Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In the related art, the mobile terminal may draw a display object by using an antialiasing technique and display the display object after the drawing is completed. The color of the edge of the display object drawn by the anti-aliasing technology is a transition color with sequentially changed gray scales, so that the color transition of the edge of the display object is natural when the electronic ink screen displays the display object according to a higher gray scale number.

However, when the electronic ink screen displays the display object according to a lower gray scale number, the transition color of the edge of the display object cannot be displayed according to the original gray scale level. For example, if the color of the edge of the display object drawn by the antialiasing technique is a transition color in which 6 gray levels sequentially change, when the electronic ink screen displays the display object according to a two-level gray scale (i.e., the number of gray levels is 2), the edge of the display object can only display 2 different gray levels. Therefore, the edge of the display object has obvious saw teeth, and the display effect of the display object is poor.

For example, referring to fig. 1, fig. 1 is a schematic diagram of a display object drawn by a mobile terminal in the related art. As can be seen from fig. 1, a transition color a exists at the edge of the display object. Fig. 2 is a schematic diagram of a display object displayed by a low gray scale in an electronic ink screen in the related art. As is apparent from fig. 2, the edge of the display object has jaggies b, and the display effect of the display object is poor.

In the related art, it is common to prevent the edges of the display object displayed on the electronic ink panel from being jagged by prohibiting switching the number of gray levels of the electronic ink panel to the lowest number of gray levels. However, this approach may result in less display flexibility for the mobile terminal.

The embodiment of the application provides a display method of a display object of a mobile terminal, and the method can be applied to the mobile terminal. The mobile terminal may include an electronic ink screen, and the electronic ink screen may support at least two different gray scale levels. That is, the electronic ink screen supports displaying images in at least two different levels of gray scale.

The gray scale number of the electronic ink screen may refer to: the number of different levels of brightness that can be displayed by each pixel in the electronic ink screen. Therefore, the higher the gray scale number of the electronic ink screen is, the clearer the gradation of the image displayed by the electronic ink screen is, and the richer the display effect of the image is.

For example, if the current number of gray levels of the electronic ink screen is 16, each pixel point in the electronic ink screen can display 16 different levels of brightness. If the current gray level number of the electronic ink screen is 2, each pixel point in the electronic ink can display 2 different levels of brightness.

Optionally, the mobile terminal may be a mobile phone, a tablet computer, or a wearable device, for example, the mobile terminal may be a mobile phone. Moreover, the operating system of the mobile terminal may be an Android operating system (Android). Referring to fig. 3, the method may include:

and step 101, displaying the display object subjected to the anti-aliasing processing according to a first gray level number in a status bar of the electronic ink screen.

The mobile terminal can acquire the display object to be displayed after the antialiasing processing, and can display the display object after the antialiasing processing in a status bar of an electronic ink screen according to a first gray scale number.

Wherein the first number of gray levels may be greater than the number threshold. The number of levels threshold may be pre-stored in the mobile terminal.

Step 102, a selection operation for a second gray scale level of the at least two gray scale levels is received.

The mobile terminal may display at least two gray scale levels, and the user may select a second gray scale level of the at least two gray scale levels. Accordingly, the mobile terminal may receive a selection operation for a second gray scale level of the at least two gray scale levels.

And 103, if the second gray level is determined to be less than or equal to the level threshold, displaying the display object which is not subjected to anti-aliasing processing in the status bar of the electronic ink screen according to the second gray level.

The mobile terminal may detect whether the second gray scale level is greater than the level threshold after receiving a selection operation for the second gray scale level. If the mobile terminal determines that the second gray level is less than or equal to the level threshold, the display object without anti-aliasing processing can be displayed in the status bar of the electronic ink screen according to the second gray level.

Wherein the edges of the display object without the anti-aliasing process have no transition color. Therefore, when the display object which is not subjected to anti-aliasing processing is displayed on the electronic ink screen, the edge of the display object is smooth, the display object is clear, and the display effect is good.

In summary, the embodiment of the present application provides a display object display method of a mobile terminal, where after determining that a selected second gray scale is less than or equal to a threshold, the mobile terminal may display a display object that is not subjected to anti-aliasing processing in a status bar of an electronic ink screen according to the second gray scale. Compared with the display object which is displayed according to the second gray scale and subjected to anti-saw processing, the edge of the display object which is displayed according to the second gray scale and is not subjected to anti-saw processing is smooth, the edge of the display object is clear, and the display effect is good.

In addition, in the mobile terminal provided by the embodiment of the application, the electronic ink screen can display the display object according to a first gray level greater than the level threshold value and also according to a second gray level lower than the level threshold value, so that the display flexibility of the mobile terminal is effectively improved.

Fig. 4 is a flowchart of another display method for a display object of a mobile terminal according to an embodiment of the present application, where the method may be applied to a mobile terminal. The mobile terminal may include an electronic ink screen, and the electronic ink screen may support at least two different gray scale levels. Optionally, the operating system of the mobile terminal may be an Android operating system (Android). Referring to fig. 2, the method may include:

step 201, displaying the display object after the anti-aliasing treatment according to a first gray level number in a status bar of the electronic ink screen.

The first number of gray levels may be greater than the threshold number of levels, for example, the first number of gray levels may be the largest number of gray levels of at least two gray levels supported by the electronic ink screen. The number of steps threshold may be pre-stored in the mobile terminal, for example, the number of steps threshold may be 4.

Optionally, displaying the object may include: at least one of a text object and an icon object. For example, the display object may be a text image. The text image may be a number, such as a number indicating a time of the mobile terminal and a number indicating a remaining power of the mobile terminal.

Step 202, a selection operation for a second gray scale level of the at least two gray scale levels is received.

And the mobile terminal receives and responds to the gray level number adjusting instruction and displays at least two gray level number selection controls. Wherein, each gray level number selection control corresponds to a gray level number. The user can touch the gray level number selection control corresponding to the second gray level number in the at least two gray level number selection controls. Accordingly, the mobile terminal may receive a selection operation for the gray scale number selection control corresponding to the second gray scale number.

Optionally, the mobile terminal may be installed with a grayscale switching application of an electronic ink screen. The user can touch the application identifier of the gray scale switching application, and correspondingly, the mobile terminal can receive a gray scale adjustment instruction and can display at least two gray scale selection controls in response to the gray scale adjustment instruction.

Optionally, the at least two gray scale number selection controls may correspond to at least two gray scale numbers one to one. Or, a plurality of gray level number selection controls in the at least two gray level number selection controls correspond to the same gray level number. The gray scale number selection controls corresponding to the same gray scale number can be in one-to-one correspondence with multiple refreshing modes of the electronic ink screen under the gray scale number.

Optionally, the grayscale selection control may be an on-off control.

For example, referring to fig. 5, assuming that the electronic ink screen supports only two gray scale numbers, 16 and 2, respectively, the application of the gray scale number switching application is identified as the application icon. In the case that the number of gray levels is 2, the electronic ink screen of the mobile terminal supports multiple refresh modes, for example, three different refresh modes, such as an equalization mode, a smooth mode, and a fast mode, are supported. The refresh frequency of the electronic ink screen in the three refresh modes is different, and the refresh frequency of the electronic ink screen in the rapid mode is higher than that of the electronic ink screen in the smooth mode. The refreshing frequency of the electronic ink screen in the fluency mode is higher than that of the electronic ink screen in the balance mode.

Assuming that the gray level number selection control is an on-off control, as shown in fig. 5, an application identifier 011 of the gray level number switching application is displayed in a navigation bar 01 of the mobile terminal, and a user touches the application identifier 011. Accordingly, the mobile terminal may display a first switch control 012, a second switch control 013, a third switch control 014, and a fourth switch control 015. The number of gray levels corresponding to the first switch control 012 is 16, and the number of gray levels corresponding to the second switch control 013 through the fourth switch control 015 are all 2. The refresh mode corresponding to the second switch control 013 is the leveling mode, the refresh mode corresponding to the third switch control 014 is the smooth mode, and the refresh mode corresponding to the fourth switch control 015 is the fast mode.

Assuming that the current gray scale number of the electronic ink screen of the mobile terminal is 16, a first switch control 012 (i.e., a switch control corresponding to the gray scale number 16) in four switch controls displayed by the mobile terminal may be in a disabled state, that is, the mobile terminal may not respond to a touch operation performed by a user on the first switch control 012. As can be seen from fig. 5, the switch control in the disabled state (e.g., the first switch control 012) has a different display effect than the switch control in the off state (e.g., the second switch control 013). For example, as shown in fig. 5, the color of the switch control in the disabled state may be gray, and the color of the switch control in the off state may be white.

As shown in fig. 5, the user touches the fourth switch control 015, and accordingly, the mobile terminal may receive a selection operation for the second gray scale level 2 in response to the touch operation of the user for the fourth switch control 015. With continued reference to fig. 5, the display effect of the on-state switch control (e.g., the fourth switch control 015) may be different from the display effect of the off-state switch control and the display effect of the off-state switch control. For example, the color of the on-off control in the on state is black.

Moreover, after the mobile terminal subsequently adjusts the gray scale of the electronic ink screen to the gray scale corresponding to the fourth switch control 015, the mobile terminal may further update the states and display effects of the first switch control 012 and the fourth switch control 015 to prompt the user of the current gray scale of the electronic ink screen. For example, the mobile terminal may update the state of the first switch control 012 from the disabled state to the off state and adjust its color from gray to white, and may update the state of the fourth switch control 015 from the on state to the disabled state and adjust the color of the fourth switch control 015 from black to gray.

Step 203, detecting whether the second gray scale number is greater than a number threshold.

The mobile terminal may detect whether a second gray scale number of the at least two gray scale numbers is greater than the number threshold after receiving a selection operation for the second gray scale number. If the mobile terminal determines that the second gray scale level is greater than the level threshold, the following step 204 may be performed. If the mobile terminal determines that the second gray scale level is less than or equal to the level threshold, step 205 described below may be performed.

In this embodiment of the present application, an application framework (freamwork) layer may be run in the mobile terminal. After receiving the selection operation for the second gray scale number of the at least two gray scale numbers, the gray scale number switching application may determine the second gray scale number, and may call an Application Program Interface (API), and report the second gray scale number to the application program framework layer. Accordingly, the application framework layer may obtain the second gray scale level.

The application framework layer may then compare the second gray scale level to a level threshold. If the application framework layer determines that the second gray scale level is greater than the level threshold, then step 204 may be performed. If the application framework layer determines that the second gray scale level is less than or equal to the level threshold, step 205 may be performed.

For example, assuming that the number of levels threshold is 4, if the second gray level number determined by the mobile terminal is 8, since 8 is greater than 4, the mobile terminal may determine that the second gray level number is greater than the number of levels threshold, and then may perform step 204. If the second gray scale number determined by the mobile terminal is 2, since 2 is less than 4, the mobile terminal may determine that the second gray scale number is less than the number threshold, and then may execute step 205.

And 204, if the second gray level is determined to be greater than the level threshold, displaying the display object subjected to anti-aliasing processing in the status bar of the electronic ink screen according to the second gray level.

And after the mobile terminal determines that the second gray level is greater than the level threshold, the display object subjected to anti-aliasing processing can be displayed in the status bar of the electronic ink screen according to the second gray level. That is, after determining that the second gray scale level is greater than the level threshold, the mobile terminal only needs to control the electronic ink screen to switch the gray scale level.

In this embodiment, if the application framework layer of the mobile terminal determines that the second gray scale level is greater than the level threshold, a first switching instruction may be sent to the electronic ink screen of the mobile terminal, where the first switching instruction carries the second gray scale level. After receiving the first switching instruction, the electronic ink screen may switch the current first gray scale number to the second gray scale number in response to the first switching instruction. Therefore, the mobile terminal can display the display objects subjected to the anti-aliasing processing according to the second gray level number in the status bar of the electronic ink screen.

And step 205, displaying the display objects which are not subjected to the anti-aliasing processing in the status bar of the electronic ink screen according to the second gray level.

The mobile terminal may display the display object that is not anti-aliased in accordance with the second gray scale number in the status bar of the electronic ink screen when it is determined that the second gray scale number is less than or equal to the number threshold.

If the application program framework of the mobile terminal determines that the second gray scale number is less than or equal to the number threshold, a first switching instruction carrying the second gray scale number may be sent to the electronic ink screen, so that the electronic ink screen can switch the current first gray scale number to the second gray scale number. The application framework layer sends the first gray level switching instruction to the electronic ink screen, so that the process of switching the number of gray levels of the electronic ink screen may refer to the related implementation process in step 204, which is not described herein again in this embodiment of the present application.

In this embodiment, a system user interface (systemuui) process and a drawing process may also be run in the mobile terminal. Based on this, the process of the mobile terminal displaying the display object which is not anti-aliased in the status bar of the electronic ink screen according to the second gray scale level may include:

after determining that the second gray level number is less than or equal to the number threshold, the application framework layer may close the antialiasing processing function of the rendering process and send an update instruction to the SystemUI process. After receiving the update instruction, the systemin process may invoke a rendering process in response to the update instruction to obtain the display object that is not antialiased, thereby controlling the electronic ink screen to display the display object that is not antialiased in its status bar according to a second gray scale level.

After determining that the second gray level is less than or equal to the level threshold, the application framework layer may close the antialiasing processing function of the rendering process and may notify the systemou process to refresh the display object in the status bar. Therefore, the display object which is displayed in the previous status bar and is subjected to anti-aliasing processing can be updated to the display object which is not subjected to anti-aliasing processing, namely, the display object with the transition color at the edge is updated to the display object without the transition color at the edge, so that the problem that the edge of the display object has the aliasing due to the transition color at the edge of the display object can be effectively solved when the electronic ink screen displays according to the second gray scale, the edge of the display object is smooth and clear, the display effect of the display object is ensured, and the user experience of a user of the mobile terminal is effectively improved.

Optionally, before the mobile terminal leaves the factory, a developer may add an enable flag bit of the antialiasing function to the mobile terminal, so that the application framework layer can enable or close the antialiasing processing function of the rendering process by setting a flag value of the enable flag bit. And when the mobile terminal displays the display object after the anti-aliasing processing in the status bar, the flag value of the enabled flag bit is a default value, and the default value is the enabled anti-aliasing function used for indicating the drawing process.

Based thereon, the application framework layer may set the flag value of the enable flag bit to a target value upon determining that the second gray scale level is less than or equal to the level threshold. Wherein the target value may be used to indicate that the antialiasing function of the rendering process is to be turned off. The target value is different from the default value, for example, the target value is 1 and the default value is 0.

Optionally, the application framework layer can send the update instruction to the systemuui process in a broadcast manner. For example, the systemin ui process may register a broadcast listener for listening for update instructions to update the display objects in the status bar. If the application framework layer determines that the second gray level is less than the level threshold, it may be determined that the display object in the status bar needs to be updated, and then an update instruction for updating the display object may be broadcast, where the update instruction carries a refresh parameter for instructing a systemuui process to forcibly refresh the display object in the status bar. Accordingly, the SystemUI process can receive the update instruction through the broadcast listener.

In this embodiment, after receiving the update instruction, the systemin process invokes the rendering process to obtain the display object that is not processed by antialiasing, which may include:

because the update instruction carries the refresh parameter, after receiving the update instruction, the systemin process can acquire the resource file of the display object to be displayed from the kernel of the mobile terminal and directly transmit the resource file to the Activity process of the mobile terminal. The Activity process may then pass the resource file to a native layer through the View process. The native framework layer can call a painting brush (paint) and a canvas (canvas) in the drawing process through an on draw method. The marker value of the enabled marker bit can be read by the brush, and the anti-aliasing function can be closed after the brush reads the target value because the current marker value of the marker bit is the target value, so that the display object which is not subjected to anti-aliasing processing can be obtained based on the resource file.

For a scene in which the display object includes a text object and an icon object, the systemuui process may traverse a plurality of controls in the status bar, and for each traversed control, the systemuui process may acquire a resource file corresponding to the control.

For a scene in which the display object is a text object, the systemuui process may only obtain resource files corresponding to the time control and resource files corresponding to the electric quantity control in the status bar. Therefore, the mobile terminal can be prevented from consuming more resources.

For example, FIG. 6 is a schematic diagram of a display object displayed by an electronic ink screen in a second gray scale level below a level threshold in the related art. Fig. 7 is a schematic diagram of a display object displayed by an electronic ink screen according to a second gray scale level lower than a level threshold according to an embodiment of the present disclosure.

In fig. 6, an image c is a partially enlarged schematic view of the display object in the status bar, and it can be seen from fig. 6 that there is a significant jaggy at the edge of the display object in the related art, and the display effect of the display object is poor.

In fig. 7, an image d is a partially enlarged schematic view of a display object in the status bar. Comparing the image c with the image d, it can be seen that the jaggy of the edge of the display object displayed by the method provided by the embodiment of the application is obviously improved, the edge of the display object is smoother, and the display effect is better.

In the embodiment of the present application, after the mobile terminal displays the display object without anti-aliasing processing in the status bar of the electronic ink screen according to the second gray scale number, if a selection operation for a third gray scale number of the at least two gray scale numbers is received and it is determined that the third gray scale number is less than the threshold of the number of levels, the mobile terminal may display the display object without anti-aliasing processing according to the third gray scale number.

Optionally, after determining that the third number of gray levels is smaller than the number threshold, the application framework layer of the mobile terminal may send a second switching instruction to the electronic ink screen of the mobile terminal, where the second switching instruction carries the third number of gray levels. The electronic ink screen may switch the current second gray scale level to a third gray scale level in response to the second switching command.

For example, suppose the number of gray levels supported by the electronic ink screen is 16,8,4 and 2, respectively, and the threshold of the number of levels is 4. The mobile terminal displays the anti-aliasing processed display object according to 16-level gray scale, and then receives a selection operation for a second gray scale level 4. Since the second gray level number 4 is equal to the level number threshold 4, the mobile terminal may display the display objects that are not anti-aliased in 4 levels of gray in the status bar of its electronic ink screen. Thereafter, the mobile terminal receives a selection operation for the third gray scale number 2, and since the third gray scale number 2 is less than the number threshold, the mobile terminal may display the display object without the anti-aliasing process in 2-level gray scale in a state of its electronic ink screen.

If the mobile terminal receives a selection operation for a third gray level of the at least two gray levels and determines that the third gray level is greater than the level threshold, the mobile terminal may display the anti-aliased display object according to the third gray level.

Optionally, after determining that the third gray level number is greater than the number threshold, the application framework layer of the mobile terminal may send a second switching instruction to the electronic ink screen, so that the electronic ink screen switches the current second gray level number to the number of the third gray level. And, the application framework layer can send update instructions to the SystemUI process and enable the antialiasing processing function of the drawing process. The systemin process may invoke the rendering process in response to the update instruction to obtain the antialiased display object, thereby controlling the electronic ink screen to display the antialiased display object in its status bar according to a third gray scale level.

For example, suppose the number of gray levels supported by the electronic ink screen is 16,8,4 and 2, respectively, and the threshold of the number of levels is 4. The mobile terminal displays the anti-aliasing processed display object according to 16-level gray scale, and then receives a selection operation for a second gray scale level 4. Since the second gradation level 4 is equal to the level threshold 4, the mobile terminal can display the display objects that are not anti-aliased in 4 gradations in the status bar of its electronic ink screen. Thereafter, the mobile terminal receives a selection operation for the third number of gray levels 8, and since the third number of gray levels 8 is greater than the number-of-levels threshold, the mobile terminal can display the anti-aliasing processed display object in 8-level gray levels in the state of its electronic ink screen.

It should be further noted that, the order of the steps of the image display method of the mobile terminal provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be correspondingly increased or decreased according to the situation. Those skilled in the art can easily conceive of various methods within the technical scope of the present disclosure, and therefore, the detailed description is omitted.
