ASLM Multi-Display Tech ID: UA19-113 Invention: This technology is a new method that illuminates digital micromirror device (DMD) with focusing, homogenous illumination with cone angle/numerical aperture/F-number configured to prevent contaminated light to enter incorrect pupils. The technology has one input pupil and multiple diffraction order pupils that produce a multi-display from just one projector. Background: Digital micromirror device (DMD) is an array of micromirror pixels that traditionally are an alternative between ON and OFF positions that direct towards or away from a projection lens for an image projection. Traditional DMD will run into issues where there is light contamination or where the chief ray-of-incidence design is not parallel. These issues can lead to significant diffraction ringing in transmission of light and can prevent high-quality projection. This technology focuses on a new illumination method that mitigates the chance of light contamination to enter and works towards providing a higher quality of projection. The projection can replace the need of having multiple projectors. The technology can cover multiple projections on a screen which allow it to be used for various applications.
