Description

Technical Field

[0001] The present invention relates to the field of display control, and particularly to a TFT-LCD liquid crystal display based on intelligent control. Background Art

[0002] The power consumption of TFT-LCD liquid crystal displays is a key evaluation factor in the battery life evaluation process of various mobile terminals. Therefore, the power consumption optimization of TFT-LCD liquid crystal displays has received extensive attention. The reduction of the power consumption of TFT-LCD liquid crystal displays mainly relies on the regulation of the backlight intensity. While reducing the backlight intensity to reduce the display energy consumption, it will affect the picture presentation effect. Therefore, it is necessary to adjust the backlight intensity in real time according to the presented image content. However, if the complexity of the image content is high or the dynamic degree of the image content is large, it is difficult to ensure the overall coordination of the picture and the smoothness of real-time adjustment during the actual real-time adjustment process. Therefore, how to reduce the display energy consumption while ensuring the overall coordination and smoothness of the displayed content during the actual real-time regulation of the backlight is an urgent problem to be solved by those skilled in the art.

[0003] Chinese Patent Publication No. CN101290754A discloses a method for reducing power consumption in a liquid crystal display illuminated by a backlight device, including dimming the backlight and adjusting the image brightness to compensate for the dimmed backlight. A backlight dimming factor is determined according to a clipping point, and the clipping point is determined according to the pixel brightness distribution of the image signal. The image brightness is adjusted according to the dimming factor, where a first image signal mapping function is used to adjust the pixel brightness below the brightness threshold, and a second image signal mapping function is used to adjust the pixel brightness above the brightness threshold. However, the above technical solution has the following defects: It fails to make targeted optimization for the actual regulation process according to the influence of the actual presented picture complexity and picture change situation on the real-time regulation process of the backlight, resulting in a lower overall coordination and smoothness of the presented picture during the real-time regulation process of the backlight. Summary of the Invention

[0004] Therefore, the present invention provides a TFT-LCD liquid crystal display based on intelligent control to overcome the problem in the prior art that it fails to make targeted optimization for the actual regulation process according to the influence of the actual presented picture complexity and picture change situation on the real-time regulation process of the backlight, resulting in a lower overall coordination and smoothness of the presented picture during the real-time regulation process of the backlight.

[0005] To achieve the above object, the present invention provides a TFT-LCD liquid crystal display based on intelligent control, including:

[0006] A display module for receiving an image signal and converting it into a visible image;

[0007] A control and analysis module, connected to the display module, for periodically detecting the display dynamic index and the display complexity index, and determining a regional prediction strategy within a predicted analysis period based on the display dynamic index and the display complexity index. The regional prediction strategy is to set the predicted brightness parameters for each dynamic control region based on a predictive analysis method or a balanced analysis method;

[0008] A prediction processing module, connected to the control and analysis module, for determining a prediction execution method based on the trajectory freedom index and the main control execution dynamic index. The prediction execution method is to determine the prediction key coefficient for each dynamic control region based on the regional key index and the main control execution dynamic index, or to determine the prediction key coefficient for each dynamic control region based on the regional trigger correlation index and the regional key index;

[0011] A balance execution module, connected to the balance processing module, for determining an adjustment execution method based on the execution distribution index and the execution proportion index. The adjustment execution method is to adjust the predicted brightness parameters for each balance processing region based on the reference dynamic change coefficient and the reference prediction difference coefficient, or to determine a balance control set based on the balance overlap parameter.

[0012] Further, if the predicted analysis condition responded to by the control and analysis module is that the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, it is determined that the prediction processing module sets the predicted brightness parameters for each dynamic control region based on the predictive analysis method.

[0013] Further, if the predicted analysis condition responded to by the control and analysis module is that the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, it is determined that the balance processing module sets the predicted brightness parameters for each dynamic control region based on the balanced analysis method.

[0014] Further, the prediction processing module responds to the display analysis condition, determines the prediction execution mode according to the trajectory freedom index and the master control execution dynamic index, and determines the prediction key coefficients of each dynamic control area;

[0015] If the prediction execution condition responded by the prediction processing module is that the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master control execution dynamic index is less than or equal to the preset master control execution dynamic index, then the prediction key coefficients of each dynamic control area are determined according to the area key index and the master control execution dynamic index;

[0016] The display analysis condition is that the control analysis module determines that the prediction processing module sets the estimated brightness parameters for each dynamic control area based on the prediction analysis method within the estimated analysis period.

[0017] Further, if the prediction execution condition responded by the prediction processing module is that the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, then it is determined that the prediction key coefficients of each dynamic control area are determined according to the area trigger correlation index and the area key index, and whether to adjust the prediction key coefficients of each dynamic control area is determined according to the master control execution dynamic index;

[0018] If the key adjustment condition responded by the prediction processing module is that the master control execution dynamic index is greater than the preset master control execution dynamic index, then the prediction key coefficient is increased according to the control dynamic parameter;

[0019] The prediction key coefficients are respectively in a positive correlation with the area trigger correlation index and the area key index, and the increase value of the prediction key coefficient is in a positive correlation with the control dynamic parameter.

[0020] Further, the prediction execution module responds to the estimated setting condition, determines the estimated brightness parameters of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and determines whether to adjust the estimated brightness parameters of each dynamic control area according to the area estimated difference coefficient;

[0021] The estimated brightness parameters are respectively in a positive correlation with the prediction key coefficient and the reference area key coefficient, and the estimated setting condition is that the prediction key coefficients of each dynamic control area are all determined.

[0022] Further, if the adjustment evaluation condition responded by the prediction execution module is that the area estimated difference coefficient of a dynamic execution area is greater than the preset area estimated difference coefficient, then it is determined to adjust the estimated brightness parameter of the dynamic execution area based on the evaluation reference difference coefficient;

[0023] The adjustment value of the estimated brightness parameter is in a negative correlation with the evaluation reference difference coefficient.

[0024] Further, the equalization processing module responds to the equalization analysis condition, determines the estimated brightness parameters of each dynamic control area based on the complex parameters of the reference area and the dynamic parameters of the reference area, and determines whether to adjust the estimated brightness parameters of each dynamic control area based on the relevant estimated difference coefficient;

[0025] The adjustment evaluation condition responded by the equalization processing module is that the relevant estimated difference coefficient of a dynamic control area is greater than the preset relevant estimated difference coefficient, then it is determined that the equalization execution module adjusts the estimated brightness parameter of this dynamic control area, and this dynamic control area is recorded as the equalization execution area;

[0026] The equalization analysis condition is that the control analysis module determines that within the estimated analysis period, the equalization processing module sets the estimated brightness parameters of each dynamic control area based on the equalization analysis method.

[0027] Further, the equalization execution module responds to the equalization adjustment condition and determines the adjustment execution method according to the execution distribution index and the execution ratio index;

[0028] The adjustment determination condition responded by the equalization execution module is that the execution distribution index is less than or equal to the preset execution distribution index and the execution ratio index is less than or equal to the preset execution ratio index, and the estimated brightness parameters of each equalization processing area are adjusted according to the reference dynamic change coefficient and the reference estimated difference coefficient;

[0029] The equalization adjustment condition is that there is a dynamic control area determined by the equalization processing module to adjust the estimated brightness parameter.

[0030] Further, the adjustment determination condition responded by the equalization execution module is that the execution distribution index is greater than the preset execution distribution index or the execution ratio index is greater than the preset execution ratio index, then the equalization control set is determined according to the equalization overlap parameter, and the estimated brightness parameters of each equalization processing area within each equalization control set are adjusted according to the execution key parameter;

[0031] The adjustment value of the estimated brightness parameter has a positive correlation with the execution key parameter.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows. The technical solution of the present invention determines the regional prediction strategy within the predicted analysis period according to the display dynamic index and the display complexity index, so as to make a targeted selection for the determination process of the predicted brightness parameter of the dynamic control area, ensuring the accuracy of the determination result of the predicted brightness parameter of the dynamic control area. By determining the reference value of the backlight brightness within the predicted analysis period in advance through the predicted brightness parameter, an initial setting is made for the subsequent actual regulation process. While reducing the energy consumption of the TFT-LCD liquid crystal display, the present invention ensures the overall coordination and smoothness of the presented picture.

[0033] Furthermore, in the present invention, the display dynamic index and the display complexity index are used to characterize the degree of change and complexity of the images displayed by the display control target in the near future, and this is used to assist in the determination of the regional prediction strategy. In the case of a relatively large display dynamic index or a relatively large display complexity index, there will be relatively frequent regulation in the control process of the backlight brightness, which will affect the coordination and smoothness of the presented situation of the images. Therefore, the content that may be displayed within the predicted analysis period is predicted, and the predicted brightness parameter is determined accordingly.

[0034] Furthermore, when setting the predicted brightness parameter for each dynamic control area based on the prediction analysis method in the present invention, the prediction execution method is determined according to the trajectory freedom index and the main control execution dynamic index, further ensuring the accuracy of the determination result of the prediction key coefficient for the dynamic control area. The degree of limitation of the movement range of the prediction control target within the predicted analysis period is determined through the trajectory freedom index and the main control execution dynamic index, that is, the richness of different pictures that may need to be presented. When both the trajectory freedom index and the main control execution dynamic index are relatively small, the prediction key coefficient of each dynamic control area is determined according to the regional key index and the main control execution dynamic index. The load situation of each dynamic control area for presenting complex images is characterized by the regional key index and the main control execution dynamic index. The present invention ensures the accuracy of the determination result of the prediction key coefficient for the dynamic control area, thereby improving the overall coordination and smoothness of the presented picture in the actual regulation process.

[0035] Furthermore, in the present invention, when the trajectory freedom index is large or the master control execution dynamic index is large, the predicted key coefficient of each dynamic control area is determined according to the regional trigger association index and the regional key index, and whether to adjust the predicted key coefficient is determined according to the master control execution dynamic index. In this case, the moving range of the predicted control target within the estimation analysis cycle is relatively wide, which may lead to the presence of relatively rich key display resources in most dynamic control areas. The correlation between the key display resources that may be presented is characterized by the regional trigger association index, and the load conditions of each dynamic control area for complex images presented within the estimation analysis cycle are further distinguished. The present invention ensures the accuracy of the determination results of the predicted key coefficients of the dynamic control areas.

[0036] Furthermore, in the present invention, when setting the estimated brightness parameters for each dynamic control area based on the predictive analysis method, the estimated brightness parameters are determined based on the predicted key coefficients and the reference area key coefficients, and whether to adjust the estimated brightness parameters is determined according to the area estimated difference coefficient. While ensuring the reliability of the setting results of the estimated brightness parameters for each dynamic execution area, the balance of the backlight brightness of the overall display control target is ensured. The present invention improves the overall coordination and smoothness of the picture presented in the actual control process.

[0037] Furthermore, in the present invention, when the display dynamic index and the display complexity index are both small, the picture presented by the game process in the stage before the estimated analysis period is relatively stable, and the actual control operation of the backlight brightness is not frequent, which has little impact on the smoothness of the image presentation. Therefore, it is necessary to ensure the overall balance of the setting result of the estimated brightness parameter for the display control target, and determine the adjustment execution method according to the execution distribution index and the execution proportion index, so that the adjustment process of the estimated brightness parameter is more in line with the actual situation, thereby ensuring the effectiveness of the determination result of the estimated brightness parameter, and improving the overall coordination and smoothness of the picture presented in the actual control process.

[0046] Please refer to Figures 1 to 4 As shown, the present invention provides a TFT-LCD liquid crystal display based on intelligent control, including:

[0047] A display module for receiving an image signal and converting it into a visible image;

[0048] A control analysis module connected to the display module for periodically detecting the display dynamic index and the display complexity index, and determining the area prediction strategy within the predicted analysis period according to the display dynamic index and the display complexity index. The area prediction strategy is to set the estimated brightness parameters for each dynamic control area based on a prediction analysis method or a balance analysis method;

[0049] A prediction processing module, which is connected to the control analysis module, is used to determine a prediction execution mode according to the trajectory freedom index and the master control execution dynamic index. The prediction execution mode is to determine the prediction key coefficient of each dynamic control area according to the area key index and the master control execution dynamic index, or to determine the prediction key coefficient of each dynamic control area according to the area trigger correlation index and the area key index;

[0050] A prediction execution module, which is respectively connected to the display module and the prediction processing module, is used to determine the estimated brightness parameter of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and determine whether to adjust the estimated brightness parameter according to the area estimated difference coefficient;

[0051] An equalization processing module, which is respectively connected to the display module and the control analysis module, is used to determine the estimated brightness parameter of each dynamic control area based on the reference area complexity parameter and the reference area dynamic parameter, and determine whether to adjust the estimated brightness parameter based on the relevant estimated difference coefficient;

[0052] An equalization execution module, which is connected to the equalization processing module, is used to determine an adjustment execution mode according to the execution distribution index and the execution proportion index. The adjustment execution mode is to adjust the estimated brightness parameter of each equalization processing area according to the reference dynamic change coefficient and the reference estimated difference coefficient, or to determine an equalization control set according to the equalization overlap parameter.

[0053] Among them, the present invention is used for controlling the backlight brightness of a TFT-LCD liquid crystal display during the game process. During the game process, the image display tasks are often not fully known. It is necessary to perform real-time zonal control on the backlight brightness of the TFT-LCD liquid crystal display according to the image content presented at each moment, so as to reduce the power consumption of the liquid crystal display while ensuring the image presentation effect of the liquid crystal display. In the present invention, the display module is a TFT-LCD liquid crystal display. A thin film transistor is provided on each pixel of the TFT-LCD liquid crystal display. The light emitted by the backlight passes through each optical component and enters the liquid crystal layer. The thin film transistor generates a voltage to control the rotation direction of the liquid crystal molecules, thereby adjusting the light penetration amount to form different pixel brightnesses. By adjusting the backlight intensity, the power consumption of the liquid crystal display can be effectively reduced. The TFT-LCD liquid crystal display for which real-time zonal control is to be performed is denoted as the display control target, and the screen range corresponding to the display control target is divided into several rectangular areas with the same area, denoted as dynamic control areas. The user can set the number of the obtained dynamic control areas according to the actual working conditions. The higher the user's requirement for the backlight regulation quality of the display control target, the larger the number of the obtained dynamic control areas. After the estimated brightness parameters of each dynamic control area are determined, the reference backlight brightness of each dynamic control area is determined according to the estimated brightness parameters. The reference backlight brightness and the estimated brightness parameters are in a positive correlation relationship. During the process of regulating the backlight brightness of each dynamic control area within the estimated analysis period, the reference backlight brightness of each dynamic control area is regulated according to the actually displayed image, which can ensure the timeliness of the regulation result of the backlight brightness and the image presentation effect on the premise of reducing the power consumption of the display control target. How to regulate the reference backlight brightness of each dynamic control area according to the actually displayed image is already mastered by those skilled in the art and will not be elaborated here;

[0054] In the present invention, several backlight control records are applied. Any backlight control record records at least one display dynamic index, display complexity index, trajectory freedom index, main control execution dynamic index, regional estimation difference coefficient, regional interval parameter, related estimation difference coefficient, execution distribution index, execution proportion index, and equilibrium overlap parameter during the process of real-time regulating the backlight intensity of the display control target. And each backlight control record corresponds to a qualified mark, and the qualified mark records whether the backlight regulation quality of the display control target meets the user's requirements.

[0055] Specifically, if the estimated analysis condition responded by the control analysis module is that the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, it is determined that the prediction processing module sets the estimated brightness parameters of each dynamic control area based on the prediction analysis method.

[0056] Specifically, the estimated analysis condition responded by the control analysis module is that the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, then it is determined that the equalization processing module sets the estimated brightness parameters for each dynamic control area based on the equalization analysis method.

[0057] Among them, the present invention applies a display analysis period, and the duration of the display analysis period can be determined by the user himself. The higher the user's requirement for the backlight regulation quality of the display control target, the shorter the duration of the display analysis period. A value of the duration of the display analysis period is provided. The duration of the display analysis period is 1 min. At the end of each display analysis period, the display dynamic index and the display complexity index are detected. Since the image content required to be presented during the actual game process is not completely known, it is impossible to set the backlight brightness in advance according to the images to be displayed at each moment. Therefore, it is necessary to make a targeted prediction for the image situation to be presented and determine the targeted prediction process according to the actual display situation;

[0058] If the current moment is the end of a display analysis period, the display dynamic index and the display complexity index of this display analysis period are detected to determine the regional estimation strategy within the estimated analysis period, and the image frames corresponding to each moment within this display analysis period are obtained and recorded as display analysis images. The display dynamic index is the average value of the display dynamic parameters of each adjacent display image combination within the display analysis period. If there are no other display analysis images between the moments corresponding to two display analysis images, the above two display analysis images are recorded as an adjacent display image combination. For a single adjacent display image combination, the display dynamic parameter = the average value of the absolute values of the differences between the pixel brightness values at the same pixel positions in the two display analysis images within this adjacent display image combination / the maximum value of the pixel brightness values in the two display analysis images within this adjacent display image combination. The display complexity index is the average value of the image complexity parameters of each display analysis image within this display analysis period. For a single display analysis image, the image complexity parameter = (the maximum brightness value of each pixel point included in this display analysis image - the minimum brightness value of each pixel point included in this display analysis image) / the maximum brightness value of each pixel point included in each display analysis image within this display analysis period. The estimated analysis period is the display analysis period starting from the current moment;

[0059] The values of the preset display dynamic index and the preset display complexity index can be determined by the user according to the actual working scenario. For example, the user can set according to the backlight control record. The higher the user's requirement for the backlight regulation quality of the display control target, the smaller the value of the preset display dynamic index and the smaller the value of the preset display complexity index. A method for obtaining the value of the preset display dynamic index is provided. The backlight control record obtained by setting the estimated brightness parameters for each dynamic control area based on the equilibrium analysis method is recorded as the display reference record. The average value of the display dynamic index in the display reference records that meet the user's requirement for the backlight regulation quality of the display control target is recorded as the preset display dynamic index. A method for obtaining the value of the preset display complexity index is provided. The average value of the display complexity index in the display reference records that meet the user's requirement for the backlight regulation quality of the display control target is recorded as the preset display complexity index.

[0060] Specifically, the prediction processing module responds to the display analysis condition and determines the prediction execution method according to the trajectory freedom index and the master control execution dynamic index to determine the prediction key coefficient of each dynamic control area.

[0061] If the prediction execution condition responded by the prediction processing module is that the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master control execution dynamic index is less than or equal to the preset master control execution dynamic index, then the prediction key coefficient of each dynamic control area is determined according to the area key index and the master control execution dynamic index.

[0062] The display analysis condition is that the control analysis module determines that the prediction processing module sets the estimated brightness parameters for each dynamic control area based on the prediction analysis method within the estimated analysis period.

[0063] Among them, if the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, it indicates that the degree of change of the corresponding displayed image or the complexity of the displayed image in the previous stage before the estimated analysis period is relatively large. During the process of controlling the backlight brightness of different areas in real time according to the displayed content, the degree of change of the image and the complexity of the image are likely to cause frequent regulation in the process of controlling the backlight brightness, thereby affecting the coordination and smoothness of the image presentation and affecting the user experience. In such cases, it is necessary to predict the image situation to be presented within the estimated analysis period, and then determine the prediction key coefficient of each dynamic control area to characterize the demand for backlight brightness of each dynamic control area within the estimated analysis period, and determine the prediction execution method according to the trajectory freedom index and the master control execution dynamic index.

[0064] The specific target whose position change is completed through the operation of the user of the display control target during the game process is denoted as the predictive control target. When detecting the trajectory freedom index and the main control execution dynamic index, the position change situation should be limited to a plane parallel to the actual game map during the process of determining the trajectory freedom index and the main control execution dynamic index. The trajectory freedom index = the sum of the coverage angle parameters of each control execution trajectory of the predictive control target at the current moment / 360°. The control execution trajectory is the trajectory where the predictive control target can achieve position change at the current position. For a single execution control trajectory, the coverage angle parameter = the maximum angle value of the angle formed by the current position of the predictive control target and any position in this execution control trajectory - the minimum angle value of the angle formed by the current position of the predictive control target and any position in this execution control trajectory. When determining the angle, the current position of the predictive control target is used as the origin, and the horizontal right direction is used as the reference line;

[0065] The present invention applies a control monitoring period, and the duration of the control monitoring period can be determined by the user himself. The higher the user's requirement for the backlight regulation quality of the display control target, the shorter the duration of the control monitoring period. A value for the duration of the control monitoring period is provided. The duration of the control monitoring period is 2s. At the end of each control monitoring period, the acceleration of the predictive control target is detected. The main control execution dynamic index is the sum of the control movement parameter and the control dynamic parameter. The control movement parameter = the average value of the acceleration values of the predictive control target obtained each time in the previous display analysis period of the estimation analysis period / the maximum value of the acceleration values of the predictive control target obtained each time in the previous display analysis period of the estimation analysis period. The control dynamic parameter s is the number of times the acceleration of the predictive control target is detected in the previous display analysis period of the estimation analysis period, dt is the acceleration value of the predictive control target obtained at the t-th time in the previous display analysis period of the estimation analysis period, and L0 is the average value of the acceleration values of the predictive control target obtained each time in the previous display analysis period of the estimation analysis period;

[0066] The values of the preset trajectory freedom index and the preset master execution dynamic index can be determined by the user according to the actual working scenario. For example, the user can set according to the backlight control record. A method for obtaining the value of the preset trajectory freedom index is provided. The backlight control record for determining the prediction key coefficient of each dynamic control area based on the area key index and the master execution dynamic index is recorded as the prediction reference record. The maximum value of the trajectory freedom index in the prediction reference record that meets the user's backlight regulation quality requirements for the display control target is recorded as the preset trajectory freedom index. A method for obtaining the value of the preset master execution dynamic index is provided. The maximum value of the master execution dynamic index in the prediction reference record that meets the user's backlight regulation quality requirements for the display control target is recorded as the preset master execution dynamic index;

[0067] When the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master execution dynamic index is less than or equal to the preset master execution dynamic index, it indicates that the movement range of the prediction control target within the estimation analysis period is relatively limited. Therefore, by estimating the content that may be triggered within the estimation analysis period and using this to judge the prediction key coefficient of each dynamic control area, the game image information triggered at any position within the prediction processing range of the prediction control target is obtained. For a single position, the triggered game image information is the dynamic control areas involved in each key display resource that can be triggered when at this position. The key display resource is the trigger resource that the display control target needs to complete the display when the prediction control target is at this position. The trigger resource is a non-player controlled character that needs to be displayed after meeting the predetermined conditions. How to obtain the key display resources that can be triggered at each position is easily understood by those skilled in the art and will not be elaborated here. The prediction processing range is a circular area with the position at the current moment as the center and the prediction processing length as the radius. The prediction processing length has a positive correlation with the master execution dynamic index;

[0068] For a single dynamic control area, the prediction key coefficient has a positive correlation with the area richness reference value. The area richness reference value is the sum of the area key index and the master execution dynamic index. The area key index = the number of key display resources involved in this dynamic control area within the estimation analysis period / the number of key display resources involved in the display control target within the estimation analysis period. By using the area key index and the master execution dynamic index, the burden situation of each dynamic control area for presenting complex resources and the change situation of the picture within the estimation analysis period are judged to ensure that the setting of the estimated brightness parameter for the dynamic control area can meet the requirements of the actual display quality.

[0069] Specifically, when the prediction execution condition to which the prediction processing module responds is that the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, it is determined that the prediction key coefficients of each dynamic control area are determined according to the area trigger correlation index and the area key index, and it is determined whether to adjust the prediction key coefficients of each dynamic control area according to the master control execution dynamic index;

[0070] When the key adjustment condition to which the prediction processing module responds is that the master control execution dynamic index is greater than the preset master control execution dynamic index, the prediction key coefficient is increased according to the control dynamic parameter;

[0071] The prediction key coefficients are respectively in a positive correlation with the area trigger correlation index and the area key index, and the increase value of the prediction key coefficient is in a positive correlation with the control dynamic parameter.

[0072] Among them, when the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, it indicates that the movement range of the prediction control target within the estimated analysis period is relatively wide. Therefore, when estimating the content that may be triggered within the estimated analysis period, the triggering resources involved are too rich, and it is necessary to further analyze the correlation between different triggering resources to ensure the effectiveness of the determined prediction key coefficient. For a single dynamic control area, the prediction key coefficient is in a positive correlation with the area effective trigger reference value, and the area effective trigger reference value is the sum of the area trigger correlation index and the area key index. The area trigger correlation index = the maximum value of the trigger correlation parameters of each control execution trajectory within the estimated analysis period / the number of key display resources involved in this dynamic control area within the estimated analysis period. For a single control execution trajectory, the trigger correlation parameter is the number of key display resources corresponding to the position within this control execution trajectory among the key display resources involved in this dynamic control area when they are determined as key display resources.

[0073] Specifically, the prediction execution module responds to the estimation setting condition, determines the estimated brightness parameters of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and determines whether to adjust the estimated brightness parameters of each dynamic control area according to the area estimation difference coefficient;

[0074] The estimated brightness parameters are respectively in a positive correlation with the prediction key coefficient and the reference area key coefficient, and the estimation setting condition is that the prediction key coefficients of each dynamic control area are all determined.

[0075] Among them, for a single dynamic control area, the estimated brightness parameter and the display reference coefficient have a positive correlation. The display reference coefficient = the predicted key coefficient of this dynamic control area × the reference area key coefficient. The reference area key coefficient is the average value of the area key coefficients of each display analysis period within the reference evaluation stage of the estimated analysis period. The end time of the reference evaluation stage is the start time of the estimated analysis period. The duration of the reference evaluation stage can be set by the user according to actual needs. The higher the user's requirement for the backlight adjustment quality of the display control target, the longer the duration of the reference evaluation stage. A value for the duration of the reference evaluation stage is provided. The duration of the reference evaluation stage is ten times the duration of the display analysis period. For a single display analysis period, the area key coefficient = the maximum value reached by the backlight brightness value of this dynamic control area within this display analysis period / the maximum value that the backlight brightness value of this dynamic control area can reach.

[0076] Specifically, the adjustment evaluation condition responded to by the prediction execution module is that the area estimation difference coefficient of the dynamic execution area exists and is greater than the preset area estimation difference coefficient, then it is determined that the estimated brightness parameter for this dynamic execution area is adjusted based on the evaluation reference difference coefficient;

[0077] The adjustment value of the estimated brightness parameter has a negative correlation with the evaluation reference difference coefficient.

[0078] Among them, for a single dynamic execution area whose estimated brightness parameter has been determined, this dynamic execution area is denoted as the target evaluation area. The area estimation difference coefficient = the average value of the estimated brightness difference values of each dynamic execution area within the evaluation execution set of the target evaluation area / the maximum value of the estimated brightness difference values of each dynamic execution area within the evaluation execution set of the target evaluation area. The evaluation execution set is a set of several dynamic execution areas. The area interval parameters of each dynamic execution area within the evaluation execution set are all less than the preset area interval parameter. For any dynamic execution area within the evaluation execution set, the estimated brightness difference value is the absolute value of the difference between the estimated brightness parameter of this dynamic execution area and the estimated brightness parameter of the target evaluation area. The area interval parameter is the interval distance between the center of gravity point of the corresponding range of this dynamic execution area and the center point of the corresponding range of the target evaluation area corresponding to the evaluation execution set;

[0079] The values of the preset area estimation difference coefficient and the preset area interval parameter can be determined by the user according to the actual working scenario. For example, the user can set according to the backlight control record. The higher the user's requirement for the backlight control quality of the display control target, the smaller the value of the preset area estimation difference coefficient and the smaller the value of the preset area interval parameter. A method for obtaining the value of the preset area estimation difference coefficient is provided. The backlight control record for adjusting the estimated brightness parameter of the dynamic execution area based on the evaluation reference difference coefficient is recorded as the reference display adjustment record. The average value of the area estimation difference coefficients of each dynamic execution area in the reference display adjustment record that meets the user's requirement for the backlight control quality of the display control target is recorded as the preset area estimation difference coefficient. A method for obtaining the value of the preset area interval parameter is provided. The maximum value of the area interval parameters of each dynamic execution area in the evaluation execution set in the backlight control record that meets the user's requirement for the backlight control quality of the display control target is recorded as the preset area interval parameter;

[0080] If the area estimation difference coefficient of the dynamic control area is greater than the preset area estimation difference coefficient, it indicates that there is generally a large difference between the estimated brightness parameter determined by this dynamic control area and the estimated brightness parameters of its adjacent dynamic control areas. To avoid excessive differences in the backlight brightness between different dynamic control areas and ensure the actual picture presentation effect, it is necessary to adjust the estimated brightness parameter of the dynamic control area. For a dynamic control area where the area estimation difference coefficient of a single area is greater than the preset area estimation difference coefficient, the evaluation reference difference coefficient is the average value of the estimated brightness difference values of each dynamic execution area in the evaluation execution set of this dynamic control area. Detect the dominant difference index of this dynamic control area. The dominant difference index n is the number of dynamic execution areas in the evaluation execution set of this dynamic control area, y is the estimated brightness parameter of this dynamic control area, yi is the estimated brightness parameter of the i-th dynamic execution area in the evaluation execution set of this dynamic control area. If the dominant difference index of this dynamic control area is greater than 0, then the estimated brightness parameter of this dynamic execution area is adjusted downward. If the dominant proportion trend value of this dynamic control area is less than or equal to 0, then the estimated brightness parameter of this dynamic execution area is adjusted upward.

[0081] Specifically, the equalization processing module responds to the equalization analysis condition, determines the estimated brightness parameter of each dynamic control area based on the reference area complexity parameter and the reference area dynamic parameter, and determines whether to adjust the estimated brightness parameter of each dynamic control area based on the relevant estimation difference coefficient;

[0082] The adjustment evaluation condition for which the equalization processing module responds is that the relevant prediction difference coefficient of the dynamic control area exists and is greater than the preset relevant prediction difference coefficient. Then, it is determined that the equalization execution module adjusts the predicted brightness parameter for the dynamic control area, and this dynamic control area is recorded as the equalization execution area;

[0083] The equalization analysis condition is that the control analysis module determines that within the prediction analysis period, the equalization processing module sets the predicted brightness parameters for each dynamic control area based on the equalization analysis method.

[0084] Among them, if the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, it indicates that both the degree of change of the corresponding displayed image and the load degree of the displayed image in the previous stage before the prediction analysis period are relatively low. That is, the picture presented during the game process is relatively stable. In fact, during the control process of the backlight brightness, the regulation operations are not frequent, and the impact on the smoothness of the image presentation situation is small. Therefore, only the coordination of the picture presentation is evaluated and further adjustments are made;

[0085] When setting the predicted brightness parameters for each dynamic control area based on the equalization analysis method, for a single dynamic control area, the predicted brightness parameter has a positive correlation with the area reference coefficient. The area reference coefficient is the sum of the reference area complexity parameter and the reference area dynamic parameter of this dynamic control area. The part of the image within the corresponding range of this dynamic control area in each display analysis image in the previous display analysis period before the prediction analysis period is recorded as the equalization reference image of this dynamic control area. The reference area complexity coefficient is the average value of the area complexity parameters of each equalization reference image, and the reference area dynamic parameter is the average value of the area dynamic parameters of each combination of adjacent reference images. For a single equalization reference image, the area complexity parameter = (the maximum brightness value of each pixel point included in this equalization reference image - the minimum brightness value of each pixel point included in this equalization reference image) / the maximum brightness value of each pixel point included in each display analysis image within this equalization reference image. If there is no other equalization reference image between the moments corresponding to two equalization reference images, these two equalization reference images are recorded as an adjacent reference image combination. For a single adjacent reference image combination, the area dynamic parameter = the average value of the absolute value of the difference between the pixel brightness values at the same pixel position in the two equalization reference images within this adjacent reference image combination / the maximum value of the pixel brightness values in the two equalization reference images within this adjacent reference image combination. The relevant prediction difference coefficient e is the number of dynamic execution areas in the evaluation execution set of the target evaluation area, Lf is the predicted brightness parameter of the f-th dynamic execution area in the evaluation execution set of the target evaluation area, and L0 is the average value of the predicted brightness parameters of each dynamic execution area in the evaluation execution set of the target evaluation area;

[0086] For the value of the preset relevant estimation difference coefficient, the user can determine it according to the actual working scenario. For example, the user can set it according to the backlight control record. The higher the user's requirement for the backlight regulation quality of the display control target, the smaller the value of the preset relevant estimation difference coefficient. A method for obtaining the value of the preset relevant estimation difference coefficient is provided. The backlight control record for adjusting the estimated brightness parameter of the dynamic control area under the balanced analysis condition is recorded as the balanced regulation record, and the minimum value of the relevant estimation difference coefficient in the balanced regulation record that meets the user's requirement for the backlight regulation quality of the display control target is recorded as the preset relevant estimation difference coefficient.

[0087] Specifically, the balanced execution module responds to the balanced adjustment condition and determines the adjustment execution mode according to the execution distribution index and the execution proportion index.

[0088] The adjustment determination condition to which the balanced execution module responds is that the execution distribution index is less than or equal to the preset execution distribution index and the execution proportion index is less than or equal to the preset execution proportion index, and the estimated brightness parameter of each balanced processing area is adjusted according to the reference dynamic change coefficient and the reference estimation difference coefficient.

[0089] The balanced adjustment condition is that there is a dynamic control area determined by the balanced processing module to adjust the estimated brightness parameter.

[0090] Among them, the execution distribution index is the average value of the number of balanced processing areas existing in the evaluation execution set of each balanced processing area, and the execution proportion index = the number of balanced processing areas where the display control target exists / the number of dynamic control areas where the display control target exists. For the values of the preset execution distribution index and the preset execution proportion index, the user can determine them according to the actual working scenario. For example, the user can set them according to the backlight control record. A method for obtaining the value of the preset execution distribution index is provided. The backlight control record for adjusting the estimated brightness parameter of each balanced processing area according to the reference dynamic change coefficient and the reference estimation parameter is recorded as the balanced regulation reference record, and the maximum value of the execution distribution index in the balanced regulation reference record that meets the user's requirement for the backlight regulation quality of the display control target is recorded as the preset execution distribution index. A method for obtaining the value of the preset execution proportion index is provided. The maximum value of the execution proportion index in the balanced regulation reference record that meets the user's requirement for the backlight regulation quality of the display control target is recorded as the preset execution proportion index.

[0091] If the execution distribution index is less than or equal to the preset execution distribution index and the execution proportion index is less than or equal to the preset execution proportion index, it indicates that there are fewer dynamic control areas in the display control target that need to be balanced and the distribution of the balanced processing areas is relatively dispersed. Therefore, by processing a single balanced processing area, the overall balance of the picture can be improved. For a single balanced processing area, the reference dynamic variation coefficient = (the maximum value of the regional dynamic parameters of each adjacent reference image combination - the minimum value of the regional dynamic parameters of each adjacent reference image combination) / the average value of the regional dynamic parameters of each adjacent reference image combination. The reference estimated difference coefficient is the absolute value of the regional estimated difference coefficient. The regional estimated difference coefficient m is the number of dynamic execution areas in the evaluation execution set of the equalizing processing area, p is the estimated brightness parameter of the equalizing processing area, pj is the estimated brightness parameter of the jth dynamic execution area in the evaluation execution set of the equalizing processing area, if the regional estimated difference coefficient of the equalizing processing area is greater than 0, the estimated brightness parameter of the equalizing processing area is adjusted to decrease, if the regional estimated difference coefficient of the equalizing processing area is less than or equal to 0, the estimated brightness parameter of the equalizing processing area is adjusted to increase, the adjustment value of the estimated brightness parameter is positively correlated with the independent control parameter, the independent control parameter = reference estimated difference coefficient / reference dynamic change coefficient, so that during the adjustment process, while ensuring the balance of the backlight brightness of different areas, the actual picture display requirements are taken into account.

[0092] Specifically, if the adjustment determination condition responded by the balanced execution module is that the execution distribution index is greater than the preset execution distribution index or the execution proportion index is greater than the preset execution proportion index, the balanced control set is determined according to the balanced overlap parameter, and the estimated brightness parameter of each balanced processing area in each balanced control set is adjusted according to the execution key parameter;

[0093] The adjustment value of the estimated brightness parameter is positively correlated with the execution key parameter.

[0094] If the execution distribution index is greater than the preset execution distribution index or the execution proportion index is greater than the preset execution proportion index, it indicates that there are many dynamic control areas of the display control target that need to be balanced or the balanced processing areas are relatively concentrated, and it is necessary to adjust according to the overall situation of the areas where the balanced processing areas are mainly concentrated to ensure the overall balance of the picture;

[0095] Perform an equilibrium regulation set division for the equilibrium processing regions existing for the display control target. The equilibrium overlap parameters of each equilibrium regulation set are all greater than the preset equilibrium overlap parameter. For a single equilibrium regulation set, the equilibrium overlap parameter is the average value of the number of equilibrium processing regions within the evaluation execution set of each equilibrium processing region within this equilibrium regulation set that exist within this equilibrium regulation set. For any one equilibrium processing region within this equilibrium regulation set, the adjustment value of the estimated brightness parameter is positively correlated with the execution key parameter, and the execution key parameter = the relevant estimated difference coefficient of this equilibrium processing region / the relevant estimated difference coefficient of each equilibrium processing region within this equilibrium regulation set. If the regional estimated difference coefficient of this equilibrium processing region is greater than 0, then perform a decreasing adjustment on the estimated brightness parameter of this equilibrium processing region. If the regional estimated difference coefficient of this equilibrium processing region is less than or equal to 0, then perform an increasing adjustment on the estimated brightness parameter of this equilibrium processing region;

[0096] For the value of the preset equilibrium overlap parameter, the user can determine it according to the actual working scenario. For example, the user can set it according to the backlight control record. The higher the user's requirement for the backlight regulation quality of the display control target, the larger the value of the preset equilibrium overlap parameter. Provide a method for obtaining the value of the preset equilibrium overlap parameter, and record the minimum value of the equilibrium overlap parameters of each equilibrium regulation set in the backlight control record that meets the user's requirement for the backlight regulation quality of the display control target as the preset equilibrium overlap parameter.
