Abstract: A maskless exposure system that has multiple maskless optical engines arranged in an (N×M) matrix that form and project a pattern onto a substrate. A first stage system is capable of driving the maskless optical engines in a first direction, a second stage system capable of holding and moving the substrate in a second direction perpendicular to the first direction. A control system that processes data and synchronizing movement of the first and second stage systems and a vision system that detects the positions of the second stage system to synchronize movements with the multiple optical engines.

Abstract: A double-sided maskless exposure system and method consists of light sources which includes two light wavelength segments, maskless optical engines in which a 2D spatial light modulation (spatial light modulator) device, such as DMD, is generating a plurality of pixel array of the pattern, vision system, moving substrate and computer control system. The double-sided maskless exposure system at least includes two maskless optical engines with auto-calibration function which can correct any alignment error in-line. Each optical engine is for each side of the substrate. The optical engines are aligned each other in pairs and are simultaneously patterning on each side of the moving substrate. The system also includes a manipulator for moving, stepping or scanning the optical engines, relative to the substrate so that it can create a contiguous whole image on the both sides of the subject.

Abstract: A high efficiency micro projection optical engine includes a light source module, a lens assembly, a micro display panel and a projection lens. An image of the luminous surface of light emitting elements of the light source module is formed in the vicinity of the micro display panel. The micro display panel is arranged on the path of emission light of the lens assembly to modulate incident light and obtain image light with image information. The projection lens is used to project the image information on the micro display panel and form an image onto a screen. The optical engine enhances efficiency by means of critical illumination.
