Method of preventing image sticking on a tft-lcd

A method of preventing image sticking on a TFT-LCD;

• comprising the manners of
• connecting a TFT-LCD to the display control board so that signals are communicated therebetween;
• using the display control board including a micro-controller to determine whether a timing of input signals is changed, in which if the timing of input signals do not change within a setting time period, then the image pixels of the TFT-LCD is changed and thus the shapes of the liquid crystals of the TFT-LCD are changed;
• TFT-LCDTFT-LCD controlling the illumination and movement of the image pixels of the liquid crystals of the TFT-LCD for prevention of image sticking;
• movement of the image pixels inclusively causing an image frame to move upwards, downwards, leftwards, and rightwards, scanning lines, and moving by “scan point” scanning;
• and
• Providing an OSD setting device for settings of display image-sticking prevention in three modes:
• Mode 1 in which the manners of protection of scanning “surface”, “line”, and “point” that move in 4 directions are provided;
• Mode 2 in which the manners of protection of scanning “line” and “point” are provided;
• and
• Mode 3 in which the manner of protection of scanning “point” is provided;
• The program looping for displacement per 8 hours by default;
• when the input signal is not changed, the image-sticking prevention working in a mode selected on the OSD setting device.
