发明名称 Methods and apparatuses for controlling display refresh rate
摘要 A method and an apparatus for controlling a display refresh rate of a display device are provided. The control method comprises: obtaining a display parameter of current display content of the display device; determining, based on the display parameter, whether a reduction condition of a display refresh rate is met, so as to obtain a first determination result; controlling the display device to reduce the display refresh rate from a first display refresh rate to a second display refresh rate, when the first determination result indicates that the reduction condition of the display refresh rate is met. The above schemes may collect automatically the display parameter of the current display content of the display device, and determine, depending on the display parameter, whether the display refresh rate needs to be reduced. When it is determined that the display refresh rate needs to be reduced, the display refresh rate will be automatically reduced. All of the processes may be completed automatically without participation of the user. This may significantly improve flexibility of adjusting the display refresh rate.

主权项 1. A method of controlling a display refresh rate, comprising: obtaining a display parameter of current display content of the display device; determining, based on the display parameter, whether a reduction condition of a display refresh rate is met, so as to obtain a first determination result; the display parameter is a display duration of the current display content or variation amount between the current display content and content to be displayed by the display device; and when the display duration exceeds a first threshold, the first determination result indicates that the reduction condition of the display refresh rate is met; controlling the display device to reduce the display refresh rate from a first display refresh rate to a second display refresh rate, when the first determination result indicates that the reduction condition of the display refresh rate is met, comprising: determining the duration of the current display content;deciding refresh rate variation amount according to the duration;using a difference between the first display refresh rate and the display refresh rate variation amount as the second display refresh rate.
