Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic diagram of a possible application scenario provided in the embodiment of the present invention. The application scenario includes an electronic device with a display screen, where the electronic device with the display screen may be a mobile phone, a tablet, or other electronic devices with a display screen, and is not limited herein. The Operating System of the electronic device with the display screen may be an Android System (Android), an apple System (iOS), or other systems, which is not limited herein. Fig. 1 illustrates a mobile phone 100, where the mobile phone 100 is an android system. The backlight brightness is the brightness of the display screen of the mobile phone, and generally, the mobile phone 100 has a function of adjusting the backlight brightness, wherein the function of adjusting the backlight brightness is divided into automatic backlight brightness adjustment and manual backlight brightness adjustment. The manual adjustment of the backlight brightness is that the user slides the mobile phone brightness bar according to the current environment of the user, so as to adjust the backlight brightness of the mobile phone 100, but in this case, the user needs to manually adjust the backlight brightness constantly along with the change of the environment where the user is located, so that the user needs to adjust the backlight brightness according to the environment where the user is located, which is too frequent in operation, and the experience of the user is reduced. The automatic backlight brightness adjustment is that the backlight brightness controller in the mobile phone 100 correspondingly controls the backlight brightness in the mobile phone 100 by changing the current according to the brightness of the environment where the mobile phone is located, so that the experience of the user can be improved, and therefore, the user is more and more selected.
Fig. 2 is a schematic diagram illustrating a relationship between a backlight luminance bar and a backlight value of a mobile phone according to an embodiment of the present invention. As can be seen from fig. 2, the backlight luminance bars of the mobile phone are pulled to different positions corresponding to different backlight values. In a possible case, since the eyes of the user are sensitive to the change of the light source in a low-brightness environment and are not easy to perceive the change of the light source in a brighter environment, the change of the backlight value is very gentle in a low-brightness interval, and the change of the backlight value in a large range can occur in a high-brightness interval. In the process of automatically adjusting the backlight brightness of the mobile phone 100 in a dark environment, although the change of the backlight brightness is slow, the current controlled by the backlight brightness controller in the mobile phone 100 cannot be further refined corresponding to the slight change of the backlight brightness bar, and in the process of the change of the backlight brightness, there may be fluctuation of the current, so that the user still feels that the brightness of the display screen is obviously changed in the process of automatically adjusting the brightness of the display screen in the dark environment, that is, the display screen flickers, thereby causing discomfort of eyes when the user uses the mobile phone 100 in the dark environment, affecting the use of the user, and reducing the use feeling of the user.
In view of this, the method for adjusting brightness provided in the embodiments of the present invention can solve the problem that the display screen flickers in a dark environment by increasing the repetition times of the backlight value in the low-brightness interval.
In the embodiment of the present invention, the electronic device with a display screen may be a mobile phone, a tablet, or other electronic devices, which are not limited herein.
As shown in fig. 3, a flowchart of a method for adjusting backlight brightness according to an embodiment of the present invention is provided, where the method includes the following steps:
A first node in the mobile phone is started, the first node sends indication information to a second node, wherein the indication information is used for indicating the second node to acquire a first backlight parameter according to the flickering condition, and the first backlight parameter comprises a first backlight interval, a first repetition rate and a first jump rate. For example, if the mobile phone has a screen flickering in the interval [0,400], then [0,400] is determined as the first backlight interval, where the sequence of backlight values in the first backlight interval is 0,1,2, 3. The initial value of the first backlight interval is 0, the maximum value of the first backlight interval is 400, the repetition rate of the first backlight interval is 1 because the backlight value of the first backlight interval is changed from 1 to 2, and the sequence is from 2 to 3, and the first jump rate is 1 because the jump of the first backlight interval is changed from 1 to 2.
In the embodiment of the present invention, the second backlight parameter includes a second backlight interval, a second repetition rate, and a second jump rate. For example, if the first backlight interval is [0,400], the first backlight interval includes 400 backlight values, the minimum value of the first backlight interval is 0, the maximum value of the first backlight interval is 400, and the difference between the maximum value and the minimum value of the first backlight interval is 400, which may result in a large variation range of the backlight brightness, and may cause a situation that the display screen flickers.
Specifically, in the first backlight interval [0,400], the display screen may flicker due to the large variation difference of the backlight values, and there are a total of 400 backlight values in the first backlight interval [0,400], where the order of the backlight values in the first backlight interval is 0,1,2, 3. In order to avoid the flicker of the display screen, the change difference of the backlight value can be reduced by increasing the repetition rate of the backlight interval. Since the backlight values of the first backlight section are not repeated, the repetition rate of the first backlight section is 1, if the repetition rate of the second backlight section is 2, the repetition frequency of each backlight value of the second backlight section is 2, and since the total number of the backlight values is unchanged, the second backlight section is still 400 backlight values, the sequence of the adjusted backlight values of the second backlight section is 0,0,1,1,2, 2. The adjusted first backlight interval is referred to as a second backlight interval. The second backlight interval is [0,200], the initial value of the second backlight value is 0, the maximum value of the second backlight value is 200, the backlight value is changed from 0 to 1, the second jump rate of the second backlight interval is 1, and therefore the second jump rate of the second backlight interval is equal to the first jump rate of the first backlight interval. The variation difference of the first backlight interval is 400, and the variation difference of the second backlight interval is 200, so that the variation difference of the second backlight interval can be reduced by increasing the repetition rate of the second backlight interval, and the flicker feeling of the display screen is reduced. Also, since the order of the second backlight sections is 0,0,1,1,2, 2.
And step 303, the second node adjusts the backlight brightness according to the second backlight parameter.
In the embodiment of the present invention, as shown in fig. 4, a schematic diagram of adjusting a backlight luminance bar according to the embodiment of the present invention is provided. For example, if the first backlight interval is [0,400], wherein the minimum value of the first backlight interval is 0, the maximum value is 400, and the total number of backlight values is 400. Determining a second backlight interval according to the first backlight interval and a second repetition rate, if the second repetition rate is 2, the second backlight interval is [0,200], wherein the minimum value of the second backlight interval is 0, the maximum value is 200, and the total number of backlight values is still 400, such that although the total number of backlight values is not changed, the maximum value of the second backlight interval is 200, which is much smaller than the maximum value of the first backlight interval 400, and the difference between the maximum value of the second backlight interval and the minimum value of the second backlight interval is 200, and the difference between the maximum value of the first backlight interval and the minimum value of the first backlight interval is 400, since the larger the difference between the maximum value and the minimum value of the backlight interval is, the larger the corresponding variation of the backlight brightness is, and therefore, the difference between the maximum value of the second backlight interval and the minimum value of the second backlight interval is reduced on the premise of maintaining the total number of backlight values in the second backlight interval, therefore, the backlight brightness variation corresponding to the second backlight interval can be reduced, so that the backlight brightness variation in the second backlight interval is slower, and the flicker feeling of the display screen in the second backlight interval is reduced.
It can be seen from steps 301 to 303 that, through the second repetition rate, the repetition frequency of each backlight value in the second backlight interval can be increased, so that on the premise of keeping the total number of the backlight values unchanged, the difference between the maximum value of the second backlight interval and the minimum value of the second backlight interval is reduced, thereby reducing the backlight brightness variation corresponding to the second backlight interval, and realizing that the backlight brightness variation in the second backlight interval is slower, thereby realizing backlight brightness adjustment, reducing the flicker of the display screen in the second backlight interval, and improving the experience of the user.
The scheme of fig. 3 above can be implemented by relevant codes, which are described below and will not be described herein again.
After the first backlight interval is adjusted to the second backlight interval, the backlight brightness change in the second backlight interval can be realized slowly by reducing the second backlight interval, but the maximum value of the second backlight interval is reduced due to the reduction of the second backlight interval, the maximum value cannot be linked with the subsequent backlight value without difference, the difference between the maximum value of the second backlight interval and the subsequent backlight value is greatly different, the brightness change is uneven, and the problem of display screen flicker is caused. The problem of reducing the flicker of the display screen by the fourth backlight section is described below.
For example, if the total backlight interval is [0, 4095], the first backlight interval is [0,400], the first repetition rate is 1, the first jump rate is 1, and when the second repetition rate is 2 and the second jump rate is 1, the second backlight interval is [0,200], although the second backlight interval is obtained by increasing the number of repetitions of each backlight value in the first backlight interval, so that the change in the backlight luminance in the display screen is more gradual, thereby reducing the flicker sensation of the display screen, the maximum value of the first backlight interval is 400, and the sequence of the total backlight intervals is 0,1,2,3,4,5, …, 4092,4093,4094,4095 according to the total backlight interval of [0, 4095 ]. The remaining backlight interval should be [400, 4095], and the second backlight interval, although also 400 backlight values, has a maximum value of 200, and if there is no transition interval in between and the remaining backlight intervals are directly connected, the order of the remaining backlight intervals is 201,401,402, …, 4095. If the backlight value is from 200 to 400, the display screen still has a flicker feeling due to the large variation of the backlight value. Therefore, in order to reduce the flicker feeling of the display screen, after the second backlight interval, a transition interval for connecting the second backlight interval and the remaining backlight interval needs to be added. The transition section corresponding to the second backlight section is referred to as a fourth backlight section. The first backlight interval corresponds to a third backlight interval, wherein the maximum value of the third backlight interval is the same as that of the fourth backlight interval.
The following describes that the fourth backlight interval can better connect the second backlight interval with the remaining backlight interval by determining the fourth jump rate of the fourth backlight interval, so as to reduce the flicker feeling of the display screen.
Fig. 5 is a diagram illustrating a relationship among a first backlight interval, a second backlight interval, a third backlight interval and a fourth backlight interval according to an embodiment of the present invention. The first backlight parameters further comprise a third backlight interval, a third repetition rate and a third jump rate. The second backlight parameters further include a fourth backlight interval, a fourth repetition rate, and a fourth jump rate. The maximum value of the first backlight interval is the minimum value of the third backlight interval, that is, the first backlight interval is connected with the third backlight interval. The maximum value of the second backlight interval is the minimum value of the fourth backlight interval, that is, the second backlight interval is connected with the fourth backlight interval.
For example, if the first backlight interval is [0,400], the number of backlight values is 400, and the second repetition rate is 2, the second backlight interval is [0,200], wherein the maximum value of the second backlight interval is 200, and the sequence of the backlight values of the second backlight interval is 0,0,1,1,2, 2. If the maximum value of the third backlight interval is 600, the maximum value of the third backlight interval is the same as the maximum value of the fourth backlight interval, so the maximum value of the fourth backlight interval is 600, and the minimum value of the third backlight interval is the maximum value of the first backlight interval, so the third backlight interval is [401, 600], since the third backlight interval and the fourth backlight interval are not the interval where the display screen flickers but belong to the high-luminance interval, and the change of luminance is not easily found in the high-luminance environment according to human eyes, the third jump rate of the third backlight interval is 2, the third repetition rate is 1, the sequence of the backlight values of the third backlight interval is 400,402,404, 600, and the total number of the backlight values is 200. Since the total number of backlight values of the fourth backlight section is the same as that of the third backlight section, the fourth backlight section is [200,600], the fourth repetition rate of the fourth backlight section is 1, and in order to maintain the total number of backlight values to be 200, the fourth jump rate of the fourth backlight section may be determined to be 4. The second backlight interval and the fourth backlight interval are combined, so that the second backlight interval and the fourth backlight interval can be better connected with the residual backlight interval [600,4095], and the problem of display screen flicker caused by overlarge difference of adjacent backlight values is avoided. It will be appreciated that 600,4095 belongs to a high brightness interval in which no flicker of the display screen occurs.
By adjusting the first backlight interval to the second backlight interval and the third backlight interval to the fourth backlight interval, the flicker feeling of the display screen can be reduced, and the experience feeling of a user can be improved.
As shown in fig. 6, a graph of the luminance of the backlight according to the embodiment of the present invention is provided. As can be seen from fig. 6, the repetition number of each backlight value in the second backlight section is increased by the second repetition rate, and the difference between each backlight value in the fourth backlight section is increased by the fourth transition rate, so that the luminance change corresponding to the second backlight section is relatively gentle with respect to the luminance change corresponding to the first backlight section, and the problem of flicker of the display screen is reduced. The brightness change corresponding to the fourth backlight interval is relatively large compared with the brightness change corresponding to the third backlight interval, and because the difference of brightness is not easy to see by a user in the high-brightness interval, on the premise that flicker of the display screen does not occur, the fourth backlight interval is used as a transition interval, so that the second backlight interval and the subsequent backlight interval can be better connected, and the flicker condition can not occur in the whole backlight interval.
Based on the foregoing, a specific implementation manner provided by the embodiment of the present invention is given below with reference to a specific example.
This is achieved in that the second backlight section may have a plurality of repetition rates. For example, if the first backlight interval is [0,400], the number of backlight values is 400, and the order of the backlight values in the first backlight interval is 0,1,2, 3. The first repetition rate of the first backlight interval is 1, the first jump rate is 1, if the first backlight interval [0,400] is divided into two intervals, namely interval 1 and interval 2, if interval 1 is [0,200], interval 2 is [201,400], the repetition rate corresponding to interval 1 is set to 1, adjusted interval 1 is [0,200], the repetition rate corresponding to interval 2 is set to 2, the number of repetitions of the backlight value of interval 2 is 2, adjusted interval 2 is [201,300], and a second backlight interval can be obtained by combining adjusted interval 1 and adjusted interval 2, wherein the second backlight interval is [0, 300], and the second backlight interval has two repetition rates, namely repetition rate 1 used in interval 1 and repetition rate 2 used in interval 2. The variation difference of the first backlight section is 400, the second jump rate of the second backlight section is 1, and the variation difference of the second backlight section is 300, so that the variation difference of the second backlight section can be reduced by setting a plurality of repetition rates, and the flicker feeling of the display screen can be reduced.
The relevant codes are as follows:
based on the same technical concept, the embodiment of the invention also provides a device for adjusting the backlight brightness, and the control device can execute the method in the method embodiment. Referring to fig. 7, the structure of the apparatus provided by the embodiment of the present invention may be seen, where the apparatus 700 includes: the obtaining unit 701 is configured to obtain a first backlight parameter, where the first backlight parameter includes a first backlight interval, a first repetition rate, and a first jump rate.
