Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
In the conventional screen projection method, a terminal is usually connected to a display device for expansion in a wireless or wired manner, and application data on the terminal is output so that the display device can display the application data on the terminal.
When a display device (such as a projector or a liquid crystal display) is used as an extended screen, if the resolution or other display parameters of the display screen of a terminal (here, used as a data source output device) are different from those of another display device, situations such as incomplete display of application software, deviation of the position of functional display from normal situations, and the like are easily caused, thereby affecting the display effect of application data.
For example, if the resolution of the display screen of the terminal is 768P standard and the display specification of the display device is 2K standard, when the display device is used for connection, the application data output by the terminal may be displayed only on a small display area of the display device because the display specification of the display device is high, which affects the user experience.
And if the application data needs to be normally used, the common mode is to determine the default display parameters output by the terminal, and then manually adjust the relevant display parameters of the display device according to the display parameters, so that the application data can be normally displayed after the display parameters of the display device are matched with the display parameters of the application data. Therefore, the preparation workload of the user before the screen projection use is completed is large, and the use efficiency of the screen projection function is reduced.
In the present application, in order to solve the above problem, a display parameter adjustment method is adopted to solve the problem of low utilization efficiency of the screen projection function in the prior art.
The technical solution of the present application will be explained with reference to specific embodiments.
Referring to fig. 1, an application scenario of a display parameter adjustment method provided in an embodiment of the present application is shown in the figure.
As shown in fig. 1, the application scenario includes a data source output device 1, a display parameter adjustment device 2, and a display device 3.
The data source output apparatus 1 may be the terminal described above, and the terminal may be a smart phone, a personal computer, a handheld smart tablet, or other data source output devices that can be used to output application data. Specifically, the application data may be multimedia data downloaded or generated by an application program running in an operating system, such as an image, a video, a display interface of the application program, and the like, and the application does not limit a specific application data type.
The display device 3 may be a display for displaying application data, the display may be provided in a device for screen projection, or the device may be a device having a display function such as a television, a projector, or a personal computer.
This display parameter adjusting device 2 can be the equipment of being connected with data source output device 1, display device 3, and this display parameter adjusting device 2 can be through hardware interfaces such as HDMI, DVI or VGA, perhaps carries out the connection communication with data source output device 1, display device 3 through wireless networks such as WIFI.
It can be understood that, besides the above-mentioned specification of the transmission interface or the transmission protocol, data communication may also be performed through other common data transmission protocols/interfaces, such as an IP network interface, as long as data transmission between the display parameter adjusting device 2 and the data source output device 1 and the display device 3 can be realized, which is not described herein again.
Referring to fig. 2, an implementation flow of a display parameter adjustment method according to an embodiment of the present disclosure is shown in the figure.
As shown in fig. 2, the display parameter adjusting method may be applied to the display parameter adjusting apparatus shown in fig. 1, and may include the following implementation steps:
101. and acquiring display parameters of the data source output device and the display device.
The display parameter may refer to a video specification of application data of the data source output device, a preset data output specification, or refer to a display hardware specification of the display device, a preset data display specification, or the like. The display parameters may include at least one of a size parameter, a DPI parameter, and a resolution parameter.
For example, if the current display resolution of a certain television is 2K standard, the 2K display standard may be determined as the display parameter of the television. Of course, the display parameters should also be extended to the display scale, size parameters, DPI parameters, etc. of the tv, which are common display parameters.
For another example, in a smart phone that needs to be projected, if the video resolution of the currently output video (application data) is 1080P, the video resolution can be used as the display parameter. Or the display specification of the current display screen of the smart phone is used as the display parameter, and so on.
In an embodiment, the display parameters of the data source output device and the display device are obtained by combining the data transmission rules of the transmission protocol. For example, the EDID (Extended Display Identification Data) Data that the Data source output device and the Display device actively transmit to the Display parameter adjustment device, or the EDID Data that the Display parameter adjustment device actively acquires to the Data source output device and the Display device.
It can be understood that, in addition to the above-mentioned obtaining manner, the current display parameters of the data source output device and the display device may be obtained through other data related to the display parameters.
In an embodiment, the display parameters of the data source output device and the display device may be displayed, so that the user can confirm the display parameters of the data source output device and the display device respectively. Of course, the display parameters may also be displayed in a manner of audio broadcasting, indicator lights corresponding to different display parameters, and the like.
102. And receiving a format adjustment instruction for the display parameters, and acquiring corresponding adjustment information according to the format adjustment instruction.
The format adjustment instruction may be generated by the display parameter adjustment device according to a preset rule, or may be generated by another input module, for example, a button, a knob, or a touch screen is used to input a related format adjustment instruction.
In one embodiment, a knob having a plurality of gears may be employed to adjust or select the corresponding display parameter. For example, taking the display parameter as the display resolution as an example, the display parameter adjusting device is provided with a knob on a panel thereof, each gear of the knob corresponds to a common display resolution, and when a user operates the knob to rotate and select a gear, the corresponding target display resolution can be selected.
The corresponding adjustment information is obtained according to the format adjustment instruction, and the confirmation can be carried out by combining the mapping relation corresponding to the adjustment instructions in different formats and the adjustment information. For example, when the knob rotates two gears, the display parameter adjustment device can follow the format adjustment command generated by the knob to obtain the display resolution corresponding to the two gears.
103. And generating a control instruction based on the adjustment information.
The control instruction can be obtained by analyzing and reading by the display device or the data source output device, and corresponding control action is executed.
In one embodiment, the control instructions may be instructions of an EDID protocol. The EDID protocol can be conveniently read by the equipment and can enable the equipment to execute corresponding control instructions.
104. And sending the control instruction to a target device so that the target device adjusts the display parameters according to the format adjustment information corresponding to the received control instruction, wherein the target device comprises a data source output device and/or a display device.
The control command may be transmitted through a data line connected to the data source output device and/or the display device, such as HDMI, DVI, or the like.
After the target device receives the control instruction, the current display parameters can be adjusted according to the corresponding adjustment information in the control instruction, so that the display parameters of the target device are adjusted to be consistent with the display parameters of another device.
For example, if the display resolution of the display is 1080P, but the video format output by the data source output device is 2K standard, in order to correctly perform screen projection display, when the display resolution of the display needs to be adjusted to 2K, the display parameter adjustment device may be adjusted to generate corresponding adjustment information (the display resolution is adjusted to 2K standard), and a control command generated by the adjustment information is sent to the display, so that the display adjusts its display resolution to 2K standard according to the format corresponding to the received control command;
or adjusting the display resolution of the data source output device to 1080P to adapt to the display resolution of the display. At this time, the display parameter adjusting device can be adjusted to generate corresponding adjustment information (the display resolution of the data source is adjusted to 1080P standard), and a control instruction generated by the adjustment information is sent to the data source output device, so that the data source output device adjusts the display resolution of the data source to 1080P standard according to a format corresponding to the received control instruction and then outputs the adjusted data source (or selects other data sources with corresponding display resolution standards);
or, if the user actually wants to play the 4K video, but the display resolutions of the data source output device and the display do not meet the user requirement, the control instruction may be sent to the data source output device and the display at the same time, so that the display resolutions of the data source output device and the display are adjusted and matched at the same time to meet the user requirement.
The scheme enables the application data to be displayed on a screen correctly, so that the situations that the display of the application software is incomplete, the position of the function display deviates from the normal situation and the like are avoided.
As can be seen from the above, in the embodiment of the present application, the display parameters of the data source output device and the display device are automatically obtained, the received format adjustment instruction for adjusting the display parameters is generated into the corresponding control instruction and sent to the target device, and the display parameters of the target device are uniformly adjusted by using the display parameter adjustment method, so that the preparation workload before screen projection is used is reduced, and the screen projection use efficiency can be improved.
Referring to fig. 3, an implementation flow of generating a format adjustment instruction according to an embodiment of the present application is shown.
As shown in fig. 3, in an embodiment, the display parameter output by the data source output device may be a first display parameter, and the display parameter output by the display device may be a second display parameter;
in order to ensure the consistency of the display parameters between the data source output device and the display device, the display parameter adjusting method may also automatically complete the matching of the display parameters in the following manner.
After acquiring the display parameters of the data source output device and the display device, the method further comprises the following steps:
201. and judging whether the first display parameter is consistent with the second display parameter.
The first display parameter and the second display parameter are of the same parameter type. For example, if the first display parameter is the display resolution of the data source output device, the second display parameter is also the display resolution of the display device.
At this time, the display parameters of the same parameter type are compared to determine whether they are consistent.
202. And if not, generating a format adjusting instruction for instructing to adjust the second display parameter so as to adjust the second display parameter of the display device to be consistent with the first display parameter.
When the values of the first display parameter and the second display parameter are not consistent, if the display parameter of the display device needs to be adjusted, a format adjustment instruction for instructing to adjust the second display parameter may be generated.
203. And if not, generating a format adjusting instruction for indicating to adjust the first display parameter so as to adjust the first display parameter of the data source output device to be consistent with the second display parameter.
Of course, the determination of whether step 202 needs to be performed or step 203 needs to be performed may be determined according to actual situations. For example, if the display resolution of the display is 1080P, but the video format output by the data source output device is 2K standard, step 203 may be executed to adjust the video format of the data source output device to the 1080P format adapted to the display. Of course, if the display resolution of the display is too large or the display size is different from the display size of the data source output device, step 202 may be executed to make the display size of the display consistent with the display size of the data source output device.
Through the automatic comparison and generation of different format adjustment instructions, the display parameters of the corresponding equipment can be adjusted in a targeted manner, so that the display effect of the application data is ensured, and the display parameter adjustment device does not need manual intervention in an automatic comparison mode, so that the screen projection use efficiency is further improved.
With reference to fig. 4, another application scenario of the display parameter adjustment method provided in the embodiment of the present application is shown in the figure.
As shown in fig. 4, the application scenario includes a terminal, a display parameter adjusting device, and a display.
Wherein, the display parameter adjusting device executes the following steps:
301. and acquiring the display resolution output by the terminal and the display.
302. And displaying the acquired display resolution through the display screen.
The display parameter adjusting device can comprise a display screen, the display screen can obtain the display resolution output by the terminal and the display, and a user can conveniently obtain the display resolution currently set by the terminal and the display by watching the numerical value displayed by the display screen.
303. And receiving a format adjustment instruction generated by a user for screwing the knob, and acquiring corresponding adjustment information according to the format adjustment instruction.
Wherein, the knob can adopt only one, in order to adjust the target display parameter of terminal or display through the change over switch or other modes.
In one embodiment, two knobs may be used to control the display parameters of the terminal and the display, respectively.
It will be appreciated that input devices other than knobs, such as switches, touch modules, etc., may be used to effect manual adjustment of the display parameters.
304. And generating a control instruction conforming to the EDID protocol based on the adjustment information.
305. And sending a control instruction.
After the display obtains the control command sent by the display parameter adjusting device, by reading the control command, the following steps can be executed:
306. and adjusting the display resolution of the data source output device to be consistent with the display resolution of the display device.
The implementation principle is basically the same as that of a remote controller or other remote control modes, and specific implementation modes are not described in detail in the application.
By the method, the display parameter adjusting method can be more convenient for a user to adjust the display parameters of the terminal or the display, so that the parameter matching work required by screen projection can be quickly completed, and the use efficiency of the screen projection is improved.
