The color point is located on the upper or lower side of the axis of abscissa, and the proportion of green light is reduced, that is, the G value is reduced, so that the color point is purple due to the lack of green light. The color point is positioned on the right side of the center point, the blue proportion is reduced, namely the B value is reduced, and the display is yellow due to the lack of blue light; this design ensures all possible desired color effects and also avoids simultaneous RGB reduction, resulting in non-convergence of the effect.

In this embodiment, an example is provided in which the R value in the target RGB value is adjusted, if the abscissa value in the coordinate values is less than 0, the color point is determined to be on the left side of the center point of the color frame, and at this time, the corresponding percentage of the coordinate values may be obtained, and the R value of the target RGB value in the display characteristic curve is adjusted according to the percentage pair. For example, when the coordinate value is (-0.5, 0), the corresponding percentage of the coordinate value is obtained to be 5%, and then all R values in the target RGB values in the display characteristic curve are reduced by 5%. The corresponding relation between the coordinate value and the percentage can be stored in a coordinate value and percentage relation table, and the coordinate value and percentage relation table can be preset and written into a display.

The curve generating device 510 is preferably an industrial computer at the factory end, and can run a calibration program and perform corresponding data processing.
When necessary, the method for generating the display characteristic curve is performed by a curve generating device, and the display characteristic curve of the display to be corrected is generated before the display leaves the factory.
As shown in fig. 4, the method for generating a display characteristic curve of a display to be corrected by using the curve generating device provided by the embodiment of the application mainly includes the following steps:
s401, the curve generating device determines corresponding color information of the display under the selected tone sampling graphic card, wherein the color information is XYZ tristimulus values.
In the present embodiment, the tone chart card, XYZ tristimulus values, and chromaticity xy and luminance values Lv are different methods for representing colors in the image field. Further, the tone scale map card is generally represented by RGB values, which include three values, namely, R value, G value, and B value. The R value, G value, and B value may be the same value or different values. The color information is XYZ tristimulus values. Nine values are included in the XYZ tristimulus values, namely RX value, RY value, RZ value, GX value, GY value, GZ value, BX value, BY value and BZ value. The RX value, RY value, RZ value, GX value, GY value, GZ value, BX value, BY value and BZ value may be the same or different. Each color level sampling graphic card corresponds to different colors.
Further, in this embodiment, determining color information corresponding to the selected tone scale sampling chart on the display to be corrected includes: the curve generating equipment sequentially sends a color level sampling graphic card with a selected order to the display; the curve generating equipment sequentially acquires color ternary values corresponding to the tone-scale sampling graphic cards through a detection probe, wherein the color ternary values are chromaticity binary values xy and brightness values Lv; if the color triplet value meets the correction condition, the curve generating device determines color information corresponding to each tone scale sampling graphic card according to each color triplet and a color conversion formula; otherwise, determining the display to be corrected as a fault display.
