Abstract
Back Light Unit is the one of TFT-LCD Panel’s key modules. The ability of technology to conduct process innovation is one of the most important competition for manufacturers. In the Back Light Unit industry, the quality of production and output will rise continuously due to customers’ demand and Back Light Unit company must continue to provide production process innovation and improvement. This study is to study technological development and the main production process innovation of the Back Light Unit company. One of the main findings is that firm need to match the process innovation capability with the product innovation in order to adopt new product structure and material design to achieve the desire reduction of cost. Then, more competitive production manufacturing can become a standard procedure for the other manufacturing factories or industries.
