Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present application are proposed.

Fig. 3 is a flowchart of a method of an implementation manner of a screen projection method according to an embodiment of the present application. In this embodiment, the screen projection method may be applied to the mobile terminal shown in fig. 1 or fig. 2, and it is understood that the screen projection method may also be applied to electronic devices such as a tablet and an electronic book. The screen projection method comprises the following steps:

step S310, screen parameters of a screen projection end are obtained;

step S320, dividing screen physical pixels of the receiving end into virtual pixels according to screen parameters of the screen projection end, wherein the virtual pixels comprise at least one screen physical pixel;

and step S330, displaying the screen projection picture of the screen projection end according to the virtual pixel.

Through the implementation, in the process of projecting the screen to the receiving end through the screen projecting end, especially when the resolution of the display device at the screen projecting end is different from that of the display device at the receiving end, the receiving end divides the screen pixels of the display device again according to the screen parameters of the screen projecting end, and the screen physical pixels of one or more similar receiving ends are formed into a whole as a virtual pixel. By the mode, the best display effect of the projection screen is improved, and stretching or abnormal display is avoided.

Specifically, in step S310, screen parameters of the screen projection end are acquired. And a screen projection data channel between the screen projection end and the receiving end is established, and the screen projection end sends the screen projection data to the receiving end through the data channel, so that the receiving end can convert the screen projection data into corresponding screen projection pictures and display the pictures after receiving the screen projection data. In the present embodiment, the screen projection terminal is a mobile terminal, for example, a mobile phone, a pad, etc.; the receiving end is a television or a computer. And the screen projection data is a picture corresponding to a display interface of the screen projection end. In this embodiment, the screen parameter is a pixel ratio, which is a row-column ratio of pixels, for example, the pixel ratio is 1280x 720.

In a specific implementation process, after the connection between the screen projecting end and the receiving end is established, the screen projecting end reads the screen parameters and sends the screen parameters to the receiving end, so that the receiving end can acquire the screen parameters of the screen projecting end.

In step S320, as shown in fig. 4, the screen physical pixels of the receiving end are divided into virtual pixels according to the screen parameters of the screen projection end, where the virtual pixels include at least one screen physical pixel. Specifically, the screen physical pixels refer to real pixels constituting the screen, and the screen of 1280x720 resolution as mentioned above is constituted by 1280x720 physical solid pixels. The virtual pixel refers to a screen region including a plurality of physical pixels formed by logically dividing a screen. The screen parameter specifies the arrangement parameter of the screen pixels. In this embodiment, the screen parameter is a pixel ratio, and the pixel ratio is a row-column ratio of pixels. In an optional implementation manner, the pixel proportion of the virtual pixels at the receiving end is the same as or similar to the pixel proportion at the screen projecting end, and in the process of dividing the screen pixels at the receiving end into the virtual pixels, the virtual pixels are in the convenient requirement or the implementable requirement of pixel division, and the virtual pixels are not strictly divided according to the pixel arrangement condition of the screen at the screen projecting end, but are distributed similarly as far as possible.

Specifically, step S320 may include the steps of:

step S3201, acquiring a screen physical pixel arrangement parameter of the receiving end, where the arrangement parameter includes a physical pixel line number and a physical pixel column number of the screen;

step S3202, determining at least one physical pixel in the same divided area in the screen physical pixels according to the screen parameters of the screen projection end and the arrangement parameters;

in step S3203, at least one physical pixel in the same divided area is determined as a virtual pixel.

Specifically, the number of physical pixel rows of the screen refers to how many rows, for example, 100 rows, of pixels constituting the screen, and the number of physical pixel columns of the screen refers to how many columns, for example, 100 columns, of pixels constituting the screen, that is, the physical pixels of the screen are constituted by 100 × 100 pixels, and the virtual pixels are formed by dividing the physical pixels into a plurality of pixel groups.

Wherein step S3202 may include the steps of:

step S32021, uniformly dividing the physical pixel line number and the physical pixel column number of the receiving end into a plurality of virtual lines and a plurality of virtual columns according to the row-column comparison of the pixels of the screen projection end;

step S32022, the screen of the receiving end is divided into a plurality of virtual areas by a plurality of virtual rows and a plurality of virtual columns, wherein the virtual areas include at least one physical pixel.

Specifically, the purpose of the application is to divide the screen pixels of the receiving end according to the screen pixel situation of the screen projection end to form virtual pixels similar to the screen pixel situation of the screen projection end. Therefore, after the pixel row-column ratio of the screen pixels at the screen projection end is obtained, the rows and columns of the physical pixels of the screen at the receiving end are uniformly divided into corresponding fractions according to the row-column ratio, and then the screen at the receiving end can be divided into a plurality of virtual areas through the divided rows and columns. For example, if the row-column ratio of the projection end pixels is 51 × 32, the number of the physical pixel rows on the screen of the receiving end is divided into 51 rows, and the number of the physical pixel rows on the screen of the receiving end is divided into 49 rows, and due to the requirement of feasibility, the physical pixel rows of the receiving end are divided into 50 virtual rows, and each virtual row comprises 2 physical pixel rows; and dividing the physical pixel columns of the receiving end into 32 virtual columns, wherein each virtual column comprises 3 physical pixel columns, the rest physical pixel columns which are not divided do not form a forming part of the virtual pixels, and a virtual area formed by each divided virtual row and each virtual column comprises 6 physical pixels.

In step S3203, the screen of the original receiving end is divided into screens composed of 50 × 32 virtual pixels by dividing into 50 virtual rows and 32 virtual columns, for example.

Through the embodiment, the virtual pixel composition condition of the divided screen is very similar to the screen pixel composition condition of the screen projection end, so that the picture proportion of the screen projection picture used for presenting the screen projection end is nearly the same as that of the screen projection picture, the picture stretching or compression can be effectively avoided, and the screen projection picture quality is improved.

Specifically, step S330 may include the steps of:

step S3301, receiving a screen projection picture transmitted by the screen projection end according to the virtual pixel;

and step S3302, displaying the corresponding picture pixels in the screen projection picture through the virtual pixels.

In step S3301, the screen projection end sends the corresponding pixel content to the receiving end according to the distribution of the virtual pixels. Step S3302 may include the steps of:

and displaying the first picture pixel through the first virtual pixel.

Specifically, in this embodiment, before the screen projection picture is sent to the receiving end, the corresponding relationship between the screen pixel of the screen projection end and the screen virtual pixel of the receiving end is established according to the divided virtual pixels, for example, the first physical pixel at the upper left corner of the screen pixel of the screen projection end corresponds to the first virtual pixel at the upper left corner of the screen of the receiving end composed of the virtual pixels, and as an example, the first physical pixel at the upper left corner of the screen pixel of the screen projection end corresponds to 6 physical pixels in the upper left corner area of the screen of the receiving end (i.e., the first two rows at the upper left corner and the first 6 physical pixels at the first three columns). The screen projection picture is a picture formed by pixel values of all pixels of the screen at the screen projection end, therefore, each picture pixel of the screen projection picture can be mapped to one pixel of the screen at the screen projection end, and further a virtual pixel corresponding to the screen pixel can be used, and the corresponding picture pixel is further displayed through the virtual pixel, so that the screen projection picture is displayed through a display area formed by the virtual pixel.

According to the screen projecting method, in the process of projecting the screen to the receiving end through the screen projecting end, especially when the resolution of the display device at the screen projecting end is different from that of the display device at the receiving end, the receiving end divides the screen pixels of the display device again according to the screen parameters of the screen projecting end, and the screen physical pixels of one or more similar receiving ends are formed into a whole to be used as a virtual pixel. By the mode, the best display effect of the projection screen is improved, and stretching or abnormal display is avoided.
