Problems solved by technology

[0006] The present invention provides a display driving method and system for alleviating display afterimages, so as to solve the problem that the prior art can only distinguish between dynamic pictures and static pictures, but for the display scene where the same group of content is played repeatedly, it will be judged as a dynamic picture, but In the case of circular display, the boundary of the display content will appear repeatedly, which will still cause serious afterimages

Embodiment Construction

[0035] Please refer to figure 1 The display driving method for alleviating display afterimages in the present invention is executed by a computer host, and the computer host includes a motherboard and a processor electrically connected and arranged on the motherboard, a memory, a storage device, and an electrical connection Ports and other components.

[0036]The display driving method for mitigating display image sticking in the present invention includes: acquiring image boundary information S01, partitioning and collecting the boundary feature information S02, storing the boundary feature information S03, comparing boundary feature information and determining S04, and compensating for image sticking problems S05, and update S06.

[0037] The acquisition of image boundary information S01 is to perform boundary detection on the input display data (ie display screen content) to obtain boundary information, wherein the display data includes multiple frames of different picture...

Abstract

The invention discloses a display driving method for alleviating display afterimages. It performs boundary acquisition and feature sampling on input display data, and regularly stores and updates multiple groups of boundary feature information, and combines the detection results of display data boundary information with the stored data. For comparison, when multiple groups of boundary feature information appear repeatedly, it is judged as a circular picture, and only a single set of boundary feature information repeatedly appears, then it is judged as a still picture. A looping picture or a still picture is judged as a dynamic picture, and the compensation algorithm is not activated. Through this driving method, the purpose of optimizing the compensation effect of the afterimage problem and prolonging the life of the display is achieved.

Description

technical field [0001] The present invention relates to a display driving method, in particular to a display driving method and a system thereof for alleviating display afterimages. Background technique [0002] Existing liquid crystal (Liquid Crystal Display, LCD) displays, active matrix organic light emitting diode (Active Matrix Organic light Emitting Diode, AMOLED) displays, etc., in the daily application process, the afterimage problem has a great impact on the display quality, becoming The key factor restricting the service life of the display. In order to reduce the influence of the afterimage problem on the display effect of the display and prolong the service life of the display, a variety of display afterimage compensation algorithms have been developed in the industry. [0003] Existing solutions to the afterimage problem are mainly based on picture characteristic judgment and boundary detection. The common methods are as follows: First, based on the detection an...
