The change of backlight dynamic adjustment factor can be adjusted in real time according to ambient light intensity, changes in display content, and temperature of the display screen. For example, when the ambient light is strong, the backlight dynamic adjustment factor will increase to increase the brightness; when the ambient light is weak, the backlight brightness will be reduced to reduce power consumption.

[0024] The present invention is further configured to establish a light source characteristic model of a glass-based fine-pitch display screen according to the current intensity of the input signal and the adjustment parameters of the backlight source, including: Obtaining the brightness output at the corresponding historical moment according to the current intensity of the historical input signal and the adjustment parameters of the historical backlight source; The current intensity of the historical input signal and the adjustment parameters of the historical backlight source are used as independent variables, and the brightness output at the corresponding historical moment is used as the dependent variable to construct a light source characteristic model for a small-pitch display screen based on a glass substrate. Specifically, the light source characteristic model is a mathematical model established by analyzing the current intensity of the input signal and the adjustment parameters of the backlight source, as well as the relationship between them and the brightness output. The purpose of this model is to describe the brightness change of the small-pitch display screen under different input conditions, and to model it through historical data, so as to provide brightness prediction and optimization in real-time control. The constructed light source characteristic model usually uses polynomial regression, support vector machine (SVM), neural network and other methods to fit the relationship between independent variables and dependent variables. In this way, a mathematical model can be obtained so that when the input signal and backlight parameters are given, the corresponding brightness output can be predicted, and this is not limited here.

[0025] The present invention is further configured such that the operating parameters include: display brightness, operating temperature, panel voltage drop, pixel response delay, panel aging factor, optical uniformity factor and heat dissipation factor. Specifically, display brightness refers to the intensity of light output by the display screen, and operating temperature refers to the temperature of the display screen during normal operation; pixel response delay refers to the reaction time of a single pixel of the display screen to a change in the input signal, indicating the time interval from the change of the input signal to the pixel display result; the present invention is further configured such that the panel voltage drop is the voltage difference between the two ends of the display panel; the calculation logic of the panel aging factor is: ,in, is the panel aging factor, is the panel aging rate coefficient, For panel usage time, is the average operating temperature of the panel, is the standard operating temperature of the panel; the calculation logic of the optical uniformity factor is: ,in, is the optical uniformity factor, is the number of pixels; the calculation logic of the heat dissipation factor is: ,in, is the heat dissipation factor, is the thermal conductivity coefficient, is the heat dissipation area, is the maximum operating temperature, is the ambient temperature.

[0026] The present invention is further configured to calculate the multidimensional adjustment factor, including: A reference brightness mapping function is constructed according to the operating temperature, the panel voltage drop and the pixel response delay; the construction logic of the reference brightness mapping function is: ,in, is the reference brightness mapping function, is the panel voltage drop, is the pixel response delay, is the operating temperature, is the coupling index, is the magnification factor, is the modulation index; specifically, a reference brightness mapping function is constructed by combining the operating temperature, panel voltage drop, and pixel response delay. This function is used to describe the theoretical brightness mapping value of the display under specific conditions. Its construction logic involves modeling the mutual influence of temperature, panel voltage drop, and response delay, so as to obtain an accurate brightness prediction mapping value. The coupling index The value range is (0,1). The impact of response delay is usually nonlinear, and a larger delay will not multiply the impact. The value range is (0,1). The effect of temperature increase on brightness is exponential. At higher temperatures, the loss of the circuit will increase significantly. The modulation index The value range of is (0,2), which is used to control the response curve of brightness. By referring to the brightness mapping function, the brightness output of the display can be accurately predicted under different operating temperatures, voltage drops and response delays. By adjusting the parameters in the model, the brightness of the display can be changed more smoothly under different environments, reducing the fluctuation of the display effect caused by environmental changes (such as temperature and load). The reference brightness mapping deviation is calculated according to the reference brightness mapping function and the display brightness; the calculation logic of the reference brightness mapping deviation is: ,in, is the reference brightness mapping deviation, To display brightness, For display brightness The mapping function of the display brightness Reference brightness mapping value under , mapping is performed based on historical data; specifically, the above calculation logic is to determine the reference brightness mapping deviation by comparing the difference between the mapping value corresponding to the actual display brightness and the theoretical brightness (the brightness mapping value calculated based on temperature, voltage drop and response delay); It is a mapping function used to output the corresponding reference brightness value according to the display brightness. It is a prior art to predict the theoretical brightness under different display brightness based on regression analysis of historical data or other modeling methods. It will not be described in detail here. By calculating the reference brightness mapping deviation, the difference between the actual display brightness and the theoretical value can be effectively quantified, providing a basis for optimizing brightness adjustment and ensuring a more accurate display effect. The brightness compensation factor is calculated according to the reference brightness mapping deviation and the panel aging factor; the calculation logic of the brightness compensation factor is: ,in, is the brightness compensation factor, is the panel aging factor, The modulation aging influence coefficient is as follows: specifically, the brightness compensation factor is calculated according to the reference brightness mapping deviation and the panel aging factor. The above calculation logic adjusts the brightness output by referring to the brightness mapping deviation and takes into account the aging effect of the panel to ensure that the brightness of the display screen can remain stable after long-term use. The modulation aging influence coefficient The value range is (0.1,1); by calculating the brightness compensation factor, the brightness decay of the panel due to aging and other factors can be compensated, thereby ensuring the brightness stability of the display after long-term use; The power optimization factor is calculated according to the operating temperature, the optical uniformity factor and the heat dissipation factor; the calculation logic of the power optimization factor is: ,in, is the power optimization factor, is the optical uniformity factor, is the heat dissipation factor, is the heat dissipation factor influence index coefficient, is the optical uniformity influence index coefficient, is the temperature normalized modulation coefficient; specifically, the power optimization factor is calculated based on the operating temperature, optical uniformity factor and heat dissipation factor to measure the power consumption optimization requirements of the system under current conditions, reflecting the power optimization space of the display screen under given operating temperature, optical uniformity and heat dissipation capacity; the heat dissipation factor affects the index coefficient , Optical uniformity influence index coefficient and the temperature normalized modulation coefficient The value range is (0,1), which controls the influence of each factor on the power optimization factor. A higher coefficient means that the corresponding factor has a greater influence on the power optimization factor. By calculating the power optimization factor, it is possible to determine whether the display screen has excessive power consumption under specific environmental conditions, and adjust the working conditions to optimize the power as needed; The backlight dynamic adjustment factor is calculated according to the display brightness, the operating temperature and the panel voltage drop; the calculation logic of the backlight dynamic adjustment factor is: ,in, is the backlight dynamic adjustment factor, is the logarithmic conversion index of brightness, is the power exponent of voltage drop, is the modulation coefficient of temperature under backlight regulation. Specifically, the backlight dynamic regulation factor is calculated based on the display brightness, operating temperature and panel voltage drop. The backlight dynamic regulation factor determines the regulation intensity of the display backlight and reflects how the display adjusts its backlight brightness under different conditions to adapt to different brightness requirements, operating temperature and voltage conditions. The brightness logarithmic conversion index The value range is (0.1,1), which indicates the sensitivity of brightness change to backlight adjustment and the power exponent of voltage drop. The value range is (0.1,1), which is used to adjust the effect of voltage change on backlight brightness, and the modulation coefficient of temperature under backlight adjustment The value range is (0.1, 2), which is set according to the actual heat dissipation performance and environmental conditions of the display screen. There is no restriction on this here.

[0027] The present invention is further configured such that, when the brightness compensation factor is less than a preset brightness compensation threshold, brightness compensation is performed on the display brightness at the current moment until the reference brightness mapping deviation is less than a preset reference brightness mapping deviation threshold; specifically, when the brightness compensation factor is less than the preset brightness compensation threshold, the system will perform compensation according to the display brightness at the current moment until the reference brightness mapping deviation is less than the preset reference brightness mapping deviation threshold. The brightness compensation factor is mainly used to compensate for brightness deviations caused by display screen aging, environmental changes, etc.; and is used to ensure that when the display screen is aged or the external environment changes, the display brightness will not have excessive deviations, thereby improving the consistency of the display effect; When the power optimization factor is less than the preset power optimization threshold and the operating temperature is greater than the preset operating temperature threshold, the output power is reduced; specifically, when the power optimization factor is less than the preset power optimization threshold and the operating temperature is higher than the preset operating temperature threshold, the system will reduce the output power of the display. The power optimization factor measures the optimization requirements of the current power consumption of the display. A smaller value indicates that the current power consumption is lower and close to the optimal value. By reducing power output, unnecessary energy consumption is reduced, especially in high temperature environments, so as to improve the energy efficiency of the display and extend its service life; When the backlight dynamic adjustment factor is greater than the preset backlight dynamic adjustment threshold, the backlight brightness is reduced; specifically, when the backlight dynamic adjustment factor is greater than the preset backlight dynamic adjustment threshold, the system will reduce the backlight brightness. The backlight dynamic adjustment factor reflects the need for dynamic adjustment of the backlight brightness under different environments and conditions; it is used to reduce power consumption and improve display effects by dynamically adjusting the backlight brightness. When the backlight adjustment factor is too high, it means that the backlight brightness is too strong, which may cause energy waste, so the backlight brightness needs to be reduced; by dynamically adjusting the display brightness, power and backlight brightness, a method for intelligently adjusting the display brightness and power consumption is provided. This method dynamically adjusts the brightness of the display screen in different working environments and usage conditions, optimizes energy efficiency, extends device life, and improves user experience.
