Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages in the above-mentioned background technology, and provide a method for protecting the screen of an OLED TV based on pixel movement, which uses the method of pixel movement to prevent a single position displayed on the screen from displaying high-brightness pixels all the time, thereby avoiding partial residual screen. To achieve the purpose of protecting the screen, to solve the technical problem that the screen cannot be protected from afterimages when the OLED TV is in the operating state or playing state

Embodiment

[0019] A method for protecting OLED TV screens based on pixel movement, comprising the following steps:

[0020] A. Receive raw image data;

[0021] B. Create a pixel movement thread;

[0022] C. When the OLED TV is in the state of being operated or playing, in the thread, all the pixels on the screen are moved circularly with their own position as the coordinate origin according to a certain trajectory.

[0023] Specifically, in this embodiment, when the pixel point moves in step C, it moves circularly according to a rectangular trajectory, and the pixel point moves once every 15s. Considering the size and invisibility of the screen, in this embodiment, the horizontal movement unit is set to is 7 pixels, and the vertical movement unit is set to 4 pixels, so as to achieve an optimal movement trajectory.

[0024] Such as figure 1 As shown, it is the specific moving track of a pixel point P in this embodiment:

[0025] The original position of the pixel point P is P 0 (0, 0...

Abstract

The invention discloses an OLED television screen protection method based on pixel movement, comprising the following steps: receiving original image data, creating a pixel movement thread; when the OLED television is in an operated state or a playing state, making all pixel points on the screen in the thread move according to a certain trajectory. The OLED television screen protection method based on pixel movement of the invention The pixel movement method prevents the single position of the screen display from displaying the high-brightness pixel point all the time, thereby avoiding the residual image of the screen locally and achieving the purpose of protecting the screen. The invention can solve the technical problem that the screen cannot be protected from residual image when the OLED TV is in the operated state or the playing state.

Description

technical field [0001] The invention relates to the technical field of TV screen protection, in particular to an OLED TV screen protection method based on pixel movement. Background technique [0002] With the development of technology, TV products equipped with OLED screens are gradually increasing, but OLED screen modules are prone to image afterimages in the display principle. Once image afterimages occur, the entire screen cannot meet the needs of use. It is very expensive, so some processing needs to be done on the display of OLED TVs, so as to increase the service life of OLED screens. [0003] At present, various TV manufacturers only reduce the brightness to avoid afterimages, that is, when the user does not use the TV for a period of time, the screen saver is automatically activated and the brightness is reduced. However, this method is only when the TV is turned on and not in use. Only in order to protect the screen, when the TV is in the state of being operated o...
