The user has a high requirement for color reduction of the display picture in the preset mode, and the user has a low requirement for color reduction of the display page in other situations, such as when displaying a menu page, and does not need to adjust the color parameters of the display picture, so that the white balance parameter adjustment is performed when the OLED screen is in the preset mode.
The gray scale is to divide the brightness change between the brightest and darkest into different levels, each level represents a brightness change, the more intermediate levels are, the finer and finer the displayed picture effect is, and the display picture can be converted into a gray scale picture according to the multi-level gray scale.
And when the OLED screen is in a preset mode, the OLED screen displays a gray scale picture. The image mode can be set to the movie mode by the professional through the HDMI (High Definition Multimedia Interface) or the video channel.

The OLED screen television displays a white balance correction menu, as shown in fig. 3, which displays a preset number of key frames, wherein the key frames are generated according to gray levels, for example, twenty gray levels are distinguished according to brightness variation between the brightest and the darkest, when the gray levels are 5%, 10%, etc. of the brightest brightness, 100%, and the key frames correspond to 5%, 10%, etc. of the brightest brightness, 100%. The user can switch the tuning points corresponding to the key frames left and right and set the color parameters corresponding to the tuning points. The red, green, and blue parameters may be adjusted separately under each key frame. Illustratively, the default gain values of the red parameter, the green parameter and the blue parameter are all 0, the adjustable range is-15 to 15, and the gain values of the red parameter, the green parameter and the blue parameter are set and stored independently and do not influence each other. The reset function of the white balance correction menu may restore the gain values of the red, green, and blue parameters at the selected tuning point to default values of 0 by one key.

Specifically, SDR (Standard Dynamic Range), and HDR (High Dynamic Range) are different sources. Compared with an SDR film source, the HDR film source has richer colors and clearer details, and can better represent gradual changes and levels of light and colors in an image. Taking a grayscale image as an example, dividing the SDR slice source into 256 parts from black to white and dividing the HDR slice source into 1024 parts, 3DLUT data needs to be generated for processing of the SDR slice source and the HDR slice source respectively.
And acquiring the color parameters of the gray-scale picture after the white balance parameters are adjusted, loading 3DLUT data corresponding to a preset standard dynamic range SDR chip source or loading 3DLUT data corresponding to a preset high dynamic range HDR chip source, and determining the color parameters of the gray-scale picture after the white balance parameters are adjusted in a preset color space. And 3DLUT data corresponding to the SDR film source or the HDR film source is determined by a preset color space. And converting the color space of the current gray scale picture into a preset color space through 3DLUT data corresponding to the SDR film source or the HDR film source, thereby adjusting the color parameters of the current OLED screen.
As shown in fig. 7, for SDR and HDR film sources, a.3 dl file may be imported in the factory menu for them, respectively; the 3D LUT function item is located in [ factory menu ]; entering a 3D LUT menu, and displaying four keys of an introduction SDR-3D LUT, a reset SDR-3D LUT, an introduction HDR-3D LUT and a reset HDR-3D LUT in the 3D LUT menu; the import key can read and import files named 3DLUT-SDR.3dl and 3DLUT-HDR.3dl in the U packing directory.
In the technical scheme of this embodiment, according to 3DLUT data corresponding to an SDR slice source or 3DLUT data corresponding to a preset HDR slice source with a high dynamic range, color parameters of a gray-scale picture after white balance parameter adjustment in a preset color space are determined, the gray-scale picture is converted into the preset color space, color restoration is achieved, and a lens with weakly changing colors is mapped to the preset color space with a wider color gamut, so that more accurate color parameters can be calibrated under the condition of richer color contrast.

Referring to fig. 8, fig. 8 is a fifth embodiment of the color adjustment method for an OLED panel according to the present invention, and based on the fourth embodiment, the step S100 includes:
step S101, determining a plurality of pixel nodes in a pixel range corresponding to the adjusted color parameters of the gray scale picture;
step S102, converting the color parameter of each pixel node into a color parameter of a preset color space corresponding to the 3DLUT data according to the 3DLUT data;
step S103, determining the color parameters of the gray-scale picture in a preset color space according to the converted color parameters of each pixel node.
Specifically, a plurality of pixel nodes are determined according to the pixel range corresponding to the color parameter of the adjusted gray-scale picture, for example, the color parameters include three channels R, G, and B, 17 pixel nodes may be adopted on each channel, 17 pixel nodes are taken at equal intervals on each channel, and the 3DLUT data has 17 × 17 — 4913 pixel nodes in total. And converting the color parameters of each pixel node into the color parameters of a preset color space corresponding to the 3DLUT data. For example, as shown in fig. 9, when the color parameter of a pixel point of the adjusted gray-scale picture is (50,50,50), the color parameter of the pixel point after the conversion to the preset color space is (70,70, 70); when the color parameter of the pixel point of the adjusted gray-scale picture is (50,70,50), the color parameter of the pixel point is (85,90,70) after the pixel point is converted into the preset color space; when the color parameter of the pixel point of the adjusted gray-scale picture is (50,70,60), the color parameter of the pixel point after the conversion to the preset color space is (90,95, 80).
And determining the color parameters of the gray-scale picture in a preset color space according to the converted color parameters of each pixel node. When non-pixel nodes other than the pixel node display color, the CalMAN software may be used to correct the color parameters at the non-pixel nodes. The CalMAN software has an accurate hardware shading algorithm,this is particularly true in the case of multiple screens. After generating 3D LUT data, the data is passed through DLCTM(dynamic linear correction algorithm) that adds correction data around the pixel nodes to adjust the color parameters at the non-pixel nodes while automatically optimizing the color parameters of the non-linear display. CalMAN software can also be adopted to respectively generate 3DLUT-SDR.3dl and 3DLUT-HDR.3dl files. The generated 3DLUT-SDR.3dl and 3DLUT-HDR.3dl files are copied to a U disk directory, then the U disk is mounted on the OLED television, and the two files are imported through a factory menu. In the factory menu, the menu is entered into the 3D LUT, and the menu of the 3D LUT displays the implementation of the menu of importing SDR-3D LUT and importing HDR-3D LUT.
