Problems solved by technology

[0002] The current OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has the problem of brightness attenuation
Moreover, due to the display content, the brightness attenuation of the always bright place is large, often leaving afterimages, commonly known as "burn-in", which has become a defect of OLED displays
In order to solve the problem of OLED brightness attenuation, many solutions have been proposed at present, but some of these solutions are designed to add hardware components to the circuit to compensate the brightness attenuation of the display unit. However, in order to pursue high-quality display effects, the pixel density is getting higher and higher. The complicated circuit arrangement in the space has extremely high requirements on the manufacturing process, and the yield rate is difficult to guarantee

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0025] see figure 1 , The embodiment of the first solution of the present invention provides a method for protecting an OLED screen. The OLED screen protection method includes the following steps.

[0026] S101. Sampling a screen signal of an OLED screen.

[0027] It should be noted that the screen signal includes a plurality of data signals and clock signals. In this embodiment, the screen signal may be the one data signal or clock signal.

[0028] S102. Detect changes in the sampled screen signal, and output a control signal when it is determined that the sampled screen signal remains unchanged or periodically changes for a first preset time period longer than a second preset time. Wherein, the first preset time is longer than the second preset time.

[0029] It should ...

Abstract

A protection method for an OLED screen is used to protect a screen in an OLED display. The protection method for the OLED screen comprises the steps that screen signals of the OLED screen are sampled(S101); a control signal is output when changes of the sampled screen signals are detected and the duration of invariableness or periodical changing of the sampled screen signals within first preset time exceeds second preset time, wherein the first preset time exceeds the second preset time (S102); and the OLED screen is controlled to be restarted according to the control signal (S103). In this way, long-term invariableness or periodical changing of images of the OLED screen can be avoided; the problem about ghost shadows on the OLED screen can be solved; and no hardware components and hardware circuits are added, so the cost is reduced.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to an OLED screen protection method and protection system. Background technique [0002] The current OLEDs (Organic Light-Emitting Diode, Organic Light-Emitting Diode) all have the problem of brightness attenuation. Moreover, due to the display content, the brightness attenuation is large in the place where the light is always on, often leaving afterimages, commonly known as "burn-in", which has become a defect of OLED displays. In order to solve the problem of OLED brightness attenuation, many solutions have been proposed at present, but some of these solutions are designed to add hardware components to the circuit to compensate the brightness attenuation of the display unit. However, in order to pursue high-quality display effects, the pixel density is getting higher and higher. The complicated circuit layout in the space has extremely high requirements on the manufacturin...
