[0022] As Figure 1 shown, a method for driving an organic electroluminescent panel in a partitioned dynamic manner in a preferred embodiment of an embodiment of the present application includes: S101: Establish a plurality of operating sub-regions according to the device parameters of the organic electroluminescent panel; S102: Set a primary driving strategy for each operating sub-region according to the data to be displayed, and determine whether to generate a compensation instruction according to the display requirement value of each operating sub-region; S103: Obtain the monitoring data packets of each operating sub-region according to the preset monitoring time nodes, and determine whether to generate a correction instruction according to all the monitoring data packets; Among them, when establishing a plurality of operating sub-regions, it includes: Set the sequence of operating sub - regions A, A=(a1, a2…a i …a n ), where a i is the i - th operating sub - region; n is the number of operating sub - regions.

[0023] Specifically, according to the device parameters of the organic electroluminescent panel, it is divided into multiple physically independent regions, so as to set multiple operating sub - regions, and several pixels are included in a single operating sub - region.

[0024] Specifically, when setting the primary driving strategy for each operating sub - region, it includes: Set multiple display evaluation indicators according to historical display data, and establish a driving strategy library based on all display evaluation indicators; Set a i as the target sub - region in sequence according to the sequence of operating sub - regions A; Generate a display requirement package for the target sub - region according to the pre - processing result of the data to be displayed; Set the primary driving strategy for the target sub - region according to the display requirement package and the driving strategy library; Set the primary driving strategy for each operating sub - region in sequence; Establish a sequence of primary driving strategies P, P=(p1, p2…p i …p n ), where p i is the i - th primary driving strategy; n is the number of primary driving strategies.

[0025] Specifically, the data to be displayed refers to the image content that the organic electroluminescent panel needs to display within a certain adjustment period. The required display image content of each operating sub - region is cut through an image analysis model, so as to generate a display requirement package for each operating sub - region.

[0026] Specifically, set multiple display evaluation indicators according to historical display data, quantify each display evaluation indicator and then construct multiple display requirement scenarios, and set the driving sub - strategies corresponding to each display requirement scenario according to historical display data.

[0027] Specifically, the display evaluation indicators include but are not limited to brightness change, gray - scale change, whether it is a highlighted area (such as a subtitle area, a light source area, etc.), whether the display content is static or dynamic content, etc.

[0028] Specifically, the driving sub - strategies include parameters such as the driving circuit of the current region, pixel voltage, refresh rate, PWM duty cycle, etc.

[0029] Specifically, a driving policy library is constructed according to all driving sub-policies, and by analyzing the display requirement packages of each operation sub-region, the real-time reference values of each display evaluation index are determined to determine the corresponding display requirement scenarios, and the corresponding driving sub-policies are called as the primary driving policies for the operation sub-regions.

[0030] It can be understood that in the above embodiments, the device parameters of the organic electroluminescent panel divide the entire display panel into multiple physically or logically independent regions, and set independent driving circuits for each partition. By analyzing the real-time data to be displayed, the display requirements of each partition are generated, so as to dynamically optimize the driving parameters, reduce the overall operation loss, and improve the service life of the organic electroluminescent panel.

[0031] In the preferred embodiment of the present application, when determining whether to generate a compensation instruction, it includes: Establish an associated mapping table according to the position parameters of each operation sub-region; Set a i as the target sub-region in sequence according to the operation sub-region sequence A; Generate the display requirement value b of the target sub-region; Set the display requirement values of each operation sub-region in sequence, and establish a display requirement value sequence B, B = (b1, b2... b i ... b n ), where b i is the display requirement value of the i-th operation sub-region; Generate a compensation evaluation value w according to the display requirement value sequence B; Preset a compensation evaluation value threshold W1; If w > W1, generate a primary compensation instruction.

[0032] Specifically, when generating the display requirement value b of the target sub-region, it includes: b = e1 * Q1 * β i *(c i - c' i )] + e2 * Q2 * β i *(c 1i - c' i )] where e1 is a preset first weight coefficient; e2 is a preset second weight coefficient; Q1 is a preset first fixed coefficient; Q2 is a preset second fixed coefficient; θ1 is the number of display evaluation indexes; β i is the influence factor of the i-th display evaluation index; c i is the real-time reference value of the i-th display evaluation index generated based on the display requirement package of the target sub-region; c' iis the standard reference value of the i-th display evaluation index; c 1i It is the first-level reference value of the i-th display evaluation index generated based on the display requirement package of all associated sub-areas of the target sub-area in the association mapping table.

[0033] Specifically, an association mapping table is constructed according to the positional relationship between each operating sub-region, and all adjacent operating sub-regions of the operating sub-region are associated sub-regions of the operating sub-region.

[0034] Specifically, by comprehensively analyzing the target sub-region and adjacent associated sub-regions, the display requirements of the target sub-region are comprehensively evaluated and adjusted in a coordinated manner to avoid brightness penetration at the edges of the sub-regions and ensure the overall display efficiency of the organic electroluminescent panel.

[0035] Specifically, the larger the display demand value is, the greater the overall operating power consumption and driving load of the current operating sub-area during the operation process is.

[0036] Specifically, all parameters in the model are normalized by presetting the first fixed coefficient and the second fixed coefficient, so that each parameter in the model is in the same value range.

[0037] Specifically, when generating the compensation evaluation value w according to the display demand value sequence B, it includes: w=e3*Q3*[ (b i -b') 2 ]+e4*Q4*[ Y(i)*(b i -B1)]; Wherein, e3 is the preset third weight coefficient; e4 is the preset fourth weight coefficient; Q3 is the preset third fixed coefficient; Q4 is the preset fourth fixed coefficient; b' is the average value of all data in the display demand value series B; B1 is the preset first display demand value threshold; Y(i) is the selection coefficient; if (b i -B1)<0,Y(i)=1 / (b i -B1); if (b i -B1)>0,Y(i)=0.

[0038] Specifically, the larger the compensation evaluation value is, the worse the display uniformity of the current organic electroluminescent panel is, and the greater the possibility of brightness penetration between the edges of adjacent operating sub-areas is.

[0039] Specifically, all parameters in the model are normalized by presetting the third fixed coefficient and the fourth fixed coefficient, so that each parameter in the model is in the same value range.

[0040] Specifically, the first-level compensation orders include: A first display requirement value threshold B1 and a second display requirement value threshold B2 are preset, and B1 <B2; If b i <B1,设定第i个运行子区域为一级子区域; If B1 i <B2,设定第i个运行子区域为二级子区域; If b i >B2, set the i-th operating sub-area as a third-level sub-area; According to all the first-level sub-areas, establish the first-level sub-area sequence A1, A1=(a 11 ,a 12 …a 1i …a 1n1 ), where a 1i is the i-th first-level sub-region, n1 is the number of first-level sub-regions; Set the first-level compensation strategy according to the first-level sub-area sequence A1; According to all the three-level sub-areas, a three-level sub-area sequence A3 is established, A3=(a 31 ,a 32 …a 3i …a 3n3 ), where a 3i is the i-th third-level sub-region, n3 is the number of third-level sub-regions; A secondary compensation strategy is generated according to the third-level sub-region sequence A3.

[0041] Specifically, the first display requirement value threshold and the second display requirement value threshold may be set according to historical parameters.

[0042] Specifically, the first-level sub-area is a static area or a low-brightness area. By setting a first-level compensation strategy, the display brightness and refresh rate of each first-level sub-area are reduced in turn based on the original driving parameters to further improve the contrast and reduce overall power consumption.

[0043] Specifically, the secondary sub-area is the normal operating area, and the corresponding primary driving strategy can be executed.

[0044] Specifically, the third-level sub-area is a dynamic area or a high-brightness area. By analyzing the display content of each third-level sub-area, it is determined whether a partition rotation can be performed, that is, the display content of the current third-level sub-area is divided into the first-level sub-area or the second-level sub-area by time period (for example, the subtitles are displayed in different areas to reduce the highlight duration of a single operating sub-area), thereby generating a second-level compensation strategy. Improve the display uniformity of the organic electroluminescent panel, prevent screen burn-in, and increase the overall operating life.

[0045] ​It can be understood that in the above embodiments, by generating the display demand values of each operating sub-region, grading each partition, and dynamically adjusting the corresponding compensation strategy according to the different levels of each operating sub-region, the overall operating power consumption is reduced, the load uniformity of the entire organic electroluminescent panel is ensured, and screen burn and overheating of some regions are prevented. Ensure the safe operation of the organic electroluminescent panel.

[0046] In a preferred embodiment of the present application, when determining whether to generate a correction instruction based on all monitored data packets, it includes: Set a i as the i-th sub-region to be evaluated in sequence according to the operating sub-region sequence A; Obtain the monitored data packet of the sub-region to be evaluated at the current feedback time node; Generate the operating load value f of the sub-region to be evaluated; f = η i *h i ; where θ2 is the number of operating evaluation indicators; η i is the influence factor of the i-th operating evaluation indicator; h i is the reference value of the i-th operating evaluation indicator in the sub-region to be evaluated; Generate the operating load values of each sub-region to be evaluated in sequence; Establish an operating load value sequence F at the current feedback time node, F = (f1, f2... f i ... f n ), where f i is the operating load value of the i-th operating sub-region at the current feedback time node; Generate a correction evaluation value d at the current feedback time node according to the operating load value sequence F; Preset a correction evaluation value threshold D1; If d > D1, generate a first-level correction instruction at the current feedback time node.

[0047] Specifically, the correction evaluation value threshold can be set according to historical parameters.

[0048] Specifically, the operating evaluation indicators include, but are not limited to, multiple parameters such as operating temperature, operating current, operating voltage, operating brightness, and life loss degree of the operating sub-region. The larger the operating load value, the greater the overall operating loss of the current operating sub-region, and potential operating failures may be caused.

[0049] Specifically, when generating the correction evaluation value d, it includes: f = e5 * Q5 * (f i - f') 2+e6*Q6* (f i -F1)]; Among them, e5 is a preset fifth weight coefficient; e6 is a preset sixth weight coefficient; Q5 is a preset fifth fixed coefficient; Q6 is a preset sixth fixed coefficient; f' is the average value of all data in the operating load value sequence F; F1 is a preset first load evaluation value threshold.

[0050] Specifically, the larger the corrected evaluation value is, it indicates that the overall operating loss of the current organic electroluminescent panel is greater, and it is necessary to optimize the driving parameters of each operating sub-region in time to avoid operating failures.

[0051] Specifically, the first load evaluation value threshold can be set according to historical parameters.

[0052] Specifically, according to the first-level correction instruction, the operating sub-regions with operating load values greater than the preset first operating load value threshold are screened, and their driving parameters are dynamically corrected, so as to reduce the overall failure risk of the organic electroluminescent panel and improve the operating life of the electroluminescent panel.

[0053] Specifically, all parameters in the model are normalized by the preset fifth fixed coefficient and the sixth fixed coefficient, so that each parameter in the model is within the same value range.
