Technology overview: Resistive touch screens are being fast replaced by capacitance screens along with appearance of iPhone, etc. because capacitance screens provide a much softer touch. Today, a touch screen has become the most preferred input device as it allows a user to perform more easily and instinctively.
A slim touch sensor technology, which is applied to a wide range of devices such as tablet PCs in addition to smartphones, appears to be emerging as a major trend in the area. A touch sensor with integrated window does not require ITO film and thus can be made slim with competitive prices, high transmittance, and thin bezel. Integrated windows can be made by either a cell process or a sheet process but the sheet process is more advantageous in terms of productivity and prices.
To make the sheet process possible, the touch sensor unit is coated with tempered glass but the strength of tempered glass gets lowered during the cutting process and this is the reason why new technologies should be developed such as technologies for increasing strength of sheet glass and tempered glass, cutting tempered glass, securing strength of tempered glass, and manufacturing thin film material and sheet for a touch sensor.
Industrialization: Development of the touch screen with integrated window for a smartphone began in January 2011 and was completed at the end of 2012 along with mass-production. The product began to be shipped to Company S in Japan from 2012, and the accumulated sales have reached KRW 125 billion.
In 2015, mass-production of a camera window, employing the same technology, succeeded through the sheet process, and supply of the product to Company S in Korea has led to sales of KRW 12 billion. This mass-produced product has applied GDP (Glass Direct Patterning) for the first time and allowed the company to be registered as a primary vendor for Company S. In 2016, the technology is applied to 0.1~0.2mm-thick tempered glass products such as a finger-scanning home key, whose sales are increasing in the market. This is expected to allow the company to increase export and to enter new markets.
Problem-solving in industrialization: It was not easy to introduce the new touch screen product to major smartphone brands without sales records from the establishment of the venture business in 2010. But the company has met quality requirements of a customer by developing samples a dozen times and won trust from a demanding Japanese customer by presenting meticulous plans for mass-production and installation of the necessary facilities.

Industrialization: The solution has won the project of establishing the AMI system and installing digital meters for 265,000 houses from Goteborg Energy, Sweden, using the technology for long-term system improvement and maintenance. This, in turn, has led to winning the capital AMI project, especially targeting apartment houses, as part of supplementary services using NURI Telecom’s electrical AMI. The technology was used to establish a wireless communication network providing energy IoT services to the entire city of Goteborg, which has become a well-known case of such industrialization. The system has proved the company’s outstanding technological competitiveness through continuous advancement & sophistication, and has recently won more contracts from South Africa, Ghana, India, and Iraq through the developed solutions or features with an effective proposal, applying the AMI system to a total of 1 million houses in 17 countries.
Industrialization: This technology has been applied to the Sejong U-City integration platform, Songdo u-disaster prevention integrated operation system, and the smart highway project of the Ministry of Land, Transport and Maritime Affairs. As for the Sejong U-City integration platform, the CEP (Complex Event Processing) engine, part of the project’s achievements, was used as a technological element for context- awareness and analysis. With regard to the Songdo u-disaster prevention integrated operation system, the CEP engine was used to collect and process in real-time mass event data coming from the air quality data collection system, installed in the Sunrise (Haedoji) Park, Songdo District, so as to produce the data of current or future environmental status. For the smart highway project of the Ministry of Land, Transport and Maritime Affairs, the platform collected data from various sensors (e.g. radar, CCTV, tolling, etc.) installed along the highways as well as vehicles, aiming to offer information on dangerous situations (icy road, obstacles, vehicle failure, etc.) through effective analysis of the data.
