Abstract

Self-developed three- primary color laser projection TV based on RGB (RED, GREEN, BLUE） laser diode is given by this paper. Laser diode has very narrow line-width, high color purity and saturation, and displays more colorful and gorgeous image. In this work, the Helmholtz-Kohlrausch effect is applied for studying the enhanced perceived brightness of the RGB laser projection television. The experiments are designed for the difference perceived brightness between the RGB laser projector TV and the Blue laser- excited phosphor laser projection TV. The ratio of the enhanced perceived brightness of RGB laser projector TV is evaluated.
