Controlled gain projection screen
摘要:
Light scatter control is provided in rear projection and front projection of light images focused upon a screen having a liquid crystal droplet film, and modulated light gain control of single and multi panel screens is provided, without size restriction, maximizing light transmission and reflection, for brilliant high resolution viewing of cinema and video regardless of high degree of ambient light. Panels of liquid crystal film lamina and associated laminates are joined by imperceptible optical splicing.
