The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
The embodiment of the invention provides a brightness adjusting method, which can be applied to an OLED display screen, an LCD display screen and a miniaturized LED display screen, and can also be applied to other display screens provided with independent light-emitting units. In this example, the display screen is provided with a plurality of sending units, each of the sending units corresponds to a pixel, and when adjusting the brightness, as shown in fig. 1, the method includes the following steps:
step S101, analyzing the color of each light-emitting unit to obtain color parameters;
step S102, responding to the color parameter meeting a first condition, and adjusting the brightness of each light-emitting unit.
In this embodiment, by analyzing the color of each light-emitting unit, the color parameter can be obtained based on the color of each light-emitting unit, so that the display brightness can be adjusted based on the color parameter, and the brightness can be adjusted more accurately. Meanwhile, the problem that in the prior art, due to the fact that the brightness is adjusted manually, adjustment needs to be carried out frequently is solved. And the problem that the display brightness is not accurately adjusted due to the fact that the environment brightness is detected through the camera and the brightness sensor and is only adjusted according to the environment brightness and the display brightness cannot be adaptively adjusted according to the display pictures with different color temperatures is solved.
Another embodiment of the present invention provides a brightness adjusting method, as shown in fig. 2, including the following steps:
step S201, acquiring color component values of pixel points corresponding to the light-emitting units in the display content at the current moment;
in this step, the color component values include: a first component value corresponding to red, a second component value corresponding to green, and a third component value corresponding to blue. Namely, the component values of the three colors of red, green and blue in each pixel point are obtained. Each color component value ranges from 0-255.
Step S202, determining the color parameters based on the color component values of the pixel points;
in the specific implementation process of the step, specifically, a target pixel point can be determined from each pixel point according to the size of the color component value of each pixel point, and then the proportion value occupied by the target pixel point is determined based on the number of the target pixel points; and finally, determining the color parameter based on the proportion value.
Step S203, determining a target brightness parameter based on a first condition that the color parameter accords with; determining a brightness change curve based on the current brightness parameter and the target brightness parameter;
in the specific implementation process of the step, a brightness change curve can be calculated in real time, namely, a brightness change curve is calculated based on the current brightness parameter, the target brightness parameter and the adjusting time, and then the brightness parameter corresponding to each adjusting moment is determined to be the target brightness parameter of each light-emitting unit based on the brightness change curve; and gradually adjusting the display brightness of each light-emitting unit based on the target brightness parameter at each adjusting moment. In this step, the adjustment time may be set according to actual needs, for example, the overall range of the luminance parameter is 0-10, the current luminance parameter is 2, the target luminance parameter is 9, and the adjustment time is set to 5 seconds, that is, the luminance needs to be adjusted from 2 to 9 within 5 seconds, so that a luminance change line can be determined.
In the implementation process in this step, when the adjustment time is determined, the adjustment time may be specifically determined according to a difference between the current brightness parameter and the target brightness parameter, that is, when it is determined that the difference between the current brightness parameter and the target brightness parameter is larger than a first specific value, that is, the brightness adjustment amplitude is larger, the longer first time may be determined as the adjustment time, so that the problem of flickering or dim caused by the shorter adjustment time can be prevented. When the difference between the two is determined to be smaller, for example, smaller than the first specific value, which indicates that the amplitude of the brightness adjustment is smaller, the shorter second time may be determined as the adjustment time.
Of course, the step may also determine the brightness change curve based on the target brightness parameter, the current brightness parameter, and the historical brightness curve, that is, select a corresponding brightness change curve line segment from the historical brightness curve according to the target brightness parameter and the current brightness parameter, and gradually adjust the display brightness according to the line segment.
Step S204, adjusting the brightness of each light-emitting unit based on the brightness parameter corresponding to each adjustment time in the brightness parameter variation curve.
In this step, when the brightness is adjusted, the adjustment may be performed in a predetermined time unit, for example, the display brightness may be adjusted stepwise in a time unit per second or in a time unit per 2 seconds according to the brightness change line,
in the embodiment, the brightness change curve is determined, and then the screen display brightness is adjusted based on the brightness change curve, so that the brightness change is more moderate, and the problem of flickering and darkness is prevented.
Another embodiment of the present invention provides a brightness adjusting method, as shown in fig. 3, including the following steps:
step S301, performing area division on a display area to obtain an edge area and a non-edge area, wherein the non-edge area is provided with a plurality of first light-emitting units, and the edge area is provided with a plurality of second light-emitting units;
step S302, acquiring color component values of pixel points corresponding to the first light-emitting units and the second light-emitting units in the display content at the current moment;
in this step, the color component values include: a first component value corresponding to red, a second component value corresponding to green, and a third component value corresponding to blue. Namely, the component values of the three colors of red, green and blue in each pixel point are obtained. Each color component value ranges from 0-255.
Step S303 is to compare the first component value, the second component value, and the third component value of the color component values of the pixels with the corresponding three specific values, and determine a target pixel point when the first component value, the second component value, and the third component value are simultaneously greater than the specific values.
In this step, for example, all three specific values are 250, and when the component values of the three colors of a certain pixel point are all greater than 250, the pixel point is determined to be the target pixel point. In the specific implementation process of the step, the specific values are preset, the three specific values can be the same or different, and each specific value can be adjusted according to actual needs.
Step S304, determining the proportion value of the target pixel points based on the number of the target pixel points;
in the step, the proportion of the white picture in the display picture can be determined by determining the proportion value of the target pixel point, and a foundation is laid for determining the subsequent color parameters.
Step S305, determining the color parameter based on the proportion value;
in this step, when determining the color parameter, the color parameter corresponding to the ratio value may be obtained by searching a ratio-parameter relationship table that is constructed in advance. Specifically, when the ratio-parameter relation table is constructed, the method includes: setting a plurality of proportional thresholds; setting a plurality of color parameters; and establishing a corresponding relation between each proportion threshold and each color parameter so as to construct and obtain a proportion-parameter relation table. The proportional threshold value can be adjusted according to actual needs in the specific implementation process.
Step S306, determining a target brightness parameter based on the first condition met by the color parameter;
in the specific implementation process of the step, the target brightness parameter can also be determined by searching a preset brightness parameter mapping table. Specifically, a plurality of brightness parameters and color parameters can be obtained according to historical information, and then the mapping relation between each brightness parameter and each color parameter is established according to the habit or the preference of a user. A basis is provided for the subsequent determination of the luminance parameter directly from the color parameter.
Step S307, determining a first target brightness parameter corresponding to the non-edge area according to a first specific ratio based on the target brightness parameter; determining a second target brightness parameter corresponding to the edge region at a second illumination-specific ratio based on the target brightness parameter; wherein the second target brightness parameter is less than the first target brightness parameter.
The specific ratio in this embodiment can be set as required, for example, the first specific ratio is 1.05, 1.1, etc. The second specific ratio is 0.9, 0.85, etc., and the second specific ratio is smaller than the first specific ratio. The larger first target brightness parameter and the smaller second target brightness parameter are obtained according to the two different proportions through the target brightness parameter, and a basis is provided for subsequently adjusting different brightness parameters for different display areas.
Step S308, adjusting the brightness of each first light-emitting unit in the non-edge area based on a first target brightness parameter corresponding to the non-edge area; and adjusting the brightness of each second light-emitting unit in the edge area based on a second target brightness parameter corresponding to the edge area.
In this embodiment, since the display content is usually displayed in the non-edge region, and the edge region has little display content, the user does not pay attention to the edge region, and the display brightness of the edge region does not have a great influence on the viewing of the user, a first target brightness parameter that is larger and a second target brightness parameter that is smaller can be obtained according to two different proportions by the target brightness parameter, and then brightness adjustment is performed on the light emitting units in the edge region and the non-edge region, so that the brightness of the non-edge region can be made brighter, and the display brightness of the edge region is darker, and power consumption can be reduced while the viewing of the user is not influenced.
Another embodiment of the present invention provides a brightness adjusting method, as shown in fig. 4, including the following steps:
step S401, determining an application type corresponding to the current display content;
the application types in this step specifically include office software types and non-office software types. Office software type applications include, for example, word, Excel, Power Point, etc., and non-office software type applications include, for example, video software, chat software, shopping software, etc. The application software corresponding to the currently displayed content is determined, and then the type of the application software can be further determined.
Step S402, determining an adjusting mode corresponding to the application type based on the application type;
in this step, the adjustment mode may include an adjustment mode based on the color parameter and an adjustment mode based on the non-color parameter. When the application type is determined to be the office software type, the corresponding adjusting mode based on the color parameters can be selected for brightness adjustment; when the application type is determined to be a non-office software type application, a non-color parameter adjustment mode may be selected for brightness adjustment, such as a conventional ambient brightness based adjustment mode or a manual adjustment mode.
Step S403, respectively performing brightness adjustment on each light-emitting unit in each display area based on the target brightness parameter corresponding to each display area of the display interface in the adjustment mode.
In the specific implementation process of the step, after the adjustment mode based on the color parameters is determined, the brightness adjustment method in the embodiment of the invention can be adopted to adjust the brightness, namely, the color of each light-emitting unit is analyzed to obtain the color parameters; and adjusting the brightness of each light-emitting unit in response to the color parameter meeting a first condition.
