The display control apparatus provided by the embodiment of the present invention generates first graphic data of a second resolution according to data to be displayed; the resolution of the first graphic data is converted into a first resolution and then output to a screen for display, wherein the first resolution is greater than a second resolution, and the data to be displayed is processed with the second resolution when the first graphic data is generated, so that the processing complexity of the kernel data of an operating system can be reduced, the power consumption of the whole machine is reduced under the condition that the system performance is not influenced basically, and in addition, the bandwidth occupancy rate of each component of the kernel can also be reduced due to the reduction of the resolution of the kernel processing data.
Taking the Android operating system of the mobile phone as an example, the method for displaying data on a screen provided by the embodiment of the invention is described with reference to the display control device provided by the above embodiment, where the first resolution is 1080P, the second resolution is 720P as an example, and the current status screen displays data with the first resolution being 1080P.
Referring to fig. 5 and 6, the Android operating system includes: from the upper layer to the lower layer, Applications, Framework, Libraries, and Kernel are respectively provided.
Wherein the Kernel layer switching resolution is: the current state operating system instructs the CPU (or the CPU and the GPU) to generate graphic data at a resolution of 1080P, and the operating system switches the CPU (or the CPU and the GPU) to generate image data at a resolution of 720P through a setting application; the following screens are all described by using an LCD (Liquid Crystal Display), specifically, a control command may be written into a window manager service (window management service) through an AM interface of a frame layer of the android system, where the control command is an instruction that can be switched to application low resolution, and the control command may be set to an instruction that switches to low resolution to process data to be displayed, such as an instruction of game low resolution, ultra-low power, and the like, according to different application scenarios. Certainly, the switching process may be triggered by determining whether the mobile phone is in the low power consumption mode by the mobile phone operating system, or the switching process may be triggered by determining the power consumption of the device for processing the image display by the operating system, for example, the operating system processes the image display by combining the CPU and the GPU, and when the power consumption of the 1080P graphics data generated by the CPU and the GPU is greater than or equal to the preset value, the switching process is automatically triggered, and the operating system switches the resolution of the CPU (or the CPU and the GPU) to 720P, that is, the CPU and the GPU generate the 720P graphics data from the data to be displayed; the above process mainly occurs in the kernel layer of the operating system. The resolution of a frame layer is switched, an operating system sets the resolution of a system bottom layer to be 720P, then an image frame of graphics data of 720P is delivered to a frame buffer (frame buffer) through a SurfaceFlinger (Android display delivery module) at a preset resolution, the image frame is displayed on a display screen after the resolution is set in the frame buffer, in order to not affect the display effect in the invention, when the image frame is in the frame buffer, a screen driving module amplifies the image frame from 720P to 1080P (namely, the resolution of the display data is converted from 720P to 1080P), and the amplified image is output to a 1080P screen, and the user display experience is not affected basically (if the screen driving module does not support the amplification, the amplification can be realized by image amplification algorithm software running in a CPU and/or a GPU, or the amplification can be realized by a display control circuit of a display providing the screen). Referring to fig. 6, an embodiment of the present invention provides a manner of displaying data on a screen through Kernel interrupt, where an operating system sets different resolutions on hardware through a frame cache driver calling a frame cache interface at a Kernel layer, performs resolution switching through parameters passed by upper layer application software, and a specific upper layer application software switching resolution function performs state check on an LCD (in this embodiment, the LCD is taken as an example for explanation, it is understood that the present invention may also be applied to other types of display screens) by calling an int _ check () function in the frame cache driver, to determine whether the LCD supports resolution switching, save frame cache information, and define a flag bit for marking whether resolution switching can be performed; as shown in fig. 6, resolution switching may be triggered by a Layer Driver Interface (LDI) Frame ending interrupt between image frames, when the screen Driver module detects the LDI Frame ending interrupt, an interrupt handling function is called to obtain information in a flag bit, if the information in the flag bit indicates that resolution switching may be performed, LDI parameters (including resolution parameters that an operating system indicates to perform processing, such as 1080P or 720P, etc.) are set, and after the screen Driver module sets an Enhanced Display Controller (EDC) Display control parameter to switch to a second resolution, a surfflex of Android module imports the 720P graphics data from a memory into the EDC, a G2D (graphics of 2D, two-dimensional diagram), a G3D (graphics of3D, three-dimensional diagram) module performs Display processing, the Display processing is completed and output to a Frame buffer, the screen Driver module outputs the 720P graphics data that has been completed Display processing through a DSI (Display Interface, display serial interface) to the LCD, specifically, since 720P data completing display processing is buffered in the Frame buffer, the LDI of the screen driving module needs to read 720P graphics data completing display processing in the Frame buffer through Frame buffer driving and output the data to the LCD through DSI, and for converting the 720P graphics data into 1080P graphics data, the display control circuit of the LCD may implement enlarging the 720P graphics data into 1080P graphics data.
Optionally, since the screen driving module performs display processing on the 720P graphics data through the EDC, G2D, G3D, the conversion of the 720P graphics data into 1080P graphics data may also be completed in the process of performing display processing on the 720P graphics data through the EDC, G2D, G3D directly.
Alternatively, the image enlargement algorithm software run by the CPU and/or the GPU enlarges the 720P graphics data to generate 1080P graphics data, and then introduces the 1080P graphics data into the EDC, G2D, and G3D modules, respectively, for display processing.
Since the resolution amplification is performed on the 720P second-resolution graphic data, the full-screen display effect can be ensured, and the user experience is ensured.
