The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In order to facilitate understanding of the embodiments of the present application, the following description is made for the display screen:

first, the structure of the display screen is described, and the display screen can be an OLED display screen or an LCD display screen. Fig. 1 shows a schematic structural diagram of a display screen, as shown in fig. 1, the display screen includes m × n sub-pixel units 10, a scan driving chip 20, m scan lines 30, a data driving chip 40, and n data lines 50, where m and n are positive integers.

The m × n sub-pixel units are composed of m rows and n columns of sub-pixel units 10, each row of sub-pixel units 10 corresponds to one scanning line 30, each column of sub-pixel units 10 corresponds to one data line 50, the corresponding color of each sub-pixel unit 10 in the same column of sub-pixel units 10 is the same, and the corresponding color of any adjacent three columns of sub-pixel units 10 is red, green and blue. The sub-pixel units 10 arranged in the ith row and the jth column are respectively connected with the ith row scanning line and the jth column data line, i is a positive integer less than or equal to m, and j is a positive integer less than or equal to n. The scan driving chip 20 includes m pins, each of which is electrically connected to one scan line, and the data driving chip 40 has n pins, each of which is electrically connected to one data line.

For example, for an LCD panel, the ith row and jth column sub-pixel units include liquid crystal capacitors 11, storage capacitors 12, Thin Film Transistors (TFTs) 13, and the like. The TFT includes a gate 13a, a first electrode 13b, and a second electrode 13c, the gate 13a of the TFT is electrically connected to the i-th row scanning line, the first electrode 13b is electrically connected to the j-th column data line, the second electrode 13c is electrically connected to one end of the storage capacitor 12, the second electrode 13c is further electrically connected to one end of the liquid crystal capacitor 11, and the other end of the liquid crystal capacitor 11 and the other end of the storage capacitor 12 are grounded.

The picture frame is composed of orderly arranged multiple rows and multiple columns of pixel points. Each pixel point in the picture frame corresponds to three sub-pixel units in the display screen, the pixel point is displayed by utilizing the three sub-pixel units, the three sub-pixel units are respectively red, green and blue, and the three sub-pixel units can be positioned on the same line and adjacent in position.

For the jth row of pixel points in the picture frame, the jth row of pixel points corresponds to three adjacent rows of sub-pixel units in the screen, and are respectively a row of red sub-pixel units, a row of green sub-pixel units and a row of blue sub-pixel units. When the display screen is used for displaying the picture frame, each pixel point included in the jth column is displayed one by one, and the implementation process can be as follows:

for the 1 st row pixel point of the j-th column, the scanning driving chip 20 scans the 1 st row scanning line to open each sub-pixel unit in the 1 st row sub-pixel unit (the opened sub-pixel unit can input the voltage signal transmitted on the data line connected with the opened sub-pixel unit, and similar descriptions are not described one by one elsewhere); the data driving chip 40 determines gray scale data of three color channels according to the pixel value of the pixel point of the row 1, namely, red channel gray scale data, green channel gray scale data and blue channel gray scale data, converts the red channel gray scale data into a corresponding first voltage signal, converts the green channel gray scale data into a corresponding second voltage signal, and converts the blue channel gray scale data into a corresponding third voltage signal; then, a first voltage signal is input to the data line corresponding to the row of red sub-pixel units, a second voltage signal is input to the data line corresponding to the row of green sub-pixel units, a third voltage signal is input to the data line corresponding to the row of blue sub-pixel units, so that the first voltage signal is input to the red sub-pixel unit located in the 1 st row of the row of red sub-pixel units, the second voltage signal is input to the green sub-pixel unit located in the 1 st row of the row of green sub-pixel units, and the third voltage signal is input to the blue sub-pixel unit located in the 1 st row of the row of blue sub-pixel units, thereby realizing the display of the 1 st row pixel point by using the red sub-pixel unit, the green sub-pixel unit and the blue sub-pixel unit located in the 1 st row.

For the 2 nd row pixel point of the j column, the scanning driving chip 20 scans the 2 nd row scanning line to open each sub-pixel unit in the 2 nd row sub-pixel unit; the data driving chip 40 determines gray scale data of three color channels according to the pixel values of the 2 nd row of pixel points, namely red channel gray scale data, green channel gray scale data and blue channel gray scale data, converts the red channel gray scale data into corresponding first voltage signals, converts the green channel gray scale data into corresponding second voltage signals, and converts the blue channel gray scale data into corresponding third voltage signals; then, a first voltage signal is input to the data line corresponding to the row of red sub-pixel units, a second voltage signal is input to the data line corresponding to the row of green sub-pixel units, a third voltage signal is input to the data line corresponding to the row of blue sub-pixel units, so that the first voltage signal is input to the red sub-pixel unit located in the 2 nd row of the row of red sub-pixel units, the second voltage signal is input to the green sub-pixel unit located in the 2 nd row of the row of green sub-pixel units, and the third voltage signal is input to the blue sub-pixel unit located in the 2 nd row of the row of blue sub-pixel units, thereby realizing the display of the 2 nd row pixel point by using the red sub-pixel unit, the green sub-pixel unit and the blue sub-pixel unit located in the 2 nd row.

The display process of other pixels in each row in the jth column is the same as the display process of the pixels in the 1 st row and the pixels in the 2 nd row, and therefore description is not given one by one. The display screen can display each pixel point in one frame of picture frame according to the mode.

For the LCD panel, the data driving chip 40 inputs a voltage signal to the sub-pixel unit 10 through the data line, and substantially inputs the voltage signal to the liquid crystal capacitor in the sub-pixel unit 10. When the voltage value of the voltage signal transmitted by the data line is greater than the voltage value of the voltage signal stored in the liquid crystal capacitor in the sub-pixel unit 10, the data driving chip 40 charges the liquid crystal capacitor in the sub-pixel unit 10 by using the data line; when the voltage of the voltage signal transmitted by the data line is smaller than the voltage value of the voltage signal stored in the liquid crystal capacitor of the sub-pixel unit 10, the liquid crystal capacitor of the sub-pixel unit 10 discharges to realize the input of the voltage signal to the sub-pixel unit 10 through the data line.

The magnitude of the gray scale data is proportional to the magnitude of the voltage value of the corresponding voltage signal, i.e., the larger the gray scale data is, the larger the voltage value of the corresponding voltage signal is, and the smaller the gray scale data is, the smaller the voltage value of the corresponding voltage signal is. Thus, for the heavy-duty picture, because the heavy-duty picture includes a plurality of color blocks and the color difference between adjacent color blocks is large, each row of pixel points may include a large difference between gray scale data of the same color channel between a plurality of adjacent pixel points, which results in a large voltage signal difference between two adjacent voltage values input to the same row of data lines.

When the voltage signals with large voltage difference are inputted to the data line twice, the load of the data line is easily increased. When the load of the data line is too high, the data driving chip 40 utilizes the data line to increase the power consumption of charging the liquid crystal capacitors in the sub-pixel units 10 in other rows, so that the sub-pixel units 10 do not have enough time to complete the charging process, that is, the data driving chip 40 does not have enough time to completely input the voltage signal into the sub-pixel units 10, the brightness of the sub-pixel units 10 is affected, the display effect of the corresponding pixel points of the sub-pixel units 10 is affected, and the blurred area of the image is easy to appear when the heavy-load picture is displayed.

In order to solve the technical problem, according to any of the following embodiments, when a heavy-duty picture is played, the frame rate of the display card is reduced, that is, the number of display frames in a unit time of the display screen is reduced, so as to increase the duration of displaying one picture frame by the display screen, so as to increase the time for inputting the voltage signal to the sub-pixel unit 10 by the data driving chip 40 through the data line 50, so as to completely input the voltage signal into the sub-pixel unit 10, and avoid the occurrence of the blurred image region.

Fig. 2 is a flowchart illustrating a picture frame display method according to an exemplary embodiment. As shown in fig. 2, the picture frame display method may include the following steps.

In step 210, a first frame is obtained, wherein the first frame is a displayed frame or an undisplayed frame.

In step 220, when the first frame is a heavy-load frame, the set frame rate for displaying the first frame is decreased to obtain the target frame rate.

In step 230, a second frame is displayed according to the target frame rate, wherein the second frame is an undisplayed frame.

Wherein, under the condition that the first picture frame is a displayed picture frame, the second picture frame is a picture frame after the first picture frame; when the first frame is an undisplayed frame, the second frame is the first frame.

In summary, in the image frame display method provided in the embodiment of the present disclosure, by detecting whether a first image frame is a heavy-load image, when it is detected that the first image frame is the heavy-load image, a set frame rate for displaying the first image frame is reduced to obtain a target frame rate, and an image frame that is not displayed is displayed according to the target frame rate; the technical problem that a plurality of heavy-load pictures are continuously displayed on a display screen in the related technology, and the blurred images are easy to appear in the areas is solved; the effect of improving the display effect of the replanting picture is achieved.

Fig. 3-1 is a flowchart illustrating a picture frame display method according to another exemplary embodiment. As shown in fig. 3-1, the picture frame display method may include several steps as follows.

In step 310, a first frame is obtained, wherein the first frame is a displayed frame or an undisplayed frame.

The first frame may be a frame currently displayed by the electronic device, or may be a next frame that the electronic device needs to display. For example, the electronic device is playing a video, the electronic device is displaying a video frame a, and a next frame that needs to be displayed is a video frame B, so that the electronic device may determine the video frame a as a first frame to obtain image data of the video frame a, or may determine the video frame B as the first frame to obtain image data of the video frame B.

The image data of the first picture frame comprises pixel values of all pixel points in the first picture frame, and the pixel value of each pixel point is composed of gray scale data of a red channel, gray scale data of a green channel and gray scale data of a blue channel. For example, if a pixel is white, the gray scale data of the pixel corresponding to the red channel is 0, the gray scale data of the pixel corresponding to the green channel is 0, the gray scale data of the pixel corresponding to the color channel is 0, and the pixel value of the pixel can be represented as rgbb (0, 0, 0).

In step 320, gray-scale data input to data lines for displaying the first frame are obtained, wherein the data lines are located in the display screen.

Here, the gray-scale data input to the data lines when displaying the first frame includes: gray scale data of a red channel, gray scale data of a green channel and gray scale data of a blue channel of each pixel point in the first picture frame.

The step can be realized through the following two steps:

step S1, determine a data line for displaying a target row of pixels, where the target row of pixels is a row of pixels in the first frame.

The target row pixel point corresponds to three rows of sub-pixel units in the display screen and comprises a row of red sub-pixel units, a row of green sub-pixel units and a row of blue sub-pixel units. One data line corresponding to the row of red sub-pixel units, one data line corresponding to the row of green sub-pixel units, and one data line corresponding to the row of blue sub-pixel units are data lines for displaying a target row of pixel points.

The implementation of this step can be: determining three adjacent rows of sub-pixel units at corresponding positions of a target row pixel point in a display screen, wherein the three adjacent rows of sub-pixel units are respectively a row of red sub-pixel units, a row of green sub-pixel units and a row of blue sub-pixel units; a first data line electrically connected to each sub-pixel cell in the column of red sub-pixel cells, a second data line electrically connected to each sub-pixel cell in the column of green sub-pixel cells, and a third data line electrically connected to each sub-pixel cell in the column of blue sub-pixel cells are determined.

Step S2, determining the gray scale data of each pixel point input to the data line according to the pixel value of each pixel point included in the target row pixel point, and the color channels corresponding to each gray scale data input to each data line are the same.

The implementation of this step can be: the method comprises the steps of obtaining a pixel value of each pixel point included by a target row of pixel points, determining red channel gray scale data of each pixel point to obtain gray scale data input to a first data line according to each pixel value, determining green channel gray scale data of each pixel point to obtain gray scale data input to a second data line, and determining blue channel gray scale data of each pixel point to obtain gray scale data input to a third data line.

For example, the pixel values of the pixel points in the first 5 th row of the kth column in the first frame are (0,10,20), (0,20,20), (30,40,20), (80,20,80), and (80,20, 20). The 3k column in the display screen is a row of blue sub-pixel units, and the gray scale data input on the 3k column data line (i.e., the data line connected to the 3k column of blue sub-pixel units) in the display screen sequentially are: 20. 20,80, 20, … …, wherein the voltages input to the data lines are the voltage corresponding to the gray-scale data 20, the voltage corresponding to the gray-scale data 80, and the voltage … … corresponding to the gray-scale data 80.

The other rows of pixel points in the first frame except the target row of pixel points may also be processed in the manners shown in steps S1 and S2 to obtain the gray scale data input on each data line corresponding to each row of pixel points in the other rows of pixel points, which is not described herein again.

In step 330, whether the first frame is a heavy-duty frame is detected according to the gray-scale data inputted to each data line.

This step can be achieved by several steps as shown in fig. 3-2:

in step 3301, for each data line, an absolute value of a difference between any two adjacent gray-scale data input to the data line is calculated.

For example, the 3k th row data line is calculated, and the gray scale data input on the 3k th row data line sequentially includes: 20. 20,80, 20, … …. Since the first input of the gray scale data is 20 and the second input of the gray scale data is 20, the absolute value of the difference between the first and second input of the two gray scale data is 0; the third input of the gray scale data is still 20, so the absolute value of the difference between the second and third input of the two gray scale data is 0; the fourth input is 80 gray scale data, so the absolute value of the difference between the third and fourth input two gray scale data is 60, and so on, and this is not listed here.

And 3302, calculating the average value of the absolute values to obtain an average difference corresponding to the data line, and counting the number of nonzero absolute values to obtain the number of voltage changes on the data line.

The electronic equipment inputs gray scale data to one data line, and substantially changes the voltage input to the data line according to the gray scale data; if the absolute value of the difference value between any two adjacent gray scale data input to the data line is 0, it indicates that the voltage input to the data line is not changed, otherwise, it indicates that the voltage input to the data line is changed once. Therefore, the number of changes in the voltage change on the data line is obtained by counting the number of non-zero absolute values in the absolute values calculated in step 3301.

The implementation of this step can be: obtaining gray scale data of a color channel of the j-th row of pixel points, calculating the difference value of the gray scale data of the color channel of the j-th row of pixel points in the ith row and the gray scale data of the color channel of the j-th row of pixel points in the (i + 1) th row, and obtaining a value H by taking the absolute value of the difference value_ijCalculating an average difference value

Statistics H_1j、H_2j、…H_ijNumber of non-zero absolute values.

And K2, counting the number of data lines in the display screen, the average difference value of which exceeds a preset first threshold value and the change times of the input voltage of which exceeds a preset second threshold value, and determining that the first picture frame is a heavy-load picture when the number exceeds a preset third threshold value.

For the LCD, if the average difference value corresponding to a data line exceeds a first threshold value and the number of input voltage changes is higher than a second threshold value, it indicates that the data line has an excessive load in the process of refreshing the voltages of the liquid crystal capacitors for displaying the first frame on the display screen. If the number of the data lines with overlarge loads is more and higher than the third threshold value in the process, the first picture frame is considered as the reloading picture, otherwise, the first picture frame is not considered as the reloading picture.

In most cases, the image data of two frames displayed continuously on the display screen are similar or identical, and there may be only a few pixels with different pixel values. Therefore, when the display screen displays a reloading picture, the next frame or frames displayed by the display screen may be reloading pictures. In case that the first frame is determined to be the reloading frame, step 340 is executed to avoid that the consecutive display of the reloading frame causes an area of the display screen where the image is blurred. In the event that it is determined that the first picture is not a reload picture, step 360 is performed.

In step 340, when the first frame is a heavy-load frame, the set frame rate for displaying the first frame is decreased to obtain the target frame rate.

The set frame rate for displaying the first screen frame is the frame rate of the display card when the electronic device displays the first screen frame by using the display screen, and the frame rate of the display card is the number of screen frames displayed by the display screen within 1 s.

For example, the electronic device is provided with an LCD display screen with a resolution of 1920 × 1080, the frame rate of the display card is 60Hz, that is, 60 frames are displayed each second, and the voltage of each liquid crystal capacitor needs to be refreshed 60 times within 1 s.

For the LCD display screen, if the frame rate of the video being played by the electronic device is 24Hz, that is, the number of video frames played per second is 24, the display screen continuously displays the same video frame at least twice. Each time the video frame is displayed, gray scale data is required to be input into each data line in the display screen according to the image data of the video frame, and the voltage of each liquid crystal capacitor in the display screen is refreshed.

The target frame rate in this step is usually set by a technical developer, for example, the technical developer determines the set frame rate and the target frame rate according to the resolution of the display screen of the electronic device, and the set frame rate is smaller than the target frame rate. For example, when the resolution of the display screen is 1920 × 1080, the technician may set the frame rate to be 60Hz and the target frame rate to be 50 Hz. The target frame rate may not be set in advance, and the target frame rate may be obtained by directly reducing a preset value or a random value on the basis of the set frame rate in this step.

In step 350, a second frame is displayed according to the target frame rate, wherein the second frame is an undisplayed frame.

Under the condition that the first picture frame is a displayed picture frame, the second picture frame is a picture frame after the first picture frame; when the first frame is an undisplayed frame, the second frame is the first frame.

In the present embodiment, when the first picture frame is a displayed picture frame, the second picture frame is 1 or more picture frames displayed after the first picture frame, for example, the second picture frame may be the 1 st picture frame displayed after the first picture frame, may also be n picture frames displayed after the first picture frame, and may also be a picture frame displayed within a preset time length after the first picture frame is displayed.

In the case where the first picture frame is a first picture frame that is not displayed, the second picture frame includes the first picture frame, and may further include 1 or more picture frames displayed after the first picture frame.

For the LCD display screen, when the second picture frame is displayed according to the target frame rate, the number of the picture frames required to be displayed by the display screen per second is reduced, the time for refreshing each picture frame is prolonged, the charging and discharging time of each liquid crystal capacitor is increased, and the voltage of each liquid crystal capacitor can be ensured to be increased or reduced to the voltage input on the data line.

In step 360, when the first frame is not a heavy-load frame, a second frame is displayed according to the set frame rate.

Optionally, when the first frame is a displayed frame and the second frame is a frame after the first frame, and it is detected that the second frame is not a heavy-duty frame, the frame that is not displayed is displayed according to the set frame rate.

The way for the electronic device to detect whether the second frame is the reloaded frame can refer to the method for detecting whether the first frame is the reloaded frame in steps 310 to 340 in this embodiment, which is not described herein again.

Optionally, if the electronic device detects that the second frame is a heavy-duty frame, displaying a next frame of the second frame according to the target frame rate, otherwise, displaying the next frame according to the set frame rate.
