| Abstract(in English) | An ultrahigh-definition display system quadrupling the horizontal and vertical resolution of HDTV has been developed. This system consists of two LCD projectors, one is for green and the other is for red and blue. So convergence errors between green images and red/blue images occur on the screen. We introduce the automatic convergence adjustment method which obtains convergence errors by displaying mountain-like patterns and using a digital-camera. The projector for green images has the resolution of equivalent 7680 × 4096 pixels with spatial pixel offset method using two 3840 × 2048 LCD panels. So two green panels must be located with an exact spatial offset of 0.5 pixels. We realize a method which can detect a misalignment of spatial offset by using two sine-wave patterns with different phases each other. |
