  • Objective: The aim of this study was to predict human performance time in finding objects on multi-display monitors using ACT-R cognitive architecture. Background: Display monitors are one of the representative interfaces for interaction between people and the system. Nowadays, the use of multi-display monitors is increasing so that it is necessary to research about the interaction between users and the system on multi-display monitors. Method: A cognitive model using ACT-R cognitive architecture was developed for the model-based evaluation on multi-display monitors. To develop the cognitive model, first, an experiment was performed to extract the latency about the where system of ACT-R. Then, a menu selection experiment was performed to develop a human performance model to find objects on multi-display monitors. The validation of the cognitive model was also carried out between the developed ACT-R model and empirical data. Results: As a result, no significant difference on performance time was found between the model and empirical data. Conclusion: The ACT-R cognitive architecture could be extended to model human behavior in the search of objects on multi-display monitors.. Application: This model can help predicting performance time for the model-based usability evaluation in the area of multi-display work environments.

  • In this paper, our research efforts and activities for displaying flight simulation graphics on multi-monitors connected to a Linux cluster is introduced. In this pilot system graphics rendering as well as view calculation including LOD implementation for each monitor is peformed on each sub-node computer connected to the monitor rather than using an expensive main server. The Linux cluster is constructed by combining general-purpose desktop computers, and MPI library Is used for communication between sub-nodes. It could be concluded from our experience that it is possible to construct a massive multi-monitor display system by adding to the cluster as many sub-node computers and monitors as possible with economic efficiency.

  • This paper presents a new technology, Advanced Dynamic Capacitance Compensation (A-DCC), for improved dynamic performance of LCD monitors. Conventional LCD monitors suffer from certain specific artifacts, such as wire-frame flicker and line dimming, which are not an issue for the simpler motion images found in television content. A-DCC addresses these more challenging monitor cases through an advanced architecture which analyzes multi-frame data and applies more comprehensive lookup table corrections according to the specific frame sequence.

  • 비디오 월 컨트롤러는 여러 개의 모니터를 연속적으로 배치하여 하나의 큰 스크린으로 표출하는 특수한 형태의 멀티 모니터를 가진다. 멀티스크린에 여러 영상을 동시에 표출하고자 하는 경우, 운영자는 표출할 영상과 모니터를 미리 매핑하여 저장한다. 멀티스크린의 모니터 개수가 많지 않은 소규모의 시스템에서는 영상과 모니터의 매핑 작업이 단순하지만, 모니터의 개수가 늘어날수록 매핑의 경우의 수가 늘어나므로 업무효율이 저하된다. 이에 본 논문에서는 연관 규칙 기반의 학습을 이용하여 영상을 표출할 모니터를 추천하여 매핑 작업의 효율성을 향상시키는 모델을 제안한다.

  • We have developed a high performance vertical alignment TFT-LCD (Thin Film Transistor Liquid Crystal Display), that shows a high light transmittance, and wide viewing angle characteristics with an unusually high contrast ratio. In order to optimize the electro-optical properties we have studied the effect of cell parameters, multi-domain structure and retardation film compensation. With the optimized cell parameters and process conditions, we have achieved a 24" wide UXGA TFTLCD monitor (16:10 aspect ratio 1920X1200) showing a contrast ratio of over 500:1, panel transmittance near 4.5%, response time near 25 ms, and viewing angle higher than 80 degree in all directions.

  • We developed new WV-TN panel which has 170/170 viewing angle and 8ms response time. This viewing characteristics almost catch up with those of VA. To extend the viewing angle we optimized the cell design and LC parameters. This new technology strongly increase the demand of TN monitors especially for the monitor market larger than 19"

  • 최근 디지털 사이니지 기술은 정방형 디스플레이로 콘텐츠를 표출 뿐만 아니라 다양한 형태와 크기를 가진 비정형 디지털 사이니지로 발전하고 있다. 고해상도의 대형 모니터들을 연결하여 다양한 조합을 이루는 멀티비전 형태로 표현하고 있다. 본 논문에서는 멀티디스플레이의 회전에 따라 ROI가 독립적으로 변하는 비정형 디스플레이 사이니지 시스템의 구조를 제안하였다. 아두이노와 연동된 자이로 센서의 출력 값을 입력으로 받아 모니터의 기울어진 각도를 계산하고, 극좌표계의 특성을 이용하여 회전되는 각도에 따라 네 꼭짓점의 위치가 가변되는 영상을 영상좌표계로 변환하여 회전형 사이니지를 구현하였다. 또한 멀티 스크린 환경에서 화면을 표출하기 위하여 자이로 센서가 부착된 다수의 디스플레이를 아두이노의 시리얼 통신을 이용하여 제어하였다.

  • 아날로그 모니터를 사용하는 디스플레이 시스템의 경우, 프레임 버퍼의 영상 정보 갱신 주기와 모니터 주사 주기가 맞지 않는 경우, 장면 변화가 심한 동영상 디스플레이시에 화면이 상단과 하단으로 다른 영상이 나타나는 tearing 현상이 발생한다. 다중 카메라 채널을 디스플레이하여야 하는 영상 감시 시스템인 DVR(Digital Video Recorder) 시스템에서는 프레임 버퍼 갱신율이 매우 높기 때문에 tearing 현상이 심하게 된다. 본 논문에서는 윈도우즈 기반 DVR에서 디스플레이 속도 성능의 저하가 별로 없으면서, tearing 현상을 방지한 개선된 디tm플레이 시스템 구조를 제안한다. 제안된 디스플레이 시스템의 효율성은 실험을 통하여 입증하였다.

  • Cold cathode fluorescent lamp (CCFL) has been used as a light source for direct type backlights for LCD monitors or TV. One inverter for one CCFL was necessary for maintaining the lamp current so that many inverters were used to drive as many CCFLs of direct type backlight for LCD TV. An inverter for driving 16 CCFLs was developed to reduce the backlight cost. The length and diameter of CCFL were 450mm and 4mm, respectively. Backlight including 16 CCFLs for 26" LCD TV was assembled by using one inverter. The uniformities of the assembled backlight operated by the conventional inverter and the newly developed inverter were 75% and 88%, respectively.
