점차 고성능화 되어가는 Display 제품들을 더욱 저렴하고 일반화하기 위해 제품 공정수를 줄이고 설계 기간을 단축하여야 한다. PCB(Printed Circuit Board) 층수(Stack-up)를 줄이고 회로개발 면에서는 회로를 간략히 하고 부품소자를 최소화하여야 한다. 그리고 기구개발 면에서는 공정을 최소화하고 견고하게 하는 것이 시장 추세이다. 불량 없으면서 초단납기 설계와 대량 생산을 위해 일원화를 추진하고 있다. 곧, 어떤 Customer에게 나가도 A/S 문제가 발생되지 않도록 초기부터 적용하는 최적설계가 필요하다. 본 연구는 Display의 대표라 할 수 있는 PDP(Plasma Display Panel)를 CAE(Computer Aided Engineering)를 이용해 설계함으로써 PDP 회로 최적설계를 하는데 CAE의 활용 사례를 알 수 있다.

In this paper, we introduce the novel idea to improve parallel test efficiency of semiconductor test. The idea includes the test interface card consisting of NoC structure able to transmitting test data regardless of ATE speed. We called the scheme "Multi-Clock" mode. In the proposed mode, because NoC can spread over the test data in various rates, many semiconductors are tested in the same time. We confirm the proposed idea will be promising through a FPGA board test and it is important to find a saturation point of the Multi-Clock mode due to the number of test chips and ATE channels.

Electronic display markets has been developed. The cathode ray tube of brown form recently celebrated their 100th by first display. Also LCD of flat form recently celebrated their 25th by second display and it has advantage of small volume, lower consumption power. But FPD has problem that is property of brittle and noncarrying by glass substrate. Therefore the arrival of portable electronics devices has put an increasing premium on durable, lightweight and inexpensive display components. It is flexible display by third display. Also electronics field such as printed wiring board, RFID, membrane switch prefer flexible display. The conductive pattern can be used mostly in field of electronic displays and electronics. This manufacture of conductive pattern in present used is screen printing. The the conductive pattern. It has advantages of flexibility, high conductivity, drying in low temperature, good conductivity. screen printing has problem that is low productivity and use not flexible substrate because of high fire temperature. This study was developed novel method to form the conductive pattern. It has advantages of flexibility, high conductivity, drying in low temperature, good conductivity.

Recently, new interfaces such as virtual reality and augmented reality are being developed by the development of IT technology. In particular, virtual / augmented reality technology is being applied to training equipment for members in special environments such as defense and fire fighting. In this paper, we implemented a display image processing board for HMD which is applicable to firefighter's helmet. We developed a technology to visually provide various information to firefighters in case of fire fighting.

Digital FHR monitoring system based on the personal computer combined wi th the digital signal processing (DSP) board was implemented. The DSP board acquires and digitally processes ultrasound fetal Doppler signal for digital rectification, envelope detection, autocorrealtion function calculation and its peak position detection. The personal computer interfaced with the DSP board is in charge of graphic display, hardcopy, data taransmission and on-line analysis of fetal heart rate change including on-line warning system, base-line estmation, acceleration, deceleration and variability. The advantages of PC-DSP based system can be summarized as follows: 1) Minimum hardware realization. 2) Increased flexibility. 3) Total care system.

Digital fetal monitoring system based on the personal computer combined with the digital signal processing (DSP) board was implemented. The DSP board acquires and digitally processes ultra- sound fetal Doppler signal for digital signal conditioning, rectification, low -pass filtering, autocorrealtion function calculation and its peak detection. The personal computer interfaced with the DSP board is in charge of graphic display, hardcopy, data transmission and on -line analysis of fetal heart rate change including on - line warning system, base -line estmation, acceleration, deceleration and variability. It is one of the most suitable situation to apply the DSP chip for siganl conditioning, digital filtering of ultrasound fetal Dopier signal and fetal heart rate estimation using autocorrelation technique .

Notifying emergency evacuation methods, accurate disaster location and evacuation route guidance can be very active alternatives to quickly minimize evacuation and casualties in disaster situation in the development of subway disaster prevention detection system that detects the disaster signs at the subway station early on the basis of Internet of things and leads passengers to evacuate. It's not easy to ensure perfect functioning of fire fighting facilities and equipments due to underground space structure with narrow exits. Therefore, we developed disaster provision EL Display integrated board that can induce the most efficient evacuation and the field experiment was conducted to examine the practical application in this study. Especially the applicability was verified by field application test because there is no case in which EL panels are used to evacuate disasters.
