Method for protecting oled screen, oled screen protecting system, and oled display

Abstract

A method for protecting an OLED screen, operated to protect a screen of an OLED display, is provided by the present disclosure. The method for protecting the OLED screen includes sampling a screen signal of the OLED screen (S101); detecting a change of the screen signal, when a period of the detected screen signal remaining unchanged or changing periodically in a first preset period is greater than a second preset period, output a control signal, in which the first preset period is greater than the second preset period (S102); and controlling the OLED screen to restart according to the control signal (S103), thus avoiding the situation that an image of the OLED screen is unchanged or periodically changed for a long time, solving the problem appearing an ghosting image on the OLED screen, without adding any hardware components and hardware circuits, and thereby reducing the cost.
