Abstract: A display method applied to an electronic device, a graphical user interface, and an electronic device are provided. The electronic device may perform, based on a most power saving display color of a display, color transformation on an interface element to be displayed on the display, so as to change a color of the interface element to be displayed on the display, thereby reducing power consumption of the display. In addition, in a color transformation process, color fidelity is performed on (in other words, no color transformation is performed on) an interface element that includes rich information (for example, rich colors), so that rich meanings represented by the interface element can be preserved.

Abstract: The present disclosure provides example methods for changing graphics processing resolution according to a scenario. In one example, a first display scenario is determined as a scenario in which energy can be saved. Based on the determination, a graphics processing resolution of a graphics processor can be reduced. At least one target graphics frame in the first display scenario can be rendered by the graphics processor according to the reduced graphics processing resolution to obtain at least one target image frame. The at least one target image frame can be adapted according to screen display resolution, and the at least one adapted target image frame can be displayed. The present disclosure further provides a portable electronic device and a system for changing graphics processing resolution according to a scenario.

Abstract: The present disclosure relates to example processing methods and devices. In one example method, resolution of each layer of multiple layers of an application program are determined. Resolution of a first layer is lower than resolution of another layer. The multiple layers are created according to the resolution of each layer. Rendering processing is performed on the multiple layers. Scaling processing is performed on a second layer obtained after the rendering processing. The determined resolution of the second layer is different from resolution of a preset area displaying the second layer on a display screen. Resolution of the second layer obtained after the scaling processing is the same as the resolution of the preset area. A layer other than the second layer obtained after the rendering processing is composited with the second layer obtained after the scaling processing. An image obtained after the composition is output to the display screen.

Abstract: A display method of a terminal device and a terminal device is provided. The display method of a terminal device includes: a framework layer sends a first touch point data; an application layer sends instruction information used to instruct to transfer slide drawing control rights to the framework layer and a generated display list to the framework layer after the application layer determines that the terminal device enters a sliding state according to acquired first touch point data; and the framework layer acquires second touch point data from a shared memory according to the instruction information, and draws an image according to the second touch point data and the display list. In this way, in an operation with repetitive image composition, the slide drawing control rights are transferred from an application module to a framework module, improving a response speed of a terminal system.
