In this paper we present work done by Kodak Graphic-Communications-Group and our partners demonstrating applications where laser direct imaging could replace photolithography in display manufacturing. Such applications range from direct manufacturing (e.g. LCD color-filters) to producing “masters” where manufacturing is done by traditional printing methods (e.g. flexography, Gravure-printing).

We implemented PanelLlnk digital flat panel display transmitter supporting SXGA($1280{\times}1024$) resolution. It can transmit data through 10m cable at XGA($1024{\times}768$) resolution and through 7m cable at SXGA($1280{\times}1024$). We also found resistor value to get stable display image by low voltage differential signal swing control.

Digital Twin technology is rapidly transforming various industries by providing comprehensive virtual models that replicate physical objects or processes. In the context of agriculture, digital twin can be a game-changer. This technology can help in creating precise simulations of farming scenarios, thereby enabling farmers to make data-driven decisions and optimize farm operations. The potential benefits include improved crop yields, resource efficiency, and environmental sustainability. However, the implementation of digital twin technology in agriculture poses challenges, such as data management issues and the need for robust IoT infrastructure. Despite these hurdles, the future of digital twin in agriculture looks promising, with ongoing research and developments aimed at overcoming these obstacles.

In this paper, a new method for controlling the pointing device on digital display using EOG(electrooculogram) which is generated from eye movement, was suggested. The manufactured system is consisting of pre-amplifier, A/D converter, serial transmission device and PC program. The EOG is amplified by pre-amplifier. And the amplified EOG is digitized and transmitted to personal computer via rs-232c by PIC16C74A. Finally, the software for controlling the pointer on digital display is developed on computer. As the result, the error between the real subject's viewing point and the point indicated by the developed pointing device on digital display was investigated into the average value, 0.72 degree for horizontal axis, 0.96 degree for vertical axis. The pointing device developed in this study is controlled by subject's eye movement, that is, the user's intention. Furthermore, the algorithm of this study is applicable for many field such as a new method remote control, a new wheelchair control and so forth.

The traditional outdoor advertising market has been stagnant recently, but the digital advertising market has been steadily increasing, and the digital signage market has been expanding despite the recent corona pandemic. However, in terms of hardware, new displays are required due to excessive power consumption, lack of visibility in sunlight, and continuous operating expenses. Since the e-paper display does not require a light emitting device therein, it is advantageous to solve above problems. In addition, it has the advantage of consuming power only when converting an image due to bistability, so it is suitable as hardware that implements images rather than moving pictures. Currently, one of the most successful examples of commercializing e-paper displays is ESL devices. According to a recent market study, the market for large-sized panels larger than 10 inches has grown at an annual rate of 21.6%, and the market is expected to exceed 30% by 2026. It is judged that it will be relatively easy to apply the roll-to-roll technology, which is currently developing the technology applied to OLED, to the e-paper display. Therefore, mass production technology and market expansion for ESL panel enlargement are expected, and a new market is also expected to be formed at the same time. New markets will be traffic signs, public displays, billboards, façades, kiosks, digital signage, and so on.

In this paper, a low-csst ECG system using a digital filter was implemented. After amplifying the analog ECG signal, it is converted into a digital signal and filtered. The developed ECG module is miniaturized by removing the analog filter element that occupies the existing volume and replacing it with a digital filter using a 3-stage Butterworth filter which is one of IIR filters. It uses a serial monitoring program with C# to check and save the ECG waveform measured on a computer screen. The ECG system using a developed digital filter in this paper uses a low-cost processor instead of an expensive, high-end processor, and its size and price are reduced by converting the analog filter to a digital filter. In addition, since the waveform of the developed ECG system is similar to the actual ECG waveform of MIT-BIU, it is considered that the existing analog filter can be replaced with the developed digital filter.

Digital holography is a computational operation and photo-electronic technology that enables calculating, encoding, and reconstructing a 3D scene based on the interference of a coherent light-wave field. The spatial light modulator in a holographic 3D display decodes a computer-generated hologram to optically regenerate a 3D scene in various depths, thus facilitating to match convergence and accommodation of the human eyes. This paper introduces recent technologies related with the content for digital holography called an ultimate 3D display.

The Capacitor DAC with gamma correction is proposed for TFT-LCD (Liquid Crystal Display) driver application. It is based on two ideas. First, 6bit digital code is converted 8bit digital code by memory circuit (Look Up Table) for gamma correction. second, weighted voltage ratio DAC is proposed for reducing area and power consumption.
