Problems solved by technology

[0002] At present, with the development of the mobile industry, the development of the CPU (Central Processing Unit), the "heart" of the display terminal, has slowed down, and users have higher and higher requirements for the performance of the display terminal. Increased power, reduced battery life, power consumption and performance requirements have become one of the most concerned basic issues in the field of mobile terminals today
[0003] The inventor finds that no matter how much the utilization rate of the CPU of the display terminal is in the prior art, the processing frequency of its GPU (image processing unit) is a fixed value, so there are two problems: (1) if the CPU utilization rate is low, The data center reads that the user is currently in a static state (that is, in the mode of viewing pictures or browsing the webpage), and the running processing frequency of the GPU is relatively high, which not only fails to improve performance for the user, but also wastes energy consumption; if The CPU utilization rate is high, and the data center reads that the user is currently playing 3D online games. If the running processing frequency of the GPU is low, the image processing capability will be slow, and there will be problems with the mobile phone screen card, and the image processing is not smooth enough;

Embodiment 1

[0037] Such as figure 1 As shown, this embodiment provides an image display method, including the following steps:

[0038] judging the utilization rate of the central processing unit according to the pre-acquired working parameters of the central processing unit;

[0039] adjusting the processing frequency of the image processing unit according to the judgment result;

[0040] The display image resolution is adjusted according to the adjusted processing frequency of the image processing unit, so as to display the image.

[0041] In the image display method of this embodiment, the processing frequency of the image processing unit is adjusted according to the determined utilization rate of the central processing unit, so as to control the transmission speed of the image display data, and adjust the resolution of the displayed image, so that the display can be displayed in different In different working modes, different resolutions are used for image display, thereby reducing ...

Embodiment 2

[0043] Such as figure 2 As shown, this embodiment provides a method for displaying an image, which specifically includes the following steps:

[0044] Step 1. At the beginning, set the main frequency of the image processing unit of the display. That is, a reference processing frequency of the image processing unit is set.

[0045] Specifically, the display includes a clock unit, and the clock unit can provide a main frequency for the image processing unit.

[0046] Step 2, acquiring the working parameters of the central processing unit of the display. Wherein, the working parameters may be working parameters of the central processing unit including: working frequency.

[0047] Step 3. According to the working parameters of the central processing unit obtained in step 2, the utilization rate of the central processing unit is judged.

[0048] If the utilization rate of the central processing unit is determined in this step, the current state of the display used by the user ...

Embodiment 3

[0060] Such as image 3 As shown, this embodiment provides a display system that can display images by using the display method in Embodiment 1 or 2. The display system specifically includes: a judgment unit, a processing frequency adjustment unit, and a resolution adjustment unit; wherein, the judgment unit is used to judge the utilization rate of the central processing unit according to the pre-acquired working parameters of the central processing unit; the processing frequency adjustment The unit is configured to adjust the processing frequency of the image processing unit according to the judgment result of the judgment unit; the resolution adjustment unit is configured to adjust the display image resolution according to the adjusted processing frequency of the image processing unit.

[0061] In the display system of this embodiment, the processing frequency adjustment unit can adjust the processing frequency of the image processing unit according to the utilization rate o...
