The display screen can be provided with a plurality of brightness levels, and the brightness of the display screen is adjusted by adjusting the brightness levels. In the related art, a problem of overlarge brightness span may exist in a display screen under different brightness levels, and the problem of abrupt brightness change may be caused by the overlarge brightness span of the display screen under different brightness levels, so that human eyes feel that the display screen flickers.
Referring to fig. 1 and 2, a brightness calibration method according to an embodiment of the application may be used in an electronic device 10. The electronic device 10 includes a display screen 12 and the brightness calibration method includes:
01: acquiring brightness values of the display screen 12 at a plurality of preset brightness levels, wherein the plurality of preset brightness levels comprise adjacent first brightness levels and second brightness levels;
02: when the difference between the first brightness value corresponding to the first brightness level and the second brightness value corresponding to the second brightness level is larger than the preset difference, a virtual brightness level is added between the first brightness level and the second brightness level, and the brightness value corresponding to the virtual brightness level is located between the first brightness value and the second brightness value.
Referring to fig. 2 and 3, a brightness calibration device 14 according to an embodiment of the application may be used in an electronic apparatus 10. The electronic device 10 comprises a display screen 12 and the brightness calibration means 14 comprise an acquisition module 141 and a processing module 142.
The luminance calibration method of the present application may be implemented by the luminance calibration device 13 of the present embodiment, where step 01 may be implemented by the obtaining module 141, and step 02 may be implemented by the processing module 142, that is, the obtaining module 141 may be configured to obtain luminance values of the display screen 12 at a plurality of preset luminance levels, where the plurality of preset luminance levels includes adjacent first luminance levels and second luminance levels. The processing module 142 may be configured to increase a virtual luminance level between the first luminance level and the second luminance level when a difference between the first luminance value corresponding to the first luminance level and the second luminance value corresponding to the second luminance level is greater than a preset difference, where the luminance value corresponding to the virtual luminance level is located between the first luminance value and the second luminance value.
In the above-mentioned luminance calibration method and luminance calibration device 14, when the difference between the luminance values of two adjacent luminance levels is greater than the preset difference, a virtual luminance level is added between the two luminance levels, where the luminance value corresponding to the virtual luminance level is located between the first luminance value and the second luminance value, so that the adjustment of luminance can be smoother.
In some embodiments, the electronic device 10 may include a smart phone, tablet, smart watch, smart bracelet, etc. with a display screen 12, without limitation. The embodiment of the application is described with respect to the electronic device 10 being a smart phone.
In some embodiments, each preset brightness level may be set using a brightness calibration application package (Android application package, APK) and then the brightness value of the display screen 12 at each preset brightness level is obtained.
The preset brightness levels include a first brightness level and a second brightness level, the first brightness level and the second brightness level are any two adjacent preset brightness levels, each brightness level in the plurality of preset brightness levels can be respectively used as the first brightness level, the next preset brightness level in the first brightness level is used as the second brightness level, and the brightness calibration method of the embodiment of the application is executed for a plurality of times.
When the difference between the first luminance value corresponding to the first luminance level and the second luminance value corresponding to the second luminance level is greater than the preset difference, it is indicated that the luminance span is relatively large, and therefore, a virtual luminance level may be inserted between the first luminance level and the second luminance level.
In one embodiment, to increase visibility in sunlight, the display 12 supports a highlight mode (High Brightness Mode, HBM) function, and by setting a screen register, the display 12 can be switched from a normal mode (normal mode) to HBM, and a sudden change in brightness occurs due to the non-uniform brightness of the normal mode and HBM. Therefore, the luminance calibration method according to the embodiment of the application can sort the luminance levels of the normal mode and the HBM to be used as the preset luminance level, then judge whether the difference between the luminance values of the adjacent first luminance level and second luminance level is larger than the preset difference, and if the difference between the luminance values is larger than the preset difference, increase the virtual luminance level between the adjacent first luminance level and second luminance level, wherein the luminance value corresponding to the virtual luminance level is located between the first luminance value and the second luminance value.
The virtual luminance level that increases between the first luminance level and the second luminance level may be one or more, and is not particularly limited herein. After the virtual brightness level is increased, the preset brightness level and the virtual brightness level can be adopted for common adjustment in the subsequent application process of the display screen 12 of the electronic device 10, so that the adjustment of brightness is smoother.
Referring to fig. 4, in some embodiments, the electronic device 10 includes a light sensor 16 located below the display screen 12, where the light sensor 16 is configured to detect brightness data of the display screen 12, and step 01 (obtaining brightness values of the display screen 12 at a plurality of preset brightness levels) includes:
012: the corresponding luminance value is determined from luminance data of the display screen 12 at a plurality of preset luminance levels.
In some embodiments, electronic device 10 includes a light sensor 16 positioned below display screen 12, light sensor 16 being configured to detect luminance data of display screen 12. Step 012 may be implemented by the acquisition module 141, that is, the acquisition module 141 may be configured to determine the corresponding luminance value according to luminance data of the display screen 12 at a plurality of preset luminance levels.
In this manner, the off-screen light sensor 16 may be employed to detect an actual luminance value of the display screen 12, and based on the detected actual luminance value, a virtual luminance level may be increased between a first luminance level and a second luminance level having a difference in luminance value greater than a preset difference, to optimize the luminance smoothness of the display screen 12. In addition, the brightness is adjusted based on the detected actual brightness value, so that the brightness can be adjusted more accurately, and the consistency of the plurality of display screens 12 in the same type is better, that is, the actual brightness of the same brightness level on the plurality of display screens 12 in the same type is similar.
To increase the screen duty cycle, electronic device 10 may employ an off-screen light sensation (light sensor 16 disposed below display screen 12), where light sensor 16 is configured to detect the brightness of display screen 12 to obtain brightness data from which a display brightness value of display screen 12 may be determined. The light sensor 16 for detecting the brightness data of the display screen 12 is not used for detecting the ambient light, so that the light sensor 16 has specific functions and accurate brightness data. The light sensor 16 for detecting luminance data of the display 12 may also be used for detecting ambient light, so that the light sensor 16 may be multiplexed, enabling a reduction in the light sensors required by the electronic device 10. In order to reduce measurement errors of the light sensors 16, a plurality of light sensors 16 may be used to make measurements while detecting the brightness of the display screen 12 to obtain brightness data.
In order to make the brightness data obtained by the light sensor 16 more accurate, the electronic device 10 may be placed in a dark environment when the light sensor 16 detects, thereby reducing the influence of ambient light. In a dark environment, each preset brightness level may be set using the brightness calibration APK, and then the light sensor 16 detects brightness data of the display screen 12 at each preset brightness level, so that the brightness data detected by the light sensor 16 may be processed to obtain a corresponding brightness value.
Referring to fig. 5, in some embodiments, the first brightness level is smaller than the second brightness level, and the brightness calibration method includes:
03: and removing the second brightness level when the first brightness value is larger than the second brightness value.
Referring to fig. 6, in some embodiments, the first brightness level is less than the second brightness level, and the brightness calibration device 14 includes a removal module 143. Step 03 may be implemented by the removal module 143, that is, the removal module 143 may be configured to remove the second brightness level when the first brightness value is greater than the second brightness value.
In this way, abnormal brightness levels can be removed.
Specifically, the first luminance level is smaller than the second luminance level, that is, in theory, the luminance value corresponding to the second luminance level should be greater than the luminance value corresponding to the first luminance level, so if the first luminance value actually detected is greater than the second luminance value, this indicates that in actual situations, as the luminance level increases, an abnormal situation occurs in which the luminance value does not rise and fall, and therefore, the abnormal luminance level can be removed, that is, the second luminance level is removed. After the abnormal brightness level is removed, in the application process of the display screen 12 of the subsequent electronic device 10, the preset brightness level and the virtual brightness level with the abnormal brightness level removed can be adopted for common adjustment, so that the adjustment of the brightness is more accurate and smoother.
Referring to fig. 7, in some embodiments, the first brightness level is smaller than the second brightness level, and the brightness calibration method includes:
04: and determining that the difference between the first brightness value and the second brightness value is larger than the preset difference when the first brightness value is smaller than the preset brightness value and the amplification of the second brightness value relative to the first brightness value is larger than the first preset amplification.
Referring to fig. 8, in some embodiments, the first brightness level is less than the second brightness level, and the brightness calibration device 14 includes a first determination module 144. Step 04 may be implemented by the first determining module 144, that is, the first determining module 144 may be configured to determine that the difference between the first luminance value and the second luminance value is greater than the preset difference when the first luminance value is less than the preset luminance value and the increase of the second luminance value relative to the first luminance value is greater than the first preset increase.
Thus, it can be accurately determined whether the difference between the first luminance value and the second luminance value is greater than a preset difference.
Specifically, at low luminance, since human eyes are sensitive to luminance variation, luminance is adjusted at low luminance, human eyes easily feel luminance mutation, so that whether the first luminance value is smaller than a preset luminance value can be judged, when the first luminance value is smaller than the preset luminance value, whether the second luminance value is amplified more than the first preset amplification relative to the first luminance value can be judged, if the amplification is amplified more than the first preset amplification, it is indicated that human eyes feel luminance mutation at the moment, and it can be determined that the difference between the first luminance value and the second luminance value is greater than the preset difference. The preset luminance value may be 70 nit (nit), and the first preset increase may be 3%, that is, when the first luminance value is less than 70 nit and the increase of the second luminance value relative to the first luminance value is greater than 3%, it may be determined that the difference between the first luminance value and the second luminance value is greater than the preset difference.
Referring to fig. 9, in some embodiments, the brightness calibration method includes:
05: when the first brightness value is larger than the preset brightness value and the amplification of the second brightness value relative to the first brightness value is larger than the second preset amplification, the difference between the first brightness value and the second brightness value is larger than the preset difference, and the second preset amplification is larger than the first preset amplification.
Referring to fig. 8, in some embodiments, the luminance calibration device 14 includes a second determination module 145. Step 05 may be implemented by the second determining module 145, that is, the second determining module 145 may be configured to determine that the difference between the first luminance value and the second luminance value is greater than the preset difference when the first luminance value is greater than the preset luminance value and the second luminance value is greater than the second preset increase relative to the first luminance value.
Thus, it can be accurately determined whether the difference between the first luminance value and the second luminance value is greater than a preset difference.
Specifically, in the case of high brightness, since the human eye is relatively insensitive to brightness variation, brightness is adjusted under the high brightness, the human eye is not easy to feel brightness abrupt change, so that whether the first brightness value is larger than the preset brightness value can be judged, when the first brightness value is larger than the preset brightness value, whether the second brightness value is larger than the second preset brightness value or not can be judged, if the second brightness value is larger than the second preset brightness value, the human eye can feel brightness abrupt change at the moment, and the difference between the first brightness value and the second brightness value can be determined to be larger than the preset difference. The preset luminance value may be 70 nit (nit), and the first preset increase may be 5%, that is, when the first luminance value is less than 70 nit and the increase of the second luminance value relative to the first luminance value is greater than 5%, it may be determined that the difference between the first luminance value and the second luminance value is greater than the preset difference.
Referring to fig. 10, in some embodiments, the brightness calibration method includes:
06: and when the preset input information is received, determining that the difference between the first brightness value and the second brightness value is larger than the preset difference.
Referring to fig. 11, in some embodiments, the luminance calibration device 14 includes a third determination module 146. Step 06 may be implemented by the third determining module 146, that is, the third determining module 146 may be configured to determine that the difference between the first luminance value and the second luminance value is greater than the preset difference when the preset input information is received.
Thus, it can be accurately determined whether the difference between the first luminance value and the second luminance value is greater than a preset difference.
Specifically, the brightness corresponding to the first brightness level and the second brightness level may be displayed for the user to watch, the user may give an evaluation whether the difference between the first brightness value and the second brightness value is greater than the preset difference according to his own watching experience, and then input the evaluation to the electronic device 10, for example, the electronic device 10 provides two options of yes and no, if yes, the user may consider that preset input information is received at this time, which indicates that the user considers that the difference between the first brightness value and the second brightness value is greater than the preset difference; if the user selects no, the user can be regarded as not receiving the preset input information, which indicates that the difference between the first brightness value and the second brightness value is smaller than the preset difference. Thus, the user can adjust unsatisfactory low brightness or other brightness parts according to own preference, the user experience can be optimized, and the brightness smoothness can be adjusted according to own habits of the user.
Referring to fig. 12, in some embodiments, the brightness calibration method includes:
07: the display screen 12 is controlled to reduce the color components of the display screen at a preset ratio at the virtual luminance level such that the luminance value corresponding to the virtual luminance level is located between the first luminance value and the second luminance value.
Referring to fig. 13, in some embodiments, the brightness calibration device 14 includes a control module 147. Step 07 may be implemented by the control module 147, that is, the control module 147 may be configured to control the display screen 12 to reduce the color components of the display screen by a preset ratio under the virtual brightness level such that the brightness value corresponding to the virtual brightness level is located between the first brightness value and the second brightness value.
In this way, the display luminance of the display screen 12 can be adjusted by adjusting the color components of the display screen.
Specifically, the display 12 may be an OLED display, where the brightness of the display is typically adjusted by controlling a screen register, and different brightness levels may correspond to different settings of the screen register. Because the output capability of the screen may not be enough due to the limitation of the number of bits of the screen register, and the luminance span between adjacent luminance levels is too large, so that a virtual luminance level may be increased between the first luminance level and the second luminance level, wherein the screen register setting value of the virtual luminance level may be the same as the screen register setting value of the second luminance level, and in order to reduce the actual display luminance of the virtual luminance level, the color component (e.g., RGB component) of the display screen may be reduced according to a preset ratio, so that the actual luminance value corresponding to the virtual luminance level is located between the first luminance value and the second luminance value, and thus, the limitation of the luminance adjustment capability of the display screen 12 itself may be broken through, and the screen luminance smoothness may be optimized.
It is noted that the specific values mentioned above are only for the purpose of illustrating the implementation of the present application in detail and are not to be construed as limiting the present application. In other examples or embodiments or examples, other values may be selected according to the present application, without specific limitation.
