In step 204, the specific method for generating the second graphic data according to the data to be displayed refers to the method for generating the first graphic data according to the data to be displayed in the embodiment corresponding to fig. 1, which is not described herein again.
In the embodiment corresponding to fig. 2, the display control device determines to convert the data to be displayed into the first graphic data with the second resolution or the second graphic data with the first resolution according to the mode of the terminal, so that the processing complexity of the kernel data of the operating system can be reduced when the terminal is in the low-power mode, and the power consumption of the whole machine can be reduced under the condition of basically not influencing the system performance.
Referring to fig. 3, a method for displaying data on a screen according to an embodiment of the present invention has a resolution of a first resolution, and includes the steps of:
301. The display control means determines whether power consumption of one or more devices processing image display is greater than or equal to a preset value.
When the terminal processes the image display mainly through the GPU, the device for processing the image display here may be a CPU; when the terminal processes the image display mainly through the GPU, the device for processing the image display may be the GPU; of course, the device for processing the image display may also include a CPU, a GPU, and other devices related to image processing display.
302. When the power consumption of one or more devices for processing image display is greater than or equal to the preset value, the display control device generates first graphic data according to the data to be displayed.

Taking Android (Android) operation system of a mobile phone as an example, the method for displaying data on a screen according to the embodiment of the present invention is described with reference to the display control device provided by the foregoing embodiment, where the first resolution is 1080P, the second resolution is 720P, 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 are an Applications layer, a Framework layer, a library layer, and a Kernel layer, respectively.
The Kernel layer switching resolution is as follows: the current state operating system instructs the CPU (or CPU and GPU) to generate graphics data at 1080P resolution, and the operating system switches the CPU (or CPU and GPU) to generate image data at 720P resolution by setting an application; the following screens are all described by using an LCD (Liquid CRYSTAL DISPLAY ), and specifically, a control command may be written into a window MANAGER SERVICE (window management service) through an AM interface of a frame layer of an android system, where the control command may be an instruction for switching to an application low resolution, and the control command may be set to an instruction for switching to a low resolution to process data to be displayed, such as an instruction for playing a game low resolution, an ultralow power, and the like, according to different application scenarios. Of course, the switching process can be triggered by judging whether the mobile phone is in a low power consumption mode or not through the mobile phone operating system, or the switching process can be triggered by judging the power consumption of a device for processing image display through the operating system, for example, the operating system processes image display through the combination of a CPU and a GPU, when the power consumption of the CPU and the GPU for generating 1080P graphic data of data to be displayed is greater than or equal to a 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, namely, the CPU and the GPU generate 720P graphic data of the data to be displayed; the above process occurs mainly at the kernel layer of the operating system. The frame work layer switches the resolution, the operating system sets the resolution of the bottom layer of the system to 720P, then delivers the image frames of the 720P graphic data to the frame buffer (frame buffer) with the preset resolution through Surfaceflinger (Android display delivery module), the image frames are displayed on a display screen after the resolution is set in the frame buffer, in the invention, in order not to influence the display effect, when the image frames are in the frame buffer, a screen driving module amplifies the image frames from 720P to 1080P (namely, the resolution of the display data is converted from 720P to 1080P), the image frames are output to a 1080P screen, and the user display experience is not basically influenced (if the screen driving module does not support the amplification, the amplification can be realized by using image amplification algorithm software running in a CPU and/or a GPU, or the amplification can be realized through a display control circuit of a display providing a screen). Referring to fig. 6, an embodiment of the present invention provides a method for displaying data on a screen by Kernel interrupt, in which an operating system sets different resolutions on hardware by calling a frame buffer interface through a frame buffer driver at a Kernel layer, performs resolution switching by using parameters transmitted from upper layer application software, and a specific upper layer application software switching resolution function performs a state check on an LCD (in this embodiment, an LCD is illustrated as an example, it is understood that the present invention may also employ other types of display screens) by calling an int_check () function in the frame buffer driver, determining whether the LCD supports resolution switching, saving frame buffer information, and defining a flag bit for marking whether resolution switching can be performed; as shown in fig. 6, after an LDI (LAYERED DRIVER INTERFACE ) Frame end interrupt between image frames is used to trigger resolution switching, when a screen driving module detects the LDI Frame end interrupt, an interrupt processing function is invoked to obtain information in a flag bit, if the information in the flag bit indicates that resolution switching can be performed, an LDI parameter (including a resolution parameter of an operating system indicating process, such as 1080P or 720P, etc.) is set, at the same time, the screen driving module sets an EDC (ENHANCED DISPLAY Controller, an enhanced display Controller) to switch a display control parameter to a second resolution, and then the Android Surfaceflinger directs graphics data of 720P from a memory to EDC, G2D (Graphic of 2D, two-dimensional Graphic) is used to perform display processing, G3D (Graphic of3D, three-dimensional Graphic) is used to complete the display processing, and if the information in the flag bit indicates that resolution switching can be performed, the screen driving module outputs graphics data of 720P which completes the display processing to an LCD through DSI (DISPLAY SERIAL INTERFACE, a display serial interface) to the LCD, and in particular, since the graphics data of 720P which completes the display processing is cached in the Frame buffer is stored in the Frame and the display buffer 720P, graphics data of the Frame buffer 720P can be converted into graphics 720P through the display data which need to be read by the Frame driver 720P and the display processing circuit to realize graphics 720P.
Optionally, the screen driving module performs display processing on the 720P graphics data through EDC, G2D, and G3D, so that the conversion of the 720P graphics data into 1080P graphics data may be completed in the process of performing display processing on the 720P graphics data through EDC, G2D, and G3D.
Or amplifying the 720P graphic data by using image amplifying algorithm software operated by the CPU and/or the GPU to generate 1080P graphic data, and respectively importing the 1080P graphic data into EDC, G2D and G3D modules for display processing.
Here, since the resolution of the second resolution 720P graphics data is enlarged, the effect of full-screen display can be ensured, thereby ensuring user experience.
