Chiara Cometti

Electrowetting display technology provides a high image quality that can be operated in all display modes: reflective, transflective and transmissive [1]. Furthermore, content dependent refresh rates can be achieved down to 1 Hz, leading to low power consumption that preserves the battery life of portable electronics [2]. A further power reduction can be achieved by reducing the driving voltage. This can be realized without reducing the optical performance by optimizing various pixel parameters, such as pixel dimensions and layout, properties of the light absorbing liquid phase, dielectric thickness reduction and dedicated driving schemes. Improving these characteristics requires in-depth knowledge about the electrowetting material properties. Experimental data along with modeling results will be presented to resolve the most important parameters to enable highly energy efficient electrowetting displays.

Chiara Cometti is Samsung LCD Netherlands R&D Center’s Senior Development Engineer responsible for development of new key processes and materials for innovation for electrowetting displays. She holds a Master’s Degree in Materials Engineering from the distinguished Polytechnic of Milan. Prior to working for Samsung, Ms. Cometti fulfilled key engineering positions at various high tech companies. She is co-author of numerous publications and is the owner of multiple patents, granted and pending.

Mobile technology has the power to revolutionize education. There is an opportunity to put a library in every backpack. This library carries thousands of books, is open 24x7x365 and can be accessed anywhere in the world for less than $100 - without any late fees. Today, we are in a knowledge economy, yet that knowledge is transmitted via a 500-year-old medium called the printed book. Books are very readable, but their content can't be changed. Electronic displays on computers and tablets are changeable, but they are difficult to read at length and multi-functional to the point of being distracting. This presentation will examine the merits of a mobile library that could revolutionize education.

Sang-Hee Ko Park

The most noticeable display trend is to achieve high resolution in mobile and large size panel. The common technology issues in terms of backplane of high resolution display are 1) TFT with high mobility and high stability, 2) the way to reduce the cost of fabrication, 3) low resistive electrode for large size display, which is related to the process on the large size substrate using simple process at high yield, and 4) TFT with less parasitic capacitance.
We have intensively developed oxide TFT technology during last 8 years in terms of active material, process, device structure and device physics. Finally Sharp started mass production of LCD panel and LGD is making AMOLED with oxide TFT. There are, however, several problems which are not solved yet. Here I will explain the recent issues of oxide TFT and development status. Finally, I will present the efforts to improve the performance of oxide TFT which would make oxide TFT be suitable for the backplane of next generation of display.

Kikuo Ono

IPS-LCDs have been widely used for TV application since they have an advantage of wide viewing angle performance. In addition, recently they have come to be used rapidly for smart phones and tablets. The reduction of power consumption is extremely important for those mobile applications in order to lead to low power consumption, namely, the realization of long-term use of battery time.
The panel power consumption as well as the back light consumption deeply related to the aperture ratio should be much reduced. The TFT pixel driving method must be changed from a dot inversion to a column line inversion one.
An innovative IPS pixel structure has been developed to reduce both consumptions. This pixel structure has a function of the transparent common electrode which can shield by covering TFT wirings via insulating films over plurality of pixels. We have named IPS-Pro-Next as a pixel structure.
In this presentation, we will introduce the principle how to improve the aperture ratio using IPS-Pro-Next. Furthermore, newly developed IPS photo-alignment technology will be introduced. This pixel structure including the photo-alignment is a superior technology of Panasonic Liquid Crystal Display Co., Ltd. for realizing high ppi LCDs based on our intellectual property

Professor

Chihaya Adachi

We demonstrate nearly zero-gap formation (δEST) between singlet and triplet excited states by separating highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) which can be provided by proper combination of an electron-donar and an electron acceptor. The application to an emitter layer in organic light emitting diodes (OLEDs) resulted in very high external electroluminescence (EL) efficiency , indicating that triplet excitons generated by carrier recombination efficiently up-convert into a singlet state, resulted in a radiative decay as delayed EL.
