Abstract

Projection TV cabinets are bulky. Increasing the projection angle from ±25° to ±400° significantly reduces the size of the cabinet, but introduces severe requirements on the lens design to correct the large aberrations and poor illumination at the corners of the picture. Simpler designs with improved performance are possible if the cathode ray tube faceplate is curved.
