Patent ID: 10809603

Abstract:
The invention discloses a novel LCD projector, comprising an imaging system with single-light path system for LCD projector time-division display, a lighting system with PCS (P light converted into S light) function, a three-primary-colors LED light source with microlenses, and a heat dissipation system with dust-proof and self-cleaning function; the monochrome LCD screen of the imaging system has a high light transmittance and resolution, achieving higher brightness and resolution; the lighting part has a polarized light conversion function, which converts the useless P light into useful S light, improving the light utilization and increasing the brightness; a transparent antifouling coating is applied on the optical components of the heat dissipation system to reduce dust adsorption; ultrasonic vibrators are mounted on the optical components to shake off the dust attached; the light source uses the microlens to converge the three-primary-color LED light source to improve light efficiency and uniformity.
