Noise-immunity enhancement technologies for on-cell touch-panel LCDs

NLT Technologies, Ltd. Hiroshi Haga

NLT Technologies, Ltd.

Senior Research Engineer, Research & Development Department

Hiroshi Haga

Technologies for noise-immunity enhancement for capacitive touch screens are described in this session. We focus on following technologies; a technology for avoiding the noise originated from LCD driving, a parasitic current reduction technique which removes the current flowing through the parasitic capacitance on a capacitive sensor, and a correlated noise subtraction method, which improves the signal-to-noise ratio even under an environment where noise frequency coincides with signal frequency. These technologies have been demonstrated with our on-cell touch-panel LCD based on surface capacitive technology.

Hiroshi Haga received his B.E. degree in image science and technology from Chiba University, Japan, in 1994. He then joined NEC Corporation, where he was engaged in the research and development of polycrystalline silicon TFT circuits and their application devices such as image sensors, LCDs, EL displays. In 2011 he transferred to NLT Technologies, Ltd. and has been working on HCI technologies. Hr.

Product & Service Dept. · Corporate Manager

Ryoji Ihara

The sharp growth in the number of smartphone users in the market has led to increased demand for new user interfaces in products and services to match trends such as "mobile first" and surging consumerization. This session discusses the development of the Natural User Interface (NUI), offering high usability. Applications for Windows 8 are designed around the basic concept of "touch first." When conventional form applications are redesigned for touch operation, it is important to not only allow fingertip-controlled sizing, but also evaluate the design for particular usage scenarios based on clearly defined touch significance and objectives. The session examines the conceptual approach to the development of such touch applications, the concrete investigation process, and design considerations.

After working in content distribution service operation, BREW application development, and the development of embedded system GUIs for public/medical/manufacturing system applications at a manufacturer, the speaker entered Second Factory in 2005. He has since utilized his experience in GUI development in product planning and design of touch devices and cloud-based products.

C-31 Touch Panel/ITO Substitute Film

Touch panel and sensor electrode film: A core technology for thin, light devices - The key to capacitive design quality -

Nov 2(Fri.) 10:00 - 12:30
Conference Center 3F

ITO film is the most commonly used type of transparent electrode film, indispensible in touch panels. ITO material, however, is difficult to layer on heat-sensitive resin substrates, and transparent electrode characteristics degrade compared to ITO film on glass substrate. As a result, development of a replacement for ITO film is active. Possible alternatives, however, will have to overcome a number of obstacles before they can achieve widespread adoption. The session examines the latest trends in sensor electrode film technology, and the outlook for the future.

Enabling Large Area and Flexible Touch-Enabled Displays

Cambrios Technologies Jonathan Westwater

Cambrios Technologies

Applications Engineering Manager

Jonathan Westwater

Already accustomed to the touch experience, consumers now expect an advanced, intuitive and rewarding touch experience. As a result, the touch-enabled display market is growing and advancing rapidly, particularly in the Ultrabook and all-in-one categories. Consumers are demanding larger, better performing displays with innovative designs, flexible screens and curved surfaces. With the impending launch of Windows 8, high-performance touch capabilities are quickly becoming a necessity for many devices. At the same time, OLED technology is advancing, and has become a significant alternative to LCDs with more than 100 million sold in the last 12 months. Samsung and other major CE manufacturers are even touting a new wave of curved and flexible OLED displays.
This is an exciting time for the display industry, but these new innovations require transparent conductor materials that combine low material and processing costs with flexibility, high conductivity, and excellent optical performance. Previous generation ceramic conductive materials like Indium Tin Oxide (ITO) are unable to offer these qualities and are a major inhibitor to the development of these markets.
Fortunately, a new generation of transparent conductive materials has arrived to enable the flat panel display market. Unlike brittle ITO, new transparent conductive materials are ductile and offer the flexibility required in curved displays. These new materials, including one made from silver nanowires, are ushering in a new era of flexible, touch-enabled displays that will be available very soon.

Jonathan Westwater is the applications engineering manager at Cambrios Technologies. Prior to joining Cambrios, Jonathan served as the project liaison manager for Japan and the United Kingdom at Sony. Previously, Jonathan held positions as a technical support manager at Sumitomo Sitix Silicon and research engineer at Sony.

Westwater holds a bachelor's degree in Physics from The University of Sheffield, a master’s degree in Amorphous Electronic Materials from University of Dundee, and a doctorate in Electrical Engineering from Gifu University in Japan.

Kazuhiro Oshima

It is said that "One Glass Solution" abbreviated as "OGS", which is known as the major production system for next-generation touch screen panel, is predominant compared with IN-CELL system and ON-CELL system from the viewpoint of "easy-to-manufacture", cost performance and so on, and also said OGS will be widely adopted. However, there are some problems of OGS; because of processing tempered glasses, mainly loss of glass strength due to edge-surface processing and lower yield by scratches on the top surface during processing. On the other hand, lamination processing system of tempered glass with temporally fixing adhesive "TEMPLOC" developed by DENKI KAGAKU KOGYO K. K. has processed already about 10 million pieces as solving the above problems. In this occasion, I'd like to introduce not only technical advantages of our "TEMPLOC processing" in particular but solution against lower yield by increase in decorative area (BM area) and narrower surrounding area and a problem of lack of strength in the hole area. Also, I’d like to unveil a new processing system and material to increase strength and yield more after processing.

Up to now, mask exposure machine has been used in order to expose photo resist for circuit patterning in print circuit board process. Now, direct imaging is getting popular for reasons of cost reduction and manufacturing of high difficulty product. Direct imaging has function that measures the position and scaling of work panel, modifies the pattern data based on measuring result before exposing and exposes the modified data. Orbotech has released direct imaging machine for touch panel process and start to use direct imaging machine in OGS process. The application example will be introduced in this presentation.
