A Virtual Pixel Software and Hardware Technology to Increase Projector Resolution

摘要

Increasing the resolution of the LCD (or similar) display used in projectors (in conjunction with increased light emissions, etc.) increases the resolution of the projected image and/or the distance that the projector can be from its screen. While increasing the size of the LCD panel represents one approach to producing increased resolution, this increases projector size and weight. This paper proposes the introduction of a mechanism to allow multiple pixels to be combined to create a higher resolution output image than the LCD (or similar) display used to create virtual pixels, increasing the effective resolution of the projector.
