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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

In order to solve the problem that the OLED screen has low brightness and low gray scale and is obvious in color unevenness or local brightness and darkness unevenness, a DeMura algorithm is mostly adopted in the related technology for processing. Specifically, the brightness information of each pixel point of the OLED screen under different gray scales is determined through the ultra-high-definition camera, and then the problems of color unevenness and brightness unevenness of the screen are optimized by adjusting the brightness degree of each sub-pixel. The DeMura algorithm is typically implemented in the driver chip (DDIC) of the screen. However, because the ultra-high-definition camera has limited light sensing capability and low brightness signal-to-noise ratio, the brightness information of the screen cannot be accurately calibrated; and because the storage space of the DDIC is limited, the brightness information of the screen can not be actually acquired under each gray scale of each brightness of the OLED screen. In addition, because the DeMura algorithm is implemented in the driving chip of the screen, the related compensation data are set, and when color unevenness or brightness unevenness still occurs, the user cannot adjust the display state of the screen by himself.
Based on the reasons, the problems of color unevenness and brightness unevenness still exist in the OLED screen in actual use, and under the condition of low brightness, the problems are more obvious, and the user experience is poor.
The utility model provides a show adjustment method, be applied to the terminal, in this method, when the display state of screen can't satisfy user's demand (for example there is uneven color or uneven bright dark phenomenon), through the DeMura compensation data in the current regulation information regulation terminal, form regional update compensation data, according to the regional display state of updating compensation data adjustment corresponding region, in order to realize the effect of the display state of regulation screen, solve the uneven color or uneven bright dark display problem of screen, especially improve the display effect of screen under the low luminance, thereby can satisfy user's demand better, promote the use and experience.
In one exemplary embodiment, a display adjustment method is provided. Referring to fig. 1, the method includes:
s110, determining current adjusting information; the current adjusting information comprises area adjusting data and display adjusting data, and the area adjusting data is used for representing the position of an area to be adjusted of the screen.
The current adjustment information may be determined by the user inputting corresponding information, for example, setting a corresponding application program in the terminal, or setting a corresponding adjustment interface (for example, an API interface for inputting the current adjustment information) through which the user inputs the current adjustment information.
In one embodiment, when the user finds that the brightness of the area A of the screen is darker than that of the other areas, a control instruction is input to the terminal, and a corresponding application program of the terminal is called. Then, the user inputs touch information in the form of a closed curve through the application program, wherein the closed area encloses the area a. And the terminal determines area adjustment data for representing the area A according to the touch information in the form of the closed curve. Through the application program, a user inputs the touch information of sliding up and down in the area A, and the terminal adjusts the brightness of the area A based on the received touch information of sliding up and down.
In one embodiment, when the user finds that the brightness of the area A of the screen is darker than that of the other area, a control command is input to the terminal, and an adjusting interface of the terminal is called. Then, the user inputs touch information in a closed curve form through the adjusting interface, wherein the closed area encloses the area A. And the terminal determines area adjustment data for representing the area A according to the touch information in the form of the closed curve. Through the adjusting interface, a user inputs the touch information sliding up and down in the area A, and the terminal adjusts the brightness of the area A based on the received touch information sliding up and down.
And S120, determining DeMura compensation data.
The DeMura compensation data is pre-stored data, and the pre-stored data is determined by a DeMura algorithm. That is, the DeMura compensation data refers to pre-stored compensation data that determines the terminal according to the DeMura algorithm, and the compensation data is used for compensating the display parameters of the screen and adjusting the display state. For example, DeMura compensation data is pre-stored in the driver chip.
The term Mura originates from japan, originally meaning uneven brightness, and then extends to any color difference on the panel that is recognizable to the human eye. For panel factories, quality monitoring is needed, so technicians detect and judge Mura on production lines, but the method is subjective, and judgment of different people is different, so that great trouble is brought to quality control. Therefore, the skilled person develops an aoi (automatic optical inspection) device to detect Mura, and performs compensation to eliminate Mura after detecting Mura, i.e. a DeMura algorithm.
At present, the DeMura algorithm of the OLED screen is integrated in a Driver IC (Driver chip) of the screen, and the specific algorithm is introduced as follows:
1. in a laboratory, measuring the brightness data of each pixel point of j gray scales of an i-piece screen by a high-precision camera, and comparing the brightness data with the gray scale-brightness data (or the gray scale-brightness data of a central pixel point) calculated theoretically to obtain j gray scale data groups with different brightness;
2. drawing a curve with an abscissa as a gray scale and an ordinate as brightness difference according to the gray scale data set, and then obtaining a relation between the gray scale and compensation through fitting, wherein the relation is used for converting the brightness difference of different gray scales;
3. and selecting the gray scale data group of a certain gray scale as data written into the driving chip.
4. Establishing a 2D brightness compensation gain lookup table aiming at different brightness and different gray scales (wherein different screens generally have different 2D brightness compensation gain lookup tables); the compensation gain lookup table includes the corresponding relationship between gray levels and brightness, for example, the table has gray levels in the horizontal direction and brightness in the vertical direction. In general, the format of the compensation gain lookup table in the driver chip is 5 × 5, which is optimized in a nonlinear space.
5. Under different DBVs (brightness control), the compensation data of the screen are determined by writing the gray scale data group of the driving chip and the compensation gain lookup table.
It should be noted that the above is only a brief introduction to the DeMura algorithm, and the detailed method can be determined by referring to the prior art.
In this step, the DeMura compensation data may be the compensation data determined in the step 5, or may be the gray scale data group written into the driver chip in the step 3 and/or the compensation gain lookup table in the step 4.
S130, adjusting the DeMura compensation data according to the current adjusting information, and determining the area updating compensation data of the area to be adjusted.
After the current adjusting information and the DeMura compensation data are determined, the DeMura compensation data are adjusted through the display adjusting data in the current adjusting information, the region to be adjusted is determined through the region adjusting data, and finally the region updating compensation data of the region to be adjusted are determined so as to adjust the original DeMura compensation data and further adjust the display state of the screen.
And S140, updating the compensation data according to the area, and adjusting the display state of the screen.
In this embodiment, the execution sequence of steps S110 and S120 may be interchanged, that is, the DeMura compensation data may be determined first, and then the current adjustment information may be determined.
According to the method, DeMura compensation data are adjusted through display adjustment data in current adjustment information, the area to be adjusted is determined through the area adjustment data, and then the area update compensation data of the area to be adjusted are determined, so that the display adjustment is carried out on the area to be adjusted, and the purpose of adjusting the screen display state is achieved.
For example, when the display of screen has the phenomenon of uneven color or uneven brightness, through the DeMura compensation data in the current regulation information regulation terminal, form regional update compensation data, adjust the display state in corresponding region according to regional update compensation data, in order to realize the effect of adjusting the display state of screen, solve the uneven color or uneven brightness's of screen display problem, especially improve the display effect of screen under low luminance, thereby can satisfy user's demand better, promote and use experience.
In one exemplary embodiment, a display adjustment method is provided, which is an improvement of step S130 in the above-described method. Referring to fig. 2, specifically, adjusting the DeMura compensation data according to the current adjustment information, and determining the area update compensation data of the area to be adjusted includes:
s210, adjusting DeMura compensation data according to the display adjustment data, and determining and updating the compensation data; wherein, the updated compensation data refers to the data of the DeMura compensation data after being adjusted by the display adjustment data;
and S220, determining data corresponding to the area to be adjusted in the updated compensation data according to the area adjustment data, and using the data as the area updated compensation data.
According to the method, firstly, DeMura compensation data are adjusted through display adjustment data in current adjustment information, the adjusted data are determined to be updated compensation data, then, data corresponding to a region to be adjusted in the updated compensation data are determined according to region adjustment data in the current adjustment information, and the data are used as region updated compensation data and used for adjusting the display state of a screen.
It should be noted that, data corresponding to the region to be adjusted in the DeMura compensation data may also be determined according to the region adjustment data, and then the region DeMura compensation data is adjusted by displaying the adjustment data, and the adjusted data is used as the region update compensation data to adjust the display state of the screen.
Referring to fig. 3, the specific steps are as follows:
s21, determining data corresponding to the region to be adjusted in the DeMura compensation data according to the region adjustment data, and taking the data as region DeMura compensation data;
s22, adjusting the DeMura compensation data of the area according to the display adjustment data, and determining area update compensation data; wherein, the region update compensation data refers to the data of the region DeMura compensation data after being adjusted by the display adjustment data.
In the method, the DeMura compensation data is screened through the area adjustment data in the current adjustment information, and then the screened area DeMura compensation data is adjusted through the display adjustment data in the current adjustment information, so that the data volume during data adjustment is reduced, the resource occupation of the method on the terminal can be reduced to a certain extent, and the efficiency of the method and the operation effect of the terminal are improved.
In one exemplary embodiment, a display adjustment method is provided, which is an improvement of step S130 in the above-described method. Specifically, in the method, the DeMura compensation data includes an original gray scale data set and an original compensation gain lookup table, the original gray scale data set is a gray scale data set written in the drive chip in the DeMura algorithm, and the original compensation gain lookup table is a compensation gain lookup table determined in the DeMura algorithm. The display adjustment data includes first sub-display adjustment data, which refers to data used to adjust the original compensation gain look-up table. The current adjustment information further comprises gray scale data corresponding to the current display state of the screen, wherein the gray scale data is used for representing a gray scale corresponding to the current display state of the screen.
It should be noted that the display state of the screen at a certain time can only correspond to a certain gray scale, and therefore, when the display state of the screen needs to be adjusted, only the compensation data corresponding to the corresponding gray scale needs to be determined.
In general, the terminal may determine the gray scale corresponding to the current display state according to the current display state, and the specific determination method may be directly implemented by the prior art, which is not described herein. In the method, the gray scale data may be data determined by the terminal itself, or may be input through a corresponding adjustment interface or a corresponding application program after the user reads the gray scale of the current display state determined by the terminal.
In the method, referring to fig. 4, adjusting the DeMura compensation data according to the current adjustment information, and determining the area update compensation data of the area to be adjusted includes:
s310, determining data to be adjusted in the original compensation gain lookup table according to the gray scale data.
And determining the gray scale corresponding to the current display state according to the gray scale data, then determining the data corresponding to the gray scale in the original compensation gain lookup table, and determining the data as the data to be adjusted.
As shown in fig. 5, for example, the Gray level corresponding to the Gray level data is Gray1, and the determined data to be adjusted is the data corresponding to Gray1 in the original compensation gain table.
As shown in fig. 5, for example, the Gray level corresponding to the Gray level data is Gray3, and the determined data to be adjusted is the data corresponding to Gray3 in the original compensation gain table.
And S320, adjusting the data to be adjusted according to the first sub-display adjustment data, and determining the adjusted data.
When the display state needs to be adjusted by adjusting the data in the original compensation gain lookup table, that is, when the display adjustment data is adjusted by the data of the compensation gain lookup table type, the data in the original compensation gain lookup table can be adjusted by the first sub-display adjustment data to determine the adjusted data.
In one embodiment, as shown in fig. 5, the original compensation gain lookup table includes a first sub-display adjustment data for adjusting all data of a row corresponding to DBV1 in the original compensation gain lookup table by a, and the data to be adjusted is data of a column corresponding to Gray1 in the original compensation gain lookup table, so that if the data to be adjusted is adjusted according to the first sub-display adjustment data, the adjusted data is a1+ a for adjusting data a1 in the original compensation gain lookup table according to the first sub-display adjustment data.
S330, determining a target gray scale data set according to the gray scale data and the original gray scale data set.
The gray scale corresponding to the current display state can be determined according to the gray scale data, and then the target gray scale data set corresponding to the gray scale is determined according to the original gray scale data set.
The original gray scale data group refers to a gray scale data group written in a driving chip, and the original gray scale data group refers to a data group formed by a certain gray scale and the brightness data of each pixel point corresponding to the gray scale. The target gray scale data group refers to a data group formed by gray scale corresponding to the current display state and brightness data of each pixel point corresponding to the gray scale.
In the terminal, if the drive chip of the terminal can realize the compensation of the display data of the screen through the DeMura algorithm, the DeMura algorithm comprises a relation between the gray scale and the compensation, so that after the gray scale corresponding to the current display state is determined, the target gray scale data set corresponding to the gray scale can be determined according to the original gray scale data set and the DeMura algorithm.
For example, the Gray level corresponding to the current display state is Gray2, and the Gray level corresponding to the original Gray level data set is Gray1, so that the target Gray level data set corresponding to Gray2 can be determined according to the DeMura algorithm. Specifically, the detailed method for determining the target gray-scale data set according to the gray scale corresponding to the current display state can be implemented by referring to the prior art, and is not described herein again.

The target gray scale data group and the adjusted data are used for determining updating compensation data, and the area adjusting data is used for determining an area to be adjusted. The method for determining the updated compensation data according to the target gray-scale data group and the adjusted data group is similar to the method for determining the compensation data according to the gray-scale data group and the compensation gain lookup table in the DeMura algorithm, and is not repeated here.
In one embodiment, the updated compensation data is determined according to the target gray-scale data group and the adjusted data, and then the data belonging to the area to be adjusted in the updated compensation data is determined according to the updated compensation data and the area adjustment data, and is used as the area updated compensation data for adjusting the display state of the screen.
