Knowledge flows and innovation capability: The patenting trajectory of Taiwan's thin film transistor-liquid crystal display industry

Abstract

This paper uses USPTO's patent data to present and analyse knowledge flows and innovation capability within and across Taiwan's top five major players in the thin film transistor-liquid crystal display (TFT-LCD) industry. Based on the empirical results, the study shows that latecomers, such as Taiwan, to the TFT-LCD industry have internalised external knowledge from the US and particularly from Japan on specific core technologies, while the knowledge relationship between source and recipient is un-intimated. One important finding of this study is that Taiwan's top five TFT-LCD manufacturers possess different knowledge sources and technology focuses. This specialised capability is most likely the cause for their positions in the market (i.e. market share). Each player has unique patenting protocol, in which the coded knowledge (i.e. patenting rate) does not act as a major indicator of innovation performance in Taiwan's TFT-LCD industry. Remarkably, the public research institute does not show its essential impact on TFT-LCD industry as it once was in most East Asian latecomer literature. This study thus provides some useful managerial implications for latecomer firms to facilitate knowledge internalisation and build endogenous innovative capabilities.
