[0041] In order to more clearly illustrate the present application, the present application will be further described below with reference to the preferred embodiments and the accompanying drawings. Like components are denoted by the same reference numerals in the drawings. It should be understood by those skilled in the art that the specific description below is illustrative rather than limiting, and should not limit the scope of protection of the present application.

[0042] In the related art, improving the liquid crystal response time of a reality device is generally approached from four aspects: reducing the viscosity coefficient of the liquid crystal material, reducing the thickness of the liquid crystal cell, increasing the dielectric constant of the liquid crystal material, and increasing the driving voltage. Among them, the viscosity coefficient of the liquid crystal material and the dielectric constant of the liquid crystal material are related to the characteristics of the liquid crystal material itself, and generally a liquid crystal material that meets the fast response requirement is selected during design; in addition, the thickness of the liquid crystal cell is reduced as much as possible to improve the response speed, but the thickness of the liquid crystal cell cannot be reduced indefinitely due to the characteristics of the liquid crystal material itself; increasing the driving voltage generally changes the voltage of the screen end liquid crystal molecules, increases the torque on the liquid crystal molecules, accelerates the rotation of the liquid crystal molecules, and forces the liquid crystal molecules to change the arrangement and convert into the set transmittance in a shorter time to achieve the function of accelerating the screen response speed. However, if the driving voltage is set too low, ghosting will occur when the rendered color value is less than the target value, and if the driving voltage is set too high, artifacts will occur when the rendered color value is greater than the target value.

[0043] In view of the above, as shown in Figure 1 An embodiment of the present application provides a reality device, comprising a control chip, a liquid crystal display panel, and a backlight source, wherein

[0044] The backlight source comprises backlight sub-zones arranged in an array;

[0045] The liquid crystal display panel comprises display sub-zones corresponding to the backlight sub-zones one by one;

[0046] The control chip is electrically coupled with the backlight source and the liquid crystal display panel, and is configured to:

[0047] receive a picture to be displayed and determine, according to the gray scale values of the pixels in the picture to be displayed, a target display sub-zone corresponding to each pixel and a liquid crystal response time corresponding to the target display sub-zone, the target display sub-zone being a display sub-zone comprising a pixel having the maximum gray scale value in the picture to be displayed;

[0048] determining whether the liquid crystal response time is greater than a preset response time threshold, and if so, calculating a degraded gray scale value corresponding to the target display partition and backlight compensation brightness, obtaining a degraded gray scale value set corresponding to each display partition in the picture to be displayed, and obtaining a backlight compensation set of each backlight partition corresponding to each display partition, the degraded gray scale value being less than or equal to the original gray scale value of the target display partition;

[0049] controlling the liquid crystal deflection angle of each display partition of the liquid crystal display panel according to the degraded gray scale value set, and controlling the display brightness of each backlight partition of the backlight source according to the backlight compensation set.

[0050] In the embodiment, the target display partition of the pixel with the maximum gray scale value in the picture to be displayed is first obtained by the control chip electrically coupled with the liquid crystal display panel and the backlight source, and the required liquid crystal response time is obtained. Then, the liquid crystal response time is compared with the response time threshold of the liquid crystal real device. When the liquid crystal response time is greater than the response time threshold, the degraded gray scale value corresponding to the target display partition and the backlight compensation brightness are calculated. Further, the degraded gray scale value set corresponding to each display partition and the backlight compensation set of the corresponding backlight partition are obtained. Finally, the liquid crystal deflection angle of each display partition of the liquid crystal display panel is controlled according to the degraded gray scale value set, and the display brightness of each backlight partition of the backlight source is controlled according to the backlight compensation set. The embodiment reduces the liquid crystal deflection angle of the pixel of the target display partition to reduce the liquid crystal response time, and at the same time uses the backlight brightness to compensate for the brightness reduction caused by the reduced liquid crystal deflection angle, so as to realize the display effect of the original gray scale by degrading the pixel and backlight compensation, thereby improving the display abnormal problem caused by the insufficient liquid crystal response time in the related art, effectively improving the display effect, and having a wide application prospect.

[0051] In one specific example, the reality device can be one of a virtual reality device, an augmented reality device, a mixed reality device, and an extended reality device. A virtual reality (VR) device provides a completely virtual and interactive digital world, simulates reality in three-dimensional space for users through headsets, controllers, etc., provides visual, auditory, etc. sensory to users, has strong "presence" and "immersion", and is not limited by physical environmental conditions. An augmented reality (AR) device skillfully combines virtual information with the real world, uses multimedia, three-dimensional modeling, real-time tracking, etc. to superimpose real environment and virtual objects in the same picture. A mixed reality (MR) device combines the real world and the virtual world, can build an information loop for interaction and feedback between the real world, the virtual world and the user, and enhances the realism of user experience. An extended reality (XR) device provides a combination of real and virtual environments through computer technology and wearable devices, and human-computer interaction.

[0052] As shown in Figures 1-3 As shown in Figure 1 is a structural schematic diagram of a reality device, as shown in Figure 2 is a structural schematic diagram of a liquid crystal display panel, and as shown in Figure 3 is a structural schematic diagram of a backlight.

[0053] As shown in Figure 2 The liquid crystal display panel includes an array substrate 20, an opposite substrate 40 opposite to the array substrate 20, a liquid crystal 30 disposed between the array substrate 20 and the opposite substrate 40, a first polarizer 10 disposed on the side of the array substrate 20 close to the backlight, and a second polarizer 50 disposed on the light-emitting side of the opposite substrate 40. The control chip is electrically coupled to the liquid crystal display panel, and sends a control signal to the liquid crystal display panel. For example, during the display of a frame of image, after the liquid crystal 30 completes the angle deflection, the first polarizer 10 is controlled to be opened, so that the liquid crystal display panel receives and transmits the light emitted by the backlight.

[0054] As shown in Figure 3As shown, the backlight source includes an array of independent light emitting devices, such as light emitting diodes, which can be LEDs, miniLEDs, and microLEDs. The miniLED is a sub-millimeter light emitting diode, and the chip size of the LED is between 50-200 μm. Compared with the traditional LED, the miniLED has smaller volume, shorter light mixing distance, higher brightness and contrast, lower power consumption, longer service life, and other characteristics. The microLED is a micro light emitting diode, which is a thin film, miniaturization and array of LED backlight. Compared with the traditional LED, the microLED has high brightness, high contrast, high definition, strong reliability, fast response time, more energy saving, lower power consumption, and other characteristics.

[0055] As shown Figure 3 The backlight source of the present embodiment includes 18×32 576 partitions formed by 18 horizontal partitions 101 and 32 vertical partitions 102. Each CH backlight partition can include at least one independently controllable light emitting device according to the corresponding liquid crystal display screen. To drive the light emitting devices of each backlight partition, the backlight source includes a first electrode 201 covering multiple rows of backlight partitions, and a second electrode 103 corresponding to each backlight partition. Each light emitting device of each backlight partition CH is lit according to the voltage loaded on the first electrode 201 and the second electrode 103. The control chip is electrically coupled to the backlight source and sends a control signal to the backlight source. For example, during the display of a frame of image, after the liquid crystal of the liquid crystal display panel completes the angle deflection, a first voltage is applied to the first electrode, and a second voltage is applied to the second electrode of each backlight partition covered by the first electrode to light the light emitting devices of each backlight partition of the backlight source.

[0056] In the present embodiment, according to the requirements of the real device including the liquid crystal display panel for the liquid crystal response time, the control chip analyzes the gray scale value of each pixel of the to-be-displayed picture to determine the target display partition and the corresponding liquid crystal response time. According to the liquid crystal response time of the to-be-displayed picture and the response time threshold of the real device for the liquid crystal response time, it is judged whether to degrade the display gray scale of the liquid crystal of each display partition of the liquid crystal display panel and compensate by increasing the backlight brightness of the corresponding backlight partition, so as to reduce the liquid crystal response time by reducing the pixel gray scale and the liquid crystal deflection angle, and at the same time compensate for the brightness reduction caused by the reduced liquid crystal deflection angle by increasing the backlight brightness, that is, realize the display effect of the original gray scale by degrading the pixel and backlight compensation, thereby improving the display abnormal problem caused by insufficient liquid crystal response time in the related art, effectively improving the display effect, and having wide application prospect.

[0057] To further illustrate the specific embodiments of the present application, the display of a to-be-displayed picture by a real device is taken as an example for illustration, which specifically includes the following steps:

[0058] In a first step, a picture to be displayed is received and a target display partition corresponding to each pixel in the picture to be displayed is determined according to a gray scale value of each pixel in the picture to be displayed, and a liquid crystal response time corresponding to the target display partition is determined.

[0059] In this embodiment, the control chip analyzes the gray scale value of each pixel in the picture to be displayed, and derives the maximum angle of liquid crystal deflection in the display partition in the liquid crystal display panel using the maximum gray scale value in each pixel, and obtains the time required for liquid crystal deflection, i.e., the longest liquid crystal response time required by the liquid crystal display panel.

[0060] In a second step, it is determined whether the liquid crystal response time is greater than a preset response time threshold value, and if so, a degraded gray scale value corresponding to the target display partition and a backlight compensation brightness are calculated, a degraded gray scale value set corresponding to each display partition in the picture to be displayed is obtained, and a backlight compensation set corresponding to the backlight partition of each display partition is obtained, and the degraded gray scale value is less than or equal to the original gray scale value of the target display partition.

[0061] In this embodiment, the longest liquid crystal response time required by the liquid crystal display panel when displaying the picture to be displayed is compared with the response time threshold value for normal display of the real device, and if the longest response time of the picture to be displayed is less than or equal to the response time threshold value, the liquid crystal display panel is normally displayed, and there is no abnormal display of the real device. If the longest response time of the picture to be displayed is greater than the response time threshold value, the control chip reversely calculates the acceptable liquid crystal response time of the liquid crystal display panel when normally displayed according to the response time threshold value, and obtains the degraded gray scale value corresponding to the maximum gray scale value pixel according to the acceptable liquid crystal response time, i.e., calculates the maximum gray scale value that can be displayed when normally displayed as the final displayed gray scale value according to the response time threshold value, i.e., reduces the liquid crystal deflection angle by reducing the gray scale value to reduce the liquid crystal response time. At the same time, in the case of using the degraded gray scale value as the gray scale value for liquid crystal display, the backlight emitting device of the independently controlled backlight partition is compensated in brightness, so as to compensate for the difference caused by the use of the degraded gray scale value for display of the liquid crystal display panel by increasing the brightness of the backlight emitting device. Similarly, based on the degraded gray scale value corresponding to the maximum gray scale value and the backlight compensation brightness, the control chip obtains a degraded gray scale value set used by each display partition of the liquid crystal display panel and a backlight compensation set used by the corresponding backlight partition, so as to obtain the display signal required by the liquid crystal display panel and the light emitting signal required by the backlight source in the real device.

[0062] Specifically, the following steps are included:

[0063] Firstly, if the liquid crystal response time is greater than a preset response time threshold, a deflectable angle of the liquid crystal of the target display partition is obtained according to the response time threshold, and a degraded gray scale value corresponding to the original gray scale value is obtained according to the deflectable angle.

[0064] In the embodiment, when the liquid crystal response time required by the liquid crystal deflecting angle corresponding to the pixel of the maximum gray scale value of the picture to be displayed is greater than the response time threshold, the control chip calculates the deflectable angle of the liquid crystal that meets the normal display of the liquid crystal display panel according to the response time threshold, for example, the maximum deflecting angle of the liquid crystal corresponding to the response time threshold, and the liquid crystal can be normally displayed when the deflecting angle of the liquid crystal is less than or equal to the maximum deflecting angle, that is, the deflectable angle is less than or equal to the maximum deflecting angle. The control chip can select a matching gray scale value as a degraded gray scale value in the deflectable angle range according to the compensable luminance of the backlight partition, and the degraded gray scale value is less than or equal to the maximum deflecting angle of the liquid crystal in the normal display of the liquid crystal display panel.

[0065] Secondly, a gray scale difference value is obtained according to the original gray scale value and the degraded gray scale value, and the backlight compensation luminance of the backlight partition corresponding to the target display partition is obtained according to the gray scale difference value, so that the light-emitting luminance formed by superimposing the backlight compensation luminance and the degraded gray scale value is equivalent to the light-emitting luminance formed by the original gray scale value.

[0066] In the embodiment, on the basis of obtaining the degraded gray scale value corresponding to the maximum gray scale value, the corresponding backlight compensation luminance is further calculated according to the gray scale difference value of the maximum gray scale value and the degraded gray scale value. Specifically, the difference in luminance is obtained according to the difference between the degraded gray scale value and the original gray scale value, and the compensation amount required by the backlight device is calculated according to the difference to obtain the backlight compensation luminance, so as to realize that the light emitted by the degraded gray scale value displayed by the liquid crystal display panel and the backlight compensation luminance provided by the backlight source are equivalent to the light emitted by the original gray scale value and the normal luminance provided by the backlight source. It should be noted that those skilled in the art should understand that the "equivalent" in the embodiment is approximately the same within a certain range, for example, within the range of 95% to 105%, and is considered equivalent.

[0067] Thirdly, a degradation parameter is obtained according to the original gray scale value and the degraded gray scale value, and a degraded gray scale value set corresponding to each display partition in the picture to be displayed is obtained according to the degradation parameter.

[0068] In the embodiment, the degradation parameter is obtained by using the difference between the original gray scale value and the degraded gray scale value on the basis that the maximum gray scale value forms equivalent outgoing light by corresponding degraded gray scale value and backlight compensation luminance, for example, the degradation parameter is the proportional relationship between the original gray scale value and the degraded gray scale value, specifically, when the proportion of the original gray scale value and the degraded gray scale value is k, k is taken as the degradation parameter, the degraded gray scale value corresponding to other pixels in the target display partition and the degraded gray scale value corresponding to each pixel of other display partitions are calculated, thereby obtaining the degraded gray scale value corresponding to each pixel of each display partition of the liquid crystal display panel, that is, the degraded gray scale value set.

[0069] It is worth noting that the embodiment is only used to illustrate the specific embodiments of the present application, and the degradation parameter is not specifically limited in the present application, for example, the degradation parameter is a nonlinear composite parameter, and the design criterion for obtaining accurate degraded gray scale values according to the original gray scale values of different pixels is achieved, for example, it is a segmented parameter, or it is a reference table including degraded gray scale values corresponding to different gray scale values, obtaining corresponding degraded gray scale values from the reference table according to different gray scale values, etc., all of which are within the protection scope of the present application. Those skilled in the art should select appropriate degradation parameters according to actual application requirements, which will not be repeated here.

[0070] Finally, the compensation parameter is obtained according to the original gray scale value, the degraded gray scale value and the backlight compensation luminance, and the backlight compensation set of the backlight partition corresponding to each display partition is obtained according to the compensation parameter.

[0071] In the embodiment, the degradation parameter is obtained by using the difference between the original gray scale value and the degraded gray scale value on the basis that the maximum gray scale value forms equivalent outgoing light by corresponding degraded gray scale value and backlight compensation luminance, for example, the degradation parameter is the proportional relationship between the original gray scale value and the degraded gray scale value, specifically, when the proportion of the original gray scale value and the degraded gray scale value is k, k is taken as the degradation parameter, the degraded gray scale value corresponding to other pixels in the target display partition and the degraded gray scale value corresponding to each pixel of other display partitions are calculated, thereby obtaining the degraded gray scale value corresponding to each pixel of each display partition of the liquid crystal display panel, that is, the degraded gray scale value set.

[0072] In view of the limited range of the deflectable angle of the liquid crystal display panel, in an optional embodiment, when the liquid crystal response time is greater than a preset response time threshold, the deflectable angle of the liquid crystal of the target display partition is obtained according to the response time threshold, and the degraded gray scale value corresponding to the original gray scale value is further obtained according to the deflectable angle, which comprises: obtaining the gray scale values of each adjacent display partition of the target display partition respectively, determining the deflectable angle of the liquid crystal of each adjacent display partition, and determining the degraded gray scale value of each pixel of the target display partition and each adjacent display partition; the gray scale difference value is obtained according to the original gray scale value and the degraded gray scale value, and the backlight compensation brightness of the backlight partition corresponding to the target display partition is obtained according to the gray scale difference value, so that the light-emitting brightness formed by superimposing the backlight compensation brightness and the degraded gray scale value is equivalent to the light-emitting brightness formed by the original gray scale value. Further comprises: obtaining the backlight compensation brightness of the backlight partition corresponding to the target display partition and each adjacent display partition according to the degraded gray scale value of each pixel of the target display partition and each adjacent display partition, so that the light-emitting brightness formed by superimposing the target display partition and each adjacent display partition and the corresponding backlight partition is equivalent to the light-emitting brightness of each pixel of the picture to be displayed.

[0073] In this embodiment, considering that there are pixels with large gray scale value difference in the target display partition, the range of the deflectable angle of the liquid crystal is limited, and there may be a case that the degraded gray scale value corresponding to the response time threshold cannot be met, the display of the picture to be displayed is realized by adjusting the liquid crystal deflection of the target display partition and the adjacent display partition and the corresponding backlight compensation brightness. Specifically, the original gray scale value and the backlight value of each pixel are comprehensively adjusted, so that the emitted light is related to the light emission of each pixel of the target display partition and the adjacent display partition.

[0074] Thirdly, the deflectable angle of the liquid crystal of each display partition of the liquid crystal display panel is controlled according to the degraded gray scale value set, and the display brightness of each backlight partition of the backlight source is controlled according to the backlight compensation set.

[0075] In this embodiment, based on the degraded gray scale value set and the backlight compensation set obtained by the control chip, through the structure electrically coupled with the liquid crystal display panel and the backlight source, the control chip sends corresponding control signals to the liquid crystal display panel according to the degraded gray scale value set to control each pixel of each display partition of the liquid crystal display panel to display according to the corresponding degraded gray scale value, and at the same time, the control chip sends corresponding control signals to the backlight source according to the backlight compensation set to control each backlight partition of the backlight source to light up according to the corresponding backlight compensation brightness.

[0076] At this point, in the case of meeting the normal display of the real device, the display of the real device to the picture to be displayed is realized, such as Figure 4As shown, the control chip determines a target display partition based on the picture to be displayed, and obtains a downgraded gray scale value corresponding to a maximum gray scale value of the target display partition and a corresponding backlight compensation brightness. Further, the control chip obtains a set of downgraded gray scale values of each display partition and a corresponding set of backlight compensation, and controls the liquid crystal deflection angle of each display partition of the liquid crystal display panel according to the set of downgraded gray scale values, and controls the display brightness of each backlight partition of the backlight source according to the set of backlight compensation. In this embodiment, the liquid crystal response time is reduced by reducing the liquid crystal deflection angle of the pixels in the target display partition, and the reduced liquid crystal deflection angle is compensated by using the backlight brightness, so that the display effect of the original gray scale is realized by downgrading the pixels and backlight compensation. The display abnormality problem caused by insufficient liquid crystal response time in the related art is improved, the display effect is effectively improved, and the application prospect is wide.

[0077] In view of the hardware configuration and computing capability of the control chip, in an optional embodiment, the receiving a picture to be displayed and determining a corresponding target display partition according to the gray scale value of each pixel in the picture to be displayed, and the maximum liquid crystal response time of each display partition further comprises: determining the maximum gray scale value of each display partition and the maximum liquid crystal response time of each display partition according to the gray scale value of each pixel in the picture to be displayed; the judging whether the liquid crystal response time is greater than a preset response time threshold, and if yes, calculating the downgraded gray scale value and the backlight compensation brightness corresponding to the target display partition, obtaining a set of downgraded gray scale values corresponding to each display partition in the picture to be displayed, and obtaining a set of backlight compensation corresponding to the backlight partition of each display partition, the downgraded gray scale value being less than or equal to the original gray scale value of the target display partition further comprises: judging whether the maximum liquid crystal response time of each display partition is greater than a preset response time threshold, and if yes, calculating the downgraded gray scale value and the backlight compensation brightness corresponding to each display partition, obtaining a set of downgraded gray scale values corresponding to each display partition, and obtaining a set of backlight compensation corresponding to the backlight partition of each display partition; the controlling the liquid crystal deflection angle of each display partition of the liquid crystal display panel according to the set of downgraded gray scale values, and controlling the display brightness of each backlight partition of the backlight source according to the set of backlight compensation further comprises: controlling the liquid crystal deflection angle of each corresponding display partition in the liquid crystal display panel according to each set of downgraded gray scale values, and controlling the display brightness of each corresponding backlight partition in the backlight source according to each set of backlight compensation.

[0078] In the embodiment, by acquiring the maximum gray scale value of each display partition, it is judged whether the gray scale value of each display partition needs to be degraded and whether the backlight compensation is needed. If the liquid crystal response time corresponding to the maximum gray scale value of the display partition is less than the response time threshold, i.e., the display partition can meet the display requirement of the real device, the gray scale value of each pixel of the display partition does not need to be degraded, and the backlight partition corresponding to the display partition also does not need to be compensated. That is, the control chip only operates on the display partition which needs the gray scale value degradation and the backlight compensation, thereby effectively reducing the operation amount of the control chip to reduce the hardware setting requirement of the real device and reduce the cost of the real device.

[0079] Corresponding to the real device provided by the above embodiment, one embodiment of the present application also provides a display control method using the above real device, as shown in the following Figure 5 The display control method applied to the control chip includes:

[0080] receiving a picture to be displayed and determining the target display partition corresponding to each pixel in the picture to be displayed according to the gray scale value of each pixel in the picture to be displayed, and the liquid crystal response time corresponding to the target display partition, the target display partition being a display partition including the pixel with the maximum gray scale value in the picture to be displayed;

[0081] judging whether the liquid crystal response time is greater than the preset response time threshold. If yes, the degraded gray scale value corresponding to the target display partition and the backlight compensation brightness are calculated, the degraded gray scale value set corresponding to each display partition in the picture to be displayed is acquired, and the backlight compensation set of each backlight partition corresponding to each display partition is acquired, the degraded gray scale value being less than or equal to the original gray scale value of the target display partition;

[0082] controlling the liquid crystal deflection angle of each display partition of the liquid crystal display panel according to the degraded gray scale value set, and controlling the display brightness of each backlight partition of the backlight source according to the backlight compensation set.

[0083] The control chip of the embodiment first acquires a target display partition of a pixel with a maximum gray scale value in a picture to be displayed, and acquires a required liquid crystal response time; secondly, the liquid crystal response time is compared with a response time threshold of a liquid crystal actual device, when the liquid crystal response time is greater than the response time threshold, a degraded gray scale value corresponding to the target display partition and a backlight compensation brightness are calculated, and a degraded gray scale value set corresponding to each display partition and a backlight compensation set of a corresponding backlight partition are further acquired; finally, a liquid crystal deflection angle of each display partition of the liquid crystal display panel is controlled according to the degraded gray scale value set, and a display brightness of each backlight partition of the backlight source is controlled according to the backlight compensation set. The embodiment reduces the liquid crystal deflection angle of the pixel of the target display partition to reduce the liquid crystal response time, and at the same time, the backlight brightness is used to compensate for the brightness reduction caused by the reduced liquid crystal deflection angle, so as to realize the display effect of the original gray scale through the degraded pixel and the backlight compensation, which can improve the display abnormal problem caused by the insufficient liquid crystal response time in the related art, effectively improve the display effect, and has a wide application prospect. Since the display control method provided by the embodiment corresponds to the actual device provided by the above several embodiments, the preceding embodiments are also applicable to the display control method provided by the embodiment, and will not be described in detail in the embodiment.

[0084] In an optional embodiment, the judgment of whether the liquid crystal response time is greater than a preset response time threshold, and the calculation of the degraded gray scale value corresponding to the target display partition and the backlight compensation brightness if yes, the acquisition of the degraded gray scale value set corresponding to each display partition in the picture to be displayed, and the acquisition of the backlight compensation set of the backlight partition corresponding to each display partition further include: if the liquid crystal response time is greater than the preset response time threshold, the deflection angle of the liquid crystal of the target display partition is acquired according to the response time threshold, and the degraded gray scale value corresponding to the original gray scale value is acquired according to the deflection angle; the gray scale difference value is acquired according to the original gray scale value and the degraded gray scale value, the backlight compensation brightness of the backlight partition corresponding to the target display partition is acquired according to the gray scale difference value, so that the outlight brightness formed by the superposition of the backlight compensation brightness and the degraded gray scale value is equivalent to the outlight brightness formed by the original gray scale value; the degraded parameter is acquired according to the original gray scale value and the degraded gray scale value, and the degraded gray scale value set corresponding to each display partition in the picture to be displayed is acquired according to the degraded parameter; the compensation parameter is acquired according to the original gray scale value, the degraded gray scale value and the backlight compensation brightness, and the backlight compensation set of the backlight partition corresponding to each display partition is acquired according to the compensation parameter.

[0085] The control chip of the embodiment reversely deduces the acceptable liquid crystal response time and the corresponding degraded gray scale value of the liquid crystal display panel during normal display through the response time threshold of the normal display of the real device, and then obtains the backlight compensation luminance of the corresponding backlight partition according to the original gray scale value and the degraded gray scale value. Furthermore, the degraded gray scale value set used by each display partition of the liquid crystal display panel and the backlight compensation set used by the corresponding backlight partition are obtained based on the degraded gray scale value corresponding to the maximum gray scale value and the backlight compensation luminance, and each display partition of the liquid crystal display panel is controlled to display, and each backlight partition of the backlight source is controlled to emit light. For specific implementation process, please refer to the foregoing embodiments, which will not be described here.

[0086] In an optional embodiment, when the liquid crystal response time is greater than the preset response time threshold, the rotatable angle of the liquid crystal of the target display partition is obtained according to the response time threshold, and the degraded gray scale value corresponding to the original gray scale value is further obtained according to the rotatable angle. The degraded gray scale value of each pixel of the target display partition and each adjacent display partition is obtained by respectively obtaining the gray scale value of each adjacent display partition of the target display partition, determining the rotatable angle of the liquid crystal of each adjacent display partition, and determining the degraded gray scale value of each pixel of the target display partition and each adjacent display partition. The backlight compensation luminance of the corresponding backlight partition of the target display partition is obtained according to the gray scale difference, so that the light-emitting luminance formed by superimposing the backlight compensation luminance and the degraded gray scale value is equivalent to the light-emitting luminance formed by the original gray scale value. The backlight compensation luminance of the corresponding backlight partition of the target display partition and each adjacent display partition is obtained according to the degraded gray scale value of each pixel of the target display partition and each adjacent display partition, so that the light-emitting luminance formed by superimposing the target display partition and each adjacent display partition and the corresponding backlight partition is equivalent to the light-emitting luminance of each pixel of the picture to be displayed.

[0087] The embodiment considers that when there are pixels with large gray scale value difference in the target display partition, the rotatable angle of the liquid crystal has a limited range, and there is a case that the degraded gray scale value corresponding to the response time threshold cannot be met. By adjusting the liquid crystal deflection of the target display partition and the adjacent display partition and the corresponding backlight compensation luminance, the display of the picture to be displayed is realized by comprehensive adjustment of multiple display partitions. For specific implementation process, please refer to the foregoing embodiments, which will not be described here.

[0088] In an optional embodiment, the receiving of the picture to be displayed and determining the target display partition corresponding to each pixel in the picture to be displayed according to the gray scale value of each pixel in the picture to be displayed, and the liquid crystal response time corresponding to the target display partition further comprises: determining the maximum gray scale value of each display partition and the maximum liquid crystal response time of each display partition according to the gray scale value of each pixel in the picture to be displayed; the judging of whether the liquid crystal response time is greater than the preset response time threshold, and if yes, calculating the degraded gray scale value corresponding to the target display partition and the backlight compensation brightness, obtaining the degraded gray scale value set corresponding to each display partition in the picture to be displayed, and obtaining the backlight compensation set of the backlight partition corresponding to each display partition, the degraded gray scale value being less than or equal to the original gray scale value of the target display partition further comprises: judging whether the maximum liquid crystal response time of each display partition is greater than the preset response time threshold, and if yes, calculating the degraded gray scale value corresponding to each display partition and the backlight compensation brightness, obtaining the degraded gray scale value set corresponding to each display partition, and obtaining the backlight compensation set of the backlight partition corresponding to each display partition; the controlling of the liquid crystal deflection angle of each display partition of the liquid crystal display panel according to the degraded gray scale value set and the display brightness of each backlight partition of the backlight source according to the backlight compensation set further comprises: controlling the liquid crystal deflection angle of each display partition in the liquid crystal display panel according to each degraded gray scale value set, and controlling the display brightness of each backlight partition in the backlight source according to each backlight compensation set.

[0089] By obtaining the maximum gray scale value of each display partition, the present embodiment judges whether the gray scale value of each display partition needs to be degraded and whether the backlight needs to be compensated, and if the maximum gray scale value of the display partition corresponds to a liquid crystal response time less than the response time threshold, i.e., the display partition can meet the display requirements of the real device, the gray scale value of each pixel of the display partition does not need to be degraded, and the backlight partition corresponding to the display partition also does not need to be compensated. That is, the control chip only needs to perform operations on the display partition that needs to be degraded in gray scale value and compensated in backlight, thereby effectively reducing the operation amount of the control chip to reduce the hardware setting requirements of the real device and the cost of the real device.
