摘要: | 为了得到更自然的立体影像,近年来已有许多专家及厂商投入立体显示器的发展。大多数立体显示器使用固定式的光学元件,但此种显示器仅能提供3D影像,无法提供2D影像。因此,可切换2D、3D影像显示器的发展便显得重要。 本论文提出的主动式液晶透镜(Active-TFTs Liquid Crystal Lens)可应用于2D、3D影像的切换,也可应用于3D旋转式萤幕,又或者是区域性的2D、3D切换。此篇将藉由半导体特性形成的开关,以及高阻值材料层的液晶透镜,来达到区域性的2D、3D切换。透过闸极与源极输入电压,便可决定哪一个透镜的中央电极将被充电。关闭输入电压后,若与两旁电极无压差,则无透镜效果,反之亦然。主动层以及液晶层的电性将会影响充放电的时间,其中又以漏电流最影响放电时间,进而影响液晶透镜的持续时间。利用退火得到好的主动层电性,再利用储存电容延长放电时间,如此一来便能达到区域性的2D、3D切换,使得未来立体显示器功能上有更多发展的可能性。 Recently, many researchers invest in developing 3D display technology to produce much natural images from displays. Since most of display applications use the fixed optical components to display 3D images, the 2D images cannot be provided by the same displays. Thus, a 2D/3D switchable display is needed. In this thesis, we designed an Active-TFTs Liquid Crystal Lens for multifunctional 3D display such as, 2D/3D switchable、3D rotatable、2D/3D localized. For the on/off switch characteristics of semiconductor and high resistance liquid crystal lens, the 2D/3D localized LC lens could be obtained. By applying individual voltage on gate and source electrodes, the decided drain electrodes will be charged. Once turning off the applying voltage, if there is no potential difference between two electrodes, there won’t have lens effect, and vice versa. The electrical properties of LC layer and active layer will affect the charging and holding state. The annealing process and storage capacitor can enhance the lens holding time. This makes the Active-TFTs LC lens become more potential for applying in 3D display such as 2D/3D localized. |
