Abstract
A projection apparatus is provided. The projection apparatus includes a light-emitting unit array, an optical sensor, and a control unit. The light-emitting unit array is for emitting an image beam. The optical sensor is for detecting electromagnetic waves so as to generate a signal. The control unit is electrically coupled to the light-emitting unit array and the optical sensor for controlling emission of the light-emitting unit array according to the signal from the optical sensor.
Claims33
An projection apparatus adapted to project an image beam so as to form an image, the projection apparatus comprising:
- a light-emitting unit array for emitting the image beam, the light-emitting unit array comprising a plurality of light-emitting units monolithically integrated;
