A remote radio head unit (RRU) system for multiple operating frequency bands, multi-channels, driven by a single or more wide band power amplifiers. More specifically, the present invention enables multiple-bands RRU to use fewer power amplifiers in order to reduce size and cost of the multi-band RRU. The present invention is based on the method of using duplexers and / or interference cancellation system technique to increase the isolation between the transmitter signal and receiver signal of the RRU.

The present application provides a ligand-modified quantum dot material, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel. The ligand-modified quantum dot material of the present application can occur a polymerization with the ligand-modified quantum dot material under ultraviolet irradiation to form a polymer, while the polymer deposits on a substrate to form a polymer film, which can replace the PI alignment film, so that an alignment process of liquid crystal is simplified, and a cost is economized; simultaneously, display quality of a liquid crystal display panel can be improved by the quantum dots anchored in the polymer film. The method of fabricating the liquid crystal display panel of the present application eliminates the fabricating process of the PI alignment film, the method has simple process and low cost, and a liquid crystal display panel obtained thereby has better display quality. The liquid crystal display panel of the present application utilizes the polymer film, which is obtained by polymerizing the ligand-modified quantum dot material and a polymerizable monomer, to replace the PI alignment film, so as to greatly enhance quality of the panel, and to have a low fabricating cost.

The present invention relates to an optically integrated device, and more particularly, to an optically integrated device with low light loss. The optically integrated device includes an optical condenser to condense the light before the light enters an optical integrator. A color filter is attached on the optical integrator to filter through a portion of the light, and reflect the other portion of the light into the optical integrator. The optically integrated device recycles the reflected light inside the optical integrator to prevent the light loss.

A manufacturing process of an embedded type flexible or rigid printed circuit board includes multiple steps. First, a layer of dry film is applied to a layer of copper foil. Then a circuit pattern is formed on the copper foil through photolithography processes. An etching stop layer is electroplated on the copper foil according to the circuit pattern. The etching stop layer is then electroplated with copper. The copper foil is softened by a high temperature process after removing the dry film. Then the layer of the copper foil is etched after coating with an organic layer and the organic layer is solidified.
