Example Embodiment

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0038] The present invention adopts different solutions for different scenes that produce image retention. It adopts a series of anti-image retention strategies, including screensaver display strategies, various module display protection requirements, measures to reduce the loss of the OLED screen, and the OLED screen itself to prevent image retention. Technology for processing. Since the pixel points are more likely to have afterimages when the brightness is high for a long time, the present invention appropriately reduces the brightness of the OLED screen, so that the light emit...

Abstract

The invention provides a television anti-ghost processing method, a television and a storage medium, and the method comprises the steps: detecting whether a display image on an OLED screen changes ina first preset time or not if an OLED screen of a television is in a lightened state; and if not, judging a display picture on the OLED screen as a static picture, and controlling the OLED screen to reduce the brightness according to a preset rule. According to the invention, the brightness of the OLED screen in a static picture is properly reduced; the pixel points on the OLED screen are not in ahigh-brightness state for a long time, the probability of ghost shadows is reduced, the fault rate of the ghost shadows of the OLED screen can be effectively reduced, and the service life of the OLEDscreen is prolonged while it is guaranteed that a user normally uses the OLED screen.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a processing method for preventing afterimages in a television, a television and a storage medium. Background technique [0002] OLED (Organic Light Emitting Display) display technology has the characteristic of self-illumination. It uses very thin organic material coating and glass substrate. When an electric current passes through, these organic materials will emit light. OLED responds quickly, has higher contrast, has a wider viewing angle, and saves power. At present, OLED displays have been widely used in display devices such as televisions, mobile phones, and digital cameras. However, the OLED display also has its own defects. Because each pixel is free to emit light, when it stays on a still picture or an incomplete still picture for a long time, it will produce afterimages, commonly known as screen burn-in. This kind of afterimage phenomenon is more serious. , it wi...
