Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In order to provide better user experience, the display parameters of the display screen can be adjusted according to the brightness of ambient light in the display process of the display screen at present, and the display brightness of the display screen is adjusted to be bright under the condition that the brightness value of the ambient light is larger by taking the automatic adjustment of the screen brightness as an example; and when the brightness value of the ambient light is smaller, the display brightness of the display screen is dimmed.
The premise for realizing accurate adjustment of the screen brightness is accurate detection of ambient light. In the related art, in order to accurately collect the brightness value of the ambient light, referring to fig. 1, an opening is required to be provided on the display screen 11 to accommodate the light sensor 12. However, the mode can affect the screen occupation ratio of the display screen and does not meet the requirement of the current full-screen.
Based on the above situation, an embodiment of the present disclosure provides a control method for a display screen, where at least two light sensors are arranged below a display module of the display screen, and a light brightness value of an environment where the display screen is located is determined by the at least two light sensors under the screen, so as to adjust a display parameter of the display screen according to the light brightness value.
It should be noted that, since the Light sensor is disposed below the display module, the display module is required to have a better Light transmittance, and the display module may be, but not limited to, an OLED (Organic Light-Emitting diode) display module.
Fig. 2 is a flowchart illustrating a control method of a display screen according to an embodiment of the present disclosure, which may include the steps of:
in step 202, each set of luminance data corresponding to each light sensor is obtained.
Each group of brightness data comprises a first brightness value obtained by detection of the corresponding light sensor and a second brightness value of a display area of the corresponding light sensor in the display module.
Fig. 3 is a schematic cross-sectional structure diagram of a partial structure of a display screen according to an embodiment of the present disclosure, in which two light sensors, namely, a light sensor a and a light sensor b, are taken as an example, and both of the light sensors are located below the display module 31. The number of the light sensors is not limited to 2 shown in the figure, and 3, 4 or even more light sensors can be arranged according to actual requirements.
The light sensors can be arranged at intervals, and/or the connecting line of each sensor is not parallel to the frame of the display screen, so that the brightness data of different display areas can be acquired. The light sensors may be of the same or different types, but the working principle of the light sensors is ensured to be consistent. If the models of the light sensors are different, the brightness data needs to be normalized before determining the voltage drop coefficient.
Each light sensor corresponds to a group of brightness data, and each group of brightness data comprises a first brightness value detected by the light sensor and a second brightness value corresponding to the display area.
Referring to fig. 3, for the light sensor a, the second luminance value may represent the display luminance of the display area a corresponding to the light sensor a in the display module, and the second luminance value of the display area a is related to the pixel value of the display content of the display area a and may be obtained by the display system. If the display area A comprises a plurality of pixel points, the brightness values of the pixel points in the display area A can be respectively obtained, and the brightness values of the pixel points are weighted and summed to obtain a second brightness value corresponding to the sensor a. Similarly, for the light sensor B, the second brightness value may represent the display brightness of the display area B corresponding to the light sensor B in the display module, and the second brightness value of the display area B is related to the pixel value of the display content of the display area B and may be obtained by the display system. If the display area B contains a plurality of pixel points, the luminance values of the pixel points in the display area B can be respectively obtained, and the luminance values of the pixel points are weighted and summed to obtain a second luminance value corresponding to the sensor B.
Since the light 32 received by the light sensor is the ambient light after penetrating through the display module, the voltage DROP (IR-DROP) of the display module will affect the light received by the light sensor. The voltage drop of the display module is that each pixel of the display module is connected with a power supply voltage, the power supply voltage supplies power to each pixel, and due to hardware factors of the display module, the difference of the display content of the whole display screen of the display screen can cause the power supply voltage of each pixel to not meet the requirement of the expected voltage, and the display brightness of the display screen is different due to the difference of the display content due to the fact that the power supply voltage is adjusted in a certain degree in an equal ratio. Therefore, even if different contents are displayed under the same ambient light, the display brightness of the display screen is different, and the brightness value detected by the light sensor is also different. Therefore, in the related art, the ambient brightness value is determined by a mode of determining the ambient brightness value from the brightness value detected by the light sensor to the screen display brightness value, and the ambient brightness value obtained by the calculation cannot accurately reflect the brightness value of the ambient light.
And step 204, determining a voltage drop coefficient of the display module according to each group of brightness data.
In the using process of the display screen, a partial area of the display screen is possibly shielded due to the reasons of holding by hand, a nearby obstacle and the like, if the shielded area is a display area corresponding to a partial light sensor, a first brightness value detected by the partial light sensor is smaller than a first brightness value detected by an unshielded light sensor, and brightness data corresponding to the shielded light sensor cannot accurately reflect the brightness value of ambient light, so that the brightness data need to be excluded before calculating the voltage drop coefficient. Specifically, referring to fig. 4, the method may include the following steps:
step 203-1, determining the maximum first brightness value of each group of brightness data.
If there is shielding in some light sensors, it can be understood that the maximum first brightness value is the first brightness value detected by the light sensor that is not shielded, and the shielded brightness data can be excluded by the maximum first brightness value.
Step 203-2, determine whether the number of groups of the luminance data having the difference between the first luminance value and the maximum first luminance value smaller than the difference threshold is greater than 1.
Wherein, the difference threshold value can be set according to the actual demand.
If the difference between the first brightness value and the maximum first brightness value in a set of brightness data is smaller than the difference threshold, it indicates that the first brightness value is close to the maximum first brightness value, and the corresponding light sensor is likely not shielded, the set of brightness data may be used to calculate the pressure drop coefficient.
If the difference between the first brightness value and the maximum first brightness value in a set of brightness data is not less than the difference threshold, it indicates that the first brightness value is greatly different from the maximum first brightness value, the corresponding light sensor is likely to be blocked, and the set of brightness data is not suitable for calculating the voltage drop coefficient and should be excluded.
If the number of the remaining groups of luminance data is greater than 1 after the blocked luminance data is excluded, that is, if more than 2 groups of luminance data remain, the voltage drop coefficient can be determined according to the more than 2 groups of luminance data, that is, the step of determining the voltage drop coefficient according to the luminance data is performed.
The following describes a specific implementation of determining the droop coefficient from more than 2 sets of brightness data.
Considering the influence of the voltage drop of the display module on the second brightness value of the display area, the formula for calculating the brightness value of the environment may be, but is not limited to, expressed as:
ambient brightness value detected by the light sensor-brightness value of the display area corresponding to the light sensor-voltage drop coefficient (1)
If 2 sets of luminance data remain after the luminance data elimination, taking 2 sets of luminance data corresponding to the light sensor a and the light sensor b shown in fig. 3 as an example, the two sets of luminance data can be represented as:
first brightness value detected by the light sensor a-second brightness value of the area a-pressure drop coefficient (2)
First brightness value detected by light sensor B-second brightness value of region B-pressure drop coefficient (3)
The first brightness value detected by the light sensor a, the first brightness value detected by the light sensor B, the second brightness value of the area a and the second brightness value of the area B are known quantities, and by combining the formulas (2) and (3), the following results are obtained:
thus, the pressure drop coefficient can be determined according to equation (4).
If more than 3 groups of brightness data remain after the brightness data elimination, the remaining more than 3 groups of brightness data can be fitted, and the pressure drop coefficient is determined according to the fitting result.
If the determination in step 203-2 is negative, that is, after the luminance data is eliminated, only one set of luminance data remains, and since the voltage drop coefficient cannot be calculated according to one set of luminance data, in one embodiment, the display parameters of the display screen may be adjusted according to the set of luminance data, specifically referring to step 203-3.
And 203-3, compensating the maximum first brightness value according to the second brightness value in the brightness data containing the maximum first brightness value, so as to adjust the display parameters of the display screen according to the compensated maximum first brightness value.
Step 203-3 may be based on the formula: the compensation to the maximum first brightness value is realized by the environment brightness value which is the brightness value detected by the light sensor-the brightness value of the display area, the environment brightness value which is the maximum first brightness value-the second brightness value is also the maximum first brightness value obtained after the compensation, and then the display parameters of the display screen can be adjusted according to the maximum first brightness value obtained after the compensation. For example, if the compensated maximum first brightness value falls within a first preset brightness range, adjusting the display parameters of the display screen according to preset display parameters corresponding to the first preset brightness range; and if the compensated maximum first brightness value falls into a second preset brightness range, adjusting the display parameters of the display screen according to preset display parameters corresponding to the second preset brightness range.
In another embodiment, if only one set of luminance data is left after the luminance data is eliminated, since the voltage drop coefficient cannot be calculated, the environmental parameter cannot be accurately determined, or no step may be performed until two sets of unshielded luminance data are detected, and then the voltage drop coefficient is calculated and the display parameter is adjusted.
If the determination in step 203-2 is yes, that is, the voltage drop coefficient can be calculated according to the plurality of sets of luminance data, step 206 is executed.
And step 206, compensating the first brightness value in the group of brightness data according to the voltage drop coefficient and the second brightness value in any group of brightness data, so as to adjust the display parameter of the display screen according to the compensated first brightness value.
After the voltage drop coefficient is determined, an environment brightness value can be determined according to the voltage drop coefficient and any group of brightness data, specifically, the voltage drop coefficient and a first brightness value and a second brightness value of any group of brightness data can be substituted into the formula (1), and an environment brightness value can be obtained, the environment brightness is also the compensated first brightness value, and then the display parameters of the display screen can be adjusted according to the compensated first brightness value. For example, if the compensated first brightness value falls within a first preset brightness range, adjusting the display parameters of the display screen according to preset display parameters corresponding to the first preset brightness range; and if the compensated first brightness value falls into a second preset brightness range, adjusting the display parameters of the display screen according to preset display parameters corresponding to the second preset brightness range.
Because the display parameter adjustment of the display screen is generally only performed when the automatic parameter adjustment function is started and the display screen is in a bright screen state, the brightness data can be acquired only when the automatic parameter adjustment function of the display screen is started and the display screen is in the bright screen state, and the steps of calculating the voltage drop coefficient and automatically adjusting the display parameters of the display screen are executed. And under the condition that the automatic adjusting function is not started or the display screen is in the screen-off state, any action of adjusting the display parameters is not executed, so that the power consumption of the system is saved.
In the embodiment of the disclosure, with the help of at least two optical line sensors, the display parameter of the display screen is automatically adjusted, because the optical line sensors are sensors under the screen, the screen occupation ratio of the display screen cannot be influenced, and the pressure drop coefficient of the display screen can be determined through the detection data of the at least two optical line sensors, so that the environment brightness value is accurately determined according to the pressure drop coefficient, the pressure drop influence of the display screen is eliminated, the display parameter is automatically adjusted, and the user experience is improved.
