We have utilized a transmission ratio (TR) between curtain-shaped (Curtain) Mura and non-Mura zones as a key parameter to characterize the optical appearance of Curtain Mura occurred on a 13.3-in TFT–TN panel (Mura sample) after bonding process to place silicon-based driver-IC chips on one of the panel substrates using anisotropic conductive film as a binder (COG ACF process). Our measured TRs ...

The paper aims at building a history-friendly model which replicates the history of the Thin Film Transistor-Liquid Crystal Display (TFT-LCD) industry focusing the crystal cycle and co-evolution of demand, technology and industrial structure. The most interesting characteristic of the TFT-LCD industry is the cyclical behavior of the price and investments. The model is distinctive compared to ex...

Purpose – This paper seeks to construct a model for inventory management for multiple periods. The model considers not only the usual parameters, but also price quantity discount, storage and batch size constraints. Design/methodology/approach – Mixed 0-1 integer programming is applied to solve the multi-period inventory problem and to determine an appropriate inventory level for each period. T...

Due to the progress of high technology, TFT-LCD (Thin Film Transistor – Liquid Crystal Display) has been widely put in use recently. The manufacturing technology of the TFT-LCD industry mainly consists of array, cell, module processes, in which there exists special characteristics such as different objectives of individual process’s scheduling, complexity of manufacturing processes, and multi-s...

A solution-processed photosensitive passivation layer with a low dielectric constant (PPLD) has been developed for an a-Si thin film transistor. The PPLD has three highly important properties: a low leakage current, low water absorption, and high-transparency. In addition to providing passivation, the PPLD doubles as a planarization layer. The photoactive property of the PPLD is convenient for ...

Amorphous silicon (a-Si) thin film transistors (TFT’s) were fabricated on free-standing, clear plastic substrates with a maximum process temperature of up to 250°C. An a-Si TFT backplane for active matrix OLED (AMOLED) application was also made on such substrates. The performance of both the TFT’s and the AMOLED backplane are excellent. These results will enable the fabrication of flexible AMLC...

This study describes the performance evaluation of an energy management system, based on electricity consumption, for a Gen 6 Thin Film Transistor Liquid Crystal Display (TFT-LCD) panel plant. Of the various production lines and facility systems, the array system and the compressed dry air consumed the most electricity of 21.8% and 19.8%, respectively, while the public utility used only 1.6% of...

Article history: Received 27 September 2007 Received in revised form 4 October 2008 Accepted 15 June 2009 With the rapid advancement of technology, product life cycle is shortening continuously. In order to compete against other firms in fiercely competitive global markets, a firm has to keep developing new technology to differentiate itself from others. The acquisition of new coretechnology eq...

In this paper, we present an effective defect inspection system that identifies film defects and determines their types in order to produce polarized films for TFT-LCD (thin film transistor – liquid crystal display). The proposed system is designed and implemented to find defects from polarized film images using image segmentation techniques and to determine defect types through the image analy...

For thin film transistor-liquid crystal displays (TFT-LCD) factories in Taiwan, yield performance had become as an important competitiveness determinant during the competitive environment. As we known, the market for LCDs has grown at over 20% on average per annum and the downward pricing trend had also promoted LCD applications. However, only few studies were proposed to address the related is...
