58.4: Invited Paper: Flexible Displays and Electronics Made in AM-LCD Facilities by the EPLaR™ Process

Flexible displays have significant advantages for handheld devices by being thin, light, robust and capable of being fitted to curved shapes. We have developed the EPLaR process for making flexible displays in standard AM-LCD factories. In this paper we discuss EPLaR electrophoretic displays driven by a-Si TFTs that were made in a factory and report on progress in developing flexible polycrystalline silicon TFTs and OLEDs.

22.3: A 3.4-inch Reflective Colour Active Matrix Liquid Crystal Display without Polarisers

A 3.4″ reflective colour AMLCD was developed using the standard a-Si:H TFT technology and a vertically aligned dyed cholesteric liquid crystal mixture. Optimised liquid crystal mixture, de-saturated colour filters and high pixel aperture ratio were achieved in order to demonstrate a high reflectivity with an acceptable contrast ratio in a large viewing cone.

7.2: A 4.3-inch Full-colour a-Si:H TFT Active Matrix Liquid Crystal Display with 312 ppi

A 4.3″ full-colour AMLCD with a density of 312 pixels per inch was developed using a standard a-Si:H TFT technology. This display is compatible with high definition professional monitors and more precisely for collimated head display applications in term of transmission, reflectivity, viewing angle, colour purity and automotive environmental conditions.
