Abstract
A display method and a display device are disclosed. The method includes: detecting whether a displayed content in a display screen changes; controlling the display screen to update alternately display data respectively corresponding to a first part and a second part of a display unit in each column of display unit, in response to detecting that the displayed content does not change. The number of updated pixels of the display screen each time may be reduced, while the original refresh frequency is maintained, so the problem that the splash screen phenomena is caused in the display screen by reducing the refresh frequency of the display screen may be solved, thus achieving effects of avoiding the splash screen phenomena of the display screen and of reducing the power consumption of the display screen while maintaining the original refresh frequency of the display screen.
