Abstract: A color filter manufacturing method for a plastic substrate uses an extrusion process to form a plastic substrate with multiple grooves. Then, it uses inkjet printing method to jet photo resists into the groove of the plastic substrate after defining the primary colors of red R., green G., and blue B. The method can overcome the problem happened in the conventional CF photolithography process. This, therefore, can simplify the manufacturing process, and can apply to the large-area plastic substrate of a color filter.

Abstract: An optical detector measuring a movement of an object in a space on a measurement axis comprises a light source, a reflective portion, a detection unit and a converting unit. The light source comprises a resonance chamber, the light source emitting a laser beam toward the object, the laser beam contacting the object and generating a first scattering beam and a reflection beam, wherein a part of the first scattering beam enters the resonance chamber. The reflective portion reflects the reflection beam toward the object, the reflection beam re-contacting the object and generating a second scattering beam and a sub-reflection beam, wherein a part of the second scattering beam and the sub-reflection beam enter the resonance chamber. The detection unit measures an optical-electrical variation in the resonance chamber to generate an electric signal. The converting unit converts the electric signal to a movement on the measurement axis in the space.
