Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The mobile terminal provided by the embodiment of the invention is provided with the display screens on the front and back opposite surfaces (namely, the mobile terminal with the double-sided screen), and the two display screens are equivalent in the embodiment of the invention, namely, the two display screens have the functions of display and touch control. The main screen positioned on the front side of the mobile terminal can be a Liquid Crystal Display (LCD) or Organic Light Emitting Diode (OLED) display screen, and the auxiliary screen positioned on the back side of the mobile terminal can be an electronic ink screen. Illustratively, the mobile terminal may be a handset.
The display characteristics of the electronic ink screen are as follows: the image displayed on the electronic ink screen can continuously display the current image at the end of each refreshing, and the image can be continuously displayed even if the electronic ink screen is in a screen locking state.
The existing mobile terminal enables an electronic ink screen to continuously display an image when the electronic ink screen is in a screen locking state based on the display characteristic, but the display function of the electronic ink screen is single, and the display flexibility is low; the mobile terminal provided by the embodiment of the invention can realize dynamic refreshing of a plurality of images when the electronic ink screen is in a screen locking state, enriches the display function of the electronic ink screen and improves the display flexibility of the electronic ink screen.
Fig. 1 is a flowchart of an image display method for a mobile terminal according to an embodiment of the present invention, where the mobile terminal includes a main screen and a secondary screen that are oppositely disposed, and the secondary screen is an electronic ink screen. As shown in fig. 1, the method may include:
And 102, if the auxiliary screen is in the screen locking state, sequentially displaying the target images on a screen locking page of the auxiliary screen.
In the embodiment of the present invention, the screen lock state refers to a state in which the screen is locked. Because the mobile terminal is a double-sided mobile terminal, the screen states of the main screen and the auxiliary screen are consistent, namely, when the main screen is in a screen locking state, the auxiliary screen is also in a screen locking state; when the main screen is not in the screen locking state, the auxiliary screen is not in the screen locking state.
In summary, according to the image display method for the mobile terminal provided in the embodiment of the present invention, when the sub-screen display instruction is detected, a plurality of target images are obtained, and if the sub-screen is in the screen-locked state, the plurality of target images are sequentially displayed on the screen-locked page of the sub-screen. The auxiliary screen can dynamically display a plurality of target images under the screen locking state, the display function of the electronic ink screen is enriched, and the display flexibility of the electronic ink screen is improved.
Fig. 2 is a flowchart of another image display method for a mobile terminal according to an embodiment of the present invention, where the mobile terminal includes a main screen and a secondary screen that are arranged oppositely, and the secondary screen is an electronic ink screen, and the method includes:
In practical implementation, the target images may be obtained through the main screen or the sub-screen, but the display effect and the response speed of the main screen are better than those of the sub-screen, and in general, the target images are usually obtained through the main screen by the mobile terminal.
For example, when the mobile terminal receives a sub-screen display operation triggered by a user, the sub-screen display instruction may be generated. The sub-screen display operation may be a trigger operation of a user on a target application software (for example, if the system of the mobile terminal is an Android system, the target application software may be an application software installed through an installation Package (Android Package, abbreviated as APK)) or a trigger operation of a target function button, where the target application software is an application software for performing display control on the sub-screen, and the target function button is a function button in the mobile terminal for performing display control on the sub-screen.
Optionally, when the mobile terminal detects the sub-screen display instruction, the process of acquiring the plurality of target images may include: firstly, the mobile terminal displays an image to be selected on a main screen; then, after the mobile terminal receives the selection operation of the image to be selected, the plurality of target images are obtained through the main screen. The image to be selected may be an image stored in the mobile terminal or an image acquired by the mobile terminal from a server, or the image to be selected may also be an image acquired by the mobile terminal in real time through an image acquisition function (e.g., a camera function or a screenshot function).
There are various ways to display the image to be selected on the main screen, for example, the image to be selected may be displayed in a thumbnail mode, an information list mode, or a sliding window mode.
The display parameter may include at least one of a display size, a resolution, and a color, where the display size of the target image is a size of the image to be displayed, and the display size of the sub-screen is a size of an area where the sub-screen can display the image.
Assuming that the first target image is any one of the at least one target image, taking the first target image as an example, the adjustment process of the display parameter includes the following three cases:
in the first case, when the display size of the first target image is not consistent with the display size of the sub-screen, it may be detected whether an aspect ratio (i.e., a ratio of a length to a width) of the first target image is the same as the aspect ratio of the sub-screen, and when the aspect ratio of the first target image is the same as the ratio of the length to the width of the sub-screen, the first target image is scaled so that the display size of the scaled first target image is consistent with the display size of the sub-screen; when the aspect ratio of the first target image is different from that of the sub-screen, firstly, the aspect ratio of the first target image is adjusted to enable the aspect ratio of the adjusted first target image to be the same as that of the sub-screen, and then, the first target image after the adjustment is zoomed to enable the display size of the first target image after the zooming to be consistent with that of the sub-screen. The adjustment processing may be interpolation processing of an image or clipping processing of an image.
In the second case, when the resolution of the first target image is not consistent with the resolution of the secondary screen, if the resolution of the first target image is greater than the resolution of the secondary screen, the resolution of the first target image may be adjusted to be the same as the resolution of the secondary screen based on a downsampling algorithm; if the resolution of the first target image is greater than the resolution of the sub-screen, the resolution of the first target image may be adjusted to be the same as the resolution of the sub-screen based on an upsampling algorithm.
In the third case, since the image displayed on the electronic ink screen is a black-and-white image, when the color of the first target image is not consistent with the color of the secondary screen, that is, when the first target image is a color image, the adjustment processing of the first target image needs to be performed, so that the adjusted first target image is a black-and-white image.
Optionally, the adjusting process may include the following steps:
and S1, converting the first target image from the color image into a gray-scale image. For example, RGB component values of each pixel in the color image, which respectively represent a Red (Red) value, a Green (Green) value and a Blue (Blue) value in the pixel, are converted into a gray value Y of the pixel according to a preset conversion formula, which may be: y is 0.299R +0.587G + 0.114B.
And S2, optimizing the gray-scale image according to the Gamma (Gamma) value of the secondary screen and a preset optimization formula, wherein the optimized gray-scale image is the final black-and-white image. The Gamma value can be automatically configured by the mobile terminal, and the preset optimization formula can be as follows: x ═ YGammaY is the gray scale value corresponding to each pixel of the gray scale image, and X is the gray scale value corresponding to each pixel of the optimized gray scale image.
In practical implementation, the three situations may exist simultaneously, or only one or two situations may occur, and when at least two situations occur, the adjusting processes of the display parameters provided by the at least two situations may be sequentially executed, or the adjusting processes of the display parameters provided by the at least two situations may be simultaneously executed, which is not limited in the embodiment of the present invention.
In order to facilitate the next operation on the adjusted target images, the adjusted target images may be stored in the form of an image list (also referred to as an image linked list) or an image set.
And 204, if the auxiliary screen is in the screen locking state, sequentially displaying a plurality of target images on a screen locking page of the auxiliary screen. Step 205 is performed.
When a target image different from the display parameter of the secondary screen exists in the plurality of target images acquired in step 201, the plurality of target images displayed on the lock screen page of the secondary screen are adjusted plurality of target images, and the adjusted plurality of target images refer to a plurality of target images obtained by executing step 202 on the plurality of target images acquired in step 201, and at least one target image exists in the plurality of target images acquired in step 201.
When the target images with the display parameters different from those of the secondary screen do not exist in the plurality of target images acquired in step 201, the plurality of target images displayed on the lock screen page of the secondary screen are the plurality of target images acquired in step 201.
After the mobile terminal acquires the target images, it may be further detected whether the secondary screen is in the screen locking state, and when it is detected that the secondary screen is in the screen locking state, as shown in fig. 3, the mobile terminal may perform the following operations:
Optionally, a Real-Time Clock (RTC) is installed in the mobile terminal, and the periodic wake-up of the mobile terminal system may be implemented by setting a wake-up interval in the RTC. And the awakening interval in the RTC is equal to the time interval for sequentially displaying a plurality of target images on the lock screen page of the secondary screen. When the mobile terminal detects that the secondary screen is in the screen locking state, the mobile terminal acquires a pre-stored time interval, sets the awakening interval of the RTC as the time interval, triggers the RTC to start timing (or countdown), and when the awakening interval is reached, the RTC sends an awakening request to the system to awaken the system.
It should be noted that the time interval may be a default time interval preset in the mobile terminal, or may be a time interval set by the user in a self-defined manner.
For example, if the user sets the time interval to 5 minutes, when the mobile terminal detects that the secondary screen is in the screen-locked state, the system sets the wakeup interval of the RTC to 5 minutes, and triggers the RTC to start timing, and when the wakeup interval (i.e., 5 minutes) is reached, the RTC sends a wakeup request to the system to wake up the system.
Optionally, the arrangement order may have multiple forms, for example, the arrangement order may be a sequence of a selection operation on the plurality of target images or the arrangement order may be a sequence of times of storing the plurality of target images in the mobile terminal, and the like.
Alternatively, the plurality of target images may be stored in the form of an image list according to the arrangement order, and the mobile terminal may sequentially read the target images from the image list.
For example, after the secondary screen is in the screen locking state, based on a time interval, after the system is awakened for the first time, the mobile terminal reads a first target image from the image list and refreshes the first target image on a current page of the secondary screen; then the mobile terminal resets the awakening interval of the RTC to the time interval, triggers the RTC to start timing, when the awakening interval is reached, the RTC sends an awakening request to the system to awaken the system, and then the mobile terminal refreshes a second target image in the image list on the current page of the secondary screen; and by analogy, when the system is awakened each time, the target image displayed on the current page of the secondary screen is refreshed to be the next target image, so that the secondary screen can dynamically refresh a plurality of images.
In the embodiment of the invention, the mobile terminal can dynamically refresh a plurality of images, and the plurality of images can be a plurality of target images selected by the user, so that the secondary screen display of the mobile terminal is more humanized, the user experience is improved, and the phenomenon that most mobile terminals on the market have serious homogenization is improved.
And step 205, if the auxiliary screen is not in the screen locking state, displaying a default image on the current page of the auxiliary screen. Step 206 is performed.
And if the mobile terminal detects that the secondary screen is not in the screen locking state, displaying a default image on the current page of the secondary screen. Since the user is operating the main screen when the sub-screen is not in the locked state, the attention of the user is mainly focused on the main screen, and therefore, only one default image can be statically displayed on the sub-screen. Certainly, there may be more default images, or dynamic refresh images may be provided, and the dynamic refresh process may refer to step 2042, which is not described in detail in this embodiment of the present invention.
The default image may be an image preset in a system of the mobile terminal, may be any one of the target images, or may be set by a user in a self-defined manner.
Optionally, in step 201 above, when the mobile terminal detects the secondary screen display instruction, a setting interface for performing display setting on the secondary screen may be displayed on the primary screen at first, where the setting interface may include a plurality of setting options, for example, a setting option of the time interval and a setting option of a default image. When the setting option of the time interval is triggered, the mobile terminal may display a setting frame for setting the time interval on the home screen for the user to input the corresponding time interval. After the setting option of the default image is triggered, the mobile terminal may display an image to be selected on the main screen, and after the mobile terminal obtains a selection operation of the user on the image to be selected, the default image is obtained through the main screen, where the step 201 may be referred to in a process of displaying the image to be selected on the main screen.
After the mobile terminal acquires the default image, the default image may be processed with reference to the above step 202 and step 203, so that the default image is converted into a black-and-white image adapted to the secondary screen.
And step 206, after the secondary screen is in the screen locking state again, displaying a specified target image on the screen locking page of the secondary screen, wherein the specified target image is the last target image displayed when the secondary screen is in the screen locking state last time.
After the mobile terminal detects that the secondary screen is in the screen-locked state again, it may perform an action of sequentially displaying a plurality of target images, and the process may refer to step 204 above.
After the step 204, if the mobile terminal detects that the secondary screen is not in the screen-locked state (that is, it is detected that the secondary screen is switched from the screen-locked state to the screen-unlocked state), the image list may be refreshed, and a specified target image is displayed on the screen-locked page of the secondary screen according to the updated image list, where the specified target image may be a last target image displayed when the secondary screen is in the screen-locked state last time. Of course, the specified target image may also be any one of the target images in the image list, and the embodiment of the present invention is not limited herein.
In practical implementation, the mobile terminal may set a daemon process in the system, the daemon process performing an image display method for executing the above mobile terminal. For example, in step 201, when the mobile terminal detects a sub-screen display instruction, the daemon process may be started, and a structural body of an image and a structural body of a time interval are created in the daemon process, where the structural body of the image is used to set display parameters of an image, such as a display size, a resolution, a color, and the like, the image may include the plurality of target images and a default image, and after the daemon process acquires an image that can be displayed on the sub-screen (that is, the display parameters of the image are the same as those of the sub-screen), the daemon process stores the image in the structural body. The daemon process also stores a structure with a time interval, and referring to step 204, the daemon process can set a wakeup interval of the RTC according to the structure with the time interval. Further, in step 204, if the secondary screen is in the screen-locked state, the RTC may periodically wake up a daemon process in the system of the mobile terminal according to the wake-up interval, and the daemon process refreshes the target image displayed on the current page of the secondary screen into a next target image after waking up each time according to the arrangement sequence of the target images; in step 205, if the secondary screen is not in the screen locking state, the daemon process displays the stored default image on the current page of the secondary screen; in step 206, after the secondary screen is in the locked screen state again, the daemon process displays a specified target image on the locked screen page of the secondary screen, wherein the specified target image is the last target image displayed when the secondary screen is in the locked screen state last time. Of course, the steps 202 and 203 may also be executed by a daemon process, and are not described again in this embodiment of the present invention.
