Fig. 1 shows a method flow diagram of an adjustment method according to an embodiment of the application. As shown in fig. 1, the adjusting method for a display panel according to an embodiment of the present application includes the steps of:
in step S101, target brightness and target color coordinates of a target area on a display panel are acquired;
and acquiring target brightness and target color coordinates of a target area on the display panel. The display panel is, for example, a display panel (screen) of a television, a mobile phone, a smart watch, or the like. The target area is, for example, a panel portion to be subjected to adjustment, and may be the entire panel, a part of the panel, a certain pixel on the panel, or the like. The target luminance is, for example, the luminance of the display of the desired target area. The target color coordinates are, for example, colors (color coordinates) to be displayed in the target area.
Optionally, acquiring the target brightness and the target color coordinates of the target area includes: acquiring a reference gray-scale image of a target area (data information of the reference gray-scale image displayed by the target area); and obtaining target brightness and target color coordinates according to the reference gray-scale image.
In step S102, a measured luminance and a measured color coordinate of the target area are obtained;
the measured brightness and the measured color coordinates of the target area are acquired. For example, a camera is used to photograph the target area, and then the measured brightness and the measured color coordinates of the target area are obtained according to the photographed image. The brightness, for example, the brightness actually displayed by the reaction target area is measured. Color coordinates such as the color (color coordinates) actually displayed by the reaction target area are measured.
Optionally, acquiring the measured luminance and the measured color coordinates of the target area includes: displaying a reference gray scale image on a target area; measuring a target area displayed with a reference gray-scale image to obtain reference gray-scale image measurement data; and obtaining measurement brightness and measurement color coordinates according to the reference gray-scale image measurement data.
In step S103, converting the target brightness and the target color coordinates into standard target values according to the surface standard;
the target brightness and target color coordinates are converted into standard target values according to the surface standard. For example, the target brightness and the target color coordinates are calculated according to the surface standard, and the standard target value is obtained. The surface standard includes, for example, at least one selected from the CIE1931 chromaticity system, meng Saier chromaticity system, RGB chromaticity system, and the like.
In step S104, the measured brightness and the measured color coordinates are converted into standard measurement values according to the surface standard;
the measured brightness and the measured color coordinates are converted into standard measurement values according to the same surface standard. For example, the measurement luminance and the measurement color coordinates are calculated based on the same surface standard as in step S103, to obtain a standard measurement value.
In step S105, according to the deviation between the standard target value and the standard measurement value, the display parameter corresponding to the target area is adjusted.
And adjusting the display parameters corresponding to the target area according to the deviation between the standard target value and the standard measured value. The deviation between the standard target value and the standard measurement value is corrected, for example, by adjusting the display parameter of the target area so that the adjusted brightness and color coordinates of the display of the target area are the target brightness and target color coordinates. Optionally, according to the deviation between the standard target value and the standard measured value, the gray-scale gamma (gamma) curve corresponding to the target area and/or the parameter of the R register and/or the parameter of the G register and/or the parameter of the B register are adjusted.
In an alternative embodiment of the present application, the adjustment method for the display panel is specifically a general adjustment method (solution) applied to adjust the gray scale gamma curve in DGC (digtial gamma control, digital gamma control) (digital image gray scale control) mode.
Previously, the applicant adjusts the gray scale gamma curve by DGC to a predetermined color coordinate and brightness. The applicant found that the chip can only control the brightness of three colors by the values of the R (red), G (green) and B (blue) registers, but cannot determine the color coordinates and the brightness of the gray-scale image after the three colors are mixed, and it is difficult to qualitatively adjust the R, G, B registers, and only different R, G, B register combinations can be continuously tried to approach the target value, and the gamma adjustment needs a long time.
The surface standard includes, for example, the CIE1931 chromaticity standard (CIE 1931 chromaticity system). Of course, other types of surface markings may be included. Converting the target brightness and target color coordinates into standard target values according to the surface standard comprises: converting the brightness and color coordinates of the target into three-dimensional coordinates of the target; and converting the three-dimensional coordinate of the target into the RGB chromaticity coordinate of the target. Converting the measured luminance and the measured color coordinates into standard measurement values according to the surface standard comprises: converting the measured brightness and the measured color coordinates into measured three-dimensional coordinates; the measured three-dimensional coordinates are converted into measured RGB chromaticity coordinates. Specifically, luminance and color coordinates of a target (target luminance and target color coordinates) are converted into XYZ coordinates (target three-dimensional coordinates) and then into (target) RGB chromaticity coordinates by the CIE1931 chromaticity system. The target RGB chromaticity coordinates can be noted as TR, TG, and TB (standard target values). The measured luminance and color coordinates (measured luminance and measured color coordinates) are converted into XYZ coordinates (measured three-dimensional coordinates) and then into (measured) RGB chromaticity coordinates by the CIE1931 chromaticity system. The measured RGB chromaticity coordinates can be noted CR, CG and CB (standard measured value/current value).
Alternatively, the measurement data (measurement color coordinates and measurement luminance) are noted as x, y, L, i.e., measurement color coordinates x, measurement color coordinates y, and measurement luminance L. Converting the measurement data into XYZ coordinates, i.e. x=x/y×l; y=l; z= (1-x-y)/y. Converting the XYZ coordinates (measured three-dimensional coordinates) into measured RGB chromaticity coordinates includes performing an inverse matrix calculation on the measured three-dimensional coordinates to obtain measured RGB chromaticity coordinates. Optionally, the conversion is performed according to the CIE1931 standard chromaticity system, and the specific conversion relationship is:
the above describes a method of converting measured color coordinates and measured luminance. The same conversion method can be used to convert the target color coordinates and the target luminance.
In an alternative embodiment of the application, the adjustment method further comprises: and obtaining a target R chromaticity coordinate (TR), a target G chromaticity coordinate (TG) and a target B chromaticity coordinate (TB) according to the target RGB chromaticity coordinates. From the measured RGB chromaticity coordinates, a measured R chromaticity Coordinate (CR), a measured G chromaticity Coordinate (CG), and a measured B chromaticity Coordinate (CB) are obtained.
According to the deviation between the standard target value and the standard measured value, adjusting the display parameters corresponding to the target area comprises:
comparing the R chromaticity coordinate of the target with the R chromaticity coordinate of the measurement; when the R chromaticity coordinate of the target is larger than the R chromaticity coordinate, increasing a register value of an R register of a region corresponding to the R chromaticity coordinate; and when the R chromaticity coordinate of the target is smaller than the R chromaticity coordinate, reducing the register value of an R register of the region corresponding to the R chromaticity coordinate.
Comparing the G chromaticity coordinate of the target with the measured G chromaticity coordinate; when the G chromaticity coordinate of the target is larger than the G chromaticity coordinate, increasing a register value of a G register of a region corresponding to the G chromaticity coordinate; and when the G chromaticity coordinate of the target is smaller than the G chromaticity coordinate, reducing the register value of the G register of the region corresponding to the G chromaticity coordinate.
Comparing the target B chromaticity coordinate with the measured B chromaticity coordinate; when the target B chromaticity coordinate is larger than the measured B chromaticity coordinate, increasing a register value of a B register of a region corresponding to the measured B chromaticity coordinate; and when the target B chromaticity coordinate is smaller than the measured B chromaticity coordinate, reducing the register value of the R register of the region corresponding to the measured B chromaticity coordinate.
That is, comparing the three colors, respectively, determines how to adjust the chip R, G, B register:
red:
when cr=tr, the chip R register value is unchanged;
increasing the R register value of the chip when CR is smaller than TR;
when CR > TR, reduce the R register value of chip;
green:
when cg=tg, the chip G register value is unchanged;
when CG is smaller than TG, increasing the register value of the chip G;
when CG is larger than TG, reducing the register value of the chip G;
blue:
when cb=tb, the chip B register value is unchanged;
when CB is smaller than TB, increasing the register value of the chip B;
when CB > TB, the chip B register value is decremented.
