THE BARRIER PART AND THE BARRIER CONTROLLING METHOD OF THE STEREOSCOPY DISPLAYING DEVICE WHICH CONSISTS OF THE PAIR-EYE TYPE EYE POSITION CALCULATOR, THE FAN-SHAPE MODIFIED LENTICULAR AND THE LIQUID CRYSTAL TYPE BARRIER

摘要

PURPOSE: A binocular eye position sensor, a barrier of a three-dimensional image display device using a fan-shaped lenticular barrier and a liquid crystal type barrier, and a control method thereof are provided to minutely control a path of light pointing from a scattering surface to an eye by matching the width of the scattering surface with the width of the barrier. CONSTITUTION: A liquid crystal type barrier comprises a group circuit for controlling an electric circuit and the electric circuit corresponding to a liquid crystal. A liquid crystal part of the liquid crystal type barrier is composed of liquid crystals minutely arranged according to the width of a scattering surface composing RGB(Red Green Blue) image pixels. A control part of the liquid crystal barrier controls the liquid crystal. The control part is composed of a single integrated circuit of a plurality of integrated circuits.
