The manner of full screen display is the same as in the prior art and is not described here in any way.
In the above embodiment, the process of receiving the split display instruction and determining the split regions according to the split display instruction, generating the display parameters of each split region is performed in synchronization with the process of triggering the split display instruction by the user plane and performing the setting of each parameter item of the split region.
In the embodiment of the invention, a user initiates a split screen display instruction and sets each parameter item of a split screen area through one piece of software. For example, a screen parameter management system is used for realizing the process of initiating a split screen display instruction by a user plane and setting each parameter item of a split screen area.
The following is a description of a specific example shown in fig. 2.
Step S1: the user logs in the screen parameter management system, and the display mode which can be selected is displayed on the display interface of the display screen, the split screen display can be selected, and the split screen display can also be selected.
If the user selects the split screen display, the user sets up each item of the split screen display, and the screen parameter management system reports the information to the processor as a split screen display instruction.
If the user selects full-screen display (step S6 illustrated in the figure), the screen parameter management system, as a functional module of the processor, reports a full-screen display instruction to the processor in the embodiment of the present invention, and the full-screen display content defaults to the content that is opened on the current display interface, without special setting.
Step S2: the user selects the split screen display and enters the next setting interface of the split screen display;
step S3: setting a split screen proportion by a user;
the user selects a split ratio from preset split ratios, or the user defines a split ratio. After the user sets the split ratio, a plurality of split areas divided by the display screen can be presented to the user in a preview mode under the split ratio.
If the split screen ratio set by the user is 1:1:2, the split screen region preview corresponding to the split screen ratio comprises the sizes of 3 split screen regions and the relative positions of the 3 split screen regions. The user can default the relative positions of the 3 split screen areas in the preview image, and can drag each split screen area to set the relative positions of the 3 split screen areas. For example, referring to fig. 3, the relative positions of 3 split screen areas set by the user are split screen area 1, split screen area 2, and split screen area 3, which are respectively located below, upper left and upper right of the display screen.
Through this step, the processor determines the positions of the split screen area 1, the split screen area 2 and the split screen area 3 on the display screen according to the setting of the user, and searches the preset corresponding relation between the multiple split screen areas (split screen area positions) and the multiple display control chips, if the corresponding relation between the positions of the split screen areas and the display control chips under the condition of 1:1:2 is prestored in the display device, the processor finally determines the display control chips respectively corresponding to the split screen area 1, the split screen area 2 and the split screen area 3, for example, as shown in fig. 3, the processor finally determines the display control chips 1 corresponding to the split screen area 1 and the display control chips 2 corresponding to the split screen area 2 and the split screen area 3.
Meanwhile, as shown in the connection relationship shown in fig. 3, the processor may also send an instruction to the display control chip 1, instruct the display control chip 1 to control the display of the split screen area 1, and send an instruction to the display control chip 2, instruct the display control chip 1 to simultaneously control the display of the split screen area 2 and the split screen area 3.
Step S4: the user sets the display effect of each split screen area; for each split screen area, step S4 further includes:
step S41: setting parameters such as brightness, gray scale and the like;
the user can adjust the parameters of saturation, gray scale, brightness and the like of each split screen area. For example, the user sets parameters such as brightness, resolution, saturation, and the like for the split screen area 1, the split screen area 2, and the split screen area 3, respectively.
Step S42: setting a display type, namely selecting a mirror image display mode and an independent display mode, and entering a setting interface of the step S43 if the independent display mode is selected by a user;
for example, the user sets the independent display mode for the split screen area 1, the split screen area 2, and the split screen area 3. Then the settings of the application program are also required to be displayed independently for the split screen area 1, the split screen area 2 and the split screen area 3, respectively.
Step S43: setting of an application setting item;
after the user sets a certain application program in the step, the data corresponding to the application program is independently displayed in the corresponding split screen area.
Through this step, the processor obtains the application program identifier corresponding to each split screen area and the data corresponding to the application program identifier. For example, the user sets corresponding application 1, application 2, and application 3 for the split screen area 1, split screen area 2, and split screen area 3, respectively, and then the processor obtains the application corresponding to the split screen area 1 as application 1, the application corresponding to the split screen area 2 as application 2, and the application corresponding to the split screen area 3 as application 3.
After the user setting is finished, the setting is saved.
Step S5: the processor generates display parameters for each split screen region according to the setting information of steps S41 to S43 performed by the user for each split screen region.
For example, the processor generates the display parameters of the split screen area 1 based on the above-described setting information of steps S41 to S43 for the split screen area 1 by the user, generates the display parameters of the split screen area 2 based on the above-described setting information of steps S41 to S43 for the split screen area 2 by the user, and generates the display parameters of the split screen area 3 based on the above-described setting information of steps S41 to S43 for the split screen area 3 by the user.
Based on the above steps, the processor is also able to: the display parameters of the split screen area 1 are sent to the display control chip 1, and the display parameters of the split screen area 2 and the display parameters of the split screen area 3 are sent to the display control chip 2. The display parameters of the split screen area 2 and the display parameters of the split screen area 3 carry the identification of the split screen area to which the split screen area belongs, so that the display control chip 2 can distinguish which display parameters are of the split screen area 2 and which display parameters are of the split screen area 3.
After which the processor is further capable of: sending an initialization instruction to the display control chip 1 and the display control chip 2, so that after the display control chip 1 receives the initialization instruction, initializing a display interface of the split screen area 1 according to the display parameters of the split screen area 1; after receiving the initialization instruction, the display control chip 2 initializes the display interface of the split screen area 2 according to the display parameters of the split screen area 2, and initializes the display interface of the split screen area 3 according to the display parameters of the split screen area 3.
After which the processor is further capable of: the data of the application program 1 is acquired and distributed to the memory space of the display control chip 1, the data of the application program 2 and the data of the application program 3 are acquired, and the data of the application program 2 and the data of the application program 3 are distributed to the memory space of the display control chip 2. Likewise, the data of the application 2 and the data of the application 3 carry the application identifier, so that the display control chip 2 can distinguish which are the split screen areas 2 and which are the split screen areas 3.
After that, the display control chip 1 continuously reads the data of the application 1 from the memory space of the display control chip 1, and drives the display pixels in the split screen area 1 to display according to the data of the application 1. The display control chip 2 continuously reads data of the application 2 from the memory space of the display control chip 2, drives display pixels in the split screen area 2 to display according to the data of the application 2, and reads data of the application 3, and drives display pixels in the split screen area 3 to display according to the data of the application 3.
The user can divide the display screen into two parts through the split screen arrangement of the steps S1 to S5, and the two parts of the areas respectively execute different operations, for example, one part is used for a working interface and the other part is used for a game interface, so that the working game can be realized without errors. The user may also customize the display effect of each split screen area through the split screen settings of steps S1 to S5, for example, the display effect is set to be the display effect in the movie watching scene, and the display effect is set to be the display effect in the book watching scene. Thus, the user can enjoy better effects brought by the display device aiming at different application scenes.
In summary, in the embodiment of the invention, the display parameters of different split screen areas are determined according to the split screen display instruction of the user, so that the user can be allowed to customize the display effect independently for each split screen area, and the user can customize different display effects for more diversified scenes through split screen setting, so that the degree of freedom of user customization is high. And different split screen areas are controlled to be displayed by different display control chips, and the display content of each split screen area can be independently set, so that split screen display of a display screen can be truly realized.
In addition, through the setting of split screen, can also reach the effect of power saving, when low electric quantity, the user sets up through the split screen, can reduce the display area, and the region that need not show can be set to the black screen, and then reaches the purpose of saving the electric quantity.
