[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be further elaborated in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be construed as limiting the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0032] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0033] The terms "first / second / third" involved are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing this application and are not intended to limit this application.

[0035] Currently, adjusting the brightness of a laptop screen is achieved through the operating system and display driver. Moreover, many screens support Wide Color Gamut (WCG) and multi-color gamut switching. Before and after the color gamut switching of the screen, the transmittance of the liquid crystal panel will vary, resulting in inconsistent brightness performance. However, the system does not control this part of the brightness difference caused by color gamut switching, and the system and driver levels cannot control and respond immediately, thus causing the brightness to change rapidly and flicker due to the change of color gamut parameters, affecting the user experience. At the same time, parameters such as the gray scale and Gamma curve of the screen display will also affect the backlight brightness. If these parameters change suddenly, it will also cause the screen brightness to flicker.

[0036] To solve the above technical problems, an embodiment of the present application provides a parameter adjustment method, which can be applied to an electronic device. The electronic device can be an electronic device including a connection mechanism; exemplarily, the electronic device includes but is not limited to a smart phone, a tablet computer, a wearable device, a personal computer (PC), a netbook, etc., and the implementation form of the present application is not fixedly limited.

[0037] Figure 1 Schematic diagram of the implementation process of a parameter adjustment method provided by an embodiment of the present application Figure 1 , as Figure 1 shown, the parameter adjustment method can be implemented through steps S101 to S103:

[0038] Step S101, based on a display adjustment event for the display parameters of the screen, determine the parameter adjustment information of the display parameters.

[0039] Here, the display parameters of the screen can be display parameters that can affect the transmittance of the screen. Exemplarily, the display parameters include at least one of the following: color gamut value, gamma value, gray scale value, and color.

[0040] In an embodiment of the present application, the display adjustment event can also be automatically triggered by the electronic device.

[0041] In some embodiments, the display adjustment event can be triggered by the user adjusting the display parameters based on the adjustment control or adjustment button of the display.

[0042] In some embodiments, the electronic device can automatically adjust the display parameters of the screen according to the current ambient light information, thereby triggering a display adjustment event.

[0043] Exemplarily, when the current ambient light information indicates that the light is dim, the gamma value can be reduced; when the current ambient light information indicates that the light is bright, the gamma value can be reduced.

[0044] In some embodiments, the electronic device can automatically adjust the display parameters of the screen according to the current battery power, thereby triggering a display adjustment event.

[0045] It can be understood that in order to maintain the current display parameters of the screen, the electronic device needs to turn on the corresponding function, which will result in a relatively large power consumption of the electronic device. When the current battery power is low, in order to enable the electronic device to have a longer battery life, the electronic device can turn off the corresponding function at this time, or the control system is in the power-saving mode to turn off the corresponding function, so that the display parameters of the electronic device change, thereby triggering a display adjustment event for the display parameters of the screen. Exemplarily, when the display parameter is the color threshold, the above function can be the color gamut calibration function.

[0046] In some embodiments, when the electronic device recognizes that the screen displays a predetermined content, it can automatically adjust the display parameters of the screen, thereby triggering a display adjustment event.

[0047] Exemplarily, when the screen displays content of the web page type and the display parameter is the color threshold, the current color gamut mode can be switched to the standard color gamut mode; when the screen displays content of the game / audio-visual entertainment type and the display parameter is the color threshold, the current color gamut mode can be switched to the wide color gamut mode.

[0048] In some embodiments, when the electronic device recognizes that the overall color of the display content on the screen changes, a display adjustment event can be triggered.

[0049] In the embodiments of the present application, after the display adjustment event is triggered, the parameter adjustment information of the display parameter can be determined based on the event type of the display adjustment event.

[0050] Exemplarily, when the event type of the display adjustment event indicates that the gamma value is adjusted based on the current ambient light information, the parameter adjustment information of the gamma value can be determined based on the current ambient light information; when the event type of the display adjustment event indicates that the system of the electronic device enters the power-saving mode, the change in the color threshold before and after color gamut calibration can be determined as the parameter adjustment information of the display parameter.

[0051] In some embodiments, when the display adjustment event is triggered by the user's adjustment of the display parameter based on the adjustment control or adjustment button of the display, the parameter adjustment information of the display parameter can be determined based on the triggering situation of the adjustment control or adjustment button.

[0052] In the embodiments of the present application, step S101 can be executed by a processor in an electronic device. Exemplarily, the processor can be a Central Processing Unit (CPU). After determining the parameter adjustment information of the display parameters, the CPU can send the parameter adjustment information of the display parameters to a Timing Controller (TCON).

[0053] Step S102, based on the change parameter of the transmittance of the screen, determine the first brightness adjustment strategy of the screen; the change parameter of the transmittance is the change information of the transmittance when adjusting the display parameters using the parameter adjustment information.

[0054] In the embodiments of the present application, the change parameter of the transmittance when adjusting the display parameters using the parameter adjustment information can be predicted first, and then based on the change parameter of the transmittance of the screen, the first brightness adjustment strategy of the screen can be determined.

[0055] In the embodiments of the present application, the change parameter of the transmittance of the screen can be determined through the screen material parameters of the screen.

[0056] In some embodiments, the change parameter of the transmittance of the screen can also be determined based on the parameter adjustment information of the display parameters.

[0057] In the embodiments of the present application, the brightness of the screen is inversely proportional to the transmittance of the screen.

[0058] It can be understood that the purpose of the parameter adjustment method provided in the embodiments of the present application is to reduce the rapid change of the brightness of the screen during the process of adjusting the display parameters. Therefore, when the transmittance of the screen changes due to the adjustment of the display parameters, it is necessary to adjust the brightness so that the brightness of the screen does not change from the user's perspective. Therefore, when the transmittance of the screen increases, if the brightness is not adjusted, the brightness of the screen will increase from the user's perspective, so the brightness needs to be reduced; when the transmittance of the screen decreases, if the brightness is not adjusted, the brightness of the screen will decrease from the user's perspective, so the brightness needs to be increased.

[0059] In the embodiments of the present application, step S102 can be executed by a processor in an electronic device. Exemplarily, the processor can be a CPU. After determining the first brightness adjustment strategy of the screen, the CPU can send the first brightness adjustment strategy of the screen to the TCON.

[0060] Step S103, based on the parameter adjustment information and the first brightness adjustment strategy, adjust the display parameters of the screen and the brightness of the screen.

[0061] In the embodiments of the present application, the processor may send the parameter adjustment information and the first brightness adjustment strategy determined by itself to the TCON in the screen. The TCON can synchronously adjust the display parameters and the brightness of the screen through the parameter adjustment information and the first brightness adjustment strategy.

[0062] In some embodiments, while adjusting the display parameters through the parameter adjustment information, the TCON can adjust the brightness of the screen based on the first brightness adjustment strategy through the backlight driving module, so as to synchronously adjust the display parameters and the brightness of the screen.

[0063] Exemplarily, when the color gamut standard of the electronic device is DCI-P3 or sRGB, when the color gamut calibration function is turned on, the transmittance of the screen is A, and when the color gamut calibration function is turned off, the transmittance of the screen is A * 94%. It can be seen that when the display parameters change, it will affect the transmittance of the screen, so that when the electronic device adjusts the display parameters, the screen changes and flickers quickly. Therefore, by determining the first brightness adjustment strategy of the screen through the change parameters of the transmittance of the screen and synchronously adjusting the brightness when adjusting the display parameters, it is possible to adjust the display parameters without the user noticing, thereby improving the user experience.

[0064] In the embodiments of the present application, the parameter adjustment information of the display parameters is determined through the display adjustment event for the display parameters of the screen; then, based on the change parameters of the transmittance of the screen when the parameter adjustment information is used to adjust the display parameters, the first brightness adjustment strategy of the screen is determined; finally, based on the parameter adjustment information and the first brightness adjustment strategy, the display parameters and the brightness of the screen are adjusted. In this way, because the first brightness adjustment strategy is determined based on the change parameters of the transmittance of the screen when the parameter adjustment information is used to adjust the display parameters, it is possible to make up for the brightness change of the screen due to the adjustment of the display parameters when adjusting the display parameters based on the parameter adjustment information, so as to adjust the display parameters without the user noticing, thereby improving the user experience.

[0065] In some embodiments, as Figure 2 shown, the above parameter adjustment method includes step S201 and step S202, and the above step S103 can be implemented through step S203:

[0066] Step S201, in response to the brightness adjustment event for the screen, determine the second brightness adjustment strategy of the screen.

[0067] In the embodiments of the present application, the brightness adjustment event may be triggered by the user's adjustment of the brightness based on the brightness adjustment control or the brightness adjustment button of the display.

[0068] In some embodiments, the brightness adjustment event may also be automatically triggered by the electronic device.

[0069] In an embodiment of the present application, when the brightness adjustment event is triggered by a user's adjustment of the brightness using the brightness adjustment control or the brightness adjustment button of the display, the second brightness adjustment strategy of the brightness can be determined based on the triggering situation of the brightness adjustment control or the brightness adjustment button.

[0070] In an embodiment of the present application, after determining the second brightness adjustment strategy of the screen, the CPU can send the second brightness adjustment strategy to the TCON.

[0071] Step S202: Determine the target brightness adjustment strategy of the screen based on the second brightness adjustment strategy and the first brightness adjustment strategy.

[0072] In an embodiment of the present application, after receiving the first brightness adjustment strategy determined based on the display adjustment event and the second brightness adjustment strategy determined based on the brightness adjustment event, the TCON can fuse the second brightness adjustment strategy and the first brightness adjustment strategy to obtain the final target brightness adjustment strategy.

[0073] In some embodiments, the second brightness adjustment strategy and the first brightness adjustment strategy can be superimposed to obtain the target brightness adjustment strategy. Exemplarily, when the second brightness adjustment strategy indicates a 10% increase in brightness and the first brightness adjustment strategy indicates a 6% increase, the target brightness adjustment strategy indicating a 16% increase in brightness can be finally obtained.

[0074] Step S203: Adjust the display parameters and the brightness of the screen based on the parameter adjustment information and the target brightness adjustment strategy.

[0075] In an embodiment of the present application, after determining the target brightness adjustment strategy, the display parameters and the brightness of the screen can be synchronously adjusted based on the parameter adjustment information and the target brightness adjustment strategy.

[0076] In an embodiment of the present application, by fusing the second brightness adjustment strategy of the screen determined based on the brightness adjustment event for the screen and the first brightness adjustment strategy based on the display adjustment event for the display parameters of the screen, it is possible to take into account the brightness adjustment of the display adjustment event while adjusting the brightness in response to the brightness adjustment event, and thus not only meet the user's brightness adjustment requirements, but also compensate for the brightness change of the screen due to the adjustment of the display parameters.

[0077] In some embodiments, before step S102, the above parameter adjustment method can also be implemented through at least one of the following steps:

[0078] Step 11: Determine the change parameter of the transmittance of the screen based on the screen material parameters of the screen.

[0079] Here, the screen material parameters of the screen can be the material characteristic parameters of the filter of the screen. It can be understood that for filters of different materials, when the parameters are adjusted, the transmittance of the screen will change differently. Therefore, the change parameters of the transmittance of the screen can be determined through the screen material parameters.

[0080] In some embodiments, the correspondence between the transmittance of the screen and the display parameters can be determined based on the screen material parameters; based on the parameter adjustment information, the change parameters of the transmittance of the screen before and after the adjustment of the display parameters can be determined in the correspondence between the transmittance of the screen and the display parameters.

[0081] Step 12, determine the change parameters of the transmittance of the screen based on the parameter adjustment information of the display parameters.

[0082] In the embodiments of the present application, the change parameters of the transmittance of the screen when the display parameters are adjusted differently can be determined in advance through the test of the amount of outgoing photons and the amount of incident photons of the screen. Then, the change parameters of the transmittance of the screen are determined through the parameter adjustment information of the display parameters.

[0083] In some embodiments, as Figure 3 shown, step S102 can be implemented through step S301 and step S302:

[0084] Step S301, when the change parameter indicates that the transmittance of the screen decreases, determine the first brightness adjustment strategy for increasing the brightness of the screen.

[0085] Step S302, when the change parameter indicates that the transmittance of the screen increases, determine the first brightness adjustment strategy for decreasing the brightness of the screen.

[0086] Among them, the degree of change of the transmittance corresponds to the degree of change of the brightness of the screen.

[0087] It can be understood that the transmittance refers to the proportion (expressed as a percentage) of light that the screen allows to pass through. For example, a transmittance of 80% means that 80% of the light can pass through the screen, and the remaining 20% is absorbed or reflected. The actual brightness of the screen is determined by the luminous intensity of the screen itself (such as the brightness of the backlight) and the transmittance of the screen (which affects the amount of light finally emitted). Therefore, when the luminous intensity of the screen itself remains unchanged, if the transmittance of the screen decreases, the actual brightness of the screen decreases. In order to adjust the display parameters without the user noticing, it is necessary to increase the luminous intensity of the screen, that is, to determine the first brightness adjustment strategy for increasing the brightness of the screen. Similarly, when the luminous intensity of the screen itself remains unchanged, if the transmittance of the screen increases, the actual brightness of the screen increases. In order to adjust the display parameters without the user noticing, it is necessary to decrease the luminous intensity of the screen, that is, to determine the first brightness adjustment strategy for decreasing the brightness of the screen.

[0088] In the embodiments of the present application, the degree of change in the transmittance corresponds to the degree of change in the brightness of the screen. Because the change parameter of the transmittance is determined based on the parameter adjustment information of the display parameters, the degree of change in the brightness of the screen corresponds to the degree of adjustment of the display parameters. This can improve the consistency between the brightness adjustment of the screen and the adjustment of the display parameters, so as to more smoothly adjust the display parameters without the user noticing.

[0089] In some embodiments, as Figure 4a shown, the above step 11 can be implemented through step S401 and step S402:

[0090] Step S401, based on the screen material parameters, determine the corresponding relationship between the transmittance of the screen and the display parameters.

[0091] It can be understood that the processor stores a database corresponding to different screen material parameters, and this database stores the corresponding relationship between the transmittance of the screen and the display parameters corresponding to the screen material parameters. Therefore, when the screen material parameters are obtained, the corresponding database can be determined.

[0092] Step S402, based on the parameter adjustment information, determine the change parameter of the transmittance of the screen before and after the adjustment of the display parameters in the corresponding relationship between the transmittance of the screen and the display parameters.

[0093] Exemplarily, as Figure 4b shown, the abscissa is the values of each display parameter ( Figure 4b the shown display parameters are color gamut, gray scale, and gamma), and the ordinate is the transmittance of the screen. Through the Figure 4b shown curve graph, the change parameter of the transmittance of the screen before and after the adjustment of the display parameters can be determined.

[0094] In some embodiments, the parameter adjustment information represents the adjustment from a first display parameter to a second display parameter; the first brightness adjustment policy represents the adjustment from a first brightness to a second brightness; as Figure 5a shown, the above step S103 can be implemented by step S501 and step S502:

[0095] Step S501, through the timing control unit in the screen, while adjusting the first display parameter to the second display parameter, send a first brightness adjustment signal representing the adjustment from the first brightness to the second brightness to the backlight driving module in the screen.

[0096] Step S502, through the backlight driving module, in response to the first brightness adjustment signal, adjust the first brightness to the second brightness.

[0097] Here, the first brightness adjustment signal can be a Pulse Width Modulation Signal (PWM) signal.

[0098] In the embodiments of the present application, the PWM signal is a square wave signal from 0% to 100%, 0% corresponds to a brightness of 0 nit, 100% corresponds to the maximum brightness of the screen, and there is a linear relationship in between. Therefore, the backlight driving module can be controlled by the PWM signal to adjust the screen brightness. Exemplarily, as Figure 5b shown, the PWM signal has a linear positive proportional relationship with the screen brightness.

[0099] In the embodiments of the present application, the timing control unit sends a first brightness adjustment signal to the backlight driving module in the screen while adjusting the display parameters, so that the display parameters and the brightness can be adjusted simultaneously.

[0100] Exemplarily, before the display parameter adjustment, the current brightness of the screen is 100 nits (nit), the display parameter is adjusted from a to b, and the transmittance of the screen decreases by a%, for example, the current brightness of the screen will decrease to 95 nit. At this time, the timing control unit can send a 100% PWM signal to the backlight driving module while adjusting the display parameter from a to b, so as to increase the brightness of the screen to 100 nit, so that the brightness remains unchanged before and after the display parameter adjustment.

[0101] In the embodiments of the present application, through the timing control unit in the screen, while adjusting the first display parameter to the second display parameter, a first brightness adjustment signal indicating that the first brightness is adjusted to the second brightness is sent to the backlight driving module in the screen; through the backlight driving module, in response to the first brightness adjustment signal, the first brightness is adjusted to the second brightness. In this way, through the interaction between the backlight driving module and the timing control unit, it is possible to adjust the screen brightness while adjusting the display parameter, so as to adjust the display parameter without the user's perception, and further improve the user's adaptation experience.

[0102] In some embodiments, as Figure 6 shown, the above step S103 can be implemented through step S601 and step S602:

[0103] Step S601, based on the change parameter of the transmittance of the screen, synchronously adjust the parameter adjustment information and the first brightness adjustment strategy to obtain a parallel adjustment strategy.

[0104] Step S602, based on the parallel adjustment strategy, synchronously adjust the display parameter and the brightness.

[0105] In the embodiments of the present application, the adjustment time interval of the parameter adjustment information and the first brightness adjustment strategy can be determined based on the change parameter of the transmittance of the screen, and then based on the adjustment time interval, the display parameter and the brightness are synchronously adjusted. Among them, the change parameter of the transmittance of the screen is proportional to the adjustment time interval.

[0106] It can be understood that when the change parameter of the transmittance of the screen is small, it indicates that the change in brightness before and after the adjustment of the display parameter is small, so the display parameter and the brightness can be synchronously adjusted within a short time interval. When the change parameter of the transmittance of the screen is large, it indicates that the change in brightness before and after the adjustment of the display parameter is large, so the display parameter and the brightness need to be gradually adjusted over a long period of time.

[0107] In some embodiments, as Figure 7 shown, the above step S601 can be implemented through step S701 and step S702:

[0108] Step S701, based on the change parameter of the transmittance of the screen, perform a partitioning process on the parameter adjustment range corresponding to the parameter adjustment information and the brightness adjustment range corresponding to the first brightness adjustment strategy to obtain at least two adjustment steps.

[0109] In the embodiment of the present application, the step length of the adjustment step is determined based on the change parameter of the transmittance of the screen, and the parameter adjustment range corresponding to the logarithmic adjustment information of the step length is divided to obtain at least two parameter adjustment sub-ranges; the brightness adjustment range corresponding to the logarithmic adjustment information of the step length is divided to obtain at least two brightness adjustment sub-ranges; wherein, the number of the brightness adjustment sub-ranges is the same as that of the parameter adjustment sub-ranges. Then, at least two adjustment steps are determined based on the at least two parameter adjustment sub-ranges and the at least two brightness adjustment sub-ranges.

[0110] Exemplarily, when the change parameter of the transmittance of the screen is 6%, the parameter adjustment range can be divided into 6 parameter adjustment sub-ranges, and the brightness adjustment range can be divided into 6 brightness adjustment sub-ranges. Each adjustment step can include one parameter adjustment sub-range and one brightness adjustment sub-range, that is, the number of adjustment steps is 6; each adjustment step can also include two parameter adjustment sub-ranges and two brightness adjustment sub-ranges, that is, the number of adjustment steps is 3; each adjustment step can also include three parameter adjustment sub-ranges and three brightness adjustment sub-ranges, that is, the number of adjustment steps is 2.

[0111] It can be understood that in order to make the user feel the change of the screen brightness as much as possible when adjusting the display parameters, it is necessary to smoothly adjust the brightness and the display parameters. Therefore, the brightness adjustment range and the parameter adjustment range need to be divided according to the change parameter of the transmittance.

[0112] In the embodiment of the present application, the adjustment duration corresponding to each adjustment step is the same. That is to say, after each adjustment duration, one adjustment step is executed.

[0113] Step S702, determine the parallel adjustment strategy based on the at least two adjustment steps.

[0114] Wherein, each adjustment step corresponds to at least one parameter adjustment sub-range and at least one brightness adjustment sub-range; the parameter adjustment sub-range is the range obtained by dividing the parameter adjustment range; the brightness adjustment sub-range is the range obtained by dividing the brightness adjustment range.

[0115] In the embodiment of the present application, the at least two adjustment steps can be sorted according to the size relationship between the parameter adjustment sub-range and the brightness adjustment sub-range, and then the sorted at least two adjustment steps are sequentially executed in time order.

[0116] In the embodiments of the present application, based on the change parameter of the transmittance of the screen, the parameter adjustment range corresponding to the parameter adjustment information and the brightness adjustment range corresponding to the first brightness adjustment strategy are divided to obtain at least two adjustment steps; based on the at least two adjustment steps, a parallel adjustment strategy is determined. In this way, the adjustment process of the brightness and display parameters can be refined, so that the brightness and display parameters can be adjusted smoothly, thereby improving the user's adaptation experience.

[0117] In some embodiments, as Figure 8a shown, the above step S602 can be implemented through steps S801 to S804:

[0118] Step S801, use the start adjustment step among the at least two adjustment steps as the current adjustment step.

[0119] Here, the start adjustment step may refer to the adjustment step that includes the smallest parameter adjustment sub-range and the largest brightness adjustment sub-range, or the largest parameter adjustment sub-range and the smallest brightness adjustment sub-range among the at least two adjustment steps. Among them, the smallest parameter adjustment sub-range includes the smallest display parameter in the parameter adjustment range, the largest parameter adjustment sub-range includes the largest display parameter in the parameter adjustment range, the smallest brightness adjustment sub-range includes the smallest brightness in the brightness adjustment range, and the largest brightness adjustment sub-range includes the largest brightness in the brightness adjustment range.

[0120] Exemplarily, when the display parameter is adjusted from small to large, causing the transmittance of the screen to increase, the brightness needs to be adjusted from high brightness to low brightness. Then the start adjustment step includes the smallest parameter adjustment sub-range and the largest brightness adjustment sub-range; similarly, when the display parameter is adjusted from large to small, causing the transmittance of the screen to decrease, the brightness needs to be adjusted from low brightness to high brightness. Then the start adjustment step includes the largest parameter adjustment sub-range and the smallest brightness adjustment sub-range. That is to say, the parameter adjustment sub-range and the brightness adjustment sub-range included in the start adjustment step are both the starting adjustment sub-ranges of the parameter adjustment range and the brightness adjustment range.

[0121] Step S802, through the timing control unit in the screen, based on the parameter adjustment sub-range in the current adjustment step, adjust the display parameter, and send a second brightness adjustment signal corresponding to the brightness adjustment sub-range in the current adjustment step to the backlight driving module in the screen.

[0122] In the embodiments of the present application, the timing control unit can adjust the display parameter according to the parameter adjustment sub-range in the current adjustment step, and then while adjusting the display parameter, send a second brightness adjustment signal corresponding to the brightness adjustment sub-range in the current adjustment step to the backlight driving module.

[0123] Step S803: In response to the first brightness adjustment signal, the backlight driving module adjusts the brightness based on the brightness adjustment sub-range in the current adjustment step.

[0124] Step S804: Use the adjustment steps that are adjacent to the current adjustment step in terms of execution time among at least two adjustment steps as the current adjustment step, and repeat the above steps until all adjustment steps are completed.

[0125] In the embodiment of the present application, after the start adjustment step is completed, the adjustment steps that are adjacent to the current adjustment step in terms of execution time are executed.

[0126] The following uses Figure 8b and Figure 8c to illustrate the implementation manners of steps S801 to S804:

[0127] As Figure 8b shown, curve 801 is the change curve of the change value of the transmittance of the screen, and curve 802 is the change curve of the change value of the brightness adjustment signal. Among them, the abscissa is time (s), the positive ordinate is the change value of the transmittance of the screen, and the negative ordinate is the change value of the brightness adjustment signal. It can be seen that due to the adjustment of the display parameters, the transmittance of the screen increases by 6% within 7s. Therefore, in order to make the user not feel the adjustment of the display parameters, the brightness needs to be reduced by 6% within 7s. That is to say, the adjustment time of the display parameters is the same as the adjustment time of the brightness, both are 7s.

[0128] As Figure 8c shown, straight line 803 is the change straight line of the actual brightness value of the screen, straight line 804 is the change curve of the brightness adjustment signal; straight line 805 is the change curve of the transmittance of the screen. Among them, the abscissa is time (s), the left ordinate is the actual brightness value, and the right ordinate is the transmittance of the screen. From Figure 8c it can be seen that the adjustment duration of at least two adjustment steps is 6s, the adjustment duration of each adjustment step is 1s, the transmittance of the screen gradually increases, that is, the display parameters gradually increase, while the brightness adjustment signal gradually decreases. Therefore, in each second's adjustment step, the display parameters and the brightness are adjusted simultaneously. Finally, it can be seen from straight line 803 that the actual brightness of the screen has not changed, that is, the adjustment of the display parameters is completed without the user feeling it.

[0129] In the embodiment of the present application, the adjustment steps are executed in sequence according to the execution time, and the brightness and display parameters are adjusted simultaneously in the adjustment steps, so as to smoothly adjust the brightness and display parameters, thereby improving the user's adaptation experience.

[0130] The following illustrates the application of the parameter adjustment method provided by the embodiment of the present application in an actual scenario:

[0131] Currently, adjusting the brightness of a laptop screen is achieved through the operating system and display driver. Moreover, many screens support Wide Color Gamut (WCG) and multi-color gamut switching. Before and after the color gamut switching of the screen, the transmittance of the liquid crystal panel will vary, resulting in inconsistent brightness performance. However, the system does not control this part of the brightness difference caused by color gamut switching, and the system and driver levels cannot control and respond immediately, thus causing the brightness to change rapidly and flicker due to the change of color gamut parameters, affecting the user experience. At the same time, parameters such as the gray scale and Gamma curve of the screen display will also affect the backlight brightness. If these parameters change suddenly, it will also cause the screen brightness to flicker.

[0132] Adjusting the backlight brightness through different color gamut ranges of the same screen can save up to 5-10% of the backlight power consumption at most, and at the same time, it can reduce the brightness mutation during the color gamut switching process, affecting the user experience.

[0133] To solve the above problems, an embodiment of the present application provides a parameter adjustment method, which can be implemented through steps S901 to S904:

[0134] Step S901, when the system enters the power-saving mode and the color gamut calibration function is turned off, the system-side software sends a command for changing the color gamut to the TCON of the screen.

[0135] It can be understood that the relationship between the backlight transmittance of the screen and the color gamut change is affected by the material characteristics of the screen itself, such as the characteristics of the color filter. When the change before and after color gamut calibration is large, the change in backlight transmittance is also large. Therefore, the influence of different screen backlight transmittances (the change rate of screen backlight transmittance) needs to be obtained through actual tests.

[0136] Exemplarily, as Figure 9a shown, under the color gamut standard sRGB, before the system enables color gamut calibration, the color gamut value is A, and after enabling color gamut calibration, the color threshold A becomes color threshold B. Therefore, when the color gamut calibration function in the system is turned off, the color threshold of the screen changes, thereby causing the change of the transmittance of the screen, and further causing the change of the brightness of the screen.

[0137] As Figure 9b shown, the screen brightness before color gamut calibration is greater than the screen brightness after color gamut calibration. The reason is that: before and after color gamut calibration, the color gamut value of the screen changes, thereby affecting the transmittance of the screen, and further causing the change of the screen brightness before and after color gamut calibration. Among them, the measured influence on the backlight transmittance of the screen under the DCIP3 and sRGB color gamuts before and after color gamut calibration is 6%.

[0138] In step S902, the TCON determines the change rate of the screen backlight transmittance in the database according to the parameters before and after the color gamut change.

[0139] In step S903, the TCON outputs the change rate of the transmittance corresponding to the color gamut parameters to the backlight driving IC according to the change of different dimming signals.

[0140] In step S904, the TCON aligns or extends the time interval of the change of the duty cycle of the dimming signal and the time interval of the color gamut change, so as to automatically adjust the backlight brightness while the color gamut changes.

[0141] In the embodiment of the present application, when the color gamut value needs to be adjusted from A to B, the adjustment process can be evenly divided into 6 small changes. The change of the backlight transmittance corresponding to each color gamut change is 1%. At the same time, each change interval is 1 second, so that the original one-step color gamut adjustment completed in one frame (16 ms) becomes 5 steps. On this basis, through the PWM duty cycle signal output by the TCON, the backlight brightness is adjusted reversely. While the backlight brightness is slowly adjusted, the backlight brightness before and after the color gamut adjustment remains unchanged.

[0142] In the embodiment of the present application, on the current backlight brightness of the dynamically adjusted color gamut, the duty cycle of the 6% PWM signal is reduced, also 1% is reduced every 1 second, and the brightness compensation adjustment is completed after 5 seconds. The overall scheme is shown in the following figure. By slowing down the brightness change and corresponding PWM compensation, the actual brightness seen by the user remains unchanged.
