In this study, we fabricated TN-LCD using DuoPIGatron ion beam with obliquely irradiated polyimide film and TN-LCD using conventional rubbing method, and compared the electro-optic characteristics. In the TN-LCD using the rubbing method, a pretilt angle of 0.05° was obtained, and it was confirmed that an excellent pretilt angle of 1.13° also occurred in the TN-LCD irradiated with an ion beam. In addition, voltage-transmittance characteristic, which is a characteristic for realizing gray scale, was measured using the TN-LCD manufactured as described above. And, the response time characteristic was measured as a basic feature to compose a screen without motion blur. As a result, both the TN-LCD using the rubbing method and the TN-LCD manufactured by ion beam irradiation showed good voltage-transmittance characteristics in the driving voltage range of 1.5–3.5 V. In particular, as a result of measuring the response time characteristics, the light-on time was measured at 5.11 ms and the light-off time was measured at 10.98 ms. This is a very good result at the level of TN-LCD without chiral dopant, which can be evaluated as comparable with the result of the production level.

电装应用中提高LCD生产率的离子束辐照对准工艺研究

在这项研究中，我们使用 DuoPIGatron 离子束和倾斜照射的聚酰亚胺薄膜制造 TN-LCD，并使用常规摩擦方法制造 TN-LCD，并比较了电光特性。在使用摩擦法的TN-LCD中，获得了0.05°的预倾角，并且证实在用离子束照射的TN-LCD中也出现了1.13°的优异预倾角。此外，使用如上所述制造的TN-LCD测量作为实现灰度的特性的电压-透射特性。并且，响应时间特性被测量为构成没有运动模糊的屏幕的基本特征。因此，使用摩擦法的 TN-LCD 和通过离子束照射制造的 TN-LCD 在 1.5-3.5 V 的驱动电压范围内都表现出良好的电压-透射特性。特别是，作为测量响应时间特性的结果，开灯时间测量为 5.11 毫秒，关灯时间测量为 10.98 毫秒。这在没有手性掺杂剂的TN-LCD水平上是非常好的结果，可以评价为与生产水平的结果相当。
