As shown in fig. 5, the display control method includes:

s501: and acquiring initial color information of the display screen.

S502: an initial occupancy value of the target type of light in the initial color information is determined.

S503: and determining a first initial node color and a second initial node color from the plurality of initial node colors, wherein the initial duty ratio of the first initial node color is larger than a duty ratio threshold value, and the initial duty ratio of the second initial node color is smaller than or equal to the duty ratio threshold value.

The descriptions of S501-S503 may be specifically referred to the above embodiments, and are not repeated herein.

S504: and determining a target duty ratio according to the initial duty ratio.

The ratio of the energy of the target type light ray which is preset and can enable the color display effect to reach the standard to the total energy of the spectrum can be called a target ratio, and the target ratio can be used as an index reference when the initial ratio is adjusted.

For example, the duty ratio threshold value 50% may be selected as the target duty ratio, 40% may be selected as the target duty ratio according to actual situations, and half of the numerical value 30% may be selected as the target duty ratio according to the initial duty ratio 60%.

S505: converting the first initial node color from the initial color space to the first color space to obtain the node color to be adjusted.

The RGB color space generated by overlapping the three basic colors of R (Red), G (Green), and B (Blue) to different degrees may be referred to as an initial color space, a first initial node color corresponds to the initial color space, a color-opposite (Lab) space generated based on luminance (L), a color-opposite dimension (representing a component a from Green to Red, and a component B from Blue to yellow) may be referred to as a first color space, the first color space may be used to adjust basic data such as luminance in the initial node color, a node color of the first color space generated by converting the first initial node color from the initial color space to the first color space may be referred to as a node color to be adjusted, and a display effect of the display screen may be controlled by adjusting a value of L, A, B in the node color to be adjusted.

In the embodiment of the disclosure, the first initial node color may be transferred from the RGB color space to the LAB color space, and the node color to be adjusted is obtained through conversion, and in the first color space, the node color to be adjusted is adjusted by adjusting the brightness (L) of the node color to be adjusted, the values of the component (a) representing the color from green to red, the component (B) representing the color from blue to yellow, and the like, which may be seen in the subsequent embodiment.

S506: an initial adjustment value of a target color dimension corresponding to a node color to be adjusted is determined, wherein the target color dimension is a color dimension in a first color space.

The value to be adjusted for the node color may be referred to as an initial adjustment value, where the initial adjustment value is a value of a target color dimension, and the color dimension corresponding to the first color space may be referred to as a target color dimension, where the target color dimension may be a luminance (L) dimension, a color dimension corresponding to a component (a) representing green to red, and a color dimension corresponding to a component (B) representing blue to yellow, when the first color space is a LAB color space, without limitation.

In the embodiment of the disclosure, the color dimension is adjusted to generate a corresponding initial adjustment value, which may be that a value in a specific target color dimension is selected as a reference value (L, A, B reference value) according to actual requirements, and the initial adjustment value is obtained according to a difference between the mapped value of the first color space and a preset reference value, or a specific initial adjustment value for reference is set, and the mapped value of the first color space is uniformly adjusted, or a color dimension to be adjusted is selected according to a characteristic of the first initial node color before color space conversion, and the corresponding initial adjustment value is determined, which is not limited.

For example, a high blue color node is transferred from an RGB color space to an LAB color space, and the B value is adjusted according to the characteristic of yellow or blue shift of the blue component B dimension control in the LAB space, so as to obtain an initial adjustment value to be adjusted.

S507: and performing calibration processing on the initial adjustment value according to the tone constraint condition to obtain a target adjustment value as adjustment information.

The preset condition of restricting the color tone of the node to be adjusted may be referred to as a tone restriction condition, where the tone restriction condition may be a threshold value of restricting the duty ratio of the target type light of the specific wavelength, or may also be information of restricting the overall brightness, contrast ratio, and the like of the display screen, which is not limited.

And checking whether the initial adjustment value meets the tone constraint condition, if so, the initial adjustment value meeting the tone constraint condition can be called a target adjustment value, and if not, the initial adjustment value can be selected to be subjected to calibration until the tone constraint condition is met, and the calibrated adjustment value is taken as the target adjustment value.

In the embodiment of the disclosure, the initial adjustment value is calibrated according to the tone constraint condition, which may be that the tone constraint condition is preset, the initial occupation ratio is calibrated until the tone constraint condition is met, or that a space vector three-dimensional map of the first color space is built, and the tone constraint condition is used as a constraint line or a constraint range in the space vector three-dimensional map, so as to adjust the initial adjustment value, or any other possible implementation manner is used, which is not limited.

Optionally, determining that the first initial node color maps to an initial hue value in a second color space, the first color space and the second color space being different; after the first initial node color is pre-adjusted based on the initial adjustment value is determined, the obtained adjusted node color is mapped to a target tone value in a second color space; if the change degree between the target tone value and the initial tone value is larger than the tone change threshold value, performing calibration processing on the initial adjustment value to obtain a target adjustment value; if the change degree between the target tone value and the initial tone value is smaller than or equal to the tone change threshold value, the initial adjustment value is used as the target adjustment value, the effect of adjustment processing can be enhanced due to the fact that the second color space is used for carrying out pre-adjustment on the first initial node color, the influence of tone factors on the color display effect is effectively reduced, and the accuracy of color adjustment can be improved due to the fact that the tone change threshold value is used as the basis of calibration processing carried out by the initial adjustment value.

The (Hue Saturation Value, HSV) space consisting of hue, saturation, and brightness may be referred to as a second color space in which hue (H), saturation (S), and brightness (V) may be adjusted as numerical values.

Wherein the tone value of the first initial node color mapping into the second color space may be referred to as an initial tone value and the generated adjusted tone value may be referred to as a target tone value.

The threshold value of the degree of change between the target tone value and the initial tone value, which is set in advance, may be referred to as a tone change threshold value, and the tone change threshold value may be used as a basis for determining whether to continue the calibration process of the initial adjustment value.

In the embodiment of the disclosure, the first initial node color may be mapped to the second color space, so as to obtain a hue (H), saturation (S), brightness (V) and other values of the first initial node color corresponding to the second color space, and adjust the hue, saturation, brightness and other values, so as to obtain the target adjustment value.

In the embodiment of the disclosure, whether the initial adjustment value needs to be calibrated or not can be judged according to the tone change threshold, if the change degree between the target tone value and the initial tone value is greater than the tone change threshold, the difference between the target tone value and the initial tone value can be obvious, and then the initial adjustment value can be calibrated or fine-adjusted to obtain the target adjustment value; if the degree of change between the target tone value and the initial tone value is less than or equal to the tone change threshold value, it may be indicated that the difference between the target tone value and the initial tone value is not significant, and the initial adjustment value may be regarded as the target adjustment value.

For example, the initial node color of Gao Languang is transferred from the RGB color space to the LAB color space, the B value is adjusted according to the characteristic of yellow or blue color control of the B dimension in the LAB space, then the change of the hue H before and after adjustment is judged to be obvious under the HSV space, if the change of the hue H before and after adjustment is too large, the adjustment amplitude of the B under the LAB space is reduced, if the change of the hue H before and after adjustment is tiny, the hue H is transferred back to the RGB color space again, so that the prediction model judges whether the target occupancy value can be reached, and if the target occupancy value is not reached, the B value can be adjusted under the LAB space continuously.

S508: and adjusting the first initial node color according to the adjustment information to obtain a first target node color, wherein the duty ratio of the target type light rays in the first target node color is a target duty ratio.

In the embodiment of the disclosure, according to adjustment information corresponding to a target adjustment value, the first initial node color is adjusted to generate a target node color, the adjustment information may be information of hue, space dimension, contrast, and the like, and by adjusting the first initial node color, a duty ratio of a target type light ray in the first target node color may be determined, and the duty ratio may be smaller than or equal to a duty ratio threshold value by using the duty ratio as the target duty ratio.

S509: and generating a target display lookup table according to the first target node color and the second initial node color.

The description of S509 may be specifically referred to the above embodiments, and will not be repeated here.

In this embodiment, since the initial occupancy rate of the target type light in the initial color information is determined, and the initial display lookup table is optimized in an auxiliary manner according to the initial occupancy rate, so as to obtain the target display lookup table, the target display lookup table can be used for performing display control, so that the color effect of the display screen can be effectively optimized, distortion phenomena in different color modes can be reduced, and the reduction degree of the display color of the display screen can be effectively improved. The method comprises the steps of obtaining initial color information of a display screen, determining an initial ratio of target type light rays in the initial color information, determining a first initial node color and a second initial node color from a plurality of initial node colors, determining the target ratio according to the initial ratio, converting the first initial node color from an initial color space to a first color space to obtain node colors to be adjusted, determining an initial adjustment value of a target color dimension corresponding to the node colors to be adjusted, wherein the target color dimension is the color dimension in the first color space, performing calibration processing on the initial adjustment value according to a tone constraint condition to obtain the target adjustment value as adjustment information, adjusting the first initial node color according to the adjustment information to obtain the first target node color, and generating a target display lookup table according to the first target node color and the second initial node color.
