As next generation display, TFT LCD gets into the spotlight, and the bigger glass size is required. Currently, its display size is 1500 mm by 1870 mm at the six generation comparing with 300mm by 400 mm at the first one and the size is increasing continuously, which cause the difficulties to apply the cleaning operation including the general brush cleaning. In this study, water-jet cleaning operation has been introduced, which spent the less water them other cleaning methods. Throughout the experiment, is has been found the possible damage of the declined cell and the variation of the tilt bias angle depending upon the increasing time. In addition, the simulation predicts the glass bending of the display.

This paper is a thesis on media art technology for high-tech performances and exhibitions. After creating an interactive stroke in VR, it is projected in real time through a media facade technique. Among our traditional dramas emphasizing linear movements, movements were extracted from the Bongsan mask dance, and the movements of the lines were used in a media art performance called 'Multi-face Convergence'. When motion data enters the virtual space, geometry consisting of faces is created in the VR space. The created strokes can be set with various brush types, and when performing, a stroke with a red fire effect that matches a dynamic movement was used. It was made to be able to harmonize with the dancers performing the Bongsan mask dance. The medium called VR has characteristics that are not suitable for melting into a performance, but in this performance, it has overcome its limitations by using a technique called media façade. We propose the world's first performance technique that combines interactive strokes with traditional dance performances.

The purpose of this paper is to explain the recipient's psychology, which results from the operation of media, from the perspective of the fluctuation between immersion and contemplation. Media allow to perceive and speculate about specific objects or meanings. In addition, the media perform the function of expanding or changing the objects of perception and thought. McLuhan or Luhmann's media theory emphasized this function of changing the state of perception by inducing a contemplative attitude. This notion is exemplified by interpretation of the visual media history. In this paper, the cases of film and computer game are discussed. In particular, it is considered that VR media causing strong immersion have also developed in a way that allows recipients to contemplate an virtually constructed reality. The commercialization of Tilt Brush and the experimentation of VR painting artwork are the examples for this dual development.

With the advancement of technology, there are almost no constraints on expression in virtual reality (VR) art; however, it still has some limitations. VR artists can be largely classified into two groups in terms of style. The first group is artists who create their works as a live performance. In this case, a major limitation is that the artist cannot see how the audience reacts to the work because he/she wears a VR device while performing, and the audience cannot fully experience the work, since they view it only on-screen without any VR devices. This problem can be solved if all members of the audience wear VR devices; however, that requires astronomical costs and brings about another problem related to device management. If the price of VR devices decreases as technology develops, it may help solve this problem. The second group is exhibition artists who regularly display their works online. In this case, the limitation is that their work using VR remains only in the virtual digital space. In this case, a solution may be creating space in exhibition halls, and providing VR devices to audience members in existing art exhibitions.
