METHOD AND DEVICE FOR NOISE REDUCTION IN A PULSE-WIDTH CONTROLLED IMAGE DISPLAY DEVICE

摘要

The present invention relates to the pulse width controlled image display devices of a kind of method and noise. It monitors whether that the brightness of multiple successive image points is bright to occur in given luminance threshold value. If it is not the case, but in addition to this input signal of constant delay is supplied to display. On the other hand,If the brightness of multiple successive image points is less than the brightness value of given threshold value, the average value which generates multiple successive image points occurs and wherein described is supplied to display.
