Problems solved by technology

However, in this state, since the display refresh rate is always maintained at the highest refresh rate state, and the higher the refresh rate, the higher the power consumption of the system, so the power consumption of the mobile terminal in this state is relatively high, resulting in battery life of the mobile terminal. Short battery life

Embodiment Construction

[0012] The present invention will be described in further detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0013] When using a mobile terminal, the application program can be divided into three categories according to the refresh rate requirements: the first category is 2D / 3D games, which have the highest requirements for the display refresh rate, and need to run at the highest display refresh rate to ensure smooth and responsive images. Timely; the second category is video, which has the second highest requirement for display refresh rate; the third category is general type applications, which do not have high requirements for display refresh rate, and running at a lower display refresh rate can ensure the screen application requirements. That is, for the latter two application scenarios, the system does not need to run at the highest refresh rate to meet the display requirements. For various types of application program...

Abstract

The invention discloses a control method and a control device of display refresh rate of a mobile terminal. The control method comprises the following steps: the first step is storing n range terminals defined in a load rate range between 0 and 100% of a central processing unit (CPU) of the mobile terminal, n display refresh rate values, and a correspondence table between the n range terminals and the n display refresh rate values, the second steps is detecting an average value of the load rate of the CPU within a preset time range when the mobile terminal runs, the third step is judging a range terminal to which the average value, detected in the second step, of the load rate of the CPU belongs, and the fourth step is obtaining a corresponding display refresh rate according to the range terminal to which the average value belongs in the third step and by inquiring the correspondence table in the first step, and using the corresponding display refresh rate as the refresh rate of a display of the mobile terminal. According to the control method and the control device of the display refresh rate of the mobile terminal, the display refresh rate of the display is adjusted according to the dynamic of the load rate of the CPU when the mobile terminal runs, using experience of a user is not affected and energy consumption of the system is reduced at the same time.

Description

technical field [0001] The present invention relates to a display refresh rate control method and device, in particular to a display refresh rate control method and control device of a mobile terminal. Background technique [0002] Mobile terminals, such as mobile phones and tablet computers, have become tools that people often use in their daily life and work. In order to ensure better user experience, the display refresh rate of the display screen of the mobile terminal is usually set to a fixed maximum refresh rate. When the mobile terminal is running in this state, no matter what application the user starts, the display can respond quickly and in a timely manner, so that the user can obtain a good experience when using the mobile terminal. However, in this state, since the display refresh rate is always maintained at the highest refresh rate state, and the higher the refresh rate, the higher the power consumption of the system, so the power consumption of the mobile ter...
