Dynamic focus voltage error of projection display system was studied in this article. Parabola dynamic focus method, projectiontube shape and optics processing were analyzed.
Results Optimal tube voltage and milliampere parameters of the full-length leg projection was acquired in terms of the distribution of spatial resolution under different parameters of exposure.
