Description

Technical Field

[0001] The present application relates to the field of display technology, and discloses a driving method of a display panel, a method for determining a driving relationship, and related devices. Background Art

[0002] With the growing demand for ultra-high-definition video, the demand for high-refresh-rate panels is increasing. However, as panel refresh rates increase, the display time per frame decreases, and the LCD requires a certain amount of time to respond. If the LCD cannot fully respond and reach the preset grayscale within a single frame, dynamic images will experience smearing. Summary of the Invention

[0003] The embodiments of the present application provide a display panel driving method, a driving relationship determination method, and related devices, which can improve the tailing phenomenon that occurs on the display panel after overdriving occurs.

[0004] In a first aspect, an embodiment of the present application provides a method for driving a display panel, which may include: obtaining a grayscale value of a first frame currently being displayed, as well as a second frame to be displayed and a third frame to be displayed, where the second frame is a next frame of the first frame, and the third frame is a next frame of the second frame;

[0005] Determining, according to a preset execution driving relationship, that the grayscale value of the first frame is switched to a first pixel grayscale value corresponding to the grayscale value of the second frame, the execution driving relationship including switching a starting grayscale value to a pixel grayscale value corresponding to a target grayscale value, the pixel grayscale value being used to display the target grayscale value, the starting grayscale value being any grayscale value among a plurality of preset grayscale values, and the target grayscale value being any grayscale value among the plurality of grayscale values;

[0006] If it is determined that the first pixel grayscale value is equal to the preset grayscale threshold parameter, the preset query driving relationship is started, and the query driving relationship includes switching the starting grayscale value to the transition grayscale value corresponding to the target grayscale value; and based on the query driving relationship, it is determined that the grayscale value of the second frame is switched to the first transition grayscale value corresponding to the grayscale value of the third frame; and based on the execution driving relationship, it is determined that the first transition grayscale value is switched to the second pixel grayscale value corresponding to the grayscale value of the third frame.

[0007] The driving method provided by the embodiments of the present application can be executed by a timing controller. In the case of overdrive, the first pixel gray scale value corresponding to the gray scale value of the second frame switched from the gray scale value of the currently displayed first frame is compared with a preset gray scale threshold parameter, so as to determine whether the liquid crystal can complete response within one frame. If the first pixel gray scale value is equal to the gray scale threshold parameter, it can be reflected that the liquid crystal cannot complete response within one frame. In this case, the timing controller can start to query the driving relationship, so as to re-determine the starting gray scale value of driving the third frame, instead of directly using the gray scale value of the second frame as the starting gray scale value of driving the third frame. In this way, the response speed of the liquid crystal can be accelerated, and the tailing phenomenon of the display panel can be improved.

[0008] In some examples, if the gray scale value of the first frame is less than the gray scale value of the second frame, the gray scale threshold parameter is 255, and the timing controller can compare the first pixel gray scale value with 255. In other examples, if the gray scale value of the first frame is greater than the gray scale value of the second frame, the gray scale threshold parameter is 0, and the timing controller can compare the first pixel gray scale value with 0.

[0009] In a possible design, the driving method provided by the embodiments of the present application can further include:

[0010] If it is determined that the first pixel gray scale value is not equal to the gray scale threshold parameter, the gray scale value of the second frame switched from the gray scale value of the third frame is determined as a third pixel gray scale value corresponding to the gray scale value of the third frame based on the execution of the driving relationship.

[0011] In the embodiments of the present application, if the first pixel gray scale value is not equal to the gray scale threshold parameter, it can be reflected that the liquid crystal can complete response within one frame, the timing controller can not start to query the driving relationship, but according to the execution of the driving relationship, the gray scale value of the second frame is used as the starting gray scale to drive the third frame.

[0012] In a possible design, in the driving method provided by the embodiments of the present application, after the first overdrive gray scale value switched from the gray scale value of the third frame is determined as a second pixel gray scale value corresponding to the gray scale value of the third frame based on the execution of the driving relationship, the method further includes:

[0013] The gray scale value of a target frame is acquired, the target frame being a frame after the third frame;

[0014] Based on the query-driven relationship, it is determined that the gray scale value of the previous frame of the target frame is switched to a second over-gray scale value corresponding to the gray scale value of the target frame; and after it is determined that the second over-gray scale value is equal to the gray scale value of the target frame, the query-driven relationship is terminated, and the target frame is taken as the first frame; or, after it is determined that the second over-gray scale value is not equal to the gray scale value of the target frame, based on the execution-driven relationship, it is determined that the second over-gray scale value is switched to a fourth pixel gray scale value corresponding to the gray scale value of the target frame.

[0015] In the embodiments of the present application, after the timing controller starts the query-driven relationship, for the frames after the third frame, it can be determined in turn whether the second over-gray scale value corresponding to each frame is switched from the gray scale value of the previous frame of the frame, and whether it is equal to the gray scale value of the frame. If they are equal, it can be reflected that the liquid crystal can respond in time to the driving of the frame, and the timing controller can terminate the use of the query-driven relationship.

[0016] After the driving method provided by the embodiments of the present application is executed, in one possible case, the gray scale value of the first frame is less than the gray scale value of the second frame; in the luminance change waveform of the process of the display panel displaying the first frame, the second frame, the third frame and the fourth frame in turn, in two adjacent time points, the gray scale value of the previous time point is less than the gray scale value of the next time point.

[0076] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments described in the present application document, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the technical solutions of the present application.

[0077] With the continuous improvement of the refresh rate of the display panel, the display time of each frame of picture is shortened. However, the liquid crystal response in the display panel needs some time. If the liquid crystal cannot complete the response within a frame to reach the preset gray scale, the presented picture will have a trailing phenomenon. With the increasing number of frames of liquid crystal response, the trailing phenomenon is more serious.

[0078] Therefore, the embodiments of the present application provide a display panel driving method, which can improve the trailing phenomenon of the high refresh rate panel.

[0079] Please refer to Figure 1 An exemplary application scenario schematic diagram provided by the embodiments of the present application is shown. In the Figure 1 In the embodiments of the present application, the display panel is usually provided with a timing controller (TCON), which can convert a video signal into a digital signal of the voltage required by the driving circuit. Figure 1As shown in FIG. 1, the timing controller can be connected with the display panel through an interface module (the rectangle with diagonal lines). Figure 1 The application scenario of the timing controller is only used for example and does not limit the connection relationship between the display panel and the timing controller.

[0080] Figure 2 The driving method provided by the embodiments of the present application is exemplarily shown, which can be executed by the controller and can include the following steps.

[0081] In S201, the gray scale value of the currently displayed first frame and the second frame to be displayed and the third frame to be displayed are obtained, the second frame is the next frame of the first frame, and the third frame is the next frame of the second frame.

[0082] In the implementation, the controller can receive a video signal and determine the gray scale value of each frame in the video signal. The gray scale value can reflect or represent the brightness of the display. The gray scale value of the image frame is related to the bit width of the data signal of the video signal. In some examples, the data signal of the video signal is 8 bits (bit), and the gray scale value ranges from 0 to 255. The gray scale value is an integer, and it can be seen that 256 gray scale values can be configured in this example. In other examples, as the data signal of the video signal expands, the data signal can be greater than 8 bits, and the gray scale value range will also expand. The display panel driving method provided by the embodiments of the present application can also be applied to such a case. The present application does not make too many limitations.

[0083] In the video signal, the controller can obtain or determine the gray scale value of each of the two adjacent frames. The controller executes the driving method provided by the embodiments of the present application on the two adjacent frames, which can improve the tailing phenomenon of the display panel when the previous frame is switched to the next frame.

[0084] In the actual application scenario, the controller can execute the driving method provided by the embodiments of the present application in the case of overdrive. In step S201, the currently displayed frame is the first frame in which overdrive occurs. In other words, the gray scale jump occurs in the process of displaying the first frame. Assuming that the previous frame of the currently displayed frame is frame A0. The gray scale value of frame A0 is less than the gray scale value of the currently displayed frame, and the pixel gray scale value corresponding to the gray scale value of frame A0 switched to the gray scale value of the currently displayed frame is greater than the gray scale value of the currently displayed frame, which can be determined as overdrive. Or, the gray scale value of frame A0 is greater than the gray scale value of the currently displayed frame, and the pixel gray scale value corresponding to the gray scale value of frame A0 switched to the gray scale value of the currently displayed frame is less than the gray scale value of the currently displayed frame, which can be determined as overdrive. In the case of overdrive, the controller can trigger the operation in steps S201-203.

[0085] For the convenience of introduction, the current display frame is referred to as the first frame, the next frame of the first frame is referred to as the second frame, and the next frame of the second frame is referred to as the third frame.

[0086] The controller can pre-store an execution driving relationship, and the execution driving relationship includes that, in a plurality of preset gray scale values, any two gray scale values are switched to correspond to a pixel gray scale value. In other words, the execution driving relationship can include that a starting gray scale value is switched to a pixel gray scale value corresponding to a target gray scale value, and the pixel gray scale value is used to display the target gray scale value. For example, the controller can send a voltage corresponding to the pixel gray scale value to a liquid crystal driving circuit, so as to drive the liquid crystal. The starting gray scale value is any gray scale value in the plurality of preset gray scale values, and the target gray scale value is any gray scale value in the plurality of gray scale values.

[0087] For the convenience of introduction, the storage form of the execution driving relationship table is taken as an example. Please refer to the execution driving relationship table in Figure 3 For the two adjacent frames obtained by the controller, in the execution driving relationship table (solid line part), a plurality of gray scale values that increase sequentially are recorded in the row direction (dotted line part 1). One gray scale value in the row direction can represent a gray scale value of a previous frame (which can also be a current display frame) in the two adjacent frames, and a plurality of gray scale values that increase sequentially are recorded in the column direction (dotted line part 2). One gray scale value in the column direction can represent a gray scale value of a next frame (which can also be a next frame of the current display frame) in the two adjacent frames. In the execution driving relationship table, a number in the i-th row and the j-th column represents that the gray scale value of the previous frame is the j-th gray scale value in the row direction (dotted line part 1), and the gray scale value of the next frame is a pixel gray scale value corresponding to the i-th gray scale value in the column direction (dotted line part 2). The j-th gray scale value is the j-th one in the plurality of gray scale values that increase sequentially in the row direction, and the i-th gray scale value is the i-th one in the plurality of gray scale values that increase sequentially in the column direction. Generally, the sequence of the plurality of gray scale values that increase sequentially in the row direction is the same as the sequence of the plurality of gray scale values that increase sequentially in the column direction.

[0088] It should be noted that, Figure 3 It is shown in the execution driving relationship table that the execution driving relationship table is 5*5, which is only used to introduce and explain the execution driving relationship table, and does not specifically limit the actual form of the execution driving relationship table. In actual application scenarios, the execution driving relationship table can also be 17*17 or 33*33. The size of the execution driving relationship is N*N, which can reflect that the gray scale value range [0, 255] is divided into N parts. The execution driving relationship can reflect that any one gray scale value in N gray scale values is switched to a pixel gray scale value corresponding to any one gray scale value in the N gray scale values.

[0089] It can be seen that in the execution driving relationship, the grayscale value of the previous frame of the first frame is switched to the grayscale value of the first frame, and the pixel grayscale value corresponding to the grayscale value is greater than the grayscale value of the first frame. In this case, the controller executes the operations in steps S201-203.

[0090] S202 : According to a preset execution driving relationship, determine whether the grayscale value of the first frame is switched to a first pixel grayscale value corresponding to the grayscale value of the second frame.

[0091] The controller can execute the driving relationship to determine the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame. The first pixel grayscale value can be used to generate or determine the liquid crystal driving voltage required for switching from the first frame to the second frame.

[0092] Optionally, after determining that the grayscale value of the first frame switches to the first pixel grayscale value corresponding to the grayscale value of the second frame, the controller can provide the first pixel grayscale value to a module that generates a liquid crystal driving voltage, so that the module provides the liquid crystal with a driving voltage corresponding to the first pixel grayscale value.

[0093] S203, if it is determined that the first pixel grayscale value is equal to the preset grayscale threshold parameter, then start using the preset query driving relationship, the query driving relationship includes switching the starting grayscale value to the transition grayscale value corresponding to the target grayscale value; and based on the query driving relationship, determine that the grayscale value of the second frame is switched to the first transition grayscale value corresponding to the grayscale value of the third frame; and based on the execution driving relationship, determine that the first transition grayscale value is switched to the second pixel grayscale value corresponding to the grayscale value of the third frame.

[0094] In specific implementation, the controller can switch the grayscale value of the first frame determined in step S203 to the first pixel grayscale value corresponding to the grayscale value of the second frame, and compare it with the preset grayscale value threshold parameter to determine whether the first pixel grayscale value is equal to the preset grayscale value threshold parameter.

[0095] If the grayscale value of the first pixel is equal to the preset grayscale value threshold parameter, it can be reflected that after the overdrive occurs, it is difficult for the liquid crystal to reach the grayscale value of the second frame within the duration of one frame, which will aggravate the tailing phenomenon. To improve the tailing phenomenon, the controller can not use the grayscale value of the second frame as the starting grayscale value when determining the pixel grayscale value required for switching to display the third frame. By adjusting the starting grayscale value of the grayscale value switched to the third frame. The liquid crystal drive circuit determines the pixel grayscale value required to display the third frame in this way, which can speed up the liquid crystal deflection speed and accelerate the liquid crystal response for liquid crystal driving.

[0096] To this end, the embodiment of the present application provides a query driving relationship, which may include the transition grayscale value corresponding to the switching between any two grayscale values ​​among the multiple grayscale values. For ease of introduction, the query driving relationship is taken as an example of a storage form of a table.

[0097] Please combine Figure 4 For two adjacent frames acquired by the controller, in the query drive relationship table (solid line portion), multiple grayscale values ​​that increase in sequence are recorded in the row direction (dashed line portion 3). A grayscale value in the row direction can represent the grayscale value of the previous frame (or the currently displayed frame) between the two adjacent frames. Multiple grayscale values ​​that increase in sequence are recorded in the column direction (dashed line portion 4). A grayscale value in the column direction can represent the grayscale value of the next frame (or the next frame of the currently displayed frame) between the two adjacent frames.

[0098] In the query driving relationship table, the number in row a, column b indicates that the grayscale value of the previous frame is the bth grayscale value in the row direction (dashed line portion 3), and the grayscale value of the next frame is the transition grayscale value corresponding to the ath grayscale value in the column direction (dashed line portion 4). This transition grayscale value serves as the starting grayscale value for switching to the next frame.

[0099] The bth grayscale value is the bth grayscale value among the plurality of grayscale values ​​that increase sequentially in the row direction, and the ath grayscale value is the ath grayscale value among the plurality of grayscale values ​​that increase sequentially in the column direction. Typically, the sequence of the plurality of grayscale values ​​that increase sequentially in the row direction is the same as the sequence of the plurality of grayscale values ​​that increase sequentially in the column direction.

[0100] It should be noted that Figure 4 The query drive relationship table is shown as 5*5, which is only used as an introduction to the query drive relationship table and does not serve as a specific limitation on the actual form of the query drive relationship table. In actual application scenarios, the query drive relationship table can also be 17*17 or 33*33. The query drive relationship size is N*N, which can reflect that the grayscale value range [0, 255] is divided into N parts. The query drive relationship can reflect any grayscale value among the N grayscale values. Switching to any grayscale value of the N grayscale values ​​requires inserting the grayscale value of the transition frame.

[0101] It should be clarified that the execution drive relationship and the query drive relationship in this application are two different relationships. Among them, the execution drive relationship is used to determine the pixel grayscale value corresponding to the switch from one frame to another, and the pixel grayscale value can represent the required grayscale jump amount. The pixel grayscale value is used to generate the driving voltage of the liquid crystal. The query drive relationship is used to determine the starting grayscale value C used between frame A and frame B. The controller can determine the pixel grayscale value corresponding to the grayscale value of frame B based on the execution drive relationship, and drive the liquid crystal to display frame B.

[0102] Through the above introduction, the controller can determine whether the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame is equal to the grayscale threshold parameter, to determine whether the liquid crystal can reach the grayscale value of the second frame within a frame after the overdrive occurs. If it is determined that the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame is equal to the grayscale threshold parameter, it is determined that the liquid crystal cannot reach the grayscale value of the second frame within a frame, which will exacerbate the trailing phenomenon caused by overdrive. If it is determined that the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame is not equal to the grayscale threshold parameter, it can be determined that the liquid crystal can reach the grayscale value of the second frame within a frame, which will not exacerbate the trailing phenomenon caused by overdrive.

[0103] In one possible case, the controller determines that the trailing phenomenon caused by overdrive occurs, and starts to query the driving relationship, which is also when it is determined that the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame is equal to the preset grayscale threshold parameter. The controller determines the starting grayscale value required for switching to the pixel grayscale value corresponding to the third frame. That is, based on the query driving relationship, the controller determines the first overshoot grayscale value corresponding to the grayscale value of the second frame switching to the grayscale value of the third frame; and based on the execution driving relationship, the controller determines the second pixel grayscale value corresponding to the first overshoot grayscale value switching to the grayscale value of the third frame. The controller can provide the second pixel grayscale value to the liquid crystal driving circuit to drive the liquid crystal.

[0104] In another possible case, the controller determines that the trailing phenomenon caused by overdrive does not occur, which is also when it is determined that the first pixel grayscale value corresponding to the grayscale value of the first frame switching to the grayscale value of the second frame is not equal to the preset grayscale threshold parameter. The controller does not start to query the driving relationship, and determines the third pixel grayscale value corresponding to the grayscale value of the second frame switching to the grayscale value of the third frame based on the execution driving relationship. The controller can provide the third pixel grayscale value to the liquid crystal driving circuit to drive the liquid crystal.

[0105] In one possible implementation, the grayscale value threshold parameter can be any one of 0 or 255. In one possible case, if the grayscale value of the first frame in step S201 is less than the grayscale value of the second frame, the grayscale value threshold parameter in step S203 is configured as 255. The controller determines that the grayscale value of the first frame is less than the grayscale value of the second frame, and then compares the first pixel grayscale value with 255 to determine whether the first pixel grayscale value is equal to 255. In this case, the grayscale value of the currently displayed first frame is less than the grayscale value of the second frame, and the first pixel grayscale value is equal to 255, which can reflect that overdrive occurs.

[0106] In another possible case, if the gray scale value of the current displayed first frame in step S201 is greater than the gray scale value of the second frame, the gray scale value threshold parameter in step S203 is configured as 0. The controller determines that the gray scale value of the first frame is greater than the gray scale value of the second frame, and can compare the first pixel gray scale value with 0 to determine whether the pixel gray scale value is equal to 0. In this case, the gray scale value of the first frame is greater than the gray scale value of the second frame, and the first pixel gray scale value is equal to 0, which can reflect that overdrive occurs.

[0107] After starting to use the query driving relationship, the controller further improves the trailing phenomenon caused by overdrive to accelerate the response speed of the liquid crystal. The controller can traverse each frame after the third frame, and can perform the driving method as shown in the following table until the query driving relationship is terminated. Figure 5 The driving method shown in the table is terminated until the query driving relationship is terminated.

[0108] S501, obtaining a gray scale value of a target frame s;

[0109] S502, based on the query driving relationship, determining that the gray scale value of a previous frame of the target frame s is switched to a second overdrive gray scale value corresponding to the gray scale value of the target frame.

[0110] S503, determining whether the second overdrive gray scale value is equal to the gray scale value of the target frame s, if yes, the next step is step S504, and if no, the next step is step S505.

[0111] If the second overdrive gray scale value is equal to the gray scale value of the target frame s, it can be reflected that the overdrive condition ends. If the second overdrive gray scale value is not equal to the gray scale value of the target frame s, it can be reflected that the overdrive condition does not end.

[0112] S504, terminating the use of the query driving relationship.

[0113] If the second overdrive gray scale value is equal to the gray scale value of the target frame s, the controller can terminate the use of the query driving relationship. The controller can perform the driving operation in the case where overdrive does not occur. For example, according to the execution driving relationship, it is determined that the gray scale value of the previous frame of the target frame s is switched to a target pixel gray scale value corresponding to the gray scale value of the target frame s. It is determined whether the target pixel gray scale value is greater than the gray scale value of the target frame s, so as to determine whether overdrive occurs. If it is determined that overdrive occurs, the controller can take the target frame s as the first frame, and perform the operations in steps S201-203. If the overdrive condition does not occur, the controller can perform the driving operation in the case where overdrive does not occur on the next frame of the target frame s.

[0114] S505, based on the execution driving relationship, determining that the second overdrive gray scale value is switched to a fourth pixel gray scale value corresponding to the gray scale value of the target frame s.

[0115] If the second excessive gray scale value is not equal to the gray scale value of the target frame s, the controller uses the second excessive gray scale value as a starting gray scale value, determines, based on the execution driving relationship, that the second excessive gray scale value switches to a fourth pixel gray scale value corresponding to the gray scale value of the target frame s, and accelerates the liquid crystal response speed. After the execution of step S505, the controller can update the next frame of the target frame s as the target frame s (i.e., s = s + 1), and repeat the operations in steps S501-505.

[0116] Figure 6 An exemplary driving method of a display panel is shown, which can be executed by a controller, and can include the following steps:

[0117] S601, obtaining gray scale values of multiple frames in a video signal, the gray scale values of the multiple frames including a gray scale value of a qth frame and a gray scale value of a (q+1)th frame.

[0118] Optionally, when the controller first executes step S601, the controller can record the first frame of the video signal as the qth frame.

[0119] S602, determining, based on the execution driving relationship, that the gray scale value of the qth frame switches to a pixel gray scale value Dq+1 corresponding to the gray scale value of the (q+1)th frame.

[0120] S603, judging whether the gray scale value of the qth frame, the pixel gray scale value Dq+1, and the gray scale value of the (q+1)th frame satisfy a preset condition, if yes, executing step S604 next, and if no, executing step S605 next.

[0121] The preset condition can include:

[0122] Condition 1: the gray scale value of the qth frame is less than the gray scale value of the (q+1)th frame, and the pixel gray scale value Dq+1 is greater than the gray scale value of the (q+1)th frame.

[0123] Condition 2: the gray scale value of the qth frame is greater than the gray scale value of the (q+1)th frame, and the pixel gray scale value Dq+1 is less than the gray scale value of the (q+1)th frame.

[0124] Among them, the gray scale value of the qth frame, the pixel gray scale value Dq+1 and the (q+1)th frame meet condition 1 or condition 2, which can be determined to satisfy the preset condition, and whether overdrive occurs is judged.

[0125] S604, determining that the (q+1)th frame occurs overdrive.

[0126] After the controller determines that the pixel gray scale value Dq+1 is greater than the gray scale value of the (q+1)th frame, the controller can directly execute the operation in step S606 in some application scenarios.

[0127] S605, determining that the (q+1)th frame does not occur overdrive.

[0128] The controller can update q+1 to q, and execute the operation in step S602 again.

[0129] S606, determining a pixel gray scale value Dq+2 corresponding to the gray scale value of the q+2th frame according to the execution driving relationship.

[0130] S607, judging whether the pixel gray scale value Dq+2 is equal to a gray scale threshold parameter, if yes, the next step executes step S608, if no, updating q+2 to q, and executing the operation in step S602 again.

[0131] Wherein, if the gray scale value of the q+1th frame is less than the gray scale value of the q+2th frame, the gray scale threshold parameter in step S607 is 255. If the gray scale value of the q+1th frame is greater than the gray scale value of the q+2th frame, the gray scale threshold parameter in step S607 is 0.

[0132] S608, starting the query driving relationship.

[0133] S609, determining an over gray scale value Gq+3 corresponding to the gray scale value of the q+3th frame according to the query driving relationship.

[0134] S610, determining a pixel gray scale value Dq+3 corresponding to the gray scale value of the q+3th frame according to the execution driving relationship.

[0135] S611, determining an over gray scale value Gq+4 corresponding to the gray scale value of the q+4th frame according to the query driving relationship.

[0136] S612, judging whether the over gray scale value Gq+4 is equal to the gray scale value of the q+4th frame, if yes, the next step executes step S613, if no, updating q+1 to q, and executing the operation in step S609.

[0137] S613, terminating the use of the query driving relationship.

[0138] The controller executing step S612 can reflect that the tailing situation caused by the current overdrive has been improved. The controller can update q+3 to q, and execute the operation in step S602 again.

[0139] In some examples, the controller executing the process of step S607 can refer to the method shown in FIG. 7. Figure 7 The method can include the following steps:

[0140] S701, judging whether the gray scale value of the q+1th frame is less than the gray scale value of the q+2th frame, if yes, the next step executes step S702, if no, the next step executes step S703.

[0141] S702, determining whether the pixel gray scale value Dq+2 is equal to 255, if yes, the next step is executed step S704, if no, the next step is executed step S705.

[0142] S703, determining whether the gray scale value of the q+1 frame is greater than the gray scale value of the q+2 frame, if yes, the next step is executed step S706, if no, the next step is executed step S705.

[0143] S704, determining that the pixel gray scale value Dq+2 is equal to the gray scale threshold parameter, the next step is executed step S608.

[0144] S705, determining that the pixel gray scale value Dq+2 is not equal to the gray scale threshold parameter, updating q+2 to q, and executing step 602.

[0145] S706, determining whether the pixel gray scale value Dq+2 is equal to 0, if yes, the next step is executed step S704, if no, the next step is executed step S705.

[0146] It should be noted that, Figure 7 the execution process of each step in the above table is only used for example, and the execution order of S701, S702 and S706 can be flexibly adjusted in actual application scenarios. The embodiments of the present application do not make specific limitation on this.

[0147] Please combine Figure 8 , assuming that the frame A1 is less than the frame B1 scene, the gray scale value of the frame A1 is switched to the pixel gray scale value corresponding to the gray scale value of the frame B1, which is greater than the gray scale value X_B1 of the frame B1, that is, the frame B1 occurs overdrive. The frames after frame B1 are frame M1, frame S1 and frame P1. Figure 8The actual gray scale change curve of the display panel in the process that the controller drives frame A1, frame B1, frame M1, frame S1 and frame P1 in turn is shown. After the controller uses the driving method of the display panel provided in the embodiments of the present application, the controller can adjust the starting gray scale value of the gray scale value of frame B1 switching to the gray scale value of frame M1, determine the overdrive gray scale value GB1M1 corresponding to the gray scale value of frame B1 switching to the gray scale value of frame M1 as the starting gray scale value of switching to frame M1 based on the query driving relationship. The controller can determine the pixel gray scale value X_M1 corresponding to the gray scale value of frame M1 switching to the gray scale value of frame M1 based on the execution driving relationship. Similarly, the controller can adjust the starting gray scale value of the gray scale value of frame M1 switching to the gray scale value of frame S1, determine the overdrive gray scale value GM1S1 corresponding to the gray scale value of frame M1 switching to the gray scale value of frame S1 as the starting gray scale value of switching to frame S1 based on the query driving relationship. The controller can determine the pixel gray scale value X_S1 corresponding to the gray scale value of frame S1 switching to the gray scale value of frame S1 based on the execution driving relationship. The controller can adjust the starting gray scale value of the gray scale value of frame S1 switching to the gray scale value of frame P1, determine the overdrive gray scale value GS1P1 corresponding to the gray scale value of frame S1 switching to the gray scale value of frame P1 based on the query driving relationship, wherein the overdrive gray scale value GS1P1 is equal to the gray scale value of frame P1, and the controller can terminate the use of the query driving relationship. The controller can determine the pixel gray scale value X_P1 corresponding to the gray scale value of frame S1 switching to the gray scale value of frame P1 based on the execution driving relationship.

[0148] By Figure 8 It can be seen that after overdrive occurs in frame B1, the controller executes the driving method provided in the embodiments of the present application, which can accelerate the liquid crystal response speed, so that the pixel gray scale values of each frame after overdrive are closer and closer to the gray scale values of the frames, and the trailing phenomenon on the display panel can also be improved.

[0149] Please combine Figure 9 Assuming that in the scenario that frame A2 is greater than frame B2, the pixel gray scale value corresponding to the gray scale value of frame A2 switching to the gray scale value of frame B2 is less than the gray scale value X_B2 of frame B2, that is, overdrive occurs in frame B2. The frames after frame B2 are frame M2, frame S2 and frame P2. Figure 9The actual gray scale change curve of the display panel in the process that the controller drives frame A2, frame B2, frame M2, frame S2 and frame P2 in turn is shown. After the controller uses the driving method of the display panel provided in the embodiments of the present application, the controller can adjust the starting gray scale value of the gray scale value of frame B2 switching to the gray scale value of frame M2, determine the over gray scale value GBM2 corresponding to the gray scale value of frame B2 switching to the gray scale value of frame M2 as the starting gray scale value of switching to frame M2 based on the query driving relationship. The controller can determine the pixel gray scale value X_M2 corresponding to the gray scale value of frame M2 switching to the gray scale value of frame M2 based on the execution driving relationship. Similarly, the controller can adjust the starting gray scale value of the gray scale value of frame M2 switching to the gray scale value of frame S2, determine the over gray scale value GMS2 corresponding to the gray scale value of frame M2 switching to the gray scale value of frame S2 as the starting gray scale value of switching to frame S2 based on the query driving relationship. The controller can determine the pixel gray scale value X_S2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame S2 based on the execution driving relationship. The controller can adjust the starting gray scale value of the gray scale value of frame S2 switching to the gray scale value of frame P2, determine the over gray scale value GSP2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame P2 based on the query driving relationship, wherein the over gray scale value GSP2 is equal to the gray scale value of frame P2, and the controller can terminate using the query driving relationship. The controller can determine the pixel gray scale value X_P2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame P2 based on the execution driving relationship.

[0150] According to the driving method of the display panel provided in the embodiments of the present application, the controller can adjust the starting gray scale value of the gray scale value of frame B2 switching to the gray scale value of frame M2, determine the over gray scale value GBM2 corresponding to the gray scale value of frame B2 switching to the gray scale value of frame M2 as the starting gray scale value of switching to frame M2 based on the query driving relationship, and determine the pixel gray scale value X_M2 corresponding to the gray scale value of frame M2 switching to the gray scale value of frame M2 based on the execution driving relationship. Similarly, the controller can adjust the starting gray scale value of the gray scale value of frame M2 switching to the gray scale value of frame S2, determine the over gray scale value GMS2 corresponding to the gray scale value of frame M2 switching to the gray scale value of frame S2 as the starting gray scale value of switching to frame S2 based on the query driving relationship, and determine the pixel gray scale value X_S2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame S2 based on the execution driving relationship. The controller can adjust the starting gray scale value of the gray scale value of frame S2 switching to the gray scale value of frame P2, determine the over gray scale value GSP2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame P2 based on the query driving relationship, wherein the over gray scale value GSP2 is equal to the gray scale value of frame P2, and the controller can terminate using the query driving relationship. The controller can determine the pixel gray scale value X_P2 corresponding to the gray scale value of frame S2 switching to the gray scale value of frame P2 based on the execution driving relationship. Figure 9 It can be seen that after over driving of frame B2, the controller executes the driving method provided in the embodiments of the present application, which can accelerate the liquid crystal response speed, so that the pixel gray scale values of each frame after over driving are closer and closer to the gray scale value of the frame, and the trailing phenomenon on the display panel can also be improved.

[0151] Based on the same inventive concept, the present application also provides a determination method of a driving relationship, which is used to generate the query driving relationship described above, so as to accelerate the liquid crystal response speed and improve the trailing phenomenon caused by over driving.

[0152] The determination method of the driving relationship can be executed by a generation system. Figure 10 An exemplary structure schematic diagram of a generation system is shown, which can include a signal acquisition device and a processing device.

[0153] The signal acquisition device can include an optical sensor and a signal converter. The optical sensor can be used to acquire the light signal of the target display panel. The signal converter is used to convert the light signal into a voltage signal and output to the processing device.

[0154] The processing device can be connected with the timing controller. The processing device can be connected with the timing controller by using any existing data transmission protocol or communication protocol. Alternatively, the processing device and the timing controller can use I2C data transmission protocol for data transmission. In some application scenarios, the processing device and the timing controller can be connected through a USB-to-I2C module for data transmission.

[0155] The timing controller can be connected with the target display panel, and used to provide a pixel gray scale value to the target display panel, so as to generate a driving voltage corresponding to the pixel gray scale value and drive liquid crystal of the target display panel.

[0156] The processing device can send an initial query driving relationship to the timing controller. In some examples, the processing device can send an updated query driving relationship to the timing controller, so that the timing controller replaces the previously stored query driving relationship with the latest received query driving relationship. In other examples, as shown in FIG. 8, the processing device can send a modification instruction to the timing controller, so that the timing controller modifies a parameter in the query driving relationship stored in the register, thereby updating the query driving relationship. Alternatively, the generation system can include the timing controller. Figure 11

[0157] In a possible design, the processing device can send a generated gray scale switching command to the timing controller, the gray scale switching command carrying gray scale values of a plurality of test frames, and the gray scale switching command being used to instruct the timing controller to drive the test frames in sequence. The timing controller drives the test frames in sequence, and when it is determined that overdrive occurs, the driving method provided in the embodiments of the present application is executed.

[0158] Alternatively, the gray scale value of the first test frame and the gray scale value of the second test frame can be any two gray scale values in the execution driving relationship. Alternatively, the gray scale value of the first test frame and the gray scale value of the second test frame have the following relationship: in the execution driving relationship, the pixel gray scale value corresponding to the gray scale value of the first test frame switching to the gray scale value of the second test frame is equal to 255, or the pixel gray scale value corresponding to the gray scale value of the first test frame switching to the gray scale value of the second test frame is equal to 0.

[0159] The timing controller can pre-store the execution driving relationship and the target query driving relationship. The target query driving relationship can be a query driving relationship received by the timing controller last time, or a query driving relationship modified by the timing controller last time.

[0160] ​Optionally, in the query-driven relationship first received by the timing controller, the overstep gray scale value corresponding to any gray scale value to which a gray scale value switches is identical to the any gray scale value. Alternatively, in the initial query-driven relationship stored by the timing controller, the overstep gray scale value corresponding to any gray scale value to which a gray scale value switches is identical to the any gray scale value. The timing controller can determine, according to a preset execution-driven relationship, a fifth pixel gray scale value corresponding to a gray scale value of a second test frame to which a gray scale value of a first test frame switches; wherein the execution-driven relationship comprises a pixel gray scale value corresponding to a target gray scale value to which a starting gray scale value switches, the pixel gray scale value being used to display the target gray scale value, the starting gray scale value being any gray scale value in a plurality of preset gray scale values, the target gray scale value being any gray scale value in the plurality of gray scale values; and the gray scale switching command is used to instruct driving a plurality of test frames, the plurality of test frames comprising the first test frame, the second test frame and a third test frame to be displayed in sequence.

[0161] If the fifth pixel gray scale value is equal to a preset gray scale value threshold parameter, a preset target query-driven relationship is started to be used, the target query-driven relationship comprising an overstep gray scale value corresponding to the target gray scale value to which the starting gray scale value switches; and based on the target query-driven relationship, a third overstep gray scale value corresponding to a gray scale value of the third test frame to which the gray scale value of the second test frame switches is determined; and based on the execution-driven relationship, a sixth pixel gray scale value corresponding to the gray scale value of the third test frame to which the third overstep gray scale value switches is determined.

[0162] In a possible case, the gray scale value of the first test frame is greater than the gray scale value of the second test frame, and the fifth pixel gray scale value is equal to the gray scale value threshold parameter; after the timing controller determines the fifth pixel gray scale value corresponding to the gray scale value of the second test frame to which the gray scale value of the first test frame switches, the timing controller switches the gray scale value of the second test frame to a pixel gray scale value corresponding to the gray scale value of the second test frame, the pixel gray scale value being used to display the second test frame.

[0163] In the above design, when the timing controller in the generation system drives a plurality of test frames, the timing controller executes the driving method of the display panel provided in the foregoing embodiments.

[0164] In another possible design, the processing device in the generation system can perform the operation of determining the excessive grayscale value in the driving method of the display panel on a plurality of test frames. For example, the processing device can determine, according to a preset execution driving relationship, that the grayscale value of the first test frame is switched to a fifth pixel grayscale value corresponding to the grayscale value of the second test frame; the execution driving relationship includes that a starting grayscale value is switched to a pixel grayscale value corresponding to a target grayscale value, the pixel grayscale value is used to display the target grayscale value, the starting grayscale value is any grayscale value in a plurality of preset grayscale values, and the target grayscale value is any grayscale value in the plurality of grayscale values; the grayscale switching command is used to instruct driving a plurality of test frames, and the plurality of test frames include the first test frame, the second test frame, and a third test frame to be displayed in sequence; and the processing device can send a first switching instruction to the timing controller to instruct the timing controller to perform the operation of switching the grayscale value of the first test frame to the grayscale value of the second test frame.

[0165] If the fifth pixel grayscale value is equal to a preset grayscale value threshold parameter, the processing device starts to determine, using a query driving relationship updated most recently (or an initial stored query driving relationship), that the grayscale value of the second test frame is switched to a third excessive grayscale value corresponding to the grayscale value of the third test frame, the third excessive grayscale value is used to determine, based on the execution driving relationship, that the third excessive grayscale value is switched to a sixth pixel grayscale value corresponding to the grayscale value of the third test frame. The processing device can send a second switching instruction to the timing controller to instruct the timing controller to perform the operation of switching the third excessive grayscale value to the grayscale value of the third test frame.

[0166] Optionally, the grayscale value of the first test frame and the grayscale value of the second test frame can be any two grayscale values in the execution driving relationship. Alternatively, the grayscale value of the first test frame and the grayscale value of the second test frame have the following relationship: in the execution driving relationship, the pixel grayscale value corresponding to the grayscale value of the first test frame switched to the grayscale value of the second test frame is equal to 255 or 0.

[0167] In a possible case, the grayscale value of the first test frame is greater than the grayscale value of the second test frame, and the fifth pixel grayscale value is equal to the grayscale value threshold parameter; after the timing controller determines that the grayscale value of the first test frame is switched to the fifth pixel grayscale value corresponding to the grayscale value of the second test frame, the processing device switches the grayscale value of the second test frame to the pixel grayscale value corresponding to the grayscale value of the second test frame, which is used to display the second test frame.

[0168] Based on the generation system provided in any of the foregoing designs, the signal acquisition device in the generation system can acquire a luminance change waveform of the display panel displaying the plurality of test frames; and the processing device can adjust, based on the luminance change waveform, the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship.

[0169] In the embodiments of the present application, the process of the timing controller driving the plurality of test frames can refer to the driving method of the display panel provided in the foregoing embodiments, which will not be described here again.

[0170] In the process of the processing device adjusting, based on the luminance change waveform, the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship, the processing device can detect the time corresponding to the maximum amplitude in the luminance change waveform in real time.

[0171] In some examples, if the first time corresponding to the maximum amplitude in the luminance change waveform is before the predetermined stable time, and the maximum amplitude is greater than the amplitude corresponding to the stable time, the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship is increased.

[0172] Please refer to Figure 12 , curve 0 is a luminance change curve without overdrive. In the luminance change waveform shown in curve 1, the time t1_1 corresponding to the maximum amplitude is before the stable time tn, and the maximum amplitude is greater than the amplitude corresponding to the stable time, which can reflect that there is still overdrive. The stable time tn is pre-configured. The processing device can increase the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship. Optionally, the amount of increase can be configured according to the actual application scenario.

[0173] In other examples, if the amplitude at each time before the stable time in the luminance change waveform is less than the amplitude corresponding to the stable time, the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship is decreased.

[0174] Please refer to Figure 12 , curve 0 is a luminance change curve without overdrive. In the luminance change waveform shown in curve 2, the amplitude at each time before the stable time tn is less than the amplitude corresponding to the stable time, which can reflect that there is underdrive. The processing device can decrease the overdrive gray scale value corresponding to the switching of the gray scale value of the second test frame to the gray scale value of the third test frame in the query driving relationship. Optionally, the amount of decrease can be configured according to the actual application scenario.

[0175] In some examples, the processing device can send the adjusted query-driven relationship to the timing controller. In other examples, the processing device can send a modification instruction to the timing controller to cause the timing controller to make the same modification to the query-driven relationship.

[0176] Based on the generation system provided in the above embodiments, an embodiment of the present application provides a determination method of a driving relationship, which can be executed by the generation system.

[0181] In addition, an embodiment of the present application further provides a determination method of a driving relationship, which can be applied to the structure of the generation system as shown in Figure 10 or Figure 11 The determination method of the driving relationship can include the following steps: Figure 14

[0182] ​S1401, determine, based on the execution driving relationship, a pixel gray scale value corresponding to a gray scale value of the second test frame, from a gray scale value of the first test frame, the execution driving relationship comprising switching a starting gray scale value to a pixel gray scale value corresponding to a target gray scale value, the pixel gray scale value being used to display the target gray scale value, the starting gray scale value being any one of a plurality of preset gray scale values, the target gray scale value being any one of the plurality of gray scale values, wherein the gray scale value of the first test frame is any one of the plurality of gray scale values, and the gray scale value of the second test frame is any one of the plurality of gray scale values.

[0183] S1402, collect a luminance change waveform of the display panel displaying the first test frame and the second test frame.

[0184] S1403, determine, based on the luminance change waveform, a gray scale value corresponding to a frame end time as an over gray scale value corresponding to the gray scale value of the second test frame, from the gray scale value of the first test frame, in a query driving relationship.

[0185] The determination method of the driving relationship provided by the embodiment of the application will be described below in combination with the structure of the generation system.

[0186] In a possible design, before step S1401, the processing apparatus can send a gray scale switching instruction to the timing controller, the gray scale switching instruction being used to indicate switching from the gray scale value of the first test frame to the gray scale value of the second test frame.

[0187] The timing controller can determine, according to the execution driving relationship, a pixel gray scale value corresponding to the gray scale value of the second test frame, from the gray scale value of the first test frame, and drive the second test frame.

[0188] The signal collection apparatus can collect a luminance change waveform of the display panel in the process of switching from the first test frame to the second test frame.

[0189] The processing apparatus can sample the luminance change waveform at a preset sampling rate QN. As shown in FIG. 6, the luminance change waveform and the sampling points are shown. In some examples, the relationship between the luminance and the gray scale value can be as follows: Figure 15 wherein Lm represents any one of the luminance values, and GrayQN represents the gray scale value corresponding to Lm. Based on the corresponding relationship between the luminance and the gray scale value, the processing apparatus can determine the gray scale values corresponding to the plurality of sampling points in the process of switching from the first test frame to the second test frame. Optionally, as shown in FIG. 7, the gray scale values corresponding to the plurality of sampling points in the process of switching from the first test frame to the second test frame can be stored in the form of a table. Figure 16

[0190] ​​The processing device can determine a frame time tm of the display panel in advance. For example, assuming that the refresh rate of the display panel is 60 Hz, the processing device can determine that the frame time of the display panel is 1 / 60 = 16.7 ms. In the process of switching the first test frame to the second test frame, the gray scale value corresponding to the frame time tm in the order of time from small to large is determined as the over gray scale value corresponding to the switching of the gray scale value of the first test frame to the gray scale value of the second test frame in the query driving relationship.

[0191] In some examples, the processing device can traverse each starting gray scale value to switch to each target gray scale value in the driving relationship, generate a plurality of gray scale switching instructions, and send the gray scale switching instructions to the timing controller. In other examples, the processing device can select the gray scale value of the first test frame and the gray scale value of the second test frame from the driving relationship, and the gray scale value of the first test frame and the gray scale value of the second test frame satisfy the following conditions: in the driving relationship, the pixel gray scale value corresponding to the switching of the gray scale value of the first test frame to the gray scale value of the second test frame is 255, or the pixel gray scale value corresponding to the switching of the gray scale value of the first test frame to the gray scale value of the second test frame is 0.

[0192] After determining the over gray scale value corresponding to the switching of the gray scale value of one test frame to the gray scale value of another test frame, the processing device can send the next gray scale switching instruction to the timing controller. The process of determining the over gray scale value in the query driving relationship based on the collected luminance change waveform is repeated.

[0193] Optionally, the processing device can send the finally determined query driving relationship to the timing controller. Alternatively, the processing device can send a modification instruction to the timing controller to modify the corresponding over gray scale value in the query driving relationship in the memory after determining each over gray scale value.
