In the mobile phone Android (Android) operating system as an example, in combination with the display control device provided by the above embodiment, the method for displaying data on the screen provided by the embodiment of the present invention is provided. The method is described, wherein the first resolution is 1080P and the second resolution is 720P. The current status screen displays data at a first resolution of 1080P.

Referring to Figures 5 and 6, the Android operating system includes: From the upper layer to the lower layer, respectively, the Applications layer, the Framework layer, the Libraries layer, and the Kernel layer.

The Kernel layer switching resolution is: 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 the application. The following screens are all described by LCD (Liquid Crystal Display). Specifically, the control commands can be written to the window manager service through the AM interface of the Android framework. The control command is OK. Switching to the application of low-resolution instructions, the control command can be set to switch to low-resolution processing of the data to be displayed, such as low-resolution, ultra-low power, etc., depending on the application scenario. Of course, the switching process can be triggered by the mobile phone operating system to determine whether the mobile phone is in a low power mode, or the switching process can also be triggered by the operating system to determine the power consumption of the device for processing the image display. For example, the operating system processes the image jointly by the CPU and the GPU. Display, when the CPU and GPU will generate data of 1080P to be displayed, the power consumption of the graphics data is greater than or equal to the preset value automatically triggers the switching process, the operating system switches the CPU (or CPU and GPU) resolution to 720P, ie the CPU and GPU will The data to be displayed generates 720P of graphics data; the above process mainly occurs in the kernel kernel layer of the operating system. The framework layer switches the resolution, the operating system sets the system's underlying resolution to 720P, and then delivers the image frame of the 720P graphics data to the frame buffer at a predetermined resolution through the Surfaceflinger (Android display delivery module), in the frame buffer. In the invention, the resolution is displayed on the display screen. In order to not affect the display effect, when the image frame is in the frame buffer, the screen driver module enlarges the image frame from 720P to 1080P (the resolution of the displayed data is converted from 720p). Up to 1080p), output to 1080P screen, basically does not affect the user display experience (if the screen driver module does not support zooming, you can use the image magnifying algorithm software running in the CPU and / or GPU to achieve magnification, or through the display of the display that provides the screen The control circuit achieves amplification). Referring to Figure 6, Embodiments of the present invention provide a way to display data on a screen through a kernel interrupt. The operating system sets a different resolution on the hardware through a frame buffer driver call frame buffer interface at the Kernel layer, and transmits it through the upper application software. The parameter is used for resolution switching. The specific upper-layer application software switching resolution function is used to call the LCD by using the int-check ( ) function in the frame buffer driver. (This embodiment uses an LCD as an example. It can be understood that the present invention can also be used. Other types of display) status check, determine whether the LCD supports resolution switching, save frame buffer information and define a flag to mark whether resolution switching can be performed; as shown in Figure 6, it can pass LDI between image frames (Layered Driver Interface) The frame end interrupt triggers the resolution switching. When the screen driver module detects the end of the LDI frame interrupt, it calls the interrupt handler to obtain the information in the flag. If the information in the flag indicates Perform resolution switching, then set LDI parameters (including operating system instructions) Resolution parameters such as 1080P or 720Ρ, and the ESD (Enhanced Display Controller) display control parameters are switched to the second resolution. Android Surfaceflinger takes 720P graphics data from the memory. Imported into EDC, G2D (Graphic of 2D, 2D Graphic), G3D (Graphic of 3D), display processing, display processing completed output to Frame buffer, screen driver module will complete the display processing 720P graphics The data is output to the LCD through the DSI (Display Serial Interface). Specifically, since the data of the 720P that completes the display processing is buffered in the Frame buffer, the LDI of the screen driver module needs to read the completion of the Frame buffer through the frame buffer driver. The processed 720P graphics data is displayed and output to the LCD through the DSI. For converting the graphics data of 720P to 1080P graphics data, the graphics data of 720P can be enlarged to 1080P graphics data through the display control circuit of the LCD.

Optionally, since the screen driving module performs display processing on the graphic data of 720P through EDC, G2D, and G3D, converting graphic data of 720P into graphic data of 1080P may also directly pass graphic data of EDC, G2D, G3D to 720P. This is done during the display process.

Or, the image magnification algorithm software running on the CPU and / or GPU will be 720P The graphics data is enlarged to generate 1080P graphics data, and the 1080P graphics data is separately imported into the EDC, G2D, and G3D modules for display processing. Here, since the resolution of the second resolution 720P graphic data is enlarged, the effect of full screen display can be ensured, thereby ensuring the user experience.
