[0034] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.
[0035] The display adjustment method provided by the embodiment of the present disclosure is applied to a scenario in which the display brightness of a display device is adjusted when the temperature of the display device rises.
[0036] Screen display technology is an essential technical function for smart display terminals. It is currently used in various display devices, including Thin Film Transistor Liquid Crystal Display (TFT-LCD) screen displays. The TFT-LCD screen places liquid crystal between two pieces of conductive glass, and relies on the electric field between two electrodes to drive the liquid crystal molecules to twist the electric field effect to control the transmission of the light source, produce light and dark changes between the power switch, and thus display the image. TFT-LCD screen display technology requires backlight control to adjust the screen backlight brightness, and then the brightness of the screen display. In the daily use of the display device, continuous use of the display device or long-term use of the display device in a high temperature environment will cause the display device temperature to rise, which will cause the terminal to be significantly stuck, affecting the user experience and grip feel.
[0037] In the related art, when the temperature of the display device is too high, the built-in temperature control strategy of the display device will be triggered. The purpose of the temperature control strategy is to reduce the temperature of the display device, and reduce the power consumption of the screen display module by reducing the backlight brightness of the display screen of the display device. However, the reduction of the backlight brightness of the display device will cause the display brightness of the display device to be reduced synchronously, which in turn affects the display effect of the display device, causing the user to be unable to see the display content of the display device clearly, affecting the user's experience.
[0038] In view of this, the present disclosure proposes a display adjustment method, which adjusts other display parameters of the display device while adjusting the backlight brightness due to the increase in temperature, resulting in a decrease in display brightness. By adjusting other display parameters while adjusting the display brightness, the problem of poor display quality of the display device when the device temperature increases is solved, and the quality of the displayed content is improved.
[0039] Figure 1 FIG. 1 is a flow chart showing a display adjustment method according to an exemplary embodiment. Figure 1 As shown, the method includes step S101 to step S102.
[0040] In step S101 , the current backlight brightness of the display device is adjusted according to the current device temperature of the display device.
[0041] In step S102, in response to adjusting the current backlight brightness, the target display parameter is adjusted according to the association between the target display parameter and the backlight brightness of the display device.
[0042] In the disclosed embodiment, when the display device is in the screen-on use state, the mainboard temperature monitoring service (thermal) of the display device continuously monitors the current temperature of the mainboard of the display device. When the mainboard temperature is higher than a certain temperature value, the temperature adjustment strategy is activated to reduce the mainboard temperature by reducing the backlight brightness of the display screen, and adjust other display parameters (target display parameters) of the display device while reducing the backlight brightness. By adjusting other display parameters of the display device while reducing the backlight brightness, the display effect of the display device is guaranteed when the display brightness decreases, so that the user can see the display content clearly even when the display brightness of the display device decreases.
[0043] In an embodiment of the present disclosure, when adjusting the backlight brightness according to the device temperature of the display device, it is necessary to determine a temperature threshold corresponding to the current device temperature, and then adjust the backlight brightness according to the relationship between the determined temperature threshold and the current device temperature. The following embodiment of the present disclosure further explains the method for adjusting the current backlight brightness of the display device.
[0044] Figure 2 FIG. 1 is a flow chart showing a method for adjusting the current backlight brightness of a display device according to an exemplary embodiment. Figure 2 As shown, the method includes step S201, step S202A, step S202B and step S202C.
[0045] In step S201, the current backlight brightness of the display device is determined, and a backlight brightness threshold corresponding to the current device temperature is determined.
[0046] Among them, the backlight brightness threshold is used to maintain the device temperature of the display device.
[0047] In step S202A, in response to the current backlight brightness being less than the backlight brightness threshold, the current backlight brightness is maintained.
[0048] In the embodiments of the present disclosure, different backlight brightness thresholds are set for different device temperature ranges. It is understandable that the higher the backlight brightness of the device, the higher the power consumption of the backlight display module of the device, which leads to a higher temperature of the device. Based on the positive correlation between the backlight brightness of the device and the temperature of the device, the present disclosure sets a lower backlight brightness threshold for a higher device temperature and a higher backlight brightness threshold for a lower device temperature.
[0049] In the disclosed embodiment, when the current backlight brightness is less than the backlight brightness threshold corresponding to the current device temperature, it indicates that the power consumption of the current backlight display module meets the requirements and will not cause the device temperature to rise, thereby affecting the user experience. In this case, the current backlight brightness is maintained.
[0050] In an exemplary embodiment of the present disclosure, the backlight brightness threshold corresponding to the current device temperature of the display device is 500 levels. If it is determined that the current backlight brightness of the display device is 450 levels<500 levels, the backlight brightness of the display device is not adjusted.
[0051] In step S202B, in response to the current backlight brightness being greater than the backlight brightness threshold and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold being less than the preset brightness value, the current backlight brightness is maintained.
[0052] In the disclosed embodiment, there is a large difference between the minimum backlight brightness of the display device under temperature control and the maximum backlight brightness supported by the display device. If the backlight brightness is adjusted with the minimum brightness unit during brightness adjustment, it will cause the device processor to have too much computational effort. Therefore, the brightness is adjusted with the preset brightness value as the unit adjustment value during scheduling adjustment, where the preset brightness value is an integer multiple of the unit brightness value. When the current backlight brightness is greater than the backlight brightness threshold, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is less than the preset brightness value, the influence of the power consumption of the backlight display module on the device temperature can be ignored, and the difference between the current backlight brightness and the backlight brightness threshold does not meet the preset brightness value as the unit adjustment value, so the backlight brightness of the display device is not adjusted.
[0053] In an exemplary embodiment of the present disclosure, the backlight brightness threshold corresponding to the current device temperature of the display device is 500 steps, and the preset brightness value is 10 steps. If it is determined that the current backlight brightness of the display device is 505 steps> 500 steps, but the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is 5 steps< 10 steps, the backlight brightness of the display device is not adjusted.
[0054] In step S202C, in response to the current backlight brightness being greater than the backlight brightness threshold and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold being greater than the preset brightness value, the current backlight brightness is adjusted according to the difference and the preset brightness value.
[0055] In the embodiment of the present disclosure, when the current backlight brightness is greater than the backlight brightness threshold, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is greater than the preset brightness value, it is characterized that the power consumption of the backlight display module of the display device is higher than the current power consumption requirement, and it is necessary to reduce the power consumption of the backlight display module by reducing the backlight brightness, thereby reducing the device temperature of the display device.
[0056] In an exemplary embodiment of the present disclosure, the backlight brightness threshold corresponding to the current device temperature of the display device is 500 steps, and the preset brightness value is 10 steps. If it is determined that the current backlight brightness of the display device is 545 steps> 500 steps, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is 45 steps< 10 steps, the backlight brightness of the display device is adjusted.
[0057] In the disclosed embodiment, corresponding backlight brightness thresholds are set for different device temperature ranges. After determining the current temperature of the device, the backlight brightness threshold corresponding to the current device temperature is determined, and when the current backlight brightness is greater than the backlight brightness threshold, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is greater than a preset brightness value, the backlight brightness of the display device is adjusted, thereby reducing the power consumption of the backlight display module, achieving the purpose of reducing the device temperature, and further improving the user experience.
[0058] In the embodiments of the present disclosure, when adjusting the backlight brightness of a display device, in order to avoid a sudden change in the display brightness of the display device affecting the viewing experience of the user when using the display device, the backlight brightness of the display device needs to be gradually adjusted in stages so that the display brightness of the display device changes smoothly. The following embodiments of the present disclosure further illustrate the adjustment of the backlight brightness of a display device.
[0059] Figure 3 FIG. 1 is a flow chart showing a method for adjusting the current backlight brightness according to a difference value and a preset brightness value according to an exemplary embodiment. Figure 3 As shown, the method includes step S301 to step S302.
[0060] In step S301, the quotient of the difference value and the preset brightness value is rounded down to determine the number of adjustments.
[0061] In step S302, according to the number of adjustments, the value is adjusted in units of a preset brightness value, and the current backlight brightness is adjusted unit by unit toward the backlight brightness threshold value.
[0062] In the disclosed embodiment, when the current backlight brightness is greater than the backlight brightness threshold, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is greater than the preset brightness value, the number of adjustments is set according to the difference and the preset brightness value, and the quotient of the difference and the preset brightness value is rounded down as the number of adjustments. Then, the backlight brightness of the display device is adjusted in stages, so that the backlight brightness of the display device smoothly transitions and is adjusted in the direction of the backlight brightness threshold, so that the current backlight brightness is less than or equal to the backlight brightness threshold, or the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is less than the preset brightness value.
[0063] In an exemplary embodiment of the present disclosure, the backlight brightness threshold corresponding to the current device temperature of the display device is 500 steps, and the preset brightness value is 10 steps. It is determined that the current backlight brightness of the display device is 545 steps>500 steps, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is 45 steps<10 steps, then the quotient of the difference and the preset brightness value is rounded down to determine the number of adjustments as 4 times, and the backlight brightness of the display device is adjusted in 4 times, each time decreasing by 10 steps, and the backlight brightness of the display device is adjusted to 505 steps.
[0064] In the embodiment of the present disclosure, the target display parameter of the display device is adjusted while adjusting the backlight brightness of the display device, so the target display parameter is adjusted each time the backlight brightness is adjusted during the staged adjustment of the backlight brightness of the display device. The following embodiment of the present disclosure describes the method for adjusting the display parameter.
[0065] Figure 4 FIG. 1 is a flow chart showing a method for adjusting target display parameters according to an exemplary embodiment. Figure 4 As shown, the method includes step S401 to step S402.
[0066] In step S401, according to the number of adjustments, the value is adjusted in units of a preset brightness value, and the current backlight brightness is adjusted unit by unit toward the backlight brightness threshold value.
[0067] In step S402, in the process of adjusting the current backlight brightness unit by unit by adjusting the value in units of the preset brightness value, the target display parameter is adjusted.
[0068] In the embodiment of the present disclosure, when the current backlight brightness is greater than the backlight brightness threshold, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is greater than the preset brightness value, when the backlight brightness is adjusted in stages, the target display parameter is adjusted each time the backlight brightness is adjusted. It is ensured that the display device has a good display effect during the backlight brightness adjustment process, so that the user can clearly see the display content of the display device, and the user experience is guaranteed.
[0069] In the embodiment of the present disclosure, the correlation between the target display parameter and the backlight brightness is predetermined, and under the corresponding target display parameters and backlight brightness, the display device has a relatively good display effect. The following embodiment of the present disclosure describes a method for determining the correlation between the target display parameter and the backlight brightness.
[0070] Figure 5 FIG. 1 is a flow chart showing a method for determining an association relationship between a target display parameter and backlight brightness of a display device according to an exemplary embodiment. Figure 5 As shown, the method includes step S501 to step S502.
[0071] In step S501 , the minimum adjusted backlight brightness of the display device is determined, and the maximum backlight brightness of the display device is determined.
[0072] In step S502, a target display parameter corresponding to each preset brightness value between the minimum adjusted backlight brightness and the maximum backlight brightness is determined.
[0073] In the disclosed embodiment, the minimum adjusted backlight brightness of the display device is higher than the minimum brightness supported by the display device, which is the minimum backlight brightness supported by the temperature control strategy after the device turns on temperature control. At this backlight brightness, the display device still has a considerable display brightness, and the display effect still supports user viewing. The maximum backlight brightness of the display device is also the highest backlight brightness supported by the temperature control strategy. When the display device adjusts the backlight brightness through temperature control, it adjusts the value in units of the above-mentioned preset brightness value (such as 10-step brightness). To ensure that each brightness adjustment has a corresponding target display parameter, the corresponding target display parameter is set for each interval of the preset brightness value between the minimum adjusted backlight brightness and the maximum backlight brightness. It can be understood that under the corresponding target display parameters and backlight brightness, the display device has a relatively good display effect, which can ensure that the user can clearly see the display content of the display device.
[0074] In an exemplary embodiment of the present disclosure, the following method is used to determine the correlation between the target display parameters and the backlight brightness of the display device: first set the minimum brightness value of the display device under temperature control, and fix the screen display brightness of the display device to the minimum brightness value. Confirm the maximum brightness value supported by the screen with the display driver chip (Display Driver Integrated Circuit, DDIC) supplier. By software, write the backlight value to the control backlight node, add 10 steps of backlight value to the minimum brightness value, use a color analyzer (such as CA410) for testing, and obtain the display brightness value and gamma value that characterize the screen display effect at the minimum brightness value and after adding 10 steps of backlight brightness, respectively, as a comparison machine; on the test machine, write the minimum brightness value and the brightness value after adding 10 steps, debug the target display parameters of the display device at each brightness value, and determine the corresponding display brightness value and gamma value, and compare them with the display brightness value and gamma value in the comparison machine until the best target display parameters are obtained, and the best target display parameters and corresponding brightness have the best display effect. Write the best target display parameters into the register parameters of DDIC. Add 10 levels of backlight values and determine the process of the best target display parameters, debug the register parameters of all groups of DDIC from the minimum brightness value to the maximum brightness, and record them in a table as the correlation between the target display parameters and the backlight brightness.
[0075] In the embodiment of the present disclosure, the target display parameter is a display parameter other than display brightness that affects the display effect. The following embodiment of the present disclosure describes the target display parameter.
[0076] In one implementation of the disclosed embodiment, the target display parameter includes at least one of saturation, contrast and hue.
[0077] In the embodiment of the present disclosure, when determining the correlation between the target display parameters and the backlight brightness, after completing the backlight value setting, the saturation, contrast and hue of the display device are debugged until the optimal saturation, contrast and hue combination is obtained as the target display parameter.
[0078] The following embodiments of the present disclosure further illustrate the method for adjusting the backlight brightness.
[0079] In one implementation of the disclosed embodiment, in the process of adjusting the current backlight brightness unit by unit with the preset brightness value as the unit adjustment value, a preset time value is separated between two adjacent brightness adjustments.
[0080] In the disclosed embodiment, by setting a preset time value between two adjacent brightness adjustments, the display brightness of the display device changes more smoothly, reducing the user's perception of brightness changes and improving the viewing experience when using the display device.
[0081] In an exemplary embodiment of the present disclosure, Figure 6 As shown in the flowchart of the display adjustment method, the backlight brightness of the display device is adjusted in the following manner: the temperature control detects the current motherboard temperature and reports it to the display adjustment (display) service, the display adjustment service detects the current backlight brightness, and selects the brightness threshold corresponding to the current motherboard temperature according to the established backlight strategy, and at the same time obtains the current user-set backlight brightness, compares the backlight threshold with the current backlight brightness, calculates the difference, selects from the pre-set backlight brightness-display parameter correspondence table, selects the display parameters that meet the current backlight brightness (pre-adjusted saturation, contrast and hue parameters), and then sets them together with the backlight brightness value in a step-by-step setting (dimming) manner, gradually adjusts the backlight brightness and the corresponding display parameters, reduces the power consumption of the backlight, enables the motherboard to achieve cooling operation, and ensures the display effect to meet the user's experience.
[0082] In an exemplary embodiment of the present disclosure, Figure 7As shown in the flowchart of the method for display adjustment using a step-by-step setting method, the backlight brightness and display parameters of the display device are adjusted in the following manner: the current backlight brightness and the current device temperature are detected by the backlight strategy of the motherboard temperature monitoring service; the backlight value that limits the device temperature under the current device temperature, i.e., the backlight threshold, is confirmed and recorded as target_brightness. The current backlight node value of the display device at this time is read by software and recorded as current_brightness. The difference between the current backlight brightness and the backlight threshold, diff_brightness = target_brightness-current_brightness, is calculated. If the difference is less than 0, the backlight value of the display device is not adjusted. If the difference is greater than 0, the quotient count value of the difference and 10, i.e., the adjustment value (the 10-order brightness value is the unit adjustment value when the brightness is adjusted), is calculated. If the count value, i.e., the adjustment value, is less than 1, the backlight value of the display device is not adjusted. If the count value, i.e., the adjustment value, is greater than 1, then set the count times, i.e., the number of adjustments (difference / 10, and round down), adjust the value in units of 10-step brightness values, adjust the backlight brightness of the display device unit by unit, and reduce the brightness value of count*10 on the current backlight value. At the same time, select the display driver chip parameters (including saturation, contrast, and hue parameters) corresponding to the brightness after each adjustment from the recorded pre-set backlight brightness-display parameter correspondence table, and set them together in the display driver chip. When setting the brightness value and the display driver chip parameter value for adjacent times, a delay of 1 second is required in between to ensure that the user does not feel it obviously.
[0083] In the embodiment of the present disclosure, the correlation between the target display parameter (including at least one of saturation, contrast and hue) and the backlight brightness is determined in advance: the minimum backlight brightness of the display device and the maximum backlight brightness supported by the display device are determined, and the target display parameter corresponding to the brightness of each interval of the preset brightness value between the minimum backlight brightness and the maximum backlight brightness is determined. In the actual use of the display device, the current backlight brightness and the current device temperature of the display device are monitored to determine the backlight brightness threshold corresponding to the current device temperature. When the current backlight brightness is greater than the backlight brightness threshold corresponding to the current device temperature, and the absolute value of the difference between the current backlight brightness and the backlight brightness threshold is greater than the preset brightness value, the backlight brightness and the target display parameter of the display device are adjusted: the quotient of the difference and the preset brightness value is rounded down to determine the number of adjustments, the preset brightness value is used as the unit adjustment value, the interval between two adjacent brightness adjustments is a preset time value, and the current backlight brightness and the corresponding target parameter are adjusted unit by unit in the direction of the backlight brightness threshold. Through the present disclosure, the problem of excessively high temperature of the mainboard is solved, the power consumption of the mobile phone at high temperature is reduced, and the battery life is improved. And the problem of poor display content quality of the display device when the device temperature rises is solved, and the display content quality is improved.
[0084] Based on the same concept, the embodiment of the present disclosure further provides a display adjustment device 100 .
[0085] It is understandable that the display adjustment device 100 provided in the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

In response to the current backlight brightness being less than the backlight brightness threshold, the current backlight brightness is maintained.
