A large amount of processing time is required if the process of detecting the touch position on the touch screen and displaying it on the display panel is performed only by software. In this paper, we propose a method to output information touched on the screen using H/W method in order to improve the response speed delay. In the FPGA module designed for the HDMI signal output to the display module, the touch information is input to the serial data signal including touch coordinate information, point size, and color information. Then the module render the image using HDMI signal input to the module and the touch information. This method has a pipeline structure so it has effect of reducing the delay time that occurs in outputting the touch information compared with the conventional software processing method.

In this study, we investigated the electrical, optical, structural, and surface properties of indium zinc oxide (IZO)/Ag/IZO multilayer electrode grown by specially designed roll-to-roll sputtering system using the flexible substrate. By the continuous roll-to-roll sputtering of the bottom IZO, Ag, and top IZO layers at room temperature, they were able to fabricate a high quality IZO/Ag/IZO multilayer electrode. At optimized conditions, the bottom IZO layer (40 nm) was deposited on a flexible substrate. After deposition of the Bottom IZO layer, Ag layer was deposited onto the bottom IZO film as a function of DC power (200~500 W). Subsequently, the top IZO layer was deposited onto the Ag layer at identical deposition conditions to the bottom IZO layer (40 nm). We investigated the characteristics of IZO/Ag/IZO multilayer electrode as a function of Ag thickness. It was found that the electrical and optical properties of IZO/Ag/IZO multilayer electrode was mainly affected thickness of the Ag layer at optimized condition. In case of IZO/Ag/IZO multilayer electrode with the Ag power (350W), it exhibited a low sheet resistance of 7.1 ohm/square and a high transparency of 86.4%. Furthermore, we fabricated the touch screen panel using the IZO/Ag/IZO multilayer electrode, which demonstrate the possibility of the IZO/Ag/IZO multilayer electrode grown by roll-to-roll sputtering system as a transparent conducting layer in the touch screen panel.

In this study, we investigated the reliability of anisotropic conductive paste (ACP) and anisotropic conductive films (ACF), which are anisotropic conductive adhesives, applied to automotive touch panels. Adhesive material is also important as a key factor in assembling the touch panel. In order to measure the resistance change of the parts in two kinds of high temperature test, the reliability of the two types of anisotropic conductive adhesives was compared and evaluated through the results of the resistance change. For 615 hours of reliability testing, the anisotropic conductive film exhibited a higher stability in a high temperature environment than the anisotropic conductive paste.

In this paper, we described the integrated monitoring system for low-voltage panel boards. This system consists of three parts, a panel board controller, an integrated monitoring unit and a remote PC. The panel board controller which was made of CT/PT unit, control unit and power supply is able to transmit variable parameter for monitoring and diagnosis of low voltage branch circuits. Also, the integrated monitoring unit was collected monitoring data from panel boards and displayed on the touch panel.

Gravure off-set printing recently is used in electronics display market. This method has advantages of mass production and high printing speed. It is also fine pattern can be implemented. We have manufactured low-curable conductive Ag pastes for gravure off-set printing. When printing, the pastes be used different silver powder shape because of the printing characteristics. The pastes were prepared with silver powder by silver powder shape and size, epoxy resin, solvent and homogenized on a standard three-roll mill. And the pastes exhibited a shear-thinning flow at viscosity profile. Moreover the adhesive strength and resistivity of silver film had a good characteristics. With the manufactured paste in this study, touch panel had is manufactured and it had $4{\times}10-5{\Omega}.cm$.

A new hybrid-type touch screen panel (TSP) has been developed based on a-Si:H TFT which can detect the change of both $C_{LC}$ and photo-current. This TSP can detect the difference of $C_{LC}$ between touch and no-touch states in unfavorable conditions such as dark ambient light and shadows. The hybrid TSP sensor consists of a detection area which includes one TFT for photo sensing and two TFTs for amplification. Compared to a single internal capacitive TSP or an optical sensing TSP, this new proposed hybrid-type TSP enables larger sensing margin due to embedding of both optical and capacitive sensors.

We present a new touch screen method, which utilizes the variation of liquid crystal capacitance according to the touch event on the screen. It is integrated in the AMLCD with the conventional LTPS process. Its resolution is same as the display resolution as well as performs the multi-touch sensing function basically. The design concept and the operation are verified with the SPICE simulation.

본 논문은 모바일 터치스크린을 이용한 필기체 문자 인식 알고리즘을 제안하고, 구현된 내용을 기술한다. 제안된 시스템은 PXA320 프로세서, 정전 용량 터치 패널과 QT4를 이용한 인터페이스로 구성하였다. C++ 언어를 사용하고 제안된 알고리즘은 문자의 특성을 직선, 좌호, 우호 특징을 추출하여 3진 트리 방식으로 입력되는 문자를 결정한다. 영문자에 대한 테스트를 통하여 성능을 검증하였다. 기존 방식보다 간단한 알고리즘으로 구성되므로, 모바일 터치 스크린의 문자인식에 적용이 가능하다.
