Projection device and a method of manufacturing a projection device

摘要

The present disclosure provides a projection device and manufacturing method, comprising the steps of fixing the positions of a red light source, green light source and blue light source so that the light sources are immovable; providing a mirror which is configured to oscillate such that it can scan light it receives across a display screen; positioning an optical component, which is configured to deflect light, such that it can receive red, green and blue light beams outputted from the red, green and blue light sources respectively; adjusting the optical component such that the optical component compensates for variation between the light sources, in the direction in which the red, green and blue light beams are output from the red, green and blue light sources, so that each of the red, green and blue light beams are directed to the same point on the display screen.

主权项

1. A method to manufacture a projection device, comprising:
fixing the positions of a red light source, a green light source and a blue light source, the red light source, the green light source and the blue light source to emit red, green and blue light beams, respectively; providing a mirror, the mirror to reflect the red, green and blue light beams and to oscillate to scan the red, green and blue light beam across a display screen; positioning an optical component to deflect the red, green and blue light beams to the mirror; and adjusting the optical component to compensate for variation between the direction in which the red, green and blue light beams are output from the red light source, the green light source and the blue light source to direct each of the red, green and blue light beams to the same point on the mirror, wherein the mirror to scan the red, green and blue light beams to the same point on the display screen.
