Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data display processing method provided by the application can be applied to the application environment shown in fig. 1. The terminal 102 includes a display device 104, and the terminal 102 obtains a resolution switching request, where the resolution switching request carries a current resolution and a target resolution of the display device. The terminal 102 adjusts a frame buffer corresponding to the display device, a current display area size of the display device 104, and a current screen density according to the resolution switching request, so as to obtain an adjusted frame buffer and an adjusted display device 104. The terminal 102 switches the current resolution to the target resolution according to the resolution switching request. And the terminal 102 adjusts the display data in the adjusted frame buffer according to the target resolution in the resolution switching process. After the resolution switching is completed, the terminal 102 displays the adjusted display data on the display device 104 after the resolution switching. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers. The display device 104 may be a display screen on the terminal 102 on which content may be displayed.
In one embodiment, as shown in fig. 2, a data display processing method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:
When the terminal is started, the display configuration information of the registered display equipment is traversed. The display configuration information may include information such as screen width, screen length, screen density, resolution, and the like. Whether the terminal supports a plurality of resolutions is identified in the display configuration information of the registered display device. The resolution is the number of pixel points in the horizontal and vertical directions, and the unit is px, and 1px represents 1 pixel point. The resolution may be expressed by the product of the number of vertical pixels and the number of horizontal pixels. For example 1920px 1080 px. When the terminal supports a plurality of resolutions, it is possible to switch between the resolutions. For example, the terminal may support two resolutions, QHD + (Quarter of Quarter High Definition, FHD 1920 x 1080) and FHD + (Full High Definition, Full 1920 x 1080). After the terminal is started, the current resolution can be determined in a plurality of resolutions according to preset configuration information. The terminal can display the data to be displayed in the display device according to the current resolution. When the terminal acquires the resolution switching request, the resolution switching request is analyzed, and the current resolution and the target resolution of the display device are obtained. The target resolution is the resolution that needs to be switched. The target resolution may be greater than the current resolution or less than the current resolution. For example, when the terminal is low in power or needs to save power, the target resolution may be smaller than the current resolution to save power consumption. As another example, when the terminal needs to improve the definition of the screen, the target resolution may be greater than the current resolution.
And step 204, adjusting the frame buffer corresponding to the display device, the current display area size of the display device and the current screen density according to the resolution switching request to obtain the adjusted frame buffer and the adjusted display device.
And the terminal calls a preset thread according to the resolution switching request. The default thread may be a surfaceflinger. And adjusting a frame buffer (frame buffer) corresponding to the display device through a preset thread. Meanwhile, the current display area and the current screen density of the display device are adjusted through a preset thread, and therefore an adjusted frame buffer area and an adjusted display device are obtained. One display device may correspond to one frame buffer. The frame buffer is a two-dimensional array of pixels, located in kernel space. Each storage unit in the frame buffer may correspond to a pixel on a screen of the display device, and the data to be displayed in the entire frame buffer may correspond to a frame of image, i.e., a screen image displayed on the display device. The frame buffer is used for storing data to be displayed and providing data to be displayed to the display device. The current display area may be a display scale of the original data to be displayed corresponding to an area where the displayed data is located. Screen density refers to the number of pixels per inch.
And step 206, switching the current resolution to the target resolution according to the resolution switching request.
And step 208, in the resolution switching process, adjusting the display data in the adjusted frame buffer according to the target resolution.
And step 210, after the resolution switching is completed, displaying the adjusted display data in the display device after the resolution switching.
After the terminal adjusts the frame buffer corresponding to the display device, the current display area size of the display device and the current screen density, resolution switching can be performed according to the resolution switching request, and the terminal switches the current resolution to the target resolution.
In the process of switching the resolution, the terminal needs to adjust the display data in the adjusted frame buffer according to the target resolution because the resolution is changed. Specifically, the terminal calculates a ratio between the target resolution and the current resolution as a scaling parameter. And correspondingly zooming the display data in the adjusted frame buffer area according to the zooming parameters.
And after the resolution switching is finished, rendering the zoomed display data in the switched display equipment again to obtain a rendered interface.
In this embodiment, the frame buffer corresponding to the display device, the current display area size of the display device, and the current screen density are adjusted according to the resolution switching request, so as to obtain the adjusted frame buffer and the adjusted display device. And switching the current resolution to the target resolution according to the resolution switching request. And in the resolution switching process, adjusting the display data in the adjusted frame buffer area according to the target resolution. And after the resolution switching is finished, displaying the adjusted display data in the display equipment after the resolution switching. When the resolution ratio is switched, hardware does not need to be replaced, and the subsequent resolution ratio switching can be realized only by adjusting a frame buffer area corresponding to the display equipment, the current display area of the display equipment and the current screen density, so that the display data is adjusted to be displayed according to the target resolution ratio in the resolution ratio switching process. The service cost of the terminal can be effectively reduced.
In one embodiment, as shown in fig. 3, the step of adjusting the frame buffer of the display device, the current display area of the display device and the current screen density according to the resolution switching request comprises:
And step 304, adjusting a frame buffer of the display device according to the target resolution through the first interface.
And step 306, adjusting the current display area and the current screen density of the display device through the second interface according to the target resolution and the current resolution.
And the terminal calls a preset thread according to the resolution switching request. The default thread may be a surfaceflinger. And calling the first interface and the second interface in parallel through a preset thread. For example, the first interface may be a HWComposer interface. And adjusting a frame buffer area of the display device through the first interface. Specifically, the resolution of the frame buffer area is adjusted through the first interface, and the resolution of the frame buffer area is adjusted to the target resolution. The number of pixel points of display data in the display equipment is limited by the frame buffer, so that the number of the pixel points can be used as the resolution of the frame buffer, and the subsequent resolution switching is facilitated. And the terminal adjusts the current display area and the current screen density of the display equipment through the second interface to obtain the size of the display area and the screen density corresponding to the target resolution.
In this embodiment, the first interface and the second interface are called in parallel according to the resolution switching request, so that the frame buffer of the display device can be adjusted at the same time, and the current display area and the current screen density of the display device can be adjusted. The switching efficiency of the resolution ratio is improved.
In one embodiment, adjusting a frame buffer of a display device according to a target resolution through a first interface comprises: acquiring the resolution of a frame buffer area of the display equipment through a first interface; the resolution of the frame buffer is adjusted to the target resolution.
And the terminal adjusts the frame buffer area through the first interface. The size of the frame buffer may indicate the storage resolution. The number of pixel points of display data in the display equipment is limited by the frame buffer, so that the number of the pixel points can be used as the resolution of the frame buffer, and the subsequent resolution switching is facilitated.
The frame buffer is adjusted through the first interface, i.e. the resolution of the frame buffer is adjusted. And acquiring the resolution of a frame buffer area of the display device through the first interface, and switching the resolution to the target resolution. Specifically, the historical data stored in the frame buffer area is emptied through the first interface, the resolution of the emptied frame buffer area is switched according to the target resolution, and the resource identifier of the frame buffer area after resolution switching is updated, so that the frame buffer area is identified or modified through the resource identifier in the following process.
In this embodiment, by switching the resolution of the frame buffer, the data to be displayed can be displayed in a point-to-point manner during the resolution switching process.
In one embodiment, adjusting, via the second interface, the current display area and the current screen density of the display device according to the target resolution includes: determining the size of a target display area of the display equipment according to the target resolution through a second interface; and adjusting the current display area according to the size of the target display area, and adjusting the current screen density of the display equipment to the target screen density corresponding to the target resolution.
Due to the switching of the resolution, the display area of the display device may change accordingly. Therefore, the size of the display area needs to be configured according to the target resolution to meet the target resolution, so as to ensure normal display of the display data. And acquiring the size of the current display area of the display equipment under the current resolution through the second interface, and determining the size of the target display area of the display equipment according to the target resolution. And calculating the ratio of the size of the target display area to the size of the current display area, taking the ratio as a scaling ratio, and scaling the current display area according to the scaling ratio.
The screen density refers to the number of pixels per inch in dpi. Screen density is related to screen size and resolution. The resolution may be expressed by the product of the number of vertical pixels and the number of horizontal pixels. The screen density is calculated by the formula:
according to the calculation formula, when the screen size is unchanged, the higher the resolution is, the higher the screen density is; when the resolution is unchanged, the smaller the screen size, the greater the screen density.
The terminal can acquire the current resolution and the current screen density through the second interface, and when the size of the screen is fixed, the target screen density corresponding to the target resolution can be calculated according to the proportional relation between the resolution and the screen density. And then switching the target screen density to the current screen density.
In this embodiment, the size of the target display area of the display device is determined according to the target resolution through the second interface, so that the current display area is adjusted according to the size of the target display area, and the current screen density of the display device is adjusted to the target screen density corresponding to the target resolution. The size of the display area and the screen density can be ensured to be adaptive to the target resolution.
In one embodiment, the method further comprises: in the resolution switching process, calling a transition layer through a resolution switching request, and covering the zooming process of the display data through the transition layer; and when the resolution switching is completed, hiding the transition layer.
In the process that the current resolution is switched to the target resolution by the terminal, a screen display interface of the display device is in a zooming state. To mask this scaling state, the transition layer may be invoked by a resolution switch request. The transition layer may be a scenschotsurface. The transition layer is overlaid on a zoom layer of the display data. When the resolution is switched from high resolution to low resolution, the transition layer can be enlarged; when the resolution is switched from low resolution to high resolution, the transition layer can be reduced. Since the transition layer is scaled up or down in the GPU composition. Therefore, the GPU composition needs to be run all the time during the resolution switching. And when the resolution switching is finished, hiding the transition layer, namely finishing the calling of the transition layer.
In this embodiment, the transition layer is used to cover the scaling process of the display data, so as to optimize the switching effect of the resolution, and enable the user to switch the resolution without being aware of the switching effect.
In one embodiment, before acquiring the resolution switching request, the method further includes: traversing and displaying configuration information; acquiring a plurality of resolutions corresponding to the display equipment in the display configuration information; determining a current resolution of the display device among the plurality of resolutions according to preset configuration information.
When the terminal is started, i.e. powered on, a class is created that displays management services. The global display state is handled by the display management service. The terminal registers all the display devices. The display devices may include a main display device and a virtual display device. For example, the virtual display device may be a device in which the terminal projects display data onto a television screen through a network, and the television screen may be a virtual display device. The terminal traverses the display configuration information of each display device. The display configuration information may include information such as screen width, screen length, screen density, resolution, and the like. And determining a plurality of resolutions corresponding to the display equipment in the display configuration information. And then determining the current resolution of the display device in the plurality of resolutions according to the preset configuration information. The preset configuration information may include a default resolution preset by a system administrator. And the terminal displays data on the display equipment according to the default resolution. When a resolution obtaining request is obtained, the default resolution is used as the current resolution, and the resolution obtaining request also carries the selected target resolution.
In the process of acquiring the resolution, the terminal may perform processing according to the following logical relationship. Specifically, when the terminal is started, i.e., turned on, it creates (new) a class of displaymanager service () and processes the message in the register defaultdisplayadapters ().
Then, the terminal may register all display devices in the register defaultdisplayadapters (), obtain display configuration information, and provide corresponding display adapters for the registered display devices through the local displayadapters, so as to manage the display devices through the display adapters. The display device may include a main display device and a virtual display device. For example, the virtual display device may be a device in which the terminal projects display data onto a television screen through a network, and the television screen may be a virtual display device.
The terminal sends getDisplayConfigs () with getActiveConfig () to SurfaceControl through LocalDisplayAdapters. Therefore, a display configuration information acquisition request SurfaceFliner is sent through SurfaceControl, display configuration information is acquired in the SurfaceFliner, and then a plurality of resolutions and refresh rates corresponding to the display equipment are determined in the display configuration information. For example, when the display device supports two resolutions of QHD + (Quarter High Definition, FHD 1920 × 1080) and FHD + (Full High Definition, Full High Definition 1920 × 1080) and two refresh rates of 120fps and 60fps, the display configuration policy (DisplayConfig) of the display device acquired by the terminal may include: QHD +/120fps, QHD +/60fps, FHD +/120fps, and FHD +/60 fps. The display configuration policy (DisplayConfig) may further include information such as a screen density (density), a screen width (width), a screen height (height), the number of pixel dots (xdpi) held one inch in the horizontal direction, the number of pixel dots (ydpi) held one inch in the vertical direction, and the like.
In this embodiment, the resolution is obtained by traversing the display configuration information of the display device, and the current resolution is determined according to the configuration information, so as to implement automatic configuration of the current resolution.
In one embodiment, the method further comprises: receiving a default setting operation of a target resolution; and after the terminal is closed, when the terminal is restarted, identifying default setting operation, and displaying the default resolution of the target resolution on the equipment according to the default setting operation.
The terminal can receive the default setting operation of the target resolution, set the switched target resolution as the default resolution and store the target resolution. And after the terminal is closed and is started again, the terminal can identify the default setting operation and analyze the default setting operation to obtain the target resolution. And then the target resolution is used as the default resolution of the display device.
In this embodiment, by receiving the default setting operation of the target resolution, when the terminal is turned off and then is turned on again, the default setting operation may be recognized, and the default resolution of the target resolution is displayed according to the default setting operation. The resolution ratio can be automatically set, the resolution ratio does not need to be frequently switched, and the service efficiency of the terminal is improved.
