The display method of the application interface may be applied to the mobile terminal 110 shown in fig. 1, and the mobile terminal 110 may include a first display screen and a second display screen. The first display screen and the second display screen are oppositely arranged on two sides of the mobile terminal, the first display screen can be a color display screen, and the second display screen can be a black-and-white ink screen. As shown in fig. 2, the method may include:

Step 201, loading a first theme file.

In the embodiment of the application, the mobile terminal can be pre-stored with the first theme file. When the mobile terminal displays the application interface through the first display screen, the prestored first theme file can be loaded. The first theme file may include a first display element in the application interface and a color value of the first display element.

Step 202, displaying an application interface on a first display screen according to the first theme file.

After loading the first theme file, the mobile terminal may display the application interface on the first display screen according to the first theme file, where the color of the first display element on the application interface displayed on the first display screen may be a color. For example, the first display element may be blue in color.

Step 203, loading a second theme file.

In the embodiment of the application, the mobile terminal can also be pre-stored with a second theme file. The second theme file may include a second display element on the application interface and a gray value of the second display element. The second display element is the same as the first display element in content. And, each of the first display element and the second display element includes at least one of text and a picture.

If the second display element includes a picture, the picture included in the second theme file is a gray scale. If the second display element includes a text, the second theme file includes a gray value of the text.

And 204, displaying an application interface on a second display screen according to the second theme file.

After loading the second theme file, the mobile terminal can display an application interface on the second display screen according to the second theme file.

In summary, the embodiment of the application provides a display method of an application interface, where the display method of the application interface may display the application interface on a first display screen according to a loaded first theme file, and display the application interface on a second display screen according to a loaded second theme file. The application interfaces can be displayed by loading different theme files for different display screen mobile terminals, so that the definition of the application interfaces displayed by the black-and-white ink screen is improved, and the display effect of the application interfaces displayed by the black-and-white ink screen is further improved.

Fig. 3 is a flowchart of another method for displaying an application interface according to an embodiment of the present application. The display method of the application interface may be applied to the mobile terminal 110 shown in fig. 1, and the mobile terminal 110 may include a first display screen and a second display screen. The first display screen and the second display screen are disposed on two opposite sides of the mobile terminal 110, and the first display screen may be a color display screen, and the second display screen may be a black-and-white ink screen. As shown in fig. 3, the method may include:

Step 301, a first identifier is generated in response to a power-on instruction or a first switching instruction.

In the embodiment of the present application, the first identifier is used to indicate that the theme file to be loaded is a first theme file. Since the mobile terminal is usually defaulted to display the application interface on the first display screen after being powered on. The mobile terminal may generate the first identification in response to a power-on instruction. Or, the mobile terminal may generate the first identifier according to the received first switching instruction. The first switching instruction is used for indicating that the display screen in the display state is switched from the second display screen to the first display screen. By way of example, the first flag may be normal (normal).

In the embodiment of the application, the mobile terminal is provided with a startup key. After detecting the pressing operation of the user on the start key, the mobile terminal can generate a start instruction, and can respond to the start instruction to generate a first identifier.

Alternatively, a screen switch button may be provided on a navigation bar of the mobile terminal. When the mobile terminal displays the application interface through the second display screen, if the clicking operation of the user on the screen switching button is detected, a first switching instruction can be generated, and a first identifier can be generated in response to the first switching instruction.

Step 302, obtaining the identification of the theme attribute.

The mobile terminal may have stored therein an identification of the subject matter attribute. After generating the first identifier, the mobile terminal may acquire an identifier of the stored theme attribute, where the identifier of the theme attribute may be used to indicate that the currently loaded theme file is the first theme file or the second theme file. The identification of the subject matter attribute may be an identification of a last stored subject matter attribute prior to generating the first identification.

Alternatively, the identification of the theme attribute may be the first identification or the second identification. The first identifier may be normal and the second identifier may be electronic ink (eink). The theme property may also be referred to as a user interface mode (user interface mode).

Step 303, if the first identifier is different from the identifier of the theme attribute, updating the identifier of the theme attribute to the first identifier.

After the mobile terminal obtains the identifier of the theme attribute, it may detect whether the identifier of the theme attribute is the same as the first identifier, and if the identifier of the theme attribute is different from the first identifier, it indicates that the display screen currently in the display state is the first display screen, then the mobile terminal may update the identifier of the theme attribute to the first identifier, store the identifier of the theme attribute, and execute step 304. If the identification of the theme attribute is the same as the first identification, the display screen in the current display state is the second display screen, so that the mobile terminal can keep the identification of the theme attribute unchanged.

For example, if the first identifier is normal and the identifier of the theme attribute is eink, the mobile terminal may update the identifier of the theme attribute to normal and store the identifier of the theme attribute normal because the identifier of the theme attribute is different from the first identifier normal. If the first identifier is normal and the identifier of the theme attribute is normal, the mobile terminal may keep the identifier of the theme attribute unchanged because the identifier of the theme attribute is the same as the first identifier normal.

Step 304, loading the first theme file according to the identification of the theme attribute.

In the embodiment of the application, the mobile terminal is pre-stored with the first theme file and the corresponding relation between the mark of the theme attribute and the theme file. After updating the identifier of the theme attribute to the first identifier, the mobile terminal may determine a first theme file from the correspondence according to the identifier of the theme attribute, and load the first theme file. The first theme file may include a first display element in the application interface and a color value of the first display element. The first display element may include at least one of text and pictures.

For example, if the correspondence is shown in table 1, if the identifier of the theme attribute is normal, the mobile terminal may determine, from table 1, that the theme file corresponding to the identifier normal of the theme attribute is the first theme file according to the identifier normal of the theme attribute, and then the mobile terminal may load the first theme file.

TABLE 1

Identification of topic attributes	Theme file
		normal	First theme file
eink	Second theme file

Optionally, if the first display element includes a picture, the name of the first theme file may be a drawable (drapable), the first theme file may include the picture, and the picture may be a color picture. If the first display element includes text, the name of the first theme file may be a value (value), and the first theme file may include a color value of the text, for example, the color value may be a Red Green Blue (RGB) color value. If the first display element includes a picture and a text, the first theme file may include a color value and a picture of the text, and the picture may be a color picture. For example, the colors of the picture and text may both be blue.

Step 305, displaying an application interface on a first display screen according to the first theme file.

After loading the first theme file, the mobile terminal can display the application interface on the first display screen according to the first theme file, wherein the color of the first display element on the application interface displayed on the first display screen is color.

For example, if the first display element includes a picture and a text, and the first theme file includes a color value of the text and the picture, the mobile terminal may display the picture and the text in the application interface on the first display screen according to the color value of the text and the picture.

In the embodiment of the application, the mobile terminal detects whether the mark of the theme attribute is the same as the first mark, and updates the mark of the theme attribute to the first mark when the mark of the theme attribute is determined to be different from the first mark, so that the display screen in the display state is ensured to be actually switched from the second display screen to the first display screen, and the reliability of loading the first theme file is improved.

Step 306, in response to the second switching instruction, generates a second identifier.

The second identifier is used for indicating that the theme file to be loaded is a second theme file. And the mobile terminal can generate a second switching instruction if detecting the click operation of the user on the screen switching button in the process of displaying the application interface on the first display screen according to the first theme file, and can generate a second identifier in response to the second switching instruction.

The second switching instruction is used for indicating the display screen of the mobile terminal to be switched from the first display screen to the second display screen.

Step 307, obtain the identification of the theme attribute.

The mobile terminal stores the identification of the theme attribute. After the mobile terminal generates the second identifier, the identifier of the stored theme attribute may be obtained. The identity of the subject matter attribute is the identity of the last stored subject matter attribute before the second identity is generated. I.e. the identity of the subject matter attribute is the identity updated in step 303. By way of example, the identification of the subject property may be normal.

Step 308, if the second identifier is different from the identifier of the theme attribute, updating the identifier of the theme attribute to the second identifier.

After acquiring the identifier of the theme attribute, the mobile terminal may detect whether the identifier of the theme attribute is the same as the second identifier. If the identifier of the theme attribute is different from the second identifier, which indicates that the display screen currently in the display state is the second display screen, the mobile terminal may update the identifier of the theme attribute to the second identifier, store the identifier of the theme attribute, and execute step 309. If the identification of the theme attribute is the same as the second identification, the display screen in the current display state is the first display screen, so that the mobile terminal can keep the identification of the theme attribute unchanged. I.e. the mobile terminal still displays the application interface on the first display screen according to the first theme file.

For example, if the second identifier is a rink and the identifier of the theme attribute is a normal, the mobile terminal may update the identifier of the theme attribute to be a rink and store the identifier of the theme attribute in the rink because the identifier of the theme attribute is different from the second identifier rink.

Step 309, loading a second theme file according to the identification of the theme attribute.

In the embodiment of the application, the mobile terminal is pre-stored with the second theme file. After updating the identifier of the theme attribute to the second identifier, the mobile terminal may determine, according to the identifier of the theme attribute, a second theme file from the correspondence between the identifier of the theme attribute and the theme file, and load the second theme file.

The second theme file comprises a second display element in the application interface and gray values of the second display element. The second display element is the same as the first display element in content, i.e., the second display element is the same as the first display element in other properties except for color. And, each of the first display element and the second display element includes at least one of text and a picture. For example, if the second display element includes a picture, the picture included in the second theme file is a gray scale. If the second display element includes a text, the second theme file includes a gray value of the text.

For example, if the first display element and the second display element both include elliptical pictures, the two elliptical pictures are different in color, but identical in shape and size. If the second display element and the first display element both include the text "stop", the colors of the two text are different, but the font and the font size are identical.

For example, if the identifier of the theme attribute is a henk, the mobile terminal may determine, according to the identifier of the theme attribute, from table 1, that the theme file corresponding to the identifier of the theme attribute is a second theme file, and may load the second theme file.

Optionally, if the second display element includes a picture, the name of the second theme file may be drapable-sink, and the second theme file may include the picture, where the picture is a gray scale. If the second display element includes text, the name of the first theme file may be value, and the second theme file may include a gray value of the text. If the second display element includes a picture and a text, the second theme file may include a gray value and a picture of the text, and the picture is a gray image.

Optionally, if the first display element includes a first picture, the second display element includes a second picture, and contents of the first picture and the second picture are the same. The gray value of each pixel in the second picture in the second theme file may be determined based on the gray value of the pixel at the same position in the first picture in the first theme file. And if the gray value of a certain pixel in the first picture in the first theme file is within the first gray value range, the gray value of a pixel in the second picture in the second theme file at the same position may be the gray lower limit value. If the gray value of a certain pixel in the first picture in the first theme file is within the second gray value range, the gray value of a pixel in the second picture in the second theme file at the same position may be the gray upper limit value.

Wherein the upper limit of the first gray value range may be smaller than the lower limit of the second gray value range. For example, the first gray value range may be [0, 122], and the gray lower limit value may be 0. The second gray value range may be [123, 255], and the gray upper limit value may be 255.

If the first display element comprises a first text, the second display element comprises a second text, and the contents of the first text and the second text are the same. The gray value of the second text in the second theme file may be determined according to the gray value corresponding to the color value of the first text in the first theme file. If the gray value corresponding to the color value of the first text in the first theme file is within the first gray value range, the gray value of the second text in the second theme file may be a gray lower limit value. If the gray value corresponding to the color value of the first text in the first theme file is within the second gray value range, the gray value of the second text in the second theme file may be the gray upper limit value.

The contrast between the color of the second display element and the background image of the application interface displaying the second display element is increased by the method, so that the definition of the second display element displayed on the second display screen is higher than that of the first display element displayed on the second display screen, the definition of the second display element displayed on the application interface displayed on the second display screen is improved, and the display effect of the application interface displayed on the black-white ink screen is improved.

And 310, displaying an application interface on a second display screen according to the second theme file.

After loading the second theme file, the mobile terminal can display the application interface on the second display screen according to the second theme file.

For example, if the second display element includes a picture and a text, and the second theme file includes the picture and the text, the mobile terminal may display the picture and the text in the application interface on the second display screen according to the gray value of the text and the picture.

In the embodiment of the present application, taking the application interface as a call setting interface as an example, fig. 4 is a schematic diagram of a call setting interface displayed on a black-and-white ink screen according to the related art. As shown in fig. 4, the call setting interface may include a picture 00 and a picture 01, where the colors of the picture 00 and the picture 01 displayed in the black-and-white ink screen are gray.

Fig. 5 is a schematic diagram of a call setup interface displayed in a black-and-white ink screen according to an embodiment of the present application, where the call setup interface may be displayed by the black-and-white ink screen based on a second theme file loaded by a processor. The second theme file includes a second display element on the call setting interface, where the second display element may include a picture 05 and a picture 06, the picture 05 and the picture 06 are gray-scale images, and gray values of all pixels in the two gray-scale images may be 0. Therefore, as shown in fig. 5, in the call setup interface displayed on the black-and-white ink screen, the colors of the picture 05 and the picture 06 are black.

As can be seen by comparing fig. 4 and fig. 5, since the colors of the picture 05 and the picture 06 in the call setting interface shown in fig. 5 are black, the contrast between the colors of the two pictures and the background color of the call setting interface is larger, and the definition of the picture 05 and the picture 06 displayed in the whole call setting interface is higher.

If the application interface is an application information interface, fig. 6 is a schematic diagram of an application information interface displayed on a black-and-white ink screen in the related art. As shown in fig. 6, the application information interface may include the following first display elements: picture 00, two pictures 02, the text "deactivate" and the text "forced deactivate". Wherein the text "forced stop" is displayed on one picture 02 and the text "deactivated" is displayed on the other picture 02. The color displayed in the black-and-white ink screen for the picture 00, the two pictures 02, the text "deactivate" and the text "force deactivate" is gray.

Fig. 7 is a schematic diagram of an application information interface displayed in a black-and-white ink screen according to an embodiment of the present application. As shown in fig. 7, the application information interface may be displayed by a black and white ink screen based on the second theme file loaded by the processor. The second theme file may include a second display element on the application information interface that may include picture 05, two pictures 07, the text "deactivate" and the text "force stop". The picture 05 and the two pictures 07 are gray level images, the gray level value of all pixel points in each gray level image is 0, and the gray level values of the word "stop" and the word "forced stop" are both 0. Thus, as shown in fig. 7, in the application information interface displayed on the black-and-white ink screen, the colors of the picture 05, the two pictures 07, the text "stop" and the text "forced stop" are all black.

As can be seen from comparing fig. 6 and fig. 7, since the colors of the picture 05, the two pictures 07, the word "stop" and the word "forced stop" in the application information interface shown in fig. 7 are all black, the contrast ratio between the colors of the three pictures and the two words and the background color of the application information interface is larger, and the definition of the picture 05, the two pictures 07, the word "stop" and the word "forced stop" displayed in the whole application information interface is higher.

If the application interface is a contact selection interface, fig. 8 is a schematic diagram of a contact selection interface displayed on a black-and-white ink screen in the related art. As shown in fig. 8, the contact selection interface may include the text "cancel," the text "full select," and three pictures 04. The text "cancel", the text "select all", and the color displayed by the three pictures 04 in the black-and-white ink screen are all gray.

Fig. 9 is a schematic diagram of a contact selection interface displayed on an electronic ink display screen according to an embodiment of the present application. As shown in fig. 9, the contact selection interface may be displayed by a black and white ink screen based on the second theme file loaded by the processor. The second theme file may include a second display element on the contact selection interface that may include three pictures 09, the text "cancel" and the text "full select". The three pictures 09 are gray level diagrams, the gray level values of all pixels in the gray level diagrams are 0, and the gray level values of the words "cancel" and the words "select completely" are all 0. Thus, as shown in fig. 9, in the contact selection interface displayed on the black-and-white ink screen, the colors of the three pictures 09, the text "cancel" and the text "select all" are black.
