detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Fig. 1 is a schematic flowchart of a method for display control of a display screen provided by an embodiment of the present invention, the method can be executed by a display control device of a display screen, wherein the device can be implemented by software and/or hardware, and generally can be integrated in a terminal . As shown in Figure 1, the method includes:

Step 101, acquiring the current brightness value of the display screen.

Exemplarily, the terminal in this embodiment may specifically be a mobile terminal such as a mobile phone, a smart watch, a tablet computer, and a personal digital assistant; it may also be other terminals such as a desktop computer.

In this embodiment, the brightness value can specifically be the brightness setting value used to represent the brightness in the terminal, such as 2047, 1023 and 6, etc.; the brightness value can also be a brightness ratio value, such as 100% (the maximum brightness supported by the display screen ), 75% and 0% (the minimum brightness supported by the display) and other values. The current brightness value is used to represent the brightness value reached by the display screen at the current moment.

Step 102: Determine the adjustment information of the target color corresponding to the current brightness value according to the preset correspondence relationship.

In this embodiment, the target color is specifically the color corresponding to the color cast phenomenon of the display screen known in advance. For example, if a reddish phenomenon occurs on the display screen, then the target color is red; if a bluish phenomenon occurs on the display screen, then the target color is blue. After knowing the specific color cast of the display screen, the target color can be set according to the color cast. Common color casts include reddish, bluish, greenish, and yellowish, so correspondingly, the target color in this embodiment can be red, blue, green, and yellow. It can be understood that the target color in this embodiment is not limited to the above-mentioned several colors.

Exemplarily, the color cast phenomenon of the display screen can be investigated in advance. After the target color is determined, according to the color cast degree of the display screen at different brightness values, the relevant parameters of the target color can be adjusted through experiments to weaken the color cast. The influence of the target color on the display effect. After adjusting to the ideal display effect, record the adjustment information of the adjusted related parameters, and establish the preset corresponding relationship between the adjusted information and the brightness value, and save the preset corresponding relationship. into the terminal. In this step, the preset corresponding relationship can be queried according to the current brightness value, so as to obtain the adjustment information of the target color corresponding to the current brightness value.

Further, this step may include: determining the brightness interval in which the current brightness value is located; determining the adjustment information of the target color corresponding to the brightness interval according to the preset correspondence relationship. Exemplarily, the brightness value of the display screen may be divided into intervals, and this embodiment does not specifically limit the number of divided intervals, which may be determined by adjustment accuracy. The advantage of the optimization here is that by pre-establishing the corresponding relationship between the brightness range and the adjustment information, multiple brightness values can correspond to the same adjustment information, reducing the amount of calculation and improving the execution efficiency of this embodiment.

Step 103: Carry out corresponding attenuation adjustments for the target colors in the content to be displayed according to the determined adjustment information.

Exemplarily, in this step, before displaying the content to be displayed on the display screen, the content to be displayed may be obtained first, and the target color therein may be weakened and adjusted according to the adjustment information to obtain new content to be displayed.

The inventors found that the degree of color cast of a display screen that produces color cast phenomenon is generally inversely proportional to the brightness of the display screen, that is, the lower the brightness of the display screen, the more severe the color cast. Therefore, preferably, in this embodiment, the adjustment range of the attenuation adjustment is inversely proportional to the brightness value of the display screen.

Step 104 , outputting the adjusted content to be displayed to a display screen for display.

Exemplarily, since the display screen itself has color cast factors that cause color cast, if the unadjusted content to be displayed is directly output to the display screen for display, a color cast phenomenon related to the target color will occur. However, in this embodiment, before the content to be displayed is displayed, the target color in the content to be displayed is first weakened, so that the color cast phenomenon caused by the display screen itself can be corrected, and the color cast factor and color weakening can be corrected. After the final content to be displayed is synthesized, the displayed content can be displayed normally on the display screen, thereby solving the problem of color cast of the display screen.

The display control method of the display screen provided by the embodiment of the present invention obtains the current brightness value of the display screen, determines the adjustment information corresponding to the current brightness value of the target color according to the preset corresponding relationship, and treats the displayed content according to the determined adjustment information. The corresponding attenuation adjustment is performed on the target color and output to the display screen for display. By adopting the above technical solution, the target color in the content to be displayed is weakened according to the current brightness of the display screen, so that the component of the target color in the content to be displayed is reduced, and the problem of the display screen is solved without increasing the hardware cost. Color cast problem.

Fig. 2 is a schematic flowchart of another display control method of a display screen provided by an embodiment of the present invention. This embodiment is optimized based on the above-mentioned embodiment. In this embodiment, the step "determine the target according to the preset corresponding relationship The adjustment information of the color corresponding to the current brightness value" is optimized as follows: when it is determined that the current brightness value is greater than the preset brightness threshold, determine the target color corresponding to the current brightness value according to the preset corresponding relationship. Regulatory information.

Correspondingly, the method of this embodiment includes the following steps:

Step 201, acquiring the current brightness value of the display screen.

Step 202 , judging whether the current brightness value is smaller than a preset brightness threshold, if yes, execute step 203 ; otherwise, execute step 206 .

The inventors found that when the brightness of the display screen exceeds a certain brightness value, the phenomenon of color cast generally does not occur. At this time, there is no need to adjust the color of the content to be displayed, and the related steps of determining the adjustment information are omitted, which can improve the display of the display screen. Timeliness. The preset brightness threshold in this embodiment may vary due to factors such as the material and manufacturing process of the display screen, and may be determined through experiments.

Step 203: Determine the adjustment information of the target color corresponding to the current brightness value according to the preset correspondence relationship.

Step 204: Carry out corresponding weakening adjustments for the target colors in the content to be displayed according to the determined adjustment information.

Step 205 , outputting the adjusted content to be displayed to a display screen for display.

Step 206, display the content to be displayed.

The display control method of the display screen provided by the embodiment of the present invention determines whether it is necessary to weaken and adjust the target color in the content to be displayed according to whether the current brightness value is less than the preset brightness threshold value, and can ensure the display screen on the basis of solving the color cast problem. Overall display timeliness.

Fig. 3 is a schematic flowchart of another display control method of a display screen provided by an embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, the adjustment information is optimized as the primary color component to be adjusted. Adjusting the coefficient, optimizing the step of "performing corresponding attenuation adjustment on the target color in the content to be displayed according to the determined adjustment information" is: performing corresponding attenuation adjustment on the primary color component to be adjusted in the display content according to the adjustment coefficient.

Correspondingly, the method of this embodiment includes the following steps:

Step 301. Obtain the current brightness value of the display screen.

Step 302: Determine the adjustment coefficient of the primary color component to be adjusted corresponding to the current brightness value of the target color according to the preset correspondence relationship.

Exemplarily, the primary color component to be adjusted may include at least one of a red component, a green component and a blue component in an RGB (Red, Green, Blue) color mode. The specific primary color components to be adjusted are determined by the target color. For example, if the target color is red, the base color components to be adjusted are red components; the target color is blue, then the base color components to be adjusted are red components; the target color is yellow, then the base color components to be adjusted are red components and green components. It can be understood that the embodiments of the present invention are not limited to the RGB color mode, and are also applicable to other color modes, such as the CMYK mode. The value of the primary color component can be used to represent the density of the basic color, so by adjusting the primary color component, the weakening of the target color can be achieved.

Step 303: Carry out corresponding attenuation adjustment on the primary color component to be adjusted in the display content according to the adjustment coefficient.

The value of the primary color component can be used to represent the density of the basic color, so by adjusting the primary color component, the weakening of the target color can be achieved.

Preferably, the adjustment coefficient in this embodiment is a color scale percentage, and the color scale percentage is less than 1.

Specifically, this step may include: obtaining the current color scale value of the primary color component to be adjusted in the content to be displayed; calculating the product of the current color scale value and the corresponding color scale percentage to obtain the target color scale value; The tone level value is adjusted to the target tone level value.

Taking the RGB color mode as an example, the color scale value of each primary color component ranges from 0 to 255. The larger the color scale value of a primary color component, the darker the corresponding color density and the more components it occupies. In this embodiment, the current color scale value of the primary color component to be adjusted in the content to be displayed is multiplied by a color scale percentage less than 1, so that the color scale value of the primary color component to be adjusted becomes smaller, and the concentration of the target color is reduced. The components in the content to be displayed are reduced, thereby achieving the purpose of weakening and adjusting the target color and improving the color cast phenomenon.

It can be understood that the adjustment coefficient may also be a color scale adjustment value. Correspondingly, this step may include: obtaining the current color scale value of the primary color component to be adjusted in the content to be displayed; calculating the difference between the current color scale value and the corresponding color scale adjustment value to obtain the target color scale value; The current color level value is adjusted to the target color level value.

In this embodiment, the specific numerical value of the color scale percentage or the color scale adjustment value is not limited, and may be determined by the specific color cast of the display screen.

Step 304 , outputting the adjusted content to be displayed to a display screen for display.

In the embodiment of the present invention, the weakening of the target color is realized by weakening and adjusting the primary color component corresponding to the target color in the display content. The algorithm is simple and effective, and the target color in the content to be displayed can be adjusted quickly and accurately. , effectively solve the problem of color cast.

Fig. 4 is a schematic flowchart of another method for display control of a display screen provided by an embodiment of the present invention. This embodiment is described by taking the solution to the reddish problem of a display screen as an example. As shown in Fig. 4 , the method includes:

Step 401. Obtain the current brightness value of the display screen, and determine the brightness interval in which the current brightness value is located.

Exemplarily, the brightness of the display screen is divided into four brightness intervals in advance, which are 0%-25%, 25%-50%, 50%-75% and 75%-100%. Among them, 100% corresponds to the brightness setting value of 2047, and 0% corresponds to the brightness setting value of 6.

Step 402: Determine the color scale percentage of the red component corresponding to the brightness interval according to the preset correspondence relationship.

Exemplarily, the preset corresponding relationship includes: 0%-25% corresponds to a color scale percentage of 97%, 25%-50% corresponds to a color scale percentage of 98%, and 50%-75% corresponds to a color scale percentage of 99% %, 75%-100% corresponds to a color scale percentage of 100% (that is, when the current brightness value is greater than or equal to 75%, the red component will not be adjusted).

Step 403, acquiring the current color scale value of the red component in the content to be displayed.

Wherein, the color scale value of the red component is the value of R in the RGB value.

Step 404: Calculate the product of the current color scale value and the corresponding color scale percentage to obtain the target color scale value.

Step 405, adjusting the current color scale value to the target color scale value.

It can be understood that, in specific implementation, the adjustment can be performed in units of pixels, that is, the current color scale value corresponding to each pixel in the content to be displayed needs to be adjusted to the target color scale value, so as to realize color correction of the overall displayed content.

Step 406: Output the adjusted content to be displayed to the display screen for display.

In order to describe the embodiment of the present invention in more detail, further description will be made below with reference to experimental data. In order to facilitate the test, the test is carried out when the display screen is completely white. The RGB values of the pixels at any two positions are the same, generally (255, 255, 255). When the brightness setting value of the display screen is 2047, the screen displays The white is recorded as the target white. As the brightness gradually decreases, the white displayed on the screen will gradually appear reddish. When measuring different brightness values through the instrument, the value of the color coordinates corresponding to the color displayed on the screen. Table 1 shows the relevant test data without reducing the red component of the displayed content, and Table 2 shows the relevant test data after reducing the red component of the displayed content. (x, y) represent color coordinates.

5 is a schematic diagram of color coordinate comparison provided by the embodiment of the present invention. The dots in the figure represent the color coordinate point without reducing the red component, "X" represents the color coordinate point of reducing the red component, and the triangle represents the target point (the brightness setting value is The color coordinate point corresponding to the target white color displayed at 2047), the string adjacent to each color coordinate point indicates its corresponding brightness setting value (the string containing only numbers is the brightness setting value in Table 1, the string Include the letter "R" and numbers in Table 2 for brightness settings). It can be seen from Figure 5, Table 1 and Table 2 that by reducing the red component in different brightness ranges, the color coordinates of the reddish white (the color coordinate point without reducing the red component) are approached to the color coordinates (target point) of the target white, The color coordinate points that reduce the red component are obtained, so that the reddish phenomenon can be improved when displayed on the display screen. In addition, when the red component of the displayed content is not reduced, the value of x ranges from 0.2982 to 0.3086, with a difference of 0.0104; after the red component of the displayed content is reduced, the value of x ranges from 0.2977 to 0.3018, with a difference of 0.0041. It can be seen that with the adjustment of the brightness, the change range of the color coordinates of the red component is greatly reduced compared with that before the reduction of the red component, so as to realize the correction of the reddish phenomenon, especially when the brightness is low, the correction effect is particularly obvious.

The display control method of the display screen provided by the embodiment of the present invention gradually reduces the color scale value of the red component in the content to be displayed as the brightness of the display screen decreases, so that the red component in the content to be displayed is reduced without increasing the hardware cost Solved the problem of red cast of the display in the case of .
