P‐117: The Transmittance Study of the Photo Alignment FFS LC Mode

SID Symposium Digest of Technical Papers (2015)

Yongchao Zhao Chung‐Ching Hsieh Yanjun Song Xiang Li Ren‐Tang Zhao

We have investigated a photo alignment material for fringe field switching (FFS) liquid crystal display and it has good alignment performance. It realizes alignment by irradiating linearly polarized light with wavelength of 254nm. We have investigated the factors that affect the transmittance in photo alignment FFS mode. The transmittance becomes smaller with the alignment angle increasing. The transmittance is also affected by the L/S width of the ITO electrode, it becomes smaller with the L/S increasing. The LC type also affect the transmittance, we can get higher transmittance using negative LC.

P‐116: The Investigation of In‐Plane Liquid Crystal Photo‐Alignment Technology for Large Size Panel

SID Symposium Digest of Technical Papers (2015)

Yanjun Song Chung‐Ching Hsieh Yongchao Zhao Ren‐Tang Zhao Xiang Li

A new photo alignment material for fringe field switching (FFS) and in‐plane switching (IPS) liquid crystal display has been presented and it has good alignment performance. It realizes alignment by irradiating linearly polarized light with wavelength of 365nm. We have investigated the effect of UV dosage and anneal process on the alignment ability and optical performance. An excellent dark state and image sticking property can be achieved by optimized photo alignment conditions.
