Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

It should be noted that when describing a specific embodiment, the sequence number of each process does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not be used in the implementation of the embodiment of the present invention. process constitutes any qualification.

FIG. 1 is a schematic flowchart of a display control method in an embodiment of the present invention. As shown in Figure 1, the method includes the following steps.

Step 101, acquire the first color gamut of target information.

The target information may be various types of information stored in the mobile terminal and displayed on the display screen of the mobile terminal, for example, various pictures or videos displayed in an album program or a gallery program installed on the mobile terminal.

The target information has a color gamut, and the color gamut to which the target information is mapped is acquired as the first color gamut. Optionally, as an example, taking the target information as an example, the image has a color profile (ICC file, ICC ColorProfile), and the color profile carries the color gamut to which the image is mapped, which can be directly obtained from the color profile Extract the color gamut to which this image is mapped. By extracting the color gamut from the color characteristic file, a large number of images can be preprocessed in the background, and then the color gamut can be adjusted in the background.

Step 102. Map the target information from the first color gamut to a second color gamut.

The second color gamut is preset and can be any standard color gamut or user-defined color gamut, only need to ensure that the second color gamut has fewer blue color gamut points than the first color gamut has blue color gamut Just click. Optionally, as an example, the first color gamut may be the sRGB color gamut, and the second color gamut may be the CMYK color gamut.

Optionally, as an example, after the first color gamut and the second color gamut are determined, the first conversion matrix of the first color gamut and the second color gamut can be established, and each pixel in the target information can be converted to Points are adjusted to the second color gamut. Regardless of the type of target information, it is only necessary to determine the first color gamut, the second color gamut, and the conversion matrix related to the first color gamut and the second color gamut, and the color gamut can be quickly adjusted for a large amount of target information of the same color gamut.

Taking the first color gamut as sRGB color gamut and the second color gamut as CMYK color gamut as an example, the conversion matrix from sRGB color gamut to CIEXYZ can be:

Subsequently, based on the above conversion matrix, the RGB information of each pixel in the target information can be converted into XYZ information, and the target information can be mapped to the CMYK color gamut.

Step 103, controlling the display screen to display the target information in the second color gamut.

Since the blue color gamut points of the second color gamut are less than the blue color gamut points of the first color gamut, when the display screen displays target information in the second color gamut, the number of blue organic light-emitting materials that are lit It will be relatively less, thereby reducing the usage rate of blue organic light-emitting materials, delaying the attenuation of blue organic light-emitting materials, and can improve the color cast and distortion caused by the fast decay of color organic light-emitting materials, thereby extending the display screen. service life.

Fig. 2 is a schematic flowchart of a display control method in another embodiment of the present invention. As shown in Figure 2, the method includes the following steps.

Step 201, acquire the first color gamut of target information.

Step 202. Map the target information from the first color gamut to a second color gamut.

For the above steps 201 and 202, reference may be made to the contents of steps 101 and 102 in the foregoing embodiments, and no further description is made here.

Step 203, establishing a second conversion matrix between the current color gamut of the display screen and a preset target color gamut.

The number of blue color gamut points in the target color gamut is less than the number of blue color gamut points in the current color gamut of the display screen. Optionally, as an example, the current color gamut of the display screen may be the sRGB color gamut, and the target color gamut may be CMYK color gamut.

Step 204, based on the second transformation matrix, map the target information from the second color gamut to a third color gamut.

Since the number of blue color gamut points in the target color gamut is less than the number of blue color gamut points in the current color gamut of the display screen, the number of blue color gamut points in the third color gamut obtained through the second conversion matrix is also less than that in the second color gamut Number of blue gamut points.

Step 205, controlling the display screen to display the target information in the third color gamut.

Since the third color gamut is obtained from the second color gamut based on the second conversion matrix, when the display screen displays the target information in the third color gamut through the current color gamut, it is equivalent to the display screen displaying the target in the second color gamut through the target color gamut Information, since the target color gamut has fewer blue color gamut points than the current color gamut, the blue color of the target information displayed on the display screen can be made lighter, and the usage rate of blue pixels can be further reduced. When the target color gamut and the second color gamut are both CMYK color gamuts, the display screen can be truly displayed according to the second color gamut.

Optionally, as an example, before step 205 is performed to display the target information, the color gamut of the display screen is adjusted to a preset standard color gamut, for example, sRGB. When step 203 is executed subsequently, the second conversion matrix formed by the sRGB color gamut and the CMYK color gamut can be directly invoked without further calculation of the second conversion matrix.

To sum up, by further adjusting the target information from the second color gamut to the third color gamut, and using the third color gamut with fewer blue gamut points, the problem of too many blue gamut points in the current color gamut of the display screen can be improved, so that The blue color of the target information displayed on the display screen is lighter, further reducing the usage rate of blue pixels.

Fig. 3 is a schematic flowchart of a display control method in another embodiment of the present invention. As shown in Figure 3, the method includes the following steps.

Step 301, acquiring the current running state and current color gamut of the display screen of the mobile terminal.

In the embodiment of the present invention, the current operating state of the display screen is used to describe the performance parameters of the content displayed on the display screen. Optionally, as an example, the current running state may include at least one of the following items: the type of the application program running on the display screen, the brightness of the display screen when displaying content, and the lighting duration of the display screen when displaying content.

Step 302 , when the current operating state and the current color gamut meet a preset condition, adjust the color gamut of the display screen.

In the embodiment of the present invention, there are various types of current operating states of the display screen, and various types of current color gamuts of the display screen. The two can be combined to form various embodiments, and the preset conditions for these embodiments are different. , and the corresponding strategies for adjusting the color gamut of the display screen are also different.

Optionally, as an example, the color gamut of the display screen can be artificially adjusted to a first color gamut or a second color gamut, the second color gamut has fewer blue gamut points than the first color gamut has blue color gamut points. For example, the first color gamut may be the sRGB color gamut, and the second color gamut may be the CMYK color gamut.

When the display screen displays content based on the second color gamut, the number of lit blue organic light-emitting materials will be relatively small, thereby reducing the usage rate of blue organic light-emitting materials, delaying the attenuation of blue organic light-emitting materials, and improving the The color shift and distortion caused by the fast decay of the color organic light-emitting material prolong the service life of the display.

The following lists different types of current running statuses and current color gamuts, and describes this step in detail.

Optionally, as an example, the current running state of the display screen includes the type of the application program running on the display screen, and step 302 may further include the following sub-step: the type of the application program running on the display screen is preset When the first type and the current color gamut of the display screen is the first color gamut, adjust the color gamut of the display screen to the second color gamut; the type of application running on the display screen is preset When the second type and the current color gamut of the display screen is the second color gamut, adjust the color gamut of the display screen to the first color gamut.

The application programs belonging to the first preset type do not have high requirements on the display quality of images, and even do not need to display images. At this time, adjusting the color gamut of the display screen to the second color gamut with fewer blue color gamut points will not reduce the user’s The visual experience can also reduce the usage rate of blue organic light-emitting materials and delay the attenuation of blue organic light-emitting materials. The application programs belonging to the first preset type may include at least one of the following: e-book application programs, song application programs, web page application programs, news application programs, payment application programs, and social networking application programs. The application programs belonging to the second preset type have higher requirements on the display quality of pictures, such as photo album programs, gallery programs, picture editing programs, etc. One color gamut can guarantee the user's visual experience.

Optionally, as yet another example, the current operating state of the display screen includes the brightness value of the display screen; step 302 may further include the following sub-step: when the brightness value of the display screen is lower than a preset brightness threshold and the When the current color gamut of the display screen is the first color gamut, adjust the color gamut of the display screen to the second color gamut; when the brightness value of the display screen exceeds the preset brightness threshold and the current color gamut of the display screen When it is the second color gamut, the color gamut of the display screen is adjusted to the first color gamut.

The preset brightness threshold can be set according to the color sensitivity of different regions and different races, and is determined by the threshold value of the human eye's sensitivity to color. When the brightness value of the display screen is low, the sensitivity of the human eye to color is low. Adjusting the color gamut of the display screen to the second color gamut with fewer blue color gamut points will not reduce the user's visual experience, and can also reduce blue color. The utilization rate of the blue organic light-emitting material is slowed down, and the decay of the blue organic light-emitting material is delayed. When the brightness is higher than the preset brightness threshold, human eyes are more sensitive to colors. At this time, adjusting the color gamut of the display screen to the first color gamut with more blue color gamut points can ensure the user's visual experience.

Optionally, as another example, the current operating state of the display screen includes the lighting duration of the display screen; step 302 may further include the following sub-step: when the lighting duration of the display screen exceeds the preset brightness threshold And when the current color gamut of the display screen is the first color gamut, adjust the color gamut of the display screen to the second color gamut; when the lighting duration of the display screen is zero and the off-screen duration exceeds the preset When the off-screen duration threshold is set and the current color gamut of the display screen is the second color gamut, the color gamut of the display screen is adjusted to the first color gamut.

The preset bright screen duration threshold can be set according to the duration of healthy eyes. If the lighting duration exceeds the preset duration, the color gamut of the display will be adjusted to the second color gamut with fewer blue color gamut points, reducing the amount of blue light. Therefore, eye diseases caused by blue light can be improved, and at the same time, the usage rate of blue organic light-emitting materials can be reduced, and the attenuation of blue organic light-emitting materials can be delayed. The off-screen time threshold is also set according to the reasonable rest time of the human eye. If the off-screen time exceeds the preset off-screen time, it is considered that the human eye has rested enough. At this time, the color gamut of the display is adjusted to the first blue color gamut point. One color gamut can guarantee the user's visual experience.

Step 303, controlling the display screen to display target information according to the adjusted color gamut.

To sum up, by selecting matching adjustment strategies to adjust the color gamut of the display screen according to different types of current operating statuses and current color gamuts, it is possible to improve the utilization rate of blue color gamut points and the user's visual experience, ensuring the display's service life.
