[0032] According to another aspect of the present invention, a debugging device for a display panel is provided. The debugging device includes: a first actual brightness acquisition module, configured to acquire, at the first frame refresh frequency, the first actual display brightness respectively corresponding to multiple different first preset driving data when driving the display panel to display a picture with the multiple different first preset driving data;

[0033] A second actual brightness acquisition module, configured to acquire, at the second frame refresh frequency, the second actual display brightness respectively corresponding to the multiple different first preset driving data when driving the display panel to display a picture with the multiple different first preset driving data;

That is, the actual display brightnesses of the first frame refresh rate and the second frame refresh rate at the same preset brightness are close or equal. It can be seen that through the debugging method for the display panel provided in this embodiment, the brightness difference between display screens can be made small when the display panel switches between different frame refresh rates, thereby avoiding the flashing screen phenomenon.

Obviously, the following drawings are only some embodiments of the present invention.

[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0045] As mentioned in the background art, there will be a flash screen problem when the existing display panel switches between different frame refresh rates. To solve the flash screen problem, generally the following two solutions are adopted in the prior art: One solution is to perform gamma debugging at a frame refresh rate between two adjacent frame refresh rates of the display panel to obtain a set of driving data, and both of the adjacent two frame refresh rates use this set of driving data for display. Since the leakage at a low frame refresh rate is more serious than that at a high frame refresh rate, there will still be a flash screen problem when using a set of driving data for driving. Another solution is to perform gamma debugging separately for each frame refresh rate to obtain corresponding driving data, and each frame refresh rate uses the corresponding driving data for display. In this way, although the flash screen problem can be solved, a set of driving data needs to be debugged for each frame refresh rate, and the debugging time is too long, which affects the debugging efficiency.

[0046] To improve the debugging efficiency and solve the splash screen problem, this embodiment provides a debugging method for a display panel. Figure 1 It is a schematic flowchart of a debugging method for a display panel provided according to an embodiment of the present invention. Refer to Figure 1 The debugging method provided in this embodiment includes the following steps:

[0047] S110. Obtain the first actual display brightness corresponding to each of a plurality of different first preset driving data when driving the display panel to display a picture at the first picture refresh rate.

[0048] Specifically, the first picture refresh rate can be 60Hz, 90Hz, 120Hz, etc. The first preset driving data can be the driving data corresponding to a plurality of preset brightness levels determined by performing gamma debugging on the display panel at a preset picture refresh rate. The preset picture refresh rate can be equal to the first picture refresh rate, or can be greater than the first picture refresh rate and less than the second picture refresh rate. When the first preset driving data is different, the first actual display brightness of the display panel is different, and the first preset driving data and the first actual display brightness are in one-to-one correspondence.

[0049] S120. Obtain the second actual display brightness corresponding to each of a plurality of different first preset driving data when driving the display panel to display a picture at the second picture refresh rate.

[0050] Specifically, the first picture refresh rate and the second picture refresh rate can be the most frequently used picture refresh rates of the display panel. The second picture refresh rate can be 60Hz, 90Hz, 120Hz, etc. The second picture refresh rate is different from the first picture refresh rate. When driving the display panel to display at the second picture refresh rate using the first preset driving data, different first preset driving data correspond to different second actual display brightness, and the first preset driving data and the second actual display brightness are in one-to-one correspondence.

[0051] S130. Determine the second preset driving data corresponding to at least two different first actual display brightness levels when displaying at the second picture refresh rate according to the correspondence between the first preset driving data and the second actual display brightness.

[0052] Specifically, first determine at least two first actual display brightnesses as target brightnesses. Among multiple second actual display brightnesses at the second frame refresh frequency, find the second actual display brightnesses that are respectively close to or equal to the at least two first actual display brightnesses, and use the first preset driving data corresponding to these second actual display brightnesses as the second preset driving data. Exemplarily, Table 1 is a correspondence table of the first preset driving data, the first actual display brightness, and the second actual display brightness. Referring to Table 1, each first preset driving data in Table 1 corresponds to a first actual display brightness and a second actual display brightness respectively. The at least two different first actual display brightnesses may include A1 and A4. B2 among the second actual display brightnesses is equal to or closest to A1 among the first actual display brightnesses, and B6 among the second actual display brightnesses is equal to or closest to A4 among the first actual display brightnesses. Then, the first preset driving data D2 corresponding to B2 among the second actual display brightnesses is the second preset driving data for displaying the first actual display brightness at the second frame refresh frequency, and the first preset driving data D6 corresponding to B6 among the second actual display brightnesses is the second preset driving data for displaying the first actual display brightness at the second frame refresh frequency. The second preset driving data corresponding to other first actual display brightnesses can be obtained by interpolation based on D2 and D6.

[0053] Table 1

[0054]

[0055] S140. Determine the first driving data corresponding to multiple preset brightnesses of the display panel at the first frame refresh frequency according to the correspondence between the first actual display brightness and the first preset driving data, and determine the second driving data corresponding to multiple preset brightnesses of the display panel at the second frame refresh frequency according to the correspondence between the first actual display brightness and the second preset driving data.

[0056] Specifically, the preset brightness may be the brightness corresponding to the gamma calibration binding points of the display panel. Among the first actual display brightnesses, find the first actual display brightnesses that are closest to the preset brightness. The first preset driving data corresponding to these first actual display brightnesses are the first driving data, and the second preset driving data corresponding to these first actual display brightnesses are the second driving data. Exemplarily, referring to Table 1, the first driving data corresponding to the preset brightnesses L1 - L6 are D1 - D6 respectively, the second driving data corresponding to the preset brightness L1 is D2, and the second driving data corresponding to the preset brightness L4 is D6.

[0057] At the same preset brightness, the actual display brightness at the first frame refresh frequency is the first actual display brightness, and the actual display brightness at the second frame refresh frequency is the same first actual display brightness, or close to the first actual display brightness. That is, the actual display brightnesses at the first and second frame refresh frequencies are close or equal at the same preset brightness. Therefore, the solution of this embodiment can reduce the brightness difference between different frame refresh frequencies and avoid the flashing phenomenon of the display panel. In addition, in this embodiment, only one set of first preset driving data can reduce the brightness difference of the display panel at different frame refresh frequencies. Debugging one set of first preset driving data can shorten the debugging time.

[0058] The debugging method of the display panel provided in this embodiment uses multiple first preset driving data to drive the display panel at the first frame refresh frequency to obtain the first actual display brightness corresponding to the first preset driving data. At the second frame refresh frequency, multiple first preset driving data are used to drive the display panel to obtain the second actual display brightness corresponding to the first preset driving data. According to the correspondence between the first preset driving data and the second actual display brightness, the second preset driving data corresponding to at least two different first actual display brightnesses when using the second frame refresh frequency to display is determined. Finally, according to the correspondence between the first actual display brightness and the first preset driving data, the first driving data corresponding to multiple preset brightnesses of the display panel at the first frame refresh frequency is determined. According to the correspondence between the first actual display brightness and the second preset driving data, the second driving data corresponding to multiple preset brightnesses of the display panel at the second frame refresh frequency is determined. That is, one preset brightness corresponds to one first actual display brightness. The first preset driving data corresponding to the first actual display brightness is the first driving data, and the corresponding second preset driving data is the second driving data. The actual display brightness of the first preset driving data corresponding to the same first actual display brightness is the first actual display brightness, and the actual display brightness of the corresponding second preset driving data is the first actual display brightness or close to the first actual display brightness. Therefore, in this embodiment, at the same preset brightness, the actual display brightness of the first frame refresh frequency driven by the first driving data is the first actual display brightness, and the actual display brightness of the second frame refresh frequency driven by the second driving data is the same first actual display brightness, or close to the first actual display brightness. That is, the actual display brightnesses at the first and second frame refresh frequencies are close or equal at the same preset brightness. It can be seen that through the debugging method of the display panel provided in this embodiment, when the display panel switches between different frame refresh frequencies, the brightness difference between the display screens is small, thus avoiding the flashing phenomenon.

[0059] Optionally, after obtaining the first actual display brightness corresponding to each of the multiple first preset driving data when driving a display panel to display a picture at a first picture refresh rate, the method further includes:

[0060] Obtaining the n-th actual display brightness corresponding to each of the multiple first preset driving data when driving the display panel to display a picture at an n-th picture refresh rate;

[0061] Determining the n-th preset driving data corresponding to each of at least two different first actual display brightnesses when using the n-th picture refresh rate to display according to the correspondence between the first preset driving data and the n-th actual display brightness; where n is an integer greater than or equal to 3;

[0062] Determining the n-th driving data for the display panel to display multiple preset brightnesses at the n-th picture refresh rate according to the correspondence between the first actual brightness and the n-th preset driving data.

[0063] Specifically, the first picture refresh rate may be the most frequently used picture refresh rate of the display panel. The display panel will display pictures at multiple different picture refresh rates. To avoid the screen flashing phenomenon when the display panel switches between different picture refresh rates, the debugging method provided in this embodiment is based on the first picture refresh rate, determines the n-th preset driving data at the n-th picture refresh rate according to the first actual display brightness at the first picture refresh rate, and then determines the n-th driving data according to the correspondence between the n-th preset driving data and the first actual display brightness. The specific determination method is the same as the method for determining the second preset driving data and the second driving data. Exemplarily, at the third picture refresh rate, use the first preset driving data to drive the display panel to display. Different first preset driving data correspond to different third actual display brightnesses, and the first preset driving data and the third actual display brightness are in one-to-one correspondence. Then, determine at least two first actual display brightnesses as target brightnesses among the first actual display brightnesses, find the third actual display brightnesses that are respectively close to or equal to the at least two first actual display brightnesses among the multiple third actual display brightnesses at the third picture refresh rate, and use the first preset driving data corresponding to these third actual display brightnesses as the third preset driving data. At the same preset brightness, use the third preset driving data corresponding to the first actual display brightness as the third driving data. The determined third driving data can make the actual brightness of the display panel driven by the third driving data at the third picture refresh rate close to or equal to the actual brightness of the display panel driven by the first driving data at the first picture refresh rate at the same preset brightness, so that there is no screen flashing phenomenon when the display panel switches from the first picture refresh rate to the third picture refresh rate.

[0064] By using the method of this embodiment, at the same preset brightness, the actual display brightness at the picture refresh frequencies other than the first picture refresh frequency is close to or equal to the first actual display brightness at the first picture refresh frequency, thereby reducing the difference in actual display brightness when switching from the first picture refresh frequency to any picture refresh frequency, and reducing the difference in actual display brightness when switching between any two picture refresh frequencies, thereby avoiding the phenomenon of screen flashing on the display panel.

[0065] In addition, the nth driving data for the nth picture refresh frequency can also be determined in the following manner:

[0066] Optionally, after determining the corresponding second preset driving data when displaying at least two different first actual display brightnesses using the second picture refresh frequency according to the correspondence between the first preset driving data and the second actual display brightness, it further includes:

[0067] Obtain the nth actual display brightness corresponding to each of the multiple different (n - 1)th preset driving data when driving the display panel to display a picture with the multiple different (n - 1)th preset driving data at the nth picture refresh frequency;

[0068] Determine the corresponding nth preset driving data when displaying at least two (n - 1)th actual brightnesses using the nth picture refresh frequency according to the correspondence between the (n - 1)th preset driving data and the nth actual display brightness, where n is an integer greater than or equal to 3;

[0069] Determine the nth driving data for the display panel to display multiple preset brightnesses at the nth picture refresh frequency according to the correspondence between the (n - 1)th actual brightness and the nth preset driving data.

[0070] Specifically, the refresh frequency of the (n - 1)th frame and the refresh frequency of the nth frame can be two adjacent frame refresh frequencies in the display panel, or two frame refresh frequencies with a relatively high switching frequency in the display panel. After determining the correspondence between the actual display brightness of the (n - 1)th frame and the (n - 1)th preset driving data at the refresh frequency of the (n - 1)th frame, and after determining the actual display brightness of the nth frame at the refresh frequency of the nth frame, at least two actual display brightness values of the (n - 1)th frame can be determined as target brightness values. Then, from the actual display brightness values of the nth frame, the actual display brightness values of the nth frame that are close to or equal to the at least two actual display brightness values of the (n - 1)th frame are found. The (n - 1)th preset driving data corresponding to these actual display brightness values of the nth frame is the nth preset driving data, thereby determining the nth preset driving data corresponding to each actual display brightness value of the (n - 1)th frame. The same preset brightness corresponds to the same actual display brightness value of the (n - 1)th frame. The (n - 1)th preset driving data corresponding to this actual display brightness value of the (n - 1)th frame is the (n - 1)th driving data, and the nth preset driving data corresponding to this actual display brightness value of the (n - 1)th frame is the nth driving data. Therefore, when displaying the same preset brightness, the actual display brightness when driving the display panel with the nth driving data at the refresh frequency of the nth frame is equal to or close to the corresponding actual display brightness value of the (n - 1)th frame, and the actual display brightness when driving the display panel with the (n - 1)th driving data at the refresh frequency of the (n - 1)th frame is equal to the actual display brightness value of the (n - 1)th frame. That is, the actual display brightness at the refresh frequencies of the (n - 1)th frame and the nth frame for the same preset brightness is close to or equal. Such a setting can result in little or no brightness difference in the display screen of the display panel when switching from the refresh frequency of the (n - 1)th frame to the refresh frequency of the nth frame, thereby avoiding the phenomenon of screen flashing.

[0071] It should be noted that in this embodiment, each (n - 1)th preset driving data corresponds to an actual display brightness value of the (n - 2)th frame. The actual display brightness value of the (n - 1)th frame corresponding to each (n - 1)th preset driving data is close to or equal to the actual display brightness value of the (n - 2)th frame corresponding to it. That is, for the same preset brightness, the difference in actual display brightness among the refresh frequencies of the (n - 2)th frame, the (n - 1)th frame, and the nth frame is small, thereby avoiding the phenomenon of screen flashing.

[0072] Exemplarily, a second actual display brightness equal to or close to the at least two first actual display brightnesses is determined according to the at least two first actual display brightnesses, and the first preset driving data corresponding to the second actual display brightness is determined as the second preset driving data. Then, one second preset driving data corresponds to one first actual display brightness and one second actual display brightness, and the second actual display brightness is equal to or close to the first actual display brightness. At the third frame refresh rate, the display panel is driven with the second preset driving data to obtain a third actual display brightness. The at least two second actual display brightnesses are determined as the target brightnesses, and the third actual display brightnesses that are respectively close to the at least two second actual display brightnesses are found from the third actual display brightnesses, so as to determine the third preset driving data. In this way, the difference between each second actual display brightness and the corresponding third actual display brightness and the corresponding first actual display brightness is small, that is, at the same preset brightness, the difference between the actual display brightnesses corresponding to different frame refresh rates is small, avoiding the phenomenon of screen flashing.

[0073] Optionally, determining the second preset driving data corresponding to at least two different first actual display brightnesses when using the second frame refresh rate according to the correspondence between the first preset driving data and the second actual display brightness includes:

[0074] Determining the first preset driving data corresponding to the second actual display brightness closest to the first actual display brightness as the second preset driving data corresponding to the first actual display brightness when displayed at the second frame refresh rate.

[0075] Specifically, at least two first actual display brightnesses are found from the multiple first actual display brightnesses as the target brightnesses, and the second actual display brightnesses closest to the corresponding target brightnesses are found from the second actual display brightnesses. Such a setting can make the second actual display brightness at the same preset brightness equal to or close to the first actual display brightness when the display panel switches from the first frame refresh rate to the second frame refresh rate, thereby reducing the difference in display brightness when switching between different frame refresh rates and avoiding the phenomenon of screen flashing on the display panel.

[0076] Optionally, after determining the second preset driving data corresponding to at least two different first actual display brightnesses when using the second frame refresh rate according to the correspondence between the first preset driving data and the second actual display brightness, it further includes:

[0077] According to the second preset driving data corresponding to at least two different first actual display brightnesses, an interpolation algorithm is used to determine the second preset driving data corresponding to other first actual display brightnesses.

[0078] Specifically, continuing to refer to Table 1, it can be seen from Table 1 that the second preset driving data corresponding to A2, A3, A5, and A6 have not been determined yet. The second preset driving data corresponding to A2, A3, A5, and A6 can be determined by linear interpolation based on A1, A2, A3, A4, A5, A6, D2, and D6. Exemplarily, it is assumed that there is a linear relationship between the first actual display brightness and the second preset driving data. That is, after determining the linear function relationship based on (A1, D2) and (A4, D6), the second preset driving data corresponding to A2 is obtained according to A2, the second preset driving data corresponding to A3 is obtained according to A3, the second preset driving data corresponding to A5 is obtained according to A5, and the second preset driving data corresponding to A6 is obtained according to A6.

[0079] Optionally, before obtaining the first actual display brightness corresponding to multiple different first preset driving data when driving the display panel to display a picture at the first frame refresh rate, it further includes:

[0080] Obtaining the driving data when the actual display brightness when displaying a preset brightness at the first frame refresh rate conforms to the first set tolerance and the actual display chromaticity when displaying the preset brightness at the first frame refresh rate satisfies the second set tolerance with the first target chromaticity, and determining the driving data at this time as the first preset driving data.

[0081] Specifically, the actual display brightness conforming to the first set tolerance with the preset brightness means that the difference between the actual display brightness and the preset brightness is within the range of the first set tolerance, and the actual display chromaticity satisfying the second set tolerance with the first target chromaticity means that the difference between the actual display chromaticity and the first target chromaticity is within the range of the second set tolerance. Determining the first preset driving data according to the first frame refresh rate can make the first actual display brightness closer to the preset brightness. Since the actual display brightness at other frame refresh rates is close to the first actual display brightness, when driving the display panel to display using the finally determined first driving data, second driving data... nth driving data respectively, the display brightness of the display panel is closer to the preset brightness, and the display effect of the display panel is better. The debugging method of the display panel provided in this embodiment can shorten the debugging time and improve the debugging efficiency while ensuring that the actual display brightness at multiple different frame refresh rates is close to the preset brightness and improving the display effect, and only needs to debug a set of preset driving data.

[0082] Optionally, obtaining the driving data when the actual display brightness when displaying a preset brightness at the first frame refresh rate conforms to the first set tolerance and the actual display chromaticity when displaying the preset brightness at the first frame refresh rate satisfies the second set tolerance with the first target chromaticity, and determining the driving data at this time as the first preset driving data, includes:

[0083] When it is determined that the display panel displays the screen at the first screen refresh frequency, determine the first preset driving data corresponding to at least two different brightness modes respectively, where, under the same brightness mode, the first preset driving data corresponding to at least two different preset brightnesses is included, the minimum display brightnesses of different brightness modes are the same, and the maximum display brightnesses of different brightness modes are different.

[0084] Optionally, determine the first driving data corresponding to multiple preset brightnesses of the display panel at the first screen refresh frequency according to the correspondence between the first actual display brightness and the first preset driving data, and determine the second driving data corresponding to multiple preset brightnesses of the display panel at the second screen refresh frequency according to the correspondence between the first actual display brightness and the second preset driving data, including:

[0085] Determine the first driving data corresponding to multiple preset brightnesses of the display panel in multiple different brightness modes at the first screen refresh frequency according to the correspondence between the first actual display brightness and the first preset driving data, and determine the second driving data corresponding to multiple preset brightnesses of the display panel in multiple different brightness modes at the second screen refresh frequency according to the correspondence between the first actual display brightness and the second preset driving data.

[0086] Specifically, the brightness range of the brightness mode can be 0-10 nit, 0-20 nit, 0-30 nit, 0-100 nit, 0-500 nit, etc. The brightness range of each brightness mode can be divided into 2 n gray scale levels. Exemplarily, each brightness mode can be divided into 0-255 gray scales. At least two different gamma adjustment binding points can be set under each brightness mode, and each gamma adjustment binding point corresponds to a preset brightness (or preset gray scale). Exemplarily, each brightness mode can respectively select 255 gray scale, 128 gray scale or 64 gray scale, etc. as the gamma adjustment binding points. After setting at least two different gamma adjustment binding points under each brightness mode and determining the first preset driving data corresponding to the at least two gamma adjustment binding points, adjust the correspondence between the actual display brightness of different screen refresh frequencies and the driving data according to the first preset driving data. Finally, after determining the driving data corresponding to each gamma adjustment binding point at each screen refresh frequency, interpolation can be performed through the at least two gamma adjustment binding points to determine the driving data corresponding to other gray scales, so as to reduce the number of binding points, reduce the adjustment time, and ensure that the driving data of each gray scale under each brightness mode is relatively accurate. Exemplarily, continue to refer to Table 1. The preset brightnesses L1, L2, L3, L4, L5, L6 in Table 1 can represent multiple preset brightnesses corresponding to the same brightness mode, and the first driving data corresponding to other preset brightnesses in the same brightness mode can be obtained by interpolation through the multiple preset brightnesses and the first driving data corresponding to the multiple preset brightnesses.

[0087] Optionally, determine the first driving data corresponding to multiple preset brightnesses of the display panel in multiple different brightness modes at the first frame refresh rate according to the correspondence between the first actual display brightness and the first preset driving data, and determine the second driving data corresponding to multiple preset brightnesses of the display panel in multiple different brightness modes at the second frame refresh rate according to the correspondence between the first actual display brightness and the second preset driving data, including: determining the driving data of multiple preset brightnesses in all brightness modes by using an interpolation algorithm.

[0088] Specifically, the interpolation algorithm can be a user-defined interpolation algorithm. Exemplarily, at the second frame refresh rate, after the first driving data of the brightness mode with a brightness range of 0-10 nit and the first driving data of the brightness mode with a brightness range of 0-30 nit are determined, the first driving data of the brightness mode with a brightness range of 0-20 nit can be obtained by using the interpolation algorithm based on the first driving data of the brightness range of 0-10 nit and the first driving data of the brightness range of 0-30 nit.

[0089] The following further explains the debugging method provided in this embodiment with reference to Table 2. Referring to Table 2, a 51 value in Table 2 corresponds to a brightness mode, and the first column and the fifth column in Table 2 represent the 51 values. The brightness corresponding to a 51 value in Table 2 is the actual display brightness corresponding to the 255 gray level in this brightness mode, and the brightness corresponding to other gray levels is not shown in Table 2. The first frame refresh rate in Table 2 is 60 Hz, and the second frame refresh rate is 90 Hz. The second column and the sixth column in Table 2 represent the first actual display brightness driven by the first preset driving data at the first frame refresh rate. The first preset driving data in Table 2 is a set of driving data obtained by gamma debugging at a frame refresh rate of 72 Hz. The third column and the seventh column in Table 2 represent the second actual display brightness driven by the first preset driving data at the second frame refresh rate. In the first actual display brightness, 674.723 corresponding to the 51 value of 4095 and 493.0199 corresponding to the 51 value of 3515 are used as the target brightnesses. The brightness value closest to 674.723 is found in the second actual display brightness, which is 674.4757. The first preset driving data corresponding to 674.4757 is used as the second preset driving data corresponding to the display brightness of 674.723 at the second frame refresh rate. The same method is used to find the brightness value closest to 493.0199 in the second actual display brightness, which is 493.096. The first preset driving data corresponding to 493.096 is used as the second preset driving data corresponding to the display brightness of 493.0199 at the second frame refresh rate.

[0090] The 4th column and the 8th column in Table 2 represent the remapped second actual display brightness corresponding to the second preset driving data at the second screen refresh frequency. It should be noted that in this embodiment, the remapped second actual display brightness is the second actual display brightness corresponding to the first actual display brightness in the same row. After the second preset driving data and the remapped second actual display brightness when the 51 value is 4095, and the second preset driving data and the remapped second actual display brightness when the 51 value is 3515 are determined, the remapped second actual display brightness between the 51 values of 4094 to 3516 is determined according to the linear interpolation algorithm, and thus the corresponding second preset driving data is determined according to the remapped second actual display brightness. The specific method includes the following steps:

[0091] Figure 2 is a corresponding relationship diagram of the actual display brightness corresponding to different 51 values and 255 gray levels. Refer to Figure 2 , Figure 2 in which the abscissa represents the 51 value, that is, the brightness mode, Figure 2 and the ordinate in

[0097] Figure 3It is a test result graph of using the prior art debugging method and the debugging method provided by the embodiments of the present invention. Table 3 is a comparison table of the brightness differences corresponding to the first frame refresh frequency and the second frame refresh frequency before remapping and the brightness differences corresponding to the first frame refresh frequency and the second frame refresh frequency after remapping. Figure 3 Corresponding to Table 3, Figure 3 the original difference in Figure 3 represents the difference between the first actual display brightness and the second actual display brightness, corresponding to the data in the second column of Table 3.

[0099] Specifically, the greater the frame refresh frequency, the higher the corresponding actual display brightness in the same brightness mode. Therefore, in the same brightness mode, the actual display brightness with a larger frame refresh frequency can be found from the actual display brightness with a smaller frame refresh frequency, so as to facilitate determining the second preset driving data and the nth preset driving data. By adjusting the correspondence between the driving data of the larger frame refresh frequency and the preset brightness with the smaller frame refresh frequency as the brightness reference, the algorithm is simpler.
