Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of means consistent with some aspects of the present disclosure, as recited in the appended claims.

As shown in FIG. 1 , an embodiment of the present disclosure provides a display brightness adjustment method, including:

S110: Detect a brightness adjustment operation acting on the terminal;

S120: According to the brightness adjustment operation, adjust the display brightness when a part of the display screen is lit;

S130: Control the display of a local area of the display screen according to the adjusted display brightness.

The embodiments of the present disclosure can be applied to various terminals that support the display brightness adjustment method.

For example, the terminal may include a mobile phone, a tablet computer, or a wearable device.

The terminal includes a display screen, and the display screen may be an OLED display screen, or a liquid crystal display screen capable of independently driving different parts of the backlight to light up, or the like.

In S110, a brightness adjustment operation is detected, and the brightness adjustment operation may be: a manual operation acting on a physical button on the terminal, a touch operation acting on a touch screen, or an audio collection module (for example, a microphone ) captured voice actions.

In a word, if the brightness adjustment operation triggers the display brightness of the partial lighting of the display screen, the display brightness of the partial display of the display screen is adjusted according to the brightness adjustment operation.

For example, the brightness adjustment operation is an operation instructing to increase the display brightness, so as to increase the display brightness when a part of the display screen is turned on. For another example, the brightness adjustment operation is an operation instructing to reduce the display brightness, and the display brightness when a part of the display screen is turned on is reduced.

Specifically, how to distinguish the currently detected brightness adjustment operation is for the brightness adjustment of the partial display of the display screen or the brightness adjustment of the full screen display of the display screen, which can be determined according to the current display state of the display screen.

For example, if the current display screen is in a full-screen display state, it is determined that the currently detected brightness adjustment operation is the brightness adjustment during full-screen display of the display screen; otherwise, it can be considered that the currently detected brightness adjustment operation is the brightness during partial display of the display screen. adjust.

For another example, if the current display screen is in a full-screen display state, it is determined that the currently detected brightness adjustment operation is the brightness adjustment for the full-screen display of the display screen. The currently detected brightness adjustment operation is the partial display brightness adjustment of the display screen.

When the display screen is in a full-screen display state, the entire screen of the display screen is in a working state, and the entire screen can be lit.

When the display screen is in the partial display state of partial display, part of the screen of the display screen is in a working state, and part of the display screen can be lit as much as possible.

In some cases, the partial display state may be a special state of the screen-off state of the display screen. The display area where the display screen is partially lit may be very small, only a predetermined percentage of the display area of the display screen, and the predetermined percentage may be less than 50%, or even less than 25%, for example, 10% or 20% or 15% or 5%. %, or even 3%.

For example, when the display screen is partially lit, it is mainly used to notify time information, date information, remaining power, signal strength status of the terminal, and/or unread information through the lit part in the off-screen state. display of information.

In this way, in the screen-off state, it is used to check the time, the remaining power of the terminal and/or the signal strength and other information at any time in the part that can be lit through the display screen.

In other embodiments, if the terminal including the display screen is a fingerprint unlocking terminal, the lighted part can also be used to display a fingerprint detection image, and the fingerprint detection image can be used to indicate an area for fingerprint detection. A fingerprint module can be arranged below the fingerprint detection area, which can scan fingerprints.

In the embodiment of the present disclosure, when the display screen is in partial display, the brightness can also be adjusted based on user input, so as to reduce the phenomenon of poor visual effect caused by excessively high or low brightness during partial display, and improve the display of the display screen Effect.

The adjustment of the display brightness of the partially lit display screen can be achieved by at least one of the following:

When adjusting the partial lighting of the display screen, the voltage of the display driving signal, for example, increasing the voltage of the driving signal can increase the display brightness, and reducing the voltage of the driving signal can reduce the display brightness.

When the display screen is partially lit, the duty cycle of the display drive signal is adjusted. For example, increasing the duty cycle of the drive signal can increase the display brightness, and reducing the duty cycle of the drive signal can reduce the display brightness.

In one embodiment, the control of the display brightness of the partial lighting of the display screen included in S130 may control the display brightness of the partial lighting of the display screen according to the adjusted display brightness as an average brightness value.

In another embodiment, S130 may include: determining a brightness interval according to the adjusted display brightness and the brightness offset value, and controlling the display brightness of the partial lighting of the display screen to be within the brightness interval.

In some embodiments, as shown in Figure 2, the method further includes:

S210: After adjusting the display brightness, detect the ambient brightness;

S220: Establish a corresponding relationship between the ambient brightness and the adjusted display brightness;

S230: After establishing the corresponding relationship, control the display brightness of the partial lighting of the display screen according to the established corresponding relationship.

For example, at the first moment, the corresponding relationship between the ambient brightness and the adjusted display brightness is established; and at the second moment, according to the corresponding relationship, the display brightness of the partial lighting of the display screen is controlled, wherein the second moment is later than the first moment. time. The first moment here can be any moment after the brightness is adjusted and after the ambient brightness is detected. The second time can be any time after the first time.

After the partial lighting display brightness adjustment is performed based on the brightness adjustment operation, in order to facilitate subsequent intelligent control, the user does not need to control the display brightness when the display screen is partially illuminated through operation input every time. After an adjustment of the display brightness, the terminal will establish a corresponding relationship by itself.

The establishment of the corresponding relationship here may include:

When the corresponding relationship is not established in the terminal, the corresponding relationship between the ambient brightness and the target brightness of the partially lit display screen is established for the first time;

and / or,

When the terminal has established a corresponding relationship, according to the adjusted display brightness, the corresponding relationship between the ambient brightness and the partially lit target brightness of the display screen is updated.

In this way, when the subsequent display screen is partially lit, a corresponding relationship can be established to control the display brightness of the partially lit display screen.

In one embodiment, according to the corresponding relationship, controlling the display brightness of the partial lighting of the display screen includes:

Detect ambient brightness, for example, detect ambient brightness through a light sensor included in the terminal, or receive ambient brightness from peripherals;

According to the detected ambient brightness, query the corresponding relationship to obtain the target brightness under the currently detected ambient brightness;

According to the target brightness, control the brightness of the partial lighting of the display screen.

For example, the ambient brightness is detected periodically or irregularly, so as to trigger a local quantitative adjustment of the display brightness of the display screen on a regular or irregular basis.

For another example, when the display screen enters a state of being partially lit, the ambient brightness is detected, and then the brightness of the partially illuminated display screen is controlled in combination with the corresponding relationship and the detected ambient brightness. Then, the ambient brightness is detected periodically, for example, the ambient brightness is detected in a cycle of 2 minutes. When it is detected that the change of the ambient brightness is greater than the preset threshold, the brightness adjustment of the partial lighting of the display screen can be adjusted again according to the corresponding relationship, so as to realize the automatic dynamic adjustment of the display brightness when the display screen is partially illuminated.

In some cases, the display brightness when the display screen is partially lit may not be divided into brightness gears. Through repeated adjustment, a corresponding relationship between different ambient brightness and the display brightness displayed by the display screen can be finally established, so as to precisely control the display screen. Precise control of local lighting.

Different brightness levels can be used in different terminal states. For example, if the current remaining power of the terminal is less than the preset value, when performing local lighting, the brightness level with lower brightness can be used. Otherwise, the brightness level with higher brightness can be used. Brightness level.

Of course, during specific implementation, the current brightness level of the display screen for local lighting can also be selected according to user settings.

In some embodiments, the method further includes:

Detect gear adjustment operation,

According to the gear adjustment operation, determine the brightness gear of the display screen for local adjustment.

If the display screen is partially lit, if the user feels that it is too bright or too dark, and wants to quickly adjust the brightness, you can first adjust the brightness level with a wider adjustment range.

In one embodiment, the brightness adjustment operation of adjusting the brightness level and triggering the brightness adjustment of the local display in step S110 may be a brightness adjustment operation acting on different devices of the terminal. For example, in the display settings of the display screen, you can touch the The touch operation of the screen detection can be used to adjust the brightness level of the partial display.

When the display information is partially displayed, the brightness adjustment of the partial point amount not directly across the gears can be performed through key detection.

In one embodiment, the brightness level may be divided into two levels, eg, a high brightness level and a low brightness level.

In another embodiment, the brightness level may exceed two levels, such as 3rd level or 4th level. As shown in Figure 3, the display screen can support 4 brightness levels for partial display. Each of the 4 brightness levels has its own level range. Under different brightness levels, there may be brightness intervals corresponding to different ambient brightness.

FIG. 3 shows that there are four brightness levels, namely brightness level 1 to brightness level 4. After a period of time, the brightness intervals of the four brightness levels have all changed.

In one embodiment, the display brightness is divided into at least two brightness levels; the display brightness is at least divided into two brightness levels; and the correspondence between the ambient brightness and the adjusted display brightness is established, including:

According to the adjusted display brightness and the brightness range of the currently adjusted brightness level of the display screen, a corresponding relationship between the currently located brightness level after the adjustment of the brightness range and the ambient brightness is established.

For example, one brightness level corresponds to one brightness interval, and the brightness interval includes: an upper limit of the interval and a lower limit of the interval.

In the embodiment of the present disclosure, adjusting the brightness range of the brightness level of the display screen according to the adjusted display brightness can be realized by adjusting the upper limit of the range and the lower limit of the range.

For example, if the current brightness adjustment operation instructs to increase the display brightness, the adjusted display brightness may be the upper limit of the interval of the brightness level where the display screen is currently located. The current brightness adjustment operation indicates to reduce the maximum display brightness, and the adjusted display brightness can be the lower limit of the interval where the display screen is currently located.

In one implementation, if the adjusted display brightness has stepped into other brightness gears adjacent to the current brightness gear of the display screen, other brightness gears adjacent to the previous brightness gear according to the adjusted display brightness The position in the brightness interval corresponding to the bit determines the combination of the two brightness levels. If it is determined to combine, the two brightness levels are combined to form one brightness level, and the brightness level of the combined brightness level is the union of the brightness levels of the two brightness levels before the combination.

For example, if the adjusted display brightness is within a preset interval of adjacent brightness levels of the current brightness level, the two brightness levels are merged. For example, brightness gear 1 and brightness gear 2 are adjacent, and brightness gear 1 is the current brightness gear of the display screen; if the difference between the adjusted display brightness and the middle value in the brightness interval of brightness gear 2 If the value is less than the preset value, it can be regarded as the preset interval.

For another example, for example, brightness gear 1 and brightness gear 2 are adjacent, and brightness gear 1 is the current brightness gear of the display screen; if the brightness of brightness gear 1 is greater than the display brightness of brightness gear 2, if the adjusted brightness If the ratio of the difference between the display brightness of , and the upper limit of the interval of brightness level 2 to the brightness difference of the brightness level of brightness level 2 reaches a specific ratio, it can be considered that brightness level 1 and brightness level 2 need to be merged.

In one embodiment, the method further includes:

Determine whether to start the AOD display mode on the off-screen display; wherein, the display screen is partially lit in the AOD display mode;

After starting the AOD display mode, start the monitoring of the preset input module that detects the brightness adjustment operation;

Detects brightness adjustment operations on the terminal, including:

The processing module of the display screen determines whether a brightness adjustment operation is detected according to the interrupt signal generated by the operation of the preset input module.

The AOD display mode here is a special display mode, which is a specific display state with partial lighting.

In the AOD display mode, the display screen is in an off state as a whole, and only a small area is lit, so as to save the display power consumption of the terminal.

If the terminal decides to enter the AOD display mode in the partial lighting state after exiting the full-screen display state, it will start to monitor the brightness adjustment operation of adjusting the display brightness of the display screen in the AOD display mode, thereby starting the corresponding preset input module. monitoring.

For example, in the operating system, a monitoring component is set, the monitoring component monitors the input signal corresponding to the preset input module, and transmits it to the processing module of the terminal in time (the processing module includes but is not limited to the terminal processor ( CentreProcessor Unit, CPU) and/or application processor (Application Processor, AP), the processing module will determine the trigger signal for adjusting the display brightness when the partial lighting is detected according to the input signal, so as to reset the partial lighting of the display screen The brightness value is used to control the output of the driving signal of the driving circuit of the display screen.

The default input module can establish a connection with the processing module, for example, the pins of the default input module are connected with the GPIO pins in the general purpose input/output (General Purpose Input/Ooutput) interface of the processing module. At this time, the interrupt signal can be a different voltage and/or current value detected on the GPIO pin. The interrupt signal is used to transmit the display brightness adjustment that triggers the partial lighting of the display screen, which has the characteristics of simple implementation and high efficiency.

In one embodiment, the preset input module includes:

side keys of terminals containing a display;

or,

Contains the rear touch panel of the display.

For example, the side keys of the terminal may include a volume adjustment key and/or a power key, so the volume adjustment key and/or the power key may be reused to adjust the display brightness when the display screen is partially lit.

In one embodiment, a touch panel may be disposed on the back of the display screen, usually a touch panel in a touch screen in which the touch panel and the display screen are stacked. For example, the display area of the touch panel may be smaller than that of the display screen, and the display brightness of the partially lit display screen may be adjusted by touching the back of the display screen.

The specific terminal determines whether to detect the brightness adjustment operation that triggers the partial lighting of the display screen, which can be determined according to the parameters of the brightness adjustment operation detected by each preset input module.

For example, in one embodiment, assuming that the preset input module is the back touch panel of the display screen, it can be determined according to the sliding track of the touch operation acting on the back touch panel of the display screen, for example, the detected If the sliding track is a predetermined track, it is determined that a brightness adjustment operation that triggers partial lighting of the display screen to adjust the display brightness is detected.

In some embodiments, the side keys include: volume adjustment keys;

The processing module of the display screen determines whether the brightness adjustment operation is detected according to the interrupt signal generated by the operation of the preset input module, including:

Determine the operation parameters acting on the preset input module according to the interrupt signal, and determine whether the brightness adjustment operation acting on the volume adjustment key is a brightness adjustment operation;

When the parameter value of the operation parameter is a preset value, the brightness adjustment operation when the operation acting on the volume adjustment key is determined.

For example, the operation acting on the volume adjustment key may also be a volume adjustment operation, which is used to trigger the volume adjustment. In this case, it is necessary to distinguish whether the operation acting on the volume adjustment key is a volume adjustment operation or a brightness adjustment operation. In the embodiments of the present disclosure, the distinction is made according to operating parameters.

If it is determined that the operation acting on the volume adjustment key is a brightness adjustment operation, it is determined that a brightness adjustment operation that triggers the brightness adjustment when the display screen is partially lit is detected.

Figure 4 shows the side of a terminal showing the side keys of the terminal. The side key can be the volume adjustment key of the terminal. The volume adjustment key can be reused as the brightness adjustment when the display screen is partially lit.

Operating parameters include:

The number of times the volume adjustment key is pressed continuously;

and / or,

How long the volume control key is pressed.

For example, a single short press and/or a long press detected by the volume adjustment key may be considered to have detected a volume adjustment operation, otherwise, a brightness adjustment operation may be considered to be detected. For another example, if the volume adjustment key detects two consecutive short presses, it may be considered that a brightness adjustment operation is detected; otherwise, the brightness adjustment operation detected by the volume adjustment key may be considered as a volume adjustment operation.

In this way, the volume adjustment key of the terminal is multiplexed to realize the detection of the brightness adjustment operation of the display brightness adjustment in which the display screen is partially lit.

In one embodiment, the volume adjustment keys include: a volume up key and a volume down key. If it is detected that the operation acting on the volume up key is a brightness adjustment operation, in S120, the display brightness of the partial lighting of the display screen is increased. If it is detected that the operation acting on the volume down key is a brightness adjustment operation, in S120, the display brightness of the partial lighting of the display screen is reduced.

This example provides a display brightness adjustment method that can be applied to AOD display in AOD display mode.

The AOD brightness in the related art is single and cannot be adjusted, while the human eye has different perception curves and different requirements for brightness. Therefore, the solution of fixed brightness or brightness that cannot be adjusted will bring a relatively poor user experience. , the proposed embodiments of the present disclosure are dedicated to an optimization and implementation solution to solve this problem.

AOD display is to display content by lighting part of the screen, so that the display of content can be completed under the condition of low power consumption. Due to the working mode of the OLED screen, part of the area can be lit for content display. At this time, the entire screen works at low In the power consumption mode, this working mode can bring an excellent user experience, allowing users to easily view the time, information, etc. in the standby state. The brightness displayed by AOD has multiple gears, according to different brightness. However, since different people have different usage habits, they can only be adjusted according to a fixed preset during use, and the user cannot adjust the display brightness of the AOD in the current environment. Therefore, the embodiment of the present disclosure proposes a The scheme of adjusting according to the volume key and matching the user's usage habits in the AOD state of the off-screen display, the specific scheme of the embodiment of the present disclosure is as follows:

Step 1: When the mobile phone is on the screen, the AOD display mode is first adjusted according to the preset brightness at the factory.

Step 2: When the user feels that the brightness of the AOD is too low to be seen clearly in the current environment, or the brightness is too excessive to be dazzling, double-click the volume down or volume up to adjust the brightness of the AOD displayed on the screen.

Step 3: When adjusting the brightness in step 2, record the current light sensor data, and record the current match, and when the mobile phone is at the brightness again, it will automatically adjust to the brightness that the current user self-adjusted.

Step 4: Adjust the optimization of the AOD display by matching the brightness and the current AOD display in Steps 2 and 3.

This solution can perfectly complete the brightness adjustment in the AOD display mode, and is in line with the usage habits of each user. Through these optimizations, the user experience can be well improved.
