Abstract

A new wide viewing angle liquid crystal device was developed using PET technology.The liquid crystal molecule was twisted by double electric field.The rising time of the design with negative liquid crystal is slightly greater than the positive's,and the falling time is accordance with the positive liquid crystal.Compared with positive liquid crystal,the transmittance is increased about 10%.The relationship of transmittance with response time and voltage,was analyzed in the effect of three electrodes.The wide viewing angle technology monopoly of FFS and IPS was effectively solved.

Abstract

The design of high speed digital video storage system based on 64-bit operation system is discussed because ultra high frame-rate and high pixel number digital cameras are widely used in the field of optical measurement.This system uses high performance PC as hardware platform and high capacity memory is carried.The software puts image and appendix data into cache in memory during the storage process and after the process the software writes the data into hard disks array.The choke point in unstability of data transfer speed of the increasing number of hard disks is overcomed.According to application the bandwidth can exceed 800 Mbyte/s and the expected result is obtained.
