Assistant (PDA), and the like.
For example, the terminal may receive a display adjustment instruction for a display panel in the terminal, the display adjustment instruction being used to instruct to adjust a current refresh rate of the display panel to a target refresh rate; determining an adjustment duration required for adjusting the current refresh rate to a target refresh rate; and based on the adjusting duration, the current frame is displayed, and the operation of adjusting the current refresh rate to the target refresh rate is executed through the background of the terminal.
Based on the above problems, embodiments of the present application provide a method and an apparatus for adjusting a display panel, a storage medium, and a terminal, which can improve user experience. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an adjusting method of a display panel according to an embodiment of the present disclosure. Taking the example that the adjusting method of the display panel is applied to the terminal, the specific flow of the adjusting method of the display panel can be as follows:
101. and receiving a display adjusting instruction aiming at a display panel in the terminal.
In the embodiment of the application, the terminal can support different refresh rates, and different refresh rates can be set according to different application scenes. The refresh rate is the number of times the electron beam is repeatedly scanned over the image on the screen, and the higher the refresh rate, the better the stability of the displayed image (picture). For example, the refresh rate may be: 30FPS (Frames Per Second), or 60FPS, etc.
The display adjusting instruction is used for indicating that the current refresh rate of the terminal display panel is adjusted to be the target refresh rate. The current refresh rate is a different refresh rate than the target refresh rate, for example, the current refresh rate may be greater than the target refresh rate, or the current refresh rate may be less than the target refresh rate.
Specifically, the display adjustment instruction may be further triggered by the user operating the terminal, for example, the user operating the terminal may be a display mode switching operation, and under different display modes, refresh rates of display panels of the terminal may be different, so that the display adjustment instruction may be triggered.
102. An adjustment duration required to adjust the current refresh rate to the target refresh rate is determined.
The adjustment duration refers to the time required by the terminal to adjust the refresh rate of the display panel. For example, the adjustment duration may be: 2 seconds, etc.
In this embodiment of the present application, the adjustment duration required for adjusting different refresh rates may be preset, for example, the refresh rate supported by the display panel of the terminal may include: the first refresh rate, the second refresh rate, the third refresh rate, and the like, by performing an adjustment experiment between different refresh rates, the adjustment duration required to adjust the first refresh rate to the second refresh rate may be: 1 second; the adjustment duration required to adjust the first refresh rate to the third refresh rate may be: 1.5 seconds; the adjustment duration required to adjust the second refresh rate to the third refresh rate may be: 2 seconds, etc.
For example, if the current refresh rate may be a first refresh rate and the target refresh rate may be a second refresh rate, then it may be determined that the adjustment duration may be: for 1 second.
In some embodiments, in order to ensure normal display of the display panel, before the step "by displaying the current picture frame based on the adjusted duration", the following steps may be further included:
determining a display picture frame positioned behind a current picture frame from a plurality of display picture frames to obtain a target picture frame;
and performing frame extraction processing on the target picture frame to execute the step of displaying the current picture frame based on the adjusted time length.
In this embodiment, the content displayed on the display panel of the terminal may correspond to a plurality of picture frames, and the plurality of picture frames are sequentially displayed on the display panel according to the display order based on the current refresh rate.
Furthermore, in order to increase the refresh time of the current frame, frame extraction may be performed on one or more frames of the display frame after the current frame, so as to ensure that the refresh time of the current frame is not less than the adjustment time, thereby implementing display of the current frame through the display panel based on the adjustment time length, and simultaneously performing an operation of adjusting the current refresh rate to the target refresh rate through the background of the terminal within the adjustment time.
Where the refresh time is VBlank (vertical blank), a line-by-line scan of a ray of the display starts from the top left, and at the bottom, it returns to the top, and the time it takes is called VBlank because the scan line becomes blank to prevent a diagonal line from being shown on the screen.
In some embodiments, in order to satisfy the requirement of extending the display time of the current picture frame to be not small and the adjustment time, the step "determining a display picture frame located after the current picture frame from a plurality of display picture frames to obtain the target picture frame" may include the following operations:
determining at least one candidate picture frame located after the current picture frame from the plurality of display picture frames;
obtaining the refreshing time length of the candidate picture frame;
a target picture frame is determined from the candidate picture frames based on the adjustment duration and the refresh duration of the candidate picture frames.
Wherein the candidate picture frame refers to a display picture frame whose display order is subsequent to the current picture frame among the plurality of display picture frames. For example, the plurality of display frame may include: a first picture frame, a second picture frame, a third picture frame, a fourth picture frame, and an nth picture frame, wherein a display order of the plurality of display picture frames may be: a first picture frame, a second picture frame, a third picture frame, a fourth picture frame.
For example, the current picture frame may be: the fourth frame, selecting a candidate frame from the plurality of display frames, the candidate frame having a display sequence following the current frame, that is, the fourth frame, includes: a fifth picture frame.
In the embodiment of the present application, the refresh time lengths of different frame may be the same or different. For example, the refresh duration of each candidate picture frame is obtained, the refresh duration of the fifth picture frame may be 1 second, the refresh duration of the sixth picture frame may be 1 second, the refresh duration of the seventh picture frame may be 1 second, the refresh duration of the eighth picture frame may be 1.5 seconds.
The target picture frame is selected from the candidate picture frames based on the adjusting time length and the refreshing time lengths of the candidate picture frames, and the candidate picture frames can be sequentially selected according to the display sequence of the candidate picture frames until the refreshing time lengths of all the selected candidate picture frames are accumulated to reach the adjusting time length.
For example, the adjustment duration may be: and 3 seconds, sequentially selecting the target picture frame from the candidate picture frames comprises: a sixth picture frame, a seventh picture frame, and an eighth picture frame.
103. And based on the adjusting duration, the current frame is displayed, and the operation of adjusting the current refresh rate to the target refresh rate is executed through the background of the terminal.
Wherein the adjustment duration is reached by the time to display the current picture frame, i.e., to continuously display the current picture frame, based on the adjustment duration. When the display panel displays the current picture frame, the background adjusts the refresh rate of the display panel, so that the display of the display panel is ensured to be normal when the refresh rate of the display panel is adjusted.
In some embodiments, in order to improve the accuracy of the refresh rate adjustment, the step "performing, by the background of the terminal, an operation of adjusting the current refresh rate to the target refresh rate" may include the following operations:
acquiring a first parameter value of a frame rate adjusting parameter corresponding to the current refresh rate and a second parameter value of the frame rate adjusting parameter corresponding to the target refresh rate;
and within the adjusting time length, adjusting the first parameter value of the frame rate adjusting parameter to be a second parameter value through the background.
The frame rate adjustment parameter is used to control a refresh rate of the display panel, and specifically, different parameter values are set for the frame rate adjustment parameter to adjust different refresh rates of the display panel. The frame rate adjustment parameter may be stored in a register corresponding to level shift. level shift is level shift. Generally, when two devices need to communicate but their voltage specifications are different, they cannot be directly connected, and level shift is needed for level shift.
For example, the current refresh rate may be: 30FPS, the target refresh rate may be: the first parameter value of the frame rate adjustment parameter corresponding to 60FPS and 30FPS may be: 101, 60FPS may have the first parameter value of the frame rate adjustment parameter as follows: and 111, when the refresh rate is adjusted, the parameter value of the frame rate adjustment parameter in the register which can be adjusted within the adjustment time length is modified from 101 to 111, so that the adjustment of the refresh rate of the display panel can be completed.
In some embodiments, in order to ensure the integrity of the display frame, after the step "determining the adjustment duration required to adjust the current refresh rate to the target refresh rate", the following steps may be further included:
obtaining a refreshing time length corresponding to a current picture frame;
and if the refreshing time length corresponding to the current picture frame is not less than the adjusting time length, displaying the current picture frame through the display panel based on the refreshing time length corresponding to the current picture frame, and performing the operation of adjusting the current refreshing rate to the target refreshing rate through the background.
For example, the refresh duration corresponding to the current picture frame may be obtained as follows: 2 seconds, the adjustment time period may be: 1.5 seconds, it can be determined that the refresh duration corresponding to the current picture frame is greater than the adjustment duration, and at this time, the refresh duration corresponding to the current picture frame satisfies the adjustment duration for the background to adjust the refresh rate of the display panel, so that the frame-extracting step is not required, the current picture frame is directly displayed on the display panel based on the refresh duration corresponding to the current picture frame, and the operation of adjusting the current refresh rate to the target refresh rate is performed through the background.
In some embodiments, to ensure the integrity of the display frame, the method may further comprise the steps of:
if the refreshing time length corresponding to the current picture frame is less than the adjusting time length, determining at least one candidate picture frame positioned behind the current picture frame from the plurality of picture frames;
obtaining the refreshing time length of the candidate picture frame;
and if the refresh duration of the candidate picture frame is not less than the adjusting duration, displaying the current picture frame through the display panel based on the refresh duration corresponding to the candidate picture frame, and performing the operation of adjusting the current refresh rate to the target refresh rate through the background.
For example, the refresh duration corresponding to the current picture frame may be obtained as follows: 1.5 seconds, the adjustment duration may be: and 2 seconds, determining that the refreshing time duration corresponding to the current picture frame is less than the adjusting time duration, namely that the refreshing time duration corresponding to the current picture frame does not meet the adjusting time duration for adjusting the refreshing rate of the display panel by the background.
Further, in order to ensure the integrity of the display frame, the refresh duration corresponding to a specified number of candidate frame frames may be obtained from the candidate frame frames that are sequentially located after the current frame in the display sequence of the plurality of display frame frames, and then it is determined whether the refresh duration having the adjusted duration is satisfied in the refresh durations corresponding to the specified number of candidate frame frames.
For example, the specified number may be: among the plurality of display picture frames, a specified number of candidate picture frames that are located after the current picture frame in display order may be: a seventh picture frame, an eighth picture frame, a ninth picture frame, a tenth picture frame, and an eleventh picture frame. The refresh duration corresponding to the seventh picture frame may be: 1.5 seconds, the refresh duration corresponding to the eighth frame may be: 1.5 seconds, the refresh duration corresponding to the ninth picture frame may be: 1.5 seconds, the refresh duration corresponding to the tenth picture frame may be: 2.4 seconds, the refresh duration corresponding to the eleventh picture frame may be: 1.5 seconds.
Further, comparing the refresh duration of the candidate picture frame with the adjustment duration, it may be determined that the candidate picture frame satisfying the adjustment duration may be: a tenth picture frame. At this time, the refresh duration corresponding to the tenth frame meets the adjustment duration for adjusting the refresh rate of the display panel by the background, so that the frame extraction step is not required, the current frame is directly displayed on the display panel based on the refresh duration corresponding to the tenth frame, and the operation of adjusting the current refresh rate to the target refresh rate is performed by the background.
In some embodiments, to improve refresh rate adjustment efficiency, the method may further comprise the steps of:
and if the refresh duration of the candidate frame is less than the adjusting duration, executing the step of adjusting the current refresh rate to the target refresh rate by displaying the current frame based on the adjusting duration and executing the operation of adjusting the current refresh rate to the target refresh rate through a background of the terminal.
In the embodiment of the present application, if the refresh time of the current frame does not satisfy the adjustment time, and the refresh times of the selected candidate frames in the designated number do not satisfy the adjustment time, in order to complete the adjustment of the refresh rate of the display panel as soon as possible, the display time of the current frame may be increased by the above frame extraction manner, so as to complete the adjustment of the display frame rate of the display panel.
The embodiment of the application discloses a method for adjusting a display panel, which comprises the following steps: receiving a display adjusting instruction aiming at a display panel in the terminal, wherein the display adjusting instruction is used for indicating that the current refresh rate of the display panel is adjusted to be a target refresh rate; determining an adjustment duration required for adjusting the current refresh rate to a target refresh rate; and based on the adjusting duration, the current frame is displayed, and the operation of adjusting the current refresh rate to the target refresh rate is executed through the background of the terminal. When a refresh rate adjusting instruction for a display panel of a terminal is received, frame extraction processing is carried out on a picture frame after a current picture frame to increase the refresh duration of the current picture frame, the refresh duration of the current picture frame is ensured to meet the adjusting duration for executing the refresh rate adjusting operation, then the current picture frame is displayed through the display panel of the terminal to reach the adjusting duration, meanwhile, the refresh rate adjusting operation is carried out through a background of the terminal, normal display of the display panel during refresh rate adjusting can be ensured, and therefore user experience is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart of another adjusting method for a display panel according to an embodiment of the present disclosure. Take the example that the adjusting method of the display panel is applied to the television equipment. The adjusting method of the display panel may specifically be as follows:
201. the television equipment receives a display mode switching instruction of a display panel of the television equipment from a user.
In the embodiment of the present application, the display modes of the display panel at least include a normal display mode and a game mode, and the refresh rates of the display panel in the different display modes are different. For example, in the normal display mode, the refresh rate of the display panel may be: 30 FPS; in the game mode, the refresh rate of the display panel may be: 60FPS, etc.
The display mode switching instruction may refer to switching a conventional display mode of a current display panel to a game mode, the display mode switching instruction may be triggered by a user operating the display panel, and the operating modes may include multiple modes, for example, the operating modes may be controlled by a remote control device, or when the television device supports touch operation, the operating modes may be controlled by touch operation of the display panel of the television device.
202. The television equipment acquires the display mode adjustment duration.
The display mode adjustment duration refers to time required for executing display mode switching according to the display mode switching instruction, that is, time required for switching the conventional display mode to the game mode in the display mode switching instruction. For example, the display mode adjustment period may be 3 seconds or the like.
203. The television equipment determines candidate picture frames from the plurality of picture frames according to the display mode adjusting duration and performs frame extraction processing on the candidate picture frames.
For example, please refer to fig. 3, and fig. 3 is a schematic view illustrating an application scenario of a method for adjusting a display panel according to an embodiment of the present application. When displaying the frame n, the display mode is switched, the frame of the display frame n +1 can be extracted, then the vertical blank time of the right image in fig. 5 can be equal to the vertical blank time of the left display frame n and the display frame n +1 in fig. 5 plus the display time of the display frame n +1, that is, the time can be prolonged to meet the switching of the display mode. Then the level shift register is reset. GOA signal adjustment (e.g., l Line changed to 2Line) by SOC/T-CON IC (timing control circuit).
204. The television equipment maintains that the display duration of the current picture frame of the display panel on the display panel reaches the display mode adjusting duration, and executes the display mode switching operation corresponding to the display mode switching instruction through the background.
Specifically, after the candidate frame after the current frame is subjected to frame extraction processing, the vertical blank time of the current frame is prolonged, so that the current frame can be displayed on the display panel for a longer time, and when the current frame is displayed on the display panel, the background is ensured to finish the display mode switching operation corresponding to the display mode switching instruction, that is, the refresh rate of the display panel is adjusted, so that the conventional display mode is switched to the game mode. For a user, the picture display is normal, and the 'black screen' display cannot occur, so that the user experience is improved.
In some embodiments, the switching time of the levelshift register is set to T, and T is generally less than the V-Blank time at a low frame rate (e.g., 30-60 FPS). If the game mode is switched during the xth frame (display frame x), at this time, the SOC \ T-CON IC detects the frame rate, detects whether the time of the V-Blank is greater than the time T (the V-Blank time can be detected by using the frame buffer), and switches when the time of the V-Blank is detected to meet the requirement.
For example, referring to fig. 4, fig. 4 is a schematic view of an application scenario of another display panel adjustment method according to an embodiment of the present application. If the frame x is displayed and switched, the V-Blank time detection can be carried out on the picture of the display frame x +100 frames (the frame number required to be detected can be set by self), and if the V-Blank time detected in the first display frame x + n (n <100) frames is more than the time T required by switching, the switching is carried out on the picture of the frame. Then the level shift register is reset. GOA signal adjustment (e.g., l Line changed to 2Line) by SOC/T-CON IC (timing control circuit). If no V-Blank time meeting the requirement exists in 100 frames, the mode switching of the black screen or the frame extraction mode is carried out. The mode does not perform frame extraction, the picture display is normal, and the real seamless switching can be realized.
The embodiment of the application discloses a method for adjusting a display panel, the scheme includes that a display mode switching instruction of a user to the display panel of television equipment is received through the television equipment, display mode adjusting time length is obtained, candidate picture frames are determined from a plurality of picture frames according to the display mode adjusting time length, frame extraction processing is carried out on the candidate picture frames, the display time length of the current picture frame of the display panel on the display panel is maintained to reach the display mode adjusting time length, and display mode switching operation corresponding to the display mode switching instruction is executed through a background. Therefore, the refresh rate switching effect of the display panel can be improved.

The terms are the same as those in the above-mentioned adjustment method of the display panel, and the details of the implementation can be referred to the description in the method embodiment.
