Active Shutter Progressive 3D Method The display alternately shows images for the left and right eyes. The left and right lenses of the eyewear open and close in sync with this display timing to show separate images to the left and right eyes. By repeating this action at high speed, the brain perceives 3D images. And because this method displays FULL HD 3D images just as they are, both eyes receive 3D images in high, full-HD quality. 2,500 Focused Field Drive This original Panasonic technology detects image movements like the human eye, and optimizes the drive accordingly. By achieving instantaneously powerful light emission rather than finely divided emission, it reduces the afterimages that cause blurring. As a result, fast movement is reproduced with excellent clarity.
