Abstract

The invention provides a method and apparatus for adjusting screen refreshing frequency, and a display. The method comprises the following steps: obtaining and storing a current-frame image signal; calculating a similarity value between the current-frame image signal and a previous-frame image signal; and based on the similarity value, according to a preset relation between a similarity value and a screen refreshing frequency, obtaining the screen refreshing frequency for the current-frame image signal. According to the invention, the screen refreshing frequency becomes adjustable, power consumption of a display device can be effectively reduced, and this has a great promotion effect on improvement of quality and competitiveness of a display product.

Description

technical field [0001] The present invention relates to the field of screen display, more specifically, to a method for adjusting the screen refresh rate, a device for adjusting the screen refresh rate, and a display. Background technique [0002] With the advancement of display technology, users have higher and higher requirements on the quality of images displayed by display devices. Generally, the higher the picture quality of the display device (that is, the clearer the picture), the higher the screen refresh rate. However, a high screen refresh rate will inevitably lead to an increase in power consumption. [0003] Therefore, high-quality images and low power consumption are a contradiction to be resolved in the display field. The traditional approach often takes care of one thing at the expense of another, or pursues high picture quality and generates greater power consumption; or sacrifices picture quality in order to reduce power consumption. There is rarely a goo...
