Title: Method to elongate the lifetime of plasma display panel by dynamically adjusting the intensity of input image signal
Inventor: GAU SHIU-BIN
IPC: G09G3/28
Filed: 2001-04-03
Granted: 2003-01-01
Abstract: The present invention is a method to elongate the lifetime of plasma display panel (PDP) by dynamically adjusting the intensity of input image signal, wherein the fluorescent body of the three primaries coated on each discharge cell of the PDP is proceeded with experiment to analyze the reduced light-emitting efficiency of the cell gray scale of each fluorescent body due to the increase of usage time. Also, a time function is utilized to estimate the correspondence relationship between the red, green, or blue color gain generated corresponding to the cell gray scale of each fluorescent body and to the usage time, and set up a comparison table of the experience value based on it, so that the control circuit of PDP can select each corresponding gain from the comparison table according to the usage time to dynamically adjust the intensity of input image signal of each discharge cell, and the generated red, green, blue color can exactly compensate for the reduced light-emitting efficiency due to the increase of usage time of the fluorescent body, so as to effectively eliminate the negative effect to the lifetime of PDP resulted from the color temperature and color deviation, thereby making the picture display the image with the best color and greatly elongating the lifetime of the conventional PDP.
