Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a screen display method according to an embodiment of the present application, the method including the following steps:
and S101, monitoring the HDMI.
The HDMI (High Definition Multimedia Interface) is a fully digital video and audio transmission Interface, and can transmit uncompressed audio and video signals. The HDMI interface allows Hot-plugging (Hot-plugging or Hot Swap), i.e., hot-plugging, and the Hot-plugging function allows a user to plug in or plug out without shutting down the system or cutting off the power supply.
The HDMI interface is monitored, that is, whether the HDMI interface is plugged into a device or whether the plugged device is unplugged is monitored.
In the embodiment of the application, an original MIPI (Mobile Industry Processor Interface) display output scheme can be added with a conversion chip from hardware, so that HDMI output is increased. That is, in a specific embodiment of the present application, the step S101 of monitoring the HDMI interface includes: and monitoring the HDMI by using the conversion chip. Wherein, the conversion chip completes the conversion from MIPI to HDMI.
And S102, reading the screen display attribute after the HDMI hot plug event is detected.
The HDMI hot plug event comprises an HDMI hot plug event and an HDMI hot plug event, namely, the corresponding HDMI interface is plugged into or pulled out of the device.
In the embodiment of the application, different single-screen and double-screen output modes can be preset, different trigger conditions are set, and the output modes and the trigger conditions are written into the screen display attributes. That is, the screen display attribute specifies what output mode is to be handled in different cases. For example, after the HDMI is hot-unplugged, the output mode is single-screen output; after the HDMI hot plug, the input mode is double-screen output. Of course, the corresponding conditions of the specific output modes may be specifically set according to actual requirements, and are not listed here.
When there are different requirements for display, the connection or disconnection of the display device is often involved. For example, when dual-screen display is required, an external display screen is often required to be inserted; when the double-screen display is not needed, the external display screen can be pulled out. Therefore, in the embodiment of the present application, after the HDMI hot-plug event is detected, the screen display attribute can be read, so as to clarify the current output mode.
In a specific implementation manner in the present application, the single-screen display attribute and the dual-screen display attribute may also be adjusted, and the specific implementation process includes:
step one, receiving and analyzing a single-screen and double-screen output setting request to obtain single-screen and double-screen output setting;
and step two, modifying the screen display attribute according to the single-row and double-row output setting.
For convenience of description, the above two steps will be described in combination.
The screen display attributes may be modified by a single or double screen output setup request. Specifically, what kind of situation different output modes specifically correspond to can be indicated in the single-screen and double-screen output setting request; it is also possible to modify its corresponding trigger condition for the enablement of some output mode. Therefore, after the single-screen and double-screen output setting request is received, the single-screen and double-screen output setting can be obtained through analysis. Based on the single-screen and dual-screen output settings, the screen display output may be modified/updated. The specific setting or modification may be determined according to actual requirements, and will not be described herein.
Specifically, how to determine the current output mode, reference may be made to step S103.
And S103, switching the output modes of single and double screens by using the screen display attribute.
Since it is clearly specified what kind of output mode is used under what kind of condition in the screen display attribute, the current output mode can be determined based on the screen display attribute, that is, the switching of the output modes of single and double screens is completed. For example, at 8.
In a specific embodiment of the present application, the step S103 uses the screen display attribute to switch the output modes of the single screen and the double screens, including:
inquiring screen display attributes, and determining a target output mode hit by an HDMI hot plug event;
and step two, determining the target output mode as the current output mode.
For convenience of description, the above two steps will be described in combination.
That is, after the screen display attribute is read, the screen display attribute can be queried, so as to determine the target output mode hit by the HDMI hot-plug event.
The first step is to inquire the screen display attribute and determine the target output mode hit by the HDMI hot plug event, and the first step comprises the following steps:
case 1: if the HDMI hot plug event is the HDMI hot plug event, a double-screen output mode or an HDMI screen output mode in the screen display attribute is hit;
case 2: and if the HDMI hot plug event is the HDMI hot plug event, the single-screen output mode is hit.
For the above case 1, that is, when the HDMI hot plug event is detected, the HDMI hot plug event may hit the dual panel output mode or the HDMI panel output mode. That is, for the HDMI hot-plug event, the dual screen output mode or the HDMI screen output mode may be set in the screen display attribute correspondingly.
For case 2 above, i.e., when an HDMI hot-unplug event is detected, the HDMI hot-unplug event may hit the single-screen output mode. That is, for an HDMI hot-unplug event, a single screen output mode may be correspondingly set in the screen display attribute.
After the target output mode is determined, the target output mode can be directly determined as the current output mode. It should be noted that, in the present application, the target output manner may be the same as the current output manner before the target output manner is not determined as the current output manner. That is, the display output mode may be the same before the HDMI hot plug event is detected and after the HDMI hot plug event triggers the single-screen display and the dual-screen display to switch. That is, by setting the screen display attribute, the HDMI hot-plug event can be made not to affect the specific display output manner.
And S104, outputting the video signal to a target screen corresponding to the current output mode.
After the current output mode is determined, the video signal can be output to the target screen corresponding to the current output mode.
That is, to which screen the current output mode corresponds, the video signal is output to which screen. Note that when the two-screen output is performed, the video signals output to the two screens may be the same or different. That is, when the two-screen display is performed, the two screens may display the same content or different content.
In a specific embodiment of the present application, the step S104 of outputting the video signal to the target screen corresponding to the current output mode includes:
step one, determining a target screen corresponding to a current output mode;
and step two, outputting the video signal to the target screen by using the output channel corresponding to the target screen.
For convenience of description, the above two steps will be described in combination.
Firstly, a target screen corresponding to the current output mode is determined. For example, when the device is in a dual-screen output mode, two corresponding target screens exist, one is a display screen of the device/terminal, and the other is an external display screen; if the single-screen output mode is adopted, the corresponding target screen is 1, and at this time, the target screen may be a display screen of the device/terminal itself or an external display screen, and a specific target screen may be undetermined according to the setting. For example, the single-screen output can be divided into an HDMI single-screen output mode (or an external single-screen output mode), and an MIPI single-screen output mode (or a local single-screen output mode), so that which target screen is can be determined only by which single-screen output is specific.
In a specific embodiment of the present application, the step S104 of outputting a video signal to a target screen corresponding to the current output mode includes:
step one, if the target screen is a screen in the HDMI equipment, converting a video signal into an HDMI signal by using a conversion chip;
and step two, sending the HDMI signal to an HDMI interface of the HDMI equipment.
For convenience of description, the above two steps will be described in combination.
That is to say, when it is determined that the target screen is the screen in the HDMI device, the conversion chip may be used to convert the video signal into the HDMI signal, and then send the HDMI signal to the HDMI interface of the HDMI device, so that the screen in the HDMI device may display the content based on the received signal.
The method provided by the embodiment of the application is applied to monitor the HDMI; after detecting the HDMI hot plug event, reading the screen display attribute; switching the output modes of single and double screens by using the screen display attribute; and outputting the video signal to a target screen corresponding to the current output mode.
In the application, the HDMI is monitored, and because the HDMI allows hot plug, when an HDMI hot plug event is detected, the screen display attribute can be read, and the output modes of the single screen and the double screens are switched by using the screen display attribute. And then, outputting the video signal to a target screen corresponding to the current output mode. That is to say, in the present application, the triggering of switching the output mode of the single screen and the dual screens is based on the HDMI hot-plug event corresponding to the HDMI interface, and after the current output mode is determined, the video signal is transmitted to the target screen. Namely, the single-screen and double-screen display mode can be freely switched under the condition of not depending on a double-screen display frame through a hardware triggering condition, so that the switching freedom of single-screen and double-screen display is realized, the problem of frame rate transmission speed reduction due to the dependence on the double-screen display frame can be solved, and the consumption problems of excessive GPU and system resources and power consumption when only a single screen is accessed can be solved.
In order to make those skilled in the art better understand and implement the screen display method provided in the embodiments of the present application, the screen display method is described in detail below with reference to a specific application scenario as an example.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating an implementation of a screen display method according to an embodiment of the present application.
The original MIPI display (hot plug is not supported) output scheme is added with a conversion chip from hardware, so that HDMI output is increased. And the double-screen display function is modified, and single-screen and double-screen switching can be performed through the configurable attribute of the system. By acquiring the system event of inserting and pulling out the HDMI equipment, the dynamic setting of the configurable attribute of the system is realized, and thus the dynamic switching scheme of single-screen and double-screen display is realized.
In fig. 2, the system layer listener: the system is used for monitoring HDMI peripheral plugging events reported by a bottom layer and modifying system configuration attributes; HAL layer single-double screen display SO library: the SO library file for actually controlling the display logic has the main function of switching between single-screen display and double-screen display according to the configuration attribute of the system; MIPI output channel: a data information transmission interface of the hardware display device; MIPI changes HDMI control IC: the control IC circuit converts the MIPI output signal into an HDMI output signal; HDMI interface and screen: a plug-and-play display output interface.
Therefore, the terminal can freely switch the single-screen display mode and the double-screen display mode through the hardware triggering condition. The scheme can realize single-screen display scene and completely strip the double-screen display frame, and the problem of frame rate transmission speed reduction caused by double-screen display is solved. The consumption of excessive GPU and system resources and power consumption when only a single screen is accessed under the condition that firmware is not modified (double-screen display) can be avoided. Software setting is added, and a single-screen and double-screen scheme can be manually switched; when the hardware triggers the dynamic switching of the single screen and the double screens, the display function takes effect immediately, and simultaneously, the display function still takes effect after the restart.
The following explains the effect of the screen display method with reference to actual requirements:
example 1: the mobile terminal equipment manufactured by using the module based on the Android system only has single-screen display requirements during daily operation of the equipment, but needs to be externally connected with HDMI display equipment to perform a multi-party demonstration function in scenes such as extended demonstration and the like. By applying the screen display method provided by the embodiment of the application to the mobile terminal device, the device can be displayed on a single screen only during daily operation, and the external HDMI display device can be used for multi-party demonstration in scenes such as extended demonstration.
Example 2: for any single-screen display device based on the Android system, after the screen display method provided by the embodiment of the application is applied, dynamic expansion support of the HDMI display is carried out. Different MIPI devices are supported without modifying software and firmware, and compatibility is stronger.
Example 3: after the aircraft controller manufactured by using the Android system-based module is applied to the screen display method provided by the embodiment of the application, the performance of image transmission, display and the like is optimized under the condition of supporting the firmware of double-screen display, and the problem of blockage is solved.
Therefore, the screen display method provided by the embodiment of the application is based on a display frame of an Android system, double-screen display is realized by depending on expansion of bottom layer output, and the problems that a MIPI (million instructions and interfaces) interface cannot be hot plugged and unplugged and single-double-screen display cannot be dynamically switched are solved by the plug-and-play function of HDMI (high-definition multimedia interface) hardware and the capacity of plugging and unplugging trigger events. The double-screen display can be applied to more scenes, such as scenes that single-screen and double-screen display switching control is needed, and HDMI interface output display is needed to be connected under specific conditions; and for double-screen software, system optimization is carried out when only a single screen is available.
