In the method, the sample collection function (3) obtains the current screen luminous intensity value (current Nit value) (1) of the input value by adjusting the illumination from the current user through a control for adjusting the illumination, preferably a movement bar (seekbar), and obtains the sampling time value of the sample and the map mapping cached into a key-value form at the corresponding time point. The acquisition period is a sliding monitoring period of seekbar, namely, monitoring of starting and stopping of manual sliding of a user, so that when the user has manual sliding, a last value changes to form an array list of map mapping (last-time).
Then, the value acquired by the sample acquisition function (3) is sent to the file modification function (4) for judging curve modification. Xml, a time threshold of a sample map array list in the sample acquisition function (3) and a time period comparison threshold of each time of an array list of preset map mapping (Nit-time) configured by an engineer are obtained by the file modification function (4), the time threshold is compared with the array list of the preset map mapping, when the file modification function (4) judges that the array list of the preset map mapping is larger than the time threshold, a time bar for sliding of a user is fast, the sliding speed belongs to the speed of the habitual sliding seekbar of the user, and the array of the map mapping (Nit-time) needs to be adjusted to meet the habitual needs of the user. And when the Nit-time pair does not exist in the configuration file, distributing the collected Nit-time array pair to an array list of a map mapping (Nit-time) of the configuration file.
Then, the change of the array list of map mapping (Nit-time) triggers the interception callback of the database function to call the curve adjustment function (6) to perform curve adjustment.

The curve adjusting instruction is sent by a monotonicity detection function (7), the triggering condition is that a backlight adjusting curve function corresponding to an array list of map mapping (Nit-time) is a non-monotonicity function, the monotonicity detection function (7) calls the order of a matrix equation of a high-order least square method of an adjusting curve function (6) to adjust the backlight adjusting curve to be a monotonicity function, and the refitting of the backlight adjusting curve LSCT (8) is completed.
And then, before the acquired current Nit value, a backlight boundary comparator (15) is used for checking whether the current backlight value and the maximum value of the light emitting value of the Lcd exceed the config.xml boundary value of the system configuration file (only 8 bits are 255 and 16 bits are 4096), and if so, a proportion calculation function (14) is used for re-planning the Nit within the config.xml boundary value range. And calling a backlight value comparison function (13) according to the proportion calculation function (14) and the current Nit value adjusted by the backlight boundary comparator (15), wherein the backlight value comparison function (13) compares the adjusted Nit value with the current backlight value Lct _ cur to judge whether the intention of the user is to adjust the brightness up or down. An increasing loop function (11) is called if dimming is required and a decreasing loop function (12) is called if dimming is required.
Then, the backlight adjustment value Nit processed by the increasing cyclic function (11) or the decreasing cyclic function (12) is set as a parameter into a backlight adjustment curve (LSCF) (8), wherein the backlight adjustment curve (LSCF) (8) is a curve which is fitted according to configuration and a certain order by a least square method.
Through an array list of map mapping (Nit-time) formed by a backlight adjusting curve (LSCF) (8) strictly according to customer habits, a Timer (Timer) (10) is used for timing a time period of each time in the map mapping list so as to adjust an Nit value describing backlight intensity, and a backlight adjusting function (ABF) (9) is called to perform corresponding backlight adjustment at the moment, so that stable backlight adjustment is output, and user experience is improved.
