Detailed Description

Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

At present, with the development of vehicle-related technologies, ways for providing information to users in vehicles are becoming more and more abundant. Especially, the information is provided for the user through the vehicle-mounted display screen, so that the information display mode is more visual, and the display content is more abundant.

Wherein, can set up a display screen in the vehicle, this display screen can be connected with the car machine end, sends the information that needs to show to the display screen through the car machine end. The vehicle terminal may be, for example, a vehicle-mounted computer.

Meanwhile, other electronic equipment can be arranged in the vehicle besides the vehicle-mounted terminal, and the electronic equipment can be arranged when the vehicle leaves the factory or can be installed later according to the requirements of a user. Some electronic equipment can be connected with the vehicle-mounted terminal, and then can throw the screen to the on-vehicle display screen through the vehicle-mounted terminal.

Specifically, because the screen content has uncertainty, in order to display the complete screen content in the prior art, the picture to be put in is directly distributed in the middle of the screen, specifically the content to be displayed is extruded to the middle part of the screen, specifically to the middle part of the screen in the horizontal and vertical directions, and the mode leads to wasting the redundant display area in the screen and the display content is not outstanding. Therefore, when a user views the display screen, most of the blank area exists, and the real screen-throwing content display area is smaller, so that the user experience is poor.

In the scheme provided by the application, the corresponding display template is set based on the attribute information of the target screen, and when the screen is thrown, the display template can be adjusted according to the attribute information of the target screen and the display template corresponding to the screen, and the acquired content is displayed in the target screen through the adjusted display template. According to the scheme provided by the application, the corresponding display template can be determined according to the attribute information of the screen, and further the display template is adjusted, so that when the content is displayed through the display template, the area for displaying the information in the target screen can be fully utilized.

Fig. 1 is a schematic view of an application scenario according to an exemplary embodiment of the present application.

As shown in fig. 1, the solution provided in this embodiment may be applied to a vehicle as shown in fig. 1, in which a vehicle-mounted display screen 11 and an electronic device 12 may be provided.

The electronic device 12 may be directly connected to the vehicle-mounted display screen 11, or may be connected to the vehicle-mounted display screen 11 through a vehicle-mounted terminal (e.g., a vehicle-mounted computer, not shown). The electronic device 12 may be, for example, a drive recorder, a navigation system, or the like provided in a vehicle.

The electronic device 12 may also have a screen, and in particular, the user may operate the electronic device 12 to cause its screen to display desired information. When the electronic device 12 is in a state of being screen-projected onto the in-vehicle display screen 11, information to be displayed can be screen-projected onto the in-vehicle display screen 11.

It should be noted that, the scheme provided in this embodiment may also be applied to other scenes where screen projection is required.

Fig. 2A is a schematic diagram illustrating connection between an electronic device and a vehicle-mounted display screen according to an exemplary embodiment of the present application.

As shown in fig. 2A, in one embodiment, the electronic device 12 may be directly connected to the in-vehicle display screen 11. The electronic device 12 may directly send information to be displayed to the in-vehicle display screen 11, so that the in-vehicle display screen 11 displays content to be displayed.

Fig. 2B is a schematic diagram illustrating connection between an electronic device and an in-vehicle display screen according to another exemplary embodiment of the present application.

In another embodiment, as shown in fig. 2B, the electronic device 12 is connected to the in-vehicle display 11 through the vehicle terminal 13. The electronic device 12 can send information to be displayed to the vehicle-mounted terminal 13, and then send the information to be displayed to the vehicle-mounted display screen 11 through the vehicle-mounted terminal 13, so that the vehicle-mounted display screen 11 displays content to be displayed.

Fig. 3 is a flowchart of a screen projection method according to an exemplary embodiment of the present application.

As shown in fig. 3, the screen projection method provided in the present application includes:

step 301, obtaining attribute information of a target screen, and determining a display template corresponding to the target screen according to the attribute information.

The method provided in this embodiment may be performed by an electronic device with computing capability, and the electronic device may be any one of the electronic devices shown in fig. 1, 2A, and 2B, for example.

Specifically, step 301 may be performed when a screen is required, or may be performed before the screen is projected. For example, the electronic device may perform step 301 after setting the electronic device to the screen-casting state.

Further, the target screen refers to a screen to be projected, and if the method provided in this embodiment is applied to a vehicle, the target screen may be any vehicle-mounted display screen as shown in fig. 1, 2A, and 2B.

In practical application, the electronic device may acquire attribute information of the target screen, where the attribute information may include resolution of the target screen, and may further include aspect ratio of the target screen, and the like. If the electronic device is directly connected with the target screen, the attribute information can be read from the target screen. If the electronic equipment is connected with the target screen through the vehicle-mounted terminal, the electronic equipment can read the attribute information from the vehicle-mounted terminal.

The resolution of the target screen refers to the display resolution, the precision of the screen image, and how many pixels the display can display. Since the points, lines and planes on the screen are all composed of pixels, the more pixels the display can display, the finer the picture, and the more information can be displayed in the same screen area.

Wherein, display templates can also be arranged in the electronic equipment, and the resolutions of different display templates can be different. The resolution of the template refers to the image resolution and is the number of pixels contained in a unit inch.

The attribute information of the target screen may be different, and the corresponding display templates may be different. A plurality of display templates may be provided in the electronic device, for example, 2, 3, or the like display templates may be provided. For example, two display templates may be provided, one for a relatively wide target screen and the other for a normal target screen. The aspect ratio of the target screen can be determined according to the attribute information of the target screen, whether the target screen is a wider screen or not is measured according to the aspect ratio, and then the corresponding display template is determined according to the judging result.

In an alternative embodiment, the electronic device may record the display template corresponding to the target screen, so that this step need not be performed every time the screen is thrown. For example, the correspondence between the target screen identification and the display template identification is recorded.

The display template may further include fixed components, such as each key included in the menu portion, and further include a component for displaying a title, etc. These components also pertain to what needs to be displayed.

Fig. 4 is a schematic diagram of a display template according to an exemplary embodiment of the present application.

As shown in fig. 4, a plurality of components, such as a menu component 41, a key component 42, a display component 43, and a title component 44, are included in the display template. The display template may include a plurality of menu components 41, or a plurality of key components 42, and may also include a plurality of display components 43. The display template may be set according to a style of the electronic device display information, for example, when the electronic device displays the information while 3 menu components 41 are displayed, the display template may also have 3 menu components 41.

Wherein, the types of components included in different display templates may be the same, and specific component sizes may be different.

Step 302, determining a scaling ratio according to the attribute information and the display template, and adjusting the display template according to the scaling ratio.

Specifically, after determining the display template corresponding to the target screen, a scaling may be determined according to the attribute information and the display template of the target screen. The scale is used to adjust the display template.

Further, since the sizes of the target screens are different, if the corresponding display templates are provided for each size of the target screen, the number of display templates is large. Accordingly, it is possible to make a plurality of sizes of target screens correspond to the same display template, thereby reducing the number of display templates.

In practical application, since the same display template corresponds to a plurality of target screens, if the display template is directly used for displaying information in the target screens, the problem of incomplete information display or more blank areas in the target screens may be caused. Therefore, the method provided by the embodiment also determines a scaling ratio according to the attribute information of the target screen and the display template, and adjusts the display template by using the scaling ratio. So that the display template is suitable for the current target screen.

In this embodiment, although a corresponding display template is not set for each size of target screen, by adjusting the display template with the target screen, the adjusted display template can be applied to the target screen, and thus information can be personalized for different sizes of target screens.

When the scaling is used for adjusting the display template, the scaling can be used for adjusting the size of each component included in the display template, and the distance between the components can be adjusted, so that the display template is more in line with the attribute information of the target screen. For example, the length and width of the components in the display template can be multiplied by the scaling, and after the display template is adaptively adjusted, the display effect of the display template can be ensured not to be deformed.

In one embodiment, the electronic device may record a scaling ratio corresponding to the target screen, for example, record a correspondence between the target screen identifier and the display template identifier, and further record a correspondence between the target screen identifier and the scaling ratio, so as to directly obtain the information to adjust the display template when the screen is required to be thrown.

In another embodiment, the electronic device may also directly record the adjusted display template corresponding to the target screen. For example, after the user sets the electronic device to the screen-on state, the electronic device may perform steps 301-302, thereby obtaining an adjusted display template, and recording the display template.

When the target screen is required to be controlled to carry out screen projection display, the display template and the scaling corresponding to the electronic equipment can be directly obtained, or the adjusted display template can be directly obtained, and the screen projection is carried out by utilizing the obtained information, so that the response speed of the screen projection is improved.

Step 303, obtaining display content.

The electronic device may obtain display content, where the display content refers to information that needs to be displayed on a screen. For example, the user may send an instruction to the electronic device, so that the electronic device obtains the display content, and may specifically issue an instruction to the electronic device by means of voice, operating a touch screen, or the like. For another example, the electronic device may obtain display content based on internal logic, such as an emergency news, and the electronic device may automatically obtain the emergency news.

The execution timing of step 303 and steps 301-302 is not limited.

In one embodiment, step 303 may be performed first. That is, the electronic device may first acquire the display content, determine whether the display content is in the screen-casting state, and if so, execute steps 301 to 302, and then execute step 304.

In another embodiment, steps 301-302 may be performed before step 303 is performed. For example, the user may set the electronic device to a screen-cast state, at which point the electronic device may perform steps 301-302. Thereafter, the electronic device may obtain the display content and perform step 304 based on the obtained display content.

In yet another embodiment, steps 301-302 and step 303 may be performed simultaneously. For example, the electronic device is set to be in a screen-throwing state, and the electronic device can acquire display content based on user operation or own logic, and meanwhile, the electronic device can execute steps 301-302, and then execute step 304.

And step 304, displaying the display content in the target screen according to the adjusted display template.

The electronic device can put the acquired display content in the adjusted display template and control the target screen to display.

Specifically, a display module for displaying the content may be provided in the display template, and the acquired display content may be placed in the display module.

Fig. 5 is a schematic diagram of an adjusted display template provided with display content according to an exemplary embodiment of the present application.

As shown in fig. 5, the sizes of the respective components are adjusted according to the scaling, and display contents are embedded in the display component 51.

Further, if the electronic device is directly connected to the target screen, the electronic device may send the adjusted display template with the embedded display content to the target screen, so that the target screen is directly displayed.

In practical application, if the electronic device is connected with the target screen through the vehicle terminal, the electronic device can send the adjusted display template embedded with the display content to the vehicle terminal, and the vehicle terminal controls the target screen to display specific content.

The display template is displayed in the target screen based on the adjusted display template, so that the display effect can be more consistent with the display effect of the target screen.

The method provided by the present embodiment is used for screen projection, and the method is executed by a device provided with the method provided by the present embodiment, and the device is usually implemented in a hardware and/or software manner.

The screen projection method provided by the application comprises the following steps: acquiring attribute information of a target screen, and determining a display template corresponding to the target screen according to the attribute information; determining a scaling ratio according to the attribute information and the display template, and adjusting the display template according to the scaling ratio; and acquiring display content, and displaying the display content in the target screen according to the adjusted display template. According to the screen projection method, the display template corresponding to the target screen can be obtained, and the display template can be adjusted to be more matched with the target screen, so that when the content is displayed in the target screen through the display template, the area for displaying information in the target screen can be fully utilized, the information display efficiency is improved, and the user experience is further improved.

Fig. 6 is a flowchart illustrating a screen projection method according to another exemplary embodiment of the present application.

As shown in fig. 6, the screen projection method provided in the present application includes:

step 601, a voice command is received, and display content is determined according to the voice command.

Specifically, the electronic device may have a microphone for receiving and recognizing a voice command of a user. For example, the electronic device may have a semantic recognition algorithm, and the voice instruction spoken by the user may be converted into a text instruction, and then the text instruction is sent to the background server through the network, so that the background server feeds back the display content.

Step 602, determining whether the screen is in a screen-throwing state.

Further, the electronic device may determine whether the current state is a screen-throwing state, if so, execute step 603, otherwise, may display the display content based on its own display screen.

In practice, the electronic device itself may also have a display screen, which may also be used to display information.

In this embodiment, the electronic device can normally display the acquired display content even when the electronic device is not in the screen-throwing state.

Step 603, obtaining resolution information of the target screen, and determining the aspect ratio of the target screen according to the resolution information.

Specifically, the target screen refers to a screen to be projected, and if the method provided in this embodiment is applied to a vehicle, the target screen may be any vehicle-mounted display screen as shown in fig. 1, 2A, and 2B.

Further, the electronic device may obtain resolution information of the target screen, where the resolution information may be a specific resolution value, for example, m×n, where m is used to indicate the number of pixels that can be displayed on the target screen in the landscape direction, and n is used to indicate the number of pixels that can be displayed on the target screen in the portrait direction.

In practical applications, the resolution of the screen is different, and when the content having the same layout is displayed, the display effect is also different. Therefore, in the method provided by the embodiment, the final typesetting result is determined by using the resolution of the target screen, so that the typesetting result matched with the target screen can be determined.

Wherein the aspect ratio of the target screen can be determined specifically based on the resolution information. For example, if the acquired resolution information is m×n, the aspect ratio of the target screen may be determined to be m/n.

Step 604, comparing the aspect ratio with a predetermined ratio.

Specifically, a preset ratio may be preset, and the target screen may be classified according to the preset ratio. For example, the target screens having an aspect ratio greater than a preset ratio may be classified into one type, and the target screens having an aspect ratio less than or equal to the preset ratio may be classified into another type.

Further, the target screen can be divided into two types by a preset ratio, one type is a wider screen, and the other type is a common screen. Therefore, the information is displayed based on the characteristics of the target screen, and the displayed information is more in line with the target screen.

The preset ratio can be set according to requirements, for example, can be 2.1.

Step 605, if the aspect ratio is greater than the preset ratio, determining the display template corresponding to the target screen as the first template.

And step 606, if the aspect ratio is smaller than or equal to the preset ratio, determining the display template corresponding to the target screen as a second template.

In practical application, the first template and the second template can be preset and respectively applied to target screens with different characteristics. Wherein the aspect ratio of the first template is greater than the aspect ratio of the second template, the aspect ratio being calculated from the resolution of the templates, e.g. the resolution of the templates is m '/n', then the aspect ratio of the templates is m '/n'.

Wherein the aspect ratio of the first template is larger, which is more suitable for the screen with larger aspect ratio. Therefore, if the aspect ratio of the target screen is greater than the preset ratio, the first template is determined to be the display template corresponding to the target screen. The second template has a smaller aspect ratio, which is more suitable for a screen with a smaller aspect ratio. Therefore, if the aspect ratio of the target screen is smaller than or equal to the preset ratio, the second template is determined to be the display template corresponding to the target screen.

In particular, the aspect ratio of the target screen can represent a shape characteristic of the screen, such as being wider or square. Corresponding display templates may be determined according to different aspect ratios to determine templates more suitable for the target screen.

In such an embodiment, an appropriate display template may be selected according to the aspect ratio of the target screen so that the display effect more matches the screen when the content is displayed on the screen using the corresponding display template.

In addition, the first template and the second template are arranged in the embodiment of the application, the memory occupied by the two preset templates is small, and the template corresponding to the target screen can be rapidly determined in the memory, so that the screen throwing response speed is improved.

Optionally, the resolution of the first template is 1280×480; the resolution of the second template is 854 x 480. The resolution of the first template is suitable for a wider screen and the second template is suitable for a normal screen. When dividing the target screen by using the preset ratio, two types of screens can be obtained, wherein one type of wider screen can be used for applying the first template, and the other type of normal screen can be used for applying the second template.

In step 607, the transverse ratio and the longitudinal ratio are determined according to the resolution information of the target screen and the resolution information of the display template.

The resolution information may include two values, one is a horizontal resolution for indicating the number of pixels that can be displayed in the horizontal direction and the other is a vertical resolution for indicating the number of pixels that can be displayed in the vertical direction. The horizontal ratio may be determined using the number of pixels that the target screen can display in the horizontal direction and the number of pixels that the display template includes in the horizontal direction, and the vertical ratio may be determined using the number of pixels that the target screen can display in the vertical direction and the number of pixels that the display template includes in the vertical direction.

The ratio of the lateral resolution of the target screen to the lateral resolution of the display template can be determined as a lateral ratio; and determining the ratio of the longitudinal resolution of the target screen to the longitudinal resolution of the display template as a longitudinal ratio.

Further, if the display template corresponding to the target screen is the first template, determining a transverse ratio and a longitudinal ratio according to the resolution information of the target screen and the resolution information of the first template; and if the display template corresponding to the target screen is the second template, determining a transverse ratio and a longitudinal ratio according to the resolution information of the target screen and the resolution information of the second template. And the length-width relation between the target screen and the display template is determined through the transverse ratio and the longitudinal ratio, and the display template is adjusted based on the length-width relation, so that the adjusted template is more adaptive to the target screen.

Further, for example, the resolution information of the target screen is m×n, and the resolution of the display template corresponding to the target screen is m '×n', then the landscape ratio rW =m/m ', and the portrait ratio rh=n/n'.

The smaller of the lateral ratio and the longitudinal ratio is determined as the scaling, step 608.

In practice, the smaller of the transverse ratio and the longitudinal ratio may be determined as the scaling. The scale is used to adjust the display template.

Where rW is assumed to be smaller, the display template may be scaled using this scaling scale. For example, the display template may be scaled rW times. At this time, the size of the entire display template becomes: m is n 'x m/m'.

Specifically, if rW is smaller, it is indicated that the aspect ratio of the display template is larger than that of the target screen, and at this time, the long side of the display template can be preferentially adjusted to be consistent with the target screen, so that the display area of the target screen can be more fully utilized, and the content in the display template can be prevented from exceeding the display area of the target screen.

Further, if rH is smaller, it indicates that the aspect ratio of the target screen is larger than that of the display screen, and at this time, the wide side of the display template may be preferentially adjusted to be consistent with the target screen, so that the display area of the target screen may be more fully utilized, and the content in the display template may be prevented from exceeding the display area of the target screen.

In practical application, if the transverse ratio is equal to the longitudinal ratio, any one of the ratios can be used as a scaling ratio. In this case, the result is the same regardless of which ratio is used to scale the display template.

In the method provided in this embodiment, different adjustment manners and display manners are set for the first template and the second template, and reference may be made to steps 609A-610A and 609B-610B.

In step 609A, if the display template is the first template, the size of the fixed component, the size of the variable component, and the size of the fixed area in the first template are adjusted according to the scaling.

Wherein in the first template, a component for placing display content is defined as a variable component. The fixed component may be used to display fixed content such as page turning keys, labels, etc. The fixed and variable components may be sized using scaling.

In particular, the area between adjacent fixation elements may be defined as a fixation area. The size of the fixed area may be adjusted using a scaling.

Further, the distance between the variable component and the fixed component can be adjusted according to the actual condition of the target screen.

Specifically, the length and width of the fixed component, the variable component, and the fixed region may be adjusted according to the scaling, for example, the length and width of the component or the fixed region are multiplied by the scaling, so as to adjust the sizes of the component and the fixed region in the first template.

In this embodiment, the components and regions in the first template are processed at the same scaling, so that deformation or overlapping of the respective portions in the first template can be avoided, and the display effect can be improved.

Step 610A, setting the position of the fixed component at the peripheral position of the target screen; setting display content in the variable component, and setting the position of the variable component at the center position of the target screen; and determining the distance between the fixed component and the variable component according to the blank area remained in the target screen.

In practical application, when the electronic device sends display information to a target screen or a vehicle machine side, layout information can be sent. So that the target screen is displayed based on the layout information.

The layout information may include position information of each component. For example, the position information of the fixed component is set around the target screen, and the layout information of the variable component is located at the center of the target screen. The electronic device may also send the size of each component, the size of the fixed area, and in particular the size adjusted according to the scaling.

The layout information may further include that the distance between the fixed component and the variable component is adjusted along with the blank area actually remained in the target screen. For example, the blank area remaining in the target screen may be equally divided.

Specifically, the blank area refers to an area excluding the fixed component, the variable component, and the fixed area.

Fig. 7 is a schematic view of a display effect according to an exemplary embodiment of the present application.

As shown in fig. 7, when the display template corresponding to the target screen is the first template, the determined display effect is as shown in fig. 7.

In this way, the display content 71 can be centrally displayed, and the blank area is equally divided around the redisplay content 71, so that the display content 71 is more prominent. The key content is distinguished from the resident area, and the key content can play a role in highlighting key information. In addition, the pixel points can be reasonably split and utilized in the mode, and the suitability of display content is greatly improved.

In step 609B, if the display template is the second template, the size of the fixed component and the size of the component pitch in the second template are adjusted according to the scaling.

In the second template, components for placing contents such as display contents, page turning keys, labels and the like are defined as fixed components. The fixed component may be resized with a scaling.

In particular, the distance between adjacent fixed components is defined as the component pitch, which may include both lateral and longitudinal distances. The size of the component pitch may be adjusted using scaling.

Further, the size of the fixed component and the component spacing can be adjusted according to the scaling, for example, the component length and the component width are multiplied by the scaling respectively, and the size of the fixed component and the component spacing in the second template is adjusted by multiplying each component spacing by the scaling.

Step 610B, setting the display content in the first fixed component; and adjusting the size of the component spacing according to the blank area remained in the target screen.

The layout information may include position information of each fixed component. For example, the positional information of the fixed components may be determined based on the relative positions of the respective fixed components in the second template. For example, the fixing components for displaying the labels and the keys are arranged at the surrounding positions, and the first fixing component for displaying the content is arranged at the middle position. The electronic device may also send the size of each fixed component, the component pitch, and specifically the size adjusted according to the scaling.

The layout information may further include adjusting the component spacing according to the blank area actually remaining in the target screen, and specifically, the component spacing may be equally divided into the blank areas.

Specifically, the blank area refers to an area excluding the fixed component and the component pitch. The target screen can determine a blank area according to the display effect determined by the electronic equipment, and then adjust the component spacing according to the blank area.

Fig. 8 is a schematic view of a display effect shown in another exemplary embodiment of the present application.
