Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a backlight adjusting method according to an embodiment of the present disclosure. As shown in the figure, the method in the embodiment of the present application includes:
s101, the core layer receives a backlight adjusting instruction sent by the application layer, and the backlight adjusting instruction carries a first backlight brightness value of a target backlight channel in a plurality of backlight channels.
In a specific implementation, the first backlight brightness value is a backlight brightness value to which the target backlight channel needs to be adjusted, that is, a target backlight brightness value. The first backlight brightness value may be a specific brightness value (e.g., 120 nit), or may be a gear position value (e.g., 2 gear, 3 gear, etc.) of the backlight brightness, and an actual brightness value corresponding to each gear position may be set in advance. The backlight channel may be an LCD screen, an LED lamp, a meter dial, a meter pointer, etc. on a meter or an electronic device, among others. Since the plurality of backlight channels are operated in series within a time slice, the adjustment of the plurality of backlight channels does not interfere with each other.
S102, the core layer obtains backlight information of the target backlight channel, and the backlight information comprises a second backlight brightness value of the target backlight channel.
In a specific implementation, the second backlight brightness value is a current backlight brightness value of the target backlight channel, where the current backlight brightness value of each backlight channel may be stored in the core layer. During the first backlight adjustment, the current backlight brightness value of each backlight channel is preset by the application layer, and the preset brightness value is contained in the preset information base. Thereafter, the core layer updates the recorded backlight brightness value for each backlight channel after each backlight adjustment.
When each backlight channel comprises a plurality of brightness levels, the core layer may store the use condition of the current brightness level of the backlight channel by using data (denoted as M) of 1 or more bytes. For example, the backlight brightness of the LCD panel is divided into 8 steps, and the actual brightness values corresponding to the 1 st step to the 8 th step are preset to be 100nit, 115nit, 125nit, 130nit, 140nit, 145nit, 150nit and 152nit in sequence. Then, but not limited to, the use cases of the 8 th gear, the 7 th gear, … and the 1 st gear are sequentially represented by bit7, bit6, … and bit0 in M, where bit7, bit6, … and bit0 may take 0 or 1, for example, when M is 00001000, it represents that the backlight brightness of the current LCD screen is in the 4 th gear, and then it is determined that the current backlight brightness value is 130nit corresponding to the 4 th gear. If the backlight brightness of the LCD screen is adjusted to the 6 th gear subsequently, the core layer correspondingly updates M to 00100000.
And S103, the core layer receives a preset information base sent by the application layer, and the preset information base is configured by the application layer.
In a specific implementation, the preset information base includes preset backlight information configured by the application layer for each backlight channel. For example, the correspondence between each brightness level and the actual brightness value.
And S104, the core layer searches the backlight gradual change duration corresponding to the target backlight channel from the preset information base, wherein the preset information base comprises the corresponding relation between each backlight channel in the plurality of backlight channels and the backlight gradual change duration.
In a specific implementation, the backlight gradual change duration is a preset time taken for adjusting from the current backlight brightness value to the target backlight brightness value. The backlight gradual change time length can be any time length such as 1 second(s), 2s and the like. The backlight gradual change time lengths of different backlight channels can be the same or different. For example, the backlight gradual change duration corresponding to the LCD screen is 3s, and the backlight gradual change duration of the meter pointer is 1 s.
Optionally, different backlight gradual change durations may be set for different backlight modes of the same backlight channel, and different backlight gradual change durations may be set according to the current backlight brightness value and the target backlight brightness value of the target backlight channel. For example, for an LCD screen, when the adjusted shift span exceeds 3 (for example, from 1 st shift to 5 th shift), the backlight gradual change time length is set to 1s, and when the shift span does not exceed 3, the backlight gradual change time length is set to 0.5 s.
S105, the core layer determines a backlight brightness stepping value according to the first backlight brightness value, the second backlight brightness value and the backlight gradual change duration corresponding to the target backlight channel.
In a specific implementation, a difference between the first backlight luminance value and the second backlight luminance value may be calculated first, where the difference may be equal to a value obtained by subtracting the second backlight luminance value from the first backlight luminance value or may be equal to an absolute value of a difference between the first backlight luminance value and the second backlight luminance value, and then a backlight luminance step value is determined according to the difference and a backlight gradual change duration, where a quotient of the difference and the backlight gradual change duration may be used as the backlight luminance step value.
And S106, the core layer adjusts the backlight brightness value of the target backlight channel to the first backlight brightness value according to the backlight brightness stepping value.
In a specific implementation, the second backlight brightness value may be used as an initial brightness value for adjusting, and the backlight brightness may be adjusted step by step, which is equivalent to reaching the target backlight brightness value (the first backlight brightness value) through multiple adjustments. Therefore, the sum of the second backlight luminance value and the backlight luminance step value may be first calculated as the process luminance value in the adjustment process, wherein if the absolute value is taken for the difference between the first backlight luminance and the second backlight luminance in S105, it is first determined whether to adjust the backlight luminance up or down according to the magnitudes of the first backlight luminance value and the second backlight luminance value. If the process brightness value is adjusted to be lower, the sum of the second backlight brightness value and the backlight brightness stepping value is calculated to be the process brightness value, and if the process brightness value is adjusted to be higher, the backlight brightness stepping value is subtracted from the second backlight brightness value to be the process brightness value. Then, the backlight brightness is adjusted to a process brightness value, wherein the process brightness value can be converted into a corresponding pulse duty ratio, and then the pulse duty ratio of the current/voltage of a corresponding circuit in the target backlight channel is adjusted to the pulse duty ratio corresponding to the process brightness value by utilizing a Pulse Width Modulation (PWM) technology, so that the adjustment of the backlight brightness is realized; and then judging whether the brightness value of the process is equal to the first backlight brightness value or not, and if so, finishing the backlight adjustment. And if not, continuously adjusting the backlight brightness according to the process brightness value, the backlight brightness step value and the backlight gradual change duration, wherein the process brightness value can be taken as an initial brightness value, and the backlight brightness value of the target backlight channel is continuously adjusted according to the backlight brightness step value until the first backlight brightness value is reached.
It should be noted that, when the second backlight brightness value is not divided by the backlight gradual change duration, the last backlight brightness step value is taken as the sum of the quotient and the remainder of the adjustment starting point divided by the backlight gradual change duration. The whole process of adjustment will be described below by a specific example, and the "last backlight luminance step value" will be described.
For example: when the current backlight brightness value is 100nit, the target backlight brightness value to be adjusted is 135nit, and the backlight gradual change time length is 3s, the quotient obtained by dividing 35 by 3 by 135-100 is 10, and the remainder is 5. Wherein, the backlight brightness value can be adjusted from 100nit to 110nit according to the step value of 10; the backlight brightness value is adjusted from 110nit to 120nit by a step value of 10. At this time, the difference between 120nit and the target backlight brightness value 135nit is smaller than the step value 10 which is 2 times, so the sum of the step value replacement quotient and the remainder, i.e. 10+5 is 15, so that the backlight adjustment task of this time is ended in the next adjustment, and the replaced step value 15 is the last step value, and finally the backlight brightness value is adjusted from 120nit to 135nit according to the step value 15. Both 110nit and 120nit are process luminance values throughout the adjustment process.
Optionally, the core layer may also switch the backlight mode of each backlight channel, so that the backlight adjustment instruction may also carry first mode identification information of the backlight mode, and the first backlight mode corresponding to the first mode identification information is the backlight mode to which the target backlight channel needs to be switched, that is, the target backlight mode.
When the backlight adjustment instruction carries the mode identification information, correspondingly, the backlight information of the target backlight channel acquired by the core layer may further include second mode identification information, and a second backlight mode corresponding to the second mode identification information is a currently used backlight mode of the target backlight channel. Wherein the core layer can save the use state of each backlight mode of each backlight channel so as to determine the backlight mode currently used by any one backlight channel when needed. For example: the LCD screen has 8 backlight modes, mode 0, mode 1, … and mode 7, the use states of all backlight modes are represented by 1byte data, wherein, bit7, bit6, bit5, bit4, bit3, bit2, bit1 and bit0 represent the use states of mode 7, mode 6, … and mode 0 respectively, setting 0 represents exit, and setting 1 represents entry. The backlight color and the backlight brightness corresponding to each of the plurality of backlight modes of each backlight channel may be different.
Then, the core layer first searches the backlight colors corresponding to the first backlight mode and the second backlight mode from a preset information base. The preset information base comprises the corresponding relation between each backlight mode and the backlight color in the multiple backlight modes corresponding to each backlight channel. The backlight color of the target backlight channel is then switched from the first backlight color to the second backlight color, wherein the first backlight color may be turned off by reducing the forward duty cycle to zero using a PWM technique, and the forward duty cycle is momentarily adjusted to a duty cycle corresponding to the second backlight color. For example, an LCD screen needs to be momentarily switched from white to red, and then the red is turned on (momentary switching of the duty cycle in the core layer) while the white is turned off (momentarily reduced to 0% in the forward duty cycle).
For another example, when the LCD screen is currently in the first backlight mode, the backlight color is red, the backlight brightness is 3 steps, and the corresponding brightness value is 115 nit. And the backlight color of the LCD panel in the second backlight mode is blue, and the corresponding brightness value is 125nit when the backlight brightness is 3 th level. Therefore, if it is necessary to switch the backlight mode of the LCD panel to the second backlight mode, the backlight brightness is adjusted from 115nit to 125nit after the backlight color is switched from red to blue.
Optionally, the same backlight channel may be constrained by only one backlight mode at the same time, and the application layer is preset with usage priorities of multiple backlight modes of the same backlight channel, and the preset information base configured by the application layer includes a correspondence between each backlight mode of each backlight channel and the usage priority. Therefore, before switching the backlight color of the target backlight channel from the first backlight color to the second backlight color, the usage priority of the first backlight mode and the second backlight mode needs to be searched from the preset information base respectively. Then, when the first backlight mode has higher priority than the second backlight mode, the target backlight channel needs to be controlled to exit the first backlight mode.
Alternatively, while the core layer respectively represents the use states of the plurality of backlight modes using 1byte data (bit7, bit6, bit5, bit4, bit3, bit2, bit1, bit0), the use priority of each backlight mode may also be distinguished by high-bit data and low-bit data in the 1byte data.
For example: there are 8 backlight modes in total, mode 0, mode 1, …, mode 7. Among them, the 8 modes have the use priorities of mode 1, mode 4, mode 6, mode 0, mode 3, mode 2, mode 5, and mode 7 in order from high to low. The data of 1byte may sequentially represent the use states of mode 1, mode 4, mode 6, mode 0, mode 3, mode 2, mode 5, and mode 7 from the most significant bit (bit7) to the least significant bit (bit 0).

When the method in the embodiment of the present application is applied to devices with different backlight requirements and configurations, the corresponding configuration may be modified at the application layer.

Then, the core layer first searches the backlight colors corresponding to the first backlight mode and the second backlight mode from a preset information base. The preset information base comprises the corresponding relation between each backlight mode and the backlight color in the multiple backlight modes corresponding to each backlight channel. The backlight color of the target backlight channel is then switched from the first backlight color to the second backlight color, wherein the first backlight color may be turned off by reducing the forward duty cycle to zero using a PWM technique and the forward duty cycle is momentarily adjusted to a duty cycle corresponding to the second backlight color.

The first backlight brightness value may be a specific brightness value, or may also be a gear position value of the backlight brightness, and an actual brightness value corresponding to each gear position may be set in advance. Since the plurality of backlight channels are operated in series within a time slice, the adjustment of the plurality of backlight channels does not interfere with each other.

In a specific implementation, the backlight gradual change duration is a preset time taken for adjusting from the current backlight brightness value to the target backlight brightness value. The backlight gradual change time length can be any time length such as 1s and 2 s. The backlight gradual change time lengths of different backlight channels can be the same or different. For example, the backlight gradual change duration corresponding to the LCD screen is 3s, and the backlight gradual change duration of the meter pointer is 1 s.
The adjusting module 304 is configured to adjust the backlight brightness of the target backlight channel according to the backlight gradual change duration, the first backlight brightness value, and the second backlight brightness value corresponding to the target backlight channel.
In a specific implementation, a difference between the first backlight luminance value and the second backlight luminance value may be calculated first, where the difference may be equal to a value obtained by subtracting the second backlight luminance value from the first backlight luminance value or may be equal to an absolute value of a difference between the first backlight luminance value and the second backlight luminance value, and then a backlight luminance step value is determined according to the difference and a backlight gradual change duration, where a quotient of the difference and the backlight gradual change duration may be used as the backlight luminance step value.
In the embodiment of the present application, a method of gradually adjusting the backlight brightness by using the second backlight brightness value as the adjusted initial brightness value is taken, which is equivalent to achieving the target backlight brightness value (the first backlight brightness value) by adjusting for multiple times. Therefore, the sum of the second backlight brightness value and the backlight brightness step value may be calculated as the process brightness value in the adjustment process, wherein if the absolute value of the difference between the first backlight brightness and the second backlight brightness is obtained in the process of obtaining the backlight brightness step value, it is first determined whether to adjust the backlight brightness higher or lower according to the magnitudes of the first backlight brightness value and the second backlight brightness value. If the process brightness value is adjusted to be lower, the sum of the second backlight brightness value and the backlight brightness stepping value is calculated to be the process brightness value, and if the process brightness value is adjusted to be higher, the backlight brightness stepping value is subtracted from the second backlight brightness value to be the process brightness value. Then, adjusting the backlight brightness to a process brightness value, wherein the process brightness value can be converted into a corresponding pulse duty ratio, and then the pulse duty ratio of the current/voltage of a corresponding circuit in the target backlight channel is adjusted to the pulse duty ratio corresponding to the process brightness value by utilizing a PWM (pulse width modulation) technology, so that the adjustment of the backlight brightness is realized; and then judging whether the brightness value of the process is equal to the first backlight brightness value or not, and if so, finishing the backlight adjustment.

Wherein, the use state of each backlight mode in each backlight channel can be saved in the core layer device, so as to determine the backlight mode currently used by any one backlight channel when needed. For example: the LCD screen has 8 backlight modes, mode 0, mode 1, … and mode 7, the use states of all backlight modes are represented by 1byte data, wherein, bit7, bit6, bit5, bit4, bit3, bit2, bit1 and bit0 represent the use states of mode 7, mode 6, … and mode 0 respectively, setting 0 represents exit, and setting 1 represents entry. The backlight color and backlight brightness for each backlight mode of each backlight channel may be different.
Then, the searching module 303 is used to search the backlight colors corresponding to the first backlight mode and the second backlight mode from the preset information base. The preset information base comprises the corresponding relation between each backlight mode and the backlight color in the multiple backlight modes corresponding to each backlight channel.

For example, an LCD screen needs to be momentarily switched from white to red, and then the red is turned on (momentary switching of the duty cycle in the core layer) while the white is turned off (momentarily reduced to 0% in the forward duty cycle).
Optionally, the same backlight channel may be constrained only by one backlight mode at the same time, and the application layer is preset with usage priorities of multiple backlight modes of the same backlight channel, and the preset information base configured by the application layer includes a correspondence between each of the multiple backlight modes of each backlight channel and the usage priority. Therefore, before switching the backlight color of the target backlight channel from the first backlight color to the second backlight color, the searching module 303 is further configured to search the preset information base for the usage priority of the first backlight mode and the second backlight mode, respectively. The adjusting module 304 is further configured to control the target backlight channel to exit the first backlight mode when the first backlight mode has a higher priority than the second backlight mode.
