A great advantage of the lcd tv over conventional CRT (Cathode Ray Tube) tv and plasma tv is power saving, the lcd has only half the power consumption of the same size CRT, which is much lower than the plasma; compared with the traditional CRT, the liquid crystal is better in environmental protection, because the high-voltage components such as the CRT are not arranged in the liquid crystal display, the situation that the radioactive rays exceed standards due to high voltage is avoided, the display area of the liquid crystal display does not radiate at all, only a small amount of electromagnetic waves from a driving circuit are generated, and the EMI (Electromagnetic Interference ) can be reduced by tightly sealing the shell, so that the radiation index is generally lower than that of the CRT; the liquid crystal display has a large visible area, the liquid crystal display achieves the display purpose by controlling the state of liquid crystal molecules through electrodes on the display screen, even if the screen is enlarged, the volume of the liquid crystal display is not increased in proportion (only the size is increased, the thickness is not increased, a wall-mounted function is provided for a plurality of products, a user can save more space), and the liquid crystal display is much lighter in weight than the traditional display with the same display area, the weight of the liquid crystal display is about 1/3 of that of the traditional television, so the liquid crystal display is also called a cold display or an environment-friendly display, and the LCD (Liquid Crystal Display ) is currently developing towards higher resolution, higher display image quality and larger size.

In the TFT-LCD driving, the driving mode is Line-by-Line (refer to fig. 1), when Gn signal is high, the TFT corresponding to the Line is turned on, data in the column direction can be written into the pixel, each sub-pixel simplified schematic diagram can refer to fig. 2, fig. 2 includes T controlling switch, liquid crystal capacitor Clc, storage capacitor Cst, G Line in charge of transmitting switch signal and S Line in charge of transmitting data (data), one end of Cst and Clc is the pixel electrode and the other end is the common electrode (VCOM). Because the liquid crystal is charged and discharged in a capacitor structure, if a DC (direct current) circuit is used for driving, the two ends of the capacitor inevitably generate residual charges, which is reflected on a display screen, in order to avoid the phenomenon, generally DC is changed into AC (alternating current), and the liquid crystal works by means of different voltages at the two ends, different rotations and different light transmission amounts, as shown in a waveform schematic diagram of data S-out in fig. 3, fig. 4 shows one polarity inversion mode (dot inversion) corresponding to the whole screen, the voltage of "±" is higher than that of VCOM, namely "+" higher than that of VCOM, and "-" lower than that of VCOM, and the VCOM is easily interfered by a data line to generate voltage jitter, and the voltage jitter causes the screen to generate cross talk and other anomalies.

Currently, in order to improve the problem, a Line PDF (Line detection) function is introduced, but when an ACC function (also called gamma gray level adjustment, which is to make a rising and falling motion for a gray level RGB), an OD function (to solve the smear problem, make a rising and falling motion for a previous frame of display gray level and a present frame of display gray level) or a Line OD function (to solve a bright and dark Line, make a rising and falling motion for a Line of display gray level and a present Line of display gray level) is added in the display process, the same display gray level is changed up and down because of the need for a change in the dynamic display, and if the gray level of the Line PDF is set to be in the range of the change, the condition of entering and exiting the Line PDF function exists. In addition, because of dynamic display, the number of +/-also has the jitter problem, and the situation that the Line PDF function is started and stopped repeatedly and alternately is caused, so that the picture flickering phenomenon can occur.

Based on this, the embodiment of the application provides a liquid crystal display method. The method aims to prevent the repeated alternate starting and exiting of the line detection function in the picture display process by improving the conditions of starting and exiting the line detection function, and can solve the picture flickering problem.

Referring to fig. 5, fig. 5 is a flowchart of a liquid crystal display method according to an embodiment of the application, including but not limited to steps S510 to S560.

In step S510, in the current frame display process, the sum of the positive polarity column line numbers with the sub-pixel gray-scale value greater than or equal to the first preset gray-scale threshold value on the column line corresponding to each row line is used as the total number of the first positive polarity column lines, the sum of the negative polarity column line numbers with the sub-pixel gray-scale value greater than or equal to the first preset gray-scale threshold value on the column line corresponding to each row line is used as the total number of the first negative polarity column lines, the first difference absolute value between the total number of the first positive polarity column lines and the total number of the first negative polarity column lines is determined, and the sum of the line numbers with the first difference absolute value greater than or equal to the first preset value is counted to be used as the first total line number.

In the embodiment of the application, in the process of displaying the current frame picture, the positive and negative polarities of each column line corresponding to each row and the sub-pixel gray scale value of each column line are obtained, so that the first total number of rows can be counted according to the positive and negative polarities of each column line corresponding to each row and the sub-pixel gray scale value of each column line.

Referring to fig. 6, fig. 6 is a flowchart illustrating steps for obtaining a first total number of rows according to an embodiment of the present application, including but not limited to steps S610 to S630.

In step S610, positive polarity column lines and negative polarity column lines in each row are determined according to the positive and negative polarities of the column lines corresponding to each row.

Step S620, obtaining the total number of the first positive polarity column lines and the total number of the first negative polarity column lines, of which the sub-pixel gray scale value is greater than or equal to a first preset gray scale threshold value, according to the sub-pixel gray scale values of the column lines corresponding to each row and the positive polarity column lines and the negative polarity column lines in each row;

in step S630, a first difference absolute value between the total number of the first positive polarity column lines and the total number of the first negative polarity column lines in each row is calculated, and a first total row number with the first difference absolute value greater than or equal to a first preset value is obtained.

In the embodiment of the application, for the current row, the positive and negative polarities of each column line are acquired, and the corresponding positive polarity column line and negative polarity column line in the current row can be determined. The sub-pixel gray scale values of all the column lines are obtained, so that the total number of the first positive-polarity column lines with the sub-pixel gray scale values larger than or equal to a first preset gray scale threshold value in all the positive-polarity column lines can be judged, and the total number of the first negative-polarity column lines with the sub-pixel gray scale values larger than or equal to the first preset gray scale threshold value in all the negative-polarity column lines can be judged. And calculating a first difference absolute value of the total number of the first positive polarity column lines and the total number of the first negative polarity column lines in the current row, judging whether the first difference absolute value is larger than or equal to a first preset value, and if the first difference absolute value is larger than or equal to the first preset value, enabling the current row to meet a counting condition, and adding 1 to the first total row number count. If the count value is smaller than the first preset value, the current row does not meet the count condition, and the first total row number count is increased by 0. Then, taking the next line of the current line as the current line, and executing judgment of whether the current line meets the counting condition, if yes, adding 1 to the first total line number count; if not, the first total number of rows count is incremented by 0. In this way, a first total number of numbers can be counted.

For example, the lcd panel is provided with 100 column lines in total, and based on the positive and negative polarities of the column lines corresponding to the current row, it can be determined that 40 column lines corresponding to the current row are positive polarity column lines and 60 column lines corresponding to the current row are negative polarity column lines. The total number of the first positive polarity column lines with the sub-pixel gray scale value larger than or equal to a first preset gray scale threshold value in the 40 positive polarity column lines is 25, and the total number of the first negative polarity column lines with the sub-pixel gray scale value larger than or equal to the first preset gray scale threshold value in the 60 negative polarity column lines is 45. Thus, the absolute value of the first difference between the total number of the first positive polarity column lines and the total number of the first negative polarity column lines is 20. Judging whether the first difference absolute value 20 is larger than or equal to a first preset value, if the first difference absolute value 20 is larger than or equal to the first preset value, the current row meets the counting condition, and the first total row number count is increased by 1. If the absolute value of the first difference 20 is smaller than the first preset value, the current row does not meet the counting condition, and the first total row number count is increased by 0. Then, the next line of the current line is taken as the current line, and the same judgment whether the counting condition is met is executed, so that the first total line number can be obtained through statistics.

It should be noted that the first preset gray-scale threshold is obtained by debugging in the production process of the liquid crystal display device. Based on different liquid crystal display devices, the corresponding first preset gray-scale threshold values may be different. The debugging range of the first preset gray level threshold value can be from a gray level lower limit value to a gray level upper limit value of the corresponding liquid crystal display device. For example, when the liquid crystal display device is an 8-bit panel, the debugging range of the first preset gray-scale threshold may be 0-255. When the liquid crystal display device is a 10bit panel, the debugging range of the first preset gray-scale threshold value can be 0-1023. Similarly, the first preset value is obtained by debugging based on design parameters and display effect requirements of the liquid crystal display device in the production process of the liquid crystal display device. Based on different liquid crystal display devices, the corresponding first preset values may be different.

In some embodiments, the first preset gray level threshold is greater than or equal to the first gray level threshold and less than or equal to the second gray level threshold. The second gray level threshold is a gray level upper limit value of the liquid crystal display device, and the first gray level threshold is 1/2 of the total gray level of the liquid crystal display device.

Step S520, judging whether the starting condition is satisfied according to the first total number of lines.

In the embodiment of the application, after the first total line number is obtained through statistics, whether the starting condition is met can be further judged according to the first total line number.

Referring to fig. 7, fig. 7 is a flowchart of steps for determining whether a starting condition is satisfied according to a first total number of rows, including but not limited to steps S710 to S730, according to an embodiment of the present application.

Step S710, judging whether the first total number of lines is greater than or equal to a first preset number of lines;

step S720, when the first total number of lines is greater than or equal to a first preset number of lines, determining that the starting condition is met;

in step S730, when the first total number of rows is smaller than the first preset number of rows, it is determined that the starting condition is not satisfied.

In the embodiment of the application, after the first total line number is obtained through statistics, the first total line number can be compared with the first preset line number to determine whether the starting condition of the line detection function is met. Specifically, whether the first total line number is greater than or equal to a first preset line number is determined, if the first total line number is greater than or equal to the first preset line number, the starting condition of the line detection function is determined to be satisfied, and if the first total line number is less than the first preset line number, the starting condition of the line detection function is determined not to be satisfied.

It should be noted that the first preset line number is determined in advance according to the display effect requirement, and the first preset line number is a positive integer greater than or equal to 1.

In step S530, when the start condition is satisfied, the column detection function is started.

In the embodiment of the present application, when the first total number of rows is greater than or equal to the first preset number of rows, it is determined that the start condition of the row detection function is satisfied. At this time, the column detection function is required to be activated. Namely, the high-low level time sequence of the polarity inversion control signal is output to the driving circuit, so that the driving circuit changes the corresponding electrode polarity according to the high-low level time sequence, and the positive and negative polarities of all column lines in the display process can be ensured to be symmetrical.

Step S540, when the start condition is not satisfied, the sum of positive polarity column lines with the sub-pixel gray-scale value greater than or equal to a second preset gray-scale threshold value on the column line corresponding to each row line is used as the total number of the second positive polarity column lines, the sum of negative polarity column lines with the sub-pixel gray-scale value greater than or equal to the second preset gray-scale threshold value on the column line corresponding to each row line is used as the total number of the second negative polarity column lines, a second difference absolute value between the total number of the second positive polarity column lines and the total number of the second negative polarity column lines is determined, and the sum of rows with the second difference absolute value smaller than the second preset value is counted and used as the second total number of rows, wherein the second preset gray-scale threshold value is smaller than the first preset gray-scale threshold value, and the second preset value is smaller than the first preset value.

In the embodiment of the application, when the starting condition is not satisfied, the column detection function is not started. At this time, the positive and negative polarities of the column lines and the sub-pixel gray scale values of the column lines corresponding to each row are obtained, so that the second total row number can be obtained through statistics according to the positive and negative polarities of the column lines and the sub-pixel gray scale values of the column lines corresponding to each row.

Referring to fig. 8, fig. 8 is a flowchart of a step of obtaining a second total number of rows according to an embodiment of the present application, including but not limited to steps S810 to S830.

Step S810, determining positive polarity column lines and negative polarity column lines in each row according to the positive and negative polarities of the column lines corresponding to each row.

Step S820, obtaining a total number of second positive polarity column lines and a total number of second negative polarity column lines, of which the sub-pixel gray-scale values are greater than or equal to a second preset gray-scale threshold value, according to the sub-pixel gray-scale values of the column lines corresponding to each row and the positive polarity column lines and the negative polarity column lines in each row, wherein the second preset gray-scale threshold value is smaller than the first preset gray-scale threshold value, and the second preset value is smaller than the first preset value;

in step S830, a second difference absolute value between the total number of the second positive polarity column lines and the total number of the second negative polarity column lines in each row is calculated, and a second total number of rows with the second difference absolute value smaller than a second preset value is obtained, wherein the second preset value is smaller than the first preset value.

In the embodiment of the application, for the current row, the positive and negative polarities of each column line are acquired, and the corresponding positive polarity column line and negative polarity column line in the current row can be determined. The sub-pixel gray scale values of all the column lines are obtained, so that the second positive polarity total number of sub-pixel gray scale values of all positive polarity column lines which are larger than or equal to a second preset gray scale threshold value can be judged, and the second negative polarity column line total number of sub-pixel gray scale values of all negative polarity column lines which are larger than or equal to the second preset gray scale threshold value can be judged. And calculating a second difference absolute value of the second positive polarity total number and the second negative polarity column line total number in the current row, judging whether the second difference absolute value is smaller than a second preset value, and if so, enabling the current row to meet a counting condition, and adding 1 to the second total row number count. If the current line is not smaller than the second preset value, the current line does not meet the counting condition, and the second total line count is increased by 0. Then, taking the next line of the current line as the current line, and executing judgment of whether the current line meets the counting condition, if yes, adding 1 to the second total line count; if not, the second total line count is incremented by 0. In this way, a second total number of rows may be counted.

For example, the lcd panel is provided with 100 column lines in total, and based on the positive and negative polarities of the column lines corresponding to the current row, it can be determined that 40 column lines corresponding to the current row are positive polarity column lines and 60 column lines corresponding to the current row are negative polarity column lines. The total number of the first positive polarity column lines with the sub-pixel gray scale value larger than or equal to a second preset gray scale threshold value in the 40 positive polarity column lines is 30, and the total number of the first negative polarity column lines with the sub-pixel gray scale value larger than or equal to the second preset gray scale threshold value in the 60 negative polarity column lines is 50. Thus, the absolute value of the second difference between the total number of the second positive polarity and the total number of the second negative polarity column lines is 20. Judging whether the second difference absolute value 20 is smaller than a second preset value, if the second difference absolute value 20 is smaller than the second preset value, the current line meets the counting condition, and the second total line count is increased by 1. If the second absolute value of the difference 20 is not smaller than the second preset value, the current line does not meet the counting condition, and the second total line count is increased by 0. And then taking the next line of the current line as the current line, and executing the same judgment whether the counting condition is met or not, so that the second total line number can be obtained through statistics.

Step S550, judging whether the exit condition is satisfied according to the second total number of rows.

In the embodiment of the application, after the second total number of lines is obtained through statistics, whether the starting condition is met can be further judged according to the second total number of lines.

Referring to fig. 9, fig. 9 is a flowchart of steps for determining whether an exit condition is satisfied according to a second total number of rows, including but not limited to steps S910 to S930, according to an embodiment of the present application.

Step S910, judging whether the second total line number is larger than the difference of the total line number corresponding to the display resolution minus the first preset line number;

step S920, when the second total line number is greater than the difference between the total line number corresponding to the display resolution and the first preset line number, determining that the exit condition is satisfied;

in step S930, when the second total line number is not greater than the difference between the total line number corresponding to the display resolution and the first preset line number, it is determined that the exit condition is not satisfied.

In the embodiment of the application, after the second total line number is obtained through statistics, the difference between the second total line number and the total line number corresponding to the display resolution minus the first preset line number can be compared to determine whether the exit condition of the line detection function is satisfied. Specifically, whether the second total line number is greater than the difference of the total line number corresponding to the display resolution minus the first preset line number is determined, if the second total line number is greater than the difference of the total line number corresponding to the display resolution minus the first preset line number, the exit condition of the line detection function is determined to be satisfied, and if the second total line number is not greater than the difference of the total line number corresponding to the display resolution minus the first preset line number, the exit condition of the line detection function is determined not to be satisfied.

In step S560, when the exit condition is satisfied, the column detection function is exited.

In the embodiment of the application, when the second total line number is greater than the difference between the total line number corresponding to the display resolution and the first preset line number, the exit condition meeting the line detection function is determined, and at the moment, the line detection function is exited to ensure that the positive and negative polarities of all the column lines are symmetrical in the display process. And when the second total line number is not greater than the difference between the total line number corresponding to the display resolution and the first preset line number, determining that the exit condition of the line detection function is not met, and at the moment, not executing the action of exiting the line detection function.

In the present application, during the display process of the current frame, whether to start the row detection function can be determined according to the first total number of rows, and whether to exit the row detection function can be determined according to the second total number of rows. Since the first total number of rows is determined based on the first preset gray level threshold and the first preset value, the second total number of rows is determined based on the second preset gray level threshold and the second preset value. The second preset gray level threshold value is smaller than the first preset gray level threshold value, namely, gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions are added in the setting of the starting condition and the exiting condition of the row detection function, so that the starting condition and the exiting condition of the row detection function are not in the relation, namely, the relation is not the same, and false triggering caused by gray level jitter and/or the false triggering caused by the jitter of the number of the difference between the total number of the positive and negative polarity lines can be solved through the setting of the gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions, thereby avoiding repeated alternation of the starting and the exiting of the row detection function in the picture display process and solving the picture flicker problem. Meanwhile, in the logic judgment process, whether the starting condition of the row detection function is met is judged according to the first total row number, and if yes, the row detection function is started. If not, acquiring a second total line number, judging whether the exit condition of the line detection function is met according to the second total line number, and if so, exiting the line detection function. The calculation amount can be reduced to a certain extent, and the speed of starting the column detection function can be improved.

In one embodiment of the present application, referring to fig. 10, fig. 10 is a flowchart of steps performed when the exit condition is not satisfied, including but not limited to steps S1010 to S1040, provided in the embodiment of the present application.

In step S1010, the sum of the rows satisfying the second difference absolute value being equal to or greater than the second preset value is counted as the third total row number.

In the embodiment of the application, when the exit condition is not satisfied, the action of the exit line detection function is not executed. At this time, the positive and negative polarities of the column lines and the sub-pixel gray scale values of the column lines corresponding to each row are obtained, so that the third total row number can be obtained through statistics according to the positive and negative polarities of the column lines and the sub-pixel gray scale values of the column lines corresponding to each row.

Referring to fig. 11, fig. 11 is a flowchart illustrating steps for obtaining a third total number of rows according to an embodiment of the present application, including but not limited to steps 1110 to 1130.

In step S1110, positive polarity column lines and negative polarity column lines in each row are determined according to the positive and negative polarities of the column lines corresponding to each row.

Step S1120, obtaining a second positive polarity column line total number and a second negative polarity column line total number of which the sub-pixel gray scale value is greater than or equal to a second preset gray scale threshold value in each row according to the sub-pixel gray scale values of the column lines corresponding to each row and the positive polarity column lines and the negative polarity column lines in each row;

In step S1130, a second difference absolute value between the total number of the second positive polarity column lines and the total number of the second negative polarity column lines in each row is calculated, and a third total row number with the second difference absolute value greater than or equal to a second preset value is obtained.

In the embodiment of the application, for the current row, the positive and negative polarities of each column line are acquired, and the corresponding positive polarity column line and negative polarity column line in the current row can be determined. The sub-pixel gray scale values of all the column lines are obtained, so that the second positive polarity total number of sub-pixel gray scale values of all positive polarity column lines which are larger than or equal to a second preset gray scale threshold value can be judged, and the second negative polarity column line total number of sub-pixel gray scale values of all negative polarity column lines which are larger than or equal to the second preset gray scale threshold value can be judged. And calculating a second difference absolute value of the second positive polarity total number and the second negative polarity column line total number in the current row, judging whether the second difference absolute value is larger than or equal to a second preset value, if so, the current row meets the counting condition, and the third total row count is increased by 1. If the total number of the rows is smaller than the second preset value, the current row does not meet the counting condition, and the third total row number count is increased by 0. Then, taking the next line of the current line as the current line, and executing judgment of whether the current line meets the counting condition, if yes, adding 1 to the third total line count; if not, the third total line count is incremented by 0. In this way, a third total number of rows may be counted.

For example, the lcd panel is provided with 100 column lines in total, and based on the positive and negative polarities of the column lines corresponding to the current row, it can be determined that 40 column lines corresponding to the current row are positive polarity column lines and 60 column lines corresponding to the current row are negative polarity column lines. The total number of the first positive polarity column lines with the sub-pixel gray scale value larger than or equal to a second preset gray scale threshold value in the 40 positive polarity column lines is 30, and the total number of the first negative polarity column lines with the sub-pixel gray scale value larger than or equal to the second preset gray scale threshold value in the 60 negative polarity column lines is 50. Thus, the absolute value of the second difference between the total number of the second positive polarity and the total number of the second negative polarity column lines is 20. Judging whether the second difference absolute value 20 is larger than or equal to a second preset value, if the second difference absolute value 20 is larger than or equal to the second preset value, the current line meets the counting condition, and the third total line count is increased by 1. If the second absolute value of the difference 20 is smaller than the second preset value, the current line does not meet the counting condition, and the third total line count is increased by 0. Then, the next line of the current line is taken as the current line, and the same judgment whether the counting condition is met is executed, so that the third total line number can be obtained through statistics.

Step S1020, judging whether the maintenance condition is met according to the third total number of lines.

In the embodiment of the application, after the third total number of rows is obtained through statistics, whether the maintenance condition is met can be further judged according to the third total number of rows.

Referring to fig. 12, fig. 12 is a flowchart of steps for determining whether a maintenance condition is satisfied according to a third total number of rows, including but not limited to steps S1210 to S1230, according to an embodiment of the present application.

Step S1210, judging whether the third total number of rows is greater than or equal to the first preset number of rows;

step S1220, when the third total number of lines is greater than or equal to the first preset number of lines, determining that the maintenance condition is satisfied;

in step S1230, when the third total number of rows is smaller than the first preset number of rows, it is determined that the maintenance condition is not satisfied.

In the embodiment of the present application, after the third total number of rows is obtained by statistics, the third total number of rows may be compared with the first preset number of rows to determine whether the maintenance condition of the row detection function is satisfied. Specifically, judging whether the third total line number is greater than or equal to the first preset line number, and if the third total line number is greater than or equal to the first preset line number, determining that a maintenance condition of the line detection function is met; if the third total number of rows is smaller than the first preset number of rows, determining that the maintenance condition of the row detection function is not met.

In step S1030, when the maintenance condition is satisfied, the column detection operation corresponding to the previous frame is maintained.

In the embodiment of the present application, when the third total number of lines is greater than or equal to the first preset number of lines, it is determined that the maintaining condition of the line detection function is satisfied, and at this time, the line detection action correspondingly executed by the previous frame of picture is maintained, so as to ensure that the positive and negative polarities of each column line are symmetrical in the display process. If the line detection operation executed by the previous frame is to start the line detection function, the line detection function is continuously started when the current frame is displayed. If the line detection action executed by the previous frame is the line detection function, the line detection function is continuously withdrawn when the current frame is displayed.

In step S1040, the trip detection function is disabled when the maintenance condition is not satisfied.

In the embodiment of the application, when the third total number of rows is smaller than the first preset number of rows, it is determined that the maintenance condition of the row detection function is not satisfied, and at this time, the action of moving back the row detection function is executed to ensure that the positive and negative polarities of the column lines are symmetrical in the display process.

In the present application, in the current frame display process, whether to start the line detection function can be determined according to the first total line number, whether to withdraw the line detection function can be determined according to the second total line number, and whether to maintain the line detection function executed by the previous frame can be determined according to the third total line number. Since the first total number of rows is determined based on the first preset gray level threshold and the first preset value, the second total number of rows is determined based on the second preset gray level threshold and the second preset value. The second preset gray level threshold value is smaller than the first preset gray level threshold value, namely, gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions are added in the setting of the starting condition and the exiting condition of the row detection function, so that the starting condition and the exiting condition of the row detection function are not in the relation, namely, the relation is not the same, and false triggering caused by gray level jitter and/or the false triggering caused by the jitter of the number of the difference between the total number of the positive and negative polarity lines can be solved through the setting of the gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions, thereby avoiding repeated alternation of the starting and the exiting of the row detection function in the picture display process and solving the picture flicker problem. And by supplementing the maintenance conditions, the operation of starting or exiting the row detection function can be correspondingly executed in the display process of each frame of picture.

Referring to fig. 13, fig. 13 is another flowchart of the liquid crystal display method according to the embodiment of the application, including but not limited to steps S1310 to S1350.

Step S1310, in the current frame display process, taking the sum of positive polarity column lines with the sub-pixel gray-scale value larger than or equal to a first preset gray-scale threshold value on the column line corresponding to each row line as a first positive polarity column line total number, taking the sum of negative polarity column lines with the sub-pixel gray-scale value larger than or equal to the first preset gray-scale threshold value on the column line corresponding to each row line as a first negative polarity column line total number, determining a first difference absolute value of the first positive polarity column line total number and the first negative polarity column line total number, and counting the sum of rows meeting the first difference absolute value larger than or equal to the first preset value as a first total row number;

step S1320, the sum of positive polarity column line numbers with the sub-pixel gray-scale value larger than or equal to a second preset gray-scale threshold value on the column line corresponding to each row line is used as a second positive polarity column line total number, the sum of negative polarity column line numbers with the sub-pixel gray-scale value larger than or equal to the second preset gray-scale threshold value on the column line corresponding to each row line is used as a second negative polarity column line total number, a second difference absolute value between the second positive polarity column line total number and the second negative polarity column line total number is determined, and the sum of rows meeting the second difference absolute value smaller than the second preset value is counted to be used as a second total row number, wherein the second preset gray-scale threshold value is smaller than the first preset gray-scale threshold value;

Step S1330, judging whether the starting condition is met according to the first total number of rows and judging whether the exiting condition is met according to the second total number of rows;

step S1340, when the start condition is satisfied but the exit condition is not satisfied, or when the start condition is satisfied and the exit condition is satisfied, starting the row detection function;

in step S1350, when the exit condition is satisfied but the start condition is not satisfied, the trip detection function is exited.

In the embodiment of the application, the first total line number is obtained based on the first preset gray-scale threshold value and the first preset value, and the second total line number is obtained based on the second preset gray-scale threshold value and the second preset value. And then judging whether the starting condition is met according to the first total line number and judging whether the exiting condition is met according to the second total line number. The row detection function is activated when the start condition is satisfied but the exit condition is not satisfied, or when the start condition is satisfied and the exit condition is satisfied. And when the exit condition is satisfied but the start condition is not satisfied, the trip detection function is exited. Namely, in the logic judging process, the starting condition and the exiting condition are required to be judged at the same time, and then the action of the line detection function to be executed is determined according to the judging result of the starting condition and the exiting condition.

In the present application, during the display process of the current frame, whether to start the row detection function can be determined according to the first total number of rows, and whether to exit the row detection function can be determined according to the second total number of rows. Since the first total number of rows is determined based on the first preset gray level threshold and the first preset value, the second total number of rows is determined based on the second preset gray level threshold and the second preset value. The second preset gray level threshold value is smaller than the first preset gray level threshold value, namely, gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions are added in the setting of the starting condition and the exiting condition of the row detection function, so that the starting condition and the exiting condition of the row detection function are not in the relation, namely, the relation is not the same, and false triggering caused by gray level jitter and/or the false triggering caused by the jitter of the number of the difference between the total number of the positive and negative polarity lines can be solved through the setting of the gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions, thereby avoiding repeated alternation of the starting and the exiting of the row detection function in the picture display process and solving the picture flicker problem. Meanwhile, by judging the start condition and the exit condition at the same time and determining the action of the line detection function to be executed according to the judging results of the start condition and the exit condition, the judging result can be ensured to be more correct, and the action of executing the detection function can be ensured to be more accurate.

Referring to fig. 14, fig. 14 is a flowchart of steps performed after counting a first total number of rows and a second total number of rows according to an embodiment of the present application, including but not limited to steps S1410 to S1460.

step S1440, when the exit condition is satisfied but the start condition and the maintenance condition are not satisfied, the trip detection function is exited;

step S1450, when the maintenance condition is satisfied but the start condition and the exit condition are not satisfied, maintaining the row detection action correspondingly executed for the previous frame;

in step S1460, when any two or more of the start condition, the exit condition and the sustain condition are satisfied, corresponding line detection is performed according to a preset priority, where the preset priority is that the priority of starting line detection is greater than the priority of exiting line detection and greater than the priority of sustaining the line detection performed corresponding to the previous frame of picture.

In the embodiment of the application, the first total line number is obtained based on the first preset gray-scale threshold value and the first preset value, and the second total line number and the third total line number are obtained based on the second preset gray-scale threshold value and the second preset value. And then judging whether the starting condition is met according to the first total line number, judging whether the exiting condition is met according to the second total line number, and judging whether the maintaining condition is met according to the third total line number. When the start condition is satisfied but the exit condition and the sustain condition are not satisfied, the column detection function is started. And when the exit condition is satisfied but the start condition and the sustain condition are not satisfied, the trip detection function is exited. And when the maintenance condition is met but the starting condition and the exiting condition are not met, maintaining the row detection action correspondingly executed by the previous frame of picture. When any two or more conditions of the start condition, the exit condition and the maintenance condition are met, corresponding row detection actions are executed according to the preset priority. In the logic judging process, the starting condition, the exiting condition and the maintaining condition are required to be judged simultaneously, and then the action of the line detection function to be executed is determined according to the judging results of the starting condition, the exiting condition and the maintaining condition.

In the present application, in the current frame display process, whether to start the row detection function can be determined according to the first total row number, whether to withdraw the row detection function can be determined according to the second total row number, and whether to maintain the row detection action correspondingly executed by the previous frame can be determined according to the third total row number. Since the first total number of rows is determined based on the first preset gray level threshold and the first preset value, the second total number of rows is determined based on the second preset gray level threshold and the second preset value. The second preset gray level threshold value is smaller than the first preset gray level threshold value, namely, gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions are added in the setting of the starting condition, the maintaining condition and the exiting condition of the row detection function, so that the starting condition and the exiting condition of the row detection function are not in the relation, and the problem of picture flicker is solved by setting the gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity lines meeting the corresponding conditions, so that false triggering caused by gray level jitter and/or the number of the difference between the total number of the positive and negative polarity lines can be solved, and repeated alternation of the starting and the exiting of the row detection function in the picture display process can be avoided. Meanwhile, by judging the starting condition, the exiting condition and the maintaining condition at the same time and determining the action of the line detection function to be executed according to the judging results of the starting condition, the exiting condition and the maintaining condition, the judging result can be ensured to be more correct, and each frame of picture can be ensured to correspondingly execute the action of the starting or exiting line detection function in the display process.

In the present application, during the display process of the current frame, whether to start the line detection function can be determined according to the first total line number, and whether to maintain the line detection action correspondingly executed by the previous frame can be determined according to the third total line number. Since the first total number of lines is determined based on the first preset gray-scale threshold and the first preset value, the third total number of lines is determined based on the second preset gray-scale threshold and the second preset value. The second preset gray level threshold value is smaller than the first preset gray level threshold value, namely, gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity column lines meeting the corresponding conditions are added in the setting of the starting condition and the maintaining condition of the line detection function, so that false triggering caused by gray level jitter and/or the jitter of the number of the difference between the total number of the positive and negative polarity column lines can be solved through the setting of the gray level hysteresis and the number hysteresis of the difference between the total number of the positive and negative polarity column lines meeting the corresponding conditions, and the repeated alternation of the starting and the exiting of the line detection function in the picture display process can be avoided, and the picture flicker problem is solved.
