Abstract: An equipment for testing a plurality of projector modules is provided, wherein the equipment includes a screen, a mask, at least one camera and a controller. The mask is positioned between the screen and the projector modules when the projector modules are within the equipment, and the mask is arranged to mask a plurality of projected images generated by the projector modules so that only a portion of projected images is allowed to be projected to the screen. The camera is arranged for capturing the portion of projected images on the screen. The controller is coupled to the camera, and is arranged for analyzing the captured images to control settings of the projector modules.

Abstract: A projector assembling equipment includes a holder and at least one multi-axial adjusting device. The lens module or the light source module is disposed on the holder. The multi-axial adjusting device is connected with the holder to move the holder relative to a reference plane, and the reference plane is used to put the lens module or the light source module which is not held by the holder. The multi-axial adjusting device includes a three-axis adjusting mechanism, a rotary adjusting mechanism and a tilt adjusting mechanism. The three-axis adjusting mechanism is utilized to shift the holder at a first direction, a second direction and a third direction. The rotary adjusting mechanism is disposed on the three-axis adjusting mechanism to rotate the holder at a clockwise direction and a counterclockwise direction. The tilt adjusting mechanism is disposed on the three-axis adjusting mechanism to recline the holder relative to the reference plane.
