Display Photonics promises efficient, bright, small and cheap pico projectors

Display Photonics Systems (DPS) is a new start-up that has developed a new single-panel projection technology called Angular Color Projection (ACP). They claim that their solution is more efficient, brighter, smaller and cheaper than current solutions. DPS has already been granted some patents and created a fully working prototype. They are now seeking funding to complete product development and create a pilot production line in China.

Here's how they describe the technology: RGB images are displayed side by side simultaneously on a single microdisplay panel and proprietary projection lens converges the RGB images to a full color image. At a certain plane within the projection lens, RGB color lights are distributed (encoded) at different angles. A set of dichroic mirrors are then used to converge RGB lights.

ACP can be used with an HID lamp, White LED, RGB LED or laser. The technology allows for future migration to OLED based (self emitting) projectors.
