Abstract

We propose a novel plastic Liquid crystal display (LCD) with an ultra‐narrow‐border. As the most significant improvement, the four borders of the LCDs can be folded to wrap the backlight unit. This LCD was based on various new techniques, including the use of plastic substrates, processing of polarizer films, control of the neutral surface of a bending component based on the sealant width, and the use of a cover glass with a lens effect. We believe that these novel LCDs will be useful for numerous new applications.

6. 58‐1: Invited Paper:High Resolution IPS‐LCDs Fabricated with Transparent Polyimide Substrates

Author

Oka, Shinichiro, Hyodo, Yosuke, Jin, Lu, Yamaguchi, Yohei, Asozu, Genki, Higano, Emi, Higano, Toshiyuki, and Komura, Shinichi

Abstract

Plastic film IPS‐LCDs were fabricated with transparent polyimide (PI) substrates. Conventional transparent PI substrates have a large coefficient of thermal expansion and cause high retardation in thickness direction. We developed a new fabrication process and sheet design that improves upon these characteristics.

12. 15.5: Invited Paper: High Performance Autostereoscopic 2D/3D Switchable Display Using Liquid Crystal Lens.

Subjects

Abstract

We investigated an autostereoscopic 3D display using a Liquid Crystal Gradient Refractive Index (LC GRIN) lens, called LCL (Liquid Crystal Lens) 3D display. The characteristics of the LCL 3D display are high luminance and switchable 2D and 3D images by switching between the states of lens and non-lens. The LCL 3D display does not influence the 2D image quality. However, the crosstalk of the LCL 3D display is relatively high compared with other methods used in autostereoscopic 3D displays, such as barrier type, lenticular type, and so on. Therefore, we have investigated the reduction of crosstalk for the LCL 3D display. [ABSTRACT FROM AUTHOR]

Abstract

We investigate a 3D display using a Liquid Crystal Gradient Refractive Index (LC GRIN) lens and the factors needed to decrease crosstalk. Crosstalk in the latest 3D displays using LC GRIN lenses is 0.6%. [ABSTRACT FROM AUTHOR]

Abstract

The refractive index distribution of LC GRIN lenses for autostereoscopic 3D displays was investigated. It was clarified that the refractive index distribution forms a parabolic function of the optimum lens conditions. We achieved a minimum crosstalk of 0.6% in an autostereoscopic 3D display with an LC GRIN lens. [ABSTRACT FROM AUTHOR]
