Lately a color field sequential LCD is widely noticed because it requires no micro-color-filter.To realize the color field sequential LCD in the direct view type, we adopted an OCB mode which can be obtained fast response and uniform alignment in large area, and a low-temperature p-Si TFT which can be possible scanning high speed and fabrication large size. Further, we optimize the driving method, and obtain good display condition in a trial-fabrication of 4 inches size color field sequential LCD.

Abstract— A new display method for field‐sequential‐color liquid‐crystal displays (FS‐LCDs) that reduces the negative effects of color break‐up associated with moving objects has been developed. The method is called Adjustment of Color Element on the Eyes (ACE), and it relies on the position on the eyes of RGB color sub‐images. It was confirmed that color break‐up also does not occur for peripheral objects when using ACE.

Field sequential color LCDS require an LC‐mode with a fast response time. For this purpose, we have studied an OCB Optical Compensated Birefringence mode that is capable of displaying a gray‐scale with high‐speed response. However, this mode exhibits a splay alignment at initial state. It requires transition from the splay alignment to bend alignment before drive, while it takes a relatively long time in general. To solve this problem a new method is proposed. It employs an optimized TFT‐array structure with a low‐temperature p‐Si TFT‐LCD and a high DC voltage is applied to a common electrode at initial state. This new method enable the initial transition to be less than 3 sec and no defective pixel remains.

Abstract— A novel front‐light system that uses an organic light‐emitting‐diode (OLED) light source patterned with a fine pitch has been developed. The front‐light system has the following characteristics: (1) excellent uniformity within the light‐emitting area; (2) emittance that is consistent at all viewing angles; (3) no light leakage at any viewing angle from the side of the observer. This system can be adopted for reflective LCDs, electrophoretic displays (EPDs), microelectromechanical systems (MEMS), and other applications.

We have been developing a front-light system that uses an OLED light source patterned with a fine pitch. This system can be used in reflective LCDs, electrophoretic displays (EPD), microelectromechanical systems (MEMS) and other applications. In this paper, we present a new structural design for an OLED frontlight system. In the new system, the space between a pair of glass substrates is filled with resin, and a pattern of black resin is formed on the counter-substrate such that it corresponds to a pattern of Al cathodes. The new system has excellent characteristics as a front-light. Light is used more efficiently than in the conventional design, and the reflection of ambient light can be avoided.
