Abstract

Provided in an embodiment of the present invention are a screen power-saving mode display method, device and mobile terminal. In the power-saving mode, pixels contained in a screen have no more than one lit subpixel. The method comprises: acquiring a pixel corresponding to an element in an image displayed in a next frame of the screen; acquiring a color of a lit subpixel in each pixel corresponding to the element; counting the number of lit subpixels corresponding to each color; taking the color corresponding to the greatest number of lit subpixels as a first original color; setting the pixel corresponding to the first original color such that the element corresponding to the first original color is displayed with a first preset color in the next frame. The element is a word or an image. The electro-optical conversion efficiency of the subpixel corresponding to the first preset color is higher than the electro-optical conversion efficiency of the subpixel corresponding to the first original color. The present invention can further save power in a power-saving mode.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a display method, device and mobile terminal in a screen energy-saving mode. Background technique [0002] With users' preference for large screens of mobile terminals, the screens of mobile terminals are getting bigger and bigger. The problem that follows is that the power consumption of the screens is also getting higher and higher, resulting in weakened battery life of mobile terminals, making it difficult to satisfy users. demand. [0003] The power consumed by the screen is mainly used to maintain the display of the screen. A screen is usually composed of multiple pixels, and each pixel includes several sub-pixels. Depending on the type of screen, each pixel contains slightly different sub-pixels, which can be three or four. If there are three sub-pixels, they are green, red, and blue; if there are four sub-pixels, they are red, green, blue, and white. The graysca...
