Abstract
A system comprising of low cost and low power projection engine comprising of means of producing non-coherent light source, means of condensing non-coherent light into narrow beams, means of focusing and scanning narrow beam light on screen where as image is projected on screen by producing light for each pixel of image. Source of non-coherent light can be LED.

A system comprising of projection engine which further comprising of
- means of producing non-coherent light for each pixel
- means of focusing and scanning light on screen
- where as image is projected on screen by producing light for each pixel of image in sequence, by focusing light for each pixel on screen and by scanning produced light across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.
A system comprising of projection engine which further comprising of
- means of producing non-coherent light
- means of condensing non-coherent light into narrow beams
- means of focusing and scanning narrow beam light on screen
- where as image is projected on screen by producing light for each pixel of image in sequence, by condensing said light into narrow beam, by focusing light for each pixel on screen and by scanning said narrow light beam across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.

A system comprising of projection engine which further comprising of
- means of producing non-coherent light of plurality of color beams
- means of combining plurality of color beams into fewer beams
- means of focusing and scanning combined light beams on screen
- where as color image is projected on screen by producing light beams of plurality of colors for each pixel of image in sequence, by combining said plurality of color beams into fewer beams, by focusing said combined light beams for each pixel on screen and by scanning said combined light beams across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.
