A brief description of some of the terms referred to in this application is provided below, as follows:
backlight: backlight is a measure of the brightness of a screen display.
LUX: lux, the ambient light value, is a measure of the amount of light received by a light sensor. lux, the legal notation lx, is the unit of illumination (luminance). When the luminous flux obtained for an object uniformly irradiated with light is 1 lumen over an area of 1 square meter, the illuminance is 1 lux.
nit: which is used to measure the display brightness of the screen itself. Nit is the unit of luminance, 1nit =1cd/m. The brightness is a physical quantity of the intensity of light emission (reflection) on the surface of a light-emitting body (reflector). The ratio of the intensity of light in a direction in which a human eye observes a light source to the area of the light source "seen" by the human eye is defined as the luminance of the light source unit, i.e., the luminous intensity per unit of projected area. Luminance is given in candelas per square meter (cd/m) 2 ) Luminance is the human perception of the intensity of light. Brightness refers to the degree of shading of an object, defined as luminous intensity per unit area, in nit (nit), 1nit =1 candela/square meter, lumen (LM) is the unit of luminous flux.
HBM: the High Brightness Model, highlight mode, is much brighter than the screen Brightness for maximum backlight level display.
With the widespread use of electronic devices such as mobile phones, the background brightness display of the screen is also paid more attention by many people, and even becomes a standard for measuring the quality of one mobile phone. Different mobile phones and different screens have different displayable ranges of backlight, for example, some screens support a backlight level of 2047, while some screens support a backlight level of 4095, and even support a ten-thousand-level dimming technology, where the larger the backlight level is, the higher the screen background brightness is, and conversely, the smaller the backlight level is, the lower the screen background brightness is.

A minimum backlight level control progress bar and a maximum backlight level control progress bar are designed. Fig. 2 is a schematic diagram of a lowest backlight level control progress bar and a highest backlight level control progress bar in the embodiment of the present application. Fig. 3 is a schematic diagram illustrating the adjustment operation performed by the user on the minimum backlight level control progress bar according to the embodiment of the present application.
102. And adjusting the screen backlight brightness according to the current lowest backlight grade and/or the current highest backlight grade.
Optionally, the adjusting the screen backlight brightness according to the current lowest backlight level and/or the current highest backlight level may include:
obtaining the current lowest screen backlight brightness according to the current lowest backlight grade, the default lowest backlight grade and the default lowest screen backlight brightness; and/or obtaining the current highest screen backlight brightness according to the current highest backlight grade, the default highest backlight grade and the default highest screen backlight brightness; adjusting a configuration curve according to the current lowest backlight grade and the current lowest screen backlight brightness, and/or the current highest backlight grade and the current highest screen backlight brightness; and adjusting the backlight brightness of the screen according to the adjusted configuration curve.
Optionally, the obtaining the current lowest screen backlight brightness according to the current lowest backlight level, the default lowest backlight level, and the default lowest screen backlight brightness may include:
obtaining the current lowest screen backlight brightness according to a first formula;
the first formula is: l is min Default /x min Default ＝L min is currently /x min is currently ；
Wherein L is min Default Is the default minimum backlight level, x min Default Is the default minimum screen backlight brightness, L min is currently Is the current lowest backlight level, x min is currently Is the current lowest screen backlight brightness;
obtaining the current highest screen backlight brightness according to the current highest backlight level, the default highest backlight level, and the default highest screen backlight brightness may include:
obtaining the current highest screen backlight brightness according to a second formula;
the second formula is: l is max default /x max default ＝L max is currently /x max is currently ；
Wherein L is min Default Is the default highest backlight level, x min Default Is the default maximum screen backlight brightness, L max is currently Is the current highest backlight level, x max is currently Is the current highest screen backlight brightness.
Optionally, the screen backlight brightness corresponding to the current lowest backlight level is less than or greater than the screen backlight brightness corresponding to the default lowest backlight level; and the screen backlight brightness corresponding to the current highest backlight level is smaller than or larger than the screen backlight brightness corresponding to the default highest backlight level. That is, it can be understood that the current lowest backlight level adjusted by the user is different from the default lowest backlight level, and the current highest backlight level adjusted by the user is different from the default highest backlight level.
Optionally, an adjustable range of a lowest backlight level corresponding to the lowest backlight level control bar is [ a first lowest backlight level, a second lowest backlight level ], a screen backlight luminance corresponding to the first lowest backlight level is less than a screen backlight luminance corresponding to the default lowest backlight level, and a screen backlight luminance corresponding to the second lowest backlight level is greater than the screen backlight luminance corresponding to the default lowest backlight level;
the adjustable range of the highest backlight level corresponding to the highest backlight level control bar is [ a first highest backlight level, a second highest backlight level ], the screen backlight brightness corresponding to the first highest backlight level is smaller than the screen backlight brightness corresponding to the default highest backlight level, and the screen backlight brightness corresponding to the second highest backlight level is larger than the screen backlight brightness corresponding to the default highest backlight level.
For example, regarding the setting of the lowest backlight level control bar, in the prior art, generally, the lowest backlight level is designed to be about 8, the corresponding lowest screen backlight brightness is about 10nit, 8 can be regarded as the default lowest backlight level, and actually the lowest screen brightness level can reach 0, and for some users, the screen brightness 10nit corresponding to the default lowest backlight level 8 is dark enough, so the lowest backlight level can be set to be high, and thus, for example, the lowest backlight level adjustable range can be set to [0, 16]. The selection of the lowest backlight level may be {0,1,2,3,4,5,6,7,8,9, 10, 11, 12, 13, 14, 15, 16}; or {0,2,4,6,8, 10, 12, 14, 16}; the number of the electrodes may be {0,4,8, 12, 16}, or the like, and is not particularly limited.
However, since the lowest backlight level is set to 0, which means that the entire black is completely invisible, it is not recommended to set the lowest backlight level to 0 in the present application. For example, the lowest backlight level adjustable range may be set to [1, 15], then the selection of the lowest backlight level may be {1,2,3,4,5,6,7,8,9, 10, 11, 12, 13, 14, 15}; may be {1,3,5,7,9, 11, 13, 15}, may also be {1,5,9, 13}, etc., and is not particularly limited; for example, the lowest backlight level adjustable range may also be set to [2, 14], and then, the selection of the lowest backlight level may be {2,3,4,5,6,7,8,9, 10, 11, 12, 13, 14}, or {2,4,6,8, 10, 12, 14}; the number of the optical fibers may be {4,8, 12}, and the like, and is not particularly limited.
Illustratively, regarding the setting of the highest backlight level control bar, the highest screen backlight brightness varies according to the screen type and the hardware support, and the default highest backlight level is, for example, 2047 standard, which corresponds to 460 (nit) of the highest screen backlight brightness. The maximum backlight level range varies greatly, for example, the maximum backlight level (maxBrightness) adjustable range is [1747, 2347], a gradient can be set at 100 units, and three steps can be performed left and right as the minimum backlight brightness, and then the maximum backlight level can be selected from {1747, 1847, 1947, 2047, 2147, 2247, 2347}; or a gradient in units of 50, then the choice of the highest backlight level may be {1747, 1797, 1847, 1897, 1947, 1997, 2047, 2097, 2147, 2197, 2247, 2297, 2347}; the gradient may be in other units, and is not particularly limited.
Optionally, the default lowest backlight level is a middle level of the first lowest backlight level and the second lowest backlight level; the default highest backlight level is a middle level of the first highest backlight level and the second highest backlight level.
It is to be understood that the default lowest backlight level and the default highest backlight level are the default lowest backlight level and the default highest backlight level in the prior art, because in the prior art, the default lowest backlight level is the lowest backlight level and cannot be adjusted downward any more, and the default highest backlight level is the highest backlight level and cannot be adjusted upward any more. In this implementation manner, the default lowest backlight level is a middle level between the first lowest backlight level and the second lowest backlight level, that is, the center level, and for the user, the selection level of the lowest backlight level to be turned up is the same as the selection level of the lowest backlight level to be turned down, so that the user's requirements are considered fully and fairly; then, for some users, in some scenes, the screen backlight brightness corresponding to the default lowest backlight level is too high, and can be adjusted to be low again; for some users, in some scenarios, the screen backlight brightness corresponding to the default lowest backlight brightness level is perceived as too low and may be further adjusted to a higher level. The default highest backlight level is the middle level of the first highest backlight level and the second highest backlight level, namely the center level, for a user, the selection level of the highest backlight level which is adjusted to be higher is the same as the selection level of the highest backlight level which is adjusted to be higher, and the requirements of the user are considered fully and fairly; for some users, in some scenes, the screen backlight brightness corresponding to the default highest backlight level is too high, and the screen backlight brightness can be adjusted to be low; for some users, in some scenarios, the screen backlight brightness corresponding to the default highest backlight brightness level is perceived as too low and may be further adjusted to a higher level.
Illustratively, assuming that the default lowest backlight level is 8, the lowest backlight level adjustable range corresponding to the lowest backlight level control bar is {2,4,6,8, 10, 12, 14}, and 8 belongs to the middle level of the lowest backlight level adjustable range. Assuming the default highest backlight level is 2047, the highest backlight level adjustable range for the highest backlight level control bar is {1747, 1847, 1947, 2047, 2147, 2247, 2347}, and 2047 belongs to the middle level of the highest backlight level adjustable range.
Optionally, at least one lowest backlight level exists between the first lowest backlight level and the default lowest backlight level, and at least one lowest backlight level exists between the default lowest backlight level and the second lowest backlight level;
there is at least one highest backlight level between the first highest backlight level and the default highest backlight level, and there is at least one highest backlight level between the default highest backlight level and the second highest backlight level.
For example, assuming that the adjustable range of the lowest backlight level [ the first lowest backlight level and the second lowest backlight level ] is [1, 15],8 is the default lowest backlight level, and the selection of the lowest backlight level is {1,2,3,4,5,6,7,8,9, 10, 11, 12, 13, 14, 15}, then there are 6 lowest backlight levels between the first lowest backlight level and the default lowest backlight level, and there are 6 lowest backlight levels between the default lowest backlight level and the second lowest backlight level. Assuming that the lowest backlight level adjustable range [ first lowest backlight level, second lowest backlight level ] is set to [2, 14],8 is the default lowest backlight level, and the lowest backlight level is selected to be {2,4,6,8, 10, 12, 14}, then there are 2 lowest backlight levels between the first lowest backlight level and the default lowest backlight level, and 2 lowest backlight levels between the default lowest backlight level and the second lowest backlight level.
Assuming that the highest backlight level adjustable range [ first highest backlight level, second highest backlight level ] is [1747, 2347], the default highest backlight level is 2047, and the selection of the highest backlight levels is {1747, 1847, 1947, 2047, 2147, 2247, 2347}, then there are 2 highest backlight levels between the first highest backlight level and the default highest backlight level, and 2 highest backlight levels between the default highest backlight level and the second highest backlight level.
It can be understood that, in the electronic device, two progress bars may be added: a lowest backlight level control progress bar and a highest backlight level control progress bar. Then, acquiring a current lowest backlight grade and/or a current highest backlight grade adjusted by the user on the lowest backlight grade control progress bar and/or the highest backlight grade control progress bar; the electronic device adjusts the screen backlight brightness according to the current lowest backlight level, and/or the current highest backlight level. The lowest backlight level control progress bar may also be referred to as a lowest backlight level brightness control progress bar, and the highest backlight level control progress bar may also be referred to as a highest backlight level brightness control progress bar. The screen backlight brightness may also be referred to as screen display brightness.
It can be understood that the present application adjusts the screen brightness in the following manner, as follows:
(1) Adjusting screen backlight brightness by user's adjusting operation of the lowest backlight level control bar and/or the highest backlight level control bar
When the user slides the lowest backlight level control bar and/or the highest backlight level control bar, the electronic device responds to the sliding operation of the user to obtain the current lowest backlight level and/or obtain the current highest backlight level, so that the lowest screen backlight brightness and/or the highest screen backlight brightness of the electronic device are/is adjusted.
(2) By adjusting the configuration curve, the backlight brightness of the screen is adjusted
The value storage database can be adjusted to monitor through a manual backlight level control bar to obtain the current lowest backlight level (minBrightness) and/or the current highest backlight level (maxBrightness); then, the current lowest screen backlight brightness (x) is calculated min is currently ) And/or, current maximum screen backlight brightness (x) max is currently ) (ii) a Interpolation of value (minBrightness, x) using an automatic backlight algorithm min is currently )(maxBrightness，x max is currently ) And readjusting the configuration curve so as to adjust the screen backlight brightness.
For example, the lowest backlight level adjustable range if set to [2, 14]]Three gradients to 2 can be set on the left side of the default value of 8, and 3 gradients to 14 can be set on the right side, i.e. the adjustable range of the current lowest backlight level (minBrightness) is [2, 14]]The lowest screen backlight luminance (nit) varies linearly, which may be according to L min Default /x min Default ＝L min is currently /x min is currently To obtain 8/10= minBrightness/x min is currently ，x min is currently For the current lowest screen backlight brightness, find x min is currently 。
For example, the highest backlight level adjustable range if set to [1747, 2347]I.e. the current highest backlight level (maxBrightness) adjustable range is 1747, 2347]Can be according to L max default /x max default ＝L max is currently /x max is currently (ii) a 2047/450= maxBrightness/x is obtained max is currently ，x max is currently For the current highest screen backlight brightness, find x max is currently 。
It should be noted that, in any way, the highest backlight level and/or the lowest backlight level corresponding to the backlight level control bar may be adjusted, so as to achieve the purpose of changing the display brightness of the screen.
According to the technical scheme, the adjustable range of the screen backlight brightness is readjusted by dynamically adjusting the lowest backlight grade and/or the highest backlight grade; alternatively, the profile is regenerated to reduce the discomfort of different users with different light sensitivity.

The following specifically describes each constituent component of the mobile phone with reference to fig. 6:
RF circuit 610 may be used for receiving and transmitting signals during a message transmission or a call, and in particular, for receiving downlink information from a base station and processing the received downlink information to processor 680; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 610 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 610 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), general Packet Radio Service (GPRS), code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), long Term Evolution (LTE), email, short Messaging Service (SMS), and the like.
The memory 620 may be used to store software programs and modules, and the processor 680 may execute various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 620. The memory 620 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 620 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 630 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also referred to as a touch screen, may collect touch operations of a user (e.g., operations of the user on the touch panel 631 or near the touch panel 631 by using any suitable object or accessory such as a finger or a stylus) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 631 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 680, and can receive and execute commands sent by the processor 680. In addition, the touch panel 631 may be implemented using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 630 may include other input devices 632 in addition to the touch panel 631. In particular, other input devices 632 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 640 may be used to display information input by a user or information provided to the user and various menus of the mobile phone. The Display unit 640 may include a Display panel 641, and optionally, the Display panel 641 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 631 can cover the display panel 641, and when the touch panel 631 detects a touch operation thereon or nearby, the touch panel is transmitted to the processor 680 to determine the type of the touch event, and then the processor 680 provides a corresponding visual output on the display panel 641 according to the type of the touch event. Although in fig. 6, the touch panel 631 and the display panel 641 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 631 and the display panel 641 may be integrated to implement the input and output functions of the mobile phone.
The handset may also include at least one sensor 650, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 641 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 641 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the gesture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.
Audio circuit 660, speaker 661, and microphone 662 can provide an audio interface between a user and a cell phone. The audio circuit 660 may transmit the electrical signal converted from the received audio data to the speaker 661, and convert the electrical signal into an audio signal through the speaker 661 and output the audio signal; on the other hand, the microphone 662 converts the collected sound signal into an electrical signal, which is received by the audio circuit 660 and converted into audio data, which is then processed by the audio data output processor 680 and sent to, for example, another cellular phone via the RF circuit 610, or output to the memory 620 for further processing.
Wi-Fi belongs to short-distance wireless transmission technology, and a mobile phone can help a user to receive and send emails, browse webpages, access streaming media and the like through a Wi-Fi module 670, and provides wireless broadband internet access for the user. Although fig. 6 shows a Wi-Fi module 670, it is understood that it does not belong to the essential constitution of the handset and can be omitted entirely as needed within the scope of not changing the essence of the application.
The processor 680 is a control center of the mobile phone, and connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 620 and calling data stored in the memory 620, thereby performing overall monitoring of the mobile phone. Optionally, processor 680 may include one or more processing units; preferably, the processor 680 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.
