Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method. The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal (such as a mobile phone, a computer, a server, an air conditioner, or a network device) to execute the method according to the embodiments of the present invention.

Further, the processor 110 may call the display program of the double-sided screen stored in the memory 109, and further perform the following operations:

and running the uncommon application program on the secondary screen.

The invention further provides a double-sided screen display method. Referring to fig. 3, fig. 3 is a schematic diagram of a double-sided display method according to a first embodiment of the present invention.

In this embodiment, the double-sided screen display method includes:

step S10, acquiring the content to be displayed on the screen, and determining the display category of the content to be displayed;

in this embodiment, the content to be displayed refers to content to be displayed by the mobile terminal, for example, a user selects a picture to be viewed in an album, and clicks the picture to trigger a viewing instruction, the mobile terminal receives the display instruction of the user and displays the picture on a display interface, or when the user selects a movie to play in a video application, the content to be displayed is video data corresponding to the movie. The display category includes pictures, characters, videos, games and the like, and specifically, when a display instruction triggered by operations such as user clicking, sliding and the like is received, data of the content to be displayed corresponding to the display instruction is acquired, the data corresponding to the content to be displayed is analyzed, and the display category corresponding to the content to be displayed is determined according to an analysis result.

Step S20, acquiring a first attribute parameter of the content to be displayed, and determining a first display parameter of the content to be displayed based on the display category and/or the first attribute parameter, wherein the first display parameter corresponding to the display category is searched in a preset parameter table;

in this embodiment, the first attribute parameters include resolution, contrast, and the like, where the resolution refers to the number of pixels displayed on the screen, and of course, a larger number of pixels means a clearer screen and a higher sharpness of expression of characters, and the contrast of an image refers to a ratio between the brightest and darkest areas of the image, and a larger ratio results in more gradation from black to white, so that the color expression is richer. That is, if the contrast of the image is small, the gradation level from black to white between the brightest and darkest of the image is small, so that the difference between the color and brightness of two adjacent pixels is correspondingly small. The frame rate is the number of frames displayed per second, and when the frame rate of a picture seen by human eyes is higher than 16, the picture is considered to be coherent, and the phenomenon is called persistence of vision. The higher the fluency of the video or game, the higher the frame rate of the video or game. Generally, the resolution of the primary screen is different from that of the secondary screen, for example, the resolution of the primary screen is 2K, and the resolution of the secondary screen is 720P. The resolution requirements of each application are different, for example, the resolution required by a movie player is higher, and the resolution required by novice software is lower, and when an application start instruction is received, the appropriate resolution of the application will be obtained, and of course, the attribute parameters of the main screen and the sub-screen may also be the same. The content to be displayed refers to content to be displayed by the mobile terminal, and includes a text type, a video type and a picture type, and attribute parameters corresponding to different display contents are different, for example, the resolution of the display content of the picture type is higher than that of the text type compared with the picture type. The preset parameter table includes display parameters corresponding to different types of display contents, and the display parameters corresponding to the display type can be found in the preset parameter table, for example, the resolution corresponding to a text type and the resolution corresponding to a picture type can be found in the preset parameter table.

Further, the first display parameter includes a screen resolution, a frame rate, a brightness, and the like, a processing capability of a CPU of the mobile terminal is proportional to the resolution and the frame rate, and when the CPU processing capability is managed to increase, power consumption will also increase, so that the power consumption of the mobile terminal can be reduced by adjusting the resolution and the frame rate, for example, when the contrast of an image is small, gradient levels from black to white between the brightest and darkest of the image are less, so that a difference between a color and a brightness between two adjacent pixels is correspondingly reduced, and even if the screen resolution of the display screen is reduced to some extent, human eyes cannot distinguish the image, so in this case, the screen power consumption can be reduced by reducing the screen resolution, and the first display parameter corresponding to the first attribute parameter can be determined by a preset parameter table or a preset parameter curve. The first attribute parameter of the content to be displayed may be determined through a preset parameter table or a preset parameter curve, specifically, the preset parameter table includes a display category of the content to be displayed, a first display parameter corresponding to the display category, a first attribute parameter, a first display parameter corresponding to the first attribute parameter, and the like, the display category and the first display parameter, the first attribute parameter and the first display parameter form a mapping relationship, the first display parameters corresponding to different display categories may be different, for example, a screen resolution corresponding to a text category is 1000P, a screen resolution corresponding to a game category is 720P, and a resolution corresponding to a picture category is 1080P. Of course, the first attribute parameters are different, and the corresponding first display parameters are also different, for example, if the image contrast is a, the screen resolution corresponding to a is 720P, and if the image contrast is b, the screen resolution corresponding to b is 800P. Of course, the first display parameter of the to-be-displayed category can also be determined according to a preset parameter curve, the abscissa of the to-be-displayed curve can be the first attribute parameter, the ordinate can be the first display parameter, and the first display parameter is subjected to corresponding linear change along with the change of the first attribute parameter.

And step S30, displaying the content to be displayed based on the first display parameter.

In this embodiment, the first display parameters include the resolution, the frame rate, and the like of the screen, and the adjustment of the first display parameters of the screen displays the display category, and with the increasing abundance of the functions of the mobile terminal, the game has become an important application of each mobile terminal, which is an important way for the user to entertain outside the work. However, as the complexity of the game is continuously increased, the power consumption of the game is increased, which causes the power consumption of the mobile terminal to be increased and the cruising ability to be reduced. For a game scene, users generally pay more attention to the fluency than the definition of pictures, for example, when the resolution of the pictures is reduced from 1080P to 720P, the users generally feel that the pictures have no great change. At present, the resolution of mobile terminals such as mobile phones is mostly 1080P, and if the screen resolution of a game is reduced to 720P, the workload of a GPU can be obviously reduced, so that the frequency of the GPU is kept low, the power consumption of a game scene can be reduced, and the power consumption of the mobile terminals can be reduced.

In the method for displaying a double-sided screen provided by this embodiment, a to-be-displayed content to be displayed on a screen is acquired, a display category of the to-be-displayed content is determined, then a first attribute parameter of the to-be-displayed content is acquired, a first display parameter of the to-be-displayed content is determined based on the display category and/or the first attribute parameter, wherein a first display parameter corresponding to the display category is searched in a preset parameter table, and finally the to-be-displayed content is displayed based on the first display parameter; the corresponding first display parameters are determined according to the display type and/or the first attribute parameters of the type contents to be displayed, so that the power consumption of a screen for the mobile terminal can be reduced, and the utilization rate of a battery of the mobile terminal is increased.

Based on the first embodiment, a second embodiment of the double-sided screen display method of the present invention is provided, and referring to fig. 4, in this embodiment, step S20 includes:

step S21, obtaining the image resolution of the content to be displayed, and determining whether the image resolution is within a preset range;

step S22, if the image resolution is within the first preset range, adjusting the screen resolution to be consistent with the image resolution;

step S23, if the image resolution is not within the first preset range, calculating a screen resolution corresponding to the image resolution by using a preset parameter curve.
