Detailed Description
As described above, in the prior art, a large and bulky array list has high difficulty in maintenance, and the adjustment accuracy is limited, so that both the adjustment accuracy and the maintenance convenience cannot be achieved.
In order to solve the above problem, in the embodiment of the present invention, the backlight brightness adjustment configuration information includes a linear mapping relationship between the brightness adjustment value and the screen brightness, and the linear mapping relationship between the brightness adjustment value and the screen brightness is obtained at least according to the brightness adjustment value range and the maximum screen brightness and the minimum screen brightness indicated by the screen brightness range of the display screen, and when the backlight brightness adjustment configuration information is obtained, the maximum screen brightness and the minimum screen brightness of the display screen and the brightness adjustment value range are taken into consideration, so that the accuracy of the linear mapping relationship between the brightness adjustment value and the screen brightness can be improved, the adjustment accuracy of the target screen brightness can be further improved, and the configuration convenience can be also considered.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a method for adjusting backlight brightness of a display screen in an embodiment of the present invention is shown, which may specifically include the following steps:
in step S11, a target brightness adjustment value is acquired.
In particular implementations, the target brightness adjustment value may be obtained in a variety of ways.
In an embodiment of the present invention, the target brightness adjustment value is obtained according to the brightness adjustment information input by the user. Specifically, a brightness adjustment bar for brightness adjustment may be provided, and the user may adjust the brightness by dragging the brightness adjustment bar, where the brightness adjustment information is a dragging position of the brightness adjustment bar. And determining a target brightness adjusting value according to the dragging position of the brightness adjusting strip. It is to be understood that an input box for inputting the target brightness adjustment value may be also provided, and the user may input the target brightness adjustment value through the input box.
In another embodiment of the present invention, in a scene where the brightness of the display screen is configured to be automatically adjusted, the target brightness adjustment value may be obtained according to the ambient brightness. The corresponding mapping relationship between the ambient brightness and the target brightness adjustment value can be preset.
In another embodiment of the present invention, in order to meet personalized requirements of different users, a target brightness adjustment value may be obtained according to the ambient brightness of the environment where the user is located and brightness adjustment information input by the user. Specifically, the user may adjust the brightness by dragging the brightness adjustment bar, and determine the target brightness adjustment value according to the dragged position of the brightness adjustment bar in combination with the ambient brightness of the environment where the brightness adjustment bar is located.
For example, the intermediate brightness adjustment value is determined according to the ambient brightness of the environment, and the intermediate brightness adjustment value is adjusted according to the brightness adjustment information input by the user to obtain the target brightness adjustment value, where the target brightness adjustment value may be greater than the intermediate brightness adjustment value, may also be smaller than the intermediate brightness adjustment value, and may also be equal to the intermediate brightness adjustment value.
In step S12, backlight brightness adjustment configuration information is acquired.
In a specific implementation, the backlight brightness adjustment configuration information may include a linear mapping relationship between the brightness adjustment value and the screen brightness.
In the embodiment of the present invention, a screen brightness range of the display screen may be obtained, and the screen brightness range of the display screen may include a maximum screen brightness and a minimum screen brightness. And obtaining backlight brightness adjustment configuration information at least according to the brightness adjustment range, the maximum screen brightness and the minimum screen brightness configuration.
In an embodiment of the present invention, the backlight brightness adjustment configuration information may be configured in the following manner:
and acquiring a maximum brightness adjusting value and a minimum brightness adjusting value in the brightness adjusting value range. And acquiring the maximum screen brightness and the minimum screen brightness of the screen brightness range. And calculating the conversion rate between the screen brightness and the brightness adjusting value according to the maximum screen brightness, the minimum screen brightness, the maximum brightness adjusting value and the minimum brightness adjusting value. And configuring to obtain backlight brightness adjustment configuration information according to the minimum screen brightness, the conversion rate and the minimum brightness adjustment value.
The conversion rate between the screen brightness and the brightness adjusting value is the ratio of the difference between the maximum screen brightness and the minimum screen brightness and the difference between the maximum brightness adjusting value and the minimum brightness adjusting value.
In practical application, when configuring brightness adjustment information, a user only needs to input maximum screen brightness, minimum screen brightness, a maximum brightness adjustment value and a minimum brightness adjustment value, and the configuration is simple and convenient.
And step S13, calculating the target screen brightness according to the backlight brightness adjustment configuration information and the target brightness adjustment value.
In a specific implementation, the backlight brightness adjustment configuration information includes a brightness adjustment value and a linear mapping relationship between screen brightness of the display screen, so that the target screen brightness can be calculated according to the target brightness adjustment value.
In the embodiment of the present invention, the target screen brightness may be calculated by using the following formula (1):
where y is the target screen brightness, ymaxIs the maximum screen brightness, yminIs the minimum screen brightness, x is the brightness adjustment value, xmaxFor maximum brightness adjustment value, xminIn order to be the minimum brightness adjustment value,
is the conversion rate.
It is found through research that, in the prior art, when backlight modulation is performed in an array list manner, it is required to make the backlight modulation range of the application layer of the operating system consistent with the brightness modulation range of the hardware, for example, the backlight modulation range of the application layer is [0, 255], and the brightness modulation range of the hardware is [0, 255 ]. However, the brightness adjustment range supported by the hardware is not limited to [0, 255], which is usually greater than 255, and if the adjustment precision of the hardware is fully utilized, the brightness adjustment range supported by the hardware needs to be increased, and the backlight adjustment range of the application layer needs to be correspondingly increased, which results in a huge array list, tedious configuration and high difficulty in maintenance, and thus the brightness adjustment precision of the hardware, the full use of the hardware brightness adjustment range, the convenience of configuration and maintenance, and the like cannot be considered.
Research shows that in the prior art, the target screen brightness is determined according to the percentage of the target brightness adjustment value and the maximum brightness adjustment value and by combining the brightness adjustment range of hardware. Since the percentage of the target brightness adjustment value to the maximum brightness adjustment value is 0 to 100% (or 0 to 1), only the mapping between the target brightness adjustment value 0-255 and the screen brightness 0-Y, where Y is the set screen brightness, can be achieved. When the brightness adjustment range of the hardware is not started from 0, but started from the brightness Y ', when the target screen brightness is determined by adopting the scheme of the percentage of the target brightness adjustment value and the maximum brightness adjustment value, the screen brightness is also adjusted to be started from 0, the actual display screen brightness is started from Y ', and when the calculated target screen brightness is between 0 and Y ', the brightness adjustment is failed.
In order to solve the above problem, in the embodiment of the present invention, the maximum screen brightness, the minimum screen brightness, the maximum brightness adjustment value, and the minimum brightness adjustment value may all be configured according to actual requirements, the minimum screen brightness may be 0, and the minimum screen brightness may not be 0, that is, the screen brightness range may be configured as any range according to requirements. It can be understood that the minimum brightness adjustment value may be 0 or not, and the value of the minimum brightness adjustment value may be configured according to the requirement of the actual application scene. The conversion rate between the screen brightness and the brightness adjusting value is the ratio of the difference value between the maximum screen brightness and the minimum screen brightness and the difference value between the maximum brightness adjusting value and the minimum brightness adjusting value, so that the mapping between the brightness adjusting value range and any screen brightness range can be realized.
In an embodiment of the present invention, a value of the maximum screen brightness may be the same as or different from a value of the maximum brightness adjustment value. For example, the brightness adjustment value range may be [0, 255], and the screen brightness adjustment range may be [0, 1023 ]. For another example, the brightness adjustment value range may be [0, 255], and the screen brightness adjustment range may be [10, 888 ]. The smoothness and the precision of the brightness adjustment value mapped to the screen brightness are improved, and the precision of the brightness adjustment of the display screen is further improved. In addition, the minimum screen brightness of the display screen is considered when the target screen brightness is calculated, the calculated target screen brightness is prevented from exceeding the screen brightness range, and the brightness adjustment precision can be further improved. Since the screen brightness range can be freely configured without the limitation from 0, the configuration freedom of the backlight brightness adjustment range can be improved.
In a specific implementation, when the calculated target screen brightness is not an integer, a rounding operation may be performed, and the rounded brightness may be used as the target screen brightness. Wherein, the rounding can be performed downwards or upwards.
And step S14, controlling the backlight brightness of the display screen to be adjusted to the target screen brightness according to the target screen brightness.
In specific implementation, after the target screen brightness is obtained through calculation, the backlight brightness of the display screen is controlled to be adjusted to the target screen brightness according to the target screen brightness.
Specifically, the duty ratio, frequency, and the like of Pulse Width Modulation (PWM) may be determined according to the target screen brightness, and the backlight brightness of the display screen may be controlled to be adjusted to the target screen brightness according to the duty ratio and the frequency.
As can be seen from the above, the backlight brightness adjustment configuration information includes a linear mapping relationship between the brightness adjustment value and the screen brightness, and the linear mapping relationship between the brightness adjustment value and the screen brightness is obtained at least according to the brightness adjustment value range and the maximum screen brightness and the minimum screen brightness indicated by the screen brightness range of the display screen, when the backlight brightness adjustment configuration information is obtained, the maximum screen brightness and the minimum screen brightness of the display screen and the brightness adjustment value range are taken into consideration comprehensively, so that the accuracy of the linear mapping relationship between the brightness adjustment value and the screen brightness can be improved, the adjustment accuracy of the target screen brightness can be improved, and the convenience of configuration can be also taken into consideration.
In addition, by adopting the backlight brightness adjusting method of the display screen provided by the invention, the backlight brightness adjusting configuration information can be configured according to the brightness adjusting value range and the screen brightness range of the display screen, the configuration mode is simple and convenient, the configuration efficiency can be improved, and the improvement of the production efficiency can be expected.
